Set child form image from parent form?

Question

So I am making some achievement pop ups for a lame game and so I made a custom messagebox form and I have been successful in setting the popups picturebox image with local images but I need help using embedded resources as images.

So far Ive used constructors to set the images and string but I can't use them for embedded images.

Parent Form:

MessageForm MsgFrm = new MessageForm
{
AchievementString = "L33t H4x0r - Reach 1337 score.",
PictureString = "C:\\Users\\Resources\\H4x0r_50x50.jpg"
};
MsgFrm.Show();

Child Form:

public string Achstring { get; set; }
public string Picstring { get; set; }
private void MessageForm_Load(object sender, EventArgs e)
{
achievement_lbl.Text = AchievementString;
achievement_pic.Image = Image.FromFile(PictureString);
}

Using the code above I can only use local images and my goal is to use images embedded in resources but to pass them as an arg of sorts as above.

Answer 1

You should either pass the Image object to a constructor or declare an Image property to set.

public MessageForm(Image img)
{
    InitializeComponent();
    achievement_pic.Image = img;
}

Or

Parent form

MessageForm MsgFrm = new MessageForm
{
    AchievementString = "L33t H4x0r - Reach 1337 score.",
    PictureImg = embeddedPicture
};
MsgFrm.Show();

Child form

public string Achstring { get; set; }
public Image PicImage { get; set; }

private void MessageForm_Load(object sender, EventArgs e)
{
    achievement_lbl.Text = AchievementString;
    achievement_pic.Image = PicImage
}

If you need more control in the parent form, you could make the control public or create a public property for the image.

public Control PicControl => achievement_pic;

Answer 2

Using the info Ed Plunkett gave me I was able to come up with the solution.

First you have to give the PictureBox the public modifier in it's properties then,

MessageForm MsgFrm = new MessageForm
{
AchievementString = "L33t H4x0r - Reach 1337 score.",
};
MsgFrm.achievement_pic.Image = Properties.Resources.H4x0r_50x50;
MsgFrm.Show();

Done
