Still one hair remaining... not for long
This :
Function Around(Compare As String)
Around = (Range(Compare).Value = Range(Compare).Offset(-1, 0).Value) Or (Range(Compare).Value = Range(Compare).Offset(1, 0).Value)
End Function
generates a #VALUE! in the cell that calls it
I cannot figure out why
Any clues ?
I think #Value error while accessing user defined function in VBA does not apply here.
I'm guessing you're typing the formula in like =Around(E8), when you need to type it in as =Around("E8") since Compare is a String:
If you want to type it without quotation marks, then you need to declare Compare as a Range and change some syntax:
Function Around(Compare As Range)
Around = (Compare.Value = Compare.Offset(-1, 0).Value) Or (Compare.Value = Compare.Offset(1, 0).Value)
End Function

I have essentially a simple syntax question concering Application.Run. I want to write a bit of code where I pass a UDF a string coantaining the name of a worksheet function, e.g. 'iserror' or some other UDF returning boolean. The function will then be exectued for each cell within the passed range and do something depending on result.
However, I have not been able to work out the proper Syntax. Error Messages Change along with my Trials, but non are particularly helpfull. e.g.:
?hrCull(Range("Data!A1:B10"),"Worksheetfunction.iserror", False)
(Error message in German, I'll try my best to translate, but it probably won't 100% match the English Version):
Runtime error 1004:
The macro 'Worksheetfunction.iserror' can not be exectued. The macro may not be available in this worksheet or macros have been deactivated.
Of course, macros have not been deactivated, but it isn't really a macro anyway. Also tried without the leading 'Worksheetfunction', same error message.
In my code the call Looks like this:
Public Function hrCull(r As Range, func As String, Optional invert As Boolean = False) As Range
Dim c As Range
Dim selector As Boolean
...
selector = Application.Run(func, c)
...
end function
I omitted code not relevant.
So what is the proper Syntax?
Misc:
- I'm Aware that I can not assert that the passed function returns a boolean.
- Excel 2016 on Windows 7
A solution using CallByName:
selector = CallByName(Application.WorksheetFunction, "IsError", VbMethod, c)
Lose the WorksheetFunction. prefix, Evaluate doesn't like it as Evaluate is for worksheet functions.
In your function, use:
selector = Application.Evaluate(func & "(" & c.Address & ")")
To test, use:
Debug.Print hrCull(Range("A1"), "ISERROR")
I think you'd be better off declaring your own Enum and adding the functions that you want into this. Then execute them using built in syntax instead of trying to evaluate a string
Public Enum xlSheetFunction
xlIsError
End Enum
Public Function hrCull(r As Range, func As xlSheetFunction, Optional Invert As Boolean = False) As Range
Dim selector As Boolean
Select Case func
Case xlIsError
selector = WorksheetFunction.IsError(r)
End Select
Debug.Print selector
Set hrCull = r
End Function
Public Sub test()
Debug.Print hrCull(Range("A1"), xlIsError)
End Sub
Im writing an If+Or function and would like to use several cell references for the different Logicals in the function, instead of writing each logical statements in the original if+or function. Any ideas of how to solve this? Hope im not too unclear here..
As example: instead of writing =If(or(A1=A2,A3=A4),A1,0) I would like to write out all different logical values in a list of cells, and the just write the original if+or formula like this: =IF(OR(B1),A1,0) where B1 contains the text "A1=A2,A3=A4"
Thanks for any help on this!
You can use the INDIRECT function.
For example, if the value in cell A6 is 10, INDIRECT("A6") = 10.
So basically you can write INDIRECT("A6")=INDIRECT("A7") instead of the A1=A2 condition in your IF formula.
If you want to have "A1=A2" in one cell, you can use LEFT and RIGHT.
Here is an example: https://docs.google.com/spreadsheets/d/157tRicA55TFKKOi86yYBQScnjaQE6fYxaCHFdZx4uUM/edit?usp=sharing
PS: this solution is for Google Sheets so the solution might differ a little if you're using Excel but that should work for Excel too.
You CANNOT Have It All
Instead of using =IF(OR(B1),A1,0) you have to use
e.g. =IFOR(B1,A1) (I prefer "" instead of 0, sorry)
or =IFOR(B1,A1,0) if you (prefer 0 instead of ""),
or change the ElseValue in the declaration to 0,
then you can use =IFOR(B1,A1) to get 0.
Function IFOR(IfOrCell As Range, ThenCell As Range, _
Optional ElseValue As Variant = "", _
Optional SplitDelimiter As String = ",") As Variant
'Description:
'Pending...
'Recalculation
Application.Volatile
'Variables
Dim arrIfOr As Variant
Dim iIfOr As Integer
Dim blnIfOr As Boolean
'The Array: The Split
If InStr(IfOrCell.Value2, SplitDelimiter) = 0 Then Exit Function
arrIfOr = Split(IfOrCell.Value2, SplitDelimiter)
'An Additional Split Introducing the Boolean
For iIfOr = LBound(arrIfOr) To UBound(arrIfOr)
If InStr(arrIfOr(iIfOr), "=") <> 0 Then
If Range(Split(arrIfOr(iIfOr), "=")(0)).Value2 _
= Range(Split(arrIfOr(iIfOr), "=")(1)).Value2 Then
blnIfOr = True
Exit For
End If
End If
Next
'Output
If blnIfOr = True Then
IFOR = ThenCell.Value2
Else
IFOR = ElseValue
End If
End Function
i have created user defined function to calculate football match results.
My Root Function looks that:
Function calculatePoints(personTypes As Range, matchesResults As Range) As Integer
calculatePoints = getAllPersonPoints(personTypes, matchesResults)
End Function
getAllPersonPoints function:
Private Function getAllPersonPoints(personTypes As Range, matchesResults
AsRange) As Integer
Dim x As Long
Dim y As Long
Dim isTheSurest As Boolean
getAllPersonPoints = 0
For x = 1 To personTypes.Rows.Count
For y = 1 To personTypes.Columns.Count
isTheSurest = isTheSurestResult(personTypes.Cells(x,
y).DisplayFormat.Interior.PatternColorIndex)
getAllPersonPoints = getAllPersonPoints +
getPoints(matchesResults.Cells(x, y).Value, personTypes.Cells(x, y).Value,
isTheSurest)
Next y
Next x
End Function
When i am trying to call this function by setting manually parameters: personTypes range and matchesResults ragne - everythink works fine.
But when i am trying to call it from sheet i got #VALUE error in selected cell.
But at function form there is correct result:
A have been trying to debug return value and always i got correct value. I have problem only with error in return cell.
Any ideas ?
The issue is that DisplayFormat object does not work with UDF's
See MSDN article
The usual solution to this is to evaluate the Conditional Format conditions to determine which one is active. For example, see cpearson.com
I resolved problem by code:
personTypes.Cells(x, y).Interior.ColorIndex
instead of:
personTypes.Cells(x,y).DisplayFormat.Interior.PatternColorIndex
This solution works.
I need help to change the following function into VBA code. This will be part of a larger code.
IF((WEEKDAY($B12)=7),$I12,"")
There are probably more than 5 ways to do what you want, depending on what exactly do you need. One of these ways is to build a simple custom formula like this:
Public Function changingIfAndWeekday() As Variant
Application.Volatile
If Weekday(Range("B12")) = 7 Then
changingIfAndWeekday = Range("I12")
Else
changingIfAndWeekday = ""
End If
End Function
You could also do it like so (if you want the result on cell C12):
Sheet1.range("C12").value = "=IF(Weekday(Sheet1.range("B12").value = 7),Sheet1.range("I12").value,"")
You could also do it like so (if you want the result on a variable):
Variable = "=IF(Weekday(Sheet1.range("B12").value = 7),Sheet1.range("I12").value,"")
I am trying to execute the following string as code using Evaluate but get Error 2029. Anyone know why?
Help much appreciated.
Calculation = "Format(""21/08/2012"", ""MMM"")"
Value = Evaluate(Calculation)
Try instead
Calculation = "TEXT(""21/08/2012"", ""MMM"")"
EVALUATE converts formulas to results, and FORMAT is a VBA function. The formula equivalent is TEXT.
You can also skip the evaluate and use the FORMAT function on the date directly.
You can use most worksheet functions in VBA directly with Application.WorksheetFunction. - for example - try this out:
Sub DateExample()
Dim StringTest As String
StringTest = Application.WorksheetFunction.Text("12/08/2012", "MMM")
Cells(1, 1).Value = StringTest
End Sub
Good Luck
