1.ToString("D6") will produce 000001

something like this (ToString does the job):

        For I As Integer = 1 To 99
            ListBox1.Items.Add(I.ToString("000000"))
        Next

Dim i
Dim numChars, padChar, strText
Dim list : list = ""
numChars = 6
padChar = "0"
For i = 0 to 999
      strText = i
      list = list & Right( String( numChars, padChar ) & strText, numChars ) & vbNewLine
Next
Wscript.echo list

The Wscript.echo will display the values from a vbs file on your desktop.  Change that line to output the list variable where you need it.

well i would do this to get the list:-

Dim lst = Enumerable.Range(1, 999999).[Select](Function(i) i.ToString(CultureInfo.InvariantCulture).PadLeft(6, "0"C)).ToList()

BuggyCoder... I like it.  I didn't realize there was a build in PadLeft function.  Much cleaner than mine.  Can you explain what the "ToString(CultureInfo.InvariantCulture)" is doing?

this means your string is culture insensitive, read more here:-

tested all codes in here and they're not working..


>>list = list & Right( String( numChars, padChar ) & strText, numChars ) & vbNewLine
that line gives an error using VS2010 and vb.net



>>        For I As Integer = 1 To 99
>>            ListBox1.Items.Add(I.ToString("000000"))
>>        Next
that code works but only shows 99 records which is useless



and this line
>>Dim lst = Enumerable.Range(1, 999999).[Select](Function(i) i.ToString(CultureInfo.InvariantCulture).PadLeft(6, "0"C)).ToList()

gives and error too

it works perfectly for me, are adding System.Globalization in your namespaces.
or simply do this:-

Dim lst = Enumerable.Range(1, 999999).[Select](Function(i) i.ToString().PadLeft(6, "0"C)).ToList()
