Hi,
Sorry to bother you, but you are the only person I know who knows much
about namespace extensions and it can takes a long time to get an answer
off newsgroups. I never did find anything similar to dumpbin with Watcom,
but I have now switched to MSVC anyway, dumpbin did show that only DllMain
was being exported. Anyway my problem is:
I am trying to make a namespace extension, so far it is basically the same
as the Cabview sample from Microsoft with much stuff removed. My first
problem was that when CreateViewWindow was called all would go well until I
tried to create the Dialog, CreateDialog) would just return a HWND of 0 and
I would get a message from explorer that there was not enough storage to
continue. Because I had not yet implemented EnumIDs I decided to do that.
Now whenever I run the app it just loops through GetDisplayNameOf and
Compare IDs. I have included a file with there functions in the with this
message. I would greatly Appreciate any help!
Thanks,
Daniel Keller
