Deepa via .NET 247

(Type your message here)
Hi,
My app (DLL) that was developed in VC6 is using ddao35u.lib toaccess the Access Database.
When I try to build the same DLL using VC7 I get the followinglinker error.
Any pointers on how to resolve this?
Thanks!

Does your DLL require any registration? If so may be you should re-register
it?
regsvr32 /u [your dll name]
regsvr32 [your dll name]

Not sure whether this helps.

You might need to switch between wchar_t and unsigned short as the default
WCHAR type.

When I had a problem linking on a CString, it was because I was not
linking in the foillowing libraries:

mfc71d.lib
mfcs71d.lib

Make sure that these are being included in your link path. You can
manually specify them from Linker->Input->Additional dependencies.
