Background Image Resource Name

Jay Webster

I am trying to find out if the background image in a set of pictureboxes is the same as any of my image resources. The following always returns "None" for all the pictureboxes although they all have the background image player.

foreach (Control ctrl in this.radGroupBox1.Controls)
{
ctrl.BackgroundImage = Resources.player;

if ((Image)ctrl.BackgroundImage == (Image)Resources.blank)
         Console.WriteLine("Blank");
else if ((Image)ctrl.BackgroundImage == (Image)Resources.player)
         Console.WriteLine("Player");
else
         Console.WriteLine("None");
}

Not sure why :(

When you load the image into the picturebox you can use
pictureBox1.BackgroundImage = Properties.Resources.player;
pictureBox1.Tag = ("player");

if (pictureBox1.Tag == ("player"))
{
whatever
}

The images might be the same, but the references are not. Do you understand the difference?

Yes, I am using Control.BackgroundImage.

When I use: Console.WriteLine(ctrl.BackgroundImage.Equals((Image)Resources.player));

Console states False, the images are the same though....

So you are using the Control.BackgroundImage Property, correct? Look at the Image Class; see what the Equals Method says? Go ahead; have a look now. Do you understand what that is saying and how that is relevant?
