Private WithEvents TimerDrop As New System.Windows.Forms.Timer()
Public Event ShowcurrSquare(ByVal type As Integer, ByVal cell() As Point)
…………………………
InitcurrSquareLocation()
CalcurrSquareCoordinate()
*RaiseEvent ShowcurrSquare(currSquare.Type, currSquare.CellLocation)
AddHandler TimerDrop.Tick, AddressOf Drop
TimerDrop.Interval = 500
TimerDrop.Enabled = False
以上是我从class square中的初始化的一段,运行到打*处便出现object reference not set to an instance of an object的异常情况,可我仔细检查了好多遍了,对象我都用object实例化了,:(
