Change picture on click, back and forth?

[kekela]

Hi!
Tried searching the forums but I came up short, sorry if I'm asking the same stupid question over and over.
I got a code snippet that looks like this:

private void pictureBox1_Click(object sender, EventArgs e)
{
      pictureBox1.Image = Image.FromFile(@"IMAGEPATH\test1.jpg");
}

Since I'm a real newbie at programming I want to know how to code to make the other picture clickable aswell and when you click it it returns to the first image in the picturebox which you can click and so forth. Should I make states for the different images or how should I go about doing it?. Any help or links are appreciated!

You could use a boolean which you toggle in the pictureBox1_Click()-method and depending on it's state (true/false) you show the first or the second image.

The pictureBox1_Click()-method will also be called when you display another image in pictureBox1 because this doesn't mean you've clicked a dedicated picture but the control which can contain any picture.

I'm not sure what you mean by "other picture" when in the following statement:

I want to know how to code to make the other picture clickable aswell and when you click it it returns to the first image in the picturebox which you can click and so forth.

In the code snippet you have posted you only have 1 picture box.
I don't see any "other" picture.

Also what do you mean by "returns the first image"?
Return it where?

What is your application supposed to do?

A) Pictures are not clickable. The PictureBox control is clickable. So you can't make the other picture clickable. You will have to write some logic that checks which picture is currently being shown, and swap when the PictureBox control is clicked.

B) This is going to get you in trouble:

pictureBox1.Image = Image.FromFile(@"IMAGEPATH\test1.jpg");

If you keep loading from harddrive every time you click you are duplicating a lot of work. Why load the same thing over and over? Load your two images into variables one time at the start, then just swap.

PictureAlpha = Image.FromFile(path1);
PictureBravo = Image.FromFile(path2);
// Your click logic
PictureBox1.Image = PictureAlpha;
