How do I use cards.dll from Aonix OA?

How do I use cards.dll from Aonix OA?

[Petter Fryklund]

Does anybody have an Ada spec? How do I tell AO to reference the dll? I
thought that ie

with Interfaces.C;
with System;
package cdt is
function cdtInit (dx, dy : System.Address) return Interfaces.Unsigned_32;
pragma Import (C, cdtInit, External_Name => "cdtInit");
end cdt;

would do the job, but I get a linker errror, not being able to find cdtInit.
Any suggestions?

  If it's not in one of the standard places the linker looks, then you
must tell the linker where to look for it.  I don't seem to find
anything named cdtInit in my OA installation - where is it supposed to be?
Is it something you created?

No, cdtInit is the initialization of cards.dll. I started with that one just
to see if I could use any routine in there. I tried to add the file
cards.dll to the files in the project, but that was obviously not right. I
couldn't fine any instructions on how to tell the linker where to look. Do
you know?

  If cdtInit is an entry point in cards.dll then you need to call the OS
functions (LoadLibraryA et al) to *dynamically* load the DLL and give you
a pointer to cdtInit.  At *link time* cards.dll need not even exist.
You can either code your own OS calls, or find a routine in a .lib
that knows how to do it, and then statically link from that .lib   Where
did cards.dll come from and did it have an associated .lib file?

[Beard, Frank]

You need to find cards.lib.  You add this to the project
just like you add your Ada source files, except using the
"Files of Type:" combo box to select "Library Files (*.lib)".

cards.lib defines the interface to cards.dll.  Once you link
it, the DLL has to be in the same directory as the executable
that loads it, or in the PATH defined in the System Properties
Environment tab (assuming Windows NT/2000).

If you can't find cards.lib, I think your only option is to 
use the LoadLibrary API, but I can't remember.

cards.dll is used by ie solitaire and others games needing a card deck ;-)
It's probably present in most WIndows systems. I'm trying to learn Windows
programming and having some fun while I'm doing it :-) I'm a bridge fanatic.
I have a command line deal generator that I'd like to convert graphics.

I tried to use LoadLibrary in the following example:

cdt_Str : constant String := "C:\WINDOWS\SYSTEM\CARDS.DLL" &
Character'First;

DLL : Hinstance;

....

DLL := LoadLIbrary (cdt_Str);

but this only returned 0, which I assume is no good.

Any suggestions?

I don't know if it's the most direct way, but try this:

  DECLARE
    cdt_Str : Interaces.C.Char_Array := Interfaces.C.To_C(
"C:\WINDOWS\SYSTEM\CARDS.DLL"  );
  BEGIN
    DLL := LoadLibrary( cdt_str(0)'UNCHECKED_ACCESS );
  END;

I haven't tested this, but it is very similar to other code that I use which
does work.
