Yes. It's not the language or the .NET Framework that will be limiting you. It will be the server software licensing (Windows Server that is...) and the design of your chat server.

You COULD use VB6 but I wouldn't recommend it since it's essentially deprecated. Writing the clinet in VB.NET will give you the most flexibility.

I'm creating a few programs for chat/email purposes. The idea was for there to be no central application and each program connect to the others kinda like in a p2p network (i think). I've not really got any idea how they are going to know what ip to connect to if each time the user connects to the net they get a new ip. I'm using networkstream and tcplistener/client because thats all I know how to use. Any ideas or even pointers towards classes better suited to this would be great.
Thanks

That's the whole problem of any P2P network: finding peers. There's not a single solution and not a perfect solution. You can try connecting the last peers seen, have a central server for locating peers, or some always-on, highly-reliable peers.
Yes, even I am blogging now!

I am wanting to create some small apps for Pocket PC. I have VB .NET 2003 Standard. I have installed eMbedded C++, eMbedded C++ SP4, and the CF 1.1 SDK. I still see no option under new project to create a VB porject for Pocket PC 2003. I DO NOT want to do a C++, J++, or ASP project but VB .NET CF app. Can anyone help me? What have I not instaled/configured? Does this only work with the PRO version of VB? I have searched and searched but the hits are overwhelming and generally unrelated to setting up to create apps in VB for Pocket PC.
Thanks for any help,
Glisson

Not sure about that.

It's NOT supported on the Standard or Academic Editions. You must have the Professional Edition or better.

Thanks for clearing that up. Even thought it's not the awnser I was looking for! Man that is a bummer! Looks like I need to start watching E-Bay. I can't justify paying retail for no more then I have planned or am likely to accomplish. LOL
*EDIT* I forgot about the Acedemic versions. I started digging up some more info and according to this site msdn feature comparison, it IS supported by the Acedemic version. Guess it's back to school for me. LOL

Hi,
I am building a simple windows form which mimics the windows media player.
It user the wmplayer control, and has as transparencykey white.
For some reason the player does not play the video files correctly. I hear
the audio part but the video part is not displayed, except some flickering
iat the start. If i dont have any colors as transparencykey it works fine.
How do I fix this issue?
thanks

are you using a bitmap or picture loaded as a resource?
If you are then load it as a file instead I have seen this be an issue before.
|
|
|
|
|
I just specified the a png file as the background image of the form. How would I load it as a file?
thanks

|
|

Me.BackgroundImage.FromFile("c:\windows\clouds.png") ' whatever your path and file is.

The problem exists even if I dont specify a background image.

I am writing a distributed transaction code. My current scenario include a client database(Suppose client- having 4 main database) which can be installed anywhere which would connect to a public database placed at ISP datacentre(Suppose Server- having 2 database[host,transmissionqueue]). this server database is added to client as linked server through vb.net interface. i have a transmission routine which transmitts the data from the client to Server and update client transmit field. If i implement the distributed transaction in this scenrio is there any alternate to MTS . I m using the distributed transaction through vb.net interface using transaction object and setting 'begin distributed transaction' and 'set xact_abort on' and 'SET NOCOUNT ON' and 'SET REMOTE_PROC_TRANSACTIONS ON' options.
Sample code
''Start (Coding in VB.NET/ SQL Server 2000 backend on windows XP)
Public Function TransmitFiles(ByVal filepath As String, ByVal oDtTransmit As DataTable, ByVal iStation As Int16, ByRef TransmitErrorDetails As String) As Int32
Dim myConnection As SqlConnection = New SqlConnection("Data Source=shabbir;Database=AGS_LOGISTICS;UID=sa;pwd=SA;")
myConnection.Open()
Dim myTrans As SqlTransaction = myConnection.BeginTransaction()
Dim myCommand As SqlCommand = myConnection.CreateCommand()
myCommand.Transaction = myTrans
set_OPtions_on_database(myConnection, myTrans)
myCommand.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')"
myCommand.ExecuteNonQuery()
myCommand.CommandText = "INSERT INTO [192.168.1.181].AGS_TRANSMISSIONQUEUE.DBO.MANIFEST SELECT * FROM MANIFEST WHERE ORIGINSTATIONID=9007 AND TRANSMITTED=1"
myCommand.ExecuteNonQuery()
myTrans.Commit()
myTrans.Dispose()
Console.WriteLine("Both records are written to database.")
Catch e As Exception
myTrans.Rollback()
end try
end sub
''End
Different problems are coming at different time
1- The problem is that transaction object is running fine but its not inserting anything in the database.
2- the executenonquery is returning -1 even where it is returning the correct record affected count without the transaction object for this command.
3-sometimes giving SQL server not found or Access Denied from the front end.
4- Some times SQL log is showing
2004-08-14 07:55:35.46 server Attempting to initialize Distributed Transaction Coordinator.
2004-08-14 07:55:35.53 server Failed to obtain TransactionDispenserInterface: Result

?????Can some body explain what is wrong with my coding or wht setting to made in the system?
* I m using window XP professional and .NEt studio 2003 and MSSQL 8.0
one of my testing server is also the same confing and other testing server is windows2000 server.
Important : will i have to install MTS on each client or server only if i went for Distributed transactions through DCOM and MTS?
Will i face any difficulties regarding the com registration?
Can some body provide some short sample project?
or Can some body provide some Code sample for the transaction class and how to configure in the MTS?
Can some body provide Some helpfull links to clear my concepts and helpfull in implementation and code?
All your help would be highly appreciated.
Regards,

Is your server's IP address changing...
It looks to me like you have a network router/hub, Firewall or Unconfigured Qos service, problem.
Failed to obtain TransactionDispenserInterface: Result Code = 0x8004d01b
0x8004d01b "The transaction manager is unavailable" .
It is possible that DTC is shutting down unexpectedly.
SuperSocket Info: Bind failed on TCP port 1433.
(would not bind if DTC is in a shutDown State)
http://support.microsoft.com/default.aspx?scid=kb;en-us;319578&sd=tech
"Important : will i have to install MTS on each client"
You can use the MTS Explorer to distribute components to a client machine whether or not that client is running MTS. If the client is not running MTS, MTS can generate an executable that will automatically install and configure clients to access remote MTS server applications. The client must support DCOM for this procedure to work.

If your using Vb 6 take a look here.

Thank you, but I have a problem while I have a small project in vb6. I used to develop vb6 as interface and access as database. I used DAO as database engine to connect between database and its interface. The problem when I faced is package (create setup file) with package and deployment wizard. Whether I take a loot at MSDN at microsoft I still have a problem. Some screen of its wizard made me confuse and don't understand (I just guess and pass through it). It made me very difficult when I deploy my application to the other computer. Can any one give me a step by step guide?
