Q1: VB.net 如何绑定许多button和数组

vb.net里没有像vb那样的控件数组。也就是说复制控件后粘贴没有提示vb.net控件绑定你是否创建控件数组。

vb.net控件绑定你可以试验下面的代码。

Form1.Designer.vb 设计器中的窗体代码如下vb.net控件绑定，上面有六个button。最右边的用来改变前5个地text：

Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated() Partial Class Form1

#Region "Windows フォームデザイナによって生成されたコード "

System.Diagnostics.DebuggerNonUserCode() Public Sub New()

MyBase.New()

'この呼び出しは、Windows フォームデザイナで必要です。

InitializeComponent()

End Sub

'Form は、コンポーネント一覧に后処理を実行するために dispose をオーバーライドします。

System.Diagnostics.DebuggerNonUserCode() Protected Overloads Overrides Sub Dispose(ByVal Disposing As Boolean)

If Disposing Then

If Not components Is Nothing Then

components.Dispose()

End If

MyBase.Dispose(Disposing)

End Sub

'Windows フォームデザイナで必要です。

Private components As System.ComponentModel.IContainer

Public ToolTip1 As System.Windows.Forms.ToolTip

Public WithEvents Command2 As System.Windows.Forms.Button

Public WithEvents _Command1_4 As System.Windows.Forms.Button

Public WithEvents _Command1_3 As System.Windows.Forms.Button

Public WithEvents _Command1_2 As System.Windows.Forms.Button

Public WithEvents _Command1_1 As System.Windows.Forms.Button

Public WithEvents _Command1_0 As System.Windows.Forms.Button

Public WithEvents Command1 As Microsoft.VisualBasic.Compatibility.VB6.ButtonArray

Q2: 用.net做网页！用VB语言怎么把label控件绑定到一个数据库的列！

可以使用Datalist,

Repeater

等控件.

绑定数据源后,在ItemTemplate添加label,

设定labelvb.net控件绑定的Text为某列vb.net控件绑定的值.

不懂可以加vb.net控件绑定我QQ问.注明"dotnet"

Q3: vb.net的DataGridView数据绑定

在配置文件app.config中加入

appSettings

add key="LotDBConnection" value="DATA SOURCE=数据库连接;PASSWORD=密码;PERSIST SECURITY INFO=True;USER ID=登录名"/

/appSettings

//m_SqlPath 存放SQL语句vb.net控件绑定的XML文件

Dim sqlHelper As New SQLHelper("LotDBConnection")

Dim sqlRead As New ResourceHelper

Dim ht As New Hashtable

Dim strSQL As String

Try

'设置SQL文参数

ht.Clear()

ht.Add(ColumnName.USER_ID.ToString, Trim(Me.txtUserID.Text))

ht.Add(ColumnName.USER_NAME.ToString, Trim(Me.txtUserName.Text))

'数据查询

strSQL = sqlRead.GetSQLSentence("GetUserList", m_SqlPath, ht)

ds = sqlHelper.ExecuteDataSet(strSQL)

If ds.Tables(0).Rows.Count = 0 Then

MessageBox .Show ("数据不存在");

Else

'数据绑定

dgvUserMeisai.DataSource = ds.Tables(0)

End If

Catch ex As Exception

MessageBox .Show (ex.Message );

Finally

sqlHelper = Nothing

sqlRead = Nothing

ht = Nothing

End Try

Q4: vb.net动态添加控件，并且绑定了一些事件，这些事件只能对最新生成的控件做修改，之前生成的无法修改

比如说这样添加的计时器：

Dim Timer1 As New Timer

你要在合适的地方开始，比如窗体Load事件中，这样：

Timer1.Interval = 1000 '单位毫秒，1000毫秒＝1秒

Timer1.Enabled = True '启用计时器

然后在代码窗口上方下拉列表里选择Timer1的Tick事件，自动添加代码：

Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick

End Sub

这是计时器触发的事件，每秒触发一次，在这里面输入循环判断是否有日程即可。提示：你可以用Now对象获取当前的日期和时间。
