I have a program that I have written using 2005 and .Net Framework 2 SP2. I went ahead and created the snk file placed it in a shared folder on the same server that I will be running the app from. In my AssemblyInfo file I added point to where the snk file is located as follows.

These are two code blocks from the two programs I have wrote. The first is the server program that receives a connection and writes the file to disk. The second is the Client program that sends the file to the server to be written to disk.As it is - it hangs. I did once get it to write to the disk - but the file was twice the size of the original. what objects to use for transferring a file over a TCP IP network connection with TCPClient and TCPListener.
I am unable to run batch file that is located in mapped network drive using System.Diagnostics.Process in VB.Net. I get:'<batchfilename>.bat' is not recognized as an internal or external command, operable program or batch file.Press any key to continue..I get the same error when navigate to the folder (using explorer) that contains this batch file and double click it. I can successfully run the batch file by changing the directory to that folder through command prompt. I can't figure out why this is happening. I think the problem is Start() function of Process works like double click rather than just run the batch file.

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:

View 2 RepliesI 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 writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).
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 want to use my SQL Server DB over a network. I have setup server client applications.The thing is for my current DB, I need to give it to server administrator who attaches the DB to SQLExpress instance and only then my network computers can access that.My question is, is there any way that my vb.net application could attach this DB through code at runtime, and DB gets all rights that are necessary to access it over the network?
I can attach DB using Create procedure but for this I need to know the sa password. Is there any way that I could achieve the same goal without sa passord and sa intervention?My only purpose is to enable my DB to be accessible over the network with all read /Write rights.

It's quite out dated but I just need it for a quick project. I need the client to auto-connect. This program will be running on the LAN only, is there a way to find on what computer the server is running on (i.e. all computers hosting the specific server on port x). I've seen it on a couple of games that run on LAN. Without access to the internet, they manage to display all available games on the local LAN. I'm doing this with VB.net.

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.
