Hi all,

I create a MFC DLL "Static" and with wizard I add a dialog and "Microsoft web browser" ActiveX in this dialog, also I create a class for this Dialog.

All I want here to call this Dll from a Win32 app "normal c++" and load this Dialog into the Main UI, But I got an Assertion error.

Snippet of Code:

//////////////
// DLL
//////////////
//.h
class CShofhaMFCStaticApp : public CWinApp
{
public:
CShofhaMFCStaticApp();
void CreateBrowser(HWND hWnd);

// Overrides
public:
virtual BOOL InitInstance();
DECLARE_MESSAGE_MAP()

};
extern "C" __declspec(dllexport) void CreateBrowserEx(HWND hWnd);
//.cpp
ShofhaBrowser *m_pMyDlg;
extern "C" __declspec(dllexport) void CreateBrowserEx(HWND hWnd);
CShofhaMFCStaticApp* thisDLL;
__declspec(dllexport) void CreateBrowserEx(HWND hWnd)
{
thisDLL->CreateBrowser(hWnd);
}
CShofhaMFCStaticApp::CShofhaMFCStaticApp()
{
thisDLL = this;
m_pMyDlg = NULL;
}
class tempRoutingFrame {

CFrameWnd* m_pFrame ;

public:

tempRoutingFrame(CFrameWnd * pWnd= NULL)
{
// Save current value
m_pFrame = AfxGetThreadState()->m_pRoutingFrame;
// Set to value passed in. NULL by default.
AfxGetThreadState()->m_pRoutingFrame = pWnd;
}
~tempRoutingFrame()
{
// Restore m_pRoutingFrame to original value.
AfxGetThreadState()->m_pRoutingFrame = m_pFrame;
}

};

void CShofhaMFCStaticApp::CreateBrowser(HWND hWnd)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());

if(m_pMyDlg == NULL)
{ 
CWnd *pParent = CWnd::FromHandle(hWnd);
m_pMyDlg = new ShofhaBrowser(pParent);
m_pMyDlg->Create(IDD_MAIN, pParent); 
m_pMyDlg->ShowWindow(SW_SHOW); 
}
}
//and The dialog
class ShofhaBrowser : public CDialog
{
DECLARE_DYNAMIC(ShofhaBrowser)

public:
ShofhaBrowser(CWnd* pParent = NULL); // standard constructor
virtual ~ShofhaBrowser();

virtual void OnFinalRelease();

// Dialog Data
enum { IDD = IDD_MAIN };

protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support

DECLARE_MESSAGE_MAP()
DECLARE_DISPATCH_MAP()
DECLARE_INTERFACE_MAP()
public:
CExplorer1 m_browser;
};
//////////////
// Exe
//////////////
void CMFCtestApp::OnAppAbout()
{
/* get handle to dll */ 
HINSTANCE hGetProcIDDLL = LoadLibrary(TEXT("..\\ShofhaMFCStatic.dll")); 

/* get pointer to the function in the dll*/ 
FARPROC lpfnGetProcessID = GetProcAddress(HMODULE (hGetProcIDDLL),"CreateBrowserEx"); 

/* 
Define the Function in the DLL for reuse. This is just prototyping the dll's function. 
A mock of it. Use "stdcall" for maximum compatibility. 
*/ 
typedef BOOL (__stdcall * pICFUNC)(HWND); 

pICFUNC MyFunction; 
MyFunction = pICFUNC(lpfnGetProcessID); 

HWND fWindow; // Window handle of the window you want to get

fWindow = FindWindow(NULL, _T("Window_title")); // Find the window

///* The actual call to the function contained in the dll */ 
BOOL intMyReturnVal = MyFunction(fWindow); 

/* Release the Dll */ 
FreeLibrary(hGetProcIDDLL);
}

Please Help :)
Thanks in advance

It is a static DLL "MFC libraries compiled in it"?? please Explain

Thanks in advance

It doesn't matter if the dlls are static or not. The application program has to initialize the MFC library. Create a console program that supports MFC and you will see how that is done. I was able to do that with VC++ 6.0, but I don't know if that option is still available in more recent versions of the compiler.
