Contour GetGraphicItemByName, GetGraphicItemByType exceptions in all cases - C# automation

I'm trying to automate the capture of JMP graph images through C#.  From what I found through the documentation, the correct way to do this appears to be by getting a handle of the graph with GetGraphicItemByName or GetGraphicItemByType and then SaveGraphicItem.


I found some guidance from this previous post on the subject:

Specifically, this reply on proper use of it (the documentation is really lacking on this otherwise)


However... it doesn't work for anything I have tried.  Everything throws the same unhelpful error which appears to be a native level exception in JMP:

The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))


I've tried with both varieties of ByType and ByName using several different objects within the tree.  I feel like I must be missing something but I don't know what it could be as the error doesn't give me the slightest clue what is wrong.


            JMP.Contour contour = Doc.CreateContourPlot();

            int handle = -1;
            string errors = string.Empty;

            for (int n = 0; n < 11; n++)
                string name = "outline box";

                switch (n)
                    case 1: name = "outlinebox"; break;
                    case 2: name = "Outline Box"; break;
                    case 3: name = "Outline box"; break;
                    case 4: name = "outline box"; break;
                    case 5: name = "framebox"; break;
                    case 6: name = "FrameBox"; break;
                    case 7: name = "Frame Box"; break;
                    case 8: name = "frame box"; break;
                    case 9: name = "Frame box"; break;
                    case 10: name = "Framebox"; break;

                    handle = contour.GetGraphicItemByType(name, 1);
                    //handle = contour.GetGraphicItemByName(name);
                    Console.WriteLine("Success with n = " + n);
                catch (Exception e)
                    errors += e.Message + Environment.NewLine;
            if (handle == -1) throw new Exception("No handle found, errors: " + Environment.NewLine + errors);

Re: Contour GetGraphicItemByName, GetGraphicItemByType exceptions in all cases - C# automation

I resolved the issue.  Turns out the error was elsewhere in my code.  I'm unsure why it threw the error that it did though.  The table I provided it didn't have the columns that I expected it to due to another bug in my code.  I would have expected that JMP should have caught such a simple error and thrown a more relevant exception which is why I assumed an issue with the function itself. 


If anyone else comes across this with a similar issue, be sure to check all other aspect of your input as you can't rely on JMP to report back a meaningful exception...
