Make Enter Key Work Tab Key in CEdit, PreTranslateMessage(MSG* pMsg) question.
I'm try to override the Enter Key and make it act like a Tab Key to go to the next control but it's not working. How can I return TabKey excution in the following code?
TIA
BOOL CEditCustom::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
// ENTER key
if((pMsg->message == WM_KEYDOWN) &&
(pMsg->wParam == VK_RETURN))
{
// Enter key was hit -> do whatever you want
AfxMessageBox("The Enter Key was Hit");
pMsg->wParam = VK_TAB;
//this->SendMessage(WM_KILLFOCUS);
return TRUE;
}
return CEdit::PreTranslateMessage(pMsg);
}

Changing the Behavior of Enter with DLGKEYS Sample App? ( http://msdn.microsoft.com/msdnmag/issues/0700/c/default.aspx)

Using PreTranslateMessage is similar to a aspirin prescription from the doctor who does not know what is wrong with you.
You should not use PreTranslateMessage. You can use code as in the sample below:
UINT CAllKeysEdit::OnGetDlgCode()
{
return /*CEdit::OnGetDlgCode()*/ DLGC_WANTALLKEYS;
}
void CAllKeysEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if(VK_RETURN == nChar || VK_TAB == nChar)
{
CDialog *pParent = (CDialog*)GetParent();
pParent->NextDlgCtrl();
return;
}
CEdit::OnChar(nChar, nRepCnt, nFlags);
}

The following works
BOOL CEditCustom::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
// ENTER key
if((pMsg->message == WM_KEYDOWN) &&
(pMsg->wParam == VK_RETURN))
{
// Enter key was hit -> do whatever you want
AfxMessageBox("The Enter Key was Hit");
pMsg->wParam = VK_TAB;
return CEdit::PreTranslateMessage(pMsg);
return TRUE;
}
return CEdit::PreTranslateMessage(pMsg);
}
I placed ' return CEdit::PreTranslateMessage(pMsg); ' in the section where you trap the VK_TAB key.

}
I got that to work too. Thanks.

In addition to JohnCz, take a look at When to use or not use PreTranslateMessage (http://www.flounder.com/messaging.htm)
