hey.
thanks for answering;
what i want to do is create roughly an exact replica of:
http://www.newsnow.co.uk/newsfeed/?name=Tottenham+Hotspur
the website would feature tottenham hotspur as its keywords and search sites like skysports.com and soccernet.com etc.
if you take a look at that site do you think you could tell the method that newsnow employ because i've contacted them and can't get no help.
thank you for your time

hi Paul,
I don't know how they do it I even do not understand why they don't redirect me to another site directly, they use cgi script instead... so they may do some computing or something before they redirect me.  They claim to search about 20000 sites every 5 minutes... so they must be searching like 60sites/second. Quite fast for spidering... Some sites use RSS, some don't... so they don't check (only) RSS feeds... It takes some time for Google to find new pages, so they don't use "google hack"... They really must search all 20k sites with spider. I can't tell you how they do it so fast... I doubt you will be able to search in 60sites/second with ordinary HW/i-net connection 
If you plan to support only sites with RSS feeds in your app, it should be done by checking all feeds in list. Everytime there is new feed, you can index it (write into db words and links where these words occur). When user type in a keyword, you search ur database for this keyword and u will have list of links pointing to text containing the keyword. That should be fast enought, bt I never tried something like this. It's quite interesting application, so plz let me know after u will solve this problem 
hope I helped a little,
David

Hi,
This is what i would like to happen!
1.
I have a web service and a consuming web application.
From within the web app i want to record the round trip time from invoking to getting the data returned. What is the best way to do this? Is there a class i can use?
2.
when VS creates the XML file from my request and then the responce, i want to be able to save the XML file so i can see what size it is? and is there anyway to save the data in binary form to see the difference in size?
All this is coming from part of my uni thesis!
I want to analyse the cost of using XML and web services compared to having common functionality built into every application!
I realise this is a lot to ask but any comments, suggestions, CODE is greatly appreciated.
Thanks
Colin

On the client side within the web service proxy class you can override the WebRequest() method to get the returned data size. No need to save the contents to disk.
1) Before the client invokes, save the time.
2) In public override WebRequest(..) save the data size (on request and response)
3) When the invoke returns save the time and calc the differences.
Good Luck.

Thanks
where can override this method?
i have the web service as a web reference (visual studio) within my client
thanks again for your help
Colin
|
|
|
|
|
One approach:
Right-click on the reference to the web service.
View in Object Browser
Browse to the class object for the web service.
Right-click Go To Definition
type:
protected override System.Net.WebResponse GetWebResponse(System.Net.WebRequest request)<br />
{<br />
return base.GetWebResponse (request);<br />
}
Just remember, if you "Update Web Reference" any code you've created will be overwritten.

Thanks John, im learning a lot here!
as im overriding this method do i have to explicitly call it, or would i have to do this anyway?
For my problem where/how do i call this and what type do i save the return as?
Thanks
Colin

Colin,
Here's the basic override code. I write a static function called Logger() to write the info to a textbox; you'd want to probably write to a text file or database. For some reason the response length is -1 if you get it off the object itself. You can get the response length if you read the entire stream like I've done. This is all BEFORE deserialization so you're timing will be off a bit.
You don't have to explicitly call anything. These are base methods you're overriding and the proxy is taking care of calling them for you.
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
PersonClient.Form1.Logger("startTime=" + System.DateTime.Now);
return base.GetWebRequest (uri);
}
protected override System.Net.WebResponse GetWebResponse(System.Net.WebRequest request)
{
System.IO.StreamReader sr = new System.IO.StreamReader(request.GetResponse().GetResponseStream());
string buffer = sr.ReadToEnd();
sr.Close();
PersonClient.Form1.Logger("ReqLen=" + request.ContentLength);
//request.GetResponse().GetResponseStream().Length;
PersonClient.Form1.Logger("ResLen=" + buffer.Length );
PersonClient.Form1.Logger("endTime=" + System.DateTime.Now);
return base.GetWebResponse (request);
}

thanks John ill give it a try

John
I created a public Void Logger(string strIn)
which saves the string to a database
How can i get access to this from the GetWebResponse method?
I tried WebForm1.Logger("Length" + request.ContentLength)
but i get an error
would it be possible to e-mail your sample application to me?

Thanks a lot

Hi,
i'm a .NET newbie and hope someone can help me. I try to build something like an applet (Java) with C# and .NET. I've been told this can be done by a windows forms control assembly embedded in a html page via the well known <object> tag. Indeed, everything works fine except the control's database access to a local database. Here i get the exception "SQLClientPermission denied". I'm sure the problem lies in the CLR access policies for the code of the embedded control (coming from the intranet zone). Can anyone tell me how to grant this SQLClientPermission to the code of my control?
Thanks for your help,
Fridtjof

This is what I do to prevent duplicates on my site (non-cart oriented)
1) Create a field in the table that stores a unique id with each submitted item. Create a unique index on the field.
2) Generate a unique id (if you're using php, generate an md5 digest, and use the first 10 or so chars) when the form is displayed, and store its value in a hidden input field in the form
3) When the form is submitted, add the unique id to the table along with the rest of the data. If the user goes back and hits submit again or hits refresh, reinserting the unique id will bring up a duplicate key error, which you can interpret as "you've already submitted your data".
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

I think ur basic purpose is that user should not be able to submit twice.
Now if that is the case then in the db table with which the forms fields are concerend(In which submit button is) u can have a field status which can have two values(Yes, No).When form is submitted then status value should be Yes otherwise No.
On every submission u can check the value of status by a query.If it is Yes then U can show an error msg otherwise can accept the values.
I hope this will serve ur purpose.

NO.
You can access the varibales of the other form using javascript but action will take your page to only one url.
Code below:
Here u will be redirted to test1.html
|
|
|
|
|
So, you mean each HTML page can have one or more forms, but more than one form can not be submitted at one time, right?
Thank you, man!

Hi,
i want to embed a signed windows forms control (assembly with strong name, using a .snk key pair) into a html page. Using the normal <object>-tag works fine with the unsigned control, but doesn't work with the signed one! The signed control doesn't even open! In both cases i used the same html code. Is there information missing (e.g. about the key pair)?
Thanks a lot for your help!

Hi,
here some additional informations:
1. I used sn -k key.snk for generating the key pair.
2. Then I used an attribute in the AssembyInfo.cs file to sign the control:
[assembly: AssemblyKeyFile("key.snk")]
3. In the html page the code
<object id="A" classid="http:ALib.dll#ALib.MyACtl"
width="568" height="416">
</object>
worked fine with the unsigned control. I used exactly the same code with the encrypted control. It seems to me that Internet Explorer cannot find the class "ALib.MyACtl" any more. Maybe since it is encrypted now???
Thanks for any advice,
Fridtjof
