VS 2008 Cannot Get Commandtimeout Or Connecttimeout To Fire Timeout Exception
Jun 10, 2009
Both of these properties have a default value of 30 seconds but I am setting them to something much shorter (8) and my application does not seem to recognize the timeout. Even if I allow the default value of 30 seconds to elapse I still am waiting on the timeout. I am trying to use the connecttimeout to notify my client application that the remote sql server is not available before I try and execute a sql transaction.
I am not sure why this is not working though, the sqlexception for timing out has worked for me before and all I did was set a non-default property. The only change here is that this is a MDI type of project, which shouldn't matter.

I'm not sure if this is a VB.NET error or SQL Server. But I get the above error with following stack trace:

or the server is not responding.]

Our production database as grown to a size where several of our longer running stored procedures are taking more than the default 30 seconds to complete. I've programatically set some of the CommandTimeouts on the command objects but the calls to the store procedures still appear to be timing out after 30 seconds.
Here's what I did:
In web.config set this property
add key="CommandTimeOut" value="180"
Added this to the top of my class that needs the timeout set:
Dim COMMAND_TIMEOUT As Integer = ConfigurationManager.AppSettings("CommandTimeOut")
After creating the command object set the timeout property on the object.
cmd.CommandTimeout = COMMAND_TIMEOUT
Unfortunately my stored procedures still seem to be timing out when they take longer than 30 seconds to execute.

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:

I have a routine that will connect to a tcp server and then disconnect which works perfect. It checks the connection to another program on another pc which is what I need. But if the computer is not on or the ip address is not valid, it takes a bit for it to time out and continue on.
how to add a timeout of 2 seconds to the following code?
Private Function CheckServer(ByVal IP2 As String, ByVal Port2 As Integer) As Boolean
CheckServer = False

I have a Windows Service that is behaving strangely on Windows 2003 systems (works fine on XP, Win7). If the service is started manually within the OS, then everything is fine. However, if the system is rebooted (with the service set to Automatic startup), then an "At least one service or driver failed during system startup" dialog is generated once the boot completes. If I check the event log, there is an event 7022 with the following text:

Sometimes my MySQL-commands hangs forever without throwing any exception. I've tried setting both command- and connection timeout for my connector, but it still hangs sometimes.Does it exist some kind of timeout block? Like, if the command hasn't been executed within X seconds, then continue.

I am not sure how much work there is to inheriting from the web client class.
Currently I am using it in my project. And I can't change to anything else. The customer would like to have a timeout after a certain period of time. The web client doesn't have this.
So rather than re-invent the wheel, I am thinking of inheriting from the web client and adding this property.

I caused the VB.NET2008 IDE to do something extremely odd and unintentional with some code I was writing. As some of you know, I mostly write programs for industrial equipment. On one of our products, I needed to make certain forms automatically close after a timeout period. To do this, I began programming a usercontrol with a Timer on it (interval = 1000) and a ProgressBar. Timer.Enabled was set to the Enabled event so I could toggle it. When the control counted to it's timeout period, it would call Me.ParentForm.Close
So I build my project, and drop it on a form in the IDE and I see it begins counting! Huh... I had no idea timers were active in the IDE. I wonder what happens when it hit's it's trigger? I figure probably nothing since Me.ParentForm was actually the designer. When it triggered, the whole IDE crashes without save. I tried it twice now. Here's my

I have a simple program. It has a "Start" and an "Exit" button. When the "START" button is hit, I change the text on the exit button to read "STOP PROCESSING". Then I go into my processing loop. When the "STOP PROCESSING" button is clicked the first time, the program simply ignores it. When I click it the SECOND time, it gets control. I know this because I put a breakpoint in at the start of the subroutine.What could I possibly be doing to quash the firing the first time?

I need to fire an event when the mouse enters a panel with the mouse button already down. It seems the standard mouse enter, mouse move, etc events don't fire when the mouse is already down. With test code i'm using, all of the events fire when the mouse button is up, none fire when the mouse button is down.
edit...here is my test code..
vb
Public Class Form1
Private Sub Panel1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown
Debug.Print("MouseDown")

I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]

It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

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.

I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...
