Hi, I'm trying to do some very basic Excel file manipulation. However, I can't even get AutoIt to open up Excel files for reading! My code is extremely simple, taken verbatim from the help files. #include <Excel.au3> $sFilePath1 = @ScriptDir & "\filename.xls"; open excel file $oExcel = _ExcelBookOpen($sFilePath1) If @error = 1 Then MsgBox(0, "Error!", "Unable to Create the Excel Object") Exit ElseIf @error = 2 Then MsgBox(0, "Error!", "File does not exist - Shame on you!")
