If your VB application is meant to be called from within a Ms-Dos batch file, you must be able to return Dos an error code. This can be accomplished using the ExitProcess API function: Click here to copy the following block Private Declare Sub ExitProcess Lib "kernel32" (ByVal uExitCode As Long) ' terminate the program and return ErrorLevel = 3 ExitProcess 3 Note that the ExitProcess API function is similar to the END command, in that it prevents all the usual clean up code from executing. Therefore, you must call it only after you've manually closed all forms, files and databases, released all memory and resources allocated through Windows, etc. The following Ms-Dos batch program demonstrates how you can test the ErrorLevel returned by the VB application Click here to copy the following block START /W project1 REM ErrorLevel codes must be tested in reverse order IF ERRORLEVEL 5 GOTO Err5 IF ERRORLEVEL 4 GOTO Err4 IF ERRORLEVEL 3 GOTO Err3 IF ERRORLEVEL 2 GOTO Err2 IF ERRORLEVEL 1 GOTO Err1 ECHO ErrorLevel = 0 GOTO Exit :Err1 ECHO ErrorLevel = 1 GOTO Exit :Err2 ECHO ErrorLevel = 2 GOTO Exit :Err3 ECHO ErrorLevel = 3 GOTO Exit :Err4 ECHO ErrorLevel = 4 GOTO Exit :Err5 ECHO ErrorLevel = 5 :Exit REM End of batch file Note that you must use the syntax START /W if you're running under Windows 95.
