I want to click a button and cause it to add two values which are already in the textfield 1 and 2 to add and show the answer in the thirdtext field...

Dim value1 As Double
		Dim value2 As Double
		Dim answer As Double

		Double.TryParse(xValueOneTextBox.Text, value1)
		Double.TryParse(xValueTwoTextBox.Text, value2)
		Double.TryParse(xAnswerTextBox.Text, answer)

		xValueOneTextBox.Text = "5"
		Convert.ToDouble(value1)

		xValueTwoTextBox.Text = "6"
		Convert.ToDouble(value2)

		Convert.ToString(answer)
		xAnswerTextBox.Text = value1 + value2

You are almost there.

		Dim value1 As Double
		Dim value2 As Double
		Dim answer As Double

				//Set the values in the Textboxe before attempting to Parse them
		xValueOneTextBox.Text = "5"
		xValueTwoTextBox.Text = "6"

		//TryParse will store the converted value into the second parameter
		Double.TryParse(xValueOneTextBox.Text, value1)
		Double.TryParse(xValueTwoTextBox.Text, value2)

		//Now add the converted values together
		answer = value1 + value2

		//Insert the answer into the textbox
		xAnswerTextBox.Text = answer.ToString()

Hope that helps.
