Unhandled exception occured

[Shan]

Hi,
I am creating a data model diagram with Reverse
Engineering. Actually i have two Data Model Diagram files
(a.vsd,b.vsd) for different modules. Actually I want to
integrate these two DMD into one. So i just copied this
diagrams(with X Position and Y Position Protected) and
Pasted it in a new Data Model Diagram file(c.vsd). This
combined file has a size of 1500kb. Now I removed the
protection(X position, Y Position) and i could change the
allignments. I could also able to double click the tables
and find their properties and if needed i could able to
change the relationships. But once i save this file and
try to open this file again i am not able to open the
table's properties and the file gets corrupted and it is
no longer usable. While closing the file i get an
Exception message "An Unhandled Exception Occured".

I am using Visio 2000 SR1(6.1.1023). I have increased my
virtual memory also and Still i keep getting this error.
Can any one help me out from this problem. Is there any
other way to integrate these two different files(Reverse
Engineered) into one file.

Thanks for the Help.
Regards,
Shan

Shan,
When you want to divide a model into sub-models, you should probably
consider using ER Source Models. Search Visio's help for "About ER source
models (Database model)" for more help on this. (Note this is a feature of
the Enterprise edition of Visio, not included in Pro. if you are using
Pro, let me know and perhaps there is a different avenue we can take.)

Basically, using ER Source models will allow you to reverse engineer Model1
into ER Source Model A, Model2 into ER Source Module B, and so on... To
combine one or more ER Source Models, create a new Database Model Diagram
and add the ER Source Models to its project (Diagram | Project | Add
Existing Document...), then build the project (Diagram | Project |
Build...), this will combine the models of each ER Source Model into this
document's model. Now you can drag the tables (and views) from the Tables
Window (Database | View | Tables) to the diagram if you wish. From this
Database Model Diagram which combines all of you sub models, you can
generate DDL (Database | Generate) etc. If you edit the model (for example
change the name of a table's column) in this diagram you will have an
oppertunity to migrate the changes back to your ER Source Model(s).
