Provides access to members that work with globally unique identifier objects.
When To Use
Use the IUID interface to set the value of a UID object, set the subtype of the UID object, generate a new globally unique value, or compare two UID objects.
Members
| Name | Description | |
|---|---|---|
 |
Compare | Indicates if the two UID objects represent the same globally unique identifier. |
|
Generate | Creates a new globally unique value for the UID object. |
 |
SubType | The subtype of the UID object. |
|
Value | The value of the UID object. |
IUID.Compare Method
Indicates if the two UID objects represent the same globally unique identifier.
Public Function Compare ( _
ByVal otherID As UID _
) As Boolean
public bool Compare (
UID otherID
);
Description
Returns a boolean indicating whether the specified UID object represents the same globally unique value (GUID) as this UID object.
IUID.Generate Method
Creates a new globally unique value for the UID object.
Public Sub Generate ( _
)
public void Generate (
);
Description
Creates a new globally unique value (GUID) for the UID object. This is a 128-bit integer used for CLSIDs and interface identifiers.
IUID.SubType Property
The subtype of the UID object.
Public Property SubType As Integer
public int SubType {get; set;}
Description
Use the SubType property when working with classes that implement ICommandSubType that have multiple commands within a single class.
IUID.Value Property
The value of the UID object.
Public Property Value As Object
public object Value {get; set;}
Remarks
The Value property is a string representing either the CLSID or ProgID of an interface or coclass.
COM interfaces and coclasses are identified by a globally unique identifier (GUID). The GUID for an interface is called an interface ID (IID). The GUID for a coclass is called class ID (CLSID). A ProgID is a text alias for a CLSID; the ProgID is a string composed of the project name and the class name of the coclass.
ArcGIS for Desktop developers can find the CLSID, ProgID, and subtype of a built-in command, menu, or toolbar in ArcMap or ArcCatalog, in the following technical documents:ArcGIS Developer Help for Desktop developers > General reference > Names and IDs > ArcMap commandsArcGIS Developer Help for Desktop developers > Technical General reference > Names and IDs > ArcCatalog commands
