Do Timers Cause Page Faults
Jul 9, 2009
I have the system tray icon changing pictures based off a timer..and when I check my page faults they go up on every tick ofthe timer.. so then I pull out the changing of the picture thinkingthat was it.. but still page faults increase..so just wondering if timers have issues ?this was a timer from VB6 ? is there a new timer I should use from.net.. delete the old and use a new control ? I have a couple sobefore I switch them all out.. figure I would find out first..

Am pretty new to web services and have been trying to implement Soap Faults. I used Apache Axis2 to generate webservice in the following manner.
[Code]
Now, I created a dynamic project using Eclipse and with the help of Axis2 plugin I created webservice for my "Webservice" class which generates wsdl file. I deployed the webcontent in the Tomcat folder and able to access the WSDL file in the .Net environment. I am able to pass array of objects (User[]) from .Net to Java and able to do my task. Now, I need to implement Soap Faults in Java which I am not sure how to implement.

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

Does anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.

All the code needs to be controled by seperate timers as the user may need to pause timer3 or timer4 at any one time. The problem I have is that after about 5 minutes the time and elapsed time are about three seconds ahead of the two count down timers.

I'm developing an application to learning purposes only. The application will check some proxies that are in a proxy list.
I did a For Each loop ( to run all the proxies in the listbox ). The problem is some proxies are slow to answer and I must do the application wait some seconds before get the next proxy.
I tired a sleep thread but I don't want the application to be unanswering. There's any chance to help me with the timers?
I tried all possible ways and searched a lot but my problem is each time the timer ticks, it make the full for each loop again instead waiting.

The thing is i have a Master page and a Content Page. I have a LoadComplete in Content Page and a PreRender in Master Page. The problem is one of my htmlcontrols on content page i change on the LoadComplete event server side of the content page. I also have some code for disabling controls on the Master Page PreRender event. For some reason all controls on the aspx side go through the Master Page prerender except the ones that i change on the LoadComplete side. How can i make sure the entire content page loads and then the Master Page PreRender event is called, making all the controls go through that event.

I am using vb 2008 I am trying to learn loops and timers but I have some problems. [Code] The problem with this is it does not wait it just sends 123 all at the same time. I tried using the other way the one that makes the program freeze for the amount of time I want it to wait, but I don't want the program to freeze I want to to move my mouse ext whilst its doing it. as for the loop this is as far as I got I cant really test it yet cos my program is typing 123 a million times a second and my pc doesn't like that so i need to fix the timers.

I created a timer in the main form - form1 which then updates some text in form2 each 100ms. Now When I click a button in form1, the timer stops. Why? Happens no matter if timers are on or off by default. I have to open/close form2 to make my status updates work again - that's where I run the timer on form load and stop the timer on form close.
Was doing it in windows 2010 express.
So this is what I have in form1:
Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'some stuff

I have a background application with a couple of System.Timers.Timer running in it. I also have a NotifyIcon that when double clicked brings up a windows form.
My problem is that sometimes my form gets displayed but then for whatever reason it seems like it's losing focus and becomes un-usable (it just sits there in the background).
So here comes the question now... Can the freeze be caused by the form loading (i.e. me double clicking my NotifyIcon) and the timer tick happening the same time?

I'm considering making an application that will perform various tests against servers on a local network - for example pinging them, checking hard drive space, checking the state of services, whether or not databases are available, etc etc. Very similar to Hostmonitor if anyone has ever used that - but my app will be free
These tests would have to be performed at specified intervals, but the problem is that there could be literally hundreds of tests and I'm not sure how well my app would cope with hundreds of timers running... especially if they are all configured to run every minute or two (they all need to run independently of each other).
Really I'm just wondering how you guys would design such a system.The best way I can think of is to have a separate timer associated with every test and then when a test's timer has elapsed use the ThreadPool to do the work that the test will perform. That way if loads of them happen to run at the same time then the ThreadPool will queue them rather than trying to run say 200 at once. I also think I would need to have some kind of staging for when the app first starts, so that every single test is not going to have the exact same time to run (well, every test that has the same interval configured), but that shouldn't be too much of an issue.I guess it would be a good idea to try and use some sort of grouping so that more than one test can use the same timer - like if 20 tests were set to run with a 5 minute interval then I could use one timer and run all of the tests when that one timer fires.

I want to expand it a little bit and add a second timer that runs parallel to the first timer, but is not affected in any way shape or form by the first timer.
Ive tried nesting the second loop in the first loop but the second loop takes 3 seconds to complete (I use thread.sleep(3000)), so I found that it froze the first loop till the second loop finishes. I was reading about system threading (System.Timers.Timer) and it seems like that is the route I want to go.
I wrote this quick as an example:
[Code]...
I cant use the timer1 to set off the second round of events because of the thread.sleep. I was hoping that the code above puts the second thread to sleep while the windows.form.timer continues on ticking every 1000 ms
