Software dll update checker?

[Xillez]

Hey, I'm making a text editor for my own programming language and I wanna make a simple software updater for it. I've been searching online for tutorials and how to's, but couldn't find any that explained what I was after/covered the code I needed...

Can you guys help me with this one?

One easy way to do this is to keep the version number in a registry key. All your updater has to do is read the key to see if the update has been applied.

I assume you are using Windows because only Windows uses dlls.

You might also keep the version number in a configuration file that also holds the other settings for your editor.

Avoid hard-coding the version number in the code.

ok, thanks for the info but how can I like send the updater the data it needs? or does it find it on it's own?

The updater finds the data on its own because it knows where to look. I mean you coded both programs.

If you use a settings file you can do things like:

version= 2.5
 

Then have the updater read the file looking for "version=" to find the data.

To update the file you would make a copy substituting the new version for the old one. Then copy back on top of the original. Then delete the copy.
