关于VB点虐 Combobox联动问题

删除所有消皮列表项目

combobox2.Clear

增加新项目拿滑差,n为你选中第一个Combobox索引，来确定你让缺二维数组的值

n = Combobox1.Items.SelectIndex

GetLength(1) 是得到你二维数组的长度

for i = 0 to aTemp.GetLength(1)

if aTemp(n,i) "" then

Combobox2.Items.Insert aTemp(n,i)

end if

next

vb点虐 中两个RichTextbox的滚动条如何联动？

Public Class Form1

Public Declare Function GetScrollPos Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal nBar As Integer) As Integer

Public Declare Function SetScrollPos Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal nBar As Integer, _

ByVal nPos As Integer, ByVal bRedraw As Boolean) As Integer

Private Sub RichTextBox1_HScroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox1.HScroll

Dim lngPos As Long

lngPos = GetScrollPos(Me.RichTextBox1.Handle, 0)

SetScrollPos(Me.RichTextBox2.Handle, 0, lngPos, True)

End Sub

Private Sub RichTextBox1_VScroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox1.VScroll

Dim lngPos As Long

lngPos = GetScrollPos(Me.RichTextBox1.Handle, 1)

SetScrollPos(Me.RichTextBox2.Handle, 1, lngPos, True)

End Sub

Private Sub RichTextBox2_HScroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox2.HScroll

Dim lngPos As Long

lngPos = GetScrollPos(Me.RichTextBox2.Handle, 0)

SetScrollPos(Me.RichTextBox1.Handle, 0, lngPos, True)

End Sub

Private Sub RichTextBox2_VScroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox2.VScroll

Dim lngPos As Long

lngPos = GetScrollPos(Me.RichTextBox2.Handle, 1)

SetScrollPos(Me.RichTextBox1.Handle, 1, lngPos, True)

End Sub

End Class

vb点虐 如何实现窗体中多个文本框控件与同一窗体中datagridview控件联动？

文本团纤高框也可以绑定的竖启，C#为例：

this.textBox.DataBindings.Add("Text", this.Food, "塌尺Name", false,

DataSourceUpdateMode.OnPropertyChanged);
