AccessViolationException - Trying to print

Question

Hi All,

I am trying to print a report from Reporting Services, the approach I am taking is:

Render the report to get the Byte[] Create a file in the client (Something.pdf) Load that file in Read Mode to a FileStream Then I try to make a call to the procedures described in http://support.microsoft.com/kb/322091/en-us

If you in method SendBytesToPrinter, there is a line: bSuccess = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);

This line gives me the AccessVilationException.

Does anyone know how to solve this, and is there any better way of doing this?

Thanks in advance

Answer 1

You have memory allocation/manipulation problems, problably when allocating memory for the pBytes array. See http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/cf744c83-fd7e-434c-b160-3f076d7491bf for a similar problem that is solved in that thread.

I have given up on this one, but thanks for those that tried to help.
