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.
