in vs 6 how do you remove a .h or .cpp file if you added it by mistake?
i know you can exclude it from the build but how do you remove it all together?

keyboard key event

Hi all,

In my design, i should display the individual character which are keyed in by the user into the combobox. lets say user need to key in the word "HELLO" in the combobox. if the user press "H", one message box should show the letter "H". the same way for all other letters. So,

How do i get the individual character which has been keyed in using the keyboard?

Thanks in Advance.

Regards,
Ram

OnKeyDown

r u saying that u can get the key down event in the combobox just by doing like this. the WM_KEYDOWN message goes to the edit control inside the combobox. It cannot be mapped like this from the dialog class, nor from a class drived from CCcomboBox

I believe you havn't read my question carefully!, after reading your discussion with the PP(Problem Poster), i come to know he need to implement that for Combo Box!

When u press a key in the combobox the message actually goes to the edit control inside the combo box. To trap that event u can do like this.

1 Create a member variable for the combobox say m_ComboBox;
2. Now overide the PreTranslateMessage function of the dialog;
3. in that funtion write like this

BOOL CTest::PreTranslateMessage(MSG* pMsg) <br />
{<br />
    if( WM_KEYDOWN == pMsg->message )<br />
    {<br />
        if( ::GetParent( pMsg->hwnd ) == m_combo.m_hWnd )<br />
        {<br />
            TCHAR tcChar[2] = {0};<br />
            tcChar[0] = pMsg->wParam;<br />
            AfxMessageBox( tcChar );<br />
        }<br />
    }<br />
	<br />
	return CDialog::PreTranslateMessage(pMsg);<br />
}

i hope u have created the m_combo variable and mapped the PreTranslateMessage message using the class wizard. isn't it?

did u tried puting breakpoint in the PreTranslateMessage fnuction?

nave

Re: keyboard key event

Ram Murali5-Jul-06 18:55

5-Jul-06 18:55

Ya u r correct. I used breakpoint also. Still i couldnt get the output window. I put breakpoint in OnInitDialog and PreTranslateMessage. once i press debug button, it directly goes to pretanslatemessage function and then goes to the end of the program. since i dun input any char

if( WM_KEYDOWN == pMsg->message ) becomes false. so it goes to the end of the pretanslate function. in this case i can see the minimized window in the taskbar. but i couldnt maximize it. eventually i couldnt see the output window. Frown | :(
