vb.net中listbox内容自动换行如何实现

也不是不可以实现，只不过复杂一点而已，具体看下面代码。不过在需要换行等情况下的文本显示，还是建议用RichTextBox开启只读属性比较省心、比较合适。

Private Sub AutoNextRow()

'获取ListBox行集合文本

Dim length As Integer = (ListBox1.Items.Count - 1)

Dim items(length) As String '行文本数组

For i As Integer = 0 To length

items(i) = ListBox1.Items(i).ToString

'处理ListBox换行

ListBox1.Items.Clear() '清空行内容

Using g As Graphics = Graphics.FromHwnd(ListBox1.Handle)

Dim result As New List(Of Object)

Dim w As Single = ListBox1.ClientSize.Width

Dim sf As SizeF, str As StringBuilder

For Each s As String In items

str = New StringBuilder

For i As Integer = 0 To (s.Length - 1)

sf = g.MeasureString(str.ToString s(i), ListBox1.Font)

If sf.Width w Then

result.Add(str.ToString)

str = New StringBuilder

End If

str.Append(s(i))

If i = s.Length - 1 Then result.Add(str.ToString)

ListBox1.Items.AddRange(result.ToArray) '填充行内容

End Using

End Sub

VS2010用VB语言实现数据库连接，并将表中的数据显示在GridView上。

'================================ACCESS=================================

Public AccessConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _

"Data Source=D:\Simple.mdb;" _

"Persist Security Info=False"

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Try

Dim AccessString As String = "SELECT * FROM 示例表 "

Dim AccessConn As New OleDb.OleDbConnection(AccessConnectionString)

AccessConn.Open()

Dim AccessAdapter As OleDbDataAdapter = New OleDbDataAdapter(AccessString, AccessConn)

'有返回值

Dim TempDataSet As New DataSet

AccessAdapter.Fill(TempDataSet)

DataGridView1.DataSource = TempDataSet.Tables(0)

AccessConn.Close()

Catch AccessException As Exception

MsgBox(AccessException.Message)

End Try

End Sub
