Hi,

how is it possible to load themes from an external dll?


CXTPOffice2007Images::CXTPOffice2007Images()
{
    m_mapImages.InitHashTable(XTP_OFFICE2007_IMAGES_HASH_TABLE_SIZE, FALSE);

    m_bFreeOnRelease = FALSE;
    m_hResource = 0;
    m_lpTextFile = 0;
    m_lpTextFileEnd = 0;
    m_pConnection = NULL;

    SetHandle(AfxGetInstanceHandle());

    m_pLayerBits = NULL;
    m_hbmLayer = CXTPImageManager::Create32BPPDIBSection(NULL, 512, 512, (LPBYTE*)&m_pLayerBits);

    HDC hdcScreen = ::GetDC(HWND_DESKTOP);
    m_dc.Attach(::CreateCompatibleDC(hdcScreen));
    ReleaseDC(HWND_DESKTOP, hdcScreen);

    ::InitializeCriticalSection(&m_cs);
}

This code expects the theme resources in the executable.

My resolution was after selecting theme:


    HMODULE hModule = LoadLibrary( _T("xyz.dll") );
    ASSERT( hModule );
    if (!hModule)
        return false;

    CXTPPaintManager* pPaintManager = XTPPaintManager();
    if (pPaintManager &&
        pPaintManager->GetCurrentTheme() == xtpThemeOffice2007 ||
        pPaintManager->GetCurrentTheme() == xtpThemeRibbon)
    {
        CXTPOffice2007Theme& pOffice2007PaintManager = *static_cast<CXTPOffice2007Theme*>(pPaintManager);
        pOffice2007PaintManager.SetImageHandle( hModule, style.GetResourceName() );
     }
     FreeLibrary( hModule );

This seems to work. But with current release, this runs into the warning:


void CXTPOffice2007Images::AssertValid()
{
    if (IsValid())
        return;

    XT_ERROR_MSG(
        "Error Locating Office2007 Resources.\n\n"
        "Make sure you have included the resources to your project's .rc2 file. For example to provide\n"
        "support for Office 2007 Black Visual Style by adding the following line to your project .rc2 file:\n\n"
        "#include <Styles/Office2007Black/Office2007Black.rc> to your project .rc2 file.\n\n"
        "Giving you access to the Office 2007 resources.");
}

Temporarly I documented out this code, but is there a better way to resolve this problem?

Thanks

Hi,

Guess problem in FreeLibrary( hModule ); you call.

What do you mean?
Should I free library at shut down? I thought the resources will be load into memory?

It would be nice to set an resource handle before first time the resources will be loaded.

Try making hModule a member variable and free it in your dtor, for example:

.h file:

private:
    HMODULE m_hModule;

.cpp file:


CFoo::CFoo()
{
    m_hModule = ::LoadLibrary( _T("xyz.dll") );
    ASSERT(m_hModule != NULL);
}
~CFoo::CFoo()
{
    if (m_hModule)
        ::FreeLibrary(m_hModule);
}
BOOL CFoo::SelectTheme()
{
    if (m_hModule)
    {
        CXTPPaintManager* pPaintManager = XTPPaintManager();
        if (pPaintManager &&
            pPaintManager->GetCurrentTheme() == xtpThemeOffice2007 ||
            pPaintManager->GetCurrentTheme() == xtpThemeRibbon)
        {
            CXTPOffice2007Theme& pOffice2007PaintManager = *static_cast<CXTPOffice2007Theme*>(pPaintManager);
            pOffice2007PaintManager.SetImageHandle(m_hModule, style.GetResourceName() );
            return TRUE;
        }
    }
 
    return FALSE;
}

Sorry, but I can't solve the same problem. Please help!

I use next code:

hResource = LoadLibrary(sPath);
if(hResource)
AfxSetResourceHandle(hResource);

After, on my MainFrame called:

XTPPaintManager()->SetTheme(xtpThemeRibbon);

And this call brings me to the same crash in Codejock.
