Hi Oleg,

Have one more trouble with this.
CopyHandle does not create a HICON, if the ImageIcon is a alpha bitmap.

Now we use this.

static HICON CreateAlphaIcon(HBITMAP hBitmap, DWORD dwWidth,DWORD dwHeight){// dwWidth & Height could be extract from HBITMAP

	// Create an empty mask bitmap.	HBITMAP hMonoBitmap = CreateBitmap(dwWidth, dwHeight, 1, 1, NULL);	// Fill icon info.	ICONINFO ii;	ii.fIcon = TRUE;	ii.xHotspot = 0;	ii.yHotspot = 0;	ii.hbmMask = hMonoBitmap;	ii.hbmColor = hBitmap;	// Create the alpha icon with the alpha DIB section.	HICON hAlphaIcon = CreateIconIndirect(&ii);	// Delete mask bitmap.	DeleteObject(hMonoBitmap);	return hAlphaIcon;}class CXTPImageManagerIconHandleEx : public CXTPImageManagerIconHandle{public:	HICON CreateIcon()	{		//		if (m_hIcon == NULL)		{			// Temporären Handle (Kopie) erzeugen.			CXTPImageManagerIconHandleEx temp;			temp.CopyHandle(*this);			// Wurde die Bitmap bereits in ein Icon konvertiert?			if (temp.GetIcon() != NULL)				// Das HICON extrahieren und setzen.				m_hIcon = temp.Detach();			// Gibt es nur ein Bitmap, dann handelt es sich um  ein Bitmap mit AlphaChannel.			else if (temp.GetBitmap() != NULL)				// Konvertieren des Alpha Bitmaps in ein Icon und setzen des Handle.				m_hIcon = CreateAlphaIcon(temp.GetBitmap(), temp.GetExtent().cx, temp.GetExtent().cy);			else				_ASSERTE(FALSE && _T("Bitmap couldn't be converted into Icon"));		}		return m_hIcon;	} 
        HICON Detach()	{		HICON hIcon = m_hIcon;		m_hIcon = NULL;		return hIcon;	}};

Please can you add also the code to create a HICON from alpha bitmap.

Thanks

Hi,

Yes, now all icons locates in single GDI object.

Please copy it first when you need single icon:

CXTPImageManagerIcon* pIcon = pCommandBars->GetImageManager()->GetImage(ID_COLOR_FORE);

CXTPImageManagerIconHandle handle;

handle.CopyHandle(pIcon->GetIcon());

HICON hIcon1 = handle;

Hello,

Thanks for answer.
But this doesn't help.
My old function use this for fill a own CImageList (with ID's) with
using ImageManager to Load from toolbar (with id's).
Now i have add my own function loading toolbar id's.

But i think, it's not correct from CJ to return no ICON.
CJ can remove this function an can add a new function.
CXTPImageManagerIcon* pIcon = pCommandBars->GetImageManager()->GetImage(ID_COLOR_FORE);
HICON hIcon1 = pIcon->CreateIcon();

Later versions store icons as one single image to decrease GDI resource usage. Try something like this:

BOOL IconFromPNG(HINSTANCE hInstance, UINT nResourceID, CXTPImageManagerIconHandle &hIconHandle)
{
hIconHandle.Clear();

    BOOL bAlphaBitmap = FALSE;
    HBITMAP hBitmap = CXTPImageManagerIcon::LoadBitmapFromResource(hInstance, MAKEINTRESOURCE(nResourceID), &bAlphaBitmap);
    if (hBitmap)
    {
        if (bAlphaBitmap)
        {
            hIconHandle = hBitmap; // Will call DeleteObject;
        }
        else
        {
            CBitmap bmpIcon;
            bmpIcon.Attach(hBitmap);
            // Convert the bitmap to a transparent icon.
            HICON hIcon = CXTPTransparentBitmap(bmpIcon).ConvertToIcon();
            hIconHandle = hIcon; // Will call DestoyIcon.
        }
    }

    return !hIconHandle.IsEmpty();
}

Hello,

have some trouble after change from V11.1.3 to V14.0.0Beta.

i add a Toolbar to XTPImageManager.
than i will get a HICON, but it return NULL.

add this lines
CXTPImageManagerIcon* pIcon = pCommandBars->GetImageManager()->GetImage(ID_COLOR_FORE);
HICON hIcon1 = pIcon->GetIcon();

after
line: pCommandBars->GetImageManager()->SetIcons(IDR_TOOLBAR_COLOR);
in CommandBarControls Sample (MainFrm.cpp).

hIcon1 is NULL.

Any solution to retrieve HICON ?

Thanks
Jimmy
