Please tell me what the "e" means!

Question

Hi everyone, Could you please tell me what the "e" means in the following line of code? Private Sub Button2_Click(ByVal sender As System.Object, ByVal **e** As System.EventArgs) Handles Button2.Click Note: I added the "*" symbol just to highlight it, and I also added spaces before and after, to make it easier to find. I have searched all through the docs and online help, but I can't figure out what this "e" stands for, or what it means, what it does . . . well, you get the picture. I did run into a ref to something called, The Constand e, or something like that, but that didn't help, and it didn't tell me why it's in this line of code, or why it shows up a lot. Your help, as always, is greatly appreciated. BeaglepackGP
