MessageBoxTimeout

There is apparently an undocumented WinAPI MessageBoxTimeout in user32.dll that would be very useful to me, but my attempts to write an interface to it have failed. I am using CVF6.6B. Can anyone help, please?

Search for MessageBoxTimeout on Google and you will know as much as I do. It has the same arguments as MessageBoxEx plus an extra dwMilliseconds argument for the time to end.

It would also appear that it isn't defined in the user32 export library so you have to dynamically activate user32.dll to get to it.

The attached seems to work. Just USE the module and call the routine. The only thing you can't do is pass NULL as the caption. You should pass 0_WORD as the LanguageID argument.

Tested with Intel Visual Fortran but should work with CVF as well.

Steve,
Many Thanks - it worked first time for me, so now I can add it to my collection of unobvious useful routines.
