自动关闭MessageBox()对话框

方法1：（模拟回车实现）

SetTimer(1,1000,NULL);
MessageBox("Test","Test1");

在OnTimer(UINT nIDEvent) 中

if(nIDEvent == 1)
{
KillTimer(1);
// DestroyWindow(); //可以用这个

keybd_event(VK_RETURN,0,0,0);
keybd_event(VK_RETURN,0,KEYEVENTF_KEYUP,0);//模拟"回车"命令

}

方法2：GetForegroundWindow()得到句柄 SendMessageCallback发送消息

void CYSWDlg::OnButton1()
{
// TODO: Add your control notification handler code here
SetTimer(1, 1000, TimerProc) ;
MessageBox("试一下", "哈哈", MB_OK + MB_ICONINFORMATION);
KillTimer(1);

// CDialog::OnOK();
}

VOID CALLBACK TimerProc(HWND hwnd, UINT message, UINT iTimerID, DWORD dwTime)
{
SendMessageCallback(GetForegroundWindow(), WM_CLOSE, 0, 0, 0, 0);
}

方法3:调用 FindWindowEx 而不是 FindWindow

CDialog dlg(IDD_DIALOG1);
SetTimer(1,1000,NULL);
MessageBox("Test","Test1",1);
// dlg.DoModal();

在void CMy11Dlg::OnTimer(UINT nIDEvent) 中

if(nIDEvent==1)
{
KillTimer(1);
// HANDLE hwd=FindWindowEx(NULL,NULL,NULL,"Dialog");
HANDLE hwd=FindWindowEx(NULL,NULL,NULL,"11");

if(hwd)
::SendMessage((HWND)hwd,WM_CLOSE,NULL,NULL);
}

可以实现关闭主对话框 MessageBox对话框 DoModal对话框 呵呵终于完功.

常见错误提示:

MessageBox("Test","Test1",1);

HANDLE hwd=FindWindowEx(NULL,NULL,NULL,"Test1");//执行不到

if(hwd)
::SendMessage((HWND)hwd,WM_CLOSE,NULL,NULL);

他执行到MessageBox("Test","Test1",1);时候,主线程就挂起了,不往下执行了,等你点确定,才会再往下执行,你加段点跟踪就知道了.

注意:必须用定时器才能实现.只有通过计时器来,启动另外线程来控制它.
主线程被挂起了,只有用其它线程来帮忙了
