VB Forum / Win API / November 2007vb6 calling an exe with shell, how to get the results when exe don
first I hope this is an okay question for this ng? Im trying to call an exe using vb6 which I can do already, that part works. but when the exe finishes I want to get the return values and use them in the code to tell the user the action passed/failed or whatever. I started by calling with shell command, tried several ways to catch the results? so the code just has a button and text box. button calls the exe, it seems to always return 0, but when it fails its supposed to return 1 - 7 based on the error. must not be doing the right thing button click starts the exe, when I close the exe file and return to vb code I want to catch the exit codes, how? thanks in advance > first I hope this is an okay question for this ng? > [quoted text clipped - 11 lines] > button click starts the exe, when I close the exe file and return to vb code > I want to catch the exit codes, how? Google for "ShellExecute and Wait". There are a couple of zillion ways.

What happens is that I just want to get the exit code when the called exe terminates and either Im not doing this right or the app itself is not returning the various exit codes in my code, GetExitCodeProcess proc.hProcess, RetVal2 RetVal2 is always -1 but then if I change it to RetVal = GetExitCodeProcess (proc.hProcess, RetVal2) and assume that proc.hProcess works fine, it starts and I can see the process number in the task manager associated with my expected exe application that Im starting up then here RetVal is always = 0 In the various sample programs, they seem to all use similar if not identical calls to kernel32 functions. So now Im left wondering if the application doesnt actually return various exit codes, or Im not doing the right thing to discover them. Contacting the person responsible for the app itself, I get an out of office reply... > > first I hope this is an okay question for this ng? > > [quoted text clipped - 32 lines] > Another... > http://www.vbaccelerator.com/home/vb/code/libraries/Shell_Projects/Shell_And_Wai t_For_Completion/article.asp Ok I figured it out, using one of the original main links I followed it out and found it, http://support.microsoft.com/kb/129796/EN-US/ quote... Getting the Exit Code from the Shelled Application It was common for a DOS application to return an exit code indicating the status of the completed application. While Windows provides other ways to convey the same information, some applications only provide exit codes. Passing the process handle to the GetExitCodeProcess() API allows you to retrieve this information. I made a new app, copied and pasted the example, inserted my app for notepad and it works perfect Using this, it also shows that the app in question returns code 0 all the time thanks > Thanks Ralph thats very helpful, Ive checked all of those examples and tried > them.
