Hello,

I have been trying to create properties extender for Solution Explorer items
in VS.NET 2003. The items i am interested in are solution, solution files,
project, project files and project folders.

It appears while some of the items can be extended (most notable solution as
presented in MS Solution Extender Sample; also CSharp/VB projects), there is
no way to extend others - for example C++ projects or files, etc. The
registration entries were made in the same manner for CATIDs that work and
for those that did not (under .../Visual Studio/7.1/Extenders hive).

I have tried to use any CATID i could find for that purpose (started from
prjCATIDProject = "{610D4614-D0D5-11D2-8599-006097C68E81}",
prjCATIDProjectItem = "{610D4615-D0D5-11D2-8599-006097C68E81}"), but i could
not either make it work or understand why it does.

The impressions i had is that some categories are just not implemented.

It would be very helpful to have some hint where those categories documented
and how one can make it work.

If MS (or anyone) is interested in repro case, i will semd it up at first
notice.

Thank you beforehand,

WBR, Curedone

Here are the CATIDs I use for an add-in that includes extenders for VC
projects, VC filters, and VC files:

String VCFileCATID = "{610D461F-D0D5-11D2-8599-006097C68E81}";
String VCFileBrowseCATID = "{EE8299C9-19B6-4F20-ABEA-E1FD9A33B683}";
String VCFilterCATID = "{610D461D-D0D5-11D2-8599-006097C68E81}";
String VCFilterBrowseCATID = "{EE8299CA-19B6-4F20-ABEA-E1FD9A33B683}";
String VCProjectCATID = "{610D461E-D0D5-11D2-8599-006097C68E81}";
String VCProjectBrowseCATID = "{EE8299CB-19B6-4F20-ABEA-E1FD9A33B683}";
String SolutionCATID = "{52AEFF70-BBD8-11D2-8598-006097C68E81}";
String SolutionBrowseCATID = "{A2392464-7C22-11D3-BDCA-00C04F688E50}";

Note that it is the browse CATIDs you want if you are trying extend the
properties displayed when a solution, VC project, VC filter, or VC file
is selected in the Solution Explorer.

Hi Bob,

Thanks for the post about the CATID's - they were very helpful!

I'm working on extending the properties available within C# projects, and as
such I'm using the prjCATIDCSharpProjectBrowseObject = {4EF9F003-DE95-4d60-
96B0-212979F2A857}

Everything works fine re: CanExtend gets fired when on a C# project and I
return true after a quick test of the inbound ExtenderCATID.

Next I implemented the GetExtender method...

public object GetExtender(string ExtenderCATID, string ExtenderName, object
ExtendeeObject, EnvDTE.IExtenderSite ExtenderSite, int Cookie)

...and this is where I'm running into troubles - I'm having a hard time
trying to determine what type the ExtendeeObject is. I've tried checking it
against pretty much everything in EnvDTE, EnvDTE80 and the VSLangProjXX DLLs
with no luck.

I have been "cheating" in the meantime by going after the DTE.SelectedItems.
Item(1).Project, however this doesn't feel right since I'm assuming that the
passed in ExtendeeObject has all the information I need.

Can you (or any other generous coder out there) shed some light on what
ExtendeeObject is?
