vb.net遍历进程 vb遍历文件夹的所有文件

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).Text  vbCrLf)

End If

If InContainer.Controls.Item(i).Controls.Count  0 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

VB关进程

'你要关闭什么进程

'就写

'Call taskkill("进程名.exe")

'注意大小写啊

这是我回答的 复制自己回答的内容不算复制吧?????

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
