Create A Pause In Program?
Jun 19, 2009In VB.net, is it possible to create a pause in a while loop, wait for user input (for example, hit the STOP button, if desired), and if no input within say... a second, continue on?[code]...

View 1 RepliesI 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've asked this question before but am reposing it because I am still having problems. The snippit of code that I have problems with is this:

The problem with the code is that I am never able to press Button2. The loop continues and even with an application.doevents, I am unable to press button2 to make bEnd become true and pause the code. Does anyone have an idea of what I could use so that Button2 could be pressed during this event. The idea of multi-threading was tossed around before but I would need some good references to get an idea of how to do it.
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.
View 1 RepliesI am fairly new to programming and vb.net and I am working on a small project but in the project i need a message box (2 different occasions) where the buttons, instead of Yes No say Pause and GO. The video [URL] told me to make a new form (dialogue) and then in my main form add a public sub.
Here is the sub I have:
Public Sub injectmessage(ByVal ingmessage As String)
Dim topmessage As New Message
Dialog1.Label1.Text = ingmessage
Dialog1.ShowDialog()
End Sub
All that does is puts the message on the messagebox.
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.

How do I prevent the program from opening 3 windows at a time if there are 3 items in the listbox..how do i tell it to not to start the process when the current process isn't finished yet...like 1 window at a time...
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.
View 8 RepliesThe 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

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 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?

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.

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...

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.
How would I pause an external program (exe), wait 10 minutes then unpause it using VB.NET
View 2 RepliesOut 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.)
View 3 RepliesI 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.

View 20 RepliesI am very very new to VB.NET and would like to ask a simple question. I want to create a vb.net program and allow visitors to a website to download this program. However, I prefer not to have visitors download a zip folder. I would like to have a program that just gives a prompt to save in a selected folder, once the saved file is selected it prompts the person to download, and then when finished prompts the person to run the program. The reason is twofold:
1. I don't like the extra step involved with unzipping the file. and 2. I don't like the visitors having to look for the "main" file program within the new downloaded folder. So is there any way to have just one file for others to download without having it in a zip folder?
I'm trying to create a program that installs required .dll's for a program due to a clean install..What I need to do is Get a value in the registry and use it for the program files path.. but I've noticed some pc's don't have the same configuration because of the version the user is using. Anyway This is what I have so far:[code].....
What I'm trying to do is find a registry key called "SoftInstallPath", if found I need the end of the path to goto the new directory(new_dll) not the old one (dll).. and if "SoftInstallPath" cannot be found.. I need it to find "ProgInstallPath" and use it instead and do the same thing.By the way I'm using Visual Studio Professional 2008 on a Vista x86 machine.Also error I keep getting is: Warning 10 Function 'FixPath' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.

View 7 Replieshow to put a pause into a script I am running and have it repeat itself :-)
View 1 RepliesI'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.
