Hi all,
I want to import a C Lib file and a Header file as Delphi units to use in
projects... How do I go about it? Any help is appreciated... Thanx in
advance...

You cannot use the LIB file (get the DLL, if any, from which it was
produced.). The header file needs to be translated into a Pascal unit
for Delphi to be able to use it. Get Dr Bob's HeadConv program. This
will do most of the job for you - but you might have to make manual
adjustments. HeadConv presumes that the header file is an interface
to a DLL. If there is no DLL, then you are stuck.

I'm pretty sure your LIB file won't be compatible with Delphi. You'll
probably need to create a new library in Delphi. If this is a third-party
library, you should contact them to see if they have Delphi-compatible
libraries.
As for the H file, you'll need to create a PAS file and write Pascal code
which defines the same types and constants. Someone may have a utility to
do this, but I'm not aware of it. Of course, I'm not aware of too many
things... ;-).

Delphi cannot read C headers, so you have to translate the header to a
Delphi import unit (all the API units like ShellAPI or Windows are import
units). You do not need the LIB file (i hope this is a DLL link library,
not a collection of OBJ files).

There are tools around that try to automate the translation:

http://www.drbob42.com

They can do some of the grunt work but some manual post-processing is
usually needed. You can find some general information on how to translate C
to pascal on the Delphi Jedi site: http://www.delphi-jedi.org.
