using CMainFrame Object inside MFC Extension DLL

[Wolvorine]

hi,

My project is divided into two different project one is coredll where i am putting different resources and second is the exe project where i have CMainFrame Cview and CDoc classes.

Now i have a situation in which i need to use CMainFrame's user defined function , what would be a good way to communicate with it without using Send Message or post message. Can i get its CMainFram pointer ???

One solution i guess i should put my cmainframe inside dll which i am not interested in doing that ....any other idea???

Pass the CMainFrame pointer to the DLL?

[Wolvorine]

problem is the dll doesnt know the declaration of CMainFrame and telling its header file and cpp file through directory makes more problem for me ..it seems like i am lost.

And what is wrong for you with SendMessage/PostMessage?

And what is wrong for you with SendMessage/PostMessage?

there is nothing wrong with it, i was just wondering if i can do without the send and post messages by using its own object. But i think there is no other way except send /post ...what you think??

I'd implement send/post a registered message.

I did this way:

1 - Define you function in dll (ny parameters)

typedef void (CALLBACK* MYFUNCTION)(int i,float f);
//////////////////////////////////////////////////////////////////////////
2 - in dll .h file declare
public:
void SetMyFunc(MYFUNCTION pProc);
private:
MYFUNCTION m_pMyFunc;
///////////////////////////////////////////////////////////////////////////
in dll .cpp file implement
void CMyDllClass::SetMyFunc(MYFUNCTION pProc)
{
m_pMyFunc=pProc;
}
///////////////////////////////////////////////////////////////////////////
3 - now in MainFrame
.h
public:
static void CALLBACK MyFunction(int i,float f);
private:
CMyDllClass m_DllClass;
///////////////////////////////////////////////////////////////////
.cpp
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;
m_DllClass.SetMyFunc(MyFunction);
return 0;
}
void CMainFrame::MyFunction(int i,float f)
{
CMainFrame* pThisFrame=(CMainFrame*)::AfxGetMainWnd(); //?? or whatever you need
}
////////////////////////////////////////////////////////////////////////
4 - and last when you need to call function from dll just call

m_pMyFunc(1,15.f); //for example

and it will call function in MainFrame
