WIN API & C#

[MaxBici]

In c# ,
I use wmi to monitor print job but I need to get PrintJob 's number of
copies and wmi don't expose it.
So i think to use win API but I am a newbie of Pinvoke.
This is function declaration:
[DllImport("wins pool.drv", EntryPoint="Get Job")] public static extern int
GetJobA
(int hPrinter, int JobId, int Level, ref byte pJob, int cdBuf, ref int
pcbNeeded)

Anyone can help me , any example to use this function?
Thanks in advance
Max

Hi Max,

You should take a look at

http://www.pinvoke.net/

I couldn't find an entry for GetJob, but assuming your pJob returns an array of job structures, you can either read the array by hand or use Marshalling for transforming the byte[] -> Job struct
