Hi,
I want to import a class from a dll dynamiclly by using LoadLibrary(DLLFile)
and not by using Project->Settings->Link....
Is it the same as loading regular function from a dll(By getting a pointer
to that function)?
for example,if in my dll the function looks like this:
in my dll.h file:
#define TCPDLL_API __declspec(dllexport)
#ifdef __cplusplus
extern "C" {
#endif
TCPDLL_API ERROR_CODES FLRInitializeConnections(IPStruct *Server,int num_of_radars);
#ifdef __cplusplus
}
#endif
and in my dll.cpp file:
TCPDLL_API ERROR_CODES FLRInitializeConnections(IPStruct *Server , int num_of_radars)
{
}
now,when i want to use the function :
in my app.h:
typedef ERROR_CODES (*FLRInitializeConnections_PROC )(IPStruct*,int);
HINSTANCE hLib;
FLRInitializeConnections_PROC FLRInitializeConnections;
and in my app.cpp:
hLib = LoadLibrary(DLL name);
FLRInitializeConnections = (FLRInitializeConnections_PROC)GetProcAddress(hLib,"FLRInitializeConnections");
Now i can call the function from the dll.
My question is - in order to use a class from a dll , what should i do?
Do i need to get a pointer to that class or can i load the dll and make instance of that class in the regular way?
With best regards,
Eli

You should load the dll using LoadLibrary and call the DllUnregisterServer function and then unload the dll.

IN Continuation With Mr Santosh!
you must call CoIntialize(NULL) before Calling DllUnregisterServer

yes Santosh, if you see defination of any DllUnregisterServer
STDAPI DllUnregisterServer(void)
{
return _Module.UnregisterServer(TRUE);
}
here DLLUnregisterServer is Using Com Interfaces and to use com interface COM must be Intialised!
Hope, you got my Point!

CoIntialize() is used to Initializes the COM library. That is if you are using any com library functions you do this. But _Module is not created with CoCreateInstance() or something like that. So I don understand the need of CoInitialize() in this scenario.

Hi,
I need some advice/help in writing a program to parse XML file (using DOM) and returning element inside a particular tag. So if I select a tag identified by its tag value, it should give me the element inside that tag.
Appreciate all your help.
Thank you
Ray

Hi All,
I am facing problem of handle leak in my Application.
While using AfxBegin thread creating a worker thread in suspended mode and then resuming the thread using resumethread.
During above process 7 Handles are getting created but when I am exactly closing the thread using PostThreadMessage(WM_QUIT, NULL, NULL) only 5 handles are getting closed. Two handles are not being closed.
The details is like This:
m_pControlThread = AfxBeginThread (
ControlThreadLoop,
( LPVOID )this, THREAD_PRIORITY_NORMAL,
0, CREATE_SUSPENDED
);
m_pControlThread->ResumeThread();
from above 7 handles are getting opened.
In Destructor Closing like this:
if (m_pControlThread)
{
m_pControlThread->PostThreadMessage(WM_QUIT, NULL, NULL);
WaitForSingleObject( m_pControlThread->m_hThread,
_MESSAGE_TIMEOUT );
delete m_pControlThread;
}
Here only 5 Handles are getting closed...
Where remaining 2 handles are missing .... I am not getting any Idea..
Please suggest..
Thanks,
Jokhan

That could be normal behaviour. Windows likes to keep some handles around to be reused later. The way to check if this is the case is to run and stop your thread multiple times. If the total handle count does not keep climbing you are ok, if it does climb you have a problem.
ie: handle count is 0...7...2...7...2...7...2...7... etc OK
" " " 0...7...2...9...4...11...6...etc Error
