c++ win32调用exe,并等待其结束

调用exe 有诸如 ShellExecute(Ex) , System 之类的函数，本文以ShellExecuteEx为例子，调用exe，并等待其结束。

char ActiveCmd[200] ={0};
sprintf(ActiveCmd, "%s %s", argv[1] , argv[2] );
printf( "%s\n", ActiveCmd);

/** 转换char * ---> TCHAR **/
int actcnt = MultiByteToWideChar(CP_ACP, NULL, ActiveCmd, -1, NULL, 0);
TCHAR * pbuffer = new TCHAR[actcnt + 1];
memset(pbuffer, 0, sizeof(pbuffer));
MultiByteToWideChar(CP_ACP, NULL, ActiveCmd, -1, pbuffer, actcnt);

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = L"open";//多种类别有 "explorer" "print" 等
ShExecInfo.lpFile = EXE_FILE;//exe 路径
ShExecInfo.lpParameters = pbuffer;//参数
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_HIDE;//
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);

printf("waiting... \n ");
WaitForSingleObject(ShExecInfo.hProcess, INFINITE);//等待完成 第二个参数是超时时间（毫秒）超时后返回超时代码

delete pbuffer;

pbuffer = NULL;

也可以简单的调用：

::ShellExecute(NULL, NULL, EXE_PATH , pbuffer, NULL,SW_HIDE);//pbuffer 同上需要是 TCHAR*
