Step Through App, Stop, Restart, Now Get "Only One Useage Of Socket Permitted"?
May 25, 2010
So I'm opening a TCPListener on socket 8000. Debugging code, finding bugs, stopping the app and debugging again. Somehow I'm causing a problem such that it's not closing the TCP port, and it's causing a major problem such that even after I stop my program and restart it the code to open the TCP port the app is still throwing an exception, and it keeps happening until I reboot.It's going to be real hard to find the bug when I have to reboot each time to debug the app

I have 1 process that acts as a server (TcpListener) and one or more processes that act as clients (TcpClient). The clients are sending Tcp requests to the server every 1-2 seconds to which the server responds with a result message.
In normal conditions the server will use TcpListener.Stop when it closes, but sometimes the server will crash (for whatever reason) and then this is not done. If I then try to restart then I get the following error:
"Only one usage of each socket address (protocol/network address/port) is normally permitted"
I only get this error when there are clients running who keep trying to connect despite the TcpListener is not there anymore (crashed).I don't get this error when I first manually close/kill all clients before restarting the server/TcpListener.I'm looking for an automatic recovery procedure that deals with this error/problem. How can this be done?Below you'll find code examples of the server and the client.BTW: Although the codes examples are in VB.NET, I can also handle C# code. That's why I tagged this question with both VB and C#.Code example for server/TcpListener:
Public Shared Sub Thread_TcpListener_GUI()
While True
Dim tcpClient As TcpClient = Nothing
Dim tcpListener As TcpListener = Nothing

I have a start and stop button on a form and would like a pause and restart button aswell.
I can start my audio file (WAV file in the C-Drive) fine with;
My.Computer.Audio.Play("C:Bleep_TestBleep_Test.wav", AudioPlayMode.Background)
Thus allowing other functions to be carried out.I can stop my audio with;
My.Computer.Audio.Stop()
But i would like to be able to pause and restart the audio?There are timers and getkeystates envolved with this form. The timers I can pause and restart, the getkeystates are a function called in conjunction with the timers as a case statement, (all this is working).how to pause and restart the audio, bearing in mind the loaction and the other features of the form? (I only wish i was a clever as you guys/girls out there to return the help rather than leaching your knowledge continously)

I am using the following code to create an array consisting of double values specified by start stop and step. The problem with that is that for some weird reason there is a calculation error that seems to originate from the for statement causing the values to drift after the 11th to 12th digit after the comma which is quite irritating for the purpose i am using it.

I am running Microsoft Visual Studio 2008 Professional on a Windows 7 system. While working on the visual basic exercise in chapter 4 of the Microsoft Visual Basic 2008 Step by Step book on the MyMenu program I added a Toolstrip to my form and then I was trying to perform the add OpenFileDialog and ColorDialog controls to the component tray as described at the bottom of page 111 under Using Dialog Box Controls. I could never get the controls to appear in the component tray as instructed in the book.

I have a program that plays a video and uses the step function to move frame by frame backwards and forwards through the video. The forward frame works just fine:
AxWindowsMediaPlayer1.Ctlcontrols.step(1)
However, the backwards step (below) jumps a full second backwards while the forwards step only steps .033 seconds forward (presumably a single frame).
AxWindowsMediaPlayer1.Ctlcontrols.step(-1)
I can't find any documentation about this problem online and in fact I can't find much mention of this function.the documentation does say the -1 command should step back one frame. IWMPControls2::step method Is this a known bug or is there an updated function I should be using?

My need is to work with what I have (2005 studio), what I know (Visual Basic) but need a primer. I am a visual learner (so I need to see [1] how the form is created, named and set up). From there I need to see [2] how he code works so that I can implement from there.

I have a wizard where users need to fill out data. You cannot navigate to the second step until first step is completed.
I enforced this behavior by disabling/enabling "Next" button, but I really do not like this solution, since it seems not really elegant or safe here. What is the good approach on building step-by-step processes with enforcing step completion.

I seem to lost the practice files disk for this book, and I am trying to 're-learn' this book. I am unable to do the lessons without the practice files. If you have the disk and could maybe zip them up and email them to me? I have the other disks still, and am using the Visual Studio Express to do this.

When I started to work on this new project in vb.net 2010, I put many breakpoints to try to understand the execution order of the project, only to find it in vain. Step into command F11 should work correctly according to Visual Studio 2010: Step Into Property/Function(F11) doesn't work as expected. But I when I pressed F11, I found the code is jumping from one place to another based on breakpoints, not line by line or step by step.To give an example, please see the code below
Me.tcData.Alignment = TabStrip.TabControl.TabAlignment.Bottom 'line 1-breakpoint
Me.tcData.Dock = System.Windows.Forms.DockStyle.Fill 'line 2
...
Me.tcData.TabsDirection = TabStrip.TabControl.FlowDirection.LeftToRight 'line 3
[code]....
When I press F11 at line 1, it goes to the property 1. After it returns, when I press F11,it goes to property 3 directly, without accessing the code in line 2 and line 3.I do not understand why the code is NOT executed step by step by using F11. If I put breakpoingts in line 2, then line 2 is executed.So it seems to me that the showed execution order is based on breakpoints! So if I put breakpoints at different places, the showed execution order would be different! Thus, it is impossible for me to really understand the execution order.

I wrote a Socket Client which will send the Socket Server some data and get some response from Server. This process will be running once in every 2 seconds.
Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.

Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

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.
