When Execute The Page, It Returns The Calling Pages Url From Request?
Mar 25, 2010
I have a dynamic catalogue, where customers select products they are interested in. The manager of the company I am doing this for would like to be able to create an up to date offline catalogue at any given time, to send out to customers who dont have an internet connection. So far its going really well. I am using Server.Execute to get the content for each page, then putting it in static html pages and changing the dynamic links to static html links (ie changing all aspx links to htm). I am able to output all the pages for about us, contact us, home, and the entire catalogue. However, one of the stylesheets which is included in the page based on the URL (if the page is in the administration section then it is not included, otherwise it is) is not being included in the pages when it should be. I have tried outputting the URL but it just returns the URL of the calling page, not the page being called.

I am wondering if there is anyway to grab the html that is generated from an ASP page.I am trying to pull a table from the page,and I foolishly used a static html page so I would not have to be constantly querying the server where this page resides while I tested out my code.The javascript code I wrote to grab to unlabeled table from the page works.Then when I put it into practice with the real page and found that the ASP page does not generate a viewable page with a jquery .get request on the URL.
Is there any way to query the page for the table I need so that the ASP page returns a valid page on request?(I am also limited to using javascript and perl for this,the server where this will reside will not run php and I have no desire to learn ASP.NET to solve this by adding to the issue of proprietary software)

I'm experiencing a really confusing error. Exactly every other time the page returns
ERROR [23000] [DataDirect][ODBC Progress OpenEdge Wire Protocol driver][OPENEDGE]Integrity constraint violation:uniqueness constraint violation (7518)and else it works nicely.
Here's the SQL:
SELECT SlsOrder.Orderdate, SlsLine.LineNum, CASE WHEN SlsLine.AllDelivered = 1 THEN 'X' ELSE '0' END AS 'AllDelivered', Item.ItemName, Item.TechName, SlsLine.IntDlvDate, SlsLine.OrderNum, SlsLine.ItemCode, SlsLine.Version, CEILING(SlsLine.Qty) AS 'Qty',
Item.QtyUnit, ROUND((SlsLine.Price*SlsLine.Qty),2) AS 'rowSum', ROUND(SlsLine.Price,2) AS 'Price', IFNULL(SysText.InfoText, '-') AS 'InfoText' FROM PUB.SlsLine INNER JOIN PUB.SlsOrder ON (SlsLine.OrderNum=SlsOrder.OrderNum) INNER JOIN PUB.Item ON (SlsLine.ItemCode=Item.ItemCode)
LEFT OUTER JOIN PUB.SysText ON (SlsLine.SlsLineKey=SysText.SysTextKey) AND SysText.NoteType = 'OrdConfRowE' AND SysText.ConsTxt = '' WHERE (SlsLine.OrderNum = '" & o & "') ORDER BY SlsLine.LineNum

I'm looking for a good way to prevent the scenario of the page calling itself repeatedly.
I have a page, that to be rendered needs to make an HTTP request to an RSS feed. If the URL to that RSS feed happens to be the current page, it will fire off a request to itself. The new request would start off another request to the page, which would start another request... This continues until the site grinds to a halt when all available connections are busy in this recursive loop.
A few notes:
The URL to the RSS is entered by the user.
This is a page in a CMS, the URL of the page could be almost anything and could change after the RSS URL is entered.
In this case, the user entered a URL to a remote server that lead to a redirect back to the page.
A few ideas:
I could just deny all requests from the localhost IP before rendering.
Before sending the request, I could track in a common location which requests are active and not even send it if it's already in the middle of another request to the same address.
Maybe add a custom user-agent to the request header and deny the request if that user agent is seen?

I have 2 master pages with same (href) links on top of the page. Now these links load on the same master page when clicked on (by requirement). The problem is both these master pages have same links, so basically the same page shall be loaded in the master page.Now what i need is when the person is on Master Page 1 and clicks on the link it should load in the same page. Whereas if the user is on Master Page 2 and clicks on the same link, i should be able to change the master page from 1 to 2 and load that in Master Page 2. Something like DirectCast.

I am using 3.5 .NET VB. In a code behind I am calling a page using this approach:HttpContext.Current.Server.Execute("Survey.aspx").On the survey.aspx page I have several textboxes are varying sizes. If I run the survey.aspx page alone, the textbox appear on the screen in the correctsizesettings. However, when I use the HttpContext.Current.Server.Execute method to execute the survery.aspx page from another page, the textboxes always come back a fixed width of like 200px or so. It doesnt matter what I change the size of the width to in the survey.aspx page, they are always rendered the same size for every textbox on the page. The changes do show up if I view the survey.aspx page alone though without calling it through another page so I know my syntax for changing the width settings is correct.Does anyone have any idea what causes this and how to resolve it? I am stumped.

I've got this application that works locally and when deployed and using a .mdf SQL Express database file (which I usually use for testing purposes). However, when I change it to work with our SQL Server 2008 the app works but the service doesn't. For example if in my code behind of a page I have a button that adds data to a table such as this it works fine:
public static string connString = @"Data Source=server1;Initial Catalog=Project;Integrated Security=True";
protected void btnAddProj_Click(object sender, EventArgs e)
{
using (var sqlc = new SqlConnection(connString))
{
sqlc.Open();
var cmd = sqlc.CreateCommand();
int intProjectID;
// Add the project info to the database
cmd.CommandText = "INSERT INTO tblProject VALUES(@ProjName,@ProjTeam,@ProjStart,@ProjEnd)";
cmd.Parameters.Add("ProjName", System.Data.SqlDbType.NVarChar).Value = txtProjName.Text;
cmd.Parameters.Add("ProjTeam", System.Data.SqlDbType.Int).Value = ddlTeamSupported.SelectedValue;
cmd.Parameters.Add("ProjStart", System.Data.SqlDbType.NVarChar).Value = txtStartDate.Text;
cmd.Parameters.Add("ProjEnd", System.Data.SqlDbType.NVarChar).Value = txtEndDate.Text;
cmd.ExecuteNonQuery();
}
}
My web.config is setup to use impersonation on that server and all works perfectly well. However, for my service the query doesn't seem to return anything and I get a 400 Bad Request error. The code for the jquery is:
$.ajax({
type: "POST",
async: false,
url: "Services/ProjectService.svc/test",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
console.log(data);
}
});
And for the Service:
[ServiceContract]
public interface IProjectService
{
[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json)]
ArrayList test();
}
public static string connString = @"Data Source=server1;Initial Catalog=Project;Integrated Security=True";
public ArrayList test()
{
var sqlc = new SqlConnection(connString);
sqlc.Open();
var cmd = sqlc.CreateCommand();
cmd.CommandText = "SELECT ProjectID FROM tblProject";
var reader = cmd.ExecuteReader();
ArrayList temparray = new ArrayList();
while (reader.Read())
{
temparray.Add(reader[0]);
}
sqlc.Close();
return temparray;
}
If instead of querying the database I have the service just return static data then it works fine. What could cause my service not to be able to connect to the database when the rest of the code behind for the app works?

I have a wcf service that randomly begins to fail when requesting the autogenerated javascript that wcf supports making. But I have no luck tracking down why. The js thing is part of the wcf featureset, so I dont know how it can suddenly begin to fail and be unable to work until IIS is recycled.
The http log gives me:
2010-06-10 09:11:49 W3SVC2095255988 myip GET /path/myservice.svc/js _=1276161113900 80 - ip browser 500 0 0
So its an error 500, and that is about the only thing I can figure out. The event log contains no information.
Requests to /path/myservice.svc works just fine. After recycling IIS it works again, and some days later it begins to fail until I recycle IIS.
<service
name="path.myservice"
behaviorConfiguration="b">
<endpoint
address=""
behaviorConfiguration="eb"
binding="webHttpBinding"
contract="path.Imyservice" />
</service>
...
<endpointBehaviors>
<behavior name="eb">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="b">
<dataContractSerializer maxItemsInObjectGraph="2147483647" />
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
I dont see any problems in the web.config settings either.
Edit:
Just to make it clear - It is the generation of javascript that fails, my code is never invoked. Calls to the service works just fine.

Here's my setup:
Simple mvc page with a few controls that includes a validation summary area.
Once the fields are completed there's a download button.
If I enter something invalid, as expected, my controller code updates the UI with the appropriate error. However, if I then correct the error, and then click the download button a file is downloaded, but the UI never gets updated - presumeably since there's no update on the view.

I have a drop down in an ASP.NET page. Whenever the value of the drop down changes an ASP.NET AJAX request is made to the server. I also attached a jQuery "change" event handler to that list to execute some code when the value is changed. So, probably two different event handlers are being attached to the same drop down, and it's causing some problems, i.e., sometimes wrong drop down values are sent to the server. I don't know why is this happening but I think attaching two different event handlers to a same drop down may be the reason.
Can anyone tell me what is the problem here? If what I guessed is true, then is there any other way to execute some custom javascript code before asp.net AJAX request is sent ?

Hoping someone can point me to a solution, haven't been able to find one yet.
I'm using the standard way for send HttpWebRequest
[Code]....
As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.

I've a question I don't know if this is possible or not. I've tried a lot of things till now but could not accomplish on what I wanted to do.
What I want to do is call a web page from another page and some how execute either the page load event or page init event and get the result of the page in the first page.
Page A calls page B. Page B has static text and a label which is being set in page load event.
Page B - Code behind
[Code]....
Page B -- HTML code
[Code]....
Till now what I've tried is using the code below from page A. But this code just returns the Html code and nothing else.

In Web Forms I would tend to do this by having one actual page. I would then use a tab container to give the appearance of several pages of a "wizard" by enabling and disabling tabs. Of course the URL wouldn't change, but otherwise it gave the impression I wanted. The values of the hidden controls were maintained in viewstate, and when the submit button on the last page was pressed I could obtain all the information I needed from the state of the controls.This obviously is not how it should be done with MVC. However, I don't really want session state or to write partially complete submissions to the database. What is the best way of handling this?

I am trying to implement the webrequest get and post methods. I am accessing a secure site that requires login authentication and was told that instead of sending a login request all the time; login to the site and capture the cookie and use this to send it in the header to get results from the page. In other words let us use google for example. Lets say google required u to login before searching for something. Now I login through my browser and leave the site logged in. Now I send a httwebrequest from my program that includes the cookie authentication details in the request header and get results for say ?param=sports. Now when I increment the page number like &page=3, I am still only getting page 1 results.
Here is some code:

Now I am using the request method GET. This is in the actual request header from the original request.

I am calling a remote service and authenticating using a certificate. When testing with a Console App, everything works fine. When calling from an ASP.NET Website (.NET 4.0, IIS7) I receive a response code of 401 -- Unauthorized.I am adding the certificate using code such as:
var client = new TheGeneratedProxy();
client.ClientCertificates.Add(new X509Certificate("D:cert.pfx", "myPassword"));
(NOTE: I have also loaded the .pfx into the local Certificate Store using IE. The certificate is loaded into my "Personal" store -- so I suspect this to be the problem, since the Website will be running under a different account.)
