Hi Cathi,

I read the article - unfortunately the VB samples in the article do not work - there is a reference to ThisAppliation - which doesn't compile.

So, you're saying that setting Option Strict Off in VB.NET may do the trick?

Hope so - the other thing I'm going to to change is this...

wrdDoc = wrdApp.Documents.Open(strLargEnvTemplate)

To this ...

wrdDoc = wrdApp.Documents.Open(CType(strEnvelopeTemplate, Object))

... both compile and work on my dev box - and I saw a few examples that cast the file name into an object. Do you think this will make a difference?

>When you are working with different versions of Word or Excel, you will need to write your Word interfacing with VB.NET, using Option Strict Off or use Reflection in C# (or VB.NET). This allows for late binding so the compiler does not link to a specific version. Here is a MSDN article that explains this and provides examples:
