Visual Basic 2010 Progress Bar Control

VB 2010 Progress bar - Visual Basic Online Course

Using the ProgressBar control Example :

Create New Windows Project
Button1
ProgressBar1

- Logic :

We will generate 4 Message Boxes by clicking the Button1 Control and every time a message box 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.
