title: F# and winform Controls Question
body: <p>I am very new to F#, and I thought I would develop a simple winform calculator to strengthen my skills with F# and .NET.  I ran into two problems which probably have very simple answers, however, I could not find any assistance from my resources.</p>
  
  <p>First, I want to be able to change my textbox type to integer, so that when I press my "add" button the event will add the integers and not concatenate them.  For example:</p>
  
  <p>btnPlus.Click.Add(fun _ -> tb1.Text &lt;- ("2") + ("2")) gives me 22 and not 4</p>
  
  <p>How do I specify integer type for a textbox or integer type for values entered into a textbox?</p>
  
  <p>My next question has to do with syntax.  I was just wondering how to add multiple commands to an event.  That is, in the above example, let say I wanted to add the two integers, plus open another form, and run a messagebox, after clicking the button.  Do I just include commas between each command, such as: btnPlus.Click.Add(fun _ -> add integers, open form, messagebox) or is there something else involved?</p>
  
  <p>I apologize for the sophomoric questions.  There are not enough resources on F# and winforms as there are on F# and output (i.e. print, cmd, etc..)</p>
  
  <p>Thank you,</p>
