PC-DMIS 2017 (interop.pcdlrn.dll) issue on profile of a surface measurements

Hi,

i am software programer so i dont really know about inspection and CMM.

i am having issue using the library interop.pcdlrn.dll for the command "perimeter scan" for a "profile of surface".

when i'm using the librairy it shows a measurement value of 0 like if the machine is offline. but when i use the software PC-DMIS, i have the good results.

but when i do a "constructed set" for a "profile of surface" i have good results either if im using the library or the software.

i dont't understand how the library can act differently from the software. this strange behavior prevents us to use the custom software on the prod environnment.

because im a software programmer i dont really know how to express myself in this forum so i'm sorry if i dont give enough details

You don't show , and it is rather important how you open the part program. You have to tell PC-DMIS which machine the program should run on (or OFFLINE).
From my own barcode pp starter programmed in Delphi Pascal:
PCD_PartProgram := PCD_PartPrograms.Open(LocalFileName, [COLOR=#0000FF][B]'CMM1'[/B][/COLOR]);
Also, only one PP can have the machine, normally the one you open first. Opening two PP:s in PC-DMIS will open the second one offline, so you need to make sure there are no other PP:s open, before you open the one you want to run.
while (PCD_PartPrograms.Count > 0) do begin
PCD_PartProgram := PCD_Application.ActivePartProgram;
if not VarIsEmpty(PCD_PartProgram) then begin
PCD_PartProgram.Close;
PCD_PartProgram := null;
end
end;

Hi Andersi,
here is the initPCDMIS(...) subroutine:

  private void initPCDMIS(FileInfo tempPrg, out PCDLRN.Application PCDApp, out IPartPrograms PCDPartPrograms, out PartProgram pcdActivePart)
        {
            PCDApp = new PCDLRN.Application(); // fetch the PC-DMIS application
            PCDPartPrograms = PCDApp.PartPrograms; // set up partprograms

            //THE MACHINE IS DEFINED IN App.config. (CMM1 or offline)
            string machine_name = ConfigurationManager.AppSettings["machine"];
            PCDPartPrograms.Open(tempPrg.FullName, machine_name); // have PC-DMIS open the PRG

            pcdActivePart = PCDApp.ActivePartProgram;
            pcdMachine = PCDApp.ActivePartProgram.ActiveMachine;

            Thread.Sleep(100);

            PCDLRN.ExecutionWindow ew = pcdActivePart.GetExecutionWindow(0);

            ew.Top = 1;
            Thread.Sleep(100);
        }
