Topic: AutoCAD Map3D Crashing on SetPlotConfigurationName

[autogis]

Autocad is blowing up when SetPlotConfigurationName is called from a NETLOADed dll.  The problem is happening on a specific machine.   Also if I import that machines's settings onto my developer machine (using the import/export AutoCAD 2012 settings), I still cannot replicate the problem.  The code works correctly on my machine with the imported settings from the failing machine.  Here is the pertaining code:

string device = "Default Windows System Printer.pc3";
string NewLayoutName = "NewLayout";

LayoutManager layoutMgr = LayoutManager.Current;
layoutMgr.CurrentLayout = "Model";
                // Printer
                ObjectId layoutId_printer = layoutMgr.CreateLayout(NewLayoutName);
                using (Transaction t = db.TransactionManager.StartTransaction())
                {
                    PlotSettings ps = (PlotSettings)t.GetObject(layoutId_printer, OpenMode.ForWrite);
                    PlotSettingsValidator psv = Autodesk.AutoCAD.DatabaseServices.PlotSettingsValidator.Current;
                    psv.RefreshLists(ps);
                    // Set the device
                    psv.SetPlotConfigurationName(ps, device, null);  // <<< THIS LINE IS CRASHING


Attached is the Error.  The exception number can vary, it is not a fixed error number.  Also, the code does have a try/catch but it is not catching this error, AutoCAD is just crashing.

Problem Fixed:

I performed the following on the problem machine and the problem was fixed:

1. Open AutoCAD Map3D 2012
2. Left Click on Layout1 to select it. (Or any other layout)
3. Right Click on Layout1 and choose "Plot..."
4. Under "Printer/Plotter Name", choose "Default Windows System Printer.pc3".  It took about 30-40 seconds to select the printer. (In comparison to selecting the others which was right away)
5. The printer was not selected, it just showed a blank selection.
6. Click on Cancel to close the "Plot..." window
7. Right Click on Layout1 and choose "Plot..." again.
8. Under "Printer/Plotter Name", choose "Default Windows System Printer.pc3" again.  Again it took about 30-40 seconds to select the printer.
9. This time "Default Windows System Printer.pc3" stayed selected.  Click the "Ok" button.
10. Close autocad, open autocad, and now do a netload, run your dll, run your commands etc., as usual...

Problem was gone!
