Code updated for 5.20+

This is a simple replacement for the MS ShellAbout_() about box which, if you use it, effectively hands your copyrights over to Microsoft.

Tweak the icon libraries listed in about() and text to suit your own preferences. Hope it can be of any use, just wrote this for myself

I get an error for line 42 when running this ("LoadFont can't be called inside a
StartDrawing/StopDrawing block") -- so why does it work for you and not I?

Try without the debugger

Posted: **Thu Jan 04, 2007 1:01 pm**

Probably because you run with the debugger enabled. This error message seems to be by design to avoid a
particular problem with chrashes.

I've changed the code, but I'm at work ATM, so I haven't been able to test it. Hope it works now?

Posted: **Thu Jan 04, 2007 1:12 pm**

Works for me with debugger on.

Posted: **Thu Jan 04, 2007 3:48 pm**

nice!

Posted: **Thu Jan 04, 2007 4:27 pm**

Works fine here, nice one.

> Try without the debugger

Okay, it works without the debugger, but that means it's a bug then, because
we shouldn't have to disable the debugger to get code working. If the debugger
rejects it, then it's doing it for a reason, leading to the conclusion that bypassing
the debugger is producing risky/unsafe code.

> Works for me with debugger on

Well, then there's a serious issue with PureBasic somewhere. I'm seeing too
many posts lately where one person's experience with a snippet is producing
different results to another person's.

@Fred/Freak: Maybe there could be an option to launch PureBasic in some
sort of "Safe Mode", which disables any third-party extensions etc? Might
be useful to sort out any issues from one machine to another.

Posted: **Thu Jan 04, 2007 10:34 pm**

Thanks for testing! @PB, the problem you ran into is discussed and answered by Fred here:
http://www.purebasic.fr/english/viewtop ... 80&start=0

He says it's fixed, but I'm not shure what he means by that. I didn't see anything on this
in the help either (might have missed it), so..

Anyways, I moved the loadFonts() outside the startDraw()/stopDraw() pairs, and it seems to
work as advertised now.

Here's another one if you need more possibilities. You can either specify a path to an about.html
or else it will display an editorgadget with 'hardwired' text in it.

I like the possibilities html gives me though:
