Code

TextBox1.Text += IO.File.ReadAllText(Txt)

Why do you use += ? It's &= in this case. "+" is used for mathematical operation ...

Also, the code is pretty easy, and I think you can make it shorter by many ways. Still, it can be useful for people to learn how Open/SaveFileDialog works (I guess ?)

Code

MsgBox("I Cant!", vbInformation, "You Suck!")

I just saw it. MsgBox is an old method ported from VB6. It's better to use MessageBox.Show. (It's not very important, since Msgbox call Messagebox.Show, but still a better habit)

Please, don't start an argue just for a thing like that, that wasn't offensive ...
Just that using & is better in this case.

You should know according to computer, 5+5 = 55, unless specified as an integer.

Yeah, but when the 2 types mix and match, you can get unexpected results..

I use + over & out of habit unless I write a integer value to a string value, in which case you will need the & over +. Even so, you can just convert the integer to a string value and it solves the problem. It's just a habit, no right or wrong here.

Well, MSDN says you should always use & to concat strings..

Language Guidelines
String Data Type
To concatenate strings, use an ampersand (&).
VB:
MsgBox("hello" & vbCrLf & "goodbye")
