Thank you so much.Is there not a way of wrting a code to do that?

You can use an insert statement

That is usually how I insert into SQL. The CSV data can be split using the string.split method and if you parametrize the queries you will avoid SQL injection but still be susceptible to spammers so you will need to HTML encode any input.

It is fairly difficult concept described in the "Beginning ASP.NET 3.5: In C# and VB" book published by Wrox in Chapters:5, 9, 11, and 12.

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.

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.

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.

Adding dates

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.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
