Help/About button

[ReverendJ1]

I was wondering if there was any way when using forms with the $WS_EX_CONTEXTHELP extended style if you could make the '?' button bring up another gui (i.e. an about/help box), instead of showing tooltips.

Thank You

VERY nice gafrost !! You are really good in using GUIRegisterMsg

and it's very powerfull function.

Thanks gafrost! Took me a while to figure out what I had to do with your code (first I just copied and pasted into a blank script), I kept getting this error:

C:\Deleteme\test.au3(80,26) : WARNING: $GUI_RUNDEFMSG: possibly used before declaration.

Return $GUI_RUNDEFMSG

~~~~~~~~~~~~~~~~~~~~~~~~~^

C:\Deleteme\test.au3(80,26) : ERROR: $GUI_RUNDEFMSG: undeclared global variable.

Return $GUI_RUNDEFMSG

~~~~~~~~~~~~~~~~~~~~~~~~~^

C:\Deleteme\test.au3(27,53) : ERROR: GUIRegisterMsg(): undefined function.

GUIRegisterMsg($WM_SYSCOMMAND,"WM_SYSCOMMAND_Events")

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^

C:\Deleteme\test.au3 - 2 error(s), 1 warning(s)

I kept trying to fix it and it wouldn't work. But then I just recopied it in it's entirety clicked continue anyway when the error came up and it worked!

Thanks a ton!

Most of them a pretty simple actually, just a matter of finding the correct message you need to work with.

The above I posted in scripts and scraps last week (less a few lines) and another one as scrap
