Security :: VB.NET Returns System.String[] Instead Of The Actual Value Of The String
Dec 24, 2010
I have two sub routines that I've created to pull in my Membership user roles and assign the value/name of that role to the value of a cookie.
My first subroutine looks like this
[Code]....
At this point, role ID is a 1-dimentional array which is not acceptable for a cookie's value (it must be a string), but in Debug mode, I can see that the array does contain the correct roleID value. In my 2nd subroutine I change the value from array to string for no other reason than that it gives me an opportunity to see that the value of CookieValue() before it is converted does have the correct roleID.
[Code]....
Even though it still shows that string as having the correct value, it returns the object "System.String[]"

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

In my code below, I'm trying to re-write a string and convert and http text into actual web links.
It doesn't seem to be working and I think the problem may be that I'm rewriting the string and inserting another http string into the original string which then causes problems with the loop.

With script below, request to the server always sends empty string (even if value is not emtpty), where the data line is:
data: "{ 'folderName': '" + $(this).val() + "' }"
The html element under investigation is this:
<asp:TextBox id="searcher" runat="server" ClientIDMode="Static" CssClass="classificationFolder" />
Script is:
<script type="text/javascript">
$(document).ready(function () {
$(".classificationFolder").each(function () {
[Code]....
The reason that I select elements by css class selector ($(".classificationFolder")) is that, this control is a user control and used in the same page more than once. That is why I'm not using $("#searcher").
I tested the code In IE8 and Chrome 8.0.552.28 beta. This issue is arising in both of the browsers.
On the other hand, request is sent to the server, client received response successfuly and response is processed on the client.

Why does this
string test = "Text1, Text2";
string [] tests = test.Split(", ".ToArray());
returns this
[0] = "Text1"
[1] = ""
[2] = "Text2"
what's with the quotes in tests[1] ? I thought the output would be like this
[0] = "Text1"
[1] = "Text2"

I'm trying to encrypt some userData to create my own custom IPrincipal and IIdentity objects using Forms authentication - I've serialized an object representing my logged in user to Json and created my FormsAuthentication ticket like so:
string user_item = GetJsonOfLoggedinUser();/*get JSON representation of my logged in user*/
System.Web.Security.FormsAuthenticationTicket ticket =
new System.Web.Security.FormsAuthenticationTicket(1,
WAM.Utilities.SessionHelper.LoggedInEmployee.F_NAME + " "
+ WAM.Utilities.SessionHelper.LoggedInEmployee.L_NAME,
DateTime.Now, DateTime.Now.AddMinutes(30), false, user_item);
string encrypted_ticket = System.Web.Security.FormsAuthentication.Encrypt(ticket);
HttpCookie auth_cookie =
new HttpCookie(System.Web.Security.FormsAuthentication.FormsCookieName, encrypted_ticket);
Response.Cookies.Add(auth_cookie);
However, the string encrypted_ticket is always null. Is there a limit on the length of the user_item string?

This is completely frustrating and probably embarrassing as well. A while back I posted a similar question and resolved the issue. [URL]...scope_identity The program has been working ever since, until yesterday when as it turns out SCOPE_IDENTITY() started returning an empty string even though a record is being inserted. I am not sure what has changed since the fateful day.
[Code]...
I am hoping that there is something I am just not seeing here. A lot of the information I have seen thus far indicates that there are problems with SCOPE_IDENTITY() but most of those are related to inserting multiple records. As you can see this should be fairly straight forward. The thing that really has got my goat is that it used to work and now it doesn't. If someone could take a look at the above code and comment on any anomalies it would be great. Also I have heard suggestions for switching to ADO.NET and it is beginning to look a lot more attractive every day. But I have a ways to go before making the switch so it is SqlDataSources for now

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.

I have an issue with some content that we are downloading from the web for a screen scraping tool that I am building.in the code below, the string returned from the web client download string method returns some odd characters for the source download for a few (not all) web sites.I have recently added http headers as below. Previously the same code was called without the headers to the same effect. I have not tried variations on the 'Accept-Charset' header, I don't know much about text encoding other than the basics.The charachters, or character sequences that I refer to are:
""
and
"Â"
These characters are not seen when you use "view source" in a web browser. What could be causing this and how can I rectify the problem?
string urlData = String.Empty;
WebClient wc = new WebClient();
// Add headers to impersonate a web browser. Some web sites
// will not respond correctly without these headers
wc.Headers.Add("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12");
wc.Headers.Add("Accept", "*/*");
wc.Headers.Add("Accept-Language", "en-gb,en;q=0.5");
wc.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7");
urlData = wc.DownloadString(uri);

I have defined an ODBC Command and ODBCdatareader as follows
OdbcConnection myConnection = new OdbcConnection(connectionString);
OdbcCommand myCommand = new OdbcCommand();
myCommand.Connection = myConnection;
myCommand.CommandText = "select UOPGM from GREG.TUSROPTF";
OdbcDataReader myReader;
myConnection.Open();
myReader = myCommand.ExecuteReader();
When I try to retreive from the reader as follows:
while (myReader.Read())
{
string someString = myReader["UOPGM"];
lstNames.Items.Add(someString);
}
I get the following error
Error reading the database. Unable to cast object of type 'System.Byte[]' to type 'System.String'."
I have also tried string someString = (string)myReader["UOPGM"]; to no avail

Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.
