.net - Two Timers Running Simultaneously And Independently?
Oct 27, 2011
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
i was wondering how to make subs and functions run simultaneously. For example, if i make a box move from the top to the bottom with a sub called move(byval e as label)
which takes say 3 seconds to move from top to bottom and i have
move(lblfirst) thread.sleep(500) move(lblsecond)
how would i make it so that it moves 500 miliseconds after the first one start to move, not 500 milliseconds after the first one finishes?
I tried application.doevents with a looped sleep and raiseevnet, none is working.
I'm attempting to convert VB 5.0 source code to VB 2008. The converted code will then be slightly altered to facilitate its incorporation into a larger project that I'm developing in VB 2008. After using the conversion wizard (which is actually written for VB 6.0), I have 49 unresolved issues -- less than I expected. Much has changed since the days of my prowess as a programmer (Fortran in the 70's), so working my way through even as few as 49 issues will be a challenge, and will (no doubt) take me a while.
The UI for the VB 5.0 code I'm converting is a "virtual remote," with control buttons that (when clicked) trigger communication to a USB-connected device. With assistance, I've been able to develop my own "virtual remote," contained within my VB 2008 project. Eventually, I will "substitute" mine for the original. For now, though, I'm wanting to use MY "virtual remote" to trigger the original.
I have the executable for the VB 5.0 program, and can run it simultaneously with my "under-development" VB 2008 code. Problem is: I don't know how to cause a "click" on MY virtual remote to trigger a click on the original virtual remote (which is being "monitored" by the other program).
I'm creating a 2D RPG game, the character moves by pressing the keys A (left) and D (right), this activates a timer that increments the x.position of the character by 1 pixel in case you press D, or decrements if you press A. The movement of the main character is always perfect and smooth and this is how I want to do it, but when I add other character and I animate them using the same method, they dont have a smooth movement, but if I press A or D these characters regain a smooth movement, so, basicly, the second timer (which is always enabled) only increments a value smoothly if the 1st timer (not enabled) is activated.
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.
I want the timers to run like this:
Time Timer1 Timer2 0 X X 1 X 2 X 3 X 4 X 5 X X 6 X 7 X 8 X 9 X 10 X X

This assumes that I added a windows timer control as timer1

I have a MDI WinForms application that can perform several tasks. Each task is running as a backgroundWorker.What is the good approach to control the running threads:check whether the specific thread is running stop specific thread ?For example it shouldn't be possible to run the same task simultaneously.May be I need a separate class where I can store isTaskRunning variable?
I have two websites "WEBSITE 1" and "WEBSITE 2"...now i want that when someone logs in to "WEBSITE 1" he does not have to log in to "WEBSITE 2" and vice versa...ie when he/she logs in to any one of he websites and opens the other one simultaneously he/she does not have to login to the other one.For eg :- when you are logged in in gmail...you do not have to log in in youtube or orkut or google+
[code] 'The description for the state.getbuttons() is:'Public Function GetButtons() as Byte (is a array of buttons).'The high-order bit of the Byte is set if the corresponding button is down, 'and clear if the button is up or does not exist.This code is used to show if certain buttons of a GamePad/joystick are pressed using the DirectInput method (DirectX SDK).This code shows how many buttons are pressed simultaneously. So 00 for zero and 00 01 if two buttons are pressed. I would like to know what button exactly is pressed (some kind of unique code for each button). But I can't get it done.
1. Is there a way so show all the bits inside the state.getbuttons()? (maybe there is a unique combination for each button).
I have referred to the following question at: Using foreach loop to iterate through two lists. My question is this, with regards to the chosen answer: Can the o.DoSomething be a comparison? As in:
For Each a in ListA.Concat(ListB) If(a from ListA=a from ListB) Then Do Something here End If Next
I'm using VB.Net and would like to know how I can do what I have shown here. That would basically be to iterate through a joined list separately/independently.
ok im reposting this question cause i got some off track answers last time.I have 3 aspx pages - page1, login and page3. Now when i goto login page from page1, after i login and goto page3 i should be able to open a popup on that submit and the login should change to page3. but if i goto login page directly, the popup should not open and the login will goto page3 as normal design. how can i achieve this?

I have two form the parent form with the menu list and the child form. I want to show the two form simultaneously or the main menu first and then the child form.
I used different backgroundworkers to instantiate some 'heavy' forms thinking that it will reduce the time to instantiate them if I did them at once but it looks like I am wrong since it is still taking about 43 seconds to load all of them. Am I missing something or do you have a tip on how I can speed up their instantiation?
I wrote a function that returns the number in a particular field, my issue at the moment is how to update that field before i return the previous value i collected from the field. i am seeking any guidance available. Enclosed is the function i wrote.
Function GetTransactionNumber() As Int64 Try GConn.ConnectionString = GConnstr
how can i query 2 arrays simultaneously?for example:
dim string1() as string = {"a","b","c"} dim string2() as string = {"d","e","f"} dim string3() as string = ? 'linq query that selects all elements in string1 + all elements in string2
Not wanting to hijack 45minutes thread, I thought I might spawn a thread of my own based on his question.
PlausiblyDamp was kind enough to provide some generic code, which I have modified and attached.
I have made a few alterations mostly around removing random objects, as the game in question (Space Invaders) has a set amount of aliens and set starting positions.
As a start I have limited the UpdatedPostion to horizontal movement as the aliens only go side to side unless they hit an edge.[code]...
I am creating a GUI that monitors the entered application and if the application crashes the GUI starts the application back up. Problem is to run this application (WoW Private Server) I need 3 running applications. Is there a way to shell and wait 3 applications all at once. OR if i was to create a separate console application who's only job was to start the three applications at once how would I pass the application variable? Here is my program thus far: [URL]
I have an app that I query a database for IP information, then Ping the IP's and log the results to a database. This takes a long time (testing with 200 takes about 5 minutes as they are all sites across public internet) due to waiting for response from 1 ping before sending the next ping for the next site.
i want to add a picture of a field like a football field and on it a ball would roll (just like the football). i have loaded the field's picture in the picturebox , but m nt able to load the second picture i.e of the ball. how can i do this?
We are looking to design a security application that does the following on laptops:If the ethernet adapter is used (cable plugged in) disable/block all other network connections (wireless WIFI, mobile broadband (PPP), virtual VPN adapters etc)When ethernet adapter is not being used again, all connections allowed.We have looked in the WMI a lot but there are no good ways of doing this. Only disabling the network connection is not secure enough because most mobile broadband applications try to re-establish the connection. This should be an application that works on all laptop vendors without any user interaction (such as choosing interfaces etc..).
I'd like to allow the user to select up to an entire column of cells and type and/or paste a single value that would then change the value of all the selected cells in the DataGridView to the value that was typed or pasted. I understand this is probably two separate answers, but perhaps if there is a way to set the contents of the clipboard with the value typed, I was thinking it may work well to identify both things I want to do.
I need to play multiple files simultaneously at the moment i am trying to use mciSendString() API it plays the files listed in a listbox. But it is only playing the first one i assume it would play the next one after the first is finished... cbf waiting to see.
I have been using the My.Computer.Audio.Play method for sounds in my program for a very long time, but now I have reached a point where the program needs to be able to play more than one sound at a time. What is the best (and preferably simplest) way to do this?
I want to play multiple sounds simultaneously from My.Resources in Visual Basic 2010. I have tried:My.Computer.Audio.Play(My.Resources.SoundName, AudioPlayMode.Background)
I have also tried using multiple Windows Media Player controls, but that also didn't work.The first sound is cut off when the next sound plays.When searching around the internet I found people suggesting using 'DirectSound', but there are only tutorials for DirectSound in VB 6.0.
WebBrowser1.Navigate("javascript:OnClick(go(512,5))") WebBrowser1.Navigate("javascript:OnClick(go(513,5))") But this presses only on the second button ("WebBrowser1.Navigate("javascript:OnClick(go(513,5))")")
I made a favourites feature on a webbrowser I made, however it can only add favourites and not remove them. Even when I remove them from the Listbox using[code]...
