Thanks for the quick replies. I created a simple application to test your comments, and it proves you are right.
I get the run time error when I want the modal form to be a child in an MDI application, and I misinterpreted the error message.

Problem solved, thanks again.

XMLwriter error

I have a large xml document and I am extracting out individual nodes from it. I don't want any manipulation.

its like
start-large
start-small
.
.
close-small
start-small
.
.
close-small
and so on.

It works fine if I do.
XmlDocument xmlDoc= new XmlDocument();
xmlDoc.Load(xr.ReadSubtree());
xmlDoc.Save("c:\\one.xml");

But for the following the XMl document I get it messed up.
XmlTextWriter xw = new XmlTextWriter("C:\\two.xml", null);
xw.WriteNode(xr.ReadSubtree(), true);

I get errors like "end element missing" or "not properly closed".

What am I doing wrong in case of text writer? xr is the xmltextReader which is reading the large file.

Your help is appreciated.

If you google using serial instead of seail, you will find many results.

You can read it easily using WMI.
Try this

using System.Management
Public string GetHDDSerialNumber(string drive)
{
    //check to see if the user provided a drive letter
    //if not default it to "C"
    if (drive == "" || drive == null)
    {
        drive = "C";
    }
    //create our ManagementObject, passing it the drive letter to the
    //DevideID using WQL
    ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive +":\"");
    //bind our management object
    disk.Get();
    //return the serial number
    return disk["VolumeSerialNumber"].ToString();
}

Source : Use WMI to get HDD's serial number
Note : You have to add System.Management.Dll from Reference

For Exploring WMI : Please Download WMI Code Creator

I think he wants the disk's hardware serial number ("SerialNumber") and not the volume id ("VolumeSerialNumber").

Any reason you specifically want to do it in C#? SSIS is probably more suited for what you're looking to do.

System.Collections.ArrayList al = new ArrayList();

Then for every element you want to add just use the a1.Add method.

As HArold said, only if forced to use 1.1. The problem with an ArrayList is it requires every object to be converted to and from object (boxing/unboxing). A List<T> gives the same functionality, but without that overhead and inconvenience!

Calculate Accounting Period from Date

drodgers28-Jul-09 4:51

28-Jul-09 4:51

Hi Guys,

Hope someone can help with this little problem I have because its driving me mad.

I need to calculate the period in which a date falls

so lets say a companies financial years starts on 1st Jan then
Jan = P1, Feb = P2 etc etc

That makes finding the period quite easy, i just take the month of the transaction.

The problem I'm having is when the FY starts on say 1st April 2009 then
Apr = P1, May = P2 etc etc

So .
15/06/2009 returns P3/2009
01/08/2009 returns P5/2009
but
15/01/2009 returns P10/2008

So far I'm using this

'Holds the date which financial year starts
Dim FYstart As Date = = CDate("01/04/2000")

'Move FYStart to current year
FYstart = DateValue(FYstart.Day & "/" & FYstart.Month & "/" & TranDate.Year)

'Months difference between transaction date and FYstart
Dim MonthDiff As Integer = -DateDiff(DateInterval.Month, TranDate, FYstart)
'Years different between the 2 dates
Dim YearDiff As Integer = Math.Truncate(MonthDiff / 12)

'Period number
Dim p As Integer

If MonthDiff <= 0 Then
    p = 12 + (MonthDiff)
Else
    p = MonthDiff

End If


Period = p
Year = TranDate.Year + YearAdj

Anyone have any pointers because everytime I think I've cracked it, I try a different FY Start / Tran Date combination and it gives me wrong answer Frown | :(

thanks in advance,
Daniel
