CSharp Basic Function help.

Hi,

I am building/programming a freeware app in CSharp, and I am dealing with graphic "Click" functions.

I am using CSharp express 2008 (microsoft), and rather than create a "click" function for each graphic, I decided to make a function to call (this may actually slow it down, but it seems much easier to handle.).

right now there are about 4 of these -

Code:

---

        private void pictureBox5_Click(object sender, EventArgs e)
        {
                        if (pictureBox5.BackgroundImage != pictureBox33.Image)
            {
                pictureBox5.BackgroundImage = pictureBox33.Image;
            }
            else
            {
                pictureBox5.BackgroundImage = pictureBox29.Image;
            }       
        }

---

What I did was write this -

Code:

---

        public void Funky(System.Drawing.Image strParam)
            {
                if (strParam != pictureBox33.Image)
                { strParam = pictureBox33.Image; }

                else
                { strParam = pictureBox29.Image; }         
            }

---

and call it like this -

Code:

---

        private void pictureBox13_Click(object sender, EventArgs e)
        {
            Funky(pictureBox13.BackgroundImage);
        }

---

What I'd like to have happen is to have the resource be changed out, but I am thinking I am identifying it wrong, or need to convert the variable. I am new to CSharp, but experienced in other languages. Any help appreciated!

Need to Invalidate the main control to force a redraw

Thank you much for the response.

Got it working great.
