vb.net窗口遍历 vbnet遍历控件

IT技术遍历

vb.net 遍历正在运行的虽有窗口和句柄For Each i As System.Diagnostics.Process In System.Diagnostics.Process.GetProcesses
Next
vb.net 历遍项目的窗体Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myAssembly As System.Reflection.Assembly = System.Reflection.Assembly.GetExecutingAssembly()
Dim TheTypes As Type() = myAssembly.GetTypes()
Dim myType As Type
For Each myType In TheTypes
If myType.BaseType.ToString = "System.Windows.Forms.Form" Then
ListBox1.Items.Add(myType.Name)
End If
Next
End Sub
VB.NET 遍历 DataGridView遍历vb.net窗口遍历的例子vb.net窗口遍历：
Dim i, j As Integer
For i = 0 To DataGridView1.RowCount - 1
For j = 0 To DataGridView1.ColumnCount - 1
MsgBox(DataGridView1.Item(j, i).Value)
Next
Next
注意：与Excel的单元格命名规则不一样vb.net窗口遍历 ， 这里的 Item(j, i) 中vb.net窗口遍历，列号 j 在前vb.net窗口遍历，行号 i 在后 。
vb.net panel里的控件如何遍历Public Sub ReSetText(Control ctrl)
Dim ct As Control
For Each ct In ctrl.Controls
Try
For Each ct2 As Control In ct.Controls
ReSetText(ct2)
Next
Catch
End Try
If (TypeOf ct Is TextBox) Then
ct.Text = ""
ElseIf (TypeOf ct Is ComboBox) Then
Dim cb As System.Windows.Forms.ComboBox = DirectCast(ct, System.Windows.Forms.ComboBox)
cb.SelectedIndex = -1
End If
Next
End Sub
因为textbox在窗体里的panel里，你只遍历窗体的控件是不够的 。
vb.net中如何遍历程序窗体中的控件？并读写控件的数据 。Public Sub GetAllControls(ByVal InContainer As Control, ByRef RecieveList As ListBox)
For i As Integer = 0 To InContainer.Controls.Count - 1
If InContainer.Controls.Item(i).Text"" Then
GetList.Items.Add(InContainer.Controls.Item(i).TextvbCrLf)
End If
If InContainer.Controls.Item(i).Controls.Count0 Then
GetAllControls(InContainer.Controls.Item(i), GetList)
End If
Next
End Sub
这段代码可行，但不能遍历菜单和工具栏，要按需要修改
关于遍历VB.net窗体里面控件的问题可以的，需要判断控件类型并做一下类型转换 。
For Each c As Control In Me.Controls
If TypeOf(c) Is TextBox Then
Dim t As TextBox = CType(c ,TextBox)
'调用t的方法即可
End If
Next
