Found out how to make it work:

Use this in your Button_Click on Form2:

FormCollection fc = Application.OpenForms;

Form1 fg = (Form1)fc["Form1"];

Control.ControlCollection cc = fg.Controls;

TextBox t1 = (TextBox)cc["textBox1"];

t1.Text = "something";

I know why it isn't working but don't know how to get it to work.

The reason it is not working is because you create 2 Form1's. The Program.cs file is creating 1 and you are creating 1 too. The Form1 you see on the screen is not the Form1 you are creating int the class C11 but the one created by default in Program.cs. Somehow you need access to the Form1 created in the statement:

Application.Run(new Form1());

try making form1 as a child of form2 so it can access his controls properties, may not be it but trying never hurts.
