Got Visual Studio and the Interop.PCDLRN.dll... Now what?

dim app as object
set app = CreateObject("PCDLRN.Application")

// code to open pc-dmis, if pc-dmis is open, this c# application will connect to the currently running instance of PC-DMIS

using PCDLRN;


// class containing functions for interacting with pcdmis
public class PCDMISInterop
{
Appliction pcdApp; // don't use IAppliction, instances of interface types cannot be created, Interfaces can only be inherated

public Application PCDMISApplication
{
get{return this.Application;}
}

public PCDMISInterop()
{
startPCDMIS();
}

bool StartPCDMIS()
{
    try
    {
         Type pcdObjType = Type.GetTypeFromProgID("PCDLRN.Application");
         this.pcdApp = Activator.CreateInstance(pcdObjType);

 pcdApp.WaitUntilReady(60); 
         return true; //pc-dmis started
    }
    catch
    {
         return false; // an error occured
    }
}

// Gets the active part program
}

using PCDLRN;

int main(void)
{
PCDMISInterop PCDMIS = new PCDMISInterop();

PartProgram pcdProgram = PCDMIS.PCDMISApplication.ActivePartProgram

// the following 2 methods could be put into the PCDMISInterop Class to simplify the coding.

// to open a part program
PCDMIS.PCDMISApplication.PartPrograms.Open("C:\test.prg","CMM1"); // "CMM1" for online, "OFFLINE" for offline

// to create a new part program
PCDMIS.PCDMISApplication.PartPrograms.Add("C:\test2.prg",UNITTYPE.INCH/*UNITTYPE.MM for metric*/,"TESTPROBE");


}
