Kill Process at end of program ?

[Richard Chidiak]

Antonio,

In many cases especially when using Ftp, the program remains in memory after quitting the app , all connexions are properly closed by the app.

Is there a way to "kill all process issued by the program" ? and make sure it is ended in anyway ?

I often have to reset completely my Hp Ipaq to run my app again.

Thanks for your help,

Richard

Richard,

I use this code for testing "sleep" program process.

Thank you

Best regards

Richard,

Have you tried TerminateProcess( GetModuleHandle( 0 ), 0 ) ?

[Richard Chidiak]

Antonio

I will try this solution first and report if it is OK

Thanks

Richard

Antonio,

Your solution is fine to "end the program" , it works OK.

I like Pawel's idea of killing all sleeping process. I think about a gprs connexion that did not close properly etc.. .This can be a great add on to fwppc at the end of the app if it could be executed auomatically.

I am having problems compiling pawel's code.

Do i need any particular header files different than the standard ones windows.h and hbapi.h ?

Thanks for the help

Richard

Richard,

Add your source tlhelp32.h and link app with toolhelp.lib.
