ShellExecuteEx的使用方法

关于怎样在c++中启动外部的exe程序，之前看到在百度一搜就看到了：

               ShellExecute(this->m_hWnd,"open","calc.exe","","", SW_SHOW );

经验证果然能够，一条语句直接就启动了。之后我想在我的代码结束时也把这个exe程序给关闭了，依照网上的做法直接TerminateProcess(HINSTANCE,0)就不行了，參数根本就不能是HINSTANCE类型；然后使用sendMessage(WM_Close,...)也不行，原因应该是我的exe程序根本就没有窗体；最后使用了ShellExecuteEx，总算搞定了。

 

附上代码：

启动：

 SHELLEXECUTEINFO ShExecInfo;

 ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
 ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS ;
 ShExecInfo.hwnd = NULL;
 ShExecInfo.lpVerb = NULL;
 ShExecInfo.lpFile = "xxx.exe"; //can be a file as well
 ShExecInfo.lpParameters = "";
 ShExecInfo.lpDirectory = NULL;
 ShExecInfo.nShow = SW_SHOW;
 ShExecInfo.hInstApp = NULL;
 ShellExecuteEx(&ShExecInfo);

 

关闭：

 if( ShExecInfo.hProcess != NULL)
 {
      TerminateProcess(ShExecInfo.hProcess,0);
      ShExecInfo.hProcess = NULL;
 }
