The item data contains information about a particular application and its icon. The ITEMDATA structure has the following form:
struct tagITEMDATA {
POINT pt;
WORD iIcon;
WORD cbResource;
WORD cbANDPlane;
WORD cbXORPlane;
WORD pHeader;
WORD pANDPlane;
WORD pXORPlane;
WORD pName;
WORD pCommand;
WORD pIconPath;
};Following are the members in the ITEMDATA structure:
pt
Specifies the coordinates for the lower-left corner of an icon in the group window. It is a point structure.
iIcon
Specifies the index value for an icon. This value indicates the position of the icon in an executable file.
cbResource
Specifies the count of bytes in the icon resource, which appears in the executable file for the application.
cbANDPlane
Specifies the count of bytes in the AND mask for the icon.
cbXORPlane
Specifies the count of bytes in the XOR mask for the icon.
pHeader
Specifies an offset from the beginning of the group file to the resource header for the icon.
pANDPlane
Specifies an offset from the beginning of the group file to the AND mask for the icon.
pXORPlane
Specifies an offset from the beginning of the group file to the XOR mask for the icon.
pName
Specifies an offset from the beginning of the group file to a string that specifies the item name.
pCommand
Specifies an offset from the beginning of the group file to a string that specifies the name of the executable file containing the application and the icon resource(s).
pIconPath
Specifies an offset from the beginning of the group file to a string that specifies the path where the executable file is located. This path can be used to extract icon data from an executable file.
