VB.NET中怎么实现每单击一次按钮,文本框就多出现...

Dim n As Integer, b As Integer, a(13) As Integer Private Sub Command1_Click() If b < 5 Then b = b + 1 x = Int(n * Rnd()) + 1 Text1.Text = Text1.Text & a(x) & " " a(x) = a(n) n = n - 1 Else Call Form_Load End If End Sub Private ...

可以的呀??? Public Class Form1 Public a As Short = 1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click a = a + 1 Label1.Text = a End Sub End Class

Dim i As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click i = i + 1 If i = 1 Then MsgBox("我是代码一") ElseIf i = 2 Then MsgBox("我是代码二" & Now) Else MsgBox...

Dim i As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click i = i + 1 If i = 1 Then TextBox1.Font = New System.Drawing.Font(TextBox1.Font, FontStyle.Bold) Else Te...

用Create talbe 'TableName' 字段名,类型,长度,.........用SQL语句就行了呀,我做过,肯定行的,要使表名不同就在后面加个序号,

这个定义放在查询按外面做全局 在那个下拉里面添加一样的就可以实现

按钮控件无法实现像您说的那样 可以用Check控件来代替 将其Style属性设置为1-Graphical 外形就和按钮一样了 按钮控件和Check控件都有picture这个属性 通过它可以在上面加图片

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a = New System.Random() Textbox1.text=a.next(10)+a.next(10)+a.next(10)+a.next(10)+a.next(10)+a.next(10)+a.next(10)+...

应因为这个按钮你之前双击过一次,而后你做了某些操作导致这个按钮的click方法失效,因此,你再一次点击按钮,就会出现新的点击事件方法。

定义一个全局的静态变量,例如 Dim Shared c As Integer 在 button 的 click 时间里写入 c = c + 1 这个 c 就是 点击次数了
