View 7 Repliesi have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.
What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.
I need to copy a file from a local computer to a remote computer on the network, if i try to use File.Copy without logon i get the following error:"Logon failure: unknown user name or bad password."How do I provide user name and password for file copy?

View 5 RepliesI have an application that automatically updates addins for excel from the server to all the computers on our network. right now all i get is an error if excel is open, but what I want to be able to do is check if excel is open on each computer first and give the user a chance to save their current work then close excel. otherwise i cannot update their addins if excel is open.
View 3 RepliesSince it will be run by the user I don't want the user to have to do anything but send the IT department the log file it creates.
What I want to do is see if a folder on the network can be opened successfully. I do not want to ping it, but actually open it and see if it loads. I can do this for a website by retrieving the http status code, but I can't find any references to something similar for explorer.exe. Here is a basic flowchart of this part of the program:
ping server --yes--> access \server_namefolder
--no--> access \server_IPfolder
--no--> Authentication Issue
--yes--> DNS Issue
Note also that just checking authentication won't work because it could also be a DNS problem. I guess I could check them both, but I would rather do it this way if possible (and I don't know how to go about checking either one)

I am creating a project with VB2008 Express Edition. The end result will be a CD containing tech manuals in pdf format which will be accessed via various buttons on a form. I am going to include Acrobat Reader Redisributable on the CD which the user can install by pressing a button on the form if required. What I want to do is this:- When the user inserts the CD into the PC, the form will load.When the form loads, I want to search the users PC to determine if Acrobat Reader is installed.If the Acrobat Reader program is not found on the system, then display a MessageBox to inform the user to install the reader from the CD.Would this involve searching the users registry? I would need to insert in my Form1_Load sectionTarget systems would be Windows XP/ Vista with programs on the C: drive as default.
View 4 RepliesI have a computer that takes in a barcode through a Visual Basic program on one computer and I want to be able to compare that barcode as a String to data on a different computer on the same network by ethernet connection where the data is stored in an Excel 2010 file (.xlsm) in Column A in a workbook called 'Data.xlsm'. Before the data is allowed to be saved or used further in the program on the first computer, I would like for the comparison to happen.
Some more details that you all may or may not need.
Computer 1 (where barcode is scanned): Windows 7, Office 2010

This code is put within a timer that executes every 3 seconds. ( instead of a while loop ) Whenever I run this code, the program takes time to upload the files in the folder to the ftp server, and it becomes (not responding), but it doesn't stop working, after the "not reponding" message, it reponds, but then it becomes not responding.. this is making the uploading process very Slow. I've heard so many things about application.doevents() and Threading and etc.

I'm trying to download a file from the internet by clicking a button in MS Access.
I'm trying to use My.Computer.Network.DownloadFile as described here: [URL]
Private Sub Command2_Click()
My.Computer.Network.DownloadFile("http://www.example.com/temp/xml_test.xml", "C:xml_test.xml")
End Sub
but the 'Microsoft Visual Basic for Applications' IDE that I'm typing this into seems to have no idea what I'm talking about (text just turns red).
Can I just not do this through the built in VB editor or can I simply load a library or something to make it work?
Sorry but I'm very new to VB and to Access so search results are not specific enough for me to understand - lord knows I've tried.
I'm using Access 2010 but the DB was created in an previous version - not sure if that matters.

View 2 RepliesI have a problem when trying to detect the computers network connection status.
Here is the code I have used:
Dim IsAvalible As String = My.Computer.Network.IsAvailable

Label1.Text = "Disconnected"</code></code>
End If [/ICODE] End If[/ICODE]
But for some even when the network is disconnected or the computers wifi is turned on I still get the result of "Connected". I think there something wrong with the code.
