How to get the return value of an exe which is called by shellexecute function.
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);
In the above example I want the return value of "dpinstx86.exe".
在上面的例子中，我想要“dpinstx86.exe”的返回值。

Use ShellExecuteExinstead to get the process handle, and GetExitCodeProcessto get the exit code.
使用ShellExecuteEx来获取进程句柄，并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);
