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?
Basically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?
I have a problem I want to make a server and client where the server is password protected and will make the client display files/folders in a designated folder which will be in the server's current directory and the client will ask what IP and password to connect to and if the password is correct is allows the client to access the files/folders in that folder in C.D. of the server and the client can download any file within the folder by clicking a button, yet don't even know where to start.
i 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.
im making an application and i need to install a printer in a computer. The application im trying to do is a client-server application so the idea is that the server send the instruction to the client telling him what to do and then the client will do it, in this case it will go to a SAMBA directory and it will get the drivers for the printer model from there and after that it will install the printer, everything in silent mode.
I have a .net network application , and as part of improving the performance of the software i would like to find the shortest route to the server . When i have more than one network , i need to find the local network ip from these current ip list .
I need a program that can send and receive msgs to everyone that's on that program and on that network, then is there a way to add chat rooms to the program 2. I looked all around the Internet and MSDN and found a lot of results but non worked property.
I have created an application using Visual Basic .NET, the application use an access data base which must be shared in server of a local network. The problem is when I run the application in a client machine (connected to the network) I can't connect to the data base.In the same machine the connection work which it's not the case when I change the location of the base to: Data Source="serverIPAdress/DataBase.mdb"
I am developing an application, which hunts the local network for attached computers then checks for a share and a file, if found it displays it in a listbox. While testing this I have seen some strange Chinese or Japanese computer names pop up and in a few seconds go away, the names seem to always be different.
Here is my Prob- we have a main router from which we use a distributor or hub for internet connection distribution, ever computer connected automatically obtains IP address of format say - 180.50.50.xxx to access net connection.if any connected computer has different IP format than the given one, it cannot access internet.
I have this partially working but only shows printers for one user, need all local and network printers mapped for ALL users on a remote pc so I can migrate them, I know I need to do some sort of for each method but not sure what will work

I have developed a windows application for my company. It is a multi user software and we are using sql 2008 as the database. The sql 2008 is installed in our company server. Within our LAN, there is no problem in accessing the software and its working pretty fine.
Now the problem is, some of the managers need to go out frequently(for business tour and all) and they need access to this software. The software is already installed in their laptops.Is there any way to access the database that is in our company server ???

I am developing an application where in I need to stream audio and video in the local area network. There is calling option from my application where users can call each other(audio call or video call) in the LAN.
