Faalamva Posted November 18, 2017 Share Posted November 18, 2017 (edited) Hello, A strange behaviour occured in my code, so I've stripped and stripped again its content, until I could confine and identify the very cause of the malfunction. Put under its simplest form, here it is : this kind of comparison is working, although at first sight it's no so evident why it is : If "338a" = 338 Then MsgBox(0, "", "Why oh why ?") EndIf I understand that comparing a string with an integer is a bit odd, however in the original code, I'm comparing variables from an array, and this array if filled from an Excel file through the _Excel_RangeRead function. The column of the Excel file can contain random values : some of them are 338 (interpreted as integer) and some others are 338a (interpreted as string). Now I can solve the problem by forcing the comparison like this : String(variable1) = String(variable2) where variable1 and variable2 can be of any type (coming from the Excel file). However I'd like to know the very reason why this comparison is working in the first place ? Please enlighten me !
