VB 2010 and Visual Basic 2012 has a feature that was originally added in the .NET 4.0 and that is available in the dot net 4.5 framework framework called: Environment.Is64BitOperatingSystem, which is a property that will return True if the operating system is 64Bit and False if the os is NOT 64 bit (x64) but is 32 Bit (x86). If using those versions and you only need to know the addressing for the operating system (OS), then go ahead and use Environment.Is64BitOperatingSystem. Also if the registry or another method in this example returns AMD64 or Intel64 then it IS 64-bit/x64 and not 32-bit/x86., 285 Downloads; Since: August 28, 2012)][

Thus, the highest resolution I was able to get was 15-16ms which is right around the GetTickCount timer resolution which is a part of the User32.dll library as well. While this project will not load in VB 2005, the codes will work with 05 since the timer was first added in version 2.0 of the .NET Framework. IF you want higher resolution Windows Timer Events, then try using the multi-media, but Un-Managed timer event called: timeSetEvent/timeKillEvent, which has a resolution of 1 ms., 26 Downloads; Since: August 28, 2012)][
