我正在使用下面的更新来自另一个线程的控件(效果很好),如何调用Sub(名为UpdateList)?updateList使用所选SQL实例上的数据库列表更新ListView,不需要参数。
Private Sub CompleteEventHandler(ByVal sender As Object, ByVal e As Microsoft.SqlServer.Management.Common.ServerMessageEventArgs)
SetControlPropertyValue(Label8, "text", e.ToString)
UpdateList()
MessageBox.Show("Restore Complete")
End Sub
Delegate Sub SetControlValueCallback(ByVal oControl As Control, ByVal propName As String, ByVal propValue As Object)
Private Sub SetControlPropertyValue(ByVal oControl As Control, ByVal propName As String, ByVal propValue As Object)
If (oControl.InvokeRequired) Then
Dim d As New SetControlValueCallback(AddressOf SetControlPropertyValue)
oControl.Invoke(d, New Object() {oControl, propName, propValue})
Else
Dim t As Type = oControl.[GetType]()
Dim props As PropertyInfo() = t.GetProperties()
For Each p As PropertyInfo In props
If p.Name.ToUpper() = propName.ToUpper() Then
p.SetValue(oControl, propValue, Nothing)
End If
Next
End If
End Sub
