Property Dialogs
Depending on the development environment used, the steps necessary to modify the control properties vary. The properties supported by the control can be displayed in a variety of ways. See your development environment's documentation for specific instructions.
Usually, development tools allow access to the Property Pages implemented by a control. For example, Visual Basic allows you to right-click on the control in design mode. By selecting Properties from the popup menu presented, the properties can be accessed using the Property Pages provided by the control. The following tabs are offered by this property dialog. Additional tabs may be added to the dialog by your development tool.
Each tab and associated page allows a set of properties to be manipulated. All properties are labeled using the property name. Detailed descriptions can be found in the on-line help.
Most pages offer on-line help by clicking on the Help button. This help button may not be displayed when using certain development environments. Other means may be available to view the product's on-line help.

Property Pages
There are two types of property pages.
Property List
This type shows a number of properties using categories (such as Appearance, Behavior, Colors, etc.).
By clicking on a property, the property can be edited. Using the TAB (or SHIFT+TAB) key the next (or previous) property can be edited or simply click on another property.
Double-click on the description of a property to display the complete help information or right-click on the property dialog for a help menu.
Custom Page
The second property page type displays a page specific to the object being changed. Please see the page's help information.
Color Properties
When clicking on a property representing a color value, a combo box is displayed which shows the available system colors as defined using Control Panel and also the basic colors. A new color value can be selected from the choices offered or a new color value can be entered. The following syntax is accepted:
| &H00bbggrr& | A hexadecimal number (Visual Basic style) |
| 0x00bbggrr | A hexadecimal number (C/C++ style) |
| decimal | A decimal value, the decimal equivalent of a hexadecimal color value |
| bb = blue component rr = red component gg = green component |
Example:
&H00FF0000& Blue
0x0000ff00 Green
The display format of color values can be modified using the Options page.
Picture Properties
A Picture property can be defined by clicking on the 
bitmap of the cell. This displays a dialog that is used to load a bitmap, icon or metafile. Some properties only allow bitmaps or only icons.
Once a file has been loaded, the image is saved along with the control properties and the file is no longer required.
Picture properties display (None), (Bitmap), (Metafile), (Icon) or (Invalid Type), depending on the graphic type loaded.
To clear a Picture property click on the bitmap of the cell, then click Cancel on the resulting dialog. This will clear the Picture property.
Font Properties
A Font property can be defined by clicking on the bitmap of the cell. This displays a dialog that is used to define the attributes of the font.
