Two DLLs and one app

How can I use more than one dll in my app.
In the main prg file I add this line
When I call something from A.DLL all is ok. When I call something from B.DLL it doesn’t show. Do I have to use SetResource(cDllName) before and after each call to B.DLL. Is there a way to make my app id both dlls automatically?
Thanks

Greetins Kronos,
try this ...
hAdll:= LoadLibrary("A.dll")
hBdll:= LoadLibrary("B.dll")
....
[the body of your aplication]
...
// just before the end of your aplication or when u wish to liberate from
// memory the loaded libraries write this ...
FreeLibrary(oAdll)
FreeLibrary(oBdll)
// Hope it helps.
Nos leemos!!

Thanks for the reply. It still isn't sorking. I have two choices.
A)Merge the two dlls into one, or
B)use Setresource(cDllName) before and after calls to that dll.
DLL B is a general perpuse one that holds resources for the user login/out and movement tracking system. It's small so I guess I'll mege it into DLL A which is a program specific one.

try this:LOCAL hRes1,hRes2
SET RESOURCE TO A.DLL
hRes1 := GetResources()
....
... USING A.DLL RESOURCES
...
SET RESOURCES TO B.DLL
hRes2 := GetResources()
...
... USING B.DLL RESOURCES
...
SetResouces(hRes1)
...
... USING A.DLL
...
SetResouces(hRes2)
...
... USING B.DLL
...
ETC...

I use FW 2.4, Clipper 5.3e and Blinker 7.0.
I needed 6 DLL's files to store all my screens. And that was to much to handle properly.
So what did I do ?
In Workshop 4.5, I saved all my DLL-files as RES-files.
I implimented my RES-files into my LNK-script like this :
---------------------------
OUTPUT APLLIC.EXE
BLINKER INCREMENTAL OFF
BLINKER CLIPPER SYMBOL OFF
BLINKER EXECUTABLE ALIGNMENT 128
PACKCODE
PACKDATA

FI obj2
....
FI objZ

segment 'SORTOF_TEXT' nondiscardable
segment 'STACK_TEXT' nondiscardable
DEFEND
LIB yourlibs
LIB oFive16,oFive16C
LIB WINAPI
NO BELL
---------------------------
That is how my LNK-script looks like.
And it just works fine.
Also, you need to delete all your "SET RESOURCE TO" in your PRG-files.
the '->' in the LNK-script are just signs to put the attention on, of course.
Good luck.
