If Then to Loop through Pivot Items - vba

I'm stuck on this issue and cannot figure out what it is I am doing wrong. I'm in the process of writing a macro to loop through visible fields in a pivot table, find the items in those fields that are filtered, and then apply those filters to the source data table. The particular problem I'm having deals with a loop that is supposed to look in a field, find the visible pivot items, and then store those items as variables. I've been messing around with trying to terminate the loop if all pivot items are visible. Below is what I have so far:
Sub PivotTest2()
Dim pi As PivotItem
Dim count As Integer
Dim available As Integer
Dim row As Integer
available = ActiveSheet.PivotTables("Cities").PivotFields("City").PivotItems.count
row = 2 'This is your starting row for display
For Each pi In ActiveSheet.PivotTables("Cities").PivotFields("City").PivotItems
If pi.Visible Then
count = count + 1
End If
If count = available Then
MsgBox ("All Pivot Items Are Selected")
End If
If count <> available Then
row = row + 1
Range("'Sheet4'!G" & row) = pi.Name
End If
Next pi
End Sub
So whenever I have a filter on a city, or group of cities, the macro pastes them to a range in the spreadsheet. Eventually, I want to store them as variables, but for now I'm just pasting them for the purposes of working through the code. You can also see that when the number of visible items is equal to the total number of pivot items in that field, I'm returning a message box. Eventually, that message box will go away and be replaced by code that tells it to start looking through pivot items in the next visible field.
I realize that this might be unnecessary, as applying all visible items as filters to the source data field would result in all items being shown, which accomplishes the same thing. However, I'm more curious about what it is I'm doing wrong at this point. The code pastes all items to the range, regardless of whether there is a filter or not. However, the message box only returns when there is no filter applied, so it appears to be working correctly.
Any input/feedback would be appreciated. Thanks.

It seems that part of your checks should be outside your loop which determines the amount of visible PivotItems.
At first, I'd suggest to move the Next pi after the first If-End If block. Your count variable should then contain the number of visible items. If all items are visible, your message box should then appear. However, for the second part (copying visible items), you'd need to loop again.
To avoid the second loop, you may want to copy the pi.Name values to a temporary range, and copy this range to the final range only if there are filters applied.

Try this:
For Each pi In ActiveSheet.PivotTables("Cities").PivotFields("City").PivotItems
If pi.Visible Then
count = count + 1
Range("'Sheet4'!G" & row) = pi.Name
row = row + 1
End If
Next pi
If count = available Then
MsgBox ("All Pivot Items Are Selected")
End If
Your code doesn't check if the city is visible before pasting, which is why it always pastes every city name.

Data Validation of a Filtered table

I have a Data table with an Auto Filter (shown Below).
Sub Tariff_Filter()
Dim columnNumber, tableRow, tableColumn, tableWidth As Integer
Dim tableName, columnName As String
tableName = "Tariff_Table"
columnName = ActiveSheet.Range("A1").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
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 & "Please Specify Required Channel"
End Sub
As i cant seem to figure out how to get my combo-box's to show only the visible cells after filtering the table i was wondering if there is a way i can create a a validation box to show the visible cells or copy the visible data into a seperate table underneath. I can then use the validation box/ secondary table as a focus point for the combo-box's on the user-form.
Thanks in advance
If I'm understanding your question correctly, you would like to have a data-validation drop-down list that updates as the table is filtered and only displays visible items for a given column.
You can do this by using the following formula in Data Validation (I'm assuming your table header row starts in A1 and it's col A you need to display):
=OFFSET($A$2,,,SUBTOTAL(103,TableName[column name]))
This formula expands from the starting cell (A2) by a specified height in number of rows. We are defining the height using SUBTOTAL with function number 103 - this means that the height is defined using COUNTA, but only on visible cells, so it will expand and collapse as the table is filtered.
Be aware: since the height is defined using a counta function, it will only count cells containing data, therefore if you have blanks in your table, the range will not be defined correctly. Also if you have any repeated data, these will be repeated in your drop-down box, this method will not condense them into a neat, unique list.
Hope this is helpful.

Creating an Excel Macro to delete rows if a column value repeats consecutively less than 3 times

The data I have can be simplified to this:
http://i.imgur.com/mn5GgrQ.png
In this example, I would like to delete the data associated with track 2, since it has only 3 frames associated with it. All data with more than 3 associated frames can stay.
The frame number does not always start from 1, as I've tried to demonstrate. The track number will always be the same number consecutively for as many frames as are tracked. I was thinking of using a function to append 1 to a variable for every consecutive value in column A, then performing a test to see if this value is equal >= 3. If so, then go onto the next integer in A, if no, then delete all rows marked with that integer (2, in this case).
Is this possible with Visual Basic in an Excel Macro, and can anyone give me some starting tips on what functions I might be able to use? Complete novice here. I haven't found anything similar for VBA, only for R.
I assume you understand the code by reading it.
Option Explicit
Public Function GetCountOfRowsForEachTrack(ByVal sourceColumn As Range) As _
Scripting.Dictionary
Dim cell As Range
Dim trackValue As String
Dim groupedData As Scripting.Dictionary
Set groupedData = New Scripting.Dictionary
For Each cell In sourceColumn
trackValue = cell.Value
If groupedData.Exists(trackValue) Then
groupedData(trackValue) = cell.Address(False, False) + "," + groupedData(trackValue)
Else
groupedData(trackValue) = cell.Address(False, False)
End If
Next
Set GetCountOfRowsForEachTrack = groupedData
End Function
Public Sub DeleteRowsWhereTrackLTE3()
Dim groupedData As Scripting.Dictionary
Set groupedData = GetCountOfRowsForEachTrack(Range("A2:A15"))
Dim cellsToBeDeleted As String
Dim item
For Each item In groupedData.Items
If UBound(Split(item, ",")) <= 2 Then
cellsToBeDeleted = item + IIf(cellsToBeDeleted <> "", "," + cellsToBeDeleted, "")
End If
Next
Range(cellsToBeDeleted).EntireRow.Delete
End Sub
GetCountOfRowsForEachTrack is a function returning a dictionary (which stores track number as key, cell address associated with that track as string)
DeleteRowsWhereTrackLTE3 is the procedure which uses GetCountOfRowsForEachTrack to get the aggregated info of Track numbers and cells associated with it. This method loops through the dictionary and checks if the number of cells associated with track is <=2 (because splitting the string returns an array which starts from 0). It builds a string of address of such cells and deletes it all at once towards the end.
Note:
Add the following code in a bas module (or a specific sheet where
you have the data).
Add reference to "Microsoft Scripting.Runtime" library. Inside VBA, click on "Tools" -> "References" menu. Tick the "Microsoft Scripting.Runtime" and click on OK.
I have used A2:A15 as an example. Please modify it as per your cell range.
The assumption is that you don't have thousands of cells to be deleted, in which case the method could fail.
Make a call to DeleteRowsWhereTrackLTE3 to remove such rows.

VBA Macro: Trying to code "if two cells are the same, then nothing, else shift rows down"

My Goal: To get all data about the same subject from multiple reports (already in the same spreadsheet) in the same row.
Rambling Backstory: Every month I get a new datadump Excel spreadsheet with several reports of variable lengths side-by-side (across columns). Most of these reports have overlapping subjects, but not entirely. Fortunately, when they are talking about the same subject, it is noted by a number. This number tag is always the first column at the beginning of each report. However, because of the variable lengths of reports, the same subjects are not in the same rows. The columns with the numbers never shift (report1's numbers are always column A, report2's are always column G, etc) and numbers are always in ascending order.
My Goal Solution: Since the columns with the ascending numbers do not change, I've been trying to write VBA code for a Macro that compares (for example) the number of the active datarow with from column A with Column G. If the number is the same, do nothing, else move all the data in that row (and under it) from columns G:J down a line. Then move on to the next datarow.
I've tried: I've written several "For Each"s and a few loops with DataRow + 1 to and calling what I thought would make the comparisons, but they've all failed miserably. I can't tell if I'm just getting the syntax wrong or its a faulty concept. Also, none of my searches have turned up this problem or even parts of it I can maraud and cobble together. Although that may be more of a reflection of my googling skill :)
Any and all help would be appreciated!
Note: In case it's important, the columns have headers. I've just been using DataRow = Found.Row + 1 to circumvent. Additionally, I'm very new at this and self-taught, so please feel free to explain in great detail
I think I understand your objective and this should work. It doesn't use any of the methodology you were using as reading your explanation I had a good idea how to proceed. If it isn't what you are looking for my apologies.
It starts at a predefined column (see FIRST_ROW constant) and goes row by row comparing the two cells (MAIN_COLUMN & CHILD_COLUMN). If MAIN_COLUMN < CHILD_COLUMN it pushes everything between SHIFT_START & SHIFT_END down one row. It continues until it hits an empty row.
Sub AlignData()
Const FIRST_ROW As Long = 2 ' So you can skip a header row, or multiple rows
Const MAIN_COLUMN As Long = 1 ' this is your primary ID field
Const CHILD_COLUMN As Long = 7 ' this is your alternate ID field (the one we want to push down)
Const SHIFT_START As String = "G" ' the first column to push
Const SHIFT_END As String = "O" ' the last column to push
Dim row As Long
row = FIRST_ROW
Dim xs As Worksheet
Set xs = ActiveSheet
Dim im_done As Boolean
im_done = False
Do Until im_done
If WorksheetFunction.CountA(xs.Rows(row)) = 0 Then
im_done = True
Else
If xs.Cells(row, MAIN_COLUMN).Value < xs.Cells(row, CHILD_COLUMN).Value Then
xs.Range(Cells(row, SHIFT_START), Cells(row, SHIFT_END)).Insert Shift:=xlDown
Debug.Print "Pushed row: " & row & " down!"
End If
row = row + 1
End If
Loop
End Sub
I modified the code to work as a macro. You should be able to create it right from the macro dialog and run it from there also. Just paste the code right in and make sure the Sub and End Sub lines don't get duplicated. It no longer accepts a worksheet name but instead runs against the currently active worksheet.

Is there a way to check for duplicate values in Excel WITHOUT using the CountIf function?

A lot of the solutions here on SO involve using CountIf to find duplicates. When I have a list of 100,000+ values however, it will often take minutes for CountIf to search for duplicates.
Is there a quicker way to search for duplicates within an Excel column WITHOUT using CountIf?
Thanks!
EDIT #1:
After reading the comments and replies I realize I need to go into greater detail. Let's pretend I'm a birdwatcher, and after I return from a birdwatching trip I input anywhere from 1 to 25 or 50 new birds that I saw on my trip into my "Master List of Birds Seen". This is really a dynamically growing list, and with each addition I want to make sure I'm not duplicating something that already exists in my list.
So, in column A of my file are the names of the birds. Column B-M might contain other attributes of the birds. I want to know if a bird that I just added in column A after my latest birdwatching trip ALREADY exists somewhere ELSE in my list. And, if it does, I would manually merge the data of the 2 entries and throw away some and keep some after careful review. I clearly don't want to have duplicate entries of the same bird in my database.
So, ultimately I want some indication that there is or isn't a duplicate somewhere else, and if there is duplicate please tell me what row to look in (or highlight or color both of the duplicates).
The fastest way that I know of (in case you are using Excel 2007/2010/2011) is to use Data (In Ribbon) | Remove Duplicates to find the total number of duplicates OR to remove duplicates. You might want to move data to a temp sheet before you test this.
The 2nd fastest way is to use Countif. Now Countif can be used in many ways to find duplicates. Here are two main ways.
1) Inserting a New Column next to the data and putting the formula and simply copying it down.
2) Using Countif in Conditional formatting to highlight cells which are duplicates. For more details, please see this link.
suggestions for a macro to find duplicates in a SINGLE column
EDIT:
My Apologies :)
Countif is the 3rd fastest way!
The 2nd fastest way is to use Pivot Tables ;)
What exactly is your main purpose of finding duplicates? Do you want to delete them? Or Do you want to highlight them? Or something else?
FOLLOWUP
Seems like I made a typo in the formula. Yes for large number of rows, CountIf does take minutes as you suggested.
Let me see if I can come up with a VBA code to suit your exact needs.

You can use VBA - the following function returns a list of unique entries within a list of 100,000 in less than a second. Usage: select a range, type the formula (=getUniqueListFromRange(YourRange)) and validate with CTRL+SHIFT+ENTER.
Public Function getUniqueListFromRange(parRange As Range) As Variant
' Returns a (1 to n,1 to 1) array with all the values without duplicates
Dim i As Long
Dim j As Long
Dim locKey As Variant
Dim locData As Variant
Dim locUniqueDict As Variant
Dim locUniqueList As Variant
On Error GoTo error_handler
locData = Intersect(parRange.Parent.UsedRange, parRange)
Set locUniqueDict = CreateObject("Scripting.Dictionary")
On Error Resume Next
For i = 1 To UBound(locData, 1)
For j = 1 To UBound(locData, 2)
locKey = UCase(locData(i, j))
If locKey <> "" Then locUniqueDict.Add locKey, locData(i, j)
Next j
Next i
If locUniqueDict.Count > 0 Then
ReDim locUniqueList(1 To locUniqueDict.Count, 1 To 1) As Variant
i = 1
For Each locKey In locUniqueDict
locUniqueList(i, 1) = locUniqueDict(locKey)
i = i + 1
Next
getUniqueListFromRange = locUniqueList
End If
error_handler: 'Empty range
End Function
If using Excel 2007 or later (which is likely from the 100,000+ values) you can choose:
Home Tab | Conditional Formatting > Highlight Cell Rules > Duplicate Values...
Right-click a highlighted cell and filter by selected cell color to show just the duplicates (be aware however this can be slow with conditional formatting).
Alternatively run this code and filter for colored cells which takes only a second on 100,000 cells:
Sub HighlightDupes()
Dim i As Long, dic As Variant, v As Variant
Application.ScreenUpdating = False
Set dic = CreateObject("Scripting.Dictionary")
i = 1
For Each v In Selection.Value2
If dic.exists(v) Then dic(v) = "" Else dic.Add v, i
i = i + 1
Next v
Selection.Font.Color = 255
For Each v In dic
If dic(v) <> "" Then Selection(dic(v)).Font.Color = 0
Next v
End Sub
Addendum:
To select only duplicate values without code or formulas, i have found this method useful:
Data Tab | Advanced Filter... Filter in Place, Unique Records Only, OK.
Now select the range of unique values and press Alt+; (Goto Special... Visible cells only). With this selection clear the filter and you will see that all unselected cells are duplicates, you can then press Ctrl+9 (Hide Rows) to show just the duplicates. These rows can be copied to another sheet if needed or marked with an "X".
You do not mention what you want to do when you find them. If you merely want to see where they are...
Sub HighLightCells()
ActiveSheet.UsedRange.Cells.FormatConditions.Delete
ActiveSheet.UsedRange.Cells.FormatConditions.Add Type:=xlCellValue, Operator:=xlEqual, Formula1:=ActiveCell
ActiveSheet.UsedRange.Cells.FormatConditions(1).Interior.ColorIndex = 4
End Sub
Preventing Duplicates with Data Validation
You can use Data Validation to prevent you entering duplicate bird names. See Debra Dalgelish's site here
Handling existing duplicates
My free Duplicate Master addin will let you
Select
Colour
List
Delete
duplicates.
But more importantly it will let you run more complex matching than exact strings, ie
Case Insensitive / Case Sensitive searches (sample below)
Trim/Clean data
Remove all blank spaces (including CHAR(160)) see the " mapgie" and "magpie" example below
Run regular expression matches (for example the sample below replaces s$ with "" to remove plurals)
Match on any combination of columns (ie Column A, all columns, Column A&B etc)
I'm surprised that no one has mentioned the RemoveDuplicates method.
ActiveSheet.Range("A:A").RemoveDuplicates Columns:=1
This will simply remove any duplicate entries on the active worksheet in column A. It takes milliseconds to run (tested with 200k rows). Mind you, this will strictly delete all the duplicate entries. Although that isn't how the original question was worded, I do believe that this still serves your purpose.
One simple way of finding unique values is to use the advance filter and filter for unique values only and copy and paste them into other sheet as when the pivot is removed you will get the whole data with the duplicate in them.
Sort the range
and in next column put `=if(a2=a1;1;if(a2=a3;1;0))
"1" will be displayed for duplicates.

How to find the number of expanded/collapsed master rows and grouped rows in a DevExpress GridView?

I am currently using DevExpress 10.2 within Visual Studio 2010. In a previous question I was trying to print the current user view of a DevExpress GridControl with the user's choice of expanded or collapsed master rows and/or group sections. I was told this was not possible at this time. I have now decided to use the following code:
gvPOinvoiceBanded.OptionsPrint.ExpandAllGroups = False
gvPOinvoiceBanded.OptionsPrint.ExpandAllDetails = False
when I want it to be completely collapsed while printing as by default these are set to true.
I was just wondering if there is someway to check either the total number of expanded master rows or the total number of collapsed master rows. I would also like to do the same thing for the groups as you can have the groups expanded while the master rows are not.
You can get the number of expanded group rows using a loop like this:
Dim ExpandedGroupCount As Integer = 0
Dim Handle As Integer = -1 'group rows have negative row handles
Do Until GridView1.GetRow(Handle) Is Nothing
If GridView1.GetRowExpanded(Handle) Then
ExpandedGroupCount += 1
End If
Handle -= 1
Loop
'Do whatever with expanded group count
MsgBox(String.Format("Number of Expanded Group Rows: {0}{2}Number of Group Rows: {1}",
ExpandedGroupCount, Math.Abs(Handle + 1), Environment.NewLine))
Similarly, you can do this to get the count of expanded master rows:
Handle = 0
Dim ExpandedMasterRowCount As Integer = 0
Do Until GridView1.GetRow(Handle) Is Nothing
If GridView1.IsMasterRow(Handle) Then
If GridView1.GetMasterRowExpanded(Handle) Then
ExpandedMasterRowCount += 1
End If
End If
Handle += 1
Loop
MsgBox(String.Format("Number of Expanded Master Rows: {0}", ExpandedMasterRowCount))
Of course, if you are only checking so that you can see if you need to set the collapse this probably isn't worth the effort. There is no direct property that provides the counts you are looking for.
You could also probably use the events that fire when rows are collapsed and expanded to track the count as it changes. You have to be careful with that though because the event only fires once when expand or collapse all happens. So if you go with that method be sure to check the rowHandle in the event arguments parameter for GridControl.InvalidRowHandle. That is the value used in the case of collapse or expand all.
