VB .NET Select Existing Table and Read Data

[katarakt]

I'm trying to convert my existing VBA application to .NET.  The VBA app prompted the user for the selection of the table (a two column table), would read the data, and input it as custom sheetset properties.  I've struggled through the learning curve of importing, running, etc. in the .NET world, but I'm stuck.  The error is somewhere between the reading of the table and passing that information into the sub to insert it into the sheetset manager.  I'm using Win 64bit and Autocad 2013.  Any advice is appreciated.  Code:

Ok, so I've made some progress.  My problem was in my array declaration/initialization.  I know there are better data structures than arrays, but this is such a simple routine I don't want to learn more than I have to to convert this from VBA 🙂

I now seem to have a different problem.  My program will write the data (I think) to the sheetset.  It's very ungraceful (right now it opens and closes the sheetset database for each value - takes a lot of time).  But I have a weird problem.  When I hover over the sheetset and get the pop-up preview, I see the custom values (image attached).  But when I right-click on the sheetset and edit the custom properties, there are none.  Any ideas about this?

Any help is appreciated.

Hi,

In the sample code that you shared, I dont get the two subs called "CUSTOM_SHEETSET_PROP" and "ssdata" ? What are those methods for ?

Here is a test code mostly based on what you had posted that works ok and it adds a few custom properties to the sheetset. Maybe this helps you spot the actual error in your code.

        Public ReadOnly Property ThisDrawing() As AcadDocument
            Get
                Dim doc As Document = Application.DocumentManager.MdiActiveDocument
                Dim acadDoc As AcadDocument = TryCast(doc.AcadDocument, AcadDocument)
                Return acadDoc
            End Get
        End Property

        <CommandMethod("TestApp")> _
        Public Sub SelectTable()

            'On Error GoTo MyError
            Dim tblObj As AcadTable
            Dim tblPt As Object

            Dim sheetsetCount As Integer
            Dim iterDb As IAcSmEnumDatabase
            Dim ItemDb As IAcSmPersist

            sheetSetMgr = New AcSmSheetSetMgr

            iterDb = sheetSetMgr.GetDatabaseEnumerator
            ItemDb = iterDb.Next
            sheetsetCount = 0
            Do While Not ItemDb Is Nothing
                sheetsetCount = sheetsetCount + 1
                ItemDb = iterDb.Next
            Loop

            If sheetsetCount > 1 Then
                MsgBox("There are multiple Sheet Sets Open." & Chr(10) & "You must close all other Sheet Sets.")
                Exit Sub

            ElseIf sheetsetCount = 0 Then
                MsgBox("There is no open Sheet Set." & Chr(10) & "Data was NOT updated.")
                Exit Sub
            End If

                sheetdb.UnlockDb(sheetdb)
            End If
        End Sub

 This code inserts a few test values as custom properties and does not use the value from the table. But it should be straight forward to change that to use the values from the table.

Also the way you handle the array is a bit messy and it would help if you use a "System.Collections.Specialized.StringCollection" instead of the array.
