error code 1450 - memory mapped file

[mitulatbati]

Hello,

in my application I am using memory mapped files. I have three of it, the maximum size of the biggest one is 5MB. I store 64 Waveforms from a DAQ card in it. 

The application runs fine, but sometimes comes an error, when I try to access the MMF. The error code is 1450, "insufficient system resources"

Is a size of 5MB too big? Should I rather create one MMF for each waveform?

Hi mitulatbati,

which development tools are you actually using?

Which platform, libraries and so on...?

Can you post example code?

Hi,

I am using LV7.1, and I call some functions from kernel32.dll and user32.dll.

In the meanwhile I figured out, why I get this error message.

I have called the "OpenFileMappingA" function to read/write memory mapped files, but I havent closed the returned handle. So I made a handle-leak in Windows...
