Description

 

Return the unique PROGID string (text) associated with a unique CLSID string of a COM object or component.

 

Syntax

 

s = PROGID$(ClassId)

 

Returns

 

String

 

Parameters

 

 

Remarks

 

You convert the 16-byte (128-bit) binary class ID of a COM object/component into a PROGID string with the PROGID$ function.

 

PROGID$ takes the (16-byte) binary string ClassID$ representing the GUID or UUID of a COM object/component, and examines the system registry in order to determine the PROGID string associated with the ClassID$ string. ClassID$ may be a dynamic string or fixed-length string of at least 16 bytes, or (typically) a GUID variable.

 

If the ClassID cannot be found, or any error occurs in the lookup process, PROGID$ will return an empty string.

 

PROGID$ is the complement to the CLSID$ function. Using these two functions together, it is possible to extract the precise capitalization of the PROGID from the system registry. See the example below.
