Using VBA to name ranges and create charts with those ranges - vba

I'm new to VBA. I'm attempting to create over 500 xlClusteredColumn charts using two columns of information and I'd like to expedite the work. The first column contains names I'd like to use for named ranges (i.e.: Line1, Line2, etc.) and the second column contains the indirect references of the data ranges (i.e., Sheet1!C4:D28, Sheet1!C28:D90). I noticed that if I use a named range for the "Chart Data Series" field, the data shows up nicely (but I have to first create that named range being sure to include the INDIRECT formula in the reference, (e.g.: Named Range Line1 is equal to =INDIRECT(Sheet1!C4:C28)). The ranges will be static.
In reviewing prior questions I couldn't seem to find a solution that would select the first cell in this set and name it, then uses the second cell to define that range. I think I might need the ActiveWorkbook.Names.Add Name:= formula and combine it with a loop (but I couldn't get it to use a selection or cell to define the Add Name aspect, only a hard coded name).
If the solution requires it, I can go back and extract the individual ranges (i.e.: C4:D28) from the cell and have the chart reference only that if it makes the code simpler. I know my first outlined attempt isn't the only solution and there's probably one much more elegant. I figured using named ranges would speed up the chart work, but perhaps there's a way to cut that step out?
Populating a new sheet with all the charts for each of these ranges would be icing on the cake, but I'll be happy enough receiving help to get the data set up to chart.
Example information:
NameRange1 (let's say in cells A1:A4)
WKD_1_NB
WKD_2_EB
WKD_3_EB
SerRange1 (in cells B1:B4)
WKDpivot!C4:D43
WKDpivot!C84:D140
WKDpivot!C197:D233
(Chart data range requires the reference of named range "WKD_1_NB" to be '=INDIRECT(WKDpivot!C4:D43)' in order for the chart to work.

OK so why don't you try the two-step process. I am going to do this without Indirect because I don't see that it is necessary.
Sub CreateNames()
Dim rng As Range
Dim r As Range
Dim myName As String
Dim addr As String
Set rng = Range("A1:A2") '## Modify as needed
For Each r In rng.Cells
myName = r.Value
addr = "=" & r.Offset(0, 1).Value
ThisWorkbook.Names.Add myName, addr
Next
End Sub
This creates your names (screenshot). Note there are some rules about naming conventions and allowable names, etc., the code above does not take any of these in to account.
From there it should be fairly simple to create a loop that adds your charts one by one, and assigns each named range to each chart.

Excel Selecting a Row

I am Trying to create a macro that will take the 1st Cell of a selection and merge it with the 6th Cell. I am getting error 400.
Sub SignPage()
Dim ws As Worksheet, BasePoint As Range, row As Long, singlecell As Long,
singleCol As Long, sLong As Long, sShort As String
Set BasePoint = Selection
row = BasePoint.row
Range(Cells(row, BasePoint.Columns(1)), Cells(row, BasePoint.Columns(6))).Merge
End Sub
This should be enough:
Selection(1).Resize(, 6).Merge
Explanation: Selection can span several cells, so Selection(1) takes the top left cell - thus, we always refer to one cell.
The point is that you should refer to the first column of Basepoint and take its column. This could be achieved, if you amend your line like to this:
Range(Cells(row,BasePoint.Columns(1).Column),Cells(row,BasePoint.Columns(6).Column)).Merge
As an advice:
do not use names like row, column, Cells, Range etc. as a variable, the Excel object module library inside VBA uses them as well. In your case, you have BasePoint.row. If you did not have the variable row, then the VBEditor would have written BasePoint.Row automatically.
try to avoid Selection, although it depends on the context - How to avoid using Select in Excel VBA
as #Mat's Mug mentioned in the comments, it is a good habit to show the "parent" of Cells and Ranges, when you are using them.
Thus in your case, something like this:
With Worksheets(1)
.Range(.Cells(row, BP.Columns(1).Column), .Cells(row, BP.Columns(6).Column)).Merge
End With
Then it would always refer to the first worksheet (or whichever you need to) and not to the ActiveSheet, which would be referred, if the Parent in not mentioned. (I have written BP instead of BasePoint to make sure it goes on one line.)

User Inserted Rows/Columns Impacting Excel VBA

I am trying to determine how I can have a user insert columns and/or rows without it impacting the rest of the code in the macro.
Defining names for my objects and using r1c1 references in VBA does not seem to help as these inserted columns shift those references and names as well.
Am I missing something that should be completely obvious???
Or is what I am trying to accomplish not possible?
UPDATE: When I name a range in excel (without VBA) everything seems to work fine with inserted columns. However, when I name the range with VBA everything messes up. Here is a sample of some code to work with.
When this below code is run... I am not able to insert columns as my MSGBOX's don't realize the named cell has shifted to the right. HOWEVER, if I were to remove the first line in this code and just name the cell "GanttStartLocation" which is quoted out in the code... this seems to work fine.
WHY DOES THiS NOT WORK WHEN NAMED WITH VBA????
ActiveWorkbook.Names.Add Name:="DEFINENAMETEST", RefersToR1C1:="=Sheet1!R10C14"
Dim rGanttLocation As Range 'Range used to define where the Gantt chart begins
Dim iFirstRowGantt As Integer 'Defines the first row of the Gantt chart based on rGanttLocation
Dim iFirstColumnGantt As Integer 'Defines the first column of the Gantt chart based on rGanttLocation
'Set rGanttLocation = Worksheets(1).Range("GanttStartLocation")
Set rGanttLocation = Worksheets(1).Range("DEFINENAMETEST")
iFirstRowGantt = rGanttLocation.Row
iFirstColumnGantt = rGanttLocation.Column
MsgBox (iFirstRowGantt)
MsgBox (iFirstColumnGantt)
Use a named range for your cells so that addition of rows/columns are less likely to impact your code if rows/columns are added inside the range. For example: if D1-F10 was called testrange, executing the following subroutine will give red background color to the range
Public Sub Test()
Range("testrange").Interior.Color = vbRed
End Sub
If a new row and column are added to this range, and the subroutine is re-executed after replacing vbRed with vbYellow, the entire range (with new column and row) will turn yellow.
Outside of the named range, it's going to take decent amount of work to keep your Macro's generic, from what I understand.

Excel VBA named range running out of space in refersto

So I have a large suite of code that creates an archive of data in sheets used by employees. Part of what makes this functional is named ranges on each sheet of usable data. In order for the data integrity to remain, I need to copy the named range objects from the archive sheet to its copy. The named ranges are built programatically and function as expected on the sheets. The problem I'm having is when I go to archive the sheet. Here is the code I'm using to handle the named range object:
For Each n In OldSht.Names
NamedRangeRefersTo = n.RefersTo
NamedRange = n.Name
TrimmedName = Right(n.Name, Len(n.Name) - InStr(1, n.Name, "!", vbTextCompare))
OldSht.Names(n.Name).Delete
OldSht.Names.Add Name:=ArchiveNamedRange, RefersTo:=NamedRangeRefersTo
Next n
The strings that grab data from n are used to add the same name object to the new sheet.
The problem I'm having is when a named range is referencing too large of a range when it hits the line Oldsht.Names.Add, it returns error 1004. I figured out it was the size of the referenced range by messing around with it. I haven't found the exact triggering cause, but this code works as-is when I use it on most of the named ranges. On large data sets with a joined data type that results in a very large named range (it would take a long time to explain how the ranges are built in text. It's a group of 8 sub functions with over 2000 lines of code), this results in the 1004 error.
What I'm confused by is why I can build the named range, use the named range, and copy the named range without issues (if I comment out the offending line, it executes perfectly but I lose data integrity). But when I take the referenced range into a code value, delete the old name reference, then add a new name(with a different name) and assign it the same refersto value of the old name, it can have this problem. I don't understand how it would be different doing this rather than just copying/renaming the name object. Unfortunately, I haven't found a workaround as of yet, nor have I found a clear cause of this error other than the fact that when I remove data or use smaller sets of data in test scenarios, I never have the problem. Does anyone have any ideas of what I can do? Does anyone have any ideas how a named range could be referring to a small enough range that it can be created, but using its refersto value to create a new named range could cause errors only when that is referencing a large range?
I wish I could provide some more concrete examples but unfortunately it would be very difficult to scrub enough sensitive info to provide the full code that would be necessary to reproduce my exact scenarios. Any ideas would be much appreciated.
As requested here's where ArchiveNamedRange gets set:
If Len(OldSht.Name) > 21 Then
ArchiveShtName = Left(OldSht.Name, 21) & DatePart("m", Date) & DatePart("d", Date) & DatePart("yyyy", Date)
Else
ArchiveShtName = OldSht.Name & DatePart("m", Date) & DatePart("d", Date) & DatePart("yyyy", Date)
End If
ArchiveNamedRange = ArchiveShtName & NameObjectName & "Test"
NameObjectName is just the name of the type of object and is passed in from another function. I'm not having an issue with the name just fyi. In the most extreme example the ArchiveNamedRange value at debug run time is = "OutageSystemProcedureMMDDYYYYSecurityRedactionTest" so the name might reach 50 and if things get crazier it might run upwards of 60 characters but it won't ever go beyond that or come anywhere near the 255 character limit. Ultimately, I haven't seen ArchiveNamedRange have an invalid value. It's just a string and it always has a value.
Edit-
Through my troubleshooting I've found that my code works when NamedRangeRefersTo has a length of 2075, but does not work when it has a length of 2091. So somewhere between 2075 characters and 2091 characters is a breaking point for assigning a string to RefersTo: in a named range.
So let's just assume there is a character limit for some reason of 2080 (or whatever it actually is between 2075 and 2091). When I initially find and create these named ranges, they are being given a range object. When I am copying the ranges I am copying as a string. Somehow when I pass a ranged object into RefersTo: it accepts characters beyond 2080 but when I pass in a string it does not. Given that this is my only breaking point of a large suite of code I'd rather find a workaround for this than have to re-factor the entire concept of my archive system. If I use a range object for copying the named ranges, their references follow the old Sheet. That means that when I copy the name over it can be "CriticalSystemsTest1" and referto: "CriticalSystemsTest1!$A$2,..." but once I copy that over and rename the archive worksheet (now CriticalSystems562015) the references adjust to be "CriticalSystems562015Test1!$A$2,..."
So I had to copy as a string to avoid that problem (it breaks data on the new sheet). All I really need is a creative way to overcome this character limit issue on my string. Rebuilding the named range from scratch on the new sheet is also not going to work. So I guess if anyone has ideas for how to work around this string size issue or a way of trimming the string while maintaining functionality of the named range, that would be amazing.
Each of these names has a worksheet level scope, so maybe if there's a way of using just the cell address($A$2) in RefersTo: so it doesn't also contain the worksheet reference (SheetName!), that would be a potential solution but I haven't figured out if that's even possible.
The reason the range definitions as strings are so long is that there are many areas within them. So one workaround would be to build up a new Range object area by area. You can use the string address of each area without running into any limits as each area only has a short reference. Using Range.Address gets the cell reference without the sheet reference, so you can create a new Range on a different sheet but with the same cells. Then use Union() to join all the areas and create the new name using the newly built Range instead of a string:
Dim i As Long, oldRange As Range, newRange As Range
Set oldRange = n.RefersToRange
Set newRange = oldSht.Range(oldRange.Areas(1).Address(External:=False))
For i = 2 To oldRange.Areas.Count
Set newRange = Union(newRange, oldSht.Range(oldRange.Areas(i).Address(External:=False)))
Next i
oldSht.Names.Add Name:="ArchiveNamedRange", RefersTo:=newRange
A couple of notes:
For ranges with many areas this is slow. If you can reliably tie down the threshold where you have problems, it would probably be worth testing for this first and only using this workaround where it was needed.
When testing I also ran into problems with using Worksheet.Range("some very long string range reference"), so this limitation isn't confined to named ranges.

in Excel use name from namebox ( range ? ) in VBA

What I want to do is select a range B2:B5and give it a name, just above cells A1 and B1 there is a namebox and I type the name: "My_Test_Range" here and hit enter.
The word Range is this the official name for range as described above in Excel?
Then I want to loop trough the range B2:B5 using VBA and do something like make all the cells to the right of the ranged cells 1.
How do I do the above?
I want to do this with the named range, because I find a name like "Options_For_Red_Car" or "Options_For_Blue_Car" much easier to read than B2:B5 etc., especially if you get say a dozen such ranges.
Range is a very important object in the Excel object model. Here is one of probably thousands of references to information about ranges:
http://msdn.microsoft.com/en-us/library/office/ff838238(v=office.15).aspx
Seems like you like named-ranges which is good as they are very powerful and useful and if you're going to start playing with vba then you'll find them more and more useful.
To loop through the cells in a range you can do something like the following:
Sub loopThroughRangeCells()
Dim cell
For Each cell In Excel.ThisWorkbook.Sheets("Sheet1").Range("A2:C6").Cells
MsgBox cell.Address
Next
End Sub
Although really it is better to create object reference variables when doing something like the above and also to use a `named-range':
Sub loopThroughRangeCells()
Dim cell
Dim s As Excel.Worksheet '<<creates an object variable
Set s = Excel.ThisWorkbook.Sheets("Sheet1") '<<the object variable now references our target sheet
'<<using object variable and named range the following code is simplified
For Each cell In s.Range("helloWorld").Cells
MsgBox cell.Address
Next
End Sub
In the above I've just done MsgBox cell.Address within the loop but you can change this to anything you like - you might like to experiment and try to change the cells to the right to 1.
In the above I've declared a variant typed variable cell. This is standard practice to call each member of the collection cells a cell even though no object cell exists in the object model. This is different than most collection like worksheets where it is a collection of an intuitive object worksheet

Why is my conditional format offset when added by VBA?

I was trying to add conditional formats like this:
If expression =($G5<>"") then make set interior green, use this for $A$5:$H$25.
Tried this, worked fine, as expected, then tried to adapt this as VBA-Code with following code, which is working, but not as expected:
With ActiveSheet.UsedRange.Offset(1)
.FormatConditions.Delete
'set used row range to green interior color, if "Erledigt Datum" is not empty
With .FormatConditions.Add(Type:=xlExpression, _
Formula1:="=($" & cstrDefaultProgressColumn & _
.row & "<>"""")")
.Interior.ColorIndex = 4
End With
End With
The Problem is, .row is providing the right row while in debug, however my added conditional-formula seems to be one or more rows off - depending on my solution for setting the row. So I am ending up with a conditional formatting, which has an offset to the row, which should have been formatted.
In the dialog it is then =($G6<>"") or G3 or G100310 or something like this. But not my desired G5.
Setting the row has to be dynamicall, because this is used to setup conditional formats on different worksheets, which can have their data starting at different rows.
I was suspecting my With arrangement, but it did not fix this problem.
edit: To be more specific, this is NOT a UsedRange problem, having the same trouble with this:
Dim rngData As Range
Set rngData = ActiveSheet.Range("A:H") 'ActiveSheet.UsedRange.Offset(1)
rngData.FormatConditions.Delete
With rngData.FormatConditions.Add(Type:=xlExpression, _
Formula1:="=($" & cstrDefaultProgressColumn & _
1 & "<>"""")")
.Interior.ColorIndex = 4
End With
My Data looks like this:
1 -> empty cells
2 -> empty cells
3 -> empty cells
4 -> TitleCols -> A;B;C;...;H
5 -> Data to TitleCols
. .
. .
. .
25
When I execute this edited code on Excel 2007 and lookup the formula in the conditional dialog it is =($G1048571<>"") - it should be =($G1<>""), then everything works fine.
Whats even more strange - this is an edited version of a fine working code, which used to add conditional formats for each row. But then I realized, that it's possible to write an expression, which formats a whole row or parts of it - thought this would be adapted in a minute, and now this ^^
edit: Additional task informations
I use conditional formatting here, because this functions shall setup a table to react on user input. So, if properly setup and a user edits some cell in my conditionalized column of this tabel, the corresponding row will turn green for the used range of rows.
Now, because there might be rows before the main header-row and there might be a various number of data-columns, and also the targeted column may change, I do of course use some specific informations.
To keep them minimal, I do use NamedRanges to determine the correct offset and to determine the correct DefaultProgessColumn.
GetTitleRow is used to determine the header-row by NamedRange or header-contents.
With ActiveSheet.UsedRange.Offset(GetTitleRow(ActiveSheet.UsedRange) - _
ActiveSheet.UsedRange.Rows(1).row + 1)
Corrected my Formula1, because I found the construct before not well formed.
Formula1:="=(" & Cells(.row, _
Range(strMatchCol1).Column).Address(RowAbsolute:=False) & _
"<>"""")"
strMatchCol1 - is the name of a range.
Got it, lol. Set the ActiveCell before doing the grunt work...
ActiveSheet.Range("A1").Activate
Excel is pulling its automagic range adjusting which is throwing off the formula when the FromatCondition is added.
The reason that Conditional Formatting and Data Validation exhibit this strange behavior is because the formulas they use are outside the normal calculation chain. They have to be so that you can refer to the active cell in the formula. If you're in G1, you can't type =G1="" because you'll create a circular reference. But in CF or DV, you can type that formula. Those formulas are disassociated with the current cell unlike real formulas.
When you enter a CF formula, it's always relative to the active cell. If, in CF, you make a formula
=ISBLANK($G2)
and you're in A5, Excel converts it to
=ISBLANK(R[-3]C7)
and when that gets put into the CF, it ends up being relative to the cell it's applied to. So in row 2, the formula comes out to
=ISBLANK($G655536)
(for Excel 2003). It offsets -3 rows and that wraps to the bottom of the spreadsheet.
You can use Application.ConvertFormula to make the formula relative to some other cell. If I'm in row 5 and the start of my range is in row 2, I make the formula relative to row 8. That way the R[-3] will put the formula in A5 as $G5 (three rows up from A8).
Sub test()
Dim cstrDefaultProgressColumn As String
Dim sFormula As String
cstrDefaultProgressColumn = "$G"
With ActiveSheet.UsedRange.Offset(1)
.FormatConditions.Delete
'set used row range to green interior color, if "Erledigt Datum" is not empty
'Build formula
sFormula = "=ISBLANK(" & cstrDefaultProgressColumn & .Row & ")"
'convert to r1c1
sFormula = Application.ConvertFormula(sFormula, xlA1, xlR1C1)
'convert to a1 and make relative
sFormula = Application.ConvertFormula(sFormula, xlR1C1, xlA1, , ActiveCell.Offset(ActiveCell.Row - .Cells(1).Row))
With .FormatConditions.Add(Type:=xlExpression, _
Formula1:=sFormula)
.Interior.ColorIndex = 4
End With
End With
End Sub
I only offset .Cells(1) row-wise because the column is absolute in this example. If both row and column are relative in your CF formula, you need more offsetting. Also, this only works if the active cell is below the first cell in your range. To make it more general purpose, you would have to determine where the activecell is relative to the range and offset appropriately. If the offset put you above row 1, you would need to code it so that it referred to a cell nearer the bottom of the total number of rows for your version of Excel.
If you thought selecting was a bit of a kludge, I'm sure you'll agree that this is worse. Even though I abhor unnecessary Selecting and Activating, Conditional Formatting and Data Validation are two places where it's a necessary evil.
A brief example:
Sub Format_Range()
Dim oRange As Range
Dim iRange_Rows As Integer
Dim iCnt As Integer
'First, create a named range manually in Excel (eg. "FORMAT_RANGE")
'In your case that would be range "$A$5:$H$25".
'You only need to do this once,
'through VBA you can afterwards dynamically adapt size + location at any time.
'If you don't feel comfortable with that, you can create headers
'and look for the headers dynamically in the sheet to retrieve
'their position dynamically too.
'Setting this range makes it independent
'from which sheet in the workbook is active
'No unnecessary .Activate is needed and certainly no hard coded "A1" cell.
'(which makes it more potentially subject to bugs later on)
Set oRange = ThisWorkbook.Names("FORMAT_RANGE").RefersToRange
iRange_Rows = oRange.Rows.Count
For iCnt = 1 To iRange_Rows
If oRange(iCnt, 1) <> oRange(iCnt, 2) Then
oRange(iCnt, 2).Interior.ColorIndex = 4
End If
Next iCnt
End Sub
Regarding my comments given on the other reply:
If you have to do this for many rows, it is definitely faster to load the the entire range into memory (an array) and check the conditions within the array, after which you do the writing on those cells that need to be written (formatted).
I could agree that this technique is not "necessary" in this case - however it is good practise because it is flexible for many (any type of) customizations afterwards and easier to debug (using the immediate / locals / watches window).
I'm not a fan of Offset although I don't state it doesn't work as it should and in some limited scenarios I could say that the chance for problems "could" be small: I experienced that some business users tend to use it constantly (here offset +3, there offset -3, then again -2, etc...); although it is easy to write, I can tell you it is hell to revise. It is also very often subject to bugs when changes are made by end users.
I am very much "for" the use of headers (although I'm also a fan of reducing database capabilities for Excel, because for many it results in avoiding Access), because it will allow you very much flexibility. Even when I used columns 1 and 2; better is it to retrieve the column nr dynamically based on the location of the named range of the header. If then another column is inserted, no bugs will appear.
Last but not least, it may sound exaggerated, but the last time, I used a class module with properties and functions to perform all retrievals of potential data within each sheet dynamically, perform checks on all bugs I could think of and some additional functions to execute specific tasks.
So if you need many types of data from a specific sheet, you can instantiate that class and have all the data at your disposal, accessible through defined functions. I haven't noticed anyone doing it so far, but it gives you few trouble despite a little bit more work (you can use the same principles again over and over).
Now I don't think that this is what you need; but there may come a day that you need to make large tools for end users who don't know how it works but will complain a lot about things because of something they might have done themselves (even when it's not your "fault"); it's good to keep this in mind.
