Topic: GetSystemVariable from a CommandMethod.Session

[Odoshi]

Hi,

GetSystemVariable is not returning anything when CommandMethod is Session. Works for CommandMethod Modal.

Is this the correct behavior? The command does a lot, including opening several drawings, calling SetSystemVariable as well as running LISP from Application.Invoke.

Currently it is failing on:

Dim doc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Add("C:\my-tplate.dwt")

Any suggestions on the CommandMethod flags to use?

Thanks,
Mike

OK, here's what it was:

Calling Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(frm)

Better to just use frm.ShowDialog()

Thanks,

Just to follow up,

SetSystemVariable does not seem to be working when CommandFlag is Session. Could anyone else confirm?


Thanks,
Mike

Yes,
I get Autodesk.AutoCAD.Runtime.Exception: eInvalidInput when using SetSystemVariable from a Session ie TestS1.

I don't have an issue with GetVariable ... what are you trying to do ?

using:

Code - Text: [Select]

1. using Autodesk.AutoCAD.Runtime;
2. using Autodesk.AutoCAD.ApplicationServices;
3.  
4. [assembly: CommandClass(typeof(SetVariableTester.MyCommands))]
5.  
6. namespace SetVariableTester
7. {
8.     public class MyCommands
9.     {
10.         [CommandMethod("TestD1") ]
11.         public void MyDocumentCmd1()
12.         {
13.             Application.SetSystemVariable("CLAYER", "0");
14.         }
15.         [CommandMethod("TestS1", CommandFlags.Session)]
16.         public void MySessionCmd1()
17.         {
18.             Application.SetSystemVariable("CLAYER", "0");
19.         }
20.         [CommandMethod("TestS2",  CommandFlags.Session)]
21.         public void MySessionCmd2()
22.         {
23.             Application.ShowAlertDialog(Application.TryGetSystemVariable("CLAYER").ToString());
24.         }
25.     }
26. }

Which variable are you trying to set ??
Some can be set using properties of the Database for the ActiveDocument
eg:

Code - C#: [Select]

1. Application.DocumentManager.MdiActiveDocument.Database.Orthomode = true;

Some of your post has nothing to do with SystemVariables .... you may need to clarify what you want.

How is it failing ?
What is the exception ?

I've done away with the Session flag, so that's no longer an issue.

I also moved to a palette, so DocumentManager.Add is now working.

Thanks for the replies,
Mike
