View 2 RepliesIn my scenario, users are able to upload zip files to a.[url]....I would love to create a "daemon" which in specified time intervals will move-transfer any zip files uploaded by the users from a[url].....From the info i gathered so far,
The daemon will be an .ashx generic handler.
The daemon will be triggered at the specified time intervals via a plesk cron job
The daemon (thanks to SLaks) will consist of two FtpWebRequest's (One for reading and one for writing).
how could i implement step 3?
Do i have to read into to a memory() array the whole file and try to write that in b.example.com ?
How could i write the info i read to b[url].....?
Could i perform reading and writing of the file at the same time? No i am not asking for the full code, i just can figure out, how could i perform reading and writing on the fly, without user interaction.I mean i could download the file locally from a.example.com and upload it at b.example.com but that is not the point.
I will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.
View 2 RepliesI really need to know if its possible because I'm making a messaging client since me and my friend find believe MSN is getting buggier. I've looked on how to do it but none of them worked for me, or were server to client. I want to make it client to server to clients but I don't know how! I know I shouldn't tell you to give me code but maybe give me a few tips on this. Me and my friend share files nearly everyday.
View 11 RepliesI'm using server.transfer to transfer execution of a URL to a dummy page which fetches information from the database. The trouble is that the master page interacts with the session.
global.asax:
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
' Fires at the beginning of each request
If Not (System.IO.File.Exists(Server.MapPath(Request.Url.LocalPath))) And Request.Url.LocalPath.ToLower
[CODE]...
Master page:
If String.IsNullOrEmpty(CStr(Session("SessionId"))) Then
Session.Add("SessionId", Guid.NewGuid().ToString)
End If
Page declaration: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="utilityCMS.aspx.vb" Inherits="utilityCMS" MasterPageFile="~/MasterPages/main.master" EnableSessionState="True" %>

<add name="HttpModuleAggregator" type="XPIdea.Web.HttpModuleAggregator,xpidea.web.common" />
</httpModules>
I'm getting an error :
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I should also mention that this same master page works elsewhere in the site. Session is used throughout the site as well (not just in the master page).
I have herd that a new type (or old type) of connection when the server connects to the client. Is it really possible to do such a thing with mulit-Servers trying to connect to one client.How would I make one like that O.o.
View 5 RepliesWhat are the basics to creating a tcpclient / server?
View 3 RepliesI have a simple tcpclient/server messenger running. Everything works great, except for when a client exits the software. When someone exits, is crashes the server with various exceptions and the server has to be restarted, as well as the clients. What I am looking for is a way to properly "log out" a client BUT leave any other connected client on so that is no break in the chat. Then the person that logged out or a new person can join back in whenever they choose.
CLIENT
''CHAT SERVICE
Dim clientSocket As New System.Net.Sockets.TcpClient()
Dim serverStream As NetworkStream
Dim readData As String
Dim infiniteCounter As Integer

I have a .Net program that has to run on a cluster of server 2008. To find out the right IP I resolve the dns by GetHostEntry(VarDefinedInfConfig).AddressList(0)
but when I am converting my old code (this code picks the wrong IP) dns.GetHostName().AddressList(0) => this returns a virtual IP and not the right one.So I changed my TcpListener to (dns is parameter from config)Dim listener As TcpListener = New TcpListener(New IPEndPoint(Net.Dns.GetHostEntry(dns).AddressList(0), 8001))
listener.Start()

Am using this code to connect to an SMS server to send sms to mobile phones but am getting stucked at the the bold like below:
[CODE]:.....................
However I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).

I want to know how you can export data from a disconnected database that could be access or ms sql to an sql server database.
Here is the scenario:
I have several software in a remote sites on either sql or ms access databases as back-ends...and I have another sql server database that i want to consolidate data from the remote sites.
One solution I have been thinking about is to use email to send incremental backups of the databases to the main database using a separate piece of software and have another one on the main server to pull that data into the database.
Basically am looking at setting up the remote databases as linked servers at the main database and then having incremental backups sent by email to the main database.
I have thought of replication but the internet link at the sites is terrible.
Is that a good implementation? If yes
How do i get to send the incremental backups and get them imported?(the code)
Tools:
Visual basic 2008 standard edition..Net 3.5
SQL Server 2005.
32 bit architecture.
I found similar forum thread [URL], but he don't have answers. How I can conncect | send | recive data using tcp connection with specific internet service (not web).

I created two forms in asp.net, there are test1.aspx and test2.aspx. The test1 page contains one submit button. If the user clicks this, I do transfer to the test2 page by using server.transfer method. In this situation, the browser will show the test2 page content but the address bar of the browser will show the test1 page location. When the user clicks the refresh button of the browser or F5, the test1 page is worked and the submit button is worked. I don't want to work this. I want to refresh the test2 page. How could I do that? I don't want to use response.redirect.

View 9 RepliesI have a host page with multiple user controls in it. Some of these controls have a user created property named Enabled, and is boolean.In some controls the default value for Enabled is set to False. In the host page, I am able to access the property and set it to True. The control does what it is supposed to.On this host page there is a "Run Report" button which executes a Server.Transfer to a "Results" page.In the codebehind of the results page, control values from the PreviousPage are checked via other user created Properties for the controls and added to a ParamterList.
I am attempting to check the Enabled property of the controls on the PreviousPage, however when this is done, it appears that the Enabled property is set to that of the default (in this case False), and not what I had set it to on the page when it loaded.Does the value of this property need to be put into a hidden text box or something so its value is available after the ServerTransfer? It seems like any control which contains a value is retrievable via the PreviousPage and its user created property, but any variable set inside of the control is reset back to its default value.
For my application, I have a page that redirects to another page (within the same application) via Server.Transfer. I need to do this because the original page has an object that I need to access by using the Page.PreviousPage property.
Once my "destination" page has been fully loaded, a local deep clone that I made of the source page's object is suddenly released from memory once I perform a postback? Is this by design--something to do with the Server.Transfer?
Page1.aspx:
Public Structure myCustomObject
Implements ICloneable
Dim someField as String = "default value" ' Default value
[code]....
At this point, EVERYTHING works as it should. Stuff got cloned over correctly and all is well.(Let's say this is on a button click event) Debug.Write(newObj.someField) ' Output: "default value"<- This is NOT "changed value from source page" for some reason when it was working literally a few lines ago! My guess is that the Server.Transfer stops any association with the source page after the new page loads.
