KEYUP and KEYDOWN EVENT

[amoyao]

Please, i need help!!

I have an MFC dialog based application, it has a dialog with some edit controls, i need to know when the user press an "enter key" or an "arrow up" or an "arrow down" in a specific edit control. I suposse i have to use the OnKeyUp event, but I don´t know how to do it, when i search this message in the classwizard i didn't find it
Does anybody have an example?

I hope you understand my english, thanks anyway!!

Saludos

You can 1) subclass the edit control or 2) use PreTranslateMessage to capture the keypress.

BOOL CWinCvtDlg::PreTranslateMessage(MSG *pMsg)
{
    /*++
     If delete key is hit, and the window
     that has focus is the is the listctrl,
     call the default delete item function
    --*/
    if(pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_DELETE && pMsg->hwnd == m_FileListCtrl.GetSafeHwnd())
    {
        OnBtnRemove();
        return TRUE; // handled...
    }

    return CDialog::PreTranslateMessage(pMsg);
} 

That's a function I wrote a bit back, figured it might help. It caputres key down and sees if the window that received the press was the same window as my list ctrl, and if it was it triggered the OnBtnRemoved function, otherwise it let the CDialog do as it needed

Take a look at this FAQ for further information on the topic...

Thanks a lot! That really works

[Sam Hobbs]

What works? PreTranslateMessage? MFC experts don't use it because they know easier ways to do it. See the CodeGuru article for the solutions used by MFC experts.

Hi!

Dou you mean that i shouldn't use Pretranslate messages???
Why?
Dou yo have the link for the article that you mentioned???

Yeah there is a better way of doing the OK button, described in the FAQ that Andreas posted to you earlier. It works, yes, but it's not a real good way of doing it for your case.

Look at the link at the bottom of the FAQ item that Andreas posted and that Eli reposted; the part just before "written by Sam Hobbs".

Why are you hijacking a 5 year old thread....Have YOU been working on theis SPECIFIC problem for the last five years????

Ask a moderator to plit your post off to a new thread, then wait for them to do so......

I know that this latest couple of replies are nearly a month old but I have been trying since September to sign in to CodeGuru and I was unsuccessful until now.

Note that this was the first and only post by the person; I think you scared them off.

Ask a moderator to plit your post off to a new thread, then wait for them to do so......

Or the person could create a new thread. They could post a message here when they do, so that everyone knows to answer that thread.

Or you could suggest the person read Processing Keyboard Messages.
