Loop in dialog app...

I've created a dialog window with a modified "static text" which should show how many times a button (C in this case) is pressed by checking it with a WM_KEYDOWN message by using the OnKeyDown()-function. The problem is that nothing is showed on the dialog screen.

Code:

void CTry_5Dlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) 
{
	// TODO: Add your message handler code here and/or call default
	char lsChar;
	lsChar = char(nChar);



	if (lsChar == 'C') {
		m_iCount.Format("%d", count);
		count++;
		UpdateData(FALSE);
	}
	

	
	CDialog::OnKeyDown(nChar, nRepCnt, nFlags);
}

Can anyone explain how I should solve this problem?
