Console App Timer To Call Web Methods Every X Minutes?
Dec 22, 2010
I am coding in VB.Net, VS 2008. I wrote a console app that consumes 2 web methods from a web site application. I need to enhance this console app so that it launches the web methods continuously, perhaps every x minutes (during business hours), but never before the last invocation has terminated, whose duration may vary, depending on how many accounts there are to process.
Originally, I scheduled the application using Task Scheduler, but I think this doesn't prevent two invocations at the same time.
Although I have seen many posts on using timers, I haven't found exactly what I need.
So far I have:
Dim aTimer As New System.Timers.Timer()
AddHandler aTimer.Elapsed, AddressOf TriggerWebMethods
' Set the Interval to 10 minutes:
[Code]....
When should Timer.Elapsed be used vs. Timer.Tick? What is the difference between Timer.Enabled vs Timer.Start, and should I be selecting just one? I would like the 2nd web method to kick off when the first one is done.
Is it possible to configure the System.Timer to run say 30 minutes after every hour? I have searched google to figure this out but all it shows is how to set it where it goes off once an hour, if I launched the app at 2:45 then it would go off again at 3:45. I can forsee issues down the line with this approach where if it went off at a specified time it would not have that issue.
Normally i would use Scheduled Task for this however it doesn't give you the option for hourly just daily, perhaps i'm wrong about this.
I have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.
I have 4 textboxes Hours, Minutes,Seconds,Milliseconds. When textboxes values are set the count down begins. So far everything works except the milliseconds
Timer1.Tick Timer1.interval = 100 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Dim Vals3(3)
I im trying to set a time so that the user of my quiz has to do their 20 questions in 40 minutes. i actually have a few questions about the timer. How do you make it so that you canrun this same timer over everyform and then make it stop on the last form? is it possible for you to convert the timer so that instead of it running in milliseconds it runs in minutes?
I have an I/O device with 8 channels. I want to create a timer control for each channel with combo boxes for days, hours, minutes and radiobuttons for AM or PM. This is a crude (and not working) example of what I need:[code]
I will preface this by saying Im previously an asp developer and am learning oop programming/Vb.Net
Im working on a 3 tier architecture and trying to abstract my code as much as possible since I have a very large intranet to convert. In my business layer I am defining my classes with management methods. Below is an example of one of my classes.
My question: Is there a way for me to genericaly refer to the class type and object type so that I dont have to continualy refer to the class name/type "ServiceRequest" throughout the class. For example something like:
I have 4 rounding options: None, Standard, Up, Down If they choose None and the number is 108.7879, I just want to display 108.78 with no rounding. I know I probably can use Math.Ceil for Up and Math.Floor for Down, but I am not sure what to use for None or Standard.
I am trying to use an timer control in my console application Friend WithEvents XTIMER As System.Windows.Forms.Timer I am getting its all the properties.I have set the interval to 15000 ms.but even if i am setting the enabled state of the timer control to be true,the tick event is not firing
i am trying to understand how to keep my console app open even after it gathers data and sends it off. I am converting a GUI to the console app. It has a timer that fires the sub every 20 seconds. But it doesnt seem like it works in the console app since after it fires off the sub it closes the app without waiting.
There are no "non-public" or "static" methods in my code. All are public. What I'm trying to do is pass a FrameworkElement (more specifically a web browser control) that was created in one process over to another process for display and use. Also I'm not using (and would to avoid using) any of the framework 3.5 addin stuff.[code]
I'm a newbie and trying to develop my first program. The program is a console math quiz application. I want to add a timer to the code that tells the user the the amount of time it took for them to complete the quiz. I have no clue as to how I need to implement this.
When I call a different sub from the main sub in my console application, I have to type in the word twice for it to go to the sub. But I have noticed that it only does that when I have it to be recognized at the second instance (I think I used that right). What I mean by that is this.
Sub Main() if console.readline = "Test1" call _Exit_()
[Code].....
If I type Test1, it will call the _Exit_ no problem. But if I call _New_, I have to type it in twice.
I also tried putting them both into if statements instead of elseif.
I have also change the order of the calls, this is where it get interesting to me. If I were to change the call from "Test1" to _New_ ()(So, instead of calling _Exit_(), it will call _New_()) If I do this, then the _New_() will work no problem and I don't have to type it in twice, but I do for the _Exit_() now.
I have a .dll file (Interop.ACTMULTILib.dll) that I use to connect to a PLC. This .dll contains a sub called ReadDeviceBlock2(byval devicename as string, byval size as integer, byref data as short). When I call this method in my main it works fine, if I call it from another method that was called by main it works as well.However, it doesn't work when I call it from my Timer_Elapsed sub? I guess this has to do something with threads but I can't figure it out.
Module Main Private Timer As New System.Timers.Timer Private PLC As New ACTMULTILib.ActEasyIF Private DataSet As new DataSet[code].....
I have a console app that is supposed to async call a web service...i don't get any errors but the completed handler doesn't seem to complete correctly. I have a subroutine with a loop that is supposed to fire off say 6 seperate calls to another routine that calls the service. The completed event handler routine puts data into the database..If i put a thread.sleep under the call to the routine calling the web service. The completed event handler fires but only one record is put in the database instead of the hundreds expected and only that one webservice call appears to fire.I should mention that this works as expected when calling the sync method of the web service within a console app and the asyc calls work as expected from a windows forms app. I just need it to work async within a console app..
I am looking for formula that is accurate in converting Minutes to Decimal Minutes i.e 30 minutes is 50 Minutes in Decimals so 1.3 hours is 1.50 and not 1.5 i have used Minutes/60 but it is not accurate as some times i have to Multiply the result by 100 and some time 1000 to get correct results based on single digit Try 1/60, 10/60 99/60 or 100/60.What would be the most efficient and correct way to Convert the time into Minutes ?
Imagine that I have a System.Windows.Forms.Timer with 1000 ms interval. If I call Timer.Start() method and after 500 ms I call again Timer.Start() what happens? The second Start call will reset the interval or not? Are there any side effects?
It works, when I make getBar methods public, but I don't want to expose these unneccessarily. Why I can't call private shared methods from a public one in the same class is over my head. I'm using .net framework 4.0 in a web application.
public class CategoryRepository: RepositoryBase<Category>, ICategoryRepository { public CategoryRepository(IDatabaseFactory databaseFactory) : base(databaseFactory)
[Code]...
Does anyone has an idea what i should change to let it work and let my UserRepository use the methods in RepositoryBase while implementing the IUserRepository?
I am working with a vb program, but there is something strange on one of my .vb code pagewhen i put the "dot" afther the object name its dont show the methods availables for this objectbut on other vb code pages i can see it. but in this one no.for exmaplethis is a piece of code: Dim sb As New StringBuilder()
I am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?
I have an application that provides a countdown for 60 minutes and I'm currently using the win form timer and it updates some labels and a progressbar. Now I have to change this to be a countdown for 360 minutes. Will the win form timer be sufficient or should I implement a Timers.Timer instead?
