I have written a Regular DLL with many Ex****t Functions and one CALLBACK
fun
ction .
The callback function declared in the .cpp file of the Regular DLL is as
fol
lows:
typedef BOOL (CALLBACK* ExProcessMessage)(UINT msg, LPVOID lpParam);
//
ExProcessMessage MyProcMsg;
----------------------------------------------------------------------------
--------------------
I have written an MFC Application which is dynamically linked to this
Regula
r DLL.
In the MFC Application (SDI Application with DOC/VIEW sup****t) , I also
use
threading functionalities.
In the MFC Application I have declared a global function as a CALLBACK
funct
ion as follows:
BOOL CALLBACK OnCMFMessage(UINT msg, LPVOID lpParam1);
I initilaise the address of this function to the pointer varaible declared
i
n DLL (MyProcMsg) as follows in my MFC App code:
InitializeCB((long)&OnCMFMessage); -- (whereas the InitializeCB is a
ex****t
function in DLL to initialise the callback function pointer)
----------------------------
Now the problem is , when I call the CALLBACK function (OnCMFMessage) from
m
y DLL by using the function pointer , the callbcak function is not at all
ca
lled. What could be the reason?????
But when I use the as said above with a Win32 application, it worked fine.
M
y callbcak is called. And I got the desired result.
The problem was only with the MFC App which I said above.
