I posted info on my MsgBox Blaster v0.80 earlier this week in Tips N Tricks, this may be a more appropriate forum.
viewtopic.php?t=6850
A new version of MsgBox Blaster is available, which includes changes suggested by eps, Num3 and GPI.
a) Cancel/TryAgain/Continue is enabled only for Win2000 and WinXP
b) MessageBoxH procedure has been corrected and Custom Location has been added, allowing you to set the xy coordinates.
c) Removed constants that were already declared in PureBasic and made other minor refinements to the constants/procedures.
I'll be on vacation in Las Vegas this week

a) Copying constants/procedures specific to the current message.
b) Just realized that I forgot to add the code to set "Help" as the default button.
c) Include Select Case Statements after the messagerequester code.
d) Integrate MsgBox Blaster with jaPBe (incredible work GPI!)
e) Add the ability to spit out VB6 msgbox code.
Here's the download link.

This is still far from a polished piece of work, there are a lot of rough edges. All feedback is welcome!
