Hi All, sorry it has been a long time since i have helped or posted here, i got a new job using a really old language called unidata ;-)

My Question is this :
I have a DLL i created in VB.NET, that opens word and does a series of find and Replace, after the find and replace i have to save the changes not to the harddrive but to a property of the DLL, i was thinking that i could use memory stream, but i can't get this to work, I get an
error as follows :

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in word_find_replace.dll

Additional information: Type mismatch.

Here is the code :

Dim ms As New System.IO.MemoryStream
...
' code that does the find and replace
...
oDoc.Save(ms)

Thanks!
