如何判断点击哪个按钮？
想写个过程A用来判断点击了哪个按钮，button1和button2按钮都调用这个过程，如果点了button1按钮执行过程A中的一段代码，如果点了button2过程就执行过程A中的另一段代码，请问如何在过程中判断点击了哪个button控件？ --------------------编程问答-------------------- 用 Select Case --------------------编程问答--------------------大哥这个谁都知道，不是重点！！！！！！！！！！！！ --------------------编程问答-------------------- try...
Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click, Button1.Click--------------------编程问答--------------------
If DirectCast(sender, Button).Name.ToLower = "button1" Then
MessageBox.Show("点了button1")
Else
MessageBox.Show("点了button2")
End If
End Sub
妙招，我也常用这方法，呵呵 --------------------编程问答-------------------- 也可以通过一个变量记录点击的是哪个按钮 --------------------编程问答-------------------- VB.NET code:
Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click, Button1.Click
Dim bttn As Button
bttn=sender
If bttn.name="button1" Then
MessageBox.Show("点了button1")
Else
MessageBox.Show("点了button2")
End If
End Sub --------------------编程问答-------------------- 楼上说的方法挺好
也可以获得控件的索引号来判断 --------------------编程问答--------------------
Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click, Button1.Click--------------------编程问答-------------------- 楼上都回答了，sender.name即可搞定 --------------------编程问答-------------------- 之前还没用过。。呵呵 。。学习了 --------------------编程问答--------------------
Call A(DirectCast(sender, Button).Name.ToLower())
End Sub
Sub A(ByVal strFlag As String)
Select Case strFlag
Case "button1"
MessageBox.Show("点了button1")
Case "button2"
MessageBox.Show("点了button2")
End Select
End Sub
This Answer is Good for you. --------------------编程问答-------------------- Private Sub Button_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click, Button2.Click
Dim btn As Button = CType(sender, Button)
If btn.Name = "Button1" Then
MsgBox("Button1")
ElseIf btn.Name = "Button2" Then
MsgBox("Button2")
End If
End Sub --------------------编程问答-------------------- 晚太多了，嘿嘿.......用Button.CommandName判断啊 --------------------编程问答-------------------- 又学习到一个自己不知道的问题了~~ --------------------编程问答-------------------- 0
--------------------编程问答-------------------- 就用sender判断就行了 --------------------编程问答-------------------- 定义公共变量来判断单击了那个按钮 --------------------编程问答-------------------- 窗体上每个控件都有个 Tab index。 --------------------编程问答-------------------- --------------------编程问答--------------------
可以试试，
--------------------编程问答-------------------- Private Sub MoveToStart()
Dim startingPoint = Panel1.Location
startingPoint.Offset(10, 10)
Cursor.Position = PointToScreen(startingPoint)
End Sub --------------------编程问答-------------------- 用sender.name获取点击按钮的名称 --------------------编程问答-------------------- 学习了，果然好用 --------------------编程问答-------------------- --------------------编程问答-------------------- 学习了，高手多多啊！ --------------------编程问答--------------------
三楼的我也常用。 --------------------编程问答-------------------- Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click, Button1.Click
msgbox(sender.text.tostring)
End Sub --------------------编程问答-------------------- 还没有用过学习了
--------------------编程问答-------------------- 每个控件是否有个tag属性，可以用这个属性进行编程 --------------------编程问答-------------------- Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click, Button3.Click, Button4.Click, Button5.Click
Select Case sender.text.ToString
Case "Button1"
Case "Button2"
Case "Button3"
Case "Button4"
Case "Button5"
End Select
End Sub
End Class
