Windows GUI doesn't provide such a information, because it supports proportional fonts. Only if you have a monospaced font then you may compute rows and cols values using functions like GetWindowRect[^] and, for instance, GetTextExtentPoint32[^].

i have been trying like below but even then it is not working.

case WM_CHAR:
iMaxRows = LOWORD( lParam );
iMaxCols = HIWORD( lParam );
hdc = GetDC( hwnd );
szBuffer[0] = wParam;
SelectObject (hdc, CreateFont (0, 8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, FIXED_PITCH, NULL)) ;
TextOut( hdc, ixChar * x++, iyChar * y, szBuffer, lstrlen( szBuffer ) );
if( x == iMaxRows )
{
x = 0;
y++;
}

ReleaseDC( hwnd, hdc );

Why is it supposed to work? I mean lParam of WM_CHAR message does NOT contain the info you are trying to extract from.

i read in some blogs which say like LOWORD of lparam gives max cols and hiword of lparam gives max rows. :(

Please stop reading blogs, read the documentation instead.

Good point, a 5. Generally, a whole approach is so wrong...
