Detecting W3 version?

[klemen]

Hi

Somehow I need to detect the current W3 version from an external program because I would like to make some kind of "version switcher" but it would autopatch to 1.26a if it detected a lesser version.

Does anyone have a clue how would I detect the current version of a W3 install? Blizzard must have this information stored somewhere in order to trigger an autoupdate over bnet, unless it is hardcoded into the binary. In that case I am guessing the best way to do is to take a hash of the war3.exe and other binaries and compare them to 1.26a hash.

I'm not sure I understand your question, but you can see your version number at the bottom right of the main menu.

Patch.txt has all the updates, but I bet you would need File I/O to read it...
(It is in the main warcraft 3 directory for me)
I also looked in the registry and didn't see anything. This is the only way I found...

It's probably hard coded in the binary. I guess I'll just do a hash over the executables and compare them with a known 1.26a hash.

Just wondering, why wouldn't reading from Patch.txt work for this?

The version is actually written in the file information of war3.exe (Properties->Details) so that's where I'll read it.

@patch.txt: If you install W3 from scratch there is no Patch.txt afaik.

Patch.txt might also be localized.

Do remember that the patcher program can fail if any file has been modified (fails a checksum test). You will need to detect that case and then abort your program.
