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

Hi Don,

See the attached file " samplecode.txt " this is the c# code i'm using to execute the .prg file:

private void runProgram()
        {
            foreach (var process in Process.GetProcessesByName("PCDLRN"))
            {
                process.Kill();
            }
            Thread.Sleep(1000);

            //COPYING .PRG AND .CAD FILE FROM NETWORK FOLDER TO A LOCAL FOLDER (c:\\TEMPCMM\\)
            themodel.Instance.statusBar = string.Format("PROGRAM DOWNLOADING ...");
            FileInfo tempPrg = new FileInfo(themodel.Instance.programPath);
            FileInfo tempCad = new FileInfo(themodel.Instance.cadPath);
            FileInfo reportPath = new FileInfo(themodel.Instance.reportPath);

            DirectoryInfo tempFolder = new DirectoryInfo("c:\\TEMPCMM\\");

            if (!Directory.Exists(tempFolder.FullName))
            {
                Directory.CreateDirectory(tempFolder.FullName);
            }

            File.Copy(tempPrg.FullName, Path.Combine(tempFolder.FullName, tempPrg.Name), true);
            File.Copy(tempCad.FullName, Path.Combine(tempFolder.FullName, tempCad.Name), true);

for the library INTEROP.PCDLRN.DLL, i'm using v12.2.0.0, you can see attached file "dll_version.PNG" for more details

for the software PC-DMIS 2017 R2 64-bit, i'm using the build #1260, you can see attached file "software_version.PNG" for more details.

for the moment i cannot upload the .PRG file.

A "perimeter scan" for a "profile of surface" generated from the custom program:

A "perimeter scan" for a "profile of surface" generated from the software:

to solve the probleme, the first things i am wondering is:

what are all the temporary files generated by the program for ?
do i correctly open and close pc-dmis from my c# program ?
is there possibility of mismatch between dll version and sotware version ?
