VK_BACK is not working when button is clicked [Solved]

[ShilpiP]

Hi All, I am working on one application where i use an edit control and on button click i just want to delete the text of edit box using VK_BACK. my code is

HWND hWnd = NULL;
hWnd = ::GetDlgItem(m\_hWnd, IDC\_EDIT);
::SendMessage(hWnd, WM\_KEYDOWN, (WPARAM)0, (LPARAM)VK\_BACK);

Thanks in advance. :)

Perhaps the Edit control is coded to respond to WM_KEYUP rather than WM_KEYDOWN, or maybe these are ignored in favour of WM_CHAR. It's possible, although unlikely, that you might need to send all 3 in the right order. If none of that works you'll need to do a GetText and something to get the cursor position, remove a character yourself and do a SetText to put the modified text back.

Is using VK_BACK a constraint?

Since you want to delete the text in the edit box why don't you simply use SetWindowText(/*windowhandle*/,"").

Somethings seem HARD to do, until we know how to do them. ;-)_AnShUmAn_

No because my main concern is to delete the text of edit box using VK_BACK when i click the button.

This should work then.

::SendMessage (hwndEdit,WM_CHAR,(WPARAM)VK_BACK,(LPARAM)1);

Rate it if this helps
