I wonder how to make so if I press a button, then I want the mouse to move and click, but not before the progressbar is 100%. The progressbar is interconnected with a webbrowser.

I want the program to display the text "Waiting for connection..." while the program is actually waiting for a connection. However, when I run the program, the form doesn't even appear because the TCPListener is waiting. What can I do to have the program appear and show the text while it's waiting for a connection?
Imports System.Net.Sockets
Imports System.IO
Public Class frmMain

I keep trying different things I find on the net, but I can't get VB.net express to wait for exit. Hopefully someone can point me in the right direction here. Here is my code and all of this works but there is no way to tell when mugen stops.

I am a VB6 coder and I'm making the move to VB8 / VB.NET.I know how to wait in VB6, but my problem is that I don't know how to wait in VB8/VB.NET. I have a TextBox called textbox2 that contains the number of seconds I want to wait. I used to use wait 60 in VB6, but of course VB2008 is different.

I am practically a beginner at Visual Basic, and programming in general. I have created a simple falling bricks game in Visual Studio 2010. Every 100 milliseconds, it scrolls down bricks and if the player's position hits a brick, the player loses. I am having trouble with input.
I do not know how to make the computer accept left/right arrow keys as input, without having to wait for an input every 100 milliseconds. Here is the code:
Imports System.Threading
Module Module1
Dim RandomN As New Random

If I put "Input()" somewhere in the Animate sub, the program will invariably go wrong. How can I make it work?

I am trying to make a marquee progress bar run while my long function is running. When the function is done running, I want the progress bar to disappear.
[code]...
If I don't do t.Join(), the progress bar disappears right away and then the thread runs. If I do Join(), the progress bar doesn't appear until the message box pops up after the thread is done!How would I get the effect of the progress bar running while the thread is running and then stopping when it's done?

I am writing an application to perform an automated task on a website. I am trying to write a script that logs into the website, then loads a certain page. I have to execute a javascript function after filling in the username and password on the login, but the WebBrowser object doesn't wait and does not log in. As a result, it loads the next page while not logged in. How can I wait until the application logs in before loading the next page? I tired using
Code:
Do While WebBrowser1.ReadyState < 4
Application.DoEvents()

I have a problem with an App I am writing that lists information about various media on your computer and lets you launch it right from the app. My problem is, when launching an intensive process, like a game for instance, it is desirable to shut down the app to not hog precious resources. Here is the code i have so far...
[Code]...
This code works fine, but for one small detail. The app exits before the desired process starts, thus cancelling out the process all together. My question is, how do I get the app to wait for the process to start before exiting?

What is the proper way to call up a form and wait until it receives a replay before moving onto the next code step? [Code] Now lf is the login form that waits for the users password and then, depending on if its correct or not when they hit OK it should send back a true or false (isLogedIn). Currently i do not know how to have the code wait until it receives something from the login form before moving onto the next code.
If i use my old code here:
Do Until isLogedIn = True
isLogedIn = isLogedIn
intX = intX + 1
Loop
It never ends if the user puts in a false login password so it just keeps waiting.

I am trying to use a separate thread to handle specific events in VB.Net. The idea being that I do not want the main application to be held up if a particular event handler takes awhile to finish. How do I get my main thread loop to suspend the thread while allowing it to handle events when they occur?When I create a Windows Forms application, there is a UI thread that handles the UI events. I do not imagine that this thread is continuously polling some variable to see if someone has pressed a button. I imagine the thread is suspended until the OS tells it there is something to do. I was trying to figure out how to ensure that my event handlers were not being executed by the UI thread. From what I have read, I can do this by raising the events from a different thread. But what does that thread do while it is waiting for other events, just exit?
I wanted to know how to create a thread that works like the UI thread, only it processes the events I want it to process. I am not sure how events work in .Net. I understand that event handlers are run on the thread that raises the event. I believe that .Net allocates threads from some thread pool to process events such as timer events. I am not clear on how it works, though, and what those threads are doing when they are not handling events.

I have a basic question about timers, that I can't answer myself. It's annoying me. My code is made to visit a website every X seconds. There are two problems.
I Set the interval for 30 sec and the first visit should be right now, not after 30 seconds.
After that, wait 30 sec and navigate to another one (in a listbox). The problem is that the Timer is not waiting that time after the first visit.[code...]

Recently in a couple of my current projects I have found that I have the need to 'schedule' events in my applications. For example, I would like something to happen in my program at 11 PM every day (and no I dont want to use Windows Scheduled Tasks) but I cant think of a good way to do this... The only method I can think of is to just have my app check every minute to see if the current system time is 11 PM but obviously that is pretty rubbish. I considered using Windows WorkFlow but that seems very overkill just to do this one thing...
Oh and if it makes any difference, I would like the user to be able to modify these times that certain events occur.

i'm trying to make the program wait while the webbrowser document frame loads. I'm using the code below, but all that happens is the page load pauses while the do loop happens (which obviously will be neverending as the search function searches for a line of html particularly present in the page i'm waiting for the webbrowser to load).

I have a vb program accessing a table in an sql server database. I would like the vb program to wait if it attempts to update a row which is locked in the table. The default behaviour of the recordset seems to be fail immediately with a timeout if the record it wants to update is locked.
The sql server is set to a default lock_timeout of -1 (infinite I believe). Is there a way to have an ADODB recordset wait on a lock (say for 60 seconds) and then fail if it still can't update the record.

I have a strange issue when binding a combobox in a WPF window.I am loading a List object, to populate the combobox, through it's .ItemsSource, on Window Load, however, it does not populate.At least, not until the arrow is clicked on. Once the arrow is clicked on, the window freezes up, and after a minute or so, the 4000+ records are displayed in it.Now, the list gets loaded, however, when I click on the combobox it takes awhile for it to render, so how can I show a waitcursor while it is rendering the list?Here's the Xaml for it:
<ComboBox Grid.Column="1"
HorizontalAlignment="Stretch" Margin="3" Name="tUser" VerticalAlignment="Stretch"
DisplayMemberPath="UsersName" SelectedValuePath="UserID" SelectedValue="0"/>
And the code-behind is:
Private Sub CreateTask_Loaded(sender As Object, e As System.Windows.RoutedEventArgs) Handles Me.Loaded
Using New WaitCursor
_LA.Show()
Me.tOrder.ItemsSource = GetOrderList()
