closing of a dialog box on button click problem!

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

Handle the WM_KILLFOCUS event and send a WM_CLOSE (also OnOK, OnCancel would solve ur problem) message to the dialog at the very end of this function.

Please tell me how to handle WM_KILLFOCUS message

Please tell me how to handle WM_KILLFOCUS message
In the same manner in which you handle other messages like WM_PAINT etc.... Write a OnKillFocus handler function for WM_KILLFOCUS and a corresponding entry should be added in the message map. Also do not forget to declare the function in the header file and then implement in the cpp file for your dialog that pops up

Add this to message map.
ON_WM_KILLFOCUS()
and add handler funciton
void CTrialMFCDlg::OnKillFocus(CWnd* pNewWnd)
{
CDialog::OnKillFocus(pNewWnd);// TODO: Add your message handler code here}
Also dont forget to add the handler declaration of the handler in class. I hope it helps. BTW: You can use class wizard to add the handler :)

This new dialog box is having 16 emoticons placed as bmp images on a button as is in the case of messanger . Now in the case when no emoticons is selected and the user clicks any arear outside the CEmoticons dialog I want the Dialog CEmoticons to be closed. Right now what i am able to do is that i need to select a emoticon and and on click event of it i am closing the dialog box as a result of which i need to select a smiley. So please help me as to in whcih class I have to use the above cod ewhich you have provided.

CEmoticonsDlg, since this is the dialog you want to be able to close by clicking on the background. (as in, not on any of the 16 buttons)

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.
