[RESOLVED] [2005] format question

[newpat]

why I set the format to 0000, but it doesn't work?
here is my code

Dim loud As Integer
loud = TextBox1.Text
loud = Format(loud, "0000")
console.writeln(loud)

if my textbox1 is 0123, it just show me 123...

[stanav]

Dim loud As Integer
If Integer.TryParse(TextBox1.Text, loud) Then
    Debug.WriteLine(loud.ToString("0000"))
Else
    Debug.WriteLine("Invalid number")
End If

[newpat]

so, is that right?
loud = loud.tostring("0000")

Nevermind, stanav beat me to the punch.

loud = loud.tostring("0000")

stanav gave you the solution you were asking for. Did you give it a shot?

In addition, here is some more on formatting:

Dim loud As Integer
If Integer.TryParse(TextBox1.Text, loud) Then
    Debug.WriteLine(loud.ToString("0000"))
Else
    Debug.WriteLine("Invalid number")
End If

but how can I save the 0123 to loud?
I tried, although it come out with "0123", I dun know how can I save it to loud.

Integers do not have leading zeros. Save it to a string variable if you must have the leading zero.

' loud    
        Dim loud As Integer = 123
        Dim str As String = loud.ToString("0000")
 
        MessageBox.Show(str)

No, that's not what I meant....
What you have displayed on screen is just a string representation of the integer value. And you can not format an integer itself but rather its string representation. That's why you have to to convert the integer to string and then format that string.

ok then...My integer is to compare with another integer...
However, I have found out another way to do my expection.
Thx for all!
