Public Class Form1
Public Class SquareClass '把多线程调用的函数封装到类中,通过类事件返回
Public Value As Double
Public Square As Double
Public Event ThreadComplete(ByVal Square As Double)
Public Sub CalcSquare()
Square = Value * Value
RaiseEvent ThreadComplete(Square)
End Sub
End Class
Dim WithEvents oSquare As SquareClass
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click '多线程返回值测试,当线程运行完成激发事件
oSquare = New SquareClass()
Dim t As New Threading.Thread(AddressOf oSquare.CalcSquare)
oSquare.Value = 30
t.Start()
End Sub
Sub SquareEventHandler(ByVal Square As Double) Handles oSquare.ThreadComplete '响应事件函数
MsgBox("The square is " & Square)
End Sub
End Class
