What purpose you post the code for? Any question?

Without knowing what issue you may have, one thing is immediately caught in my eyes: why do you call Document.SebdStringToExecute() to call a command "CANCELCOMMANDVBNET" during a Transaction. No matter what that command does, it is bad thing to call SendStringToExecute() during a Transaction.

@norman.yuan First of all thanks for reply.

Question is I want to display block attributes on palette whenever user selects block, I added ed.selectionadded event for that.

everything is good but textbox does not show anything.

Command you were talking about is for cancelling selection, I am new programmer , I will try to remove that from within transaction.

Thanks,

Pankaj

Hi,

To cancel a selection, you'd rather use the Editor.SetImpliedSelection() method passing it a null or empty ObjectId array.

@_gile thanks for reply it helped.

I am facing another problem now I added ed.selectionadded event handler but I am not able to remove it.

I posted below problem in different post but in case if yu can help!

I am using below eventhandler to add e.selectionadded event

AddHandler ed.SelectionAdded, AddressOf testit

And I am using below statement to remove it.

RemoveHandler ed.SelectionAdded, AddressOf testit

But it does not get removed.

My testit function,

Public viewmodel As New GetATT_ViewModel
 Public Sub testit(sender As Object, e As SelectionAddedEventArgs)
        Dim objectid() As ObjectId = e.AddedObjects.GetObjectIds

        viewmodel.getattribute(objectid)


    End Sub

I read somewhere that you need to make function shared but I can not make that as I am calling another function in it which is not shared.
