I am developing a vb.net desktop application that reads mails from the mailserver using pop and imap. The application is almost fnished .The problem is the some time when a command is send to retrieve a mail using GetMessage() functions the applications is going to a halt. So I tried to run the the code in debug mode and ran line by line.
What I noticed is in the while loop in GetMessage() function is
While Not tmpString.StartsWith(sPrefix)
tmpString = reader.ReadLine
msg = msg & tmpString & vbCrLf
End While
The reader reads line by line at certain point of time it got hangs. Some times it ill catch an exception and give an error. I am pasting the exception below:
"Received an unexpected EOF or 0 bytes from the transport stream".
But some times the applications will hang and go for a halt. This applications has to run 24/7. So if it hangs in the night or it will be problem. What I want is if the reader is not able to read from the stream after certain time period. The control has to be removed from the reader and the function has to return a message. I am new to this the network level applications and I am running shot of time.

Dim objTCP As New TcpClient

VS 2008 Network App - Send Message Or Network Package To Some Of The Clients In The Network
Aug 18, 2009Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

Custom GMail Vacation Auto-Responder (Using IMAP)
May 20, 2009I've always found deeper-knowledge articles elsewhere, but your community is the most co-operative and your forum article-editor is the best.I'm a Systems Engineer who works in an Anonymous Company. My indirect supervisor (my boss's boss) wanted to have a custom GMail Vacation Auto-Responder that would:Have a list of involved GMail accounts.2- Connect to GMail and identify unread messages.3- Auto-Reply to the senders of those unread messages with a custom auto-reply template.Well, this could have been done easily using the GMail Atom Feed url... but since the atom only provides access to the very latest 20 unread messages, it could not be used for that purpose.
So, I had only one of two choices, either use POP3 or IMAP. Of course, IMAP was the right candidate for many considerations, the most prudent of which is its resourceful command-set. I had to design the tool (a Windows Service in this case) with minimal data transfer/session time in mind, because Google becomes touchy when you over-use IMAP with its servers.I was new to the whole Socket/IMAP thing, so I had to get my feet wet. I designed the tool, planned it well, and thought the best work-flow would go like this: Well, my boss's boss had some comments - that he never really declared which makes them IMPLICIT :D :D :D - on the way the tool works, but he decided to spell the word only when I announced that my proto-type code is done. He is not supposed to be technically involved - I mean into code - although he really involves himself into bits and bytes, and he has not even seen the code, not to mention that he might not fully understand it, but yet somehow he declared that what I did was a waste of time.[code]

.net - Using A FileStream On A Network When The Network Drops?
Mar 26, 2012I am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).

View 7 RepliesNull Check Always Returns Null, If Removed Returns Object Reference Not Set To An Instance Of An Object
Jun 24, 2010I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu
If menuData.Children IsNot Nothing Then
menuData.Children.AddRange(GetChildren(menuData))
End If
Next
If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:
Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu
menuData.Children.AddRange(GetChildren(menuData))
Next
Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))

C# - Using SQL Server DB Over A Network?
Feb 16, 2012I want to use my SQL Server DB over a network. I have setup server client applications.The thing is for my current DB, I need to give it to server administrator who attaches the DB to SQLExpress instance and only then my network computers can access that.My question is, is there any way that my vb.net application could attach this DB through code at runtime, and DB gets all rights that are necessary to access it over the network?
I can attach DB using Create procedure but for this I need to know the sa password. Is there any way that I could achieve the same goal without sa passord and sa intervention?My only purpose is to enable my DB to be accessible over the network with all read /Write rights.
