Using Delphi 2.0 DLL in Visual C++ 4.1 EXE

I've got a DLL creating with Delphi 2.0, and I'd like to use this DLL in a
program created with Visual C++ 4.1.

I have to created a .LIB file to do it, but I can't find a utility to create a
LIB file from the DLL. I've checked Delphi and VC++ for a util.

Anybody got any hints?

You checked out the lib utility?

You don't need no LIB file. All you have to do is go to View|Project Source,
then replace the keyword program with library, create export clauses for all
functions that you want to export (don't forget to specify the correct calling
convention), and Delphi will create the DLL for you. Make sure to read the
Delphi documentation about DLL's before diving into this.

If you're referring to the one that came with VC++, yeah, I did. The help is
a couple of paragraphs and isn't real helpful. Borland used to ship IMPLIBW
with its compilers, but doesn't any longer.

Can TDUMP.EXE do this? (I've no idea, thought it's worth
a shot.)

I have the last version of Borland C++ and it still ships with IMPLIB.
I don't have VC++ 4.1, but I'm sure it also ships with IMPLIB.

If all else fails, I guess you could use the IMPORTS mechanism in your
.def file, but I don't like that method myself.

Good luck,

Read my original post again. I said that I *already* have the DLL compiled.
I need to create a LIB file (whether you think I do or not). So, knowing
these two facts, can anybody tell me how to make a LIB file for this DLL so I
can link it into my C++ program?

Re:Using Delphi 2.0 DLL in Visual C++ 4.1 EXE

We spent a couple of hours figuring this out last week. First create
a DEF file and then use VC++ LIB utility to create the LIB. Something
like LIB /IMPORT:MYFILE.DEF /OUT:MYFILE.LIB. I used the
BC++ IMPDEF utility to create the DEF file - I'm not sure what
equivalent there is in Delphi or VC++. If you do have BC++, don't use
IMPLIB to create the LIB - VC++ won't recognize it.

Mark.
