 Using the ProgressBar control Example :

- Create New Windows Project
- Button1
- ProgressBar1

- Logic :

We will generate 4 MessageBoxes by clicking the Button1 Control and everytime a messagebox shows up, a ProgressBar step will be taken.

Progress Bar Class : In .Net Framework 4.0

A ProgressBar control consists of a window that is filled, by default from left to right, as an operation progresses. The control has a range and a current position.
ProgressBar overrides the metadata of the Maximum property and sets its default to 100. ProgressBar overrides the metadata of the Focusable property and sets its default to false. For more information, see Dependency Properties Overview.

Customizing the ProgressBar Control

To apply the same property settings to multiple Progress Bar controls, use the Style property. You can modify the default ControlTemplate to give the control a unique appearance. For more information about creating a ControlTemplate, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate. To see the parts and states that are specific to the ProgressBar, see ProgressBar Styles and Templates.
Dependency properties for this control might be set by the control’s default style. If a property is set by a default style, the property might change from its default value when the control appears in the application. The default style is determined by which desktop theme is used when the application is running. For more information, see Default WPF Themes.

Note  

Setting a visual property will only have an effect if that property is both present in ProgressBar control's default template and is set by using a TemplateBinding. You can find a list of visual properties in the "Changing the Visual Structure of a Control" section in Customizing the Appearance of an Existing Control by Creating a Control Template. 

How to call a Progress Bar from a Module in VB 2010



In addition to our example about Progress Bar, what if we wanted to code the progress bar to call it from another level [Module Level] !

Create Visual Basic 2010 Windows Form Application
Place a Progressbar (Progressbar1) control on the Form (Form1
Add new Module (Module1)

Code :

Now, run your application and click on any part of the Form1, you will notice that the ProgressBar is working.
