Time Out Expired Error While Executing A StoreProc That Retrieves 7000+ Datas?
Oct 19, 2011
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 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 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.

There are two location one main form and other is communication class which use comport to send command.Everything is good in VB6 but same code fails in vb.net actually program behavior is really different.in vb6 one function execute at a time but in vb.net it execute two function at a timeeg. In form there is function to write command over comport once command is posted one event is raised by serial port in this function byte array is formed and the statement immediate next to raise_event use this array to show on formbut when event is raised control is toggle between first function and event function it execute one statement from second(COMMUNICATION CLASS) function and one statement from f

I'd like to learn how I can add a bunch of strings into the AutoCompleteCustomSource property of a TextBox. Actually that doesn't seem to be possible.. What I actually want to do is to make the textbox suggest and append 7000 strings. I can do suggest and append stuff already but AutoCompleteCustomSource can contain a limited number of strings, so I have to find another way to add my strings.

I've created a page that makes several calls to different rss feeds based on the keywords I pass to the page. The problem is that each call takes .5 - 2 seconds to get a response and display the results. If I multiply the number of keywords by the time I end up with a very slow loading page. Is there a way to execute all of the calls at one time?

I'm making an app using wpf and vb.net in vb2010 express and having a problem. I have a timer that execute a backgroundworker every minute:
Private Sub timer_Tick() Handles timer.Tick
If Not bworker.IsBusy Then
bworker.RunWorkerAsync()
End If
End Sub
The backgroundworker is working with xmlelement and xmldataprovider:
Private Sub bworker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bworker.DoWork
Dim source As XmlDataProvider = Application.Current.Resources("r1")
Dim sometext As String = "something"
Dim elemento As XmlElement = source.Document.CreateElement("elemento")
elemento.InnerText = sometext
e.Result = elemento
End Sub
Then I'm using e.Result on RunWorkerComplete to add the XmlElement to source. It works perfect the first time I execute the backgroundworker, but when the timer calls it the second time it throws a InvalidOperationException in the line "elemento.InnerText = sometext" why is that and how can I solve it?

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 having a problem with my try catch block runs in the error "dastabase is not available". My problem is the try catch runs and catches the error, but it will not redirect to my error page. The code continues to execute the other subs. I have tried adding: exit, return, response.end. None of them worked.

We have several programs that run during off hours and I want to write a program to monitor them. I have defined a list of priority programs and have written code to verify that they are running using 'Dim instance As Process'. The problem is that I can't figure out how to determine if the program has a pop-up error window like "unhandled exception" or similar window. The instance.responding still shows 'true'. How can I identify a process that is executing but has an error?

I have published application before and they all (3 setup files) work fine. The problem is I don't know anymore how I exactly did it. Now I am trying to publish another form which has a connection to my sql database. The publishing goes fine: publishing folder is: C:Movie-databaseApplication 4 and installation folder is the same, and I therefore leave it empty. Application is available only online. But when I execute the published setup.exe I get two windows with no info about the error: see attachment.

I have a tabcontrol with a number of tab pages each of which contains a DataGridView control. I populate each DataGirdView form a local SQL Server. The method which does this works fine. The problem I'm having is I want to use the same method to populate each DataGridView control. I created a private member variable called mDataGridView as a DataGridView and use the TabControl SelectedTab property to determine which tab page the user has selected. I then try the following
[code]...
I then use mDataGridView in my method which retrieves data from the SQL database. Although the compiler dosn't gag at this it doesn't work. Am I right in thinking that mDataGridView references dgvQuoteTemplate?

Two questions:
1) I have a stored procedure that retrieves item information from a SQL Express database. Should I attempt to do the rounding the stored proc or client side in the app?
2) My rounding needs to be custom. I have a figure that goes down to the 4 place meaing x.0000 if the 3rd digit is 4 or more then I would round up to the nearest cent x.00 if it is 3 and below I would round down. I have looked at the math functions in vb.net and I dont see right out the gate how to accomplish this.
So my question is should rounding be done in SQL or client side and if it is client side do any of you have pointers on how to slice and dice this?
