Resource management

[InVermont]

When I add a bitmap to a UiList.ListItem, does it manage the bitmap after that?
So if I use uiList.SetListObjects(list) again to change the contents of base.uiList
, do I need to clean up the old list?

How about a UiStatic? If I change the image like

// myImage is a UiStatic, previously created with another image
Hashtable h = new Hashtable();
h.Add("@image", MyNewBitmapImage );
myImage = new UiStatic("myImage", h, mySkinHelper);

is the old bitmap cleaned up?
Thanks

If you add any resources to a UiList.ListItem then require Disposing, then you'd have to call Dispose() on it yourself when you know you no longer need them.

If you're finished with hte UiList, and wont be using it again, you should call uiList.Dispose();

How about a UiStatic? If I change the image like

// myImage is a UiStatic, previously created with another image
Hashtable h = new Hashtable();
h.Add("@image", MyNewBitmapImage );
myImage = new UiStatic("myImage", h, mySkinHelper);

Usually with a UiStatic to update the image you'd just do myUiStatic.Args = newHashtableArgs; and it'll redraw itself. If wanted to free the resources used by a UiStatic, like you're showing it in a popup, and that popup is about to be destroyed, then you should call myUiStatic.Dispose()

I tried
Hashtable h = new Hashtable();
h.Add("@image", MyNewBitmapImage );
myImage.Args = h;
but it didn't change the image. using
myImage = new UiStatic("myImage", h, mySkinHelper);
does cause the image to change.

will investigate further.

You might need to have a string or a date or sometyhing in the hashtable to. ie, something that causes ToString() to return a different value than previously.

Worked like a charm.
Again, thanks a lot.
