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

I always thought it just stood for events like when you use i as a variable for (i)teration. (I might just be being niave though.) What it does do is pass the event arguments to the procedure. With some events like a keydown it allows you access to what key was pressed. Other events give diffrent arguments. Cheers Simeon
