Guys

Is there a way in C# to create a word object directly from a memory
stream without passing that to hard disk (file stream). I think it
doesn't makes sense to create a file just to read it again in to word
object. If some one has some brilliant idea please share.

In a nutshell this is what I'm currently doing
ByteArray --> File Stream --> Word Object
and this I want to do
ByteArray --> Memory Stream --> Word Object


thanks

There is a way. I've seen this in C++ code on somebody's blog a while
ago--it was too speed up the app for performance, as the bytearray was
streaming in from a port connected to the internet. I just don't have
a solution offhand right now. One way, however, that might work for
you is in the C#3.0 Cookbook (O'Reilly). Keywords: redirection,
RedirectStandardOutput property of the Process.StartInfo class, also
look to recipe 12.20, writing to multiple output files at one time.

Hope this helps...

I did something similar to this. I created an xml document, not word
document, using the StringReader class. It creates a memory stream
from a string, and I was able to substitute it into anywhere a file
stream was required.
Hope this helps.

I dont think it will work because I'm currently using .net 1.1 and
they way the word object can be created is creating a word document
from a file stream and then using that word doc. Now the problem is I
dont want to create a word document physically on the hard disk. I
want to create the word object directly from bytearray as the word
document is stored as blob in database.

Also its a different case from creating XML as in .net there is
inbuilt support for XML but not for word.

I hope I'm clear this time. In anycase thanks for your help.

cheers

Try upgrading to 3.0--the express version is free. Then try it and
see if it solves your problem.

I guess you are right. I was just checking if there are other ways to
achieve this...
In any case thanks a lot your help.
