(About the author)
 
     This code is a VB implementation of the high precision multimedia timer which can be found in the winmm.dll. ---- I wrote this code because of the same reason I created my multiple undo implementation: I wanted to have a smart solution that can be easily added to different VB projects, that doesn't clutter the code, that doesn't let depend my project on another custom OCX or DLL file and that is object oriented as much as possible. ---- The demo project's intension is NOT to show that the multimedia timer is or is not more accurate than the standard VB timer. It's primary task is just to show how to use the timer class and how to instantiate and handle more than one timer object. ---- For more information have a look at the readme.txt please. -- NEW: I added a high precision profiler class. -- NEW: UserControl instead of class file. Doesn't crash anymore when run compiled. Much easier handling.

There is also a good freeware multimedia timer that can be downloaded at:

http://www.mvps.org/ccrp/

although you do not get the source code for it. The CCRP timer also has a count down feature which is nice.

Anyhow, nice work on this one.

Thanks Sebastian,

I needed the high resolution qualities of timesetevent but could not get my version to not crash in EXE format. Your implementation of this much underrated, and very necessary, function was first rate.
