Access Form Across A Network?
Apr 18, 2009
In my app, I need two separate items. I need one item to be the administration panel that can edit information being shown on a remote computer, and I also need another item that will display the information. How do I get my program to talk across a network to edit the information being shown on computer 2? I'll also need to know then how to make the installer ask which part of the program it needs to install, and then install the appropriate part.

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:

Is it possible to use a string as an array? I mean:' I have several arrays
Dim a10() As Integer = {530}
Dim a15() As Integer = {370, 231}
Dim a20() As Integer = {305, 176, 126}
'I declare a variable as a string and I assign the name of an array to it
Dim tablaalfa As String = "a10"
'I retrieve data from the array using the name of the variable instead:
lbl1.Text = tablaalfa(2)
I guess it doesn't work in this way?

I'm writing a program to examine logs of various servers on our network..they're not on our domain but i can map a drive to them by authenticating each time from my LP (which is on the domain)
my question is... how do i perform that same authentication with VB..
[Code]...
i'd like to either have a pop up box to auth as i would when i browse to the remote PC... OR be able to set it statically in the code (the servers all have the same admin login + password)

I have a .NET application (VB.NET) that runs against a MS Access database. Every data request connects to the access database, runs and returns the query and closes the connection back again. I placed the database on a windows xp 32-bit machine. I have two clients on which I installed the .NET application. Both clients are running windows 7 professional 32-bit. Now I have a performance problem with this.
When I use the first client it runs fine. All data is shown very fast. When I than use the second client, it takes some 10 seconds to connect to the database, fetch the data and close the database connection. When i ask for other data on that second client, it all runs fine, until I request data from the first client than back again. Than it takes again 10 seconds on the first client before my data is fetched.

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.

I am looking for a way to possibly intercept the point that a file is being accessed on a network share. Specifically before it is determined whether the user has access to the file or not.The goal will be to grant access to that file if the file request is coming from a specific process and that user currently does not have access.

I know my Question was asked maybe 10000 times before, but i really did not take the chance to search the forum coz i really short of time.
I have *.mdb DataBase with 20 tables each table have more than 10 fields, i'm trying to automate the MDB file from a network like that 5 PCS + One vb.net exe program (5 users) working on the same time on the exe that is connected to the database , my questions are :
1) How much risk is it to put the database into one (shared) folder and connect it to the program ?
2) What is the best way to establish this method ?
3) Is there any alternatives ?

My software handles multiple operations on files, and I have now finished writing the related functions, using the System.IO classes. I now need to add support for network drives. Using a mapping works very well (although Directory.GetFiles is a bit low, and I don't know why), but I'd now like to be able to deal directly with paths such as \192.168.0.10Shared FolderMyDrive. Is there any way to handle this type of paths other than mounting the drive to an available drive letter, using the newly generated path, and then unmounting?

I had a basic text file reader/writer program that wrote and read from a mapped, shared drive up and running for a couple weeks. I wanted to add just a couple more things that shouldn't have effected the program (the ability to write another text file), and now the program can't find the shared drive. The error I get is: Could not find file '<file location>' with <file location> filled in with either the mapped name of the drive (X:) or the unmapped name (\servercomputer). Both are copied directly from windows explorer, so I know the path is right. I'm a bit of a beginner, but I'm pretty sure that all the required permissions are in place, and all users have access to this drive.
To further complicate things, it is not consistant. Some commands appear to have no trouble reading off the mapped name, but don't read the unmapped name, and vice versa. Others won't take either. Sometimes the code will execute perfectly up to the middle of the code (accessing the shared drive a couple times), and then it will give this error. If anyone could point me in the right direction,

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 developing a Visual Basic .NET application to be used by the staff of a small training centre nearby. The front-end (UI, menus, etc.) will all be in VB .NET, and there will be a back-end database for storing all of the required data, such as student records and meeting information. What I would like to know is if it's possible to use a Microsoft Access database for this purpose, and have it accessible by all the staff in the centre (on the same network) at the same time. For example, would I be able to put the database in a shared network folder, and have a copy of the VB application on each PC that would all be able to read/edit/add to the database?

I'm trying to connect to a database on a big corperate network (access db). I can not load my application and DB on a shared network drive as it does not have the correct permissions. How else can I try connecting to a db of some sort and allow users to insert/edit/delete rows? as it's a network drive I can not install a DB such as SQL Server on it.

I have an access 2007 database that I have been developing a front end for in vb.NET for the past 3-4 weeks using vs2008 in a Windows 7 enviroment. Yesterday I started getting an error of "Your network access was interrupted. To continue close the database and then open it again." This happens in the Form Load on the line:
gotData = Me.LeaguesTableAdapter.Fill(Me.LeaguesSeasonsPlayersDataSet.Leagues)
I can go into access 2007 and view all the data fine and in vs2008 I can view the server explorer and browse the tables. However, under data sources if I try and preview the data, I get the same error message as before. What confuses me the most is that the database is not stored on a server is just stored in My Documents. It was origionally stored on my desktop pc but has been copied to the My Documents on my laptop. But as I mentioned previously it has been working fine and has just all of a sudden started throwing this exception by my Try Catch routine. FYI I have tried creating a new DB and importing the tables from the old DB but this hasn't solved the problem either.

How i can send data from one form to another form through a network? i'm not asking for the codes, i just want to know what i should do to accomplish this task. i'm conceptualizing a game with the following details:
1.) there are two players, connected through a network
2.) they take turns looking for words from a puzzle of randomized letters
3.) after the given time has elapsed their words are checked and if both players has the same word, the word is removed
4.) the score is tallied
My question is, how do i get the words from the other form? specifically, how can the server form get the words from the client form? is it possible if i use xml? or can the server form access the variables of the client form? (i don't think it can, though)

I have created multiple forms in VB.NET that need to be sent out in emergency situations. For example, the Fire form will instruct employees that they need to evacuate the building, the Tornado form will instruct employees that they need to go to the basement, etc. I have the forms created where they will display over my own computer when I run the application. I have also figured out how to get the list of computers from Active Directory. Now I am stuck. How do I make the form display on another network computer? Does anyone know how to do this?

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'm trying to setup sort of a LAN keep-alive proxy...Ex.: My Xbox 360 is connected strait to my computer via an ethernet cable. My computer is connected to the internet via a Wi-Fi adapter. Everything works fine and I can access the internet on the Xbox and computer.
Issue: Every time I start my Xbox I have to set up a "Home or Small Office Network" via the control panel to access the internet. What I would like to do is implement a proxy that when I shutdown the Xbox the LAN doesn't give the "Network Cable Unplugged" notification. I wasn't sure if there was a way to make the connection stay open for so long after it should say unplugged. Such as if I need to restart the system and don't want to have to re-setup the network on the computer.
This is my code to retrieve the network info:
Imports System.Net
Imports System.Net.NetworkInformation
Module Module1
