[EditorAttribute(typeof(MyFileNameEditor), typeof(UITypeEditor))]
-
i've created a contro with this property, i let the user can select an image for the control. During the design time, it works. But when i compile and try it on another pc i the image is not loaded. So what i've to do after i load the image? [EditorAttribute(typeof(MyFileNameEditor), typeof(UITypeEditor))] [Category("Image state"), Description("Mouse over image")] //[DefaultValue("")] public string MouseMovePath { get { return MouseMove_path; } set { try { MouseMove_path = value; FileStream fs = new FileStream(MouseMove_path, FileMode.Open, FileAccess.Read); move = Image.FromStream(fs); fs.Close(); this.Invalidate(); } catch { MouseMove_path = "(none)"; } } }

I don't see how this would work properly. Your Image is being loaded from a FileStream that you're immediately closing with
fs.Close(). An underlying stream has to be open for as long as the Image is in use. The next call toInvalidate()makes it try to refresh the image... but it can't, so I would expect an error thrown at that point. -- I've killed again, haven't I?
