How to write 'not greater than zero' in VB.NET

How should I write not greater than 0 in VB.NET?

psuedocode:

if 开发者_StackOverflow中文版x is not greater than 0 then
  do something
end if

---

If something is not greater than something, then it is less than or equal to it. So x <= 0.

---

if x is smaller or equal than 0 maybe?

---

if x <= 0

Would this not do for you? Simplest and easiest way of saying "Not greater than"

---

If it's not greater than 0, it's less than or equal:

If x <= 0 Then
   ...
End If

---

try this like

If Not ListBox1.SelectedIndex < 0 Then

      'do something
    Else

do some thing End If

---

Try this

  dim x as integer = -1

  If x < 0 OrElse x = 0 Then
        'Do something in here
  End If

if value of x is less than 0 or equal to 0 but not greater than 0 it will trigger the 'Do something in here

You can just change the value of the integer x from -1 to anything you want

---

dim X as decimal

if x<0  then

end if
