Hello,

I am working on an application C++/MFC with Visual Studio 2005.

I created a CDialog based application, and I use the
PreTranslateMessage() function to manage the messages received by the
main dialog of my app.

The problem is that when my dialog is displayed, and if I press a key,
it seems that sometimes, the OnOK() function is called by default, and
the dialog is automatically closed. And the breakpoint I set in the
PreTranslateMessage() function is never reached.

I'd like to avoid this behaviour, and disable this default OnOK()
function. I have no OnOK() function in my code, so I think it's the
CDialog::OnOK() function which is automatically called. I'd like also
to have the PreTranslateMessage() called for each keystroke, to be able
to manage the keys by myself.

Can somebody help me on this point ? Thank you.

To get the good results here, use the following code

BOOL CPreTransTestDlg::PreTranslateMessage(MSG* pMsg)
{
    if(pMsg->message==WM_KEYDOWN)
    {
        if(pMsg->wParam==VK_RETURN)
            pMsg->wParam=VK_TAB;
    }
    return CDialog::PreTranslateMessage(pMsg);
}

Here this will convert the pressing of Enter key to VK_TAB and the
focus will move on to the next control in your dialog as if you have
pressed the Tab key. This is helpful while writing data entry kind of
applications where you have lots of edit controls and you want to move
to next control every time you press the Enter Key on keyboard....hope
that helps...
