c++ - 如何获取 ShellExecute 调用的 exe 的返回值

Question

如何获取shellexecute函数调用的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。

使用 ShellExecuteEx而是获取进程句柄和 GetExitCodeProcess获取退出代码。

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);
