How to get the return value of an exe which is called by shellexecute function.

ShellExecute(NULL, NULL, TEXT ( ".\dpinstx86.exe" ), NULL, NULL, SW_SHOWNORMAL);

In the above example I want the return value of "dpinstx86.exe".

Answer 1

Use ShellExecuteEx instead to get the process handle, and GetExitCodeProcess to get the exit code.

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "c:\MyProgram.exe";        
ShExecInfo.lpParameters = "";   
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL; 
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE);
