CLSID$

Previous pageReturn to chapter overviewNext page

 

Description

 

Return a 16-byte GUID string (128-bit GUID format string) containing a CLSID associated with a unique ProgramID string of a COM object or component.

 

 

Syntax

 

s = CLSID$(ProgramId)

 

Returns

 

String

 

Parameters

 

Name

Type

Optional

Meaning

ProgramId

String

No

A string representing the program id of a COM object/component.

 

The ProgramID parameter is not case-sensitive, so "MSAGENT.CONTROL.2", "MSAgent.Control.2" and "msagent.control.2" all refer to the same COM object/component.

 

Remarks

 

A CLSID string is a 128-bit (16-byte) binary string representing the GUID or UUID of a COM object/component.

 

A CLSID string is not in a human-readable format.

To convert the binary CLSID string into human-readable GUID/UUID format, use the GUIDTXT$ function.

 

CLSID$ is the complement to the PROGID$ function.

 

If the ProgramID cannot be found, or if any error occurs during the lookup and conversion process, CLSID$ will return an empty string.
