Hi all,

I would appreciate your help on this topic. I have a DLL function that looks like this GetCurrentFrame(int CamHandle, int FrameType, BYTE *Buffer), and it returns a very large buffer for a 1.3MPix image. The image is structured in a 1-D array of BGR bytes all sequential. So the total array size is 1280x1024*3=3,932,160 byte elements.

I tried redim myBuff(0 to 3932159) this works fine in VB. When I try

Global ImgSize as long

ImgSize = (1024*1280*3)

The VB6 compiler complains for overflow; the answer is too big and does not fit. It should fit up to 2 billion, why is VB complaining ? Does any one know how to solve this problem?

Regards,

Try ImgSize = (1024& * 1280 * 3)

And if that doesnt do it

ImgSize = CLng(1280 * 3) * 1024

Thanks I figured it out too. It wants
ImgSize = 1280& * 1024& * 3&

This is so weird I have experienced that error before in all these year using VB6. Anyway, thanks for the response
