Win32 API GetPrinter function help

Go to solution

Sounds good. I tried to make a cluster containing the above suggestion for LabVIEW 32 (which is what I am running).

It returns error 116, LabVIEW:  Unflatten or byte stream read operation failed due to corrupt, unexpected, or truncated data.


I created a cluster with LPSTR as strings, unsigned 32 bit for the DWORD data types and Unsigned 32 for the pointers.

I made a simple VI to take the array pointer and convert it to the cluster, attached.

Please read more carefully. ALL the pointer types - anything labeled as LP* or P*, which includes LPSTR - should be represented in the cluster as a pointer-sized integer (32- or 64-bits). Getting any data out of those pointers is complicated, but since you only want the numeric cJobs you shouldn't have to deal with that.

If you are doing this solely to get the number of jobs, you should try .NET:
