I want to write a generic function which return either string or Xdocument
[Code]....
In default.aspx
XDocument doc = api.CreateJob<XDocument>("xyz");
threws the exception "Invalid cast from 'System.String' to 'System.Xml.Linq.XDocument'."
How can i do this
ASP.NET 3.5 C# I am joining two tables using Linq. Table names are MapAssets and ExitPoint. In Database they are related with 'has a relationship'
I am writing a function in my BLL to return the joined table
public List<ExitPoints> GetExitPointDetailsByProjectID(int iProjectID)
{
ctx = new CoreDBDataContext();
var exitPointDetails = from ma in ctx.MapAssets
join ep in ctx.ExitPoints
on ma.MapAssetID equals ep.MapAssetID
where ma.ProjectID == iProjectID
select new
{
//would like to have data from both tables here
ctx.MapAssets,
ctx.ExitPoints
};
return exitPointDetails.ToList();
}
This obviuosly doesn't work. And I dont know what to return at all. All constraint I have for the return is to be able to be bound to a gridview. is this the correct way? Or else whats the correct way?
i try to return string value from the function i wrote for getting string value from the table for that i havecommon stored procedure
public string getdata(string str)
{
string datanew;

At debug time I would like to see what are the keys in my InitParams collection - I can't seem to be able to list them.
EDIT:As Jon suggests below, this might be a bug within the Silverlight debugger. To reproduce, just create a new Silverlight Application within Visual Studio 2010 and just edit code
{
public partial class MainPage : UserControl
{ [code]...
I have a method like:
public T Get<T>(string key)
{
}
Now say I want to return "hello" if the type is a string, and 110011 if it is type int.
how can I do that?
typeof(T) doesn't seem to work.
I ideally want to do a switch statement, and return something based on the Type of the generic (string/int/long/etc).
how would i go about returning a generic list in json format, can anyone point me to any good examples.

When 'return false' is fired, I'm assuming that the function is stopped at that point and there's no need for exit fors and things like that?
Question: I want to call a generic function, defined as:
Public Shared Function DeserializeFromXML(Of T)(Optional ByRef strFileNameAndPath As String = Nothing) As T
Now when I call it, I wanted to do it with any of the variants below:
Dim x As New XMLserialization.cConfiguration
x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of x)()
x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(GetType(x))()
x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of GetType(x))()
But it doesn't work. I find it very annoying and unreadable having to type
x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of XMLserialization.cConfiguration)()
Is there a way to call a generic function by getting the type from the instance ?
I have a generic list which contains a class called Parameter. Parameter contains 2 integers, ParamType and ParamValue. A generic list is built containing a small number of values List<Parameter> myList I have created a function which passes in 2 parameters. These are passed individually but are used to create a new Parameter within the function. The Parameter is tested against myList, and if it is found removed. In order to do this I have used the remove function, the syntax being:
myList.Remove(new Parameter(ParamType, ParamValue));
The remove isn't working and at present I'm using LINQ to do it.
I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false.
<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' />
Then in the page I add a HandleNullableBool() function inside the ASPX page.
protected static bool HandleNullableBool(object value)
{
return (value == null) ? false : (bool)value;
}
This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page?
<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />

I have an XDocument that looks similar to
<root>
<a>
<b foo="1" bar="2" />
<b foo="3" bar="4" />
<b foo="5" bar="6" />
<b foo="7" bar="8" />
<b foo="9" bar="10" />
</a>
</root>
I wish to change the attribute foo to something else, and the attribute bar to something else. How can I easily do this? My current version (below) stack overflows with large documents, and has an awful smell to it.
string dd=LoadedXDocument.ToString();
foreach (var s in AttributeReplacements)
dd = dd.Replace(s.Old+"=", s.New+"=");
I have an XML file named PageData.xml in my App_Data folder. I want to populate an XDocument with this file using XDocument.Load.
If I supply the full physical path it works, i.e.:
XDocument vXDoc = XDocument.Load("/Work/Project/Web/100413 Dev/App_Data/PageData.xml");
...where "Work" is a folder on my C: drive.
If I try a relative path like this, though, I get a DirectoryNotFoundException:
XDocument vXDoc = XDocument.Load("AppData/PageData.xml");
"Could not find a part of the path 'C:Program Files (x86)Common FilesMicrosoft SharedDevServer10.0AppDataPageData.xml'."
This is obviously wrong, but there must be an easy way to set the correct relative path?
internal static void GetUserData(int userId, out string userName,
out string userEmail, out string userPassword)

using (SqlConnection con = Util.GetConnection())
{
con.Open();
using (SqlCommand cmd = new SqlCommand("usp_UD_SelectById", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@UD_ID", SqlDbType.Int).Value = userId;
cmd.Parameters.Add("@UD_UserName", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Output;
cmd.Parameters.Add("@UD_Password", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Output;
cmd.Parameters.Add("@UD_Email", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
userName = Convert.ToString(cmd.Parameters["@UD_UserName"].Value);
userEmail = Convert.ToString(cmd.Parameters["@UD_Email"].Value);
userPassword = Convert.ToString(cmd.Parameters["@UD_Password"].Value);
}
}
}
and the call
string userEmail;
string userName;
string userPassword;
MemberHelper.GetUserData(userId, out userName, out userEmail, out userPassword);
Sometimes I need to get just one parameter from the out parameters, how can I call the function when I want to get just one:
string userPassword;
MemberHelper.GetUserData(userId,"","",out userPassword);

View 1 RepliesWithout giving away specifics: basically, I have a bunch of users adding content to my site. What happens now is ajax sends the text to a web service which does its thing, sends the info to the DB, Sends the user an e-mail, and then returns a response to the browser to do something.
What I would like to do is change that order. I want to return a response to the browser so the user is not waiting on the e-mail to send before they get their response. Basically, I'm trying to gain every milisecond I can to quicken the response, and there's no reason for the user to wait for the server to send their e-mail before it tells them that everything worked ok. If the info went to the DB, that's all the user needs to know, they'll know the e-mail sent when it shows up in their inbox. I notice this is an issue on my local machine which has no SMTP server and can actually hang the page response up for a few extra seconds because it's throwing errors trying to send something with no SMTP server.
So, I know in my function when I say
[Code]....
it WORKS, but I want to send the e-mail after the return. Is there ANY way to get this to happen?

I am looking for a c# function to return a portion of the html. Say I have pages that render html of about 60 k in length, I want to email to users showing only the first 2k and add a link to the original page.
Sure there is a Substring function with String, but it will give me a lot of unclosed html tags.
