Hi,

I have created my own cut/copy/paste for visio. 

Sometimes, when I try to cut a selection the entire application hangs and I 
have to close it and restart. 

This is the code I use: 

Selection cutCopyPasteSelection = null;
this.cutCopyPasteSelection = visioCtl.Window.Selection;
this.cutCopyPasteSelection.Cut(VisCutCopyPasteCodes.visCopyPasteNormal);

Sometimes this code does work, so it doesn't always hang.  Am I doing the 
cut wrong? I copied the code from the sample in the documentation.

Thank you.

Sorry, I posted the wrong code. It is not a Cut() that is hanging the visio 
document. Those seem to work fine. It is instead the Copy() that hangs visio.

Selection cutCopyPasteSelection = null;
this.cutCopyPasteSelection = visioCtl.Window.Selection;
this.cutCopyPasteSelection.Copy(VisCutCopyPasteCodes.visCopyPasteNormal);

this may not be the solution to what is happening, but, when I had a similar 
problem I observed that it appeared to be the number of objects in the 
selection that was causing the hang. The workaround was to create a group of 
the selections before attempting the paste of the group.

Do you think this is the same problem eventhough I have only one shape 
selected? Is there a way to create a group of selections from on shape?

Thanks

If it's only a single shape I doubt that it is the same problem. I ran into 
it when the shape count got around 50 shapes. Do you have your code wrapped 
with error trapping (try-catch-end try, on error, whatever) to catch what 
might be failing?

It is quite odd behavior and I am unsure how to track it down since it is 
after I make a call to the visio code. 

I did put a try-catch block around the code today just to catch anything 
that might fall out in the future but I don't think that was the problem. 
Before, I was just walking/stepping through the code one line at a time in 
the debugger. I had actually set a beakpoint right before the .Paste() and 
then tried to walk over the .Paste() line and that is when the whole 
application locks up.

Today, I removed all breakpoints and just let the operation continue through 
and it seems to be working properly, but without being able to put 
breakpoints before and after the Paste() code I really have no way of 
debugging my code because I perform special operations specific to the kind 
of shape being copied. 

Is there an event or something that needs to be processed in order for the 
paste operation to succeed?

Thanks.

I did try doing System.Windows.Forms.Application.DoEvents() and then placing 
a breakpoint after that. So my code goes like this: 

Paste()
DoEvents()
--Breakpoint--

What I saw was the copied shape drop onto the page and then my appliction 
hung up. It appears the application only hangs if I have a breakpoint 
somewhere after I do the paste. I am not sure what is going on though and why 
a breakpoint would cause the application to hang. 

Thanks.

might not be the application, might be a system event since the visio is 
unaware of break points.

Something is going on. When the application hangs I right click it and tell 
it to close and then I get a form for closing it and asking to restart it 
when I close it. Then The current execution goes back to Visual Studio but I 
am unable to change anything because VS is still waiting. Eventually I can 
click the stop button at top of VS. I then have to wait for VS to prompt me 
to stop debugging.

I installed the C# Express 2008 and it seemed to fix my problem. It appears 
MS has a problem with threads in VS 2005. It is a known issue which 2008 
addresses.
