No. The control will be clipped by the dialog. You can set it to whatever size you like, but only the part inside the dialog will be visible.

Dear Fiends,

override your OnOK and OnCancel of your Dialog. And comment out the
CDialog::OnOK() or CDialog::OnCancel()

Just check Michael Dunn FAQ article for detail.

Override OnOK().

CMyDialog::OnOK()
{
  PostMessage (WM_COMMAND, IDC_SOME_BUTTON);
}

Create two member functions for you dlg class.
Eg.

void CTestDlg::OnOK()
{
}

void CTestDlg::OnCancel()
{
}

Enough... Go and press any key in ur dialog... it wont close (even ur close button too;))

To close ur dialog Add OnClose() Message Handler to your dlg class

void CTestDlg::OnClose()
{
EndDialog(0);
CDialog::OnClose();
}

now press you close button. It will close Smile | :)

well you could set the focus on that button, when pressing enter that will activate it.
Other way is capturing the WM_KEYDOWN message in pretranslate func and check wParam for VK_RETURN.

Hope this helps you...

Cwnd::SetFocus();

if you use this into OnInitDialog(), you should switch its return value to FALSE.

Hey,

I have a couple of combo boxes, and When they hit new in the menu, I want it to clear, but when I use the m_varible.clear() command, it only clears the one I have highlighted or the last one I selected.

How do I get it to clear all of them?

Here is the code:

<br />
void CDEPDlg::OnFileNew() <br />
{<br />
	// TODO: Add your command handler code here<br />
		m_type1.Clear();<br />
		m_type2.Clear();<br />
		m_type3.Clear();<br />
		m_type4.Clear();<br />
		m_type5.Clear();<br />
}<br />
<br />

Thanks for any help

// Delete every other item from the combo box.
for (int i=0;i < pmyComboBox->GetCount();i++)
{
   pmyComboBox->DeleteString( i );
}

If you are using MFC.

You could store your password or other data to your CWinApp

And you could just call

((CYourApp*)AfxGetApp())->m_strPass ;

Or you could consider bad coding design but easier(my opinion)

global variable through

extern LPCTSTR g_YourPassword;

There are plenty of ways to do it. However, when you are storing sensitive data, you need to be more precautious in your design like consider encryption and etc.
