View 1 RepliesLaunch In Windows Safe Mode
May 3, 2012The problem is as follows: If Windows starts up in Safe Mode, no applications I make with VS 2010 will run. Even if I try to launch them, doubleclicking, running, almost everything I tried, the problem is that the application just doesn't show up. There is no window there, and I don't know (haven't checked) if a process related to the application is running.

Allowing Scalable Images In Restore Down Window Mode?
May 23, 2011I designed my program for my screen resolution (1680x1050) with all forms in maximized mode. I gave the program to a freind whose laptop has a lower screen resolution than mine. Now on a lot of the forms she cannot see some of the controls because of the lower screen resolution. I added the minimize, restore down and close buttons to the forms of my program but in the restore down mode the form does not scale down to show all the controls on the form. How can I incorporate scalabilty into the forms so that all the controls will be visible in the restore down mode.

Disabling Scroll With System.Console.Write?
Apr 11, 2009Is it possible to use Console.Write to place a single character at the very bottom right of a typical 80x25 console, without having the console scroll the row up? This is the code that I'm using...
Imports System
Console.SetCursorPosition(Console.WindowWidth-1, Console.WindowHeight-1)
Console.Write("x")
This is not working like I would like it to. Any suggestions or alternatives? I've tested that SetCursorPosition does use a 0,0 coordinate system, already. Using the WindowWidth-1/Height-1 should put me in the lower right corner of the screen... which it does, but then Console.Write is putting the "x" down and continuing on to the next line.

I don't just want to navigate to the same URL as in the original WebBrowser object, rather I want to repeat the HttpWebRequest.

View 3 RepliesVS 2008 List (Of T) Is Thread Safe?
Sep 5, 2009On the MSDN docs for the generic List(Of T) class, it says this:
Quote:
Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.but I'm trying to work out what exactly that means or why it matters. Does that mean that if I had this:
vb.net
Public Shared MyList As New List(Of MyClass)
then I could enumerate through that list from several threads at once without there being a problem? I thought you could read from any object from multiple threads without a problem anyway... I thought it was only if there were potentially other threads modifying that object at the same time that there were problems. Particularly with a collection like a List because you cant modify a list while another thread is enumerating the items in the list as you get an exception thrown stating that the collection has changed. I think basically what I am asking is if the MSDN doc said that a public shared list wasnt thread safe then what difference would it make?

View 2 RepliesVS 2008 - Safe Cancellation Of Unknown Threads
Jul 7, 2011I have got my multi threaded application running which is a Windows Service Project.
Basically when the service starts it starts a thread listening on a port for connections. The reason I started this on a new thread was so I could easily control it and not lock up that main worked thread.
Now on that thread when a client connects it dynamically assigns them another port number that is not currently in use and starts a new thread listening on that port and waits for the client to connect to do the actual data crunching.
So basically I have my main project thread, a Main listening thread then the possiblity of 0 to 100 more threads for each connected client.
Now this project should always be running but in the event it needs to be shut down (or server rebooted etc) I want to be able to shutdown the threads safely.
I can down my main listening thread safely but my trouble is all those other possible threads. What I would like is if the service is called to stop I want any of those other possible running threads which would have an active connection to the client to send a simple command like 'STOP' then close the connection gracefully (MyConnection.Close) and end itself.
The only solution I can think of which I don't really want to do is have a global varible (StopThreads as Boolean) and after each command in the thread check that boolean and if its set to true jump to some code to do what I want and end the thread but there must be an easier way? Or is this the best way?

VS 2008 Making A List Thread Safe?
Aug 26, 2009I am using WCF to make a chat application - I dont think the fact I'm using WCF is relevant for this particular question but just thought I would mention it in case there is something special about the way WCF does threading that I dont know about.So I have my WCF service that runs on a server and a WPF app that acts as the WCF client - each time a new client signs in or out it updates the server WCF service to let it know that it has changed status. The server then updates a list to either add or remove the user, so this list basically represents who is online at any one time. The list is declared in the core server class like so:
vb.net
Private Shared List(Of ChatUser)
So, I have a method in my server side that is called whenever a user needs to be added to this list and originally I thought I could have some issues because while the server might be looping through this list to find out who is online, another user might have signed out and the list would therefore be modified while the server was looping through it which would cause an exception. So I added the following to the start of the method that removes a user from the list:
vb.net
SyncLock New Object
and I havent had any problems... but I'm still not totally convinced that this will completely solve the issue. So would creating a Property give me a bit of extra safety? Assuming I always used the property to access the list in my code.
Like this:
vb.net
Private Shared Property CurrentClientList() As List(Of ChatUser)
Get
SyncLock New Object
[code].....
Also, am I actually using SyncLock correctly? I mean should I be referring to a shared object that all of the threads can access rather than just doing New Object each time or does it not make a difference?

View 1 RepliesVS 2008 - Log In With Email And Password And Make Keep Safe Items?
Jul 27, 2009i have created this programme which is basically a keep safe programme, well it's not created yet anyway.so far i have coded the the log in page, so the user can log in with their email and password.Once they do it comes to a screen asking if they want to visit their 'keep safe' items, or, asking if they want to deposit a file in their 'keep safe'.This is the programme belowThe Reason It say's JMEsseneger, is because i had other plans for the login until i came to face the fact, that im not quite fluant enough in this language to understand it all
1) As soon as they hit 'sign in' it creates a passworded.zip folder somewhere on their computer (using the same password they enterd to login and would only create the file if login is successful)2)The "Open SafeBox" obviously opens the file directory 3)the "Add To SafeBox" will allower the user to browes their computer for a file that they want to add into the "safebox" with a simple select and a click of an "add" button
