I have this code to load an animated GIF from resource

HBITMAP hbm = NULL;

CBitmap bmpLogo;

BOOL bAlpha = TRUE;

UINT nImageID = 1;

hbm = CXTPImageManagerIcon::LoadBitmapFromResource(m_hResourceModule, MAKEINTRESOURCE(IDR_GIF_ROTATING_GEAR), &bAlpha);

bmpLogo.Attach(hbm);

XTPImageManager()->RemoveIcon(nImageID);

XTPImageManager()->SetIcons(bmpLogo, &nImageID, 1, CSize(0, 0), xtpImageNormal, TRUE);

In resource the image is added as a custom resource called GIF

The Image ID is set correctly in XAML, but the GIF is not displayed. I also have tried to set the CSize to 64,64 as the GIF size, but the same result.

Hello evoX,

You can explore our sample Samples\Utilities\MarkupPad, load file Markups\Smiles.xaml

I have seen the sample, from a stand alone .GIF file it works, but loading it from resource does not work :(

Yes, a resource DLL, from where I load all the other images displayed in XAML. PNG and JPG images are displayed without any problem, only the GIF files don't work from DLL.

Hello evoX,

Visual Studio doesn't support gif as image resource.
You can add gif to resources, and when application will start, unpack gif file to tmp directory and set in XAML this path.
<Image Source='file://TMP_DIR\Smiles\3.gif>

Thanks! But why not load to memory and display it in xaml? I think that this is a toolkit pro limitation, not Visual Studio, because PNG images also are custom resources and not a standard VS resource and PNGs are displayed in XAML.
