I am writing an Excel sheet with some buttons that run VBA.
each button essentially picks a cell at the beginning of the range that it will eventually use, a length(number of cells that will be used), and a couple of other parameters entered by the user, and then sends the information to a sub, which resizes the Range that currently contains one cell to the number of cells entered in the length
When I use
Sub GetFromCTLGX(RangeToFill As Range, Name, TagName, TagLength)
RangeToFill = RangeToFill.Resize(1, TagLength)
my Range, "RangeToFill" is not changed at all.
If I use
Sub GetFromCTLGX(RangeToFill As Range, Name, TagName, TagLength)
RangeToFill.Resize(1, TagLength)
the code faults and doesn't compile.
has anyone else run into this problem?
am I missing something?
I found the mistake in my code,
it should have been
Set RangeToFill= RangeToFill.Resize(1, TagLength)
it's odd though.... it still doesn't explain to me why just
RangeToFill.Resize(1, TagLength)
wasn't working, that's what is used in a majority of the examples I saw.
I'm surprised that there wasn't an error for not having the Set keyword there.
This example resizes the RangeToFill to extend it by one row and one column.
http://msdn.microsoft.com/en-us/library/office/ff193274%28v=office.15%29.aspx
numRows = RangeToFill.Rows.Count
numColumns = RangeToFill.Columns.Count
Set RangeToFill = RangeToFill.Resize(numRows + 1, numColumns + 1)

I literally just got my feet wet with VBA as this is my first macro. After many hours of searching, I couldn't seem to find an answer that had a solution that worked for me so here I am.
On Sheet3 I have 3 option buttons in a group box that are linked to cell "B18" on Sheet4 (Sheet4 is hidden to the user, a backstage if you will). When any of the three option buttons are selected, 'Sheet4!B18' gets updated as it should (e.g. 1, 2, or 3). What I want to happen is to have 'Sheet3!B17' changed based upon the value in 'Sheet4!B18', or effectively: IF('Sheet4!B18'=2,SET('Sheet3!B17'="Some Text Here:"),SET('Sheet3!B17'="0%")), but still allow user input in 'Sheet3!B17'. I have one VBA macro on Sheet4 with the following code:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Worksheet.Range("B18") = 2 Then
Worksheets("Sheet3").Range("B17") = "Some Text Here:"
Else
Worksheets("Sheet3").Range("B17") = "0%"
End If
End Sub
If I manually update 'Sheet4!B18' then the macro gets triggered with the desired results. If I use any of the 3 option buttons on Sheet3, the macro does not get triggered even though the target cell is getting updated.
In my searching I couldn't seem to find anything concrete, but from what I could tell the "Worksheet_Change" function doesn't see changes to cells from form control as changes to the linked cell are considered a "recalculation" as if it were from a formula. I don't know how correct that is, but my searching led me to believe that I would need another macro assigned on the 3 buttons and/or group box that when either of those get selected/changed, it would somehow trigger the working macro on Sheet4.
I thought that perhaps I could create a new macro that I would assign to the group box or option buttons themselves so I tried that and could not get anything to work. I tried adding the above macro code to another sub, Sub mode() and assigning to only the group box, then only the buttons, but nothing happened in either case. I proceeded to try tweaking the code just in case the references were not correct, but saw no change regardless of how I specified the reference. I am not getting any error messages, but nothing gets triggered unless I manually change the value in 'Sheet4!B18'.
Is there a way to get the first macro that I have working on Sheet4 to trigger off of the option buttons changing the target cell value, something like forcing it to look only at that one specific cell for changes? Am I stuck making another macro for the buttons and/or group box to trigger the macro on Sheet4? Am I over-complicating this and there is some built in Excel sheets function(s) that I can use?
IF/THEN is a fine way to do it. VBA also supports ternary logic with the IIF function, like this:
Worksheets("Sheet3").Range("B17") = IIF(Worksheets("Sheet4").Range("B18") = 2, "Some Text Here:", "0%")
That may seem a little difficult to read, but it's a good concept to understand, since it's present in many languages, and usually with a more simplified implementation that makes it very useful and concise.
Also, I would suggest making a couple of other alterations that may make your code easier to write, read and maintain (especially as it becomes more complex).
First, alias the worksheets, something like this:
Dim this as Worksheet: Set this = Worksheets("Sheet3")
Dim that as Worksheet: Set that = Worksheets("Sheet4")
Now you would be able to rewrite your code like this:
If that.Range("B18") = 2 Then
this.Range("B17") = "Some Text Here:"
Else
this.Range("B17") = "0%"
End If
And the ternary approach would now be:
this.Range("B17") = IIF(that.Range("B18") = 2, "Some Text Here:", "0%")
And you can get as specific as you like with the aliases. For instance, you could realias the ranges, instead of just the worksheets, like this:
Dim this as range: Set this = Worksheets("Sheet3").Range("B17")
Dim that as range: Set that = Worksheets("Sheet4").Range("B18")
this = IIf(that = 2, "Some Text Here:", "0%")
Also, I find it easier to use the cells property than the range property, especially when you start having to do cell math. In that case, Range("B17") becomes Cells(17, 2).
You can also change the way the cells are referenced in the spreadsheet by typing Application.ReferenceStyle = xlR1C1 into the immediate window. That way you don't have to mentally convert between A2 style ranges to Cartesian style (2,1).
Sometimes you just have to go through your entire thought process and type everything out before you have an "ah-hah!" moment because that is exactly what I had happen. I said to myself, "Why can't I have just one macro that gets triggered by the option buttons that checks my linked cell then proceeds to update the cell I want?" Well, eventually I was able to find the right code and this is what worked perfectly:
Sub mode() ' mode is the name of this macro
If Worksheets("Sheet4").Range("B18") = 2 Then
Worksheets("Sheet3").Range("B17") = "Some Text Here:"
Else
Worksheets("Sheet3").Range("B17") = "0%"
End If
End Sub
As it turns out, I was overlooking the simple solution and the above macro is all I need once I assigned it to the 3 option buttons in my group box, but not the group box itself. Since users will not have access to the hidden Sheet4 and therefore 'Sheet4!B18' will never have manual user input, the macro I first had on Sheet4 could be removed safely. Due to the fact that the option buttons being chosen is the trigger for the assigned macro, it executes each time the option is changed and only when the option is changed. Perfect!
EDIT:
Thanks to Chris Strickland for some tips for better code! I went on to modify the above into what you see below for slightly better performance (using Cells() instead of Range()), to save the original value to another cell and restore it if option 1 or 3 were selected, used aliases, and finally the IIf operator.
Sub mode() ' mode is the name of this macro
Dim S3 As Worksheet: Set S3 = Worksheets("Sheet3")
Dim S4 As Worksheet: Set S4 = Worksheets("Sheet4")
If IsNumeric(Cells(17, 2)) = True Then
S3.Activate
S4.Cells(18, 3) = Cells(17, 2).Value
End If
S3.Cells(17, 2) = IIf(S4.Cells(18, 2) = 2, "Some Text Here:", S4.Cells(18, 3))
End Sub
I'm having some issues with an insheet function that I am writing in VBA for Excel. What I eventually am trying to achieve is an excel function which is called from within a cell on your worksheet, that outputs a range of data points underneath the cell from which it is called (like the excel function =BDP() of financial data provider Bloomberg). I cannot specify the output range beforehand because I don't know how many data points it is going to output.
The issue seems to be that excel does not allow you to edit cells on a sheet from within a function, apart from the cell from which the function is called.
I have created a simple program to isolate the problem, for the sake of this question.
The following function, when called from within an excel sheet via =test(10), should produce a list of integers from 1 to 10 underneath the cell from which it is called.
Function test(number As Integer)
For i = 1 To number
Application.Caller.Offset(i, 0) = i
Next i
End Function
The code is very simple, yet nothing happens on the worksheet from which this formula is called (except a #Value error sometimes). I have tried several other specifications of the code, like for instance:
Function test(number As Integer)
Dim tempRange As Range
Set tempRange = Worksheets("Sheet1").Range(Application.Caller.Address)
For i = 1 To number
tempRange.Offset(i, 0) = i
Next i
End Function
Strangely enough, in this last piece of code, the command "debug.print tempRange.address" does print out the address from which the function is called.
The problem seems to be updating values on the worksheet from within an insheet function. Could anybody please give some guidance as to whether it is possible to achieve this via a different method?
Thanks a lot, J
User defined functions are only allowed to alter the values of the cells they are entered into, because Excel's calculation method is built on that assumption.
Methods of bypassing this limitation usually involve scary things like caching the results and locations you want to change and then rewriting them in an after calculate event, whilst taking care of any possible circularity or infinite loops.
The simplest solution is to enter a multi-cell array formula into more cells than you will ever need.
But if you really need to do this I would recommend looking at Govert's Excel DNA which has some array resizer function.
Resizing Excel UDF results
Consider:
Public Function test(number As Integer)
Dim i As Long, ary()
ReDim ary(1 To number, 1 To 1)
For i = 1 To number
ary(i, 1) = i
Next i
test = ary
End Function
Select a block of cells (in this case from C1 through C10), and array enter:
=test(10)
Array formulas must be entered with Ctrl + Shift + Enter rather than just the Enter key.
I've been working all week to prepare a VBA application, which I'll be using in a meeting today. Unfortunately the code that has been running all week last week without a hitch, has decided to break over the weekend.
I constantly get Object variable or With block variable not set Run-time error '91' from this statement:
With Sheet5
Set adjrng = .Range(.Cells(.Range("G43:G60").Find(.Range("H39").Value).Row, 10), .Cells(.Range("G43:G60").Find(.Range("H39").Value).Row, 21))
End With
idea is to set a range in the row of the Range G43:G60 where the Value of H39 matches from Column 10 to Column 21.
Anybody spot the issue? My brainz are to nervous and sleepy this morning...
Thanks a bunch
Ben
EDIT:
After playing a bit with find and replace, the issue seems to be that excel has not yet properly calculated the "lookin" and "lookup" Ranges G43:G60 and H39. A simple recalculation didn't make excel rediscover the contents but when I used one of my input toggles to display a different value in those cells, and the went back to the original it did manage to find it.
Maybe using find for this is bad style, the find formula has these kind of hicups usually or any other comments on this? For now everything works fine again, but I'm afraid of running into these issues again. Any tips would thus still be appreciated.
EDIT: (from comment below)
We have a dynamic range (G43:J60) where unique identifiers are listed in column G and data is to the right. if something is changed in the data part of the range AND the lines uniqued identifier in column G matches the one in cell H39 a sub() is triggered via worksheet_ change intersect(target, adjrng) Defining that adjrng is the part that throws errors when find returns null.
I believe you are simply trying to set a range hoping that there will be two matches to the value in H39 within the G43:G60 range. While I avoid on Error Resume Next (never could adjust to the logic of breaking something in the hope to accomplish something), I always check that the values will be there when I look for them.
Dim rwUNIQ as long
Set adjrng = nothing
With Sheet5
if cbool(application.countif(.Range("G43:G60"), .Range("H39").Value)) then
rwUNIQ = application.match(.Range("H39").Value, .Range("G43:G60"), 0)
Set adjrng = .Cells(42 + rwUNIQ, 10).resize(1, 11)
end if
if not adjrng is nothing then
'do something with adjrng
end if
Set adjrng = nothing
End With
That checks to make sure that there are at least two H39 values in G43:G60 before proceeding. There is no further error control because we've counted at least two of them. You might want to compensate with an Else for when there isn't. If a single H39 value was found, you also might want to select a single row.
Remember that the .Find uses many parameters that were retained from the last time Find was used, whether in VBA or with a user on the worksheet. You have a real lack of parameters that specify the options that Find should use to proceed. e.g. xlPart or xlWhole, After:=what?, look in formulas or values, etc.
EDIT:* Modified the code to look for a single instance of the value in H39 and .Resize to expand the width (as per OP's comments).
I'm struggling a bit with VBA syntax tonight, and would appreciate your help.
I have a Userform that takes input through RefEdit fields, and stores that as a variable (range). (This is done through
set DurationRange = range(me.refedit1.value)
which was an earlier question of mine tonight.
This user form takes this range input, and outputs the range into a different sheet for further processing. What I would like to do is basically output the variable again.
I'm trying that with this code:
with worksheets("Data Output")
.range("a1").offset(0, counter) = "Durations" 'this line just creates a header cell
.range("a2").offset(0, counter) = DurationsRange 'this line should output the range into cell a2
End with
But although this outputs the string, it does nothing for the range. What is the proper method to output a range? I know I could do a for each loop, but I have so many ranges that that seems incredibly inefficient.
There are some possible answers:
1st. if your DurationRange is a single cell range than you need to improve your code only in this line:
.range("a2").offset(0, counter) = DurationsRange.Value 'Value property is important here
2nd. if your DurationRange consists of one single column and some rows then you could possibly use this solution:
.range("a2").offset(0, counter).Resize(DurationRange.Rows.Count) = DurationsRange.Value 'Value property is important here, too
Obviously, there are some other options which could be solved in similar way to 2nd example above.
I want to have/define a unique id for each data row in my Excel data sheet - such that I can use it when passing the data onwards and it stays the same when rows are added/deleted above it.
My thoughts are to use the ID attribute of Range (msdn link)
So, I have a user defined function (UDF) which I place in each row that gets/sets the ID as follows:
Dim gNextUniqueId As Integer
Public Function rbGetId(ticker As String)
On Error GoTo rbGetId_Error
Dim currCell As Range
'tried using Application.Caller direct, but gives same error
Set currCell = Range(Application.Caller.Address)
If currCell.id = "" Then
gNextUniqueId = gNextUniqueId + 1
'this line fails no matter what value I set it to.
currCell.id = Str(gNextUniqueId)
End If
rbGetId = ticker & currCell.id
Exit Function
rbGetId_Error:
rbGetId = "!ERROR:" & Err.Description
End Function
But this fails at the line mentioned with
"Application-defined or object-defined error"
I thought perhaps its one of those limitations of UDFs, but I also get the same error if I try it from code triggered from a ribbon button...
Any other suggestions on how to keep consistent ids - perhaps I should populate the cells via my ribbon button, finding cells without IDs and generating/setting the cell value of those...
EDIT:
As Ant thought, I have the sheet protected, but even in an unlocked cell it still fails. Unprotecting the sheet fixes the problem.... but I have used "Protect UserInterFaceOnly:=True" which should allow me to do this. If I manually allow "Edit Objects" when I protect the sheet it also works, but I don't see a programmatic option for that - and I need to call the Protect function in AutoOpen to enable the UserInterfaceOnly feature...
I guess I need to turn off/on protect around my ID setting - assuming that can be done in a UDF... which it seems it cannot, as that does not work - neither ActiveSheet.unprotect nor ActiveWorkbook.unprotect :(
Thanks in advance.
Chris
Okay...
It does appear that if the sheet is locked, macros do not have write access to low-level information such as ID.
However, I do not think it is possible to unprotect the sheet within a UDF. By design, UDFs are heavily restricted; I think having a cell formula control the sheet protection would break the formula paradigm that a cell formula affects a cell only.
See this page on the Microsoft website for more details.
I think this limits your options. You must either:
give up sheet protection
give up the UDF, use a Worksheet_Change event to capture cell changes and write to ID there
use a UDF that writes the ID into the cell value, rather than save to ID
The UDF approach is fraught with problems as you are trying to use something designed for calculation of a cell to make a permanent mark on the sheet.
Nonetheless, here's an example of a UDF you can use to stamp a "permanent" value onto a cell, which works on unlocked cells of a protected sheet. This one only works for single cells (although it could be adapted for an array formula).
Public Function CellMark()
Dim currCell As Range
Set currCell = Range(Application.Caller.Address)
Dim myId As String
' must be text; using .value will cause the formula to be called again
' and create a circular reference
myId = currCell.Text
If (Trim(myId) = "" Or Trim(myId) = "0") Then
myId = "ID-" & Format(CStr(gNextUniqueId), "00000")
gNextUniqueId = gNextUniqueId + 1
End If
CellMark = myId
End Function
This is quite flawed though. Using copy or the fillbox will, however, retain the previous copied value. Only by explicitly setting cells to be a new formula will it work. But if you enter in the formula into the cell again (just click it, hit ENTER) a new value is calculated - which is standard cell behaviour.
I think the Worksheet_Change event is the way to go, which has much more latitude. Here's a simple example that updates the ID of any cell changes. It could be tailored to your particular scenario. This function would need to be added to every Worksheet the ID setting behaviour is required on.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim currCell As Range
Set currCell = Target.Cells(1, 1)
Dim currId As String
currId = currCell.ID
If Trim(currCell.ID) = "" Then
Target.Parent.Unprotect
currCell.ID = CStr(gNextUniqueId)
Target.Parent.Protect
gNextUniqueId = gNextUniqueId + 1
End If
End Sub
Last note; in all cases, your ID counter will be reset if you re-open the worksheet (at least under the limited details presented in your example).
Hope this helps.
Concur with Ant - your code works fine here on Excel 2003 SP3.
I've also been able to use:
Set currCell = Application.Caller
If Application.Caller.ID = "" Then
gNextUniqueId = gNextUniqueId + 1
'this line fails no matter what value I set it to.
currCell.ID = Str(gNextUniqueId)
End If
Aha! I think I have it.
I think you're calling this from an array formula, and it only gets called ONCE with the full range. You can't obtain an ID for a range - only a single cell. This explains why Application.Caller.ID fails for you, because Range("A1:B9").ID generates an Application-defined or object-defined error.
When you use Range(Application.Caller.Address) to get the "cell" you just defer this error down to the currCell.ID line.
I think we may have a few issues going on here, but I think they are testing issues, not problems with the code itself. First, if you call the function from anything other than a Cell, like the immediate window, other code, etc. Application.Caller will not be set. This is what is generating your object not found errors. Second, if you copy/paste the cell that has the function, they you will by copy/pasting the ID too. So wherever you paste it to, the output will stay the same. But if you just copy the text (instead of the cell), and then paste then this will work fine. (Including your original use of Application.Caller.)
The problem is with Application.Caller.
Since you are calling it from a user defined function it is going to pass you an error description. Here is the remark in the Help file.
Remarks
This property returns information about how Visual Basic was called, as shown in the following table.
Caller - Return value
A custom function entered in a single cell - A Range object specifying that cell
A custom function that is part of an array formula in a range of cells - A Range object specifying that range of cells
An Auto_Open, Auto_Close, Auto_Activate, or Auto_Deactivate macro - The name of the document as text
A macro set by either the OnDoubleClick or OnEntry property - The name of the chart object identifier or cell reference (if applicable) to which the macro applies
The Macro dialog box (Tools menu), or any caller not described above - The #REF! error value
Since you are calling it from a user defined function, what is happening is Application.Caller is returning a String of an error code to your range variable curCell. It is NOT causing an error which your error handler would pick up. What happens after that is you reference curCell, it's not actually a range anymore. On my machine it tries setting curCell = Range("Error 2023"). Whatever that object is, it might not have an ID attribute anymore and when you try to set it, it's throwing you that object error.
Here's what I would try...
Try removing your error handler and see if VBA throws up any exceptions on Range(Application.Caller.Address). This won't fix it, but it could point you in the right direction.
Either through logic or Application.ActiveCell or however you want to do it, reference the cell directly. For example Range("A1") or Cells(1,1). Application.Caller.Address just doesn't seem like a good option to use.
Try using Option Explicit. This might make the line where you set curCell throw up an error since Range(Application.Caller.Address) doesn't look like it's passing a range back, which is curCell's datatype.
I have found that if I protect the sheet with "Protect DrawingObjects:=False", the UDF can set the Id. Strange.
Thanks for all the help with this.
