Problem with 'Delete' key.
-
Hi All, I am developing a 'Text editor' kind of application. I have derived a class from 'CView' and i am doing all text editor relevant operations with this. If i select some text and if i press 'Delete' button then my tool is deleting the selected text. But if i do the same thing without selecting the text then it is not deleting the characters. :doh: That means without selecting some text delete operation is not working... :(( Can any one please tell me how can i handle this ??? :zzz: Thanks & Regards Sanjeeva Kumar :rose:

Hi Shashi, Yes. cursor is focused in test editor. I think i have not written code for handling the delete key event. Please tell me if you know how to handle this ??? Thanks in advance Sanjeeva Kumar.

But did you not earlier state that, "If i select some text and if i press 'Delete' button then my tool is deleting the selected text."? In your deletion code, are you first checking to see if any text is selected?

I think u don't need to override the WM_KEYDOWN message. it will all happen automatically. or if u need to override for some reason then call base implementation in overridden function eg: If you are using the CEdit then you need to call the CEdit::OnKeyDown in ON_WM_KEYDOWN Message Handler function. Or if you are using a Win32 then u need call the Old Window procedure in your own window proc. i mean leave the deleting to the default message handler. that's it. BEGIN_MESSAGE_MAP(CMyEdit, CEdit) ON_WM_KEYDOWN(OnMyEditeyDown) END_MESSAGE_MAP() void CMyEdit::OnMyEditeyDown( UINT nChar, UINT nRepCnt, UINT nFlags ) { CEdit::OnKeyDown(nChar,nRepCnt,nFlags); // to Do } i think this will help you

I have written code for deleting characters only if some text is selected. If i simply press the 'Delete' button then this function is not invoked. do i need to handle it separately ??? Regards, Sanjeeva Kumar.

I would think so.
