Welcome to AutoIt! In most cases the functions indicate errors by return value and the @error macro when things don't work. The function _IEFormCollection($oIE, 0) will do both. It returns 0 instead of an object, and sets @error to some non-zero value. You can test the return value with IsObj(), and check @error with a straight IF: #include <IE.au3> $oIE = _IECreate("www.google.com") $oForm = _IEFormCollection($oIE, 0) If Not IsObj($oForm) Then MsgBox(16, "Error", "Failed to get form object.") $oForm = _IEFormCollection($oIE, 1) If @error Then MsgBox(16, "Error", "_IEFormCollection() returned @error = " & @error) If you are looking for help with a specific error, please post code to replicate the error and/or the Console text from SciTE.
