How can I create dialog with ActiveX control in MFC supported console application?

Hi,
I writing a console application with MFC support.
I've craeted "CMyDialog : public CDialog" class.
this dialog has an ActiveX control.

When I'm calling CMyDialog.Create(IDD_MYDIALOG) the function failed, and I'm getting the following warning:

First-chance exception in MyApplication.exe (OLE32.DLL): 0xC0000005: Access Violation.
First-chance exception in MyApplication.exe (KERNEL32.DLL): 0x8001010D: (no name).
Warning: CreateDlgControls failed during dialog init.

Can someone help me?

How can I create this dialog sucessfully?

Thanks,
Michael

How did you create your application? Can please explain in more detail what exactly you mean console application with MFC Support?

O.k.

I've created it with Microsoft Visual Stodio 6.
I've created a new console application with the MSDEV wizard, one of the options is: Console Application with MFC support.

actually it adds several MFC header files to the Win32 Console application.

I was able to bring up a dialog box with a webbrowser ActiveX by adding this at the bottom of _tmain

   afxContextIsDLL= FALSE;  // else AfxOleInit fails
   BOOL fRet= AfxOleInit();
   AfxEnableControlContainer();

   CMyDialog dlg;
   theApp.m_pMainWnd= &dlg;
   dlg.DoModal();

I can't find any documentation on afxContextIsDLL or why it has been set to TRUE, but AfxOleInit() must be called and the code in there will short-curcuit if afxContextIsDLL is TRUE.

Dialogs that contain ActiveX controls are more difficult to create indirectly because they require additional information such as license keys and the initial states of properties. See below article:
<MSDN>
HOWTO: Use a Dialog Template to Create a MFC Dialog with an ActiveX Control

Q231591


--------------------------------------------------------------------------------
The information in this article applies to:

The Microsoft Foundation Classes (MFC), included with:
Microsoft Visual C++, 32-bit Editions, versions 4.2, 5.0, 6.0

--------------------------------------------------------------------------------


SUMMARY
It is possible to display a dialog from either a DIALOG resource or from a dialog template in memory. In the latter case, the dialog template is either constructed or loaded into memory and the dialog is created indirectly.

Dialogs that contain ActiveX controls are more difficult to create indirectly because they require additional information such as license keys and the initial states of properties. MFC requires that this additional information be provided as a DLGINIT resource. The Visual C++ resource editor creates this DLGINIT resource in the resource (.rc) file for each dialog containing an ActiveX control.


Both CDialog::CreateIndirect() and CDialog::InitModalIndirect() support using DLGINIT resources with dialog templates in memory. However, the DLGINIT parameter is not documented and by default is set to NULL. The complete prototypes for these functions are:




BOOL CDialog::CreateIndirect(LPCDLGTEMPLATE lpDialogTemplate, CWnd* pParentWnd, void* lpDialogInit, HINSTANCE hInst);

BOOL CDialog::InitModalIndirect(LPCDLGTEMPLATE lpDialogTemplate, CWnd* pParentWnd = NULL,void* lpDialogInit = NULL);

NOTE: Only the versions of these functions which take a LPCDLGTEMPLATE as the first parameter support passing a DLGINIT resource. The versions which take a HGLOBAL parameter do not support DLGINIT resources.



MORE INFORMATION
The following source shows how to load a DIALOG resource from memory and display it indirectly using a dialog template in memory. This function also uses the DLGINIT resource and will work with DIALOG resources that contain ActiveX controls.



void CMainFrame::OnMyModalDialogIndirect()
{
     //Load DLGTEMPLATE
     DLGTEMPLATE* pTemplate;
 
     HINSTANCE hInst= AfxFindResourceHandle(
                            MAKEINTRESOURCE(IDD_INDIRECT),RT_DIALOG);
     
     if (hInst == NULL)
     {
          TRACE("Cound not find resource in resource chain");
          ASSERT(FALSE);
          return;
     }
 
     HRSRC hRsrc = ::FindResource(hInst, MAKEINTRESOURCE(IDD_INDIRECT),
          RT_DIALOG);
     ASSERT(hRsrc != NULL);

     HGLOBAL hTemplate = ::LoadResource(hInst, hRsrc);
     ASSERT(hTemplate != NULL);
 
     pTemplate = (DLGTEMPLATE*)::LockResource(hTemplate);

     //Load coresponding DLGINIT resource
     void* lpDlgInit;
     HGLOBAL hDlgInit = NULL;

     HRSRC hsDlgInit = ::FindResource(hInst, MAKEINTRESOURCE(IDD_INDIRECT),
                             RT_DLGINIT);
     if (hsDlgInit != NULL)
     {
          // load it
          hDlgInit = ::LoadResource(hInst, hsDlgInit);
          ASSERT(hDlgInit != NULL);

          // lock it
          lpDlgInit = ::LockResource(hDlgInit);
          ASSERT(lpDlgInit != NULL);
     }

     //ToDo: Modify DLGTEMPLATE in memory if desired

     CDialog dlg;
     dlg.InitModalIndirect(pTemplate, NULL, lpDlgInit);  
     dlg.DoModal();    
 
     ::UnlockResource(hTemplate);
     ::FreeResource(hTemplate);
     if (hDlgInit)
     {
          ::UnlockResource(hDlgInit);  
          ::FreeResource(hDlgInit);
     }    
}
