C# beginner Numering question

Hello,

We have a program at work wich runs on C# (I am new to this).

There is a function (seen in the code below) which numbers ID's.

When I choose 3 letters like 'AZM' the numbering works.

AZM001
AZM002
AZM003
etc...

But when I want to use numbers: 001001, 001002, 001003 it doesnt work.
I get:
001001 (this is good)
011002 (this should be 001002)
011003 (this should be 001003)

I hope that you guys can help.

Code:

---

function GetPaddedPatNo(LastID, padding)
{
  var snums = '0123456789';
  var sres = '';
  var i = 0;
  // remove all non-numerical characters
 
 for(i=0; i< LastID.length; i++)
  {
    if(snums.indexOf(LastID.substr(i,1)) >=  0)
      sres += LastID.substr(i,1);
  }

  var ires = new Number(sres);
  if((ires.NaN) || (ires == 0))
    ires = 0;

  if(ires > 9999)
    ires = ires % 10000;

 var nextPat = ires + 1;
  sres = nextPat + '';
  while(sres.length < padding)
    sres = '0' + sres;

  return(sres);
}
@INST_SHORTCODE + GetPaddedPatNo(LastPfxPatNo(@INST_SHORTCODE), 3);

Do you want to add 00 the result ?

I don't know if I understand you.

001 is the studycode.
Per study there are multiple participant which incriments by 1 001, 002, etc..

So if a student is added to the study it looks like:
001001,001002,001003,etc

This worked for me

Code:

---

function padNumber(number,length) {
    var str = '' + number;
    while (str.length < length)
        str = '0' + str;
    return str;
}
 function GetPaddedPatNo(number,pad)
  {
    var mystr=stripAlphaChars(number);
        var ires = new Number(mystr);
        var newNumber;
          if((ires.NaN) || (ires == 0))
                ires = 0;

          if(ires > 9999)
                ires = ires % 10000;

        alert(padNumber(mystr,pad));
       

  }
  function stripAlphaChars(pstrSource)
{
var m_strOut = new String(pstrSource);
    m_strOut = m_strOut.replace(/[^0-9]/g, '');

    return m_strOut;
}

call as

return GetPaddedPatNo('4', 3);

You don't need to write custom code to pad strings.

csharp Code:

var num = 1;
var str = num.ToString("000");
 
MessageBox.Show(str);

csharp Code:

var num = 1;
var str = num.ToString().PadLeft(3, '0');;
 
MessageBox.Show(str);

csharp Code:

var num1 = 1;
var num2 = 2;
var str = string.Format("{0:000}{1:000}", num1, num2);
 
MessageBox.Show(str);

I think question is in Javascript :)

Now that I look at the original code, I think maybe you're right. That leads me to ask, why is this question in the C# forum?

Why indeed...Moved

Sorry for that.
Normally I use VB, but a coworker asked me to take a look at it.

Here is how is was solved:

Code:

---

function GetPaddedPatNo(LastID, padding)
{
  var snums = '0123456789';
  var sres = '';
  var i = 0;
  // remove all non-numerical characters
 
 for(i=0; i< LastID.length; i++)
  {
    if(snums.indexOf(LastID.substr(i,1)) >=  0)
      sres += LastID.substr(i,1);
  }

  var ires = new Number(sres);
  if((ires.NaN) || (ires == 0))
    ires = 0;

  if(ires > 999)
    ires = ires % 1000;

 var nextPat = ires + 1;
  sres = nextPat + '';
  while(sres.length < padding)
    sres = '0' + sres;

  return(sres);
}
@INST_SHORTCODE + GetPaddedPatNo(LastPfxPatNo(@INST_SHORTCODE), 3);

Thank you very much for helping guys..

And see u soon at the VB.NET forums ;-)
