We were using ProfUIS version 2.54 and have recently upgraded to the latest version 2.91.I built all the static and dll targets of 2.91 on VS2008.

I am facing 2 problems :

1. I am getting the following assert fired at line 264 and line 267 from ProfUIS291\Src\ExtPaintManager.cpp

VERIFY( m_bmpFilterApplied.LoadBMP_Resource( MAKEINTRESOURCE( IDB_EXT_BITMAP_FILTER_APPLIED ) ) ); // Line 264
VERIFY( m_bmpFilterUnApplied.LoadBMP_Resource( MAKEINTRESOURCE( IDB_EXT_BITMAP_FILTER_UNAPPLIED ) ) ); // Line 267

I debugged ProfUIS and found that the dll is not able to find the bitmap resource IDB_EXT_BITMAP_FILTER_APPLIED and IDB_EXT_BITMAP_FILTER_UNAPPLIED. But when i open up the ProfUIS291md-RDE.dll in VS2008 and check its content i can see the bitmaps with id 30590 (for IDB_EXT_BITMAP_FILTER_APPLIED) and 30591 (for IDB_EXT_BITMAP_FILTER_UNAPPLIED) present inside "Bitmap" resource folder.

Strangely if i go about defining __STATPROFUIS_WITH_DLLMFC__ in my project under Project->Properties->Resources->General->Preprocessor Definations and below code in my *.rc2 file it is able to find the resource and hence no assert.

// Add manually edited resources here...
#if ( !(defined _AFXDLL && !defined __STATPROFUIS_WITH_DLLMFC__) )
#include <Resources/Resource.rc>
#endif

I think the above should be required only from ProfUSI static libraries and not dynamic libraries as static libraries cannot have resources.

Another observation is that no assert is fired in projects that are using ProfUIS291md.dll and they are able to find the resources.

What is going wrong here?

2. A second more important problem :

We had an .ocx that was using ProfUIS254ynd.lib(ascii static library).Now we have modified the project setting of .ocx to use MBCS character set and in additon use dynamic library ProfUIS291md-RDE.dll.Please note that i have also defined _PROF_UIS_FOR_REGULAR_DLL preprocessor symbol in project settings of .ocx.

We have a popup list that is part of the ocx and when we click on it , it is firing the following asserts and eventually crashing.

Assert is fired from file ProfUIS291\Src\ExtComboBox.cpp line 2101

void CExtComboBoxBase::OnFilterPopupListClose()
{
ASSERT_VALID( this );
if( m_pPopupListWnd->GetSafeHwnd() != NULL
&& ::IsWindow( m_pPopupListWnd->m_hWnd )
&& m_pPopupListWnd->IsWindowVisible()
)

/////
/////
}

Internally ASSERT_VALID( this ) call’s below code from from C:\Program Files\Microsoft Visual Studio 9.0\VC\atlmfc\src\mfc\wincore.cpp

if(pMap)
{
ASSERT( (p = pMap->LookupPermanent(m_hWnd)) != NULL ||
(p = pMap->LookupTemporary(m_hWnd)) != NULL);
}

Please guide me whats going wrong above.

The CExt_ProfUIS_ModuleState::InitExtension() API initializes Prof-UIS as extension DLL (RDE) for MFC regular DLL module (such as ActiveX DLL). It’s not a replacement for __PROF_UIS_MANAGE_STATE. Please invoke the CExt_ProfUIS_ModuleState::InitExtension() API in the application’s class InitInstance() virtual method of your ActiveX project:

CExt_ProfUIS_ModuleState::InitExtension(
   AfxGetStaticModuleState()
);

The __PROF_UIS_MANAGE_STATE macro is a replacement for MFC’s AFX_MANAGE_STATE macro. We need __PROF_UIS_MANAGE_STATE because AFX_MANAGE_STATE not always works in RDE modules. Your ActiveX project can use either __PROF_UIS_MANAGE_STATE or AFX_MANAGE_STATE.

I tried using the following code in CExtComboBoxBase::OnHookSpyPreTranslateMessage() :-

CExt_ProfUIS_ModuleState::InitExtension( AfxGetModuleState() );

and was able to fix the problem but it introduced other bug in our app (failed to load resoucres of other dll). Please suggest.

The regular DLL initializes Prof-UIS state managing using the following line of code:

CExt_ProfUIS_ModuleState::InitExtension( AfxGetStaticModuleState() );

You can also make EXE module using the same state managing mechanism:

CExt_ProfUIS_ModuleState::InitExtension( AfxGetAppModuleState() );

The EXE module typically never needs to manage MFC state switching. But this can help to fix errors related to MFC state switching in loaded MFC regular DLLs.

1. I will get back to you with a sample application.

2. I tried the code changes that you recommended in OnHookSpyPreTranslateMessage() method but the asserts are still firing.

When i debugged in __PROF_UIS_MANAGE_STATE; macro i found that in the below code g_pExternalModuleState is always NULL and so the m_pAfxState is never initialized with new AFX_MAINTAIN_STATE2.

Refer ..\ProfUISDLL\ProfUISDLL.cpp

CExt_ProfUIS_ModuleState::CExt_ProfUIS_ModuleState()
{
    m_pAfxState = NULL;
    if( g_pExternalModuleState != NULL )
        m_pAfxState = new AFX_MAINTAIN_STATE2( g_pExternalModuleState );
}


Moreover the function CExt_ProfUIS_ModuleState::InitExtension which initializes g_pExternalModuleState is called for those dll that do not have __PROF_UIS_FOR_REGULAR_DLL defined like ProfUIS291md.dll and for these dll also it is called with NULL parameter,which means g_pExternalModuleState will always be NULL.

Refer ..\ProfUISDLL\ProfUISDLL.cpp

void CExt_ProfUIS_ModuleState::InitExtension(
    AFX_MODULE_STATE * pExternalModuleState // = NULL
    )
{
    new CDynLinkLibrary( the_ProfUIS_ExtensionModule );
    g_pExternalModuleState = pExternalModuleState;
}
For ProfUIS291md-RDE.dll , InitExtension() is never called and so g_pExternalModuleState is always NULL.

With the change you sent is our real intent is to execute m_pAfxState = new AFX_MAINTAIN_STATE2( g_pExternalModuleState ); ?

Am i missing something or do i need to do something extra?

Regards.

1) This problem requires a test project which reproduces it.

2) This issue can be fixed by updating the following method:

bool CExtComboBoxBase::OnHookSpyPreTranslateMessage(
    MSG * pMSG
    )
{
__PROF_UIS_MANAGE_STATE;
    ASSERT( pMSG != NULL );
    if(        m_hWnd != NULL
        &&    ::IsWindow( m_hWnd )
        &&    ( GetStyle() & WS_VISIBLE ) != 0
        &&    (    pMSG->hwnd == m_hWnd 
            || ::IsChild( m_hWnd, pMSG->hwnd )
            || ::GetParent( m_hWnd ) == pMSG->hwnd
            )
        )
    {
        if(        pMSG->message == WM_ACTIVATEAPP    
            ||    pMSG->message == WM_CANCELMODE

            ||    pMSG->message == WM_SIZE
            ||    pMSG->message == WM_NEXTDLGCTL
            ||    pMSG->message == WM_LBUTTONDOWN
            ||    pMSG->message == WM_RBUTTONDOWN
            ||    pMSG->message == WM_MBUTTONDOWN
            ||    CExtPopupMenuWnd::IsMenuTracking()
            ||    CExtControlBar::_DraggingGetBar() != NULL
            ||    (    (    pMSG->message == WM_WINDOWPOSCHANGING
                    ||    pMSG->message == WM_WINDOWPOSCHANGED
                    )
                    && ( ((LPWINDOWPOS)pMSG->lParam)->flags&(SWP_NOMOVE|SWP_NOSIZE) ) == 0
                )
            ||    (    ( pMSG->message == WM_ACTIVATE || pMSG->message == WM_MOUSEACTIVATE )
                &&    (! ::IsChild( m_hWnd, pMSG->hwnd ) ) 
                )
            )
        {
            OnFilterPopupListClose();
            return true;
        }
    }
    return CExtHookSpy::OnHookSpyPreTranslateMessage( pMSG );
}

Hi,

As suggested in my last post, if I replace __PROF_UIS_MANAGE_STATE with CExt_ProfUIS_ModuleState::InitExtension( AfxGetModuleState() );under the function in CExtComboBoxBase::OnHookSpyPreTranslateMessage(), it results in multiple assertion in LoadToolbar for the OCX getting loaded by the same application.

Please suggest.
