Creating an auto filter code - vba

Good Morning,
I am considerable new to VBA and was looking for some assistance on writing an auto-filter code for my table.
Tariffs | SME100 | Enterprise | CustomerLoyalty | AccountManage
------------+-----------+---------------+-------------------+-------------------
Voda Red | 1 | 1 | 0 | 1
Voda 1G D | 1 | 0 | 1 | 0
1* eligible to sell
0* not eligible sell
I am trying to write a code that takes the value from a validation box ("B2") and automatically filters the specific column of that sales channel for the eligible tariffs. My current code is:
Sub Filter()
Dim strRange As String
strRange = "B"
Dim b As Integer
b = "2"
Range = ActiveSheet.Cells(2, 2).Address(False, False)
If Range = True And Range = "SME100" Then
ActiveSheet.ListObjects("TariffTable").Range.AutoFilter Field:=2, Criteria1:="1"
If Range = True And Range = "Enterprise" Then
ActiveSheet.ListObjects("TariffTable").Range.AutoFilter Field:=3, Criteria1:="1"
If Range = True And Range = "CustomerLoyalty" Then
ActiveSheet.ListObjects("TariffTable").Range.AutoFilter Field:=4, Criteria1:="1"
If Range = True And Range = "AccountManagement" Then
ActiveSheet.ListObjects("TariffTable").Range.AutoFilter Field:=5, Criteria1:="1"
Else
MsgBox ("No Sales Channel Selected")
End If
End Sub
Any advise will be much appreciated

I would approach it in a different way:
Sub Filter()
Dim columnNumber, tableRow, tableColumn, tableWidth As Integer
Dim tableName, columnName As String
tableName = "Table1"
columnName = ActiveSheet.range("B2").Value
'This clears the existing filter
ActiveSheet.ListObjects(tableName).range.AutoFilter
'Assign some numbers we need to know about the table to check the headers
tableRow = ActiveSheet.ListObjects(tableName).range.Row
tableColumn = ActiveSheet.ListObjects(tableName).range.Column
tableWidth = ActiveSheet.ListObjects(tableName).range.Columns.Count
'If a column title with the specified value does not exist VBA throws an error which we need to catch, this is one of the many reasons I dislike VBA :D
On Error GoTo ErrorHandler
'Search through the table column header row to find the specified column and assign the number to columnNumber
columnNumber = Application.WorksheetFunction.Match(columnName, range(Cells(tableRow, tableColumn), Cells(tableRow, tableColumn + tableWidth)), 0)
'Apply the filter "1" to the found columnNumber
ActiveSheet.ListObjects(tableName).range.AutoFilter Field:=columnNumber, Criteria1:="1"
'Exit the sub otherwise the "error handling" will be provoked
Exit Sub
ErrorHandler:
MsgBox columnName & " does not exist"
End Sub
Edit: Plus you should read and understand sancho.s's answer.

I suggest modifications, checks, etc.:
You probably need Range = ActiveSheet.Cells(2, 2).Text (or using a different name, see below). This is likely the source of error. Plus, there is a lot to improve in your code.
Use Dim colstr as String, colstr = ... instead of Range = ....
Make sure TariffTable is correctly defined.
AccountManagement should read AccountManage.
Make sure ActiveSheet refers to the Sheet you want to work with.
Inquire If colstr = "Enterprise" Then instead of If colstr = True And colstr = "Enterprise" Then (already using a changed name).
You can improve over using multiple Ifs, e.g., with Select Case, or even matching colstr against the Range containing the headings.
PS: You did not post the output/errors of your code.

Perfect user input validation in Excel VBA

I need to validate user input on when cells change and show the error in another cell in Excel using VBA.
I run into problems where my validator is called on all cells in the sheet when a user inserts rows or column which makes Excel unresponsive for a long time, how can I fix this?
Below are my requirements and my current solution with full documentation.
Definition and requirements
Consider the following table:
Example User Input Table
| | | Tolerance | | |
| Type | Length | enabled | Tolerance | Note |
|------|--------|-----------|-----------|----------------------------|
| | 4 | 0 | | Type is missing |
| | | 0 | | Type is missing |
| C | 40 | 1 | 110 | |
| D | 50 | 1 | | Tolerance is missing |
| | | | | |
The idea is that the user inputs values in the table, once a value has been changed (the user leaves the cell) the value is validated and if there is a problem the error is printed in the Note column.
Blank lines should be ignored.
I need this to be robust meaning it should not fail on any user input, that means it has to work for the following cases:
Paste values
Delete rows
Insert rows (empty or cut cells)
Insert/delete columns *
Any other case I missed thinking about?
*It is OK if the the validation fails when a user is deleting a column that is part of the table as this is seen as the user willfully vandalizing the sheet, but it has to fail gracefully (i.e. not by validating all cells in the worksheet which takes a long time). It would have been great if this action was undoable, however my current understanding of Excel suggests this is impossible (after a macro has changed something in the sheet, nothing can be undone anymore).
The Note cell can only contain one error at a time, for the user the most relevant error is the one for the cell the user last changed, so it should display this error first. After the user fixes that error the order is not that important anymore, so it could just display the errors from left to right.
Problems with current approach
My problem is that when rows/columns are inserted validation is triggered for all cells in the sheet which is a very slow process and to the user it looks like the program has crashed, but it will return once the validation is complete.
I don't know why Excel does this but I need a way to work around it.
Code placed in a Sheet named 'User Input'
My solution is based on the only on change event handler I know of: the per sheet global Worksheet_Change function (ugh!).
Worksheet_Change function
First it checks if the changed cell(s) intersects with the cells I'm interested in validating. This check is actually quite fast.
OldRowCount here is a try to catch the user inserting or deleting cells depending on how the used range changes, however this only solves some cases and introduces problems whenever Excel forgets the global variable (which happens now and then for as to me unknown reasons) as well as the first time the function is run.
The for loop makes it work for pasted values.
Option Explicit
Public OldRowCount As Long
' Run every time something is changed in the User Input sheet, it then filters on actions in the table
Private Sub Worksheet_Change(ByVal Target As Range)
Dim NewRowCount As Long
NewRowCount = ActiveSheet.UsedRange.Rows.count
If OldRowCount = NewRowCount Then
If Not Intersect(Target, Me.Range(COL_TYPE & ":" & COL_TOLERANCE)) Is Nothing Then
Dim myCell As Range
' This loop makes it work if multiple cells are changed, for example while pasting cells
For Each myCell In Target.Cells
' Protect the header rows
If myCell.row >= ROW_FIRST Then
checkInput_cell myCell.row, myCell.Column, Me
End If
Next
End If
ElseIf OldRowCount > NewRowCount Then
'Row deleted, won't have to deal with this as it solves itself
OldRowCount = NewRowCount
ElseIf OldRowCount < NewRowCount Then
Debug.Print "Row added, TODO: deal with this"
OldRowCount = NewRowCount
End If
End Sub
Code placed in a module
Global variables
Defines the rows/columns to be validated.
Option Explicit
' User input sheet set up
Public Const ROW_FIRST = 8
Public Const COL_TYPE = "B"
Public Const COL_LENGTH = "C"
Public Const COL_TOLERANCE_ENABLED = "D"
Public Const COL_TOLERANCE = "E"
Public Const COL_NOTE = "G"
Cell checking function
This function validates the given cell unless the row where the cell is is empty.
Meaning we are only interested in validating cells on rows where the user has actually started giving values. Blank rows is not a problem.
It first validates the currently changed cell, if it is OK it will then validate the other cells on the given row (since some cells validation depends the values of other cells, see Tolerance enabled in my example table above).
The note will only ever contain one error message at a time, the above is done so that we always get the error of the last changed cell in the Note cell.
Yes, this will make the checker run twice on the current cell, while it is not a problem it could be avoided by a more complex if statement, but for simplicity I skipped it.
Sub checkInput_cell(thisRow As Long, thisCol As Long, sheet As Worksheet)
Dim note As String
note = ""
With sheet
' Ignore blank lines
If .Range(COL_TYPE & thisRow).value <> "" _
Or .Range(COL_LENGTH & thisRow).value <> "" _
Or .Range(COL_TOLERANCE_ENABLED & thisRow).value <> "" _
Or .Range(COL_TOLERANCE & thisRow).value <> "" _
Then
' First check the column the user changed
If col2Let(thisCol) = COL_TYPE Then
note = check_type(thisRow, sheet)
ElseIf col2Let(thisCol) = COL_LENGTH Then
note = check_length(thisRow, sheet)
ElseIf col2Let(thisCol) = COL_TOLERANCE_ENABLED Then
note = check_tolerance_enabled(thisRow, sheet)
ElseIf col2Let(thisCol) = COL_TOLERANCE Then
note = check_tolerance(thisRow, sheet)
End If
' If that did not result in an error, check the others
If note = "" Then note = check_type(thisRow, sheet)
If note = "" Then note = check_length(thisRow, sheet)
If note = "" Then note = check_tolerance_enabled(thisRow, sheet)
If note = "" Then note = check_tolerance(thisRow, sheet)
End If
' Set note string (done outside the if blank lines checker so that it will reset the note to nothing on blank lines)
' only change it actually set it if it has changed (optimization)
If Not .Range(COL_NOTE & thisRow).value = note Then
.Range(COL_NOTE & thisRow).value = note
End If
End With
End Sub
Validators for individual columns
These functions takes a row and validate the a certain column according to it's special requirements. Returns a string if the validation fails.
' Makes sure that type is :
' Unique in its column
' Not empty
Function check_type(affectedRow As Long, sheet As Worksheet) As String
Dim value As String
Dim duplicate_found As Boolean
Dim lastRow As Long
Dim i As Long
duplicate_found = False
value = sheet.Range(COL_TYPE & affectedRow).value
check_type = ""
' Empty value check
If value = "" Then
check_type = "Type is missing"
Else
' Check for uniqueness
lastRow = sheet.Range(COL_TYPE & sheet.Rows.count).End(xlUp).row
If lastRow > ROW_FIRST Then
For i = ROW_FIRST To lastRow
If Not i = affectedRow And sheet.Range(COL_TYPE & i).value = value Then
duplicate_found = True
End If
Next
End If
If duplicate_found Then
check_type = "Type has to be unique"
Else
' OK
End If
End If
End Function
' Makes sure that length is a whole number larger than -1
Function check_length(affectedRow As Long, sheet As Worksheet) As String
Dim value As String
value = sheet.Range(COL_LENGTH & affectedRow).value
check_length = ""
If value = "" Then
check_length = "Length is missing"
ElseIf IsNumeric(value) Then
If Not Int(value) = value Then
check_length = "Length cannot be decimal"
ElseIf value < 0 Then
check_length = "Length is below 0"
ElseIf InStr(1, value, ".") > 0 Then
check_length = "Length contains a dot"
Else
' OK
End If
ElseIf Not IsNumeric(value) Then
check_length = "Length is not a number"
End If
End Function
' Makes sure that tolerance enabled is either 1 or 0:
Function check_tolerance_enabled(affectedRow As Long, sheet As Worksheet) As String
Dim value As String
value = sheet.Range(COL_TOLERANCE_ENABLED & affectedRow).value
check_tolerance_enabled = ""
If Not value = "0" And Not value = "1" Then
check_tolerance_enabled = "Tolerance enabled has to be 1 or 0"
Else
' OK
End If
End Function
' Makes sure that tolerance is a whole number larger than -1
' But only checks tolerance if it is enabled in the tolerance enabled column
Function check_tolerance(affectedRow As Long, sheet As Worksheet) As String
Dim value As String
value = sheet.Range(COL_TOLERANCE & affectedRow).value
check_tolerance = ""
If value = "" Then
If sheet.Range(COL_TOLERANCE_ENABLED & affectedRow).value = 1 Then
check_tolerance = "Tolerance is missing"
End If
ElseIf IsNumeric(value) Then
If Not Int(value) = value Then
check_tolerance = "Tolerance cannot be decimal"
ElseIf value < 0 Then
check_tolerance = "Tolerance is below 0"
ElseIf InStr(1, value, ".") > 0 Then
check_tolerance = "Tolerance contains a dot"
Else
' OK
End If
ElseIf Not IsNumeric(value) Then
check_tolerance = "Tolerance is not a number"
End If
End Function
Addressing support functions
These functions translates a letter to a column and vice versa.
Function let2Col(colStr As String) As Long
let2Col = Range(colStr & 1).Column
End Function
Function col2Let(iCol As Long) As String
Dim iAlpha As Long
Dim iRemainder As Long
iAlpha = Int(iCol / 27)
iRemainder = iCol - (iAlpha * 26)
If iAlpha > 0 Then
col2Let = Chr(iAlpha + 64)
End If
If iRemainder > 0 Then
col2Let = col2Let & Chr(iRemainder + 64)
End If
End Function
Code is tested on/has to work for Excel 2010 and onwards.
Edited for clarity
Finally got it working
After quite a bit of more agonizing, it turned out the fix was quite easy.
I added a new test that checks if the area that the user changed (the Target Range) consists of a column by looking at the address of the Range, if it is a full column the checker will ignore it. This solves the problem where the validation hogs Excel for about one minute.
The result of the intersection calculation is used for the inner loop which limits checks to cells within the area we are interested in validating.
Fixed Worksheet_Change function
Option Explicit
' Run every time something is changed in the User Input sheet
Private Sub Worksheet_Change(ByVal Target As Range)
Dim InterestingRange As Range
Set InterestingRange = Intersect(Target, Me.Range(COL_TYPE & ":" & COL_TOLERANCE))
If Not InterestingRange Is Nothing Then
' Guard against validating every cell in an inserted column
If Not RangeAddressRepresentsColumn(InterestingRange.address) Then
Dim myCell As Range
' This loop makes it work if multiple cells are changed,
' for example when pasting cells
For Each myCell In InterestingRange.Cells
' Protect the header rows
If myCell.row >= ROW_FIRST Then
checkInput_cell myCell.row, myCell.Column, Me
End If
Next
End If
End If
End Sub
New support function
' Takes an address string as input and determines if it represents a full column
' A full column is on the form $A:$A for single or $A:$C for multiple columns
' The unique characteristic of a column address is that it has always two
' dollar signs and one colon
Public Function RangeAddressRepresentsColumn(address As String) As Integer
Dim dollarSignCount As Integer
Dim hasColon As Boolean
Dim Counter As Integer
hasColon = False
dollarSignCount = 0
' Loop through each character in the string
For Counter = 1 To Len(address)
If Mid(address, Counter, 1) = "$" Then
dollarSignCount = dollarSignCount + 1
ElseIf Mid(address, Counter, 1) = ":" Then
hasColon = True
End If
Next
If hasColon And dollarSignCount = 2 Then
RangeAddressRepresentsColumn = True
Else
RangeAddressRepresentsColumn = False
End If
End Function

How do I use a string as a variable in vba?

This is what my cells look like:
This is my code, I'll explain it below.
Sub Macro1()
Dim product as String
Dim group as Long
Dim recordno as Long
dim pol_number as Long
dim plan_name as Long
product = "corp"
group = 1
recordno = 1
pol_number = 1
plan_name = "TTT"
Range("A2").Select
For i = 1 to 5
ActiveCell.Value = Selection.End(xlUp).Value
ActiveCell.Offset(0,1).Select
Next i
End Sub
I want to fill in all of the cells with the variable values. I understand that variables are not case sensitive, and I understand that the code I have will just fill the cell with the text in the upmost cell of the column, but I don't know if there is a function that would take the text of the top cell and convert it to a variable. Is that possible?
Try this to go from variables to cells
Dim values as Variant
'Array 0 to 4
values = Array(product,group,recordno,pol_number,plan_name)
Range("A2").Resize(1,5).Value2 = values
The reverse is
Dim values as Variant
'Array 1 to 5
values = Range("A2").Resize(1,5).Value2
product = values(1,1)
group = values(1,2)
recordno = values(1,3)
pol_number = values(1,4)
plan_name = values(1,5)
If you do something like
someCell.Value = someOtherCell.Value
and someOtherCell.Value is "product" then someCell won't be filled with what you have saved in the variable product but with "product" (I included the quotation marks to emphasize that's it's a string). That's a good thing because otherwise it would mess your code up if you accidentally put in the name of some random variable in your code.
If your requirements are like this:
You have values for PRODUCT etc that you write to write in the row below PRODUCT etc.
The headers are not always in the same order.
You might want to add new variables later on without too much fuss.
Them some kind of keyed list might be what your looking for. That means that rather than referencing the variable by a numerical index, you can reference them using names.
If the order is fixed, you might be better of just using an array where item 1 is the product name, item 2 is the group number etc, like ja72 and Sgdva suggested.
However, if you still want to reference the variables by name, you could use a collection:
Dim coll As New Collection
With coll
.Add "corp", "product"
.Add 1, "group"
.Add 1, "recordno"
'...
End With
Then instead of selecting cells and referencing ActiveCell you should reference the cells directly (using selections and ActiveCell can be avoided most of the times and slows down the macro and can even cause unnecessary errors)
For i = 1 To 5
Cells(2, i).value = coll(Cells(1, i).value)
Next i
An alternative to a collection is a dictionary which offers an easy way to check if a key exists (with a collection you have to catch the error)
Dim dict As Object
Set dict = CreateObject("Scripting.Dictionary")
With dict
.Add "product", "corp"
.Add "group", 1
.Add "recordno", 1
'...
End With
Now you can check if the entry exists first so it won't throw an error:
For i = 1 To 5
If dict.Exists(LCase(Cells(1, i).value)) Then 'note that the dictionary keys are case sensitive
Cells(2, i).value = dict(LCase(Cells(1, i).value))
Else
MsgBox "Entry for " & LCase(Cells(1, i).value) & " not found!"
End If
Next i
Note that when you use dict("somekey") and the entry "somekey" doesn't exist, it won't throw an error but add an empty entry.
Why not an array and then loop through the elements as needed?
Dim ArrayTitles() As Variant 'since strings and numbers are mixed
ReDim Preserve ArrayTitles(5)
ArrayTitles(1) = "corp"
ArrayTitles(2) = 1
ArrayTitles(3) = 1
ArrayTitles(4) = 1
ArrayTitles(5) = "TTT"
Range("A2").Select
For i = 1 To 5
MsgBox (ArrayTitles(i))
I'm thinking what you are trying to accomplish can be solved in this way
for j = 1 to 6 'Or whatever your last column happens to be
if UCase(cells(1, j)) = "PRODUCT" then
if ActiveCell.Column = j then
ActiveCell.Value = "corp"
end if
end if
next j
Something like that?

Excel VBA: If A2="a","b","c",etc... then B2="aa"?

I'm attempting to take the text in each cell of column A and assign a value to each cell in column B depending on the text in column A. For example, I have a list of versions that are identified by four-letter abbreviations of cities, and all of those versions are regionally assigned to different factories to be produced. So let's say I have an "AUST", "DAFW", "HOUS", and more versions all assigned to the location of "ARLINGTON". How would I most concisely use VBA to automate that once I have all the versions plugged in? Something like
If A2="AUST" Then
B2="ARLINGTON"
ElseIf A2="DAFW" Then
B2="ARLINGTON"
I suppose something like this would work, however I can't believe that there's not a faster and more concise way. Does this make any sense? I've been pulling my hair out for about a week now trying to figure this out... Thanks for any help!
This is a little simpler using OR:
If A2="AUST" OR A2="DAFW" Then
B2="ARLINGTON"
ElseIf A2 = "ABCD" OR A2 = "WZYZ" Then
B2="SOMETHING"
'ETC...
However, if you are iterating over column A, the variable "A2" is strange. But I am not sure how you are doing this. Maybe supply more code and we can help you more.
This could be done with excel formulas as well, though I always prefer to use VBA. This should work the way you want :
Sub yourFunk()
Set wb = ThisWorkbook
Set ws = wb.Sheets(1)
arlington = Array("AUST", "DAFW", "HOUS")
otherLocation = Array("XXXX", "YYYY", "ZZZZ")
lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
For x = 2 To lastRow
If stringIsInArray(ws.Cells(x, 1), arlington) Then
ws.Cells(x, 2) = "ARLINGTON"
ElseIf stringIsInArray(ws.Cells(x, 1), otherLocation) Then
ws.Cells(x, 2) = "OTHER LOCATION"
End If
Next x
End Sub
Function stringIsInArray(stringToBeFound As String, arr As Variant) As Boolean
stringIsInArray = (UBound(Filter(arr, stringToBeFound)) > -1)
End Function
If you need me to explain the code, please do let me know :)
The fastest way is to use Dictionary.
Let's say, your data is present in the following range:
A2 = "AUST"
A3 = "DAFW"
Now, check this code:
'Needs reference to Microsoft Scripting Runtime
Sub Translate()
Dim dic As Dictionary
Dim i As Integer, sTmp As String
Set dic = New Dictionary
dic.Add "AUST", "ARLINGTON"
dic.Add "DAFW", "ARLINGTON"
For i = 2 To 3
sTmp = ThisWorkbook.Worksheets(1).Range("A" & i)
Debug.Print sTmp, "-", dic(sTmp)
Next
Set dic = Nothing
End Sub
Note: This code is just an example!

Copy unique records from one workbook to another master workbook

I need some help with copying unique records from one workbook to a master workbook please.
Each month I receive a new workbook with data and I want to be able to copy all new records in that new workbook to one master workbook which will have all the amalgamted records. There is one unique reference field which can be used for the lookup to identify a new record.
In addition to this what I want to do is update values which are in 3 columns for ALL existing records on the master workbook which might be on the new workbook.
Example
Master workbook
Ref Name Value 1 Value 2 Value 3 Description
123 TR 100 50 200 xxxxxxxxxxxxxxx
111 WE 90 45 400 xxxxxxxxxxxxxxx
New workbook
Ref Name Value 1 Value 2 Value 3 Description
123 TR 300 200 200 xxxxxxxxxxxxxxx
456 MA 100 500 700 xxxxxxxxxxxxxxx
Update master workbook
Ref Name Value 1 Value 2 Value 3 Description
123 TR 300 200 200 xxxxxxxxxxxxxxx
111 WE 90 45 400 xxxxxxxxxxxxxxx
456 MA 100 500 700 xxxxxxxxxxxxxxx
I'd appreciate any help with this please. Thanks
I wrote a small module that does what you want (and even more). I tried to make it as generic as possible, but I had to assert a few things and limit it somehow - otherwise it would get quickly out of hand (as I think it already did.. kind of).
The limitations/assertions are the following:
1. the records are considered to be laid out only in rows (as per your example).
2. there is no column checking during the update or insertion of values. The program assumes that both master and new workbooks contain the same columns and laid in the exact same order.
3. There is no validation check for duplicate reference values. The "ref" column that you indicate as your primary key in each data range, is assumed to contain unique values (for that data range).
Apart from those assumptions, my solution is enhanced with flexible arguments (optional or autoconfigurable - see how dataRange is determined) to allow for several types of operation.
optional colorAlertOption flag: allows updated or inserted entries to be colored in order to be more distinguisable (true by default)
optional rangeWithHeaders flag: helps to determine if the supplied dataRange argument needs to be resized (remove headers) or not (true by default)
optional refColIndex integer: the relative to the dataRange - not the whole worksheet - column number pinpointing the column containing the unique references. (1 by default)
required dataRangeNew, dataRangeMaster (Range) arguments: flexible representations of the data-ranges for the new and master datasets respectively. You can either provide them explicitly (e.g. "$A$1:$D$10") or by giving only a single cell contained anywhere within the data-range. The only predicates are that the data-range should be isolated from other possible data coexisting on the same sheet (by means of blank rows or columns) and that it contains at least 1 row.
You can call the updateMasterDataRange procedure like this:
call updateMasterDataRange (Workbooks(2).Sheets("new").Range("a1"), Workbooks(1).Worksheets("master").Range("a1"))
Notice the fully qualified data ranges, including the workbooks and the worksheets in the mix. If you don't prepend these identifiers, VBA will try to associate the unqualified Range with ActiveWorkbook or/and ActiveWorksheet, with unpredictable results.
Here goes the body of the module:
Option Explicit
Option Base 1

ByRef dataRangeNew As Range, ByRef dataRangeMaster As Range, _
Optional refColIndexNew As Integer = 1, Optional refColIndexMaster As Integer = 1, _

The results of a simple execution on your example gave the expected results, as you can see in the attached picture. There is even a dialogue with a brief report on the accomplished operations.
You haven't got much of a start. Will this outline get you started?
open all 3 workbooks
for masterrow = beginrow to endrow
if match in newsheet then
updaterow = newrow
else
updaterow = masterrow
end if
next masterrow
' now pick up unmatched newrows
for newrow = beginrow to endrow
if not match in updatesheet then
updaterow = newrow
end if
next newrow
EDIT: CodeVortex did the whole thing. My outline was flawed.
open both workbooks
appendrow = endrow of mastersheet
for newrow = beginrow to endrow
if match in mastersheet then
update masterrow
else
append into appendrow
appendrow = appendrow + 1
end if
next newrow

VBA code to hide a number of fixed discrete rows across a few worksheets

I'm for a solution to part of a macro I'm writing that will hide certain (fixed position) rows across a few different sheets. I currently have:
Sheets(Sheet1).Range("5:20").EntireRow.Hidden = True
To hide rows 5-20 in Sheet1. I also would like to hide (for arguements sake), row 6, row 21, and rows 35-38 in Sheet2 - I could do this by repeating the above line of code 3 more times; but am sure there's a better way of doing this, just as a learning exercise.
Any help much appreciated :)

Specify a Union of some ranges as follows
With Sheet1
Union(.Range("1:5"), .Rows(7), .Range("A10"), .Cells(12, 1)).EntireRow.Hidden = True
End With
Here is a try:
Sub hideMultiple()
Dim r As Range
Set r = Union(Range("A1"), Range("A3"))
r.EntireRow.Hidden = True
End Sub
But you cannot Union range from several worksheets, so you would have to loop over each worksheet argument.
This is a crude solution: no validation, no unhiding of existing hidden rows, no check that I have a sheet name as first parameter, etc. But it demonstrates a technique that I often find useful.
I load an array with a string of parameters relevant to my current problem and code a simple loop to implement them. Look up the sub and function declarations and read the section on ParamArrays for a variation on this approach.
Option Explicit
Sub HideColumns()
Dim InxPL As Integer
Dim ParamCrnt As String
Dim ParamList() As Variant
Dim SheetNameCrnt As String
ParamList = Array("Sheet1", 1, "5:6", "Sheet2", 9, "27:35")
SheetNameCrnt = ""
For InxPL = LBound(ParamList) To UBound(ParamList)
ParamCrnt = ParamList(InxPL)
If InStr(ParamCrnt, ":") <> 0 Then
' Row range
Sheets(SheetNameCrnt).Range(ParamCrnt).EntireRow.Hidden = True
ElseIf IsNumeric(ParamCrnt) Then
' Single Row
Sheets(SheetNameCrnt).Range(ParamCrnt & ":" & _
ParamCrnt).EntireRow.Hidden = True
Else
' Assume Sheet name
SheetNameCrnt = ParamCrnt
End If
Next
End Sub
