We have written an application in VBA in a Word Template. This application has been written over a number of months and various bits added etc. At one point the application became unstable. Word would crash unexpectedly. We then went through the application and made sure that there was no redundant procedures left in the project. We also reduced the size of several arrays. After this the project was again stable. More features were then added to the project and once again it became unstable. We again redimensioned arrays to smaller sizes and all was well again. This suggests to us that VBA may be running out of memoery.

The project is complex and uses many forms, some of which have command buttons with graphics rather than text. We have used .GIF files for the graphics. The template, when saved, is about 2800Kb.

Is it a memory/resource problem. If so does any one know how to fix the probem? Are there limits on the size of an application?

I would guess that it is a threshold problem. Some categories have a maximum size. For instance, an integer in VB can only be 32,767 to -32,768. You don't run out of memory if you exceed that, you exceed the gizmos limitations.

Now, integers are automatically checked for exceeding that, but you might be encountering some more subtle area that nonetheless has a threshhold.

The next thing I would try would be putting parts of the functionality that you need and put it into different templates, so that the whole app is not in just one template.

Also, be sure to limit your use of global items.
