Redirect in WebQueryOpen

It looks like very simple task - redirect to another element in WebQueryOpen , but when I tried to do it it did not work ! I mean in WQO JavaScript does not work well (or probably at all).
So I found good solution for me, and I would like to share it:

We have to take current document and then change the value in $$HTMLHeader.

How we can change language in database?

Actually I have one task right now. The main goal of this task is to find the best approach for changing current language in database. Let's say we have lotus notes database on English language and we have to change it to Spanish / German / any other .

So, what I think, is to export this database in DXL, then we cut/took all English wording, translate them to new language, then we have to modify this DXL file and them import it back as database. It is only 1 approach, and I would be happy if anybody can propose any other.

It is really interesting for me, and I guess for other people.

software for testing application based on Lotus Notes

This question is quite important for me right now. Does anybody know about any approaches for testing application in Lotus Notes client?

Actually I tried to use couple of these kind software but I did not like any of them.

So my main question to Lotus community. Who has experience in this question and can advise?

Thanks!
