How To Have Keypress On Console Without Program Has To Wait
Jun 4, 2012
I built a console application with a loop at the end,[code]in the loop when the user press "q" on the keyboard, the program will go out of the loop, I've tried using Console.Read or Console.ReadKey which is not working because it waits for the user to press the keyboard,but I need the loop to keep running although the user is not pressing the keyboard so in the program the console will be like: AAAAAAAAAAAAAAAA,etc. until the user press "q" on the keyboard,

I want to have a one second pause after some code has run. During that pause, if a certain key is pressed, I want to do some action. Otherwise, I want the code to continue as normal. What would I use to replace the comments in the following code?
myTestCode()
' Wait one second and see if a given key was pressed.
' If specific key is pressed, then show messagebox (or whatever) asking user if we should cancel (whatever)
NextMethodToRun()
Yes, I know there are a number of ways, which is why I am looking for something that is fast and simple to use. I do not want a console window, some other form, etc. to appear. Just want to check if a key was pressed. The key (if pressed) should be pulled off the keyboard buffer.

I have a console application and i want to run some code but at the same time I want to have the ability at any given time to press CTRL + SHIFT + S to stop it,
Now I tried doing something basic like this which would stop if you press X at any given time:
Dim stTest as string
Do Until stTest = "X"
stTest = console.ReadLine
console.WriteLine("you didn't press X yet...")
The problem is that every time before it writes that line it will wait for the user input because i have "Console.ReadLine" on there, I don't want that to happen, I want it to keep going until a set of keys are pressed.

ok I have a program that controls another program.. but sometimes the other program is not running.. so I ask the question "do you want to run it up" so if they it takes like 15 seconds to come up.. so really I dont want to do much on my program while we wait for that other program to finally come up..
normally when my program comes up I make sure the other app is running.. and it would come up before you would click on something to try to call it.. but during the day.. maybe their app crashes.. so then right before I try to make a call to it I will check if its running.. so I want to run it up but kinda put a hold on my code while it waits..
so whats the best way to do this ? stop my code.. call a timer and when it see's its up call again ?? or can I put in some wait in the code then continue... just looking for the best method people have used..

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

Code is below. I am designing this code to transfer a file at a specified time. Right now, I have it sending me an email when it succeeds for test purposes. It will be only when the file copy fails later.
Here's my question: how can I get the program to wait until the file copy is complete to report success or failure? Right now I'm using exists to see if it works, but some other method of checking the file will be built in later. Eventually, this will be deployed to various locations for a bit of automated backup.

In my program, if something goes wrong an ErrorForm is supposed to show up and tell what was going wrong.
And if the error is a "fatal type", then I want the program just display the ErrorForm (which gives some information about the error), wait for a button press, and then close the program (terminate run).
In case of error, the form is displayed.. That's good.
But as the program is supposed to terminate after showing the error form, the error form disappears immediately after showing up (so it doesn't allow the user any time to read what's going wrong).
How can I make the program wait until a button press (on the error form) and then terminate?

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've made a gui for a cmd line program and I need to wait for the cmd line program to finish running before continuing.nd I have some code that starts the cmd line program and then calls a subroutine when it's finished running. But this method won't work since now I'm trying to run the cmd line program in a loop.Edit:Is there a way to just have the runtsmod subroutine (shown below) wait until the cmd line program is finished, instead of relying upon a subroutine starting when the cmd lineprogram finishes. This would simplify things greatly being able to call the sub tha starts the cmd line program and having it finish when the cmd line program is done.
Sub runtsmod()
'If the tsmod program exists in the directory the GUI is run from it is ran
Dim tsmod As String = Application.StartupPath & " smod_GUI.exe"

While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.
1:50:657: ============================= ENTER WebBrowser1_DocumentCompleted EVENT ========================================

I have an app that gets info from the internet into a label, the progam then decides which event will hapen depending on the info obtained, either load next form and continue or Application.Exit
My problem is that the speed that the info is returned from the net, varies and because the info is late sometimes the program exits when it should not.

In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.
The following is some example code.
Dim ChildForm as New frmTaskWindow With { .MDIParent = Me, .AddingNew = True }
ChildForm.Show
Me.Hide()
[Code].....
Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?

I've written a keydown event that needs to occur multiple times during the execution of a program, and it needs to play a sound each time. The first time the keydown event is triggered, the sound plays without a hitch. However, the second time (and all subsequent times) the keydown event is triggered, a system beep accompanies the sound. I'm using Studio Express '10 and I've already integrated e.SuppressKeyPress into my code:

I have some difficulties concerning threading [code]
Code:
1- Dim str As String
2- Dim x As New myClass
3- str = x.doSomething()
4- x.closeSomething()
I've included line numbers so I can just refer the lines by their numbers. My problem is, when the program executes, line 4 seems to be executed earlier than I want it to. It gets executed while ThreadX is still running in line 3. How can I force the program to wait until ThreadX has finished executing, before it executes line 4?

I am maintaining some VB.net code and I am more of a C# programmer. I have taken over maintaining several projects from people who have since left the project. The manager tells me that some of the VB.net programs are console applications. Yet in looking through the source code I am not able to distinguish wether the code is for a console application or for some other VB.net program like a VB.net windows application. Can someone tell me if there is a way to determine if a VB.net program is a console application.

i'm working on a project that simply changes the wallpaper periodically...it works fine...I created two seperate projects...1) a forms application 2) console application........The forms application gets the data and settings from the user....the console application reads the data and settings from text files created in the forms application and does the job of changing the wall paper...i've got mine set to change every minute...I realy want to get this finished, but am stumped by a few things....
1) how can i get my console application to run as a windows service..have tried the SC Create command..no good.
2)how can i get it so the console program runs as an icon on the system tray near the clock.
3)When i want to publish to create the setup.exe...should i somehow merge the two projects together or publish each one seperatly and use some sort of batch installer.

I have created an update program for my project, and I'm thinking what is better - to be GUI, or to be console app? Here's both pros and cons:
GUI: user-friendly,easy, but too much for so little program. It is unnecesseraly.
Console: Simple, but not user-friendly. And easy too!'s super easy!
