Topic: Can't set active drawing for it's modify.

[Andrey Bushman]

AutoCAD 2009 SP3 x86 Enu,
MS Visual Studio 2010,
Windows XP x86 SP3 Rus,
.Net Framework 3.5 SP1 x86
=======================

Why I get mistake (look code comments)?

Code: [Select]

   public class Class1
    {
        [CommandMethod("q5", [color=red]CommandFlags.Session[/color])]
        public void q5()
        {
            //Remember current drawing
            Document dwg = acad.DocumentManager.MdiActiveDocument;  
          
            //Drawing for edition
            string fileName = @"C:\Documents and Settings\andrey.bushman\My Documents\Drawing1++.dwg";
            
            //Open drawing
            Document dwg2 = acad.DocumentManager.Open(fileName); //[color=red]Instance not null![/color]
          
            //set current drawing
            acad.DocumentManager.MdiActiveDocument = dwg2;//[color=red]HERE I GET ERROR: eInvalidInput - WHY???...[/color]

            //Modify drawing
            dwg[color=red]2[/color].SendStringToExecute("_circle 0,0 50 _zoom _all ", true, [color=red]false[/color], true);

            //Restore active drawing
            acad.DocumentManager.MdiActiveDocument = dwg;

            //Save & Close drawing
            dwg2.CloseAndSave(fileName);
        }
    }

Will work it:

Code: [Select]

           
if (acad. DocumentManager. MdiActiveDocument! = dwg2)
{
   acad. DocumentManager. MdiActiveDocument = dwg2;
}And it:

Code: [Select]

((AcadDocument) dwg2.AcadDocument).Activate ();
It is strange that in the first variant mandatory check is required...

The subject is closed.

Just for interest, are you able to draw a circle in dwg2 and save it ??

[Andrey Bushman]

Just for interest, are you able to draw a circle in dwg2 and save it ??

It does not turn out yet (((

[Andrey Bushman]

It work:

Code: [Select]

        [CommandMethod("q5", CommandFlags.Session)]
        public void q5()
        {           
            Document dwg = acad.DocumentManager.MdiActiveDocument;
             
            string fileName = @"C:\Documents and Settings\andrey.bushman\My Documents\Drawing1++.dwg";             
            Document dwg2 = acad.DocumentManager.Open(fileName, false); //Полученный объект не равен null, т.о. его можно использовать далее.
           
            if (acad.DocumentManager.MdiActiveDocument != dwg2)
            {
                acad.DocumentManager.MdiActiveDocument = dwg2;
            }           
           
            ((AcadDocument)dwg2.AcadDocument).SendCommand("_circle 0,0 50 _zoom _all ");
           
            dwg2.CloseAndSave(fileName);

            if (acad.DocumentManager.MdiActiveDocument != dwg)
            {
                acad.DocumentManager.MdiActiveDocument = dwg;
            }         
        }
When I will open a file "Drawing1++.dwg" - I see a circle.

Are you using mixed COM and wrapped ARX now ??


I see that you've changed the first post ... that is really confusing.

It helps for anyone following later if you nominate your references ie ..
where does AcadDocument come from.
((AcadDocument)dwg2.AcadDocument).SendCommand("_circle 0,0 50 _zoom _all ");

Anyone who copies this and tries to see how it works will have trouble .. better to explain now

and I see that SendStringToExecute is now SendCommand


I'm happy that you're happy with it working

[Andrey Bushman]

I see that SendStringToExecute is now SendCommand

SendStringToExecute it's Document's method - not draw circle in my code
SendCommand it's AcadDocument's method - successfully draw circle in my code

[Kerry]

Yes, I understand.
