Thanks for your suggestion but as far as i concern it is really a VB.net problem cuz i can't run my project.
This error appears while i try to compile my project then it will force me to close the IDE.
The size of my project is around 110 MB(Froms + Modules + Classes) and i got 2GB RAM in my machine that should do the job right?
>>"Separate in different DLL "
It seems to me that you should create DLL's from the Modules and Classes and use the DLL's to run your app from.
I have not worked with DLL's in projects, created a few samples, though I do believe that you add them as a Reference to the project.
