I am developing a system where multiple client apps are going to communicate with a server app. I will probably use TCPIP classes to facilitate the communication.
However, is there a way that a client install can automatically discover the location of the server software on another machine?
I have VSTO Excel addins (.net 3.5) and need to know when the Excel wookbook is being opened in a Browser rather than the Excel client. I haven't figured out a way to do this nor found a solution online and I suspect I am just not using the right seach words. Does anyone know how to do this?
View 2 RepliesI'm making a little application in visual studio which loads a ROM in an emulator. I have two emulators and 20 ROMs.I made a form and added a few buttons. When you click the Button it opens a new form and closes the old one. Then on the new form I have four buttons: each one loads a different ROM in an emulator. So when you press Button1 this code is triggered:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles yellow.Click
Shell("C:UsersshiftyDesktoppokemon gamesEmulatorVBAVisualBoyAdvance.exe ""C:UsersshiftyDesktoppokemon gamesRomsYellowPokemon Yellow.gb""", vbNormalFocus)
End Sub
It works fine - I click it and it loads the game in the emulator. The bit im having trouble with is the file paths. If I send this application to a friend, it would still look for "C:UsersshiftyDesktop" - but that's on my computer, not his.Is there a way to make the application look for the file on his computer (without changing the file path to (C:Users""his user name""Desktop))
I am trying to make a program that is able to find out where it has been saved on the computer, and take that directory and save the output of the program, which is a text file, to the same folder that it is in.
I have already made it so that I can type in the directory in my code, but i want it to be more adaptable.
how can i Discover a Window Class Name ?
View 3 RepliesHere 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 would like to create my own application that will simply discover the wireless networks in the area, similar to how the wireless card software works. I don't really know where to start, except with maybe the System.Net namespace.
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.
