I have the following code

#DEFINE HKEY_CLASSES_ROOT -2147483648

CLEAR

SET PROCEDURE TO Registry.prg
oReg = CREATEOBJECT('registry')

oDll = CREATEOBJECT("MyDll.MyClass")
cClassId = COMCLASSINFO(oDll, 4)
cClassId = "CLSID\" + cClassId + "\InProcServer32"

? oReg.ReadRegistryString(HKEY_CLASSES_ROOT, cClassId, "Default")
? oReg.ReadRegistryString(HKEY_CLASSES_ROOT, cClassId, "ThreadingModel")

RETURN

In the registry, the default value contains the full path and name of
my DLL, which is what I want.

In the 2 calls to ReadRegistryString above, the ThreadingModel is returned
fine, but with the default key, I get NULL returned. Is there some way of
acessing the Default key?
