I have used the following message handler but now on clicking the emoticon button the dialogbox CEmoticonDlg is not being opened. Please tell me whats the problem. Its urgent
void CEmotionsDlg::OnKillFocus(CWnd* pNewWnd)
{
CDialog::OnKillFocus(pNewWnd);
// TODO: Add your message handler code here
SendMessage(WM_CLOSE,0,0);
}This is how I am opening the CEmoticonDlg Dialog box
void CChatDlg::OnEmotions()
{
CEmotionsDlg m_EmotionsDlg(this);
m_EmotionsDlg.DoModal();
}Thanks In Advance

Your getting beyond anyone's ability to help you here. You need to put breakpoints in your code, and see what error codes are. My suspicion is your CEmotionsDlg is starting, and stopping almost straight away. Put a breakpoint in the OnKillFocus handler, and see if I'm right. Put a breakpoint in the OnInitDialog handler, see if it gets called. Put a breakpoint on the
m_EmotionsDlg.DoModal();line and follow the code inside. Do you get errors? If in doubt, put breakpoints everywhere! Maybe you have a breakpoint somewhere, and the act of swapping to the debugger is losing focus on your dialog, and... Iain. -

Well, your dialog is starting (which is good news), but it is also finishing too early. You need to find out why it's finishing early then. Ask yourself what you know about stopping dialog. Maybe the OnInitDialog is not working correctly. Maybe something in your code is stopping the dialog? Try a breakpoint in CDialog::EndDialog - it could tell you which bit of your code is killing the dialog. Same with OnClose... If you still can't find it, comment out 99% of the dialog code until it stays up. Then start putting code back again until it breaks. This is going to be a pain to track down, but none of it is rocket science. Just plod through your code until you find the offending line or two. Iain.

Ok I will try it.

Hi, I am working on an mfc application in which I am opening a dialog box containing smileys on button click. Now what I want is to close the dialog dialog box with smileys when mouse click event is fired anywhere on the screen. Thanks Dhiraj Kumar Saini
