Hi,MapViewOfFile Fails only when ur application continuously do that or systems virtual memory is low.Is ur application continuously doing MapViewOfFile?.If u r doing so u have to ummap the previous Mapped views using UnMapViewOfFile.But u can use the same handle which u got from CreateFileMapping/OpenFileMapping api. regards Vairavan

You're probably trying to map a file that's larger than the largest block of contiguous free address space in your process. For example, trying to map a 2GB file in one go will always fail on a 32-bit system. Map the file a smaller piece at a time.

Stability. What an interesting concept. -- Chris Maunder

First of all, thanks for the reply. Application is not continously using MapViewOfFile. Probably what I feel that systems virtual memory is low which is causing the failure.

Thanks for the help. Even I feel the same..Probably trying to map a file that's larger than the largest block of contiguos free address space is causing the failure. But the problem is that it is not continous. Sometime problem comes when trying to map 32MB of memory and sometimes 80MB of memory. So I am not able to come to a conclusion and what should I try?
