在VC程序中如何結(jié)束系統(tǒng)正在運行的其他進程（該進程必須有窗口界面），其實很簡單，按如下步驟進行即可：
1.取得進程的句柄（利用FindWindow函數(shù)得到）；
2.獲取進程ID號（用GetWindowThreadProcessId函數(shù)獲?。?br> 3.打開進程，OpenProcess函數(shù)中的第一個參數(shù)設(shè)為PROCESS_TERMINATE，就可以獲取處理該進程的句柄；
4.利用TerminateProcess函數(shù)結(jié)束進程，將該函數(shù)的第二個參數(shù)設(shè)為4。
代碼如下：
//結(jié)束進程
int CStaticFunc::KillProcess(LPCSTR pszClassName, LPCSTR
pszWindowTitle)
{
HANDLE hProcessHandle;
ULONG nProcessID;
HWND TheWindow;
TheWindow = ::FindWindow( NULL, pszWindowTitle );
::GetWindowThreadProcessId( TheWindow, &nProcessID );
hProcessHandle = ::OpenProcess( PROCESS_TERMINATE, FALSE,
nProcessID );
return ::TerminateProcess( hProcessHandle, 4 );
}
而啟動進程則只需要CreateProcess函數(shù)就可完成，需要注意的是這個函數(shù)的幾個輸入?yún)?shù)，第一個參數(shù)是
//啟動新進程
int CStaticFunc::CreateNewProcess(LPCSTR pszExeName)
{
PROCESS_INFORMATION piProcInfoGPS;
STARTUPINFO siStartupInfo;
SECURITY_ATTRIBUTES saProcess, saThread;
ZeroMemory( &siStartupInfo, sizeof(siStartupInfo) );
siStartupInfo.cb = sizeof(siStartupInfo);
saProcess.nLength = sizeof(saProcess);
saProcess.lpSecurityDescriptor = NULL;
saProcess.bInheritHandle = true;
saThread.nLength = sizeof(saThread);
saThread.lpSecurityDescriptor = NULL;
saThread.bInheritHandle = true;
return ::CreateProcess( NULL, (LPTSTR)pszExeName, &saProcess,
&saThread, false,
CREATE_DEFAULT_ERROR_MODE, NULL, NULL,
&siStartupInfo, &piProcInfoGPS );
}
