Problem editing/saving Word doc to SQLServer

I'm currently using visual studio.net and sql server, programming in
vb.net and asp.net.

i'll upload a word document, it will be saved in a directory, then the program will go into the directory to find the file uploaded and run a macro in it whereby it will insert a number(ID) i retrieve from my database into the word document. Then after which i will update the directory and save the final file into the database.

But this is where i encountered a problem. The file i saved in the
database is the file in which i had uploaded without the ID inserted. Is
there a way whereby i can save the word document with the Number inserted
into my Database? How do i capture the file in which the Number has already
been added into?
