Error CS1525

Hi,
I use an external Dll that works well if tried in run mode:
prdll.PRCE_SetupPrinter(15,9,4,0,0)

When I compile program I have this error:



All 5 parameters are correct.
In run mode, this DLL run fine and perform well.
Where is the error?
Thank you in advance:sign0148:

Hi, sometime some library doesn't work with Basic4PPC, maybe this lib must be use with VS or an other compiler...
Can you upload your source code + dll?
