• Visual Studio 2008 (Pre-release) SetValue on Field, or Just Use Property?

  Using BezierSegment as an example, can someone explain the difference using SetValue with the BezierSegment.Point1Property field and directly setting the BezierSegment instance's Point1 property There should be no difference. CLR properties like Point1 are there to simplify the coding experience and also provide "up-front", discoverable strong typing since DependencyProperty SetValue has to take objec ...Show All

• Visual Basic Overflow???

  This code is generating an overflow exception and I really don't think it should be: Dim u64HiBit As UInt64 u64HiBit += &H8000000000000000 or u64HiBit =   u64HiBit or  &H8000000000000000 In my understanding this is simply setting the hi-bit in an unsigned integer. It certainly shouldn't cause an overflow unless it's not really a 64-bit entity. There is a worse possibility which is that it truly isn't supported w ...Show All
