In VC6.0: Tools -> Options -> Directories -> show directories for:
a) include files (the include dir: D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\include )
b) libraru files (the lib dir, D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\lib )
Step 4
-----------------
Copy the following files from Transport Tycoon Deluxe to the data folder
sample.cat
trg1r.grf
trgcr.grf
trghr.grf
trgir.grf
trgtr.grf
(Alternatively you can use the TTD GRF files from the DOS version: TRG1.GRF, TRGC.GRF, TRGH.GRF, TRGI.GRF, TRGT.GRF. Those filenames have to be uppercase to be detected correctly. A few minor graphical glitches with the DOS graphics remain. E.g. the autorail button in the rail toolbar doesn't look as nice as with the Windows graphics.)
