Error In Visio 2007 Drawing Control

[Asif Imran]

Hi all,

An exception is occurred when I am going to use Visio 2007 Active X Drawing
Control in my sample application by adding new page after opening drawing
file in Drawing Control.

I did do the following on my machine running Windows XP Professional
(Service Pack 2), NET Framework 1.1 and Visio 2007 Professional Edition.

a) Run project and open any drawing file. File opens normally.

b) To add new drawing page through Insert Page Form, following exception is
occurred on clicking Insert Page Form's Ok button.
An unhandled exception of type 'System.NullReferenceException' occurred in
system.windows.forms.dll.
Additional information: Object reference not set to an instance of an
object.

c) If I click on Start button (running project in debugging mode through
Visual Studio) another exception is thrown

An unhandled exception of type 'System.Runtime.InteropServices.SEHException'
occurred in system.windows.forms.dll
Additional information: External component has thrown an exception.

Can anyone tell me about whets I am going wrong?

Thanks

Asif

Sample project, drawing file and presentation file (snap shot of
generating error) can also be downloaded in zip format at the following

Have you installed .NET 2 and 3 ? They won't interfere with anything
else.
Also, I see from the Powerpoint slides that you are adding a page to a
cross-functional chart. Try this manually, adding a page shows a
dialog box, is your code interfering with this?

I installed .NET 2 and 3 but it doesn't solve the issue.
I also used other drawing type (basic flow chart) but same error is
still occurring.
There is no even single line of code in application except on button to
assign filename to control source property, so there is no chance for
code interferes.

Yes Christian every thing is going right when manually add a new shape
to drawing but it sounds some bug in Visio 2007 drawing control. Also
one more interesting thing is that if same project is developed in
VS.NET 2005 and do the same steps, different error message is shown:

System.AccessViolationException was unhandled
Message="Attempted to read or write protected memory. This is often an
indication that other memory is corrupt."

Is there some other way to fix the error as it is not like by the
customers to do it to avoid such error?

Thanks

I found some explanation about the error occurred in VS.2005.But there
is no remedy to solve it

Thanks for reporting this. We have determined that it is in fact a bug in
Visio 2007. You can see a description of the workaround here:

We are working to fix the underlying issue as well.
