c – 如何获取ShellExecute调用的exe的返回值

如何获取由 shellexecute函数调用的exe的返回值.

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

在上面的例子中,我想要“dpinstx86.exe”的返回值.

解决方法

使用 ShellExecuteEx取代过程句柄,并使用 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);
