I'm using a pager and want to include a query string in some cases, like search to have a search parameter in the query string. Everything works fine with the pager. So, I tried the following line of code in my controller action for including search:

ASP.NET 3.5, IIS7,In my Global.asax's Application_BeginRequest, I need to extract from the request's URL an entirely seperate URL that's been embedded in it without using query string.
The solution I came up with was to hex-encode the entire target URL as if it were a directory, as follows:
http://localhost/687474703A...etc...732E6D7033/irrelevantFilename.txt
This fails for IIS7, whose ASP.NET implementation won't tolerate a URL path greater than 260 characters.My code controls how the request URL gets generated, and how it might embed the target URL in there, but it doesn't have any control over that target URL value (they're third-party URLs).How better could I embed this target URL in my request URL?
I have an access MDB database of latitude and longitude coordinates (x,y). I also have a function in VB similar to:
Public Function Distance (x1,y1,x2,y2) as Double
'Some code here
Distance = 'distance between x1,y1 and x2,y2
End Function
What I want to do is create a query that will show all locations contained in the table that are within 10 miles of user unetered coordinates (where LAT and LON are columns in the table and VarX and VarY are user proivided: SELECT *, Distance([LAT],[LON],VarX,VarY) as Dist FROM TableName WHERE Dist < 10
Obviously this doesn't work but I want to know how to accomplish this end result. Basically, I want to return a query of all locations within 10 miles of VarX and VarY. How do I incororate the Distance function into my query?
If it's not possible, what is the best workaround to accomplish this?
Using ASP.NET Visual Basic and a MS Access MDB
I have the following LINQ query inside my models/article class, but i am facing problem in add the current user id in the where statment, as i need to only display the artciles created by the login user, i tried using ; embership.GetUser().ProviderUserKey & ToInt32(Membership.GetUser().ProviderUserKey) , but all failed, either becuase the error indicates that i can not inheret the Memebership class , or because i can not convert object to integer:-
return from userarticle in db.Articles
// where userarticle.User_ID = ToInt32(Membership.GetUser().ProviderUserKey)
orderby userarticle.create_date
select userarticle;
so how i can do so , in other words what should i write after the where "userarticle.User_ID =" ?????? . Hint i am using the default login mechanisim provided by the MVC.
I have an application that I am developing using ASP.Net with visual basic code. I have a table called "Customers" that contains 3 fields. The name of each field is "Name", "LocationA", and "LocationB". I want to code a select query that list two columns. The first column should contain the field "Name". I want the second column to contain the value in the field "LocationB" if "LocationB" is not null, else I want the second column to contain the value in the field "LocationA".
View 4 RepliesTrying to use a dropdownlist to query a database so that it will return all values except 1 (or more in future versions).
For example, assume you had a simple table name "MYFRIENDS" which has two fields named "GROUP" and "NAME" with the following records:
Group
Name
A
John
B
Jane
C
Tony
D
Sue
What I want to do is create a DropDownList that has only 2 list items related to the "GROUP" field. The first list item should return records from the database related to Group A only. Then, the second list item should return all other records EXCLUDING those belonging to Group A.
The drop down list should look something like this (I've put a question mark where I don't know what to do):
[Code]....
After the selection is chosen in the above drop down list, it should query the database and return the desired result. I'm using an AccessDataSource with select parameters. Here's a sample of what that looks like:
[Code]....
Things I've tried that didn't work:
I tried using "Not A" as the the 2nd list item's value. I was thinking p1 would be replaced with the value "Not A" and the query would read "WHERE GROUP LIKE Not A". But, the query syntax "Like Not" is technically wrong. I tried changing the Where Clause to "WHERE GROUP p1" and then replaced the list item's value to "LIKE A" and the second to "NOT LIKE A". Again, I was thinking p1 would be replaced to read "WHERE GROUP LIKE A" and "WHERE GROUP NOT LIKE A". I also tried changing the "SelectCommand" itself so that after the dropdownlist changed, it would first change the selectcommand first and then run the query.
Why the first 2 items didn't work became somewhat obvious to me after thinking about it for a little while. However, I would think the 3rd one would/should work... as long as you have the sequence of events correct which up to this point I haven't been able to figure out.
I have a list view that does something like this in the ItemTemplate:
<div><%# Eval("QualificationDescription") %></div>
My problem is that QualificationDescription has line breaks in it, if I put it in a TextBox it will display them but if I put it in a div it does not. Is there anyway to get the line breaks to show in a div?

I added the iis tag because I am guessing it also depends on what server technology you use?
I'm using Entity Framework 4 for a simple app and would like to bake my connection credentials into the following connection string:
<connectionStrings>
<add name="MyEntities"
connectionString="metadata=res://*/MyDataModel.csdl|res://*/MyDataModel.ssdl|res://*/MyDataModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=localhostDEV;Initial Catalog=MyDB;UserId=myUser;Password=jack&jill;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient" />
</connectionStrings>
However, the password (which I cannot change) contains an ampersand. ASP.NET throws:
Configuration Error: An error occurred while parsing EntityName. Line XX, position YYY.
If I replace the ampersand in the password with &, I get a SqlException: Login failed for user 'myUser'. Usually this trick works, but I'm guessing that something is failing because this is technically a connection string inside a connection string.
What should I do here? Most of my classes include code like:
using (var context = new MyEntities()) {
// do work
}
Update: It turns out that the credentials I am using are a domain account, so what I really need is Integrated Security=True in the connection string rather than a password.
Encoding the ampersand as indicated in the accepted answer should work fine, though I haven't tested it.

Is It Possible to send a string consists of (,.&') in a query string ?
View 7 RepliesI have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."

I have just started with ASP.NET.
I like the idea of using Include files so that I can create various versions of individual parts of a site and decide in code which to display. I used:
<%Response.WriteFile("contentcontent.aspx")%>
to include a content.aspx file within my default.aspx page.
I would like to include a Left.aspx, Main.aspx and Right.aspx file inside the content.aspx file. I tried using the reponse.writefile function but noticed when I debug the website that the text "reponse.writefile..." displays instead of the code contained within the referenced file(s).
Can this not be done?

View 2 RepliesSo the case is this:
The user can provide a group of strings for a propert. ex:
DaysNeeded ="Sunday,Tuesday,Friday,Saturday";
In the actual UI, the days of the week are available as check boxes. I'm trying to provide a way so that the user can also set the days needed in the code behind through a property.
Now my query is, which strategy is the best way to execute certain pieces of code that are respective to the days that the user have provided. Meaning, the DaysNeeded property has sunday,Tuesday, Friday and Saturday. Each day has certain piece of code to be executed. If i have to have a forloop with a switch case for each day of the week, i feel it would cost more as i have to run the for loop, the number of days the user has given.
Is there a way that i can run a single code that matches all the set of days the user has given and run the respective code pieces?
In IE 7, I can right click on my page and select properties and (usually) see the query string that was passed to that page.

I am developing a web application using the traditional Web Forms model. I have one page that loads the details of a particular destination. The url comes in the following format [URL]. I understand that this is not properly favored when it comes to search engines. what I need is something like this [URL]. How can I get this kind of functionality through web forms.
View 9 RepliesI am curious if is out-of-date to use query string for id. We have webapp running on Net 2.0. When we display detail of something (can be product) we use query string like this : [URL]We use query string for reason that user can save the link somewhere and come back any time later. I suppose that we use url rewriting soon or later but in mean time I would like to know your opinion.
