In the MFC project environment, make ActiveX OCX to cancel the security prompt of IE browser

Add # pragma once in the next line of the xxxctrl. H (XXX is the project name) header file

// ------- Add ---------------
// Cancel IE Security Prompt
# Include "objsafe. H"
// --------- Add ----------------------------

And declare part of the declaration in the header file class (same as the cxxxctrl () constructor)

// ---------- Added the Security Prompt for canceling ie ----- = ---- declare_interface_map () begin_interface_part (objsafe, IObjectSafety) stdmethod _ (hresult, break) (/* [in] */refiid riid, /* [out] */DWORD _ rpc_far * pdwsupportedoptions,/* [out] */DWORD _ rpc_far * pdwenabledoptions); stdmethod _ (hresult, setinterfacesafetyoptions) (/* [in] */refiid riid,/* [in] */DWORD dwoptionsetmask,/* [in] */DWORD dwenabledoptions); end_interface_part (objsafe ); // --------- add ----------------------------

Implementation file in CPP

After the bool cmax200ctrl: cmax200ctrlfactory: updateregistry (bool bregister) function, add the following

Note that the following code should replace cmax200ctrl with your own class name.

Implement the createcomponentcategory and registerclsidincategory helper functions by adding the following cathelp. h and cathelp. cpp files to your project.

1. Cathelp. h

         #include "comcat.h"      // Helper function to create a component category and associated      // description      HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription);      // Helper function to register a CLSID as belonging to a component      // category      HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid);

   Cathelp. cpp

         #include "comcat.h"      // Helper function to create a component category and associated      // description      HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription)      {         ICatRegister* pcr = NULL ;         HRESULT hr = S_OK ;         hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,                               NULL,                               CLSCTX_INPROC_SERVER,                               IID_ICatRegister,                               (void**)&pcr);         if (FAILED(hr))            return hr;         // Make sure the HKCR\Component Categories\{..catid...}         // key is registered         CATEGORYINFO catinfo;         catinfo.catid = catid;         catinfo.lcid = 0x0409 ; // english         // Make sure the provided description is not too long.         // Only copy the first 127 characters if it is         int len = wcslen(catDescription);         if (len>127)            len = 127;         wcsncpy(catinfo.szDescription, catDescription, len);         // Make sure the description is null terminated         catinfo.szDescription[len] = '\0';         hr = pcr->RegisterCategories(1, &catinfo);         pcr->Release();         return hr;      }      // Helper function to register a CLSID as belonging to a component      // category      HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid)      {         // Register your component categories information.         ICatRegister* pcr = NULL ;         HRESULT hr = S_OK ;         hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,                               NULL,                               CLSCTX_INPROC_SERVER,                               IID_ICatRegister,                               (void**)&pcr);         if (SUCCEEDED(hr))         {            // Register this category as being "implemented" by            // the class.            CATID rgcatid[1] ;            rgcatid[0] = catid;            hr = pcr->RegisterClassImplCategories(clsid, 1, rgcatid);         }         if (pcr != NULL)            pcr->Release();         return hr;      }

2. Modify the dllregisterserver to mark the control as safe. locate the implementation of dllregisterserver in. CPP file in your project. you will need to add several things to this. CPP file. include the file that implements createcomponentcategory and
   Registerclsidincategory:

         #include "CatHelp.h"

   Define the guid associated with the safety component categories:

         const CATID CATID_SafeForScripting     =      {0x7dd95801,0x9882,0x11cf,{0x9f,0xa9,0x00,0xaa,0x00,0x6c,0x42,0xc4}};      const CATID CATID_SafeForInitializing  =      {0x7dd95802,0x9882,0x11cf,{0x9f,0xa9,0x00,0xaa,0x00,0x6c,0x42,0xc4}};

   Define the guid associated with your control. For simplicity, you can borrow the guid fromImplement_olecreate_exMacro in the main. cpp file for the control. Adjust the format slightly
   So that it looks like the following:

         const GUID CDECL BASED_CODE _ctlid =      { 0x43bd9e45, 0x328f, 0x11d0,              { 0xa6, 0xb9, 0x0, 0xaa, 0x0, 0xa7, 0xf, 0xc2 } };

   To mark your control as both safe for scripting and initialization, modify the dllregisterserver function as follows:

         STDAPI DllRegisterServer(void)      {          AFX_MANAGE_STATE(_afxModuleAddrThis);          if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))              return ResultFromScode(SELFREG_E_TYPELIB);          if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))              return ResultFromScode(SELFREG_E_CLASS);          if (FAILED( CreateComponentCategory(                  CATID_SafeForScripting,                  L"Controls that are safely scriptable") ))                return ResultFromScode(SELFREG_E_CLASS);          if (FAILED( CreateComponentCategory(                  CATID_SafeForInitializing,                  L"Controls safely initializable from persistent data") ))                return ResultFromScode(SELFREG_E_CLASS);          if (FAILED( RegisterCLSIDInCategory(                  _ctlid, CATID_SafeForScripting) ))                return ResultFromScode(SELFREG_E_CLASS);          if (FAILED( RegisterCLSIDInCategory(                  _ctlid, CATID_SafeForInitializing) ))                return ResultFromScode(SELFREG_E_CLASS);          return NOERROR;      }

You wocould not normally modify the dllunregisterserver function for these two reasons:

• You wocould not want to remove a component category because other controls may be using it.
• Although there is an unregisterclsidincategory function defined, by default dllunregisterserver removes the control's entry from the Registry entirely. therefore, removing the category from the control's registration is of little use. ========================================================== ========
