There is property on the form, not the button.
After adding the button to the form, on the form set the AcceptButton property on the form. You also have a CancelButton property.

all can be done in form load

IButtonControl ib = (IButtonControl )button1;
this.AcceptButton = ib;

similarly others

when you need it Enter Event
handle Key Event.

the form property is perfect.

Try this...

SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;

if (saveFileDialog1.ShowDialog() == DialogResult.OK) {
    XmlTextWriter w = new XmlTextWriter(saveFileDialog1.FileName, Encoding.UTF8);
    w.WriteStartDocument(true);
    // use w to write your XML
    w.WriteEndDocument();
    w.Flush();
    w.Close();
}

Re: Flush & Close

Hi
I have one comment, unrelated to the original topic:

like so many people on this web site, you do Flush followed by Close

IMO there is no need for that, every Close has an implicit Flush in it.

The only time you must call Flush (and the reason for its existence) is when you dont Close
right now, but want to make sure the data gets pushed forwards (at least one level).

This may be useful if e.g. you are logging to a file, while another app is trying to show
the latest content of same file.

Yes. I think the only time that Flush should be used is if you need to flush out the buffer and keep the file open. Like how you mentioned with the log file...

Hi,

This is related to the formatting, not the topic, of your message.

I am preparing an article on copying code snippets from a CodeProject message board to
Visual Studio; seems there are no problems when the browser used is FireFox, Safari, ...
but often problems arise when using Internet Explorer.

One of the factors is the tags that are present inside the < PRE> </PRE> block.
In your message the lines are separated by <br> tags; most other messages have
just regular newlines.

Could you please tell me how you get that, i.e. what tools you use, and how you go
about it. Thanks in advance.

I'm not sure I understand what you mean. I don't do anything different, and I don't see a difference from other post. Can you explain further?

It is about copying code snippets FROM CodeProject messages TO Visual Studio.

Seems like most browsers have no trouble, Internet Explorer does.
So if you are not using IE6/IE7 you would not be aware of this.

IE6/IE7 often looses formatting, that is when copied the data on the clipboard, it
does not always represent line breaks and indentation well, pasting it in a
Visual Studio source window drops the newlines, and/or the indentation (space/tabs),
resulting in a complete mess.

It depends on exactly how the HTML code was built in the first place, hence
on the browser the poster is using and the tags he is adding.

Hence my questions: what tools do you use, and how do you go about it
(e.g. which tags do you use normally).

TIA

Personally, I just type of paste code into a <pre /> tag. I assume code project automatically converts all line breaks into <br> tags.

How to iterate along each and every item of a List<t>?

----
List<int> intList = new List<int>();
//fill the list
//...

foreach(int myInt in intList){
Console.WriteLine(myInt);
}
----
This enumerates over all integers in intList, storing them in the variable myInt inside the loop so that you can access it.

Note that you can't edit the list itself during this loop, so if you are trying to remove an element from the list you will get an exception thrown. The way around this is to make a separate list to store the elements that you want removed, then loop through those later and remove them from your original list OR, see below (looping backwards and removing elements)

----
//loops through intList and removes every 0 from the list
cont int BADVAL = 0;
for(int i = intList.Count - 1; i >= 0; --i){
if(intList[i] == BADVAL){
intList.RemoveAt(i); //removes the current index from the list
}
}

Hi PhilDanger,

Thanks for reply...

I have a specific problem.... I hope u will help me out

SeatEntity is a class having fields seat_id and row_id and properties SeatId and RowId. I stored the SeatId and RowId in a List<seatentity> now while iterating each and every cell of a dataGridView Control I want to iterate through each item in List<eeatentity> and comapre its values with the cells RowIndex and ColumnIndex....
Ur help will be much aapreciated

In your loop that iterates through the DataGridView, assume that you have two values RowIndex and ColumnIndex that point to the appropriate cell.

//this is inside the loop of the datagrid view...
SeatEntity gridSeat = (SeatEntity)gridView[ColumnIndex, RowIndex].Value;
//We did a few things here, we indexed into the gridView using the column and the row, this returns a DataGridViewCell.
//We then used the .Value property to get what is stored inside.  Since this returns an object, we cast it to the type that we stored in the grid (I'm assuming you're storing SeatEntitys).

//now we can loop through the list and compare the values
foreach(SeatEntity seat in seatList){
    if(seat.SeatId == gridSeat.SeatId){
         //do something
    }
}

int i = 0;
int j = 0;

foreach (DataGridViewTextBoxColumn c in dataGridView1.Columns)
{
c.HeaderText = i.ToString();
i++;
}

foreach (DataGridViewRow r in dataGridView1.Rows)
{
r.HeaderCell.Value = j.ToString();
j++;
}

SeatEntitiy seobj= new SeatEntitiy();
foreach (DataGridViewRow row in dataGridView1.Rows)
{
foreach (DataGridViewCell cell in row.Cells)
{
foreach (SeatEntitiy se in seat)
{
//SeatEntity gridSeat = (SeatEntity)cell[ColumnIndex, RowIndex].Value;

seobj.SeatId = se.SeatId.ToString();
seobj.RowId = se.RowId.ToString();
if (cell.ColumnIndex.ToString() == seobj.SeatId.Substring(14) && cell.RowIndex.ToString() == seobj.RowId.Substring(12))
{
cell.Style.BackColor = Color.Green;

}
else
