如何獲取由ShellExecute調用的exe的返回值

Question

如何獲取由shellexecute函數調用的exe的返回值。

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

在上面的例子中，我想要「dpinstx86.exe」的返回值。

改用ShellExecuteEx來取得進程句柄，而GetExitCodeProcess得到退出碼。

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);
