How to make click button to change label text in other form?

How do I make it so when I click a button in Form1 (main form), it will open Form2 while also changing a label's text (Label4) as well.

My current code for the button:

Admin objFrmAdmin = new Admin();

I don't want to change the showing code for the form I just want to add it so when I clicked the button to open that form it will also change the text on the label in Form2.

You use the object heirarchy to change the label directly.

Admin objFrmAdmin = new Admin();
objFrmAdmin.lblLabelToChange.Text = "Your Test Here";  //<= this line.

If the label doesn't appear in intellisense, then you probably need to make it public. An alternative is to use the constructor, and pass the new test:

//Constructor for Admin form
public Admin(string newLabelText)
    this.lblLabelToChange.Text = newLabelText;

Call it via:

Admin objFrmAdmin = new Admin("The new text");
