Hi All, 
I have commercial product, which contains some dll files. There are some
C header files and lib libraries files too, but I have not source codes.
I know how write programs with C, it's ease include *.h and link library
to my project.

How can I make this with Delphi? Should I make myself some unit with
declaration or something else?
Please help me.

Thank you for all ideas          Martin

Hi,

You will have to create your own import unit. Don't forget to use the
"stdcall" argument while calling c dll's.

Check out HeadConv, my freeware C DLL header converter that I turned into a
command-line version recently (goto http://www.drbob42.com/ftp/headconv.zip).

HeadConv has full support for functions and procedures, argument and return 
types (128 custom type conversions) and generates implicit Delphi import units. 
The command-line HeadConv supports for typedefs, structs, unions, enums and 
conditional compilations. HeadConv is not targeted to do the conversion 100% 
on its own, rather it will assist you in converting the C DLL header files!
