i am developing an App for windows that will start some third party executable files such as cmd, paint, notepad etc using CreateProcess function. I want the functionality to hide and show the window of these EXE programs using HWND or suggest any other solution...
CreateProcess() does not return the HWND of the new process so you will have to find it manually. Use EnumWindows() and GetWindowThreadProcessId() to find HWNDs whose process/thread IDs match the same IDs that CreateProcess() returns in the PROCESS_INFORMATION struct. Once you have the HWNDs, you can use ShowWindow() to show/hide them as needed.
