VS 2008 Make TCPListener Wait For Full Command?
Aug 14, 2009
OK I am probably going to completely fail but I thought I would just try making an SMTP server (which came from another thread on here I was posting in earlier). At the moment I am just concentrating on RECEIVING emails via SMTP, I dont care about sending them yet.So the first thing I want to do is just make my server program be able to receive a simple HELO command from Telnet on port 25. Simple enough eh? Apparently not The problem I have is that my program starts reading the data as soon as 1 character is typed into telnet, rather than it waiting for the telnet user to press Enter before it starts to process the command. I've had a look around and looked at Athiest's examples but cant figure out how to make it wait. Here is what I have so far:
vb.net
Private Sub StartBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StartBtn.Click

When I use the Publish command in the Build menu pillar nothing happens expcept for a few seconds showing the wait cursor. This was working a week or two back but I have now installed sp1 for Visual Studio 2010 - is this a bug or is there some way. I can get this working again. I cannot access the project properties either, which is a known problem with SP1, so how to edit the project.vbproj file.

I have a background thread that sits waiting for new clients to connect to my TcpListener and when a new client connects it passes it off onto another worker thread and then loops straight back to waiting for another client. Like so:
[Code]...
Obviously I could just handle the exception and ignore it but I'm sure there must be a more proper way of doing it. One thing I am thinking of trying is using the BeginAcceptTcpClient and EndAcceptTcpClient methods but for one thing I'm not sure if that will actually help and for another thing the Begin and End versions of methods have always confused me in the past... I mean for a start how do you know when to call End?
I figured this must be a fairly common problem but searching the forum only turned up one result and it wasnt any use. I'll keep playing around and trawling google but just wondered if anyone had come across this before?

I am trying to learn how to use the tcplistener and tcpclient classes. While I am attempting to compare something that is sent from the client to the server it seems that it adds a bunch of spaces, the reason I know that is if I write to the console what was sent it adds a bunch of spaces at the end. Is there anyway to get rid of it and just get the original text. I tried trim() but that didn't seem to work but I could have been using it improperly.

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?

I have code that just runs and runs, and I'd like it to stop and take a rest. I want execution to wait for a mouse event and then continue. I can't just put the code to be executed after the event directly into the Click handler, because many different sections of code need to stop and wait for the event. I'd like the code to stop, wait for the Click event, then continue. I tried the test code below, but it pretty much hangs the program during the Do Until loop; I can't even press Button2. [Code]

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'm making a manually started screen-saver-esque program, and I need the "Black screen" form to be full screen, totally black and border-less.
I have so far managed to fix the last two criterea with changing the border style and form back color, but how do I make the form default full-screen?
The only settings I could find were things like "Manual" and "Center Parent". I'm probably just missing something obvious, but how do I make the form full-screen by default?
