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..
We have a windows service running under a network account that calls and runs an ActiveX exe. The exe is running under the local system account, not the network account of the service.
View 1 RepliesI 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'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 have a windows service written in .net framework 2.0. This service installs and runs perfectly fine on both XP and windows server 2003.We have a new 2008 box that we are migrating over to, so need to get this windows service up and running.When i try to 'start' the windows service on the 2008 machine, i get "Windows could not start the <service> service on local computer. Error 1053: The service did not respond to the start or control request in a timely fashion."I have searched everywhere looking for an answer, and all I could find was a fix attributed to .net framework 1.1 for this same error. That; however, is not applicable here, as the service was written in 2.0.
View 3 RepliesI have a console application that is ready to be used as a windows service, I have been looking around for a couple of hours and tried many of the tutorials out there but none of them worked with me.
The closest one was: [URL] but it didn't go into the process of doing it. I converted that code to VB.NET but then I don't know where to go from there. I have the Module1.vb which runs my console application all ready to be used.
show me a way to use my console application as a service, I tried using the InstallUtil feature but my app never showed under "services".

Right now I have it limited to only accept requests from 1 specific IP to that port and all the other ones get rejected (using the windows firewall), is there a way to implement an authentication or anything else so I can allow it to be accessed from any IP worldwide yet have it secured?

View 2 RepliesI 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.

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.

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.

View 4 RepliesIn 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?

View 1 RepliesWhen you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?
I tried Console.WriteLine(Cstr(DateTime.Now)) and it shows the time down to the seconds, ie, "5/26/2009 5:17:02 PM" But, is there an option to show the current time more detailed than seconds, ie, "5/26/2009 5:17:02.xxx PM"
View 2 RepliesBasically, my app has the main form and a windows form "splash". Let me explain, this "Splash" is a WINDOWS FORM, not a splash form; its just named splash because I want to use it for that reason.In my project settings, my main form is my startup, and the splash form is my splash. This splash form has been coded on a timer for 10 seconds, but when I set the splash form as the splash setting, the form shows up for 1 second and goes to the main form.What I need is to edit the splash setting time from 1 second to x# seconds (preferebly 10)

View 1 RepliesSearching about kernel32.dll and battery functions in it, I came across some interesting
Public BatteryLifeTime As System.UInt32
The full declaration is:
Private Declare Auto Function GetSystemPowerStatus Lib "kernel32.dll" ( _
ByRef lpSystemPowerStatus As SYSTEM_POWER_STATUS) _
As Integer
Private Structure SYSTEM_POWER_STATUS
Public BatteryLifeTime As System.UInt32
What I don't understand is, what measurement do the "BatteryLifeTime As System.UInt32" is in? I mean, is the Battery life Time in seconds or hours.. Or something else, so how can I convert it to something I can use..
I am writing a program and have run into an issue. The program requires a conversion of time (e.g. hours,minutes,seconds) to a hexadecimal value of no more than 4 bytes (e.g. FFFF). I have no idea how this is done. Can anyone point me to a tutorial or give a quick explanation. Sample code would be great as well.
