Getting An Error While Fetching The Records From Sql Server To Datagridview - Timeout Expired
Jun 8, 2011
I am getting an error while fetching the records from sql server to datagridview. Ex. I have 10 rows in datagridview first five are with one table and next five for another table. When loop goes for next table it throws an error like "timeout expired. the timeout period elapsed prior to completion of the operation or the server is not responding. The statement has been terminated."
for (int h = 0; h <= dtgqueformat.RowCount - 2; h++)
{
string avl_subject = dtgqueformat[8, h].Value.ToString();
string avl_chapter = dtgqueformat[9, h].Value.ToString();
I'm not sure if this is a VB.NET error or SQL Server. But I get the above error with following stack trace:
[SqlException (0x80131904): Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.] System.Data.SqlClient.SqlConnection.OnError(SqlException
My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application.
I am working on uses the ThreadPool class and specifically the QueueUserWorkItem method to launch its background tasks. I am however having an issue related to SqlConnection timeouts. My error is this: "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
This code is using all available ThreadPool threads because it is processing nearly 100,000 items, each on a threadpool thread, and updating an SQL database. So my question is this? Has anyone ran into a similar problem or could shed some light on a resolution to this issue? In testing, if I use the threadpool. setmaxthreads function and give it a value of 100 (to match the default Sql connection pooling count) then all runs just fine, but much to slow to process this much data.

The following is my connectionstring: server=(local);database=JnJ3;uid=sa;pwd=sa May I know how can I avoid timeout expired because I keep on receiving error message when deal with huge amount of data. The timeout period elapsed prior to completion of the operation or the server is not responding.
am using vb.net 2008 and sql server 2008. I have a search form and when i search at times, I have "Connection Timeout Expired" error.I dispose and close the connection after establishment, but i still get it. tried setting MyConObj.ConnectionTimeout = 0 and it also gives me "Property ConnectionTimeout is ReadOnly.
I am connecting to a vendor-supplied Web Service running in our domain and am attempting to execute one of its methods. I am receiving the error below (Timeout Expired) and not sure how to fix it. The server is running SQL Server 2000 (soon to be upgraded!) and I have checked the timeout setting which is set to 0 (unlimited)

I have an application using taskfactory that creates multiple tasks which insert records into the same table in a database. I have jobs that cleanup the table when it gets too large and have the execution time-out set to 0 in options in sql server management studio. I keep getting the following error on the tasks when trying to do an insert using a stored procedure and set an exception handling process to sleep and try again. This does not help as it seems it timeouts on almost every attempt.Not sure how to handle this and ensure the table handles all these inserts. Tried including connect timeout = 600 in one of the processes connectionstring but this did not help.Also set sqlquerytimeout value in registry to 90 but still not helping.
ERROR: timeout expired the timeout period elapsed prior to completion of the operation or the server is not responding...
could not see the details of the error since visual studio 2010 debug options had to be set that way, but I will set a responsestream and capture but I rebooted sql server and somehow everything is fine now...not sure why.
Errors have reoccurred. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
I am working with synchronizing 2 databases (SQL Express and SQL Compact Edition) using VS 2010. It works fine when the program first running. However the SQL Command "Timeout expired" Exception occurred when the code has been executed for several times. The error message is:
IE9 gives webpage expired error suddenly on any process of my page. Any action I do like edit, add or delete.. after some operations .. page suddenly says expired message in IE9 only.

I am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers locations
Table computers looks like thisID is the primary key column) ID Location Computer139 Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).
I fetch data from an SQL Express database table named ALARMLOG to a datagridview1. One of the columns of ALARMLOG is "TheTime" which has datetime data type values. This values are in the following format "22/04/2010 13:23:45 PM".When I fetch the data to the datagridview1 I get "22/04/2010 13:23 PM".The problem is that I can't display the seconds in datagridview1. I tried the CORVERT command of SQL in order to convert from datatime to varchar but nothing...
We got a legacy vb.net applicaction that was working for years. But all of a sudden it stops working yesterday and gives sql server timeout.
Most part of application gives time out error , one part for example is below code :
CODE:
It was working and now gives time out in command3.ExecuteNonQuery()
Some information : There isnt anything that has been changed on network and the app uses local database. The main issue is that even in development environment it donest work anymore
I have written a store procedure which retrieves more than 7000 rows. While executing the store procedure in my VB.NET winforms application, I'm getting an error like as follows."Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."I googled and tried like using these lines of codes which wasn't useful.
sqlCmd.CommandTimeout = 0 sqlCmd = New SqlCommand("waitfor delay '00:00:60'")
I have the following bit of code that is timing out when I pass it a long running set of SQL statements. I'm using the Microsoft.SqlServer.Management.Smo library from SQL Server 2008.
Using cn As SqlConnection = GetConnection(_destinationCNS, True) Dim smoServer As New Microsoft.SqlServer.Management.Smo.Server(New ServerConnection(cn))
[Code]....
I'm having trouble figuring out where to declare that timeout duration. What object and property should I be setting the timeout duration for the statement execution, not the connection timeout. On the SQLCommand object there is a convenient CommandTimeout property but I'm not seeing anything like that here.
I am having a problem with a SQL server query giving a timeout error. I read about setting the timeout value of the command object but in my DAL, I do not see how to do that. Here is how I create the command object
Public Sub Init() If ConnString = "" Then Select Case ConnStringID
I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).
I am using VB 2010 on a Windows 7 Home Premium PC. I can't get my my smtp code to send an email out. It always comes back with the error:"The operation has timed out"I have both a Google Mail account and a Sky Mail account both of which use the same port but can't get either to work. I have checked my firewall and the smtp port 465 is allowed and I can see the process going through the firewall.I know the mail works fine as I am using Windows Live Mail which sends and receives no problem. The code I am using is below:
Private Sub btnAddAmount_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddAmount.Click Dim message As New MailMessage
I am having some problems in my app for the database timeout. Due to some network glitches the query takes more than 45 sec to return the resultset which has about 10,000 rows. Most of the time its fast upto 11-12 secs. My app is runs as a scheduled job in the background.The problem is I need to try three times if i get the timeout exception before writing the error to the error log or exiting. I know i can set the command timeout property to 60 seconds but still i want to try three times before exiting. I have written a method for that but I think there is some flaw in my method. For now i specifically set the timeout to be 5 seconds as i know well that it takes more than 25 seconds for this stored proc to run. I just want to get that timeout expired exception and write ways to handle it.
My problem is if after 2 times I set the connection timeout to 50 so my method goes and get the correct list but it again goes inside the methodname which i have called inside the catch statement and finally returns nothing. It looks like its getting into recursion or something but i am confused as to where i am wrong.[code]
Sometimes when my server is down or busy, I get an error saying "connection timeout" while connecting to MySQL. But with the error the program also crashes. My question is how can I prevent crashing, it would be better to show a msgbox when this happens. (visual basic 2010)here is a screenshot of the error
I use this, Dim connStr As String = "Database=mydatabase;" & _ "Data Source=datasrc;" & _
why I am getting this error from a simple stored procedure that I created in SQL Server 2008 R2. I am trying to obtain data and insert it into a temporary table. if it is a timeout issue, how can I increase the timeout length to 420 seconds. to my understanding the timeout is good for only 30 seconds.
this is the error in its entirety:
Server Error in '/WebSite9' Application.

When calling a stored procedure from vb.net is there a default SQL timeout time if no timeout is specified in the connection string?I am unsure if there is a CommandTimeout specified in the connection string but am going through all the possibilites.
Example if no results after 30 seconds (or more) throw:
`System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.`SQL Profiler says that the script runs and ends in 30 seconds when the program timesout..Tthe script runs without error in about 1 minute 45 seconds by itself in SQL server.
I am trying to create a grid view in visual studio by connecting to a server and using a stored procedure. I am getting a time out error when I test it out. Can someone advise me as to what I can do? The query itself takes about 7 minutes to complete. The data is stored in a table. What can I do to extend the timeout?[code]...
"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." why i am getting this error message in the loop for the first row its works perfect but when it goes next in the loop and then it call again the function chkexist it gives the massege same error on call the nxtno function
