All Of A Sudden - Sql Server Timeout
May 25, 2010
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'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.]

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 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();

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.

for some reasons suddenly all comboboxes within my project An exception (System.NullReferenceException) is thrown whenever I try to scroll down a DropDown or a DropDownList to the very end. This happens to all comboboxes with more items than the MaxDropDownItems property with a vertical scroll bar. No code is being executed at the moment the exception is thrown. The application is just waiting for the user to complete his entries.
This did not happen until today and I didn't change no code. There are lot of comboboxes within the project and I'm very amazed (actually frustrated) about the exception .

I have written some code (VB.net) which simply runs a backup on all required servers and databases in a loop. The code works perfectly, except for the first backup which Timeout's after 30 seconds (even with my Connect Timeout=0).
Everything is written manually for the dataconnection, the connection opens and timeouts on SQLComm.ExecuteNonQuery()
dbConnStr= Data Source='Server';Initial Catalog='Database';Integrated Security=False;User ID=sa;Connect Timeout=0;User Instance=False

I am using VB 2005 and need to trap a serial port timeout. I use a standard try/catch block, but if no characters arrive the code still hangs at the ReadByte call. Here is the code:
Try
SerialPort.ReadTimeout = 200
' read timeout of 200 mSecs
thisByte = SerialPort.ReadByte()

I have written a page with an iFrame that basically cycles through a series of internal pages on our server displaying daily activity for our company. The problem I think is that it sporadically loses its session and redirects back to the login screen to keep losing its session which is the default behavior for anyone on our site trying to access a webpage without being logged in.
I have set the session timeout to 4hrs, the iframe cycles through 6 pages anywhere from 10 seconds to 5 minutes on each, and I have even set the META refresh on the page to refresh every 3 hours. I don't understand what else could possibly stop this page from staying active.

In this situation, my application can connect to the MSSQL server in one of two ways; via a direct TCP/IP connection (WAN) (IP's filtered using RRAS in 2003 Server) or via a VPN connection. The application will first try to open the connection using the WAN connection string and if it can't, then it tries using the VPN connection string. My issue is, I set the connection timeout to 5 seconds for the first attempt but it's taking way longer than that to return an exception. The order in which I attempt to open the connection doesn't really matter. I have looked at the ConnectionTimeout property after changing the connection string and it does indeed show 5 seconds. It appears that the connection timeout value is being ignored.

I am looking for the VB.NET code of a very handy little *.bas file I used to use in Visual Basic 6. The file was called timeout.bas and it was the greatest module ever to me. I want to switch to start using VB.NET finally but this single file is holding me back. Trying to use .NET without it is like crippling me. [code]

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

I'm trying to use a socket to connect a TCP stream. The socket connects no problem if the endpoint has a valid IP associated to it. If I give it an invalid one, the Connect method will sit and block (I want it to) for 10-20 seconds before telling me the remote host timed out. Is there a timeout property I can set so I don't have to wait that long for the connect method? Or is there another way of doing it that does implement a timeout?

I'm using sqlbulkcopy to load data into a sql2008 database, and we're getting timeout errors loading larger tables. Some tables which were loading OK are failing since indexes have been added to them. The source data is a Informix datareader. I've tried setting large values in both the connection timeout and the sqlbulkcopy.bulkcopytimeout, but the timeout usually occurs within 60 seconds, well below the timeout values I've set (240 secs). I've tried setting the .bulcopytimeout property to zero but it makes no difference. Very occasionally a load will take place - the last large table to load took 7 minutes. I've reduced the batch size to 500.
The documentation on bulkcopytimeout that I have found does not describe what the property actually means - is it the maximum time to complete the entire copy or to complete one batch or what ?Here's some extracts from my error log - the first shows a successful large table load, follow by timeout failures.

I have this simple code to test that a DB is ready:
Function testlocalcon() As Boolean
Dim constr As String = _clconstr
Try
Using t As New SqlConnection()
constr = constr & " ; Connect Timeout=1"

I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored.

I have a vb10-form that makes connection with a SQL-db. The first time the SQL command is executed perfectly and the records are showed as they should. When I do a refresh (or automatic refresh after 1 min) I get: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding" The strange thing is that this only happens on one PC, all the other work.
