代码如下：
HWND hWnd;
QT_WA( {
hWnd = ::FindWindow(L"TMainForm", L"AVC控制界面 [1.393]");
}, {
hWnd = ::FindWindowA("TMainForm", "AVC控制界面 [1.393]");
});
if (hWnd) {
QT_WA( {::PostMessage(hWnd, WM_USER_AVCRUN, WM_USER_AVCRUN_CLOSE, 0);
}, {
::PostMessageA(hWnd, WM_USER_AVCRUN, WM_USER_AVCRUN_CLOSE, 0);
});
}
郁闷中，请各位大侠帮忙，小弟不胜感激！！！
