About cowhere

I have been wanting a utility to display the path of a COM component given a ProgID. I was spelunking for something else and I ran across Hugh Brown's CoWhereIs utility. I didn't find the source, so I whipped a quick version of a similar utility, cowhere. 'cowhere' will display information in the registry about the COM component represented by the CLSID. It will also check to see if the file containing the component is present.

Usage

cowhere <clsid> [/create]

where <clsid> can be either a ProgID or a CLSID GUID and /create attempts to instantiate the component.

Examples:

C:\>cowhere word.application
CLSID: {000209FF-0000-0000-C000-000000000046} "Microsoft Word"
  InprocHandler32: "ole32.dll"
  InProcServer32: 
   "E:\Program Files\Common Files\Symantec Shared\Script Blocking\scrblock.dll"
  LocalServer32: "E:\PROGRA~1\MICROS~3\Office\WINWORD.EXE  
    /Automation" ("E:\Program Files\Microsoft Office\Office\WINWORD.EXE  ")
      [LocalServer32]: (value type not supported)
  ProgID: "Word.Application.9"
  VersionIndependentProgID: "Word.Application"


C:\>cowhere {00000293-0000-0010-8000-00AA006D2EA4}
CLSID: {00000293-0000-0010-8000-00AA006D2EA4} "ADODB.Connection"
  InprocServer32: "E:\Program Files\Common Files\System\ADO\msado10.dll"
      [ThreadingModel]: "Apartment"
  ProgID: "ADODB.Connection.1"

Current limitations

This should work under 95/98/ME/W2K/XP, but has only been tested under NT/W2K/XP. If anyone else could test it under 95/98/ME and give me feedback, I would appreciate it. I updated the problem with GetLongPathName so that it works on NT, where this kernel32 proc is not available.
