is this possible?

[tayspen]

HI,

would it be possible to print only the TEXT forcast of this website into a textbox....no pictures no nothing just the text. if so how?

[campkev]

copy and paste into notepad? ;)

[tayspen]

ha ha.... come on now. i want to do it via C#. so any SERIOUS ideas?

[campkev]

I was just kidding because I'm not 100% sure what you meant. You want your program to pull data from a webpage and print it out, is that right?

Lol yea i knew you were kidding. ok this is what i want it to do. Just in the link above in earlier post as you can see there is 36 hrs worth of forcast right there in text. I want to open that info into a text box. (juast text no pics) thats as clear as i can get.Possible?

[campkev]

possible but prly not the best way to add weather to an app. i would suggest retreiveing an rss feed from a site like http://www.rssweather.com .

because to get weather from that site yo would need to sent a WebRequest for that website then parse the html for the entire page, and remove all the extra html tags. making extra work thats not needed, but i will include source on a htmlGet and htmlPost so you have an idea on how to do this anyways

this code gets the html from a site

using System.Net;


		private string GetHTML(string strURL)
		{
			WebResponse objResponse = null;
			String strHTML;

			try
			{
				Uri objUri = new Uri(strURL);
				WebRequest objRequest = WebRequest.Create(objUri);
				
				objResponse = objRequest.GetResponse();				
				Stream objStream = objResponse.GetResponseStream();;

				Encoding encode = System.Text.Encoding.UTF8;
				StreamReader objReader = new StreamReader(objStream, encode);

				strHTML = objReader.ReadToEnd();

			}
			catch(Exception ex) 
			{
				return ex.ToString();

			}
			finally 
			{	
				objResponse.Close();

			}

			return strHTML;

		}

		private string Post(string strURL, string strPostData)
		{
			WebResponse objResponse = null;
			string strResult = null;

			try
			{
				Uri objUri = new Uri(strURL);
				WebRequest objRequest = WebRequest.Create(objUri);

				objRequest.Method = "POST";
				objRequest.ContentType = "application/x-www-form-urlencoded";

				StringBuilder UrlEncoded = new StringBuilder();
				Char[] reserved = {'?', '=', '&'};
				Byte[] SomeBytes = null;

				if(strPostData != null)
				{
					int i = 0, j;
					while(i< strPostData.Length)
					{
						j = strPostData.IndexOfAny(reserved, i);
						if(j == -1)
						{
							UrlEncoded.Append(HttpUtility.UrlEncode(strPostData.Substring(i, strPostData.Length - i)));
							break;
						}
						UrlEncoded.Append(HttpUtility.UrlEncode(strPostData.Substring(i, j-i)));
						UrlEncoded.Append(HttpUtility.UrlEncode(strPostData.Substring(j, 1)));
						i = j+1;
						
					}


					SomeBytes = Encoding.UTF8.GetBytes(UrlEncoded.ToString());
					objRequest.ContentLength = SomeBytes.Length;


					Stream objStream = objRequest.GetRequestStream();

					objStream.Write(SomeBytes, 0, SomeBytes.Length);
					objStream.Close();
				}
				else
				{
					objRequest.ContentLength = 0;
				}


				objResponse = objRequest.GetResponse();

				Stream objReceiveStream = objResponse.GetResponseStream();

				Encoding encode = System.Text.Encoding.UTF8;
				StreamReader objReader = new StreamReader(objReceiveStream, encode);

				strResult = objReader.ReadToEnd();

				
				
			}
			catch(Exception ex)
			{
				return ex.ToString();
			}
			finally
			{
				if(objResponse != null)
				{
					objResponse.Close();
				}
			}
			
			return strResult;

hey thanks man. i thought rss would be the better option. but dont no how to read those. is it easy. Sample code? but thatnks for this im gonna look at it now :)

[plazmo]

i dont know yet but thats something i want to learn, so after i learn if you havent figured it out yet i will post some code. post your code when you figure it out to please

[tayspen]

will do, thanks for your help.

[plazmo]

well i know one way to use rss feed if you know how to work with datasets. its very simple, but i dont know if this is the best way to do this. if someone could suggest a better way i could try.

DataSet ds = new DataSet("RSS Feed");
			ds.ReadXml(@"http://securityfocus.com/rss/news.xml");
			dataGrid1.DataSource = ds;
			dataGrid1.DataMember = "Channel";
			dataGrid1.CaptionText = "RSS Feed";

im a bit confused on how this works...i will research rss files....

[tayspen]

perhaps this will help

i am going to take a look at it

EDIT: ising this libary and example i successfullf pulled the headline news from google.(just title)

ok.

[plazmo]

have you gotten anywhre with this, i made up a program if you want to see it

[tayspen]

sure i would love to see it. i have been able to retrive the headlines. thats about it though havnt really dug in. yea if you wouldnt mind posting it id like to see

[plazmo]

http://anti-intelligence.com/files/rssReader.zip

i made this up sorta quick so i hope you understand it

but i displayed it in both a treeview and datagrid

the only problem is googles rss displays html in part of the rss so its hard to read without removing the html

[tayspen]

Nice. Yea i understand it. I want to extend it so it gets the whole article. then can save that to a text file. Looks good thx for the ex.

EDIT: For some reson it doesnt seem to be reading google correctly.
