Update the application part by part

Hello
I developed a VB6 program and its very big and I cannot send complete updates via internet every time.

I see big programs update partly.
Can I make some changes to my project and make it update via internet part by part as needed?

What is the main Idea to do it?
Where is the start point?
Is it posible and easy to change a project to be like that ?

Thanks

One solution could be splitting your program in logical parts and create the EXE for the forms and put as much of other code in logical blocks in separate DLLs.

Other solution, keep it as it is and create a patch file instead of distributing the complete EXE.

Hello

Can I use it with Inno setup made instalation files?

Thanks

You want to use INNO to create an installer for the patches??

Hello

I'm using INNO setup as installer program for my project.
After making Install file that works good but is a little big I need to send new update of the application to users.

I wish to use patch maker to make small update files that can send via internet and just fix certain parts of big application or add additional small parts to the instaled big application.

Did I explaine it clearly?

Thanks

You don't need INNO setup to distribute the patch.

If you tried the patchmaker tool then you would have noticed then it can eiter:
- Ask to user to locate the directory
- Use an already specified location
- Use a value of registry key to the location of the directory which contains the "non patched" files
