Get HICON from XTPImageManager

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

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();

Hi,

Hi,

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 Alpha
Channel.
			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
