I have files called “1.c , 2.c, 3.c and 4.c�.

With these four files I created a project in visual studio 6.0.
This project creates “Raja.dll� (and this “Raja.dll� file will be used in another project).

Here is my question…

As you know after we get *.dll file, if we want to change few lines in any of the above files (say 1.c) we have to go back to project and change the required lines (in 1.c file) and then create new *.dll file and so on..,

Instead of this is there any way to create updated *.dll (say new_Raja.dll) from Raja.dll and 1.obj files (“1.obj� file get it from “1.c“) directly instead of going back to the project and change 1.c and create “Raja.dll�?

The reason for asking this is I donot want to give access to “2.c, 3.c, 4.c�.

Can we do this in visual studio?
Is there any way to do this in Matlab also?

Let me know if you donot understand my question.

Thank you for your time,

Raja
