error 1097 after calling dll function which allocates memory inside

[Tomzi]

Thank you for your quick answer.

Yes, i am sure that the Allocate function cause the problem because all other function which only making register reading or writing works well, and i also tried an another function

which uses Allocate function as well but first calls an another function which writes some registers and i can see that function succeeds and the Allocate crashes.

I think i can get the source code for that function and i can post it here.

Best regards,

Problem solved.

I was a bit stupid because of some performance issues i should have add my user to Lock Pages Priviliges. That caused the error so now the LabVIEW application runs withour error.

Thank you and sorry for wasting my time.
