OK I put the code, code is

oWord = New Word.Application
oDoc = New Word.Document
oWord = CreateObject("Word.Application")
oWord.Visible = True
oDoc = oWord.Documents.Add
oDoc.ActiveWindow.Selection.Tables.Add(Range:=oDoc.ActiveWindow.Selection.Range, NumRows:=DataGridView1.RowCount, NumColumns:=3)
'numcolumns:= has to be customized
'Create headers
oDoc.Tables(1).Columns(1).Cells(1).Range.Text = "Име на работник"
oDoc.Tables(1).Columns(1).Cells(1).Range.Font.Bold = True
oDoc.Tables(1).Columns(1).Cells(1).Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter
oDoc.Tables(1).Columns(1).Width = 220
oDoc.Tables(1).Columns(2).Cells(1).Range.Text = "Обект"
oDoc.Tables(1).Columns(2).Cells(1).Range.Font.Bold = True
oDoc.Tables(1).Columns(2).Cells(1).Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter
oDoc.Tables(1).Columns(3).Cells(1).Range.Text = "Дата на работа"
oDoc.Tables(1).Columns(3).Cells(1).Range.Font.Bold = True
oDoc.Tables(1).Columns(3).Cells(1).Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter
oDoc.Tables(1).Columns(3).Width = 80
'etc.
Dim i As Integer
'Export data
i = 2
oDoc.Tables(1).Columns(1).Cells.Add()
For Each row In DataGridView1.Rows
oDoc.Tables(1).Columns(1).Cells(i).Range.Text = row.Cells(0).Value
oDoc.Tables(1).Columns(2).Cells(i).Range.Text = row.Cells(1).Value
oDoc.Tables(1).Columns(3).Cells(i).Range.Text = row.Cells(2).Value
'etc.
i = i + 1
Next

Hello,
I want to find the harddisk serial number,(not volume serial) using VB.net
CAn anyone guide me or give some link for help,
Any help would be appreciated.
Thank You.

Thanks For your reply,
I have found a code in VB which when run in Administrator Login works perfectly and gives me the Serial No.
But when i run the same code under normal or Limited User, The code does not give the Serial No.
I have gone through the code to find the difference, this is where i found the difference,
SmartOpen = CreateFile("\\.\PhysicalDrive" & CStr(drvNumber), _
GENERIC_READ Or GENERIC_WRITE, _
FILE_SHARE_READ Or FILE_SHARE_WRITE, _
ByVal 0&, _
OPEN_EXISTING, _
0&, _
0&)
The CreateFile function returns a value >0 in Admin Mode but in User Mode it returns -1.
Can any one please tell me what exactly is happening in the above code and what does this CreateFile Function do.
Please , it's Urgent.
Thanks in Advance,

CreateFile is a Windows API that is used to open several kinds of devices like files, folders, COM ports, pipes, mailslots etc.
It can also open a physical disk drive or volume like in the example you have posted.
The MSDN documentation for CreateFile clearly states that opening a physical disk is dangerous and will require administrative privileges.
Check the Physical Disks and Volumes section in the following link

Hi,
I discovered the same stuff a year ago when I started using Vista.
In short:
- in order to get the drive serial number you need low-level access to it, i.e. a CreateFile
- although reading some properties is all you need, Vista will not allow you to do so when not running
as administrator. (Try dropping the GENERIC_WRITE).
IMO there is no way around it, disk serial numbers are no longer available to regular users!

I'm looking for decent article/tutorial demonstrating how to use XmlTextReader to read XML into a (large) object tree. So far the articles are only showing a simple while (reader.Read()) { bla; } loop.
Anyone ever used XmlTextReader to do some serious parsing? Otherwise I'll just go with the XmlDocument thing, that seems to be a lot easier, but I'm curious if anyone has a nice real world usage pattern for XmlTextReader.

The XmlDocument thing is an object tree so why wouldn't you just use it anyway?

Well, XmlDocument is the easier choice I agree. But if one were to use XmlTextReader to do it, how would that be done typically. I'm just curious if there's a standard way of handling this. I've experimented a bit with XmlTextReader, and I can get things working, but the end result of how I do it feels a bit kludgy.

XMLDocument is using a reader internally. You can use reflector to see how reader is used inside that. I think that will help you to understand the usage.

Nah, XmlDocument builds something generic, but the idea is to parse into a type safe tree of classes. But thanks for the suggestion anyway.

Um, wouldn't that be Serialization?

Hehe, and chromed too! My main purpose is experimenting to get a feel for this XmlTextReader thing...

If its your custom xml format then you will have an xsd for it. Use xsd.exe to spit out class definitions tagged up for deserialization.

Hi Guys,
Is there any way to restrict the files browsable in the FileBrowserDialog to a specific directory or sub directory? I've got two directories i want to browse the files in.
Anything like that exist?
Regards

Ive got an object that I inherit from DataTable and the overloaded constructor shown below
When I try to deserialize it i get the error
"The constructor to deserialize an object of type 'MyLibrary.CSVImport' was not found.
[Serializable]
public class CSVImport : DataTable
public CSVImport():base()
{
}
Project is target 2.0
I must have something missing that I need to do in order to deserialize the object. Below is the code that does the testing
DataTable dt;
FileStream fs = new FileStream(s3, FileMode.Open);
CSVImport csv = new CSVImport(fs,out err);
csv.SetFirstRowAsHeader();
// test serialization
fs = new FileStream(@"C:\test.bin", FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(fs, dt);
fs.Close();
fs = null;
bf = null;
dt = null;
fs = new FileStream(@"C:\test.bin", FileMode.Open);
bf = new BinaryFormatter();
dt = (DataTable)bf.Deserialize(fs);// Boom! Does not like this..
fs.Close();

If you inherit from a class which has a non-public deserialization constructor, you will have to implement it. Like:
public class CSVImport : DataTable
public CSVImport():base()
{
}
public CSVImport(SerializationInfo info,
StreamingContext context):base(info, context)
{
}
