Use the code for anything, just submit suggestions and bug fixes to above address. 
 
4/13/2004 - 1.0 Initial release 
 
4/20/2004 - 1.02 Bug fixes and some enhancements 
 
Fixed bug where the edit would only accept hex digits. Also now allow negative sign "-" to be entered  
Added NES_METER style to make the small bar under the edit field optional  
Control will now reconfigure itself when changing style bits  
Fixed max value bug. The full range is now accesible with the popup  
Added NES_LIVEUPDATE style. This style allows the control to notify it's parent during value tracking. Without this style, the parent is updated only at the end of tracking  
Demo has been updated to show the new features  
Added DDX_NumericEdit() function for DDX support  
Now using the active window caption color for the bar colors  
Changed hardcoded custom messages to use windows registered messages so as not to cause any conflict with other custom messages
