Amit,

This is just a guess, but maybe casting the result to an unsigned Int16
(ushort) might give you the correct number.

Hope this helps.

Hi amit,

I'm really curious, how do you make a control with size 40,000? The size is
limited to 32767 and this limitation comes, as far as I know, from the
Windows OS itself.

Can you post some sample that creates such a huge control?. Then we might
workout something.
