HDC Device Context Value

Question

Hello Everybody.
Maybe this is not the right forum but I have big problems finding information about this issue. Maybe someone can give me some hints or information.
Problem:
I'm integrating a 3rd-party VB-based Prinout-application with JAVA. I have c-wrappers (JACOZOOM) for this application and the work very good. However the printout method takes Printer.hDC as an argument when starting the printout. The VB Printer function is located in VB6.OLB and is not included in the wrapper. So far I have understood the hDC is something lika a "hardware Device Context" or a handle or something like that and is a reference to a printerjob(?).
Question:
Is there some way in JAVA to access the value that corresponds to the Printer.hDC in Windows? In that case I would like to pass this value along to the the method-call of the wrapper. Is there some information about this anywhere on the web. Maybe there Is a better (more simple) solution to do this.

Excuse me for my vague formulation of this problem. I neither a Java, VB or C++ expert. Just trying. :-)

There is a sneaky way to get the hDC.
import sun.awt.windows.WPrinterJob;
class WinPrinterJob extends WPrinterJob{
     WinPrinterJob(){
     public int getDC(){
          return getPrintDC();
}//class WinPrinterJob
class WrapJob {
     WrapJob(){}
     public PrinterJob getPrinterJob(){
          return new WinPrinterJob();
}//WrapJob
WrapJob wrapJob = new WrapJob();
PrinterJob pj=wrapJob.getPrinterJob();
//show print dialog etc...
int hDC = ((WinPrinterJob)pj).getDC();Now this is no longer a Java question, but does anyone know how to get to the DEVMODE structure given the hDC? I have to use JDK1.3 and PrinterJob (not PrintJob), and want to set the printer resolution using as little native code as possible.
Thanks.
