All the menu/form text is hardcoded into Hydra, your best bet for a translation is to make me a text file showing the english words, where they are in the program, and their german replacement. Then I can figure out how best to implement them from there.
Could you use arrays for all the texts you need. The way one could easily exchange the texts without having to go through your sourcecode.
The texts will still be hardcoded then:
Menu[7].item1="A&bout Hydra IDE"
Helptxt[0].tooltip="This is a tooltip text"
Or make an ini-file system that stores all names.
So one can change the texts displayed during runtime.
When you do so right from the start it isn't that much more work. But changing your code later by hand is PAIN (tm).
