to display data

[Guest_imported]

Hi,
I must make a MDI application based on CEditView.
This application use files with binary data just '0' and '1'.
When the user presses another key which '0' and '1', I would like that the data don't display in the window.
the data are just displaing when it's '0' or '1'.
if someone can help me, it's cool.
thanks

override the WM_CHAR message handler into your view class, modify the code as follows. You get it!
void CTestSDIView::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if (nChar == '0' || nChar == '1')
CEditView::OnChar(nChar, nRepCnt, nFlags);
}

Thanks, it works !!
But i have another problem, I need the keys BACKSPACE and RETURN.
For these keys '->' '<-' 'Ctrl' 'Shift' 'Alt' , I have found in the &quot;Key Scan Codes&quot; in the MSDN but I don't know for RETURN and BACKSPACE

Thanks

check the virtual-code of MSDN, return and backspace should be VK_RETURN and VK_BACK.
