使用VC++ 6关闭指定窗口标题的程序

 #include <windows.h>

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam);

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.

EnumWindows(EnumWindowsProc, 0); //枚举所有窗口
return 0;
}

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam) //满足指定条件，则关闭窗口
{

char wtitle[512];
GetWindowText(hwnd, wtitle, sizeof(wtitle));
if (strstr(wtitle , "记事本")) //窗口标题含有记事本
{
::SendMessage(hwnd, WM_CLOSE, 0, 0);
}

return (true); //不要忘了
}
