Hi

I am opening word from my vb.net app. Is there a way to call a procedure in
the vb.net app from a word macro?

Thanks

Regards
 
why are you posting this to the whole world?

anyway, I would suggest converting the code in the macro to something
useable in vb.net and placing it there thus eliminating the problem.

I can't help anymore without more details.
 
What I need is that when word does something, it informs the calling vb.net
app. Therefore I need word to be able to communicate with the vb.net app.

Thanks

Regards

It depends rather on what that something is and the circumstances in which
the VB.NET app is listening.
 
My example is given at the bottom. I need to call it from Word VBA. When I
build it I get two files one dll and other tlb. Can I just add these to
references in Word and start using or do I need to do something else before
that?

Thanks

That depends on whether the DLL implements a COM interface. If the DLL has a
COM interface, then you will be able to set a reference to it by going to
the Word VBA editor, selecting Tools, References, and then setting a
reference to your DLL.

Using Events would be the best method. You really don't want to have the client and automation
server calling each other:

See if the following helps:

Yes, I agree. This is what I started with but Word odes not expose
DocumentAfterSave and DocumentAfterPrint which are the two events which I am
after. Anyway my vb.net app can know when the document has been saved and/or
printed?

Thanks

Regards

If you intercept the "Before" events, then send the Save resp. PrintOut
commands in your code, the code will wait until the actions have been
processed, then proceed. You just have to make sure you set the Background
printing option to FALSE.
