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:

};

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
