Does NSIS support auto generate csid ?

I'm going to add a custom toolbar button on existing IE.
Adding custom toolbar button on IE is just adding some kinds of registries.

Does NSIS support generate a unique csid ?

I don't know what a csid is, but if its anything like a GUID, use http://nsis.sourceforge.net/Create_a...que_Identifier
and

do you mean CLSID by any chance?

Anders is right!!! It should be GUID.

Thanks anyway!!

I think the GUID is used as an identifier of your application, so it's a fixed compile-time value and should not be generated on run-time.

Yes right, GUID is used to identify my application. In my case of creating a custom toolbar button for IE browser. As from microsoft MSDN document

http://msdn2.microsoft.com/en-us/library/aa753588(VS.85).aspx

of adding custom toolbar button for IE, it is required to add a new GUID.

In creating my installer from NSIS, Ive to generate a new GUID and then add other necessary registries.
