Hello,

  I am trying to write a simple DLL. For that I go into my Visual C++ 6.0 enviournment. I open a new project as "Win32 Dynamic-Link Library". I add my source and header files to it. I can compile & link fine. I also get my dll file in the Debug directory. Now the problem is, there is no lib file in the Debug directory. I need the lib file for my application to run. How do I get the project to make the lib file? Thanks.

Are you sure?  The default for a DLL project is to produce an IMPORT LIB file in the same folder as the resultant DLL.  Perhaps your EXPLORER is hiding .lib file??

Try looking with a CMD/COMMAND window and use DIR /A *.lib.

You have to export a symbol in order to get a lib file.

Just add

extern "C" __declspec ( dllexport) Test () {}

and you will get one.

jkr,

Good point!!  

I guess I (perhaps mistakenly) assumed that the DLL had EXPORTS.  But you are right, no exports, no lib, no useful DLL either.

YES, I got it after exporting the variables and functions. Thanks.
