"Method not found" when using Visio.Shape.Picture property

[B.Molsbeck]

Hello,

I am developing an addin for Microsoft Visio 2003. One of the functions
of the addin shows a modal dialog with a picturebox. In that picturebox
I need to show a visual representation of a shape of the Visio
document.

I use the following code to retrieve and show the picture:

Dim theDocument As Microsoft.Office.Interop.Visio.Document =
Application.ActiveDocument
For Each thePage As Microsoft.Office.Interop.Visio.Page In
theDocument.Pages
For Each theShape As Microsoft.Office.Interop.Visio.Shape In
thePage.Shapes
Dim thePicture As stdole.IPictureDisp = theShape.Picture
Dim theShapeMetafile As System.Drawing.Imaging.Metafile = _
New System.Drawing.Imaging.Metafile(New IntPtr(thePicture.Handle),
False)
thePictureBox.Image = theShapeMetafile
....

But on the 4th line ("theShape.Picture") I receive the following error:
"Method not found: Microsoft.Office.Interop.Visio.Shape.get_Picture()"

What am I doing wrong? Does anybody know a different way to retrieve
the picture of a shape?

Thanks in advance for your help!

Visio shape has Picture property but has not Get_Picture method.
You might check again your code.

I am using the Picture property, but I think that the interop
internally uses the get_Picture() method, which causes the error.

Now, I have the same error with you.
This is not the case in VBA.
I wonder something is missing, or bug in Visual Basic .Net.

 

[B.Molsbeck]

Is there a way to check for this error in code? Because when I use the
common Try...Catch construction, it does compile correctly. But when
the application runs, the JIT-Debugger is activated on that line of
code. I would like to prevent that to happen.

I found the reason what caused the error:
Microsoft Visio was incorrect installed. When I removed it completely
from the system and reinstalled it with the default options, the code
works perfectly!

Congratulations! But please tell us what was incorrect in instalation.

 

[B.Molsbeck]

Sorry, I do not know what was incorrect or missing with my Visio
installation.

As a last resort, I just removed and reinstalled Visio to verify that
my installation did not cause the problem. And what do you know: it
did!

Unfortunately, I cannot spend more time to investigate the corrupt
Visio installation. The important thing is that my problem is solved
and that it was not caused by my .NET code.
