Rename a layout with ObjectDBX (VBA)

[ragarcia]

I need to rename a layout from a .dwg document opened using ObjectDBX library (from Visual Basic for Applications). I tried this:

layout.Name="New name"

where "layout" is the layout object I want to modify.

Then I get an error:

layout does not exist for renaming

I need to do this without opening the file in Autocad. When I execute the same code from inside Autocad, it works perfectly. Maybe it can't be done by using ObjectDBX. Am I right?

Thanks.

Is your layout variable getting set? It would help if you showed the rest of your code so we can see how you're setting the variable.

[ragarcia]

Yes, it is getting set. Here is the whole code:

Set objDbx = GetInterfaceObject("ObjectDBX.AxDbDocument.20")
objDbx.Open "C:\Users\PC\Desktop\Drawing.dwg"
Set lay = objDbx.Layouts.Item(0)
lay.Name = "New name"
Set objDbx = Nothing

It tries to rename the first layout tab as "New name".

If you set a breakpoint and step through your code, what is Layouts(0).Name equal to? It's "Model". You can't rename modelspace.

[ragarcia]

Thanks for the answer, but no. Layouts(0).Name is actually "1". The drawing has 8 layouts, named from "1" to "8" and these names are stored from Layouts(0) to Layouts(7). Layout(8) (the last one, not the first one) is the one that stores "Model".

How did you verify that? I'm pretty sure that Layouts(0) is always modelspace and you can't reorder that. You can add and delete paperspace layouts but the modelspace layout is fixed. Can you post a sample dwg?

[ragarcia]

I can see the value of Layers(0).Name in the debugger. I also used a variable to read it before the error takes place. Remember I said the problem does not happen when I change the layout name in Autocad without using ObjectDBX. I attached 2 files: one with the code and the other with the layouts I wanna change (It has only 2 layouts, but that makes no difference).

I forgot to mention the code is embedded in the Main.dwg file. You can call it from Manage/Run VBA Macro. It's name is layout.

My test shows that layouts are read only via odbx.

[ragarcia]

Thanks a lot for your help. I was afraid it might be so but I wasn't sure and thought there could be another way via ODBX.

I am trying to exactly the same thing (rename layout tabs in multiple drawings via obdx). Is there any other way this can be achieved?

What did you do in the end ragarcia?

as per Ed Jobe tests (see post #9) you can't do that via odbx, since in that context layout object is read-only. thus you can't change any of its properties
