When the page loads I am able to click the add button and it moves the selected person from one dataset to the next. If I then try to move another person I get the error message 'Cannot find table 0'. I have changed the text to bold where the error occurs.
Here is my code

How can we find the ip address of a person who has logged in?
View 1 RepliesI am somewhat new to c# so I am unfamiliar with data access. I have used PHP but it is obviously less strict of a language than any form of dot net. With some help I have put together a try/catch sequence that outputs the below error message using a 'sqlex.Message'
Invalid object name 'nwsb_tbUsers'.
I am a bit confused about the error message though because the "tbUsers" table does exist inside of my MDF database that I created it via FTP. Is something wrong with my connection string possibly?
<add name="connectionString_dbInfo" connectionString="Data
Source=tcp:s01.winhost.com;Initial Catalog=MYDBNAME_sql;User ID=MYUSERNAME;Password=MYPASSWORD;Integrated Security=False;" />
I copied this directly from my host so I would like to think that the connection string is correct. I can access the table and modify it via FTP.
I try to create a webbased application with vb 2010 and asp.net 4.
I have a main loginpage, from there users are redirected based on their roles, I have 2 subdirectories and a admin page. User are being redirect so that is not the problem, but when for example, I am on subdirectory 2 and type in the addressbar the mainpage of subdirectory 1, I am redirected to the loginpage and still being loggedin (I see the login page but also my username in the upper right corner). What suppose to happen, is when a user types an unauthorised url, they should get a 403 access denied page (because it should not be possible to go directly to an other sub folder) and return to their previous page.
In every subdirectory folder I have a web.config with authorization on allow and deny access.
I have a table in my aspnet database. I added a bottom row "Not Selected", if the user doesn't select from a databound drop down list. This row is at the bottom, because I just added it to the table data. Is there any way to move this one row to the top of the table manually? There is not "cut" and "paste" when I select the whole row.
View 3 RepliesI'm using vs2010. I have a left column simular to a navigation area and I'm trying to figure out a way to display the FK links that appear at the end of a list as columns, in my navigation area. One thought was to place a duplicate table in the navigation area and hide all the columns except for the FK links. Is there an easier way to accomplish this.

Having deployed a new build of an ASP.NET site in a production environment, I am logging dozens of data errors every second, almost always with the error "Cannot find table 0." We use datasets and frequently refer to Table[0], and while I understand the defensive coding practice of checking the dataset for tables before accessing Table[0], it's never been a problem in the past. A certain page will load fine one second, and then be missing one of its data-driven components the next. Just seeing if this rings a bell for anyone. More detail: I used a different build server this time, and while I imagine the compiler settings are the same on both, I have a hard time thinking that there's a switch that makes 50% of my database calls come back with no tables. I also switched the project to VS 2008, but then reverted all of those changes when I switched back to VS 2005. I notice that the built assembly has a new MyLibrary.XmlSerializers.dll, where it didn't used to, but I also can't imagine that that's causing all the trouble. (It also doesn't fall down on calls to MyLibrary, or at least no more than any other time.)
Updated to add: I've discovered that the troublesome build is a "Release" build, where the working build was compiled as "Debug". Could that explain it? Rolling back to the build before these changes fixed it. (Rebooting the SQL Server, the step we tried before that, did not.)
The trouble also seems to be load-based - this cruised through our integration and QA environments without a problem, and even our smoke test environment - the one that points to production data - is fine under light load. Does this have the distinguishing characteristics of anything you might have seen in the past?

By default in login template, in case user key in the wrong user name or password, the literal message will show the default error message, "Your login attempt unsuccessful..."What i trying to do is, I have a function in my system to disapprove a member, after the member is disapproved, he/she will not allow to login anymore. When the user trying to login, the default literal msg will show out. Is there any way i can do it more specifically like if the user enter the wrong password only, the literal msg show: "Wrong password entered" insteaed of the default msg?
Same goes to the change password control, for any error msg it just show the long msg but does not tell user whats wrong with the entered valueim trying to do something like if the user enter the wrong password, the literal msg show the one i wan to show.

moving some tables & stored procedures from SQL Server 2000, to SQL Server 2005.So far so good, but I've come across a problem with this stored procedure:

i want to get data from database of field Name and Gender, and then display it in Label name and gender. when i click save it move to next record and display name and gender that next record.
, I've researched this quite a bit and I'm just not seeing the problem. The app runs beautifully when living on my pc - the app on my pc connects successfully to the SQL Server 2008 Express Database (which sits on a server - not my pc). However, as soon as I publish this application to the server that the SQL Server 2008 Express Database sits on, I get this error when I try to run the application:
ERROR [42S02][Microsoft][SQL Server Native Client 10.0][SQL Server]Invalid object name 'user'
It's behaving as if it either doesn't know where the table is when the app tries to run on the same server as the database or maybe the app doesn't have permission to hit the database once the app is on the same server as the database. I have connections on my pc and the server defined for this database, I verified that I set up each connection the same. I've also tried connecting using [dbo].[user] and this doesn't remedy the situation either. my connection string is in my web.config and it looks like this:
<add name="directoryConnectionString" connectionString="DSN=directoryProd" providerName="System.Data.Odbc" />
my sql looks like this:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
connectionstring="<%$ ConnectionStrings:directoryConnectionString%>"
ProviderName="System.Data.Odbc"
SelectCommand="SELECT fName FROM [user]"></asp:SqlDataSource>
I have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.

All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:
[Code]....
So how can i just return ViewData["SqlError"] message in page.
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
We have an already existing project on IIS and we want to move to Apache (windows) with mod_aspdotnet. What things could not work? If we use 3rd party DLLs? Will office components work fine (export to Excel, Word, etc). If you have any experience on this type of migration, I'd like your inputs! Also, is there another alternative to mod_aspdotnet?
