Question

I need to do the following in a macro

If sFolderName contains ".pdf"
// Do Something
Else // Do Something
End If

but I do not know how to find out if .pdf is inside the variable or not.

Answer 1

In VBA, you can use the InStr function to search for the position of one string inside another string.

The syntax of the function is: InStr([start,]string1,string2[,compare])

In your scenario, string1 will be sFolderName and string2 would be ".pdf". In other words, you are searching for the position in sFolderName where the text “.pdf” begins.

If string2 is found within string1, then InStr returns the position at which match is found.

If InStr(sFolderName, ".pdf") > 0 Then
   // do something
Else
   // do something else
End If
