No, in other words, you plainly have no idea what you're doing and should learn some basics before wasting all our time asking questions you don't understand the answer to.

Since you couldnt help here is how you do it declare a public, static variable of type Form1 just below the Form1 class declaration. I’ve named the variable frm1 public static Form1 frm1 = null; then when you show form2 frm1 = this; this.Visible = false; Form2 frm2 = new Form2(); frm2.Show(); then from form2 you can call Form1.frm1.show(); so thanks for all your help lol
Wow - that's some nasty ass code. Can I make a few suggestions: 1 - buy a beginners book before you become more entrenched in the really bad habits that you're currently forming. Otherwise, your code will always suck as much as this code does. 2 - try to use real variable names. form1 and form2 make sense on your first day of coding, they are not workable in a real project Seriously, you come here, ask for help, complain when you get it, and then you're all proud because you found a way that frankly, belongs in the coding horrors forum.

That's one seriously bad piece of code. Why do you think yours is better than the solution I posted above? Let's see - I've been in this industry over 20 years, and have extensive experience in developing applications including using patterns to develop robust systems - and you? Well you accept default form names. Nuff said.

I'd like to think it's Most Valuable Professional, but in my case it could be Madly Vocal Pessimist.

If the award was for that, it would be much easier for me to win one. In fact I would probably have top honors. ;P

That's also pretty bad.

But look how much code yours is. His is three lines or something, so it MUST be better.....

Thanks for that - that really made me laugh, and I needed it. :laugh:
