use doevents after

<div>
Depending on what your case is you need to choose which to use. If you use the .Refresh method you will only update the label but if you use the DoEvents method you will update all controls that are visible. DoEvents lets the system (Windows) take over for a period of time to do some system work and when it has finished that it will return the control to the application. A refresh event can be stored in the system list of things to do and that's why your control will be updated after DoEvents.<br />
<br />
If you have a application that will run for several minutes you should use DoEvents because then the application will not slow down so much during time, otherwise your app will consume the power from the system.

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
