Iterator Not Iterating / Iterator Within The While Loop Returns False For The MoveNext Method?
Mar 16, 2011
I'm having trouble with something that is (or should be) fairly straight-forward.
I have a recursive method that traverses an XML file, writing out the element tag names and values.
This is a snippet from the XML file:
[code]
<root>
<all_companies>
<company_group company_group_ID_attr="1">
<company_group_name>Cleaning</company_group_name>
<company_group_ID>1</company_group_ID>
<company company_ID_attr="2">
<name>Bloomburg</name>
<company_ID>2</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="4">
<name>Morris</name>
<company_ID>4</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>3</employee_ref>
<employee_ref>1</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="7">
<name>Ajax</name>
<company_ID>7</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
<employee_ref>2</employee_ref>
</employee_refs>
</company>
</company_group>
</all_companies>
</root>
[/code]
I use the following XPath expression to access the first <company group> tag:
"root[1]/all_companies[1]/company_group[1]"
On the first call to the recursive method ("swrite_for_select_certain_stuff"),I see with the debugger that I reach the <company_group_name> tag. A recursive call at that point takes me to the text node within the tag ("Cleaning"), but it is a text type node (not an element), so it returns without writing anything to the output stream.
On return from that second call, things go wrong. The Iterator within the while loop returns false for the MoveNext method, when it should have moved to the <company_group_ID> tag (or so I think it should).
Am I missing something here?
OS is Win XP, and .NET is version 4.0.

I need a way to show the display for an element in my list view like so:
[Code]....
Would it be possible to pass in a model to the DisplayFor method?
Maybe a syntax like this:
public static MvcHtmlString DisplayFor<TParentModel, TModel, TValue>(this HtmlHelper<TParentModel> html, TModel model, Expression<Func<TModel, TValue>> expression);
<%: Html.DisplayFor(item, i => i.BarBaz) %>

I've an EntityCollection< T > which contains an element but the Contains method returns false.
I've overriden T's 'Equals' method but the 'Contains' method does not call it (while it's said so in documentation).
When I do foreach (T x in coll), x.Equals(element) returns true.
code:
contains(object entCol, object val)
{
var coll = (ICollection<GraphicSockets>)entCol;
var socket = val as GraphicSockets;
foreach (GraphicSockets sock in coll)
socket.Equals(sock); //true for first element, GraphicSocket's Equals function called
coll.Contains(socket);//false, Equals function not called}
the code i'd actually like to use is
private static bool contains(object entCol, object val)
{
Type entColType = typeof(EntityCollection<>).MakeGenericType(val.GetType());
MethodInfo contains = entColType.GetMethod("Contains");
return (bool)contains.Invoke(entCol, new object[] { val });
}
this worked once but stopped when i started using wcf, i wonder how this contains method works.....

I have a ListView control and under ItemTemplate I have following code:
Code:
<asp:Label ID="Label1" runat="server" Text='<% #MatchCategory(dtCategories.Rows[i]["ID"].ToString().Trim(), Eval("CategoryID").ToString()) %>'></asp:Label>
The MatchCategory method just checks if two values are equal and return true or false. Just below this code I am separately printing dtCategories.Rows[i]["ID"].ToString().Trim() and Eval("CategoryID")
acan see matching values but MatchCategory method always returns false.

I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........

I'm using a model which receives some input from a form and has some validation logic attached via attributes. In one case I'm validating personal names, which should include only letters, apostrophes, spaces and dashes, and be no more than 50 chars long. So I have a model property like:
[Code]....
Everything works fine BUT the RegularExpression attribute: if I add it, I always get a validation error, even when what I type in my form is a valid name (e.g. "Foo"). No matter how I modify the regular expression or what I type, I always get an invalid name error.
(For some reason, I cannot see the regex posted correctly here: it is just ^ followed by the Unicode Letter class and []+ including a Unicode letter class, apostrophe, whitespace and dash, ended by dollar: i.e. start of string - any letter - any of the following: letter, apostrophe, whitespace, dash, 1 or more times; end of string).
What I'm doing wrong here?

Our web application hosted from windows 2003 server, is trying to access a file present in a shared folder of another windows 2003 server. The path for the shared folder is configured in the webconfig file in the below format.
<add key="ReportPath" value="\<Server_Name>Reports"/>
if (!File.Exists(ReportPath))
/ Show the report in a link
This function File.Exists() always returns false and when I try to remove the check, it returned the exception, "Logon failure: unknown username or bad password."

I don't understand how the stored procedure is returning false. It's supposed to continue looping and continue writing rows. Right now it writes the very first row, and then it goes into the If Not AdvanceLinkBanned.Add(banrec) Then and it goes in here, prints the message and exits the sub. Why is it thinking the add returns false? If Not AdvanceLinkBanned.Add(banrec) ? Doesn't this return the id of the new record? Isn't this not zero? Zero would make it false. How can this be false? Isn't it supposed to return the next record created ? Doesn't SELECT SCOPE_IDENTITY() return the value of the record id? How do I test this?

What I'm trying to achieve is to track any change made on a form. I thought DataSet.HasChanges and DataSet.GetChanges would be a good way to accomplish this. However, in the code below DataSet.HasChanges always returns false.
EmployeeDs represents a strongly typed DataSet.how to get changes from the updated row into the new dataSet?

I have some trouble using the openid check_authentication. The answer from the openid providers (I tried with google and myopenid) is always: is_valid:false I do already get the openid.sig and openid.identity but when I try to verify my data with the check_authentication call it always returns is_valid:false. What I have done so far (authentication with google openid in this example, but for myopenid it was the same): I redirect the web user from my page to the following: [URL]
(Without the line breaks of course, I put them in this post only to keep it readable. localhost:104/evalgoogle.aspx is my local test environment) I will then get redirected to the google login page where I can sign in and accept that I will login at Localhost. I unchecked the remember checkbox though. After logging in I will get redirected to the return_to page I set and get the following data in the request:
openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0
&openid.mode=id_res
&openid.op_endpoint=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fud
&openid.response_nonce=2010-02-12T14%3A46%3A52Z1PDyxBssEN9p5g
&openid.return_to=http%3A%2F%2Flocalhost%3A104%2Fevalgoogle.aspx
&openid.assoc_handle=AOQobUfpVnBFYzFO15z92rru88nWjEnw0u8ethVscpjDwkssp8GjVc0u
&openid.signed=op_endpoint%2Cclaimed_id%2Cidentity%2Creturn_to
%2Cresponse_nonce%2Cassoc_handle
&openid.sig=24Hetky5HrNwrY3%2B%2B2vtIGnvmnI%3D
&openid.identity=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fid%3Fid%3D{SOMEID}
&openid.claimed_id=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fid%3Fid%3D{SOMEID}
(where {SOMEID} is my google id) To verify this signature and google id, I composed a webrequest calling the check_authentication as described in openid.net/specs/openid-authentication-1_1.html#mode_check_authentication. My problem now is that this always returned is_valid:false To eliminate possible problems in my webrequest, I now create just a html form with the data I get back from google like this:
<form method="post" action="<%=Request.Params["openid.op_endpoint"] %>">
<div>
<input type="text" name="openid.mode" value="check_authentication" />
<input type="text" name="openid.assoc_handle" value="<
%=Request.Params["openid.assoc_handle"] %>" />
" />
" />
" />
" />
" />
" />
But this also just yields the is_valid:false

I'm using a DataReader to display informations stored in a table. I created Two button to go to next record and to go back. In VB6 I used this code :
While Not Recordset1.EOF
Recordset1.MoveNext
End While
In ASP.NET I didn't find a way to do like it, because DataReader hasn't the EOF property.
EDIT :
While Not Recordset1.BOF
Recordset1.MovePrevious
End While
How can I convert this last code (VB6) to ASP.NET?

The following setup seems to work fine on the client side, however when I post back and check Page.IsValid, the value is false. I also looked at mevDate.IsValid and it's false. It seems that setting the CultulreName on the MaskedEditExtender is sufficient to get the MaskedEditValidator to emit the correct JavaScript, but on the server side of things it doesn't work. When I flip CultureName to "en-US" everything works as expected.

I have a page with a (gridview nested within a gridview) in an UpdatePanel (UpdateMode="Conditional"). The nested gridview drops down when you click on an arrow and then you can click on each subgrid rows command field. The gridviews are loaded from the Page_Load event. When I click on the commandfield in the subgrid the Page_Load fires during the partial page postback. From what I have read this is normal with UpdatePanels. But What I don't understand is why both Page.IsPostBack and ScriptManager.GetCurrent(Page).IsInAsyncPostBack test false after I click on the command field in my grid. I need to stop the rebinding of the gridviews ( which causes the subgrid to collapse ) when the command field is clicked.Also: I am using MasterPages and the <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> is located in my mater page form section.Would anyone have any suggestions how to test if a partial page postback is occuringHere is a link to the page source: http://pastebin.org/153774here is a link to the code behind: http://pastebin.org/153781

i have two data tables with the same structure
the first one has one row of the second one
the second one has set of rows
what i want is to get the row which comes next to the row of the first data table in the second data table.
the first data table his name is :: temp
the second data table his name is :: dt
i do the following:
DataTable temp = new DataTable();
temp = dt.Clone();
DataColumn[] keyColumn = new DataColumn[1];
keyColumn[0] = temp.Columns["photoId"];
temp.PrimaryKey = keyColumn;
temp = (DataTable)(Session["currentImage"]);
DataRow[] drr = new DataRow[1];
index = dt.Rows.IndexOf(temp.Rows[0]);
but the index always comes with one value = -1
although the temp.rows[0] its contents changed all the time
when i write dt.Rows.IndexOf(dt.Rows[1]) for examble i get 1
but this is not what i want to do ,, what i want to do exactly is to get the datarow next to the datarow of the first dataTable in the second dataTable

I'd like to be able to determine what class will be called given an URL. For instance, I have a page /First.aspx that has a hyperlink to /Second.aspx In the code behind for First.aspx.cs, I'd like to be able to determine what class will execute if someone clicks on the hyperlink that points to /Second.aspx.
EDIT: One of the reponders asked me to outline the problem I'm trying to address. Here it is: The codebase I inherited has a subclass the System.Web.UI.Page that has a public Authorized method that returns a boolean. The Authorized method checks the parameters passed via the query string against the authenticated user, and determines whether that user should be allowed to call that page with the given parameters.
Elsewhere in the site I have hyperlinks that reference those protected pages. In some instances those links are displayed to users who are not authorized to navigate to that page. They can click the link, however they get an error. In other instances, prior developers when through the trouble of inserting logic that hides the hyperlink for those unauthorized users, but the authorization logic is duplicated (In the page itself, and in the linking page). What I would like to do is create a subclass of the hyperlink class, and have the subclass inspect the NavigateUrl, determine the destination page class, and call the Authorized method of that class to determine if the user is authorized to call that page. If the user is not authorize, the link will automatically hide itself.

I have developed a web application 3 months ago to show facebook users by searching username. To access facebook, I have downloaded facebook dll and got application key, and secret key from facebook. My web application was working fine and displaying records from facebook. yesterday onwards, my application is not working fine. I could not get response when I search by name. I have tested the fql in the facebook testAPI tool online. That time i can get response. but the same fql i used in my appliation but it could not get response from facebook when I search by name. If i search by uid i can get response from facebook. here is my code.
facebook.Components.FacebookService fb = new FacebookService();
fb.ApplicationKey = "bfeefa69afdfe81975f0d6136ace3009";
fb.Secret = "9b672d682e1d8befd06382953fc2615b";
fb.IsDesktopApplication = false;
//the below fql gives response as xml.
//select name, profile_url from user where uid = '1730923544' -I can get response for this fql.
//the below fql does not give response as xml. But it gives empty string.
//the below fql does gives us response as xml when i try in facebook testAPI.
//select name, profile_url from user where name = 'Suresh Rajan' -I couldn't get response for this fql.
string s = fb.fql.query("select name, pic_square, profile_url from user where name = 'Suresh Rajan'");
if (String.IsNullOrEmpty(str1))
Response.Write("Empty Response");
else
Response.Write(str1 + " ");
how to search by name in facebook fql.
