Hi!
you have to create def file and then use lib /def command for create import library .
for reference see MSDN article:
HOWTO: Create 32-bit Import Libraries Without .OBJs or Source

Hi

Also a possibility is linking the dll at runtime:

in your class where you want to use the dll declare member variables for the functions, e.g.

BYTE (__stdcall* m_lpMyFunction)(int);


.... and a handle for the dll:

HINSTANCE m_hDllInstance;

in your cpp file implement the following (best in the class constructor):

m_hDllInstance=AfxLoadLibrary("YourDll.dll");
if(m_hDllInstance)
{
    m_lpMyFunction=(BYTE (__stdcall*)(int msg))GetProcAddress(m_hDllInstance,"FunctionNameInDll");
}
else
{
    AfxMessageBox("Can't load DLL!");
}


Just look for your .h file of the dll for the correct function definitions

In the 'Link' tab of the 'Project Settings' dialog for the calling program, in the 'Object/library modules edit control you must add the full path for the .LIB file.  You said you did not get a .LIB soooo.... if you will send me your EMAIL address (I'm millercg@teleport.com) and I will send you two projects; one for a working 'Caller' and one for a DLL that it will call.

Shay----->  You have asked 95 questions at this site, and only awarded 53 of them....  this is totally against the Guidelines of this site.  Please return to them and update/finalize them this week.  The list is below.  Of these 53 awarded, there are 7 questions that are -1 user id problems which we will need to manually correct.  Please accept the first correct response in each of them and award the experts who helped you with the deserved "A" grade, or comments if less than an A as to why.  If you need our help to special handle any of these, let us know that as well via comment here.  If these are not finalized this week, I will contact Administration for further action.  Please click the HELP DESK link on the left for the rules of engagement here (Guidelines, Member Agreement and Question/Answer process).

I also noticed that a number of your questions are less than 50 points, which is the recommended value for EASY questions, with 300 points the maximum.  To draw additional attention, you can always increase their values without our assistance.

I have asked Administration to Email you in these regards.  I also noticed several other things I'd like to bring to you attention.  There are some that you did award with "C" grades, and no comment as to why.  Also, some of your questions have had zero response, and that is likely for two reasons:  Poor closure on open items and poor grades.  I think you'll agree, epecially given the number of questions you've asked here, that experts here take great pride in their work, and deserve "A" grades and responses to all help they've given you.

EXPERTS -->  In the event any of these items remain open at the end of this week, I will finalize them and look to you for guidance on the fair results.  As always, we very much appreciate your willingness to help and the excellent support you all give.

Thanks,
