VS 2008 Firewall Blocking Emails
Jun 11, 2010Me and my friend both wrote an app to send emails, same code. When I run my app, I can let it send an email. When I run my friends app, the firewall blocks the outgoing emails. Is there any way to let the emails send from my friends app, by changing code or so? I don't want to add it to the whitelist of the firewall.

Check If Port Is Blocked By Windows Firewall?
Aug 15, 2011How do i check if specific port is blocked by Windows firewall , both in incoming and outgoing connections.
I've seen code samples such as this one:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim host As String = "localhost"
Dim port As Integer = 6900

But how can i know if the exception is thrown specifically because of firewall blocking, and not because of other socket errors?
Use Windows Firewall To Control Security Board In .Net?
Jun 12, 2011I am trying to control the security board using the Windows Firewall which connects to my server that was made in VB.Net. My only problem is when I open the Windows Firewall my server crashes. It also displays this error: "Error, win%fir%90y4e does not support this server. upgrade you version of Winsock.". So I upgraded myself to the latest Winsock that there is out there. After doing so I try again and my server still crashes, but this time with a different error. The error this time was the following: "Error, no client is available for win%fir%90y4e. try again later.". What do I do?

.net - Expose WCF Service Cannot Retrieve Object Through Windows Firewall?
May 13, 2011I built a WCF service that exposes itself for a web application, it accepts an object and prints the data on the clients machine. Works fine on my development machine, and the service is up and running on any machine i install it on. I can enter ip address in clients machine web browser and see it is running. Problem is when i send the object to the clients machine it returns an error, that sounds like it could be because of the clients windows firewall. Where would i start at to deal with this problem ?There was no endpoint listening at http://192.168.1.168:2202/PrintLabel that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

View 1 RepliesCompany Firewall With System.Windows.Forms.WebBrowser
Nov 22, 2010VB2005. In my application I am required to go to a website, collect info, and then display both the webpage and the info collected. For this I am using the System.Windows.Forms.WebBrowser component and have it working faily well. The only thing now is that in order to get to external websites the company requires us to login to the firewall proxy server. For example when I visit [URL] a login box pops-up for our firewall server [URL] and I sign in with ID 9999 and password "pass". I am trying to programatically do this with the WebBrowser by using the credentails but have not found any relevant examples. Is this possible with the System.Windows.Forms.WebBrowser component?

Blocking In A Service?
May 25, 2012The subject sucks, but the problem is straightforward. I have an existing WCF service. There are a small series of functions, currently. One or two of the functions will need to be performed with a bit of security, for which I need a username and password. The username and password will be checked on the server side against a webservice running on localhost. One alternative is to not use the localhost webservice for the validation, but then I wouldn't have a question, so ignore that.
The way the webservice will work, I was thinking that I would use an invisible web browser, navigate to the REST-style URL, and wait for the response. It's the bit about waiting for the response that is causing me trouble. Normally, I'd wait for the document comleted event raised by the browser control, but since this is initiated by the call of a WCF service function, that won't really work. The WCF function call can't 'wait' for anything, nor will it receive the event. Once the WCF function reaches the End Function statement, it is over and done with, and returns. The response from the webservice won't have arrived by then, so that won't work. There are two typical solutions to this, one of which is horrible to the point of being unworkable.
1) A busy wait, or spin wait, where the WCF function goes into a tight loop waiting for the browser event to be raised. This is never a good idea, and is particularly terrible in this case, because the WCF service is running on a web server, so the negative impacts of a busy wait are FAR worse than normal.
2) Use something like a Mutex in the WCF function such that the function launches a thread, the thread immediately grabs the Mutex, then begins the navigation. The WCF function waits on the Mutex, which would mean blocking without spinning, and the document completed event pulses the Mutex to release the WCF function so that it can return the proper response. This seems technically improbable, as it stands.
The problem is only a slight variation on a very typical problem, yet it presents some interesting problems. Windows is event driven, but a WCF service function is not. A callback across a WCF (at least across this one), isn't an option, events aren't an option, so it all comes down to the function starting a process, then blocking without spinning, until the process comes up with an answer.
C# - Blocking A Thread In .Net?
Aug 13, 2010I have a class that has purely static Methods and properties. I am calling an async method on the class "Load" that asks a web service for a chunk of data, which then fires an event that executes the return method, "LoadCompleted". I have no idea how long the call is going to take (the difference between calling the "Load" method, then the "LoadCompleted" getting called).
I would like to block the application from proceeding any further until the callback method has been raised (as the app will try and get stuff from this class, which isn't populated until the "LoadComplete" method sets the data).

View 15 RepliesNon-blocking Task.wait In .NET 4?
Apr 30, 2012I'm trying to wait for a Task result in .NET 4, much like you can by using the await keyword in .NET 4.5. I just can't figure out how to do it though...My code (to prove that I'm atleast trying):
Private Function GetXDocumentFromWebLocationAsync(ByVal request As WebRequest) As XDocument
Dim queryTask As Task(Of WebResponse)
queryTask = task(Of WebResponse).Factory.FromAsync(AddressOf request.BeginGetResponse, AddressOf request.EndGetResponse, Nothing, Nothing)
[code]....
As you would expect, the GetResponse calls are executed on a different thread, but the function has to wait for the result before it can return. Unfortunately this blocks my main thread until the task has completed and I don't have the slightest clue on how to make it wait without blocking. I don't want to use the Async CTP either because that's just running away from the problem.
