Is the number of controls in a .vsd limited?

[Jumpy]

Hello,

this is a CrossPost to a german visio forum, where a user asked, wheter the number of controls (comboboxes, radio buttons, checkboxes, ...) allowed inside a drawing is limited, because after adding a control to a drawing that has arround 70 control already, he gets an error message like:

Error(1441): Visio can't add a new control, because the file contains to many shapes, pages or master-shapes.

Has someone already expirienced sth. like that?

Here the link to the german forum:

Thanks,

Edit: Visio 2010.

I couldn't find anything on this, but I remember a limit being mentioned. Each control is somehow a window in a low-level sense and eats up a lot of resources (at least for the Visio 3.0 or 4.0 time it did). So I'm pretty sure there was a limit at some time, and it may still be there, but I can't site any proof or any numbers as to what that limit is.

I just tested in Visio 2010 and was able to add 700 Buttons to the page, no problem (ok, slow, but worked!) No code-behind, but I was able to click the buttons.

I added 800 buttons to a page in Visio 2007 (on a Virtual PC), and Visio had problems rendering the last 60 or so. You could drag-select them, but not see them!

Visio 2010 64-bit was able to handle and display 1000  buttons, although it takes around 10 seconds just to toggle between run-mode and design-mode.
