Using SaEzTwain in a multi DLL Project gets Unresolved External errors

When I try to compile the data dll I get these errors:

Unresolved External TWAIN_SETHIDEUI in SaEzTwainCl.obj
Unresolved External TWAIN_ACQUIRETOCLIPBOARD in SaEzTwainCl.obj
Unresolved External TWAIN_GETRESULTCODE in SaEzTwainCl.obj
Unresolved External TWAIN_GETCONDITIONCODE in SaEzTwainCl.obj
Unresolved External TWAIN_OPENDEFAULTSOURCE in SaEzTwainCl.obj
Unresolved External TWAIN_GETRESULTCODE in SaEzTwainCl.obj
Unresolved External TWAIN_GETCONDITIONCODE in SaEzTwainCl.obj
Unresolved External TWAIN_REPORTLASTERROR in SaEzTwainCl.obj
Unresolved External TWAIN_STATE in SaEzTwainCl.obj
Unresolved External TWAIN_LOADSOURCEMANAGER in SaEzTwainCl.obj
Unresolved External TWAIN_REGISTERAPP in SaEzTwainCl.obj
Unresolved External TWAIN_ISAVAILABLE in SaEzTwainCl.obj

I am obviously doing something wrong. Is there anyone who can explain to me how to implement SaEzTwain in a multidll application?
I have no problem using the SaEzTwain example.

In the Project are you including an SaEzTwain.LIB file made from the SaEzTwain.DLL (using Tools LibMaker)?

Or in the Modules List you could add External Dynamic Link Library with file name SaEzTwain.LIB. (If you specify the DLL it will NOT work)

For the Linker to figure out external DLL procedures it needs the matching LIB to lookup the exact case of the procedure names.

Thank you Carl

I included EzTw32.lib in the libraries for the data DLL, and no more errors.
Thanks…
