Im using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...

And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.

View 3 RepliesI'm writing a VB.NET WEB application and I'm fairly new at it. What I want to do is open Excel workbooks on the client workstation so the user can "Save As" or print or basically do whatever they want with it past that point. I've done this in a windows application using System.Diagnostics but all the information I've read so far doesn't seem to work. I can open .txt and .xls files using this approach:[code]but it opens in the browser, which is not what I want. Do I need to mix Javascript with the HTML and the VB code?
View 2 RepliesI'm building application that will heavily use database (about 25k query's in few hours) , what is the best way to go:
A) use datareader and open new connection to the database on every client query.
B) load all the needed tables into dataset once the program loaded and use that dataset for the query's?
this is probably easier than I think it is.I would like a client-to-client messenging system without using Winsock if possible. At the moment an IP based connection system would be okay.
View 8 RepliesI'm using a "wsHttpBinding" with a reliable session. I'd like to keep the client-server connection endless open. Therefore I need to set the ReceiveTimeout to "infinite". Has the "ReceiveTimeout" an other purpose (e.g. client crash detection; detecting a hanging request; etc) or can I set it to "infinite" without problems?
View 1 Replieshow to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
View 9 RepliesWe are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

i have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can
vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.
[code]....
i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??
I want to place 24 check boxes on a form. I want to enable drag and drop for each and place the code to handle the drop on a customized check box, then create each check box from the custom check box.

View 2 RepliesAt the top of my form, I have a status strip with the common "Window" dropdown that is seem in many commerical and Windows Applications. What I am attempting to do is the same that can be done in VB2010 itself. In Visual Basic, clicking the Window Dropdown allows you to choose which window is active. My whole point on this is that they are using a customized Image.Here is an image example from a program called Paint.NETIn the area of the dropdown, you can clearly see that the "Checked" images are customized. For example, Tools is showing the hammer with the glass button frame over it.What I want to know is how would I achieve this customized image set? I already know I would need at least 2 images, one for checked, one for unchecked.

One class in the library revolves around the cart header. This class is consumed by a web project.

Suppose I have a Microsoft Expression Blend. Is it possible to create a custom control (such as a button) in MSE Blend and then import it to visual basic 2010?For example, I want to create a custom shape button (different from what is available in the toolbox in VB2010) (like for example a pen-shaped button) in MSE Blend. Can I import it to VB2010 to be used with Windows Forms Projects? If yes, how?
View 1 RepliesI'm attempting to create a customized dictionary object, because I want to add some code to the Add routine, and I can't just inherit because Add is not overridable.
So I'm creating a class that implements IDictionary. Already I am confused, because Dictionary implements a lot of interfaces, listed below:
Implements IDictionary(Of TKey, TValue), ICollection(Of KeyValuePair(Of TKey, TValue)), _
IEnumerable(Of KeyValuePair(Of TKey, TValue)), IDictionary, ICollection, _
IEnumerable, ISerializable, IDeserializationCallback
But IDictionary inherits ICollection and IEnumerable, so why implement all three (and don't they have overlapping methods)?
#2, when I implement IDictionary, the code fills in two Add methods (one for the ICollection add of a keyvaluepair, one for the Idictionary method). Apparently both these add methods are required for Idictionary, yet a regular dictionary (which implements IDictionary) only has one Add method that I can see. I actually would like to have only one Add method if possible. Why am I being asked to make two (and that's before all the other interfaces have been added)?

View 1 RepliesI have created a customized list (by implementing IList) where I added a few special methods. Sometimes (but not always), I only want to expose this list as read-only. To do this for normal lists, I use the Collections.ObjectModel.ReadOnlyCollection wrapper, which works fine typically. But it seems by passing my customized list through this wrapper, my added methods are no longer visible, which defeats the whole purpose of having this customized list object in the first place. How can I create a read-only version of a customized list?
View 2 RepliesI have created a customized control in which i have used some different property names. For eg. if the actual property name in the base class is "Text", i have used the name "CtlText" by internally implementing the "text" property with some additional checks. Now i want the user to use only "CtlText" property during coding. Currently the user is able to see 2 property with same functionalities.
Is there anyway i can surpress the using of a property during runtime?In design time we can hide it using the "Browsable" attribute, but i need to hide the same during runtime also.
