I am using VB.Net 2008. I created an application that I want to be able to run stand-alone or as a service. This works fine. I used the "Service" project in VB to create the service. However, when I launch the application as a service, it takes a huge amount of CPU as compared to when I launch it standalone. The stand-alone version and Service version run the same code. The statistics from Task Manager are:
Metric Stand-Alone Service
CPU Time 0:00:34 0:03:01
Mem Usage 26,244 32,952
[Code]....
As you can see the only metric really out of sync is the CPU time.
We are currently developing a WPF/Entity-Framework based application.One of our requirements was to allow the user option to select which environment(testing, training, or production) they will connect to when logging in.Each connection option points to its own database.In order to do this we are creating new EF contexts in the following way:[code]We have made sure that all new contexts are being disposed of once its job is completed.The problem is this: when the users are using the application we are seeing hundreds of SQL Server processes in SQL Server's activity monitor. Some individual users have upwards of 30+ processes associated when using the app. Once the user shuts down the app the associated processes all disappear - but while the app is running these processes seem to stick around.
I have written my first service that checks the status of servers. I have used the statement System.Threading.Thread.Sleep(86400000), so that the service will run, then sleep for 24hrs before running again.
My problem is i want the service to run at 7am every morning, when i install and start the service it will run from the time i start it. I dont have access to required computer at 7am.
Is there a way of setting the service to run at 7am on the first run? Was thinking a Loop, or timer but dont want to be eating resources up while it is not necessary.
Does anybody know why hitting web services the first time takes much longer? I am not sure if this is per user, or per the whole application, meaning that if one user is hitting a web service, will another user hitting the web site also have to wait a while? I am not sure what is happening to rev up the web service.
I have a windows service that utilizes an infinite loop and thread.sleep. The sleep time for the thread is 10 seconds.When the service is initially started AND has work to do (data exist in SQL), it immediately does it's processes. It continues to be responsive and process tasks every 10 seconds as long as it has work to do. If no data is present in SQL for an extended period (i.e. 15-20 minutes) then the service starts responding very slowly. It will eventually pick the data up and process it, but it takes more like 10 minutes instead of 10 seconds.
So I have a .NET web service running and when i debug locally and run the service local to my machine a request takes ~4s. However when i push the project to my web server, the exact same request now takes ~1m. I feel as if the request should only take ~5s. I am not sure what I have set wrong. Here are my fiddler results:
i have created a WebService. and my webserver is in Canada. and i am accessing this service from India.Now problem is that i m not able to get the current time of that system in india.wht i hv written in Webservice is Now.Date.and it is not returning the currnet date of system where my webservice is configured.Please tell me how can i get the current date and time of that system.
I have an interesting issue that a client reported It turns out that the desktop application they are using is changing the times returned by the web service to their local time so it looks like the data is off. We're in UTC-5 while they're in UTC-8 so 8:00 AM is returned to the GUI as 5:00 AM which is causing confusion. I've done this riddiculousness to get around it for now:
Code: Dim intOffset As Integer = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now).Hours 'Substract 1 if we're in daylight savings mode
How can we schedule a windows service to run at specific time ( lets say every day morning at 6:00 AM )
For this i had a timer thread to sleep for 24 hours like below and start the service exactly at 6:00 AM ( but the requirement is.... no matter when the service starts, but it should run at 6:00 AM .... So how to do this )
Bottom Line : How to schedule Windows Service to run at specific time ?
I have written onw windows service..in that i have logic that is some part of code need to execute on certain time.. my service is running in every one min..
[code]...
But iam facing prob that it is considering seconds while running so can not compare above time..
I have a per-call WCF service that serves a number of clients. I'm looking to speed up the services by running some background processes so they don't block or slow down the main function of the services.
One example is that the main function needs to return a set of data, while the background thread needs to record some statistics based on the parameter(s).
Code:
Public Function GetAccountDetails(id As Integer) As AccountDetails Dim retVal As New AccountDetails Dim a As New Accounts
[Code]....
If I use this background thread to record the statistic it doesn't block the main thread from returning the data to the client.
It's been working well in test scenarios, but my question is, are there any dangers with leaving this thread to execute without Joining it before returning the data to the client? Could there potentially be any loss of statistic data? Could there be potential memory problems on the server side?
i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
I have a VB2008 application which can control a windows service i.e. start, stop, pause etc. This runs ok on a Windows XP machine but not on a Win 7 machine (message is - Service error cannot open <service name> service on computer '.') ( if I stop the UAC then it runs ok ). It seems to be a rights issue,
I'm writing a windows service (MacTimeFix.exe) to fix the Windows time on a Macintosh (it's like this: i live in Moscow (GMT+03:00), and Mac OS thinks that the system time is GMT+00:00 and adds 03:00 to it< and Windows thinks that system time is the local time).I need to execute my code when my VB app is closed. (it happens with the shutdown of Windows) The form is invisible (hidden), and the user mustn't click anything except windws shutdown button. It is a service. When i write a Form1_FormClosing sub, it works only on Alt+F4 or CloseButton and doesn't work when the app is stopped from Windows Task Manager or whatever also.I need a way to execute sub when app is closed with taskkill (without /force) or a way to execute a several app on Winshutdown.
Here is my code:
Public Class Form1 Dim SystemMary As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load SystemMary = Mid(TimeString, 1, 2)
I just want to create an service which will on start read my XML file .It gets the number of parameters connected to PC. I just want to know that is it possible to create the timers at run time in my service and the timers should start at the same time but will having different time span to exicute means one timer will start after every one minute while another after 2 or 3 or whatever i set.
I got this warning that I don't know what it means.Warning1 The service System.ComponentModel.Design.IInheritanceService already exists in the service container.Parameter name: serviceType00
I am trying to communicate with a Windows service on a remote machine on the network but i keep getting an exception saying the following: "System.InvalidOperationException: Cannot open Service Control Manager on computer 'machine001'. This operation might require other priviledges. ---> System.ComponentModel.Win32Exception: Access is denied.
Is it possible to have a dotnet windows service which monitor other services and upon stop of any service, the monitoring service would be able to start the stopped service.
This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
i was trying to make my service act dynamically... i have set time for my service about for 2 min ,if suppose it was doin huge amount of work means it will exceeds that 2 min time limit then we need to check the service condition if work is pending means we need to run that instance until upto finish.
public static void StartService(string serviceName, int timeoutMilliseconds) { ServiceController service = new ServiceController(serviceName);[code]............
In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
I had a problem getting a VB.NET web service client to receive the response object from a Java web service.In the process of posting this question someone from another department volunteered some code written for a similar situation.I couldn't find this anywhere on the net so I'm completing my question to help others out.[code]The web service is Apache CXF with some Spring elements mixed in.
I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?
how to deploy a service made in VB.net. Most of the websites just say use installutil.exe this is fine while your testing your service on your local machine whit vs2010 on it. I am in the final stage now of my service like 99% is done and my last % is how to get my service installed on the server i need it on. I can't publish because this wont work with a VB.net Service Project. So all i want is a clean and easy Tutorial or Someone who can explain me how to do this without the need to install VS2010 on the server to get install-util.
We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
