Attributes and elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute Description
guid Required. GUID of the GUID/ID command identifier.

The guid attribute for a bitmap is not associated with any VSPackage or other command group. It should be unique to the bitmap definition and should not be used for any other purpose.
resID ID of the GUID/ID command identifier. Either the resID or the href attribute is required.

The resID attribute is an integer resource ID that determines the bitmap strip that is to be loaded during command table merging. When the command table is being loaded, the bitmaps specified by the resource ID will be loaded from the resource of the same module.
usedList Required if the resID attribute is present. Selects the available images in the bitmap strip.
href Path to the bitmap. Either the resID or the href attribute is required.

The include path is searched for the indicated image file, which is embedded in the resulting binary. During the command table merge, the image is copied and no additional resource lookup or load is required. If the usedList attribute is not present, all images in the strip are available. Note: Images may be supplied in one of several formats that include .bmp, .png, and .gif. Earlier versions of the compiler did not support 32-bit bitmap images that had alpha information for partial transparency. The workaround for these versions is to use the .png format.
Condition Optional. See Conditional attributes.

Child elements

None.

Parent elements

Element Description

Example

<Bitmap guid="guidWidgetIcons" href="WidgetToolbarIcons_32.bmp" />

  usedList="1, 2, 3, 4"/>
