I have made a registration program. Making use of mysql database. Can I still use the traditional programming for client applications. If I want to network it. Do I have to modify the codes a little in order to make it work?Do I have to install wampserver only in one computer?
View 1 RepliesI'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)

Deploying Winforms Application to Client Machines Application Failing on start
View 8 RepliesI'm developing a web application that requires the user to log in using forms authentication. inside the webpage you need to download a desktop application that requires to login to the same system too. Is there a way to transfer the current logged credentials from the web application to the windows desktop application without need to login again?. Both applications shares a Login object from an vb.net interface.I tried to save the IP address in the Database but that don't work for me because the website needs to be accessed inside and/or outside of the company and the user cannot login twice in different machines.
View 2 RepliesWe 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).

View 1 RepliesI have wrote an Application for a organisation and they had let the app run in their lan using Samba, it worked perfect. Now they want to work over the internet.The Problem is that I have written this app with Sqlite, that means its currently working so:They have a exe and the sqlite dll and the sqlite database on their samba server and they connected a network drive on their windows pc to run it. So that means every pc is writing over samba to the sqlite database.
I tried it over the internet, but like i thought sqlite is a local database and its very slow, even if the ping is under 50ms. I could create a tcp server, that handles all and writes all to the sqlite database, but I have already written around 20.000 code lines for the project, so that would be not the best option for the lazy me. I have used only one sqlite class in my client for querieng, so I thought that it could work without much work, if i would replace the sqlite database adapter with the mysql database adapter, since sqlite has nearly the same syntax then mysql.
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.
View 5 Replieshow 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.
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?
View 4 RepliesI've basically made a basic tcp server/client application. The thing is that I'm behind a router and so will be the other people that use my clients. I've had to use port-forwarding or the software "rinetd"to run quite a few applications online.
Let me explain: I'm on a lan network that connects to the internet. Whenever I want to host a server - for instance a basic ftp or http server. If I give my external IP to anyone, they won't be able to access my server. Even if I portforward, it doesnt work. I have to use rinetd here. For other applications, portforwarding works. I'm not sure how these things work at all.
Anyway, my issue now is that I have created this server/client application. I'm having serious doubts that if I run the server, I'll have to either a) portforward or use rinetd to get people to connect to my server. IF I need to portforward, that's fine. However, using rinetd would really suck... My 2nd concern is as follows: IF the person running the client is in a similar situation as me (i.e he's on a lan that has a router which connects to the net), will he have to portforward or use rinetd as well? If he portforwards that's fine. But I don't think I could get people to use rinetd.... Also, if there are more than 1 person on a lan trying to connect to my server, there is a big problem when they try to portforward: they will only be able to allocate one of their internal ip to that port, and the others won't be able to connect, right? How does this work? I mean, I use many softwares like msn/skype/(some games)/firefox that do not need portforwarding/rinetd. Yet they work. My housemates(other people on the lan) use the same softwares, and it works fine. There's no clash/probs watsoever How come these run fine?
Anyway, back to my issues. Given I have no knowledge about how the above work, I was wondering whether there was a way to host a vb .net server application on an external website (external to my house) so that I might *avoid* the above mentioned problems, and to what extent that would be a sound solution.
We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

My issue, however, is connecting to the wireless laptops as well.

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 have a client-side app which I am working on. As I start to enhance the app, I am starting to wonder whether or not I should be building a network side app instead. My app in its current form sits on the client side and generates some text and XML files which are stored locally on the client side. The user reads/write to these files. However, I want to start working with SQL AND the processing time of my app is starting to consume resources (i.e. time and CPU) on the client side.
Can someone provide me with some highl level feedback on what one would do to make their client-side app a network app that multiple users would have access to. I realize more detail would need to be provided in order to provide thorough answer. However at this point, I really just want to understand how a network app would differ from a client app from a programminga and deployment perspective.This is not necessarily a VB question. Howevever since I am working in VB I though I would start in this forum. Feel free to move to the appropriate forum if need be.
