Question

What\'s the difference between or and OrElse?

if temp is dbnull.value or temp = 0

produces the error:

Answer 1

OrElse evaluate first expression then if its true it will proceed to the statement while OR evaluates two expressions before it will proceed to their statement.

Example:

Textbox1.Text= 4

Textbox2.Text= ""

Using OrElse

  If TextBox1.Text > 2 OrElse TextBox2.Text > 3 Then
      MsgBox("True")
  End If

Result is: TRUE

Using OR

 If TextBox1.Text > 2 Or TextBox2.Text > 3 Then

            MsgBox("True")
  End If

Result is: Error cannot convert string to double.
