Thanks!!! Hello Ziemenz, Just looking at EndTask funtion declaration, first parameter should be a HWND (a hadle to a Window that will be closed) not the process exe file name you try to close. Have a look at MSDN help on how to terminate a process. Dec

I can't use a handle on a window, I have to find the process ID and kill it. Do you have some suggestion?!? I think to use a.dll to make the job. Do you know if .net dll can be use with WinCC? Thanks!!!

Like I said before the best source of info is MSDN since WinCC will call into Windows sdk libraries (psapi.dll, kernel32.dll etc). Perhaps you will make use of EnumProcesses to get an array of all processes running, andthen you will parse each process on this array using OpenProcess / EnumProcessModules / GetModuleBaseName until you find the match with "PCAConfig.exe", and then use TerminateProcessfor that handle.
