Returns or sets the background color of the viewport.


object.BackColor [= color]

The BackColor property syntax has these parts:

Part Description
object An object expression that evaluates to a SmartViewport object.
color A value or constant that determines the background color of an object as described in Settings.


Visual Basic uses the Microsoft Windows operating environment red-green-blue (RGB) color scheme. The settings for color are:

Setting Description
Normal RGB colors Colors specified by using the Color palette or by using the RGB or QBColor functions in code.
System default colors Colors specified by system color constants listed in the Visual Basic (VB) object library in the Object Browser. The Windows operating environment substitutes the user's choices as specified in the Control Panel settings.

At design time, the default BackColor for the SmartViewport is set to the system default color specified by the constant vbButtonFace.


The valid range for a normal RGB color is 0 to 16,777,215 (&HFFFFFF). The high byte of a number in this range equals 0; the lower 3 bytes, from least to most significant byte, determine the amount of red, green, and blue, respectively. The red, green, and blue components are each represented by a number between 0 and 255 (&HFF). If the high byte isn't 0, Visual Basic uses the system colors, as defined in the user's Control Panel settings and by constants listed in the Visual Basic (VB) object library in the Object Browser.

The BackColor property affects all SmartViewport areas except the scrolling bars. When both scroll bars are visible, you can specify what color the bottom-right corner should have through property CornerColor.
