VS 2010 WebControl.dispose Does Not Stop Iexplore Process?
Oct 13, 2011
I call the method GetUrl below provided in a form-based assembly from a console application to get the content of an HTML page. This works fine so far with one exception. The code starts an iexplore-process in the background and this process remains active even after fnishing my program. The only way I found to get rid of this process was to kill the process, but this seems not be be a very nice and mature solution. I already read that the NET webbrowser control in only a wrapper for an activeX COM control of IE.
Question: How can I close the newly created iexploe-process in a clean way using the webrowser object?

My app starts an On-Screen Keyboard process like this:
Dim PID as System.Diagnostics.Process
:
PID = Process.Start("C:WindowsSystem32osk.exe")
:
[CODE]...
It seems to work 90% of the time. However, sometimes the PID.Kill() fails because it says the process already exited. At this point the OSK is always still there on screen. Yes, I know my code should be testing to see if the process is still running before trying to kill it, but given that the OSK is still on screen..

I'm not asking how to exit the program( dispose() ) instead I have a program that checks if a certain process is running and if so it displays a message box, stops the process and (Should) exit the program. If the process is not detected then the program loads normally and opens an external program. My problem is that it stops the process and still runs the program. How can I fully stop the code and exit my program?

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

I would like to be able to stop a loop while executing using the ESC key.I've found a lot about using the above key from within a Form (for example, to unload it), but very little for the use of the key within a Procedure (Sub, Function) and particularly with respect of preventing a loop from carrying on execution.

what is the method to tell when a user starts or stops a process? My company makes a software package that allows a tie in from vb. I want to make a package to allow me to start and stop the software remotely and to monitor when the software is running or not.Ideally there would be some sort of event in windows when the user starts or stops the software. I imagine there is some sort of way to do this with a timer, but I am sure that windows will have some sort of event process when the program starts. I have googled this and looked through the xtremevbtalk forums for this but I am not quite sure as to what keywords to use.

I develop an appliaction which is running a process in the background. This process is "forked" from the application (I'm not using threads). The process may take a few minutes while the 'father' application is waiting to the process output, so I'd like to enhance the application with the following:
a) a "Stop" button (like in IE, FireFox) to stop the process in background
b) A status bar that displays what's going on while the process is running in BG.
how to draw a button or status bar of course... I mean how VB.NET handle with stopping or displaying while something else is running in background and how to do it.

When I go to Debug my program (F5), the program will load, until I click on the form with the main part of code in it, and then the program freezes, although it doesn't lock up because as soon as I press stop debugging/ task manager end process, it closes fine.
I will attach the zip of the program here. The form that it freezes on is "Black Ops". Edit Due to the forum not accepting my .Zip file (Invalid file type), I will upload it to MediaFire. Download link (445kb): Click Here

I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

I'm playing an audio file like so:
VB.NET Dim audio As New Audio(Application.StartupPath & "est.wav", True) audio.Balance = 10000 audio.Play()
Which works great. But if I need to change that file, I get an UnauthorizedException because the I haven't disposed of it. But, if I add a dispose after .Play, it won't play.

I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")
[Code]......

An application that has 3 Webbrowsers instantiated at design time navigates to webbrowser2 15 times every minute with a different webpage. Webbrowser2 is disposed of after each web page is received and processed. The size of the private application memory continues to grow as when the disposal was not instigated. The application memory grows to 1GB and then the program stops responding. Any suggestions? [Code]
