SetJob Acces_denied

[Cedric]

Hello,
I'm trying to use The SetJob API so for testing purpose I call Getjob to
retreive a valid structure JOB_INFO_2 And then I call SetJob with the same
structure.

But result of SetJob is an Error 5 : ACCESS_DENIED. I don't understand
because I'm PC's Administrator, my printer is local, I use OpenPrinter with
desiredAccess set to PRINTER_ALL_ACCESS.

I red something about the value of JOB_INFO_2's member SecurityDescriptor
that must be set to null before calling SetJob but is already set to null.

Thanks For Help.

I suspect the access denied refers to the job, not the printer. How are you
obtaining the job id?

Hello,

I pause the printer and print test page.

After that, to get jobId I first test EnumJob's sample found in msdn. So I
retreive all jobid.

And now I try to change job properties with SetJob.

AFAIK you can't do this. SetJob, when setting properties, has to be done
when the job is created. Once you've created the job, you can't alter all of
its properties. You will need to strip out all of properties that you may
not alter.

Hello, thanks for that . It's working when I just copy few members.

But another question about the array's size. In fact, the array's size
return by the GetJob is bigger than size return by Marshal.Sizeof(Structure),
Why ?

It's seems that the array must be big enough to store all string, but if I
modify string how to calculate size needed ?

Thanks

Marshal.Sizeof(Structure)

Isn't this VB.NET? If so, please ignore all of my posts, as they are for VB6
only and are inapplicable in your case. Moreover, I have no idea how to
solve your issue if it's for VB.NET. Furthermore I cannot answer your
question regarding Marshal.Sizeof(Structure).

For VB6, the answer is that the array size (byte count) is returned by
GetJob in pcbNeeded.
