Extract an icon from an imagelist

[Udi]

Hi,
I have an imagelist initialized in design time with
several icons files (.ico).
However, when I need to extract an icon (Image)
from the Imagelist, I can't convert it back to an icon:

statusBarPanel1 .Icon = imageList1.Imag es[0]; // cast/as don't work
// Cannot convert type 'System.Drawing .Image' to 'System.Drawing .Icon'

What am I mising here?
Thanks!
Udi.

Udi,

Unfortunately getting an icon from an image list is a function that is
not exposed in the managed class. However, you can get the icon yourself,
by calling the ImageList_GetIc on function through the P/Invoke layer. You
can pass the handle of the imagelist (exposed by the HandleProperty) to the
function and it will return a handle, which you can then pass to the static
FromHandle property on the Icon class.

Hope this helps.

this.statusBar1 .Panels[0].Icon =
Icon.FromHandle (((Bitmap)image List1.Images[0]).GetHicon());

Thanks Nicholas,
But in which dll resides ImageList_GetIc on() ?
do you have any example of it?
Thanks again!

Udi,

You will need to use the P/Invoke layer to make the call. You have to
declare the function like this:

[DllImport("comc tl32.dll", CharSet=CharSet .Auto)]
static extern IntPtr ImageList_GetIc on(IntPtr himl, int i,
[MarshalAs(Unman agedType.U4)] int flags);

Yup, Chris, for me as well!
Thanks you all!
