How can I compute the date in VB.NET?
Like for example I have TextBox1 and TextBox2.
The value of TextBox1 is 01/08/03 and the value of TextBox2 is 4.
I am getting the due date result of 01/12/03 so I tried this code;

Dim DueDate As Integer
DueDate = DateValue(TextBox1.Text) + Val(TextBox2.Text)
MessageBox.Show(DueDate)

But it doesn't work. Kindly show me how to compute date.
