Dunno, depends on how the information is presented on the page. One such page I scrape for data has the data I want in a table. The code I use to get the page is:

System.Net.HttpWebRequest req = (System.Net.HttpWebRequest) System.Net.HttpWebRequest.Create ( theurl ) ;
                
req.CachePolicy = new System.Net.Cache.RequestCachePolicy ( System.Net.Cache.RequestCacheLevel.NoCacheNoStore ) ;
 
using ( System.Net.HttpWebResponse rsp = (System.Net.HttpWebResponse) req.GetResponse() )
{
    string res = ( new System.IO.StreamReader ( rsp.GetResponseStream() ) ).ReadToEnd() ;
 
    // Then I use a Regular Expression to extract what I want
    // and insert it to the database.
}

I make no claims that this technique is "good", only that it does what I want for a rather unimportant Windows Service.

Thank you very much for your response.Its much appreciated.Each of the data are in a qutation and are separated by comma.

Can you please give me a little tip on how to use the regular exression to trancate the value and assign it to the data field?

Many thanks,

Not without seeing the page.

As mentioned, the data I scrape is in a table, so the page contains:

<td width="473" class="playlist">4:08 pm - The Beatles - Can't Buy Me Love<br>4:10 pm - The Doors - Break On Through<br>4:13 pm - Meat Loaf - Paradise By the Dashboard Light<br>4:21 pm - Klaatu - Mister Manson<br>4:25 pm - Bob Seger & The Silver Bullet Band - Long Twin Silver Line<br>4:29 pm - Eagles - Those Shoes<br></td>

and I use a Regular Expression to match <td width="473" class="playlist"> the data I want <br></td>;
Then I split further on <br> and hyphen.

You will need to find such a pattern in the page you're reading.

Thanks so much for your help.

Here is the problem :

I am trying to read data from a certain URl .Every time you run the Url with Different param it gives a result like the following. For instance runinng http://data.com/data.aspx?datefrom=20090601&dateto=20090621
will give a result of a comman separated data like the following.

"john","wood","20090203"
"terry",'brown",20090209"
etc..

How will i read that and get it in to Sql Table?All i have to run is the above URL to generate the value.

Please advice.

Thank you in advance

How can I add 12 years minus 1 day to a date please?

So, for example, if the original date is 09/06/2009 (June 9th, 2009) the calculated date will give me 08/06/2021.

Did you take a look at MSDN? The DateTime class contains methods for this:

Something like this perhaps:

DateTime newDate = DateTime.Now.AddYears(12).AddDays(-1);

How to get or set the innerText of an HTMLElement at runtime using c#

svt gdwl24-Jun-09 0:57

24-Jun-09 0:57

Using c# BHO, I want to replace the innertext of an HTML Element on browser (IE6).
IHTMLElement HtmlElemen; // where HTMLElemen.innerHTML = <TD>Hello World!</TD>

obj = (object)HtmlElemen;
obj.GetType().GetProperty("innerText").GetValue();
obj.GetType().GetProperty("innerText").SetValue();

if normally HTMLElemen.innerText gives "Hello World!",
then how can I get the same thing i.e., "Hello World!" from the obj.GetType().GetProperty("innerText").GetValue();

Find the not-existing element in int arrays.

Hi all,

I've two int arrays, something like this.

{41, 3, 5, 37, 59, 4}
{3, 59, 4, 5, 37}

As you can see 41 is not in the second array. I want to find that actually in a C# code. Basically I want to find the value which is exists only in one array.

Any comments?

Thanks a lot. Smile | :)

I appreciate your help all the time...

There might be a simpler way, but try just to iterate through the two arrays with a nested for loop and se if the items in the first array exist in the second.

Which list are you using exactly? A generic List<t>? As it also implements IEnumerable you should be able to use the extension methods on them equally.

Sounds like a set operation, I'd use sets.

measure string

hi how can i measure string height without using Graphics.MeasureString()?
i've tried to use GraphicsPath and AddString() then to GetBounds() but that gives me the exact height, but i need the height like MeasureString() function.
the reason i can't use Graphics is that i need to calculate something about the string height in a function that doesn't get Graphics variable. (in the function that does have the Graphics variable i'm using 300 dpi).

You don't need to receive a Graphics object to use one in your method. What you could do is create a 1 by 1 bitmap, and then retrieve the Graphics object from that.

using (Bitmap img = new Bitmap(1,1))
{
  float resolution = 300;
  img.SetResolution(resolution, resolution);
  using (Graphics g = Graphics.FromImage(img))
  {
    // We have a graphics object that we can use now.
  }
}
