Thanks & Regards

Do you mean you want to use the variable, defined in static Library, in the Dll? If so no need of dll(ex/im)port declarators, declare the variable as extern in Dll and link the static library to the DLL.

I have lib print.lib .Here I have some data which I need to transfer to clib.lib.. But clib.lib gets linked to a dll alm.dll..
I have declared a variable int aprint; in print.lib. I was able to compile successfully.
I declared the same variable as extern in clib.lib, I was able to compile successfully.
When when I try to compile alm.dll I am getting the linker error..
Plz suggest me how to resolve this error.

again vague... form of description,
Now the scenario is not which you explained,
int aprint; is defined in print.lib;
extern int aprint; is declared in clib.lib;
now assuming alm.dll is not using the variable directly, if you link to clib.lib, you need to link to print.lib also to resolve the symbol aprint;
if you want to use aprint in alm.dll also, then extern declaration is need there also, you need to link all the three libs.

I linked the two libs in the dll as you said. But same error.
|

|

 what's the error, why don't you post the link error full length.

Usually we don't *send* code, but for noble causes (like the task is urgent, it is a homework, etc.,) we can send, I guess.

I'm using Visual C++ 6.0 - basically new to MFC programming
I don't understand the difference between
MessageBox()
and
AfxMessageBox()
Don't they both do the same thing?
Thanks ahead of time

|

AFAIK, MessageBox belongs to Windows API
AfxMessageBox is a global function in MFC.
There could be other differences as well relating with the parameters being passed to the function and the way they are implemented.
Somethings seem HARD to do, until we know how to do them.
