Patches

[cyprus106]

I was just wondering... How would you install a patch to your EXE. I've recently distributed a program, and then i got sever notifications of a bug, and so I created a fix, but now I need to send it out in the form of a patch, how would I go about doing this? The thought never really crossed my mind. Cyprus

Are you thinking of making a tool for this purpose yourself or getting something from the internet ?

I tried this in a dos box:

C:\>copy con test1.exe
1
2
3
^Z
1 file(s) copied.
C:\>copy con test2.exe
3
2
1
^Z
1 file(s) copied.
C:\>fc /b test1.exe test2.exe
Comparing files test1.exe and TEST2.EXE
00000000: 31 33
00000006: 33 31
C:\>


It can't be to difficult to create a program to generate a c-source from the differences between the two exe-files.
If you want to start programming, have a look this code:

One thing: what if the patch is bigger than the program

life can be so easy

PatchWise Free 3.15 Beta (freeware)

This is an easy way for authors to create patches for their software. It creates small, self-extracting files that are easily distributable. Everything is handled through a wizard-like interface.
