Can Update Some Records In A Database Correctly

Mar 14, 2011

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:

string userName = Request.LogonUserIdentity.Name;
if(true == string.IsNullOrEmpty(userName))
{
logger.logwarning("missing username");
}
else
{
logger.loginfo("update by {0}", userName);
}

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.

Merge The Records From The Database On The Local Machine With The Records On The Remote Server?

Mar 31, 2010

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?

DataSource Controls :: Copying SQL Server Database Has Not Copied Membership Stuff Correctly?

Jan 19, 2010

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?

SQL Server :: SqlDataAdapter Update Returns 0 Records?

Jan 25, 2011

using ASP.NET 2.0 SqlDataAdapter update returns 0 records. I have a simple application that stores Passenger's ticket info in a sql database.

when a user clicks "Create Reservation" I add a Passenger Information (name, destination, PNR) to dataset
and save dataset in ViewState.

Then when user clicks update, I pull the dataset from viewState and try to update database. The update is returning 0. what i am doing incorrectly?

protected void btn_CreateReservation_Click(object sender, EventArgs e)
{
DataRow dr ;
dr = dt.NewRow();
dr["Name"] = txtBox_Name.Text; dr["Destination"] = txtBox_Destination.Text;
dr["PNR"] = Convert.ToInt32(txtbox_PNR.Text); dt.Rows.Add(dr);
dt.AcceptChanges();
ViewState["MyTable"] = dsPassengers;

DataSource Controls :: Update Records Of A Sqldatasource That Is Used For A GridView?

Dec 14, 2010

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?
