VS 2008 - Networked (or Connected) Multiple Programs
Jul 27, 2009
I'm planning to make multiple projects, which could connect (or comminicate) together. It's like a designing Network Program. There'll be a main program and some sub programs. These sub programs will send the informations about other computers which is on my network to the main program. If you ask "Why do you need to get infos about other computers?" ,then let me explain. I'm using limited internet connection and I'm not the only one who's using this wireless network. If I get over the limit, I'm paying some limit-upper fee. So, I've to control others internet usage to not to get over the limit. I've just made a small download counter program for my pc, but as I said, I want to convert it to a bigger project, with network solution. Could anyone refer me any resource, or show me any starting point?

I have an application whereby several people in my office will use it for a number of duties we are all on the same network but everyone will not be logged in at one time.I want to enable the tcpclient class I guess as I want one user to be able to send another user a message etc.The problem is I don't have a central server where I can keep the internal IP of each user is is logged in etc. is there a way around this?

I currently have one VB 2010 express program that runs on my machine,It tracks machine run-times so I can't shut it down. The problem is now I have a new project to write and when I go to debug it, the currently running program pops up and I cannot debug the new project. Is there something I am doing wrong, or does the VB express environment prevent more than one instance of the runtimes from running?

In the past few weeks, to speed up our database freshening process, I've created a couple of extra programs, basically copies of the exe file. The program itself, accesses web pages, images etc and uses threads to do so. The second program uses LIMIT 300,100 and the third LIMIT 600,100, to make sure they don't work on the same records.
Before the last few weeks, one occurrence of the program used to run without problem, from the task scheduler all through the day. Only one occurrence of each exe can run at a time.Since theres now three programs running, .net 2.0, on xp, the program often seems to get stuck and never ends. I have to kill it from task manager.
It runs fine in the IDE I just wonder if there would be any benefit from upgrading to vb.net 2010 ?

Since ADO.Net uses a 'disconnected' model where the data available to a single program is just a copy of what is in the database, what is the normal way to handle multiple programs needing to update the same table in a database? The problem I see is that a program can't update unless his copy of the data is the most up-to-date. Are we supposed to read before updating and hope that the update occurs before someone else changes the data?

I have a program that, at present, reads a set of global variables from a text file. The program is on the client machines (around 100 clients). My problem is that when it comes to the update of the variables within the client program an error sometimes appears stating that the text file could not be read as it is already open (by one of the other machines). Currently I am cutting it down so that only 30 machines read from the single text file, although I am still going to get the error occasionally. Any ideas (apart from catching the error, and trying to read again until it works). Maybe another way to store the variables?

On my program I am trying to make a ToolStripStatusLabel's text change to "connected" if connected to a network and if not connected to a network change the text to " Not Connected" then I don't know how to display a image if connected to a network or not connected. So if the computer is connected to a network I have a image that I would like to be displayed next to the ToolStripStatusLabel. And if not connected to a network, can the program display a different image? I tried this:
My.Computer.Network.IsAvailable=True(ToolStripStatusLabel2.Text "Connected")
My.Computer.Network.IsAvailable=False(ToolStripStatusLabel2.Text "Not Connected")

We have around 2000 staff. Each has a shared drive to store some of their files. This shared drive points to a central location on our network.[code]...
Each user will have a folder within the root "ournetwork" labeled with their username. I do not have to worry about the directory creation as that's already done for me. These users are all tied into our AD for authentication. Folder name == AD username.
We would like the ability to allow our users to access their mapped "F" drive from outside our network through a web page. I understand that the programming involved (assuming it comes to that) will not rely on their mapped drive but rather the UNC path as posted above.
I am open to suggestions on how to get this accomplished. ASP.NET? Is there just an IIS solution like WebDAV? (although client-side WebDAV on win 7 seems to be broken, so that may be off the table).

I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

I am a beginner to network programming. I am trying to make an application in vb.net 2008 where in I can open a file from the client computer, do some changes to it and save it back. How should I go ahead with it and what will be the best way to do the same.

I'm working on a windows forms application and would like to incorporate a feature that would allow me to pull the video stream from a networked DVR source. I have an existing desktop program that I may be able to use to snoop out some of the protocols used, but I have absolutely no idea where to look for a library or api to actually display the video.
Has anyone successfully done this? (Connected to a remote DVR, played realtime video in their own application)

how I should go about getting the names of the computers on a network. And if the comp had file sharing on, get the "tree" of dirs on the computer. Would I need to authenticate myself in order to read/write actual files to it?
how to even get started, so I don't have any code - the best thing I can think about doing is getting the tree of "\\network" or something. (forgot what it was called)
find some code (or give some search keywords or names of APIs) that would allow me to see and write/create files on a networked comp.

My issue, however, is connecting to the wireless laptops as well.
[code...]
I need to grab a list of all networked computers, and I definitely include systems on the wireless
network in that list. I'm just not sure how to approach this. Being able to enumerate through a
'tree' of all networks and systems available would be a major plus.

I started with VB 6.0 back when i was 14, I was mostly into coding programs that interacted with other programs. Recently I installed VB.net 2005 pro i got from school, and i grabbed few source codes that teach show interaction, I feel so dumb, i dont remember anything lol. It be great if you guys can share some source codes and other stuff in this field. also other day i was in dream spark and i am able to get copy of VS.net 2010 ultimate edition, are there a lot of major changes, cause i got 2 thick book for VB.net 2005..

When you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.

I'm not sure if this would be this right place to post this, or even if I should go about trying to do it through my program itself or through the computer's settings on the final EXE file, but anyways, here goes.
I have a synchronization program that syncs my flashdrive to my home computer and (hopefully) my flashdrive to my personal folder on the school computers. What I think would be easiest, though, would be if the program was located on the flashdrive, and would simply "autorun" when I plug it in, instead of having 2 separate instances of the sync program running at school and at home.
Would it be easier (or possible) to code for that from within the program, or with the EXE file's settings?

I have a Windows Form Application which has been developed in vb.net 3.5. It is a charting program and shows stock market charts to users. Now I have made another program in vb.net (same .net version) and I want this program to interact with the one I made before. The new program is like a small scripting language. So for example: if I run a script then its output should be reflected in the other program. How can the two programs communicate ? Both will be running on same systems. No remote stuff. I mean passing arrays,strings or possibly structures.
Plus I have several functions which are written in first program. Is it possible for the other program which is an .exe also to call the functions of the other one if I make sub/function public or something. The reason is we can calls functions or subs if we include a dll. But can one exe calls functions/sub of another exe (if both program are in .net).

the only way I can get reading from an instrument is through proprietary software. even though it is connected with USB. the instrument - a Cary 500, with a GPIB interface.the problem is with instrument commands, like "reset" or "change wavelength" or "instrument reading" They reside inside a primitive Basic shell provided by the instrument software. I'm looking at expencive National Instruments, is there another solution with VS/NET?
