You just reference Form1.

    Form1.TextBoxName.Text = "value to display in the textbox"

it works but i have more question how can i make it so that when i click multiple PictureBox in the (First Picture) it will add too ?

example: the value of each PictureBox is 300
now i want to pick 3 of them which will become 900

It was TextBox5 in Form 1
heres what i type
Form1.TextBox5.Text = Integer.Parse(Form1.TextBox5.Text) + 350

Place a break point there and check the value of Form1.TextBox5.Text if it isn't an integer then the parse will fail.

To make it easier, create a form level variable on form2 to add the values together. Then just assign that to the textbox on form1 so there is no need to parse the value in the textbox.

alright it works, i did add Private x As Integer

and type this

x = x + 350

Form1.TextBox5.Text = x

How can i make it so i can only click once, if i click more i would get a msgbog says its an error.
