Hello,
I am a noob to C# and would like to know the best method of parsing HTML. Here is an example of what I will be doing a lot of.
I would like to get the following variables
strVis = Detroit
intVisScore = 4
strHome = N.Y. Yankees
intHomeScore = 3
strInning = Final
strBoxScore = http://www.usatoday.com/sports/scores106/106278/MLB725547.htm
If you have something generic w/ good documentation I should be ok w/ that  . I like learning the HOW.
Thanks!
Ryan

You can use a regular expression to parse the string.
As a lot of your example doesn't show up in the forum (as you haven't used the Ignore HTML feature), I can't really make a meaningful example from it. Here is an example from MSDN:
string text = "One car red car blue car";
string pat = @"(\w+)\s+(car)";
Regex r = new Regex(pat, RegexOptions.IgnoreCase);
Match m = r.Match(text);
int matchCount = 0;
while (m.Success)
{
Console.WriteLine("Match"+ (++matchCount));
for (int i = 1; i <= 2; i++)
{
Group g = m.Groups[i];
Console.WriteLine("Group"+i+"='" + g + "'");
CaptureCollection cc = g.Captures;
for (int j = 0; j < cc.Count; j++)
{
Capture c = cc[j];
System.Console.WriteLine("Capture"+j+"='" + c + "', Position="+c.Index);
}
}
m = m.NextMatch();
}

Could you enlighten me to the ignore HTML?
Thanks

You don't ignore the HTML, you use it to identify the information that you want.
If you have the string "...something...<table><tr><td>some info</td></tr></table>...something...", you can use the pattern "<table><tr><td>([^<]+)</td></tr></table>" to get the information.

Hi
I have I a class that inherits from TabConrol called MyControl. I have a class that inherits from TabPage called MyTabPage, as below:
(heavily simplified)
class MyTabControl:TabControl<br />
{<br />
protected override void OnKeyDown(System.Windows.Forms.KeyEventArgs ke)<br />
{<br />
(this.SelectedTab as MyTabPage).PanelContained.KDown(ke);<br />
base.OnKeyDown(ke);<br />
}<br />
}<br />
class MyTabPage : TabPage<br />
{<br />
private MyPanel panelContained;<br />
public MyPanel PanelContained{<br />
get { return panelContained; }<br />
set { panelContained = value; }<br />
}<br />
}
How can I override SelectedTab to return a MyTabPage? If I add a MyTabPage and change the panelcontained property, this is null again when I convet it back from SelectedTab.
Seeing as it inherits from TabControl is there a nice way to make it so that I can convert it back into a MyTabPage without losing the added property?

You can't change the return type or the method parameter types in an overload.

<br />
TabControl tabs = new MyTabPage();
Since tab control does not have the PanelContained property you will not beable to use it in tabs
unless its cast back up to MyTabPage. Even though the compatible TabControl contains a MyTabPage the PanelContained property will not be exposed. You will have to do this.
<br />
((MyTabPage)tabs).PanelExposed<br />

You can use DirectoryInfo and FileInfo Class and then use getfiles method of directory ojbect to get all the files inside a particular directory. You can also use to to get a particular kind of file
DirectoryInfo dir = new DirectoryInfo(@"d:\skypak\text");<br />
FileInfo[] bmpfiles = dir.GetFiles("*.txt");

To explicitly raise an event in C# you just call the event as it were a method. You first must check to see if it is null. If it were null then there are no registered methods to that event and an exception will be thrown.
if(Clicked != null)
Clicked();
Your deal with the tab page control is more difficult. If I understood you correctly you want to fire an event of a control from the outside. You will have to send it the ?WM_MOUSECLICK? event, to do that you will need to inject that event into the message queue of Windows itself. You will need to use the native Windows API to do that. There may be other ways, but I am currently unaware of them.

I have to change some of my logic based on the error returned by a code. I have to first try to do a simple insert in a table. If it throws a error then i will have to change the statement(update) and again try the insert. How can i do this. Sorry if i hv posted the question in the wrong discussion board. It may be a quesiton of c# also
|

I assume that you expect an error because the record already exists? Then do it the other way arond; first try the update and check how many records were updated. If the record didn't exist the number of records is zero, and you know that you have to make an insert instead.
If you are using MS SQL Server, you can do this in a stored procedure:
create procedure DoSomeSetting
@SomeId int,
@SomeValue somedatatype
as
update DaTable
set Something = @SomeValue
where SomeId = @SomeId
if @@rowcount = 0 begin
insert into DaTable (Something)
values (@SomeValue)
end

IIS is installed in your PC or not. I think ,System.Net.Mail.SmtpClient.Send user virtual SMTP if you not specify Explicitly .
Check Virtual SMTP under IIS is running or not.If not then run Virtual SMTP.
Then you can send mail successfully.

on mouse up event do
draging = false
on mouse move event do
if(draging )
get mouse position every time save it to point vriable
check current postion with previous one
if they are not equal
change
this.position.x-=(point.x-e.mouseposition.x);
this.position.y-=(point.y-e.mouseposition.y);
and you are done

I can't seem to figure out a way to loop over all cells in a DataGridViewColumn from within the column itself.
I have a class which extends the DataGridViewColumn class, and from within it I need to check all cell values in a way similar to:
foreach(DataGridViewCell cell in this.Cells){
// evaluate cell contents
}
Is there any property of the column I can use to achieve this? This functionality seems to be lacking from the column classes, though implemented in the row classes.
