Quick Array Question

[Anonymous]

I have this function which splits a string and converts it to an array. It works fine with numbers, but when the entry becomes text it doesn't seem to work. What is wrong with my code?

IF varpoints = "Double,Array"

Function stringToDblArray(VarPoints)
Dim StrAr() As Variant
VarPoints = VBA.Split(VarPoints, ",")
If IsNumeric(VarPoints) Then
ReDim ptaRr(UBound(VarPoints)) As Double

Dim i As Integer
For i = 0 To UBound(VarPoints)
ptaRr(i) = CDbl(VarPoints(i))
Next i
Else
ReDim StrAr(UBound(VarPoints)) As Variant
For i = 0 To UBound(VarPoints)
StrAr(i) = CStr(VarPoints(i))
Next i
End If
stringToDblArray = ptaRr

End Function

Because of IsNumeric, your logic will never enter the If structure when the argument is text.

Change this line
ReDim StrAr(UBound(VarPoints)) As Variant
on
ReDim StrAr(UBound(VarPoints)) As String

Will this helps?

I've tried changing from Variant to String and it still gives me an error subscript out of range.

Could i possibly check each index of varpoints before it redim's to see if it is numeric since isnumeric will prevent it from ever entering the if statement?

First, you pass wrong variable into Split function
See help. This would be a string expression not a variant
Try this one, seems to be working for me
