Determine if Your Program is Running Within VB’s IDE

Sometimes it is useful to know if your program is running within Visual Basic’s Integrated Development Environment (IDE) or as a standalone EXE. This routine returns True if the program is running within VB’s IDE:

 Public Function RunningInIDE() As Boolean	'Assume running as EXE for now	RunningInIDE = False	'Trap errors	On Error GoTo RunningInIDEErr	'Divide by zero (fails within IDE)	Debug.Print 1 / 0	'Exit if no error	Exit FunctionRunningInIDEErr:	'We get error if Debug.Print was	'evaluated (i.e. running in the VB IDE)	RunningInIDE = TrueEnd Function

RunningInIDE performs a division by zero in a Debug.Print statement. Within the IDE, this causes a divide overflow, which the function traps in an error handler. When the program is run as a standalone EXE, Debug.Print statements are not evaluated and no error occurs.
