Run A Program From A Network?
Apr 9, 2010
I have my program that runs from a workstation and the SQL DB is on the SERVER.I am having a lot of problem with it as the VB.NET program wont refresh the dataset.I would like to test the same by putting the SQL DB on a network drive, and run the program from another workstation.Just to narrow down the problem.My Question is this. I install the SQL DB on machine A and then install my program on Machine B?
What should I do to get Machine B to access the SQL DB on Machine A.Will sharing the SQL FOLDER be good enough for my program to access the DB of course, I have to modify the connection string on my program, but other that is there anything more to be done.

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

I have developed some programs for processing and issue-coding electronic documents. I am teaching myself how to work with SQL Server because I want these programs to work with electronic documents imported into SQL Server as opposed to messing around in a folder stuck on the desktop, for example. From there I want to expand on the program so that it is a network enabled program.

I have written small a software. I want to install it on a server and and make it accessible for all the other users on network.
How can I retrieve the server name (the computer program installed) with .NET?
Also, sharing the "Program Files" folder doesn't look like a smart idea for making the program accessible from the other computers.

I am not new to programming but have little experience and am trying to learn VB 2010.
We have HP Procurve network switches and I know that with a telnet application I can login to the switch and it will tell me which MAC address is connected to which switch port. Im trying to write a computer inventory program to track my computers and it would be really cool if I could figure out how to determine which computer is plugged into which port on the switch. Problem is that I have no idea how to go about doing that.
Is this anything anyone has tried before or does anyone know how to go about doing it?
Ive been hunting on line but havent found anything useful so far and thought Id ask here in the off chance someone knows what Im talking about.

I am playing with network sockets as I need to work on a client-server application. So I have tried this simple code from VS help:
Code:
Dim tcpClient As New TcpClient()
'The following line do not belongs to original code 'But I needed to add it as debugger told me that 'I couldnt getStream from closed sockets
tcpClient.Connect("127.0.0.1", 8000)
Dim netStream As NetworkStream = tcpClient.GetStream()
If netStream.CanWrite Then
[code]....
So, I supposed that the code above would write the message to the loopback IP (127.0.0.1), it would be kept in the network buffer and would be spited out when it readed the same loopback IP. However, when it gets the line whre it should read the stream, the program just stalls and keep reading it forever. I have tested the stream with as if it was just awaiting for something to read. I have tested the stream with getStream.DataAvailable and it returned me False, what makes me guess that the data is NOT being properly written to the IP.
Firstly I thought that it could be something with the loopback IP, then I tried to provide the machine local IP (192.168.2.25) but I got the same behavior: code stalls...

Consider a network environment with a domain and active directory setup. I would like to create a shared folder on a server for a username added by whom ever the network administrator is... I would like to install my program on a computer, but when people log into te local machine, I don't want them to have access to the shared folder, I want the program to be able to access it only, using the afore mentioned user name and password.

I'm looking for suggestions on keeping a program that is running on a network updated. Installation consists of 15 users, each have the program on their local pc, but they all access same date from sql server. I am looking for a clean method that would allow me to update one folder on the network and for each computer to get updated when they run the program and the programs sees a later ver on that folder on the network. (Obviously I can do this inside the program itself since it won't allow being overwritten while opened.)

I've made a simple knowledgebase program which contains example documents. The documents are stored in a folder, and in an accessdatabase stands the information about the documents.The program also includes a simple search option. The program itself is located in a folder on a network computer.It has to be a network program for collegues can add other examples.Now it gets weird. at least in my opinion.When I run the program locally -> no problem.When I run the program from another network PC -> no problem.But when I run the program from a network Thin Client -> shaboom..At least when I enter a search option and the connection to the database is opened:"Application attempted to perform an operation not allowed by the security pollcy. To grand this application the required permission, contact you system administrator or use the Microsoft .NET framework configuration tool."[code]Now I've found a LOT of topics in this forum and many others, and it's clear that apps from another network location are run without "full trust". And the trust issue can be handled with caspol or web.config. Although caspol is a mystery to me and web.config didn't seem to work.But since it's so explicitly crashing on Thin Clients.

I am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:
Code:
If My.Computer.Network.Ping("192.68.0.5") Then
MsgBox("Computer is on.")
Else
MsgBox("Ping request timed out.")
End If
If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:
A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll

I have created a program that allows me to remotely access computers on my network (not all done by me i found some code online) however i want to modify that program to allow me to connect to computers not on my network. How can i go about doing this? My program consists of a client and a server. When the server runs it listens for the client on the client side i enter the IP address and it connects so i can send remote commands to the remote system.

I've been having huge problems having a VB.NET Windows Forms program run as a scheduled task under XP SP3. The program runs when I set the task up to use my non-admin network username and password, I can see the interface fine (albeit without the desired results - the program requires access to remote shares). When I set the task up with the network administrator account credentials, the task is "Running" but I do not see any interface. It doesn't error - it just kind of sits there happily in the background.

In my application, the user clicks a single button and the program displays each network adapter description into a message box and then gets all the ip info for the workstation and places it into a text file and opens that text for reading. What I would really like for it to do would be to display all the network adapters into a single messagebox instead of messagebox for every adapter like it is currently doing. Here is the code I have on that button. Let me know if anyone needs more info or has any questions:

I have a program written in VB.net 2003 that are folks run under alternate credentials. Inside the app there is an option to open a UNC path to a network share. We were running Windows XP SP3 and IE6. The code is simple just a call to the explorer.exe with /root,\UNCPath. After installing IE 8 onto the machine this no longer works. Best I can tell the code is still working but now being executed in non interactive mode so nothing opens up. You can however see a new spawned explorer.exe running under the system account for each attempt at opening a UNC Path. Any ideas what IE8 could have done to cause this behavior?
