Aug 20, 2010
I have table A in database A , in table A i have trigger to insert record to database B table A, each update and insert of database A -table A, triiger fire and insert record in database B table A, when i try to update some times asp.net application gives error
"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
and then error log says System.Data.SqlClient.SqlException: Database 'database B is being recovered. Waiting until recovery is finished.
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)[code]....
I'm using the ASP.Net Membership provider, but I don't want to allow system administrators to DELETE any users. Instead, I simply want to mark them as locked out (aspnet_Membership.IsLockedOut) of the system so they can't log in when an administrator assigns them to a role titled "Inactive". Make sense? Right now my trigger isn't throwing any errors, but it's not working either. Here's my trigger (which is on the aspnet_UsersInRoles table):
In my asp.net website I am creating a session upon user login and I would like to perform some operations in the database just before this session will expire.I am having problem in determining where should I write code and how will I know the session is going to expire.
I am not sure if 'session_end' event of 'Global.asax' suits my requirements as the session I want to check is created manually(not a browser instance).
I am trying to use SqlDependencyCache buthave come across a problem that I wouldn't have thought was unique. We have a InformationDatabase which uses a combination of its own tables and views to other databases on the same server. One of these views points to our HRDataWarehouse database. My stored procedure obviously uses this view to get its information but because the table change is happening on the HRDataWarehouse table the notification is not being sent to my app and as a consequence the cache is not removed.
Is there a tidy way of doing this or do I need to create a trigger to update a table in my informationdatabase and then have a listener on this with a removecache callback delegate added to the cache object?
I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
I have update panel , in update panel i have one button control which exposes onlientClick event ( it dosent have click event to do postback to server).
and i have one updateprogress panel. So my problem is though i'm performing operation on client side , internally the async event is firing and making updateprogress panel to act (having rotation gif image) which i dont want , as it rotates for 10-15 sec more even after the operation at client side is done !
I have an asp.net web page which works with a database. When I first upload it I never disposed the connections so after using the different modules of the application for sometime it would suddenly stop working saying the connection pool filled or something like that.To fix it when a user clicked a button I opened the connection, tell the database what I needed and finally disposed the connection.
This seemed to fix everything, in fact you can work with application all you want, the problem comes if you stop using it for certain time.So for instance, I have a module in my webpage where user can capture information for a certain product. When the user clicks in one button the info gets into the database. If the user is continuosly capturing data everything works fine, but if it goes for about 10 min when he clicks the button he will receive an error. To fix this the user has to log-in again.
Every module opens a connection to the database to verify the user identity, but then after it verifies it I dispose the connection so I don't think there is a problem.
I'm running a website on a SQL 2008 database. At the moment most of my data is in cache but what I want to do is be able to update the data on a regular basis, say every 3 hours, maybe more frequently. Obviously I can set the cache to expire and pick up new data, but how can I replace part of the database (because some tables are populated by the user) in the background, so that when the cache expires the new data is picked up?
I notice when I upload data through VS, it wont let me upload if the DB is in use - so how do I get round issues like this?
I need to use caching in my project. The problem is that, When page is firstly load ı cached a dataset. Then after after I update or insert a new record in table. my dataset returns from the cached records.
I have created normalised data tables to hold look up information (such as venues, players, teams etc) and want to dynamically update the 'matches' data table (my transactions) using webpages instead of running SQL queries.
What I want to do is select a name from a drop down list and then post the relevant ID associated with that name to my 'matches' table. At the moment I can only link to the value in the drop down list, i.e. the name which is incompatible with the validation which expects a primary key integer.
I'm sure this problem is a fairly common one but I haven't found the right answer on any of the tutorials or blogs, all of them assume that the data is de-normalised or describe things in more technical ways than I can yet understand. If anyone can point me to a 'how to article' or tell me what I am doing wrong, I would be grateful.
Am trying to build a page that will display one record at a time. That is the user searches a records table and the page displays the record. Than when the user us done making any changes and clicks save, i want the page to update the records table. So far, i have the page displaying the search results, but the save functionality is not working. Actually after changing an entry and the save button is clicked, the records change are currently reverting back to the old data that they want to change it from. How do i go about updating the records in the database? Here is the code that I have been able to come up with so far.
And in another page i am displaying the list of all the dynamic database tables. Here user selects table from gridview and the data is displayed to him in dynamically generated HTML Table with Dynamic textboxes. (This part is also running ok)
Code:
// Display data protected void getTableInfo() { int RowNo = 0; string NotCmd = "Select * From NTL Where InfoCode = @InfoCode";
[Code] ....
Now the problem is how to update the record in database through this dynamically generated html table and texboxes. When I run my dynamically generated update command, all the dynamic controls is lost in postback.
I'm working on a new project where I have the luxury of working from a Model to Database approach using Entity Framework 4.
The project I'm working on is taking an agile approach where different phases will be rolled out over time.
Will the Model First approach work in my case? I noticed when you "Generate Database from Model" it recreates the entire schema from scratch which will obviously wipe all the data that is in the db. I was hoping for a more "Update Database from Model" approach where the db would just be altered to reflect the changes rather than recreated
is there an easy way to update a user control from another user control? i have a input box and a submit button. the user inputs a code, hits sumbit and based on the code, points are applied to thier score (another user control). the points are applied to the score in the database but don't show up on the page display until i hit refresh. is there an easy way to update the control on submit?
protected void btn_Add_Coupon_Click(object sender, EventArgs e) { try { SqlDataSourceTEST.DataSourceMode = SqlDataSourceMode.DataReader; IDataReader Reader = (IDataReader)SqlDataSourceTEST.Select(DataSourceSelectArguments.Empty); if (Reader.Read()) { int iPoints = 0; iPoints = (int)Reader["Points"]; if (iPoints > 0) { Profile.TimesVisited = Profile.TimesVisited + iPoints; lblcoup.Text = iPoints.ToString() + " have been added to your score!"; } else { lblcoup.Text = "Coupon Code Not Valid"; } } Reader.Close(); Reader.Dispose(); } catch (Exception ex) { } }
I have an UpdatePanel with ContentTemplate specified. When page loads, user can do some AJAX work in other part of the page. Then, after that work is finished, I would like to update only content inside UpdatePanel, but without pressing any buttons etc. I should be done automatically using JavaScript when previously started AJAX work finishes. How to do it without manual clicking on the trigger button?
EDIT:
Ok, I've followed that _doPostBack rule, and whole page is posted.
i need trigger function for update. if a change value of a column in one table. The value of different column from the second table should update the value in the third table.
My issues here is that this does not compile. I get "A control with ID 'LinkButtonRemove' could not be found for the trigger in UpdatePanel 'UpdatePanelFiles'." What I am trying to do is have two buttons in the item template. One that updates just the ITEM and one that updates the entire DataList. "LinkButtonRemove" is what I want to update the entire datalist. Any ideas on why this isnt working? Or how to do what I want to do?
THE SHORT VERSION: UPDATEPANEL1 -DATALIST --ITEM ---UPDATEPANEL2 ----CONTROLS
I want one control to update the item updatepanel only and the other to update the entire datalist.
I would like to add a button to Update panel's trigger. But am getting an err says "Update panel can not find the button which trigger it".
I am getting "Sys.Webforms.PageRequestmanagerParseErrorException: This message recieved from manager could not be parsed. Common cause for this error are when response is modified by response.write"
I want to create a trigger for insert and whenever i insert the data the trigger should fire and notify some value inserted i want to create log table to save this information,now i have created a trigger but i dont know how to map it to log table to notify the changes?
