I know there is always better ways of doing things. Normally when you create a thread and I want it to pause/sleep for a set amount of time I use the <Object>.Sleep(1000) but this is frowned upon in .Net2+.

Currently I'm using System.Threading.Thread.Sleep(5000) to let my app pause/sleep for some time. This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this. I also tried using a timer but that didn't work out to well for me..
View 5 RepliesI'm looking for a way to pause my application while in a loop without affecting the users ability to control the application, the sleep thread method makes it seem that the app is frozen.
View 2 RepliesI have a frm_Main, which starts a thread. The thread then goes and calls a module, which has a thread.sleep() in it. This causes the mouse to freeze up while it sleeps, despite being called by the child thread. I thought this would have be on the thread time-slice? However it is causing my form to freeze for the sleep duration.

i got inside
WebBrowser1_DocumentCompleted sub
the code below
WebBrowser1.Document.GetElementById("form").InvokeMember("click")
Call ProcessNextLine()
when it clicks this button it should load another page(Like log in)
Call ProcessNextLine()
takes next line from txt file (It's url) + navigate
but I want it to wait let the page load before calling "Call ProcessNextLine()" I tried System.Threading.Thread.Sleep not working?

View 2 RepliesThe coding that I have a problem with might make people think that I am creating some malware. So the project I am doing is associated with iTunes. iTunes allows people to have one library. There is another way, but it is very confusing to some people, and very unreliable. So my project is that I will allow people to have multiple iTunes libraries on one computer. So the problem is this. In order to have an option to choose your library, I gotta make sure that iTunes is not running.
So this is the script:
Private Sub CheckAndCloseiTunes()
retry:
'Custom class that includes the function to safely close iTunes
Dim Processes As Process() = Process.GetProcessesByName("iTunes")

So when I use the Threading.Thread.Sleep(2000) code, the form becomes unresponsive.
I've been trying to use "System.Threading.Thread.Sleep(15)" as the delay code but if freeze the form. I used this "Location.Refresh()" where location is the name of the form, but it didn't give me what I need. This code is going to work on a ProgressBar while typing and the value of the progress bar change while typing. The progress bar jumps to the new value and I want it to move. So I thought about puting it in a "For ... Loop" but the whole form freezes.

okay this may be a simple answer so I apologize if it is. What I'm trying to do is when button1 is clicked for a text box to display text. Then when that same button is clicked again, that text box will display different text. Then so fourth for about another 4 times. Now I know putting this all together will create one big execution, which I don't want. I just want the application to wait until the button is clicked again to display different text.
View 8 RepliesI have a VB Windows App created using VS2K10. It produces pdf files from SQL data. The SQL data is refreshed every 10 minutes pulling from a DB2 (ERP) system via a Linked Server by a SQL DTS package being run by SQL Job Agent (SQL 2005). Because of OLEDB and security issues, the data download can only be performed by a specific Windows 2003 server. (It takes from 2-3.5 minutes to download the necessary data.)
Now, if the process of creating and printing the PDF files takes longer than 6 minutes then it's still running while the next data download is starting, the result of which is that several PDF files are created blank or absent any data. I tried to execute the DTS package on demand instead of on a timer, but cannot get past the OLEDB quirks related to our iSeries (IBM server) DB2 database system. The only answer seems to be to have the client application pause at a specific time interval and resume after @ 4 minutes, but I haven't a clue as to how to do that. Before you ask, using ODBC to pull specific data from the DB2 system directly into the client is too slow to be a viable option.
I have a problem with my application "getting ahead of itself" what the problem stems from is i am manipulating a file and then using the manipulated file further along in the program, the trouble is the program is getting to the second step before the file manipulation is complete so i receive a file not found exception. The program that is doing the manipulation has an OnEnd sub routine and i have been looking at event handlers to try and figure out how i can hold up the application until the On End routine is fired. But i have been trying this to no avail, is there an example i can have that waits for an event to be fired?

I would like some information on pausing my application until a file with a certain extension has been created. What hapens is, my application creates an input file that is sent to an external app that returns a file with a different file extension. In my application i then extract data from this new file.I was thinking i could use a timer to "hold up" my app, but then i started reading about event handlers and catchers. What i have tried is using an If FileExists loop but i get a file not found exception. How should i use the file create event? By looking in the folder and "waiting" for the file to be created?

View 1 RepliesI'm making... well, it's sort of like a game in VB.net (using VS2008, if it matters). Being sort of like a game, it's dependent on timing, but it also has a large area (have to scroll the window on pretty much any resolution).The problem I'm having is that whenever I scroll the window (or move any of the smaller, additional windows) the program pauses what it's doing, and doesn't start again until I stop scrolling (or moving windows, or whatever).So is there any way to stop it pausing when you scroll or move windows?
View 1 Repliesi 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.

I am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.

what I want is when i hits certain value, like let's just say i is divisible by 365, then the 'while' looping will stop, and a message box saying "target reached" appear. then after I click button1, the looping will resume until it reaches the next number divisible by 365, and so on.
1. Just looking for some general help on how to auto update my application via a file location path (e.g. I have a HTML file containing the current file version and the .exe file to download)
What I need is to read in the HTML file version - DONE Check file version vs HTML file stream input - DONE Replace current .exe file with new .exe file - HAVING ISSUES WITH THIS
I know I have to close the application and then replace the old exe file with the new exe file then restart the application but looking for the best/safest way this can be done
