DataSource Controls :: Internet Connection Loss While Executing Query?
Jun 23, 2010
I am having problem in diffrentitate error between internet connection loss error and Other Error in query for example: duplicate record found.
Both the error fall into System.Data.SqlClient.SqlException category.
But the way to handle both this 2 error is different.For connection error , i need to bring user to connection loss page while for duplicate record found error, i need to show the user a pop up.
Unless i do a checking exactly on the error message , else i have no ways to differentiate connection loss error and any other error. Am i correct for this?
I have an article submission system on my website whereby a user inputs a bunch of information and submits it to the database. After the user presses the "submit" button, apart from submitting the article to the database, I want to also execute another rather large SQL query that inserts additional data into a seperate table.
However since this execution may take a while, I do not want the user to have to wait for the query to be successfully completed before they are forwarded to the "submissionsucess.aspx" page. In other words I would like the larger sql query to take place while the user is still on the website. So I was wondering if there is a way to do the following:
1. User submits article.
2. Simple submit query is executed.
3. Submit query is finished...start complex longer query (takes time).
4. User is forwarded to success page, user then continues to browse website. Complex query still executing at the same time, while user browses website.
I want to use from two db connection in one linq query
My sample is:
int a=1; if(a==1) DataClasses1DataContext1 db = new DataClasses1DataContext1(); else DataClasses1DataContext2 db = new DataClasses1DataContext2(); var q = from c in db.F_Groups select c;
In this code a=1 so db connection is DataClasses1DataContext1
I want if a=2 then db connection = DataClasses1DataContext2
but this code is error.
db connections is completely same but in two deferent class a db connection is sql and another is oracle
In my DAL i have more than 100 methods/Function, each and every method am opening the sqlconnection and closing the connection, this is taking too much of time to establish the connection at every time. So what i expect is one common class will create the SqlConnection that will check if the connection is Broken or Closed then create the connection again else return the connection, how to do this(Also i would like to apply ConnectionPooling).
I have written a routine to delete a record from a table. I want to include a statement to 'close' the connection to the table but I do not know the syntex of the statement that will do this. My code is as follows:
I have a web project that sends out a customized email after certain user events (like a status change). I also have an SSIS package on the database that pulls in data from one database and updates another database with that data. I want to be able to compare the data and if a particular field's data for that record is different between the two databases is different, I want to be able to use the dll I created for the web app to send the appropriate email.
We have about 500 scripts that we are modifying at development server . These modified scripts have to be run at the live server .
Well instead of running each script, we are thinking of a platform independent application (If we develop in dotnet the user(DBA) has to have dotnet framework installed,hence i am not thinking of a dotnet application) which will execute the script.
(These scripts will be enclosed in a folder and sent to DBA. Through the newly developed application the DBA should be able to browse this folder and on clicking a particular button the scripts placed inside the folder should run.)
Basically such an application should be able to connect to the database and run the scripts that we saved in the folder....
I am having a domain name and web space (the web is running, its ASP.net 3.5). I am working on a project in which I need to connect 2 computers over the internet.
Is it possible to do that with a simple ASP.Net website? What other things I do need to do this?
EDIT Actually I want to send the data from one computer to another in real time, I mean as we do chatting we exchange text to one another. The same thing I want to achieve.
i am having a problem in executing the SSIS package through an asp.net application. i'm using c#. every time i run the package through web, i think the package is not disposed properly so until and unless i stop the application the package won't execute...i am not able to dispose or unload the package. i'm geeting errors like
'WebDev.WebServer.EXE' (Managed): Loaded 'C:WINDOWSassemblyGAC_32CustomMarshalers2.0.0.0__b03f5f7f11d50a3aCustomMarshalers.dll', Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled. The result of the expression ""EXEC " + @[User::vRowData]" on property "SqlStatementSource" cannot be written to the property.
The expression was evaluated, but cannot be set on the property. : Package Execution results: {0}
and so on (many more records). Now, whenever a record reaches its' end time, how can I execute SQL commands to delete that data (or mark as finished) and UPDATE another table?
This needs to be running constantly so I was thinking of building it into a Windows Service but can you suggest a better way of doing it?
I have a WCF service that processes some input arguments and retuns result in approximately 4 minutes. Sometimes the calling client may get request time out before the WCF service answers.
Now, my customer is asking me to stop processing on the service side when the client got timed out. Since, I could not know the status of cleint on the service, I could not stop the process.

I am excuting SQL Query using Nhibernate, here is my code
public ArrayList getDocumentsForApproval(string ReleaseId) { string query = string.Format("SELECT distinct doc.Id, doc.Name as Doc, doc.url as url, suser.Name as Author, ds.name, CONVERT(VARCHAR(11), doc.DateEntered, 101) as DateEntered FROM dbo.Documents doc INNER JOIN DevelopmentSteps ds ON doc.TypeId = ds.Id INNER JOIN DocumentTrackingItems dti ON doc.Id = dti.DocumentId INNER JOIN TrackingItems ti ON dti.ItemStepId = ti.Id INNER JOIN dbo.Releases rl ON ti.ReleaseId = rl.BugTrackerName left outer join (select * from users) as suser on doc.AuthorUserid = suser.Id WHERE doc.DateEntered IS NOT NULL AND doc.DateApproved IS NULL AND rl.ID = '{0}'", ReleaseId); ISession session = NHibernateHelper.GetCurrentSession(); ArrayList document =(ArrayList) session.CreateSQLQuery(query).List(); return document; }
Exception Details:
NHibernate.QueryException: Return types of SQL query were not specified [SELECT distinct doc.Id, doc.Name as Doc, doc.url as url, suser.Name as Author, ds.name, CONVERT(VARCHAR(11), doc.DateEntered, 101)
I open a sqlconnection and sqlcommand. I execute a stored procedure and get the scope_identity from that procedure to be used within another procedure that needs to be fired. Unfortuntley if the second procedure fails forwhatever reason the data change for the first procedure commits anyway. I kind of want to do a began transaction end transaction on the c#.net side. Also I need to execute a stored procedure multiple times....
i have few variable in login page that is read from db.If the internet connection is loss suddenly during read process, my frst page is not able to be loaded and show to user.I am thinking to have this page show when internet connection lost. Is it possible to do so?The page is shown as the picture below :
I'm trying to figure how to on a submit button execute an sql file.
We have a job recruiting application, and for the subsidiaries companies they all have their own database setup for the jobs. At night the application has a consolidator script built in to pull all the jobs posted in those companies and load the posting into the parent companies website job listing. This listing will then point back to the Subsidiary website for the applicant to apply.
The issue with that script is the time it took to execute which is 20hrs to run as a scheduled task. We have created a more efficient script and would like to place a submit button in the admin panel for the HR recruiters to click which will automatically upload their updated job listings to the parent company.
So what would be the proper coding framework to use on the submit form to execute our new consolidator sql script?
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
