How to switch documents while a command is running

hirano

Hello.

I created a command to get points.

    <CommandMethod("test")>

    Public Shared Sub test()

        Dim editor As Editor = Application.DocumentManager.MdiActiveDocument.Editor

        Dim pop As New PromptPointOptions("Select Point")

        Application.ShowAlertDialog(editor.GetPoint(pop).ToString)

    End Sub

It is not possible to switch documents during user operations.

The "LINE" command allows you to switch documents.（Switching documents will end the command.）

I would like the custom command to be the same as the "LINE" command.

Is there a way to switch documents with a custom command, just like with the "LINE" command?

Usually, you would have to run the command in a session context, Caveat, you may have to add document locks.

Note, if the line command allows for document switching, that seems like a bug

Thank you for your reply.

I tried "CommandFlags.Session", but it didn't solve the problem.

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

    Public Shared Sub test()

        Using docLock As DocumentLock = Bricscad.ApplicationServices.Application.DocumentManager.MdiActiveDocument.LockDocument()

            Dim editor As Editor = Application.DocumentManager.MdiActiveDocument.Editor

            Dim pop As New PromptPointOptions("Select Point")

            Application.ShowAlertDialog(editor.GetPoint(pop).ToString)

        End Using

    End Sub

The problem is occurring in BricsCAD V25.
→BricsCAD version：V25.1.06

As a side note, in V19, custom commands worked the same as the "LINE" command.

I used the "DocumentToBeDeactivated" event but it didn't work.

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

    Public Shared Sub test()

        Using docLock As DocumentLock = Bricscad.ApplicationServices.Application.DocumentManager.MdiActiveDocument.LockDocument()

            Dim editor As Editor = Application.DocumentManager.MdiActiveDocument.Editor

            Dim pop As New PromptPointOptions("Select Point")

            Application.ShowAlertDialog(editor.GetPoint(pop).ToString)

        End Using

    End Sub
    


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

    Public Shared Sub AddDocumentToBeDeactivated()

        AddHandler Bricscad.ApplicationServices.Application.DocumentManager.DocumentToBeDeactivated, AddressOf OnDocDeactivated

    End Sub
    


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

    Public Shared Sub RemoveDocumentToBeDeactivated()

        RemoveHandler Bricscad.ApplicationServices.Application.DocumentManager.DocumentToBeDeactivated, AddressOf OnDocDeactivated

    End Sub
    


    Private Shared Sub OnDocDeactivated(sender As Object, e As DocumentCollectionEventArgs)

        Dim editor As Editor = Application.DocumentManager.MdiActiveDocument.Editor

        editor.WriteMessage(vbLf & "MdiActiveDocument {0}:", New Object() {Application.DocumentManager.MdiActiveDocument.Name})

    End Sub

STEP1: Execute the "AddDocumentToBeDeactivated" command.

STEP2: Execute the "test" command.

STEP3: I try to switch drawings during the "GetPoint" operation.

RESULT: The drawing does not switch. The "DocumentToBeDeactivated" event does not occur.

It looks like drawing switching is disabled. Is there a way to enable drawing switching?

I'm really in trouble.

Do you have any information?

Sorry, it seems CAD is becoming stricter with document switching. The only way I’ve found that works is to use the document manager to switch documents.

@Ap.Command("doit", Ap.CmdFlags.SESSION  )
def doit() -> None:
    try:
        man = Ap.DocManager()
        docs = man.documents()
        man.setCurDocument(docs[0],Ap.DocLockMode.kNone,True)
        print(docs[0].fileName())
        ps, pnt1 = Ed.Editor.getPoint("\nSelect Point")
        
        man.setCurDocument(docs[1],Ap.DocLockMode.kNone,True)
        print(docs[1].fileName())
        ps, pnt2 = Ed.Editor.getPoint("\nSelect Next Point")

    except Exception as err:
        traceback.print_exception(err)

: DOIT

Drawing1.dwg
Select Point
Drawing2.dwg
Select Next Point

Thanks for your reply.

However, that wasn't what I wanted.

I did some further research.

I was able to achieve what I wanted using "BRXSDK."

It seems this isn't possible with ".NetAPI."

Please let me know if you have any additional information.
