I have an ASP.NET web form application that on the server side I need to know the user's identity. I do not need to impersonate the user. I just need their username so I can update some records in a database correctly.When the request is processed I have the following line of code:
In my development & QA environment this works perfectly - I see the userName in the log file and all of the database records have the lastModifiedBy field filled in correctly. However, when we go to production - userName is an empty string.
I have in my page an edit button and textboxes. I want to edit one single record from the database to these textboxes. I wrote the following code, when I click the edit button then I have the results. The results load in my textboxes. But when I try again to run the page with the same ID for second time then I have this error 'Specified cast is not valid.' What's going wrong? I used int ID=3; to get the 3rd record in this example
I am doing update query to edit my records and save to my database...I am getting the query expression exception...syntax error (missing operator) in query expression 'WebLogin=krish'.
string strUserName = Request.QueryString["UserName"].ToString(); DateTime dateTimeNow = DateTime.Now; string ConnString = ConfigurationManager.ConnectionStrings["Data"].ConnectionString;[code].... I am getting the exception syntax error (missing operator) in query expression 'WebLogin=krish'.
I have added two update panels to my page. I'm trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.
The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?
I get the error after uploading my ASP.NET solution to server:

I have a login in my admin page. Now I want to log every login-try in my database. Normaly I have a Log-table with the adminID in a foreign key of the adminuser-table. Now, of course, when someone try to login with a username that doesn't exist, I haven't a ID and the foraign-key uses a crash in the write-attamp. Now whats the correct way to log a login-try when the username isn't correct and you haven't the correct id?
I have a gridview with a select command.. When user selects a row.. I need to populate 4 dropdownlists with the values in gridview, dropdownlist which are also populated at page load event...

I have just used the Import and Export Wizard to copy my production SQL Server database, which uses Membership and Roles. I used the option to copy all the data from existing tables and views and did not modify the mapping in any way. Things do not seem to have gone well.....
My source database has a bunch of views with names like vw_aspnet_Applications,vw_aspnet_MembershipUsers, etc. The copy database has these listed as tables!I wondered if running aspnet_regsql.exe might fix things. I needed to run this anyway to create all the missing stored procedures for Membership, etc. However, it failed with the error:Setup failed.Exception:An error occurred during the execution of the SQL file 'InstallCommon.sql'. The SQL error number is 2714 and the SqlException message is: There is already an object named 'vw_aspnet_Applications' in the database.Creating the vw_aspnet_Applications view...I am a bit lost. All I want to do is to create a total clone of my production database for test purposes. Where do I go from here?
I just spent the last week and a half working on a gridview for a user and now he says he wants it so that all the records are updatable! He doesn't want to click on the Edit button, he just wants everything open for update. Is this possible? Or would anther control do it?
When I want to update records in a table, I usually invoke as shwon below:
[Code]....
This code works fine. But when I'm trying to update multiple records using IN clause, it does not work. Can any one tell me how to do it using IN clause?

Here is my situation: I use the SqlCommond to update some records in the SQL Server in a ASP.NET web site. Users can choose which records they want to update. Sometimes they may choose 40 or 60 records to update at a time.Is there any good way to do it? I do not want to do like it
I have a table line (ID, LineNo, LineName) having values as :
1, 1, <blank> 2, 2, <blank> 3, 3, <blank>
ID is PK with Auto-Increment and LinNo(I am manually incrementing through ASP.Net Page while record insertion) Now i have to write a query such that it updates LineName column from line table which is blank(as shown above) with values from table linet(linenamet) having values as :
a b c
My trial query is : update line set LineName = (select linenamet from linet);
It gives ERROR as : Subquery returns more than 1 row Expected Result : After Updation it should show line table as : 1, 1, a 2, 2, b 3, 3, c

I'm executing an update stored procedure from LINQ to SQL and I need to know the records affected after the update is called. I'm using dbml designer to generate the LINQ code.
i couldnt find a specific answer to this question, i am relatively new to .net :)
i have a gridview that is displaying data from a sqldatasource in my page_load event. i need to loop through the records and update each value of a particular column BEFORE being set into the GridView.
i have tried converting to a data set and looping through updating the values, however it seems that one i initially run my query the values get set right into the GridView and i can't update them after that.
Do I need to add one of the GridView functions like Databound and do the loop in there?
