Forms :: Pause A Program Without Sleeping
Apr 12, 2010
The problem that I'm encountering right now is that I can't seem to get my program to wait for a couple seconds for another application to load before it starts to check if it's open. Here's what I've got (feel free to tell me its a terrible way of writing!):
Private Sub Running_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
Main.Enabled = False
[Code]...
So if I don't have the sleep function then oasicer hasn't loaded and it says it's finished straight away, but if I call a 5s sleep then it crashes, and not for just 5 sec. Is there a replacement for this line? Something that would just delay going to the while loop?

I am trying to make a start and pause button (and hence continue) to start, pause, and continue my program. The start button works but the pause button does not. Can someone look at my code and see what the pause button needs to do to pause the program? I am using VB 2005. Here is my code.

I have a StopWatch running, I convert the milliseconds to the following format. 00:00:00 i.e HH:MM:SS which is a label.
I can pause the the stopwatch and resume but I dont seem to be able to edit the stopwatchs time. So lets say my time says 00:00:02 , i now want to pause the program which I can, but also change the stopwatch time to 00:00:10 and resume counting.

My problem is that I have a textbox that is filled with a line of data from an attached barcode scanner. I want to make it so when something is scanned into this box, another function is triggered (it clears the textbox and commits the data to a CSV file, so the user can scan another barcode). I was using a .TextChanged function so that when the text was changed in this textbox, it would commit it then, however the problem with this approach is that if the serial number is 77G8DS, then it will commit 7,7,G,8,D and S individually, instead of an entire string.

1) Why the pause button and also the pause command does not exist in VB 2010 Express?
2) I have some solutions under 2010. In 2 or 3, while debugging, I can change instructions without restarting the application. In others, I cannot change anything (Is like readonly), Looking in 'My Applications', Tab 'Debug', Option 'Configuration' I can choose several Options. In the applications I can debug, the default is 'Active (Debug)'; in the others is 'Active (Release)'. If I change the options, the word 'Active' remains attached to the original option.

I would like for my program to pause for about 3-5 seconds and then close/exit after pausing. I've used the my.application.doevents() and threading.thead.sleep as well, which may work, but when I add close() after the pause it just closes.

I am not sure how to make my program pause in the middle of execution, waiting for a certain period of time to pass BEFORE the next lines execute. I have already used System.Threading.Thread.Sleep(int) but this pauses the waits but still executes the subsequent code. If I were to:Private Sub Hello()System.Threading.Thread.Sleep(int)MessageBox.Show("Hello")End Sub* Time in milliseconds.This would NOT stop the execution of the MessageBox for int seconds, the program continues to run???How would I pause the code execution where I want, and for the time I want?

I'm tryng to figure out a way how I can stop my code from running while I wait for input from a device.Networked device that sends data to .net app.I now wish to prompt the user to answer a 'Continue' questoion and select either 'Yes' or 'No' on the device. This is transmitted to program over netstream.I want the code to pause though while waiting for an answer as different routines are run dependent on the answer.

Is there a command or couple of code lines that will pause the running program for one or two seconds?
I have a program that checks the system time every 250milliseconds and I need to skip checking it three times the first time it comes back with ":00" seconds from the system clock.
Or another option would be to reset the timer to 1000 and then back to 250...

how to tell a program to wait or pause without using a timer control.
I did a bit of Lua scripting a few years back and the function was: Wait(5) or however long you needed the program to pause.

I have an application for PDAs with a long running process, and I'm getting the problem that the PDA is going to sleep before the process has completed.
I haven't got any control over the power settings on the PDA, does anyone know a good way for my application to stop the PDA from going to sleep?

I have a VB .Net service, which uses System.Threading instead of a timer to basically do what a timer should do. My problem is stopping the service while the thread is in its sleep state. See the code below:
Imports System.Threading
Public Class AService
Private stopping As Boolean[code].....
If say 1 minutes after the service starts, it can not be stopped until its 15 minute interval ticks and the thread wakes. Is there any way to catch the signal that the service is attempting to stop, and interrupt the thread?

Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

I'm simulating some threading in a Windows Service, and the Thread.Start routine for each of my threads points directly to the following:
Private WithEvents CheckForOrdersTimer As System.Threading.Timer
Private Sub timerCheckForContracts_Tick(ByVal stateInfo As Object)
' Ticks every 5 seconds, then spawns threads until we're at our max
Do
[code]....
the threads aren't even doing anything yet, but with more than two threads running at the same time, my processor (Core 2 Duo 2.4 w/ 4GB) gets pegged and Windows gets really sluggish. According to what I've read, Thread.Sleep shouldn't be consuming any resources at all while it waits, but it may as well be running in a tight timing loop.
EDIT: Per the requests, I've expanded the amount of code I'm using. I was initially doing some database work before spawning each thread, but I've removed it and the processor maximization still occurs with just the code here (and, of course, the OnStart method for the Windows Service.

I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.

i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.

I would like my forms to open as part of a "bigger" program, where there is a screen that fills the monitor and inside this screen is my form, centered. When a new form is opened, only the new form will be displayed...it will not be form on top of form.It would look similar to the screen in the following link, except the form inside the bigger screen would not have the minimize, maximize, or close buttons.I am just wondering if there is a property in VB.NET forms that will allow this to happen.

Microsoft's System.io.file.exists and System.io.directory.exists can take FOREVER, especially if you're in a situation, where you've unplugged from the network and you're looking in a share.
So, to get around this, I've created a thread that times out after 3 seconds. Returning false, if the calls above haven't yet returned. To do this, my main thread passes its instance to the new thread and immediately calls:
Thread.Sleep(TimeOutInSeconds * 1000) ' Where TimeOUtInSeconds = 3
The new thread then goes and checks for the file / folder using the System.io.file.exists / System.io.directory.exists functions.
Regardless of the result, then it uses the main thread's reference to call Thread.Interrupt().
My main thread doesn't get interrupted. It stays there for the full 3 seconds. If I were to change that to 3 minutes ( and I have ), it'll sleep for 3 minutes.

I've been trying to figure out how to pause a process. It seems I need to use 2 different APIs: SuspendThread and OpenThread.I found some C# code at this link that was working for them.After I translated the code to VB, I get nothing when I run the code. I debugged the app and put a watch on the function.The following is what I got from the watch: Name 'SelectedItems' is not declared.[code]In order to work with the selected process, I'm parsing the Process ID. I then use that PID to get that process and then work with it.I sue this type of code often in my project and it works just fine, which is why I am confused that I'm getting that message from the watch.
