TabPage objects and UserObjects when they are tab pages
The TabBackColor property allows you to select the color of the tab on the tab page.
Windows XP This property in not supported on Windows XP because the current XP theme controls the appearance of the tab on a tab page.
To add your own colors to the color drop-down list, select Design>Custom Colors before displaying the Properties view.
To set the background color for the tab:
Select the desired tab page on the tab control.
Select the TabPage tab in the Properties view.
Select the desired color in the TabBackColor drop-down list.
You can set the color of the body of the tab page on its General tab.
The TabBackColor property takes a long value (-2 to 16,777,215) that specifies the numerical value of a color. The TabBackColor value is a combination of values for the red, green, and blue components of the color.
If you do not know the long value for the color, choose Design>Custom Colors to determine the red, green, and blue values and then call the RGB function to specify the color in a script. The following example sets blue as the background color for a tab:
tab_1.tabpage_2.TabBackColor = RGB(0, 0, 255)
