MDI Active Document isActive = False

Anonymous — Sun, 05 Aug 2018 16:28:26 GMT

Hello

I am developing a code that opens a dwg file,draw something and then close it

then i need to draw something on Active MDI (which was the active before I open the file) but it's IsActive Variable is not set to true?

How can I fix this

Could you provide some code showing what you have so far?

It might be easier to help if we can see what you're doing...

zcBlockDoc = zcDocMngr.Open(BlockPath, True)

zcDocMngr.MdiActiveDocument = zcBlockDoc

With zcBlockDoc
.Database.SaveAs(_RandomName, DwgVersion.Current) ', False)
.CloseAndDiscard()
End With
zcBlockDoc.Dispose()

ZwSoft.ZwCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument = zcOriginalDoc

======================================================================================

This is a snap from the code (it's a long one) ...I need to set the MDIActiveDocument to another file and activate it as in debug mode the property IsActive of MDIActiveDocument is set to flase

It's going to be difficult to help without knowing what's going on in your zc and Zw classes.

Is this run from a command with CommandFlags.Session?

yes I did that

<CommandMethod("SMR", CommandFlags.Session)>
Public Sub SmartInsert()

...Code Mentioned above

End Sub

Friend zcOriginalDoc As Document = Application.DocumentManager.MdiActiveDocument

<CommandMethod("SMR", CommandFlags.Session)>

Public Sub SmartInsert()

Application.SetSystemVariable("SDI", 0)

Application.SetSystemVariable("attdia", 1)

Application.SetSystemVariable("cmdecho", 0)

Dim OpenDwgFileDialog As New System.Windows.Forms.OpenFileDialog()

With OpenDwgFileDialog

.InitialDirectory = EdrivePath

.Filter = "E-drive Block Files |*.Dwg"

.Title = "Select an E-drive Block File....."

.FileName = ""

.RestoreDirectory = True

End With

If OpenDwgFileDialog.ShowDialog = System.Windows.Forms.DialogResult.OK Then

FullEdriveFileName = OpenDwgFileDialog.FileName.ToUpper

zcBlockDoc = zcDocMngr.Open(FullEdriveFileName, True)

zcBlockDoc = ZwSoft.ZwCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument

Else

OpenDwgFileDialog.Dispose()

End If

End Sub

Then we perfume some operations on the file and close it and set the MDI Active document back to the original file

With zcBlockDoc

.Database.SaveAs(_RandomName, DwgVersion.Current) ', False)

.CloseAndDiscard()

End With

zcBlockDoc.Dispose()

ZwSoft.ZwCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument = zcOriginalDoc

The problem appears when trying to insert the zcBlockDoc document as a block in the zcOriginalDoc

In the blow code as the .net environment always finds the zcOriginalDoc Not active

Dim zcInsPntRes As PromptPointResult

Dim zcInsPntOpts As PromptPointOptions = New PromptPointOptions("")

With zcInsPntOpts

.UseBasePoint = False

.Message = vbCrLf & "Specify the insertion point for block :"

End With

zcInsPntRes = zcOriginalDoc.Editor.GetPoint(zcInsPntOpts)

So you're trying to insert a drawing as a block? If that's the case then there are almost certainly examples of how to do that on this forum.

If I'm missing something and you can't use those other methods for whatever reason, then these two lines look a bit suspect to me:

This line I am using to open the block file to do some operations on it

zcBlockDoc = zcDocMngr.Open(FullEdriveFileName, True)

here I am just setting the block file to be the current active document

zcBlockDoc = ZwSoft.ZwCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocumen

Ok after closing the block file

I need to set the MDIActivedocument to be the original file.. how?

Re: MDI Active Document isActive = False

Paulio — Tue, 07 Aug 2018 12:30:46 GMT

Sorry, I'm not really understanding the problem. If you have a drawing open and you then open another, when you close that other drawing, the original one becomes current automatically, no?

Can you not just get the activedocument again after closing the one you opened rather than storing it up front and trying to reuse that?

yes this is the problem the original drawing doesn't become the current automatically...I wish to do that and then

get a point to insert the block from original drawing

Re: MDI Active Document isActive = False

Paulio — Tue, 07 Aug 2018 12:49:37 GMT

So what do you get if you try to get the active document right before you try to get the point? Are you saying that the activedocument is null?

einvalid input

.EditorInput.PromptEditorOptions.InitGet()
.EditorInput.PromptPointOptions.DoIt()
.EditorInput.Editor.DoPrompt(PromptOptions opt)

Re: MDI Active Document isActive = False

Paulio — Tue, 07 Aug 2018 13:09:15 GMT

Sorry, I meant what does the call to MDIActiveDocument give you back?

e.g. Document doc = Application.DocumentManager.MDIActiveDocument.

What is doc at this point? Null?

Re: MDI Active Document isActive = False

Anonymous — Tue, 07 Aug 2018 13:26:00 GMT

No it's not null...it's the document but I still can't get a point on it as it IaActive property is false?

Re: MDI Active Document isActive = False

Anonymous — Tue, 07 Aug 2018 13:30:07 GMT

I need to reset the original document to active?

Re: MDI Active Document isActive = False

Paulio — Tue, 07 Aug 2018 14:34:10 GMT

OK, so you're saying this line:

zcInsPntRes = zcOriginalDoc.Editor.GetPoint(zcInsPntOpts)

is failing, yes?

Forgive me if I'm repeating myself, but have you tried

zcInsPntRes = Application.DocumentManager.MDIActiveDocument.Editor.GetPoint(zcInsPntOpts)

Re: MDI Active Document isActive = False

Anonymous — Tue, 07 Aug 2018 14:53:05 GMT

yes I have tried this

zcInsPntRes = Application.DocumentManager.MDIActiveDocument.Editor.GetPoint(zcInsPntOpts)

and It's Also failing

This works for me. It opens a drawing, saves it out to a different name and then asks the user to specify a point.

        [CommandMethod("TestMethod", CommandFlags.Session)]
        public void TestMethod()
        {
            // Open a file
            Document newDoc = Application.DocumentManager.Open(@"C:\Temp\testDrawing.dwg", false, string.Empty);
            newDoc.Database.SaveAs(@"C:\Temp\testDrawingRenamed.dwg", Autodesk.AutoCAD.DatabaseServices.DwgVersion.Current);
            newDoc.CloseAndDiscard();
            PromptPointOptions pOpts = new PromptPointOptions(string.Empty);
            pOpts.UseBasePoint = false;
            pOpts.Message = "\nSpecify the insertion point for the block :";
            Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
            PromptPointResult res = ed.GetPoint(pOpts);
            ed.WriteMessage($"\n{res.Value.X},{res.Value.Y}");
        }

Result:
