Problems with VB .NET

[Jedimaster]

I am trying to learn VB .NET and running into a few snags.

I am running
Windows 7 Professional Service Pack 1 64 Bit
Microsoft Visual Studio Pofessional 2012 Upadte 4
OjectARX 2015
OjectARX 2015 .NET Wizards
AutoCAD MAP 2015

I have refernced in AcDbMgd.dll, AcMgd.dll, Autodesk.AutoCAD.Interop.Common.dll (I have tried both 32 & 64 bit), Autodesk.AutoCAD.Interop.dll(I have tried both 32 & 64 bit).
When tried to drill thru the intellisense ojects like in the demo it stops in certian locations. I tried to manually type in the code it gives me a blue underline and will not complie.

Imports Autodesk.AutoCAD.Interop
Imports Autodesk.AutoCAD.Interop.Common
Public Class AdskCommands
Public ReadOnly Property ThisDrawing() As AcadDocument
Get
**This is what it suppose to look like**
Return Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.AcadDocument
**Here is where it stops**
Return Autodesk.AutoCAD.ApplicationServices.Application.<<STOPS HERE>>
End Get
End Property

**This is what it suppose to look like**
<Autodesk.AutoCAD.Runtime.CommandMethod("myRoutine")>
**Here is where it stops**
<Autodesk.AutoCAD.Runtime.<<STOPS HERE>>
Public Sub myRoutine()
ThisDrawing.Utility.Prompt("Hello World")
End Sub
End Class

Thank you in advance for any advice or help.

I clear the second problem with the Autodesk.AutoCAD.Runtime. Refenced AcCoreMGD.dll and added "Imports Autodesk.AutoCAD.Runtime". I am still getting an error "error BC30456: 'AcadDocument' is not a member of 'Autodesk.AutoCAD.ApplicationServices.Document'." I have tried adding "Imports Autodesk.AutoCAD.ApplicationServices.DocumentExtension"

Replaced

Return Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.AcadDocument

with

Return Application.DocumentManager.MdiActiveDocument.GetAcadDocument()

and added

Imports Autodesk.AutoCAD.ApplicationServices
Imports Autodesk.AutoCAD.ApplicationServices.DocumentExtension

AutoDesk or ADN need to update their documentation. http://download.autodesk.com/media/adn/DevTV_VBA_Migration/english/DevTV_VBA_To_VBdotNet_Migration_E... They are always hounding us to upgrade our software. Maybe if they updated their documentation and fixed known problems we would be more inclined to upgrade.

Hi,

Sorry about the problem you had with the migration material, indeed was designed for our initial migration, but then the API changed...

And I'm glad you're migration from VBA to VB.NET, please let us know if you need further assistance.

I'm experiencing the same issue but mine are not resolved by the suggested fixes which I already had in place.  My code errors on the below lines:

 Dim acDocMgr As DocumentCollection = Application.DocumentManager
        Dim doc As Document = acDocMgr.MdiActiveDocument
        Dim aDoc As AcadDocument
        aDoc = doc.GetAcadDocument()

The error fails on the variable aDoc.  It throws the following error:

'GetAcadDocument()' is not a member of 'Document'.

I have the following imported namespaces as well:

Imports Autodesk.AutoCAD.ApplicationServices
Imports Autodesk.AutoCAD.Runtime
Imports Autodesk.AutoCAD.Interop
Imports Autodesk.AutoCAD.Interop.Common
Imports Autodesk.AutoCAD
Imports Autodesk.AutoCAD.ApplicationServices.DocumentExtension
Imports Autodesk.AutoCAD.ApplicationServices.DocumentCollectionExtension

Any ideas as to what may be causing this?

Thanks.

if you are using AutoCAD 2012 or older, no, you cannot use that line of code  - GetAcadDocument();

If you use AutoCAD 2013 or later, you need to add at least 3 references:

accoremgd.dll

acdbmgd.dll

acmgd.dll

[frosty1_4me]

I do have those 3 references you listed.   The errors appear when attempting to compile the project in VS2015.  Using an older version of VS2013 and it compiles fine without issue.

I'm using 2014 acad map3d and now moving to 2016 map3d.  It's compiled as a 4.0 .net application. 

Perhaps its the version of interop dlls and those other autocad dlls that are causing the issue.  Since I embed the dlls within the .Net project.

Thanks for the response.

[frosty1_4me]

I updated the dll's to use the 2016 installed version and it created more errors as well as continuing with the ones I'm attempting at fixing.  I'd like those fixed before I introduce more.  🙂

I'm having the same problem.  This code worked from VS2012 in ACD2016.  I recently upgraded to VS2015 and now I'm getting the following error:

"

Error	BC30456	'GetAcadDocument' is not a member of 'Document'.	bks_acd2016_01	D:\Visual Studio 2012\Projects\bks_acd2016_01\bks_acd2016_01\AdskCommands.vb	11	Active

Hi,

GetAcadDocument is an extension method defined in the DocumentExtension static class (module in VB).

Using extensions methods with VB is not as comfortable as with C#, e.g. with VB you may need to bring in scope extension methods by 'importing' the module:

Imports Autodesk.AutoCAD.ApplicationServices.DocumentExtension

Then you should be able to call the GetAcadDocument() method as an instance method of the Document type (the extended type)

doc.GetAcadDocument()

Anyway, as extension methods are static methods (Shared in VB), you can also call them with classical way.

DocumentExtension.GetAcadDocument(doc)

[frosty1_4me]

In my code example, I do call the DocumentExtension but I'm still having issues.

Imports Autodesk.AutoCAD.ApplicationServices.DocumentExtension
Imports Autodesk.AutoCAD.ApplicationServices.DocumentCollectionExtension

This Module contains functions that are reference in the project.
    'Some modules can be referenced directly, others are a template to be copied into the required module, and modified.

    Public WithEvents ThisDrawing As Autodesk.AutoCAD.Interop.AcadDocument = Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication.ActiveDocument
    Public WithEvents docs As Autodesk.AutoCAD.ApplicationServices.DocumentCollection = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager
    Public WithEvents acadApp As Autodesk.AutoCAD.Interop.AcadApplication


    Private Sub docs_DocumentActivated(ByVal sender As Object, ByVal e As Autodesk.AutoCAD.ApplicationServices.DocumentCollectionEventArgs) Handles docs.DocumentActivated
        ThisDrawing = e.Document.GetAcadDocument()
    End Sub

The above code fails on the e.Document.GetAcadDocument() as GetAcadDocument not a member of Document.  I've tried ever options for that and still no luck.

Hi,

Sorry but I cannot help very much further.

This topic seems to be very well named, all the thread I read about GetAcadDocument() issues were also related to VB.

It seems to me most of the problems with this method are related to VB specific behavior (extension methods, modules, ...).

What happens if you call the method as a staic (Shared) method.

ThisDrawing = DocumentExtension.GetAcadDocument(e.Document)

[Jedimaster]

Did you add all references in to the project?

[frosty1_4me]

I believe so, unless there is one missing or changed:

- acadbmgd

- Autocad.interop

- Autcad.interop.common

- interop.autocadMap

- ManagedMapAPI

those are the ones in my project.

@frosty1_4me

Aren't accoremgd and acmgd references missing? DocumentExtension is part of acmgd.dll

Maybe this can help:

[frosty1_4me]

My applogies,

Yes, those two are also reference in the project.

I just find it strange this works in VS2013 but not in VS2015.  It's the same project.  In order to trouble shoot the project we are currently rolling back to use 2013 when necessary.  I've checked the target framework as well and it matches 2013 so that is not an issue.

[_gile]

Did you try calling GetAcadDocument() as a static (Shared) method!

ThisDrawing = DocumentExtension.GetAcadDocument(e.Document)

[frosty1_4me]

No, I hadn't tried that!  Ok, I've give that a go and let you know the result.

Thanks!

[frosty1_4me]

That did the trick.  It also set me on a path to correct many other functions that were having similar problems.  Must have been a change to the acad map api from the previous version I was using.

Thanks!
