On a lan, the server and multiple clients work correctly.but over the internet, the server and client can't hear each other(we tried several different host computers, and several different hardware configurations)Is there a secret to getting UDP to do connections over The Internet vs a LAN?
View 9 RepliesI have a small web browser application I wrote in VB.NET that is specific to it's use. To set it up, I have to setup port forwarding. Is there any way I can write another .NET app that runs on my dedicated server, accepts an incoming connection from my home PC that sits there. Then any other incoming connection from the outside world can then be connected to my home pc through the app on the dedicated server? If there is a term for this sort of process or program, I do not know what it is.

Using VB.Net and SQL Server 2008 R2: I have recently had a database that using sp_who2 reflects a connection ".Net SqlClient Data Provider" is still active even though the .Net application has closed and disposed of all connections.

In my application, users can establish connections to one or more databases in order to pull in data, thus a read-only connection is sufficient. I use the following connection string syntax when connecting to an Excel 2010 database:

I'm pretty new to VB.NET and connecting to SQL Server.What is considered best practice when building an app that needs to connect frequently to a SQL Server DB to fetch, write, delete and update records?Should a connection be opened at app startup (a connection at start is opened to validate the user) and left open for subsequent transactions or should a connection be opened, closed and disposed of each time a read/write to the DB is required?
View 3 RepliesI have written a program that uses directshowlib to capture a stream from a webcam and save as an AVI whenever a bird lands on the experiment platform for behavioral research. What I would like is to be able to allow another program or connection to the same webcam at the same time simply for preview purposes, is this possible?
Basically I want my app to still be able to record on demand when a bird interacts but I would also like a IP cam program like webcamXP/Webcam7 to be able to stream a live feed to the internet so we can have a live view of the platform. I had found some articles about connecting multiple streams from one webcam but am not sure how to go about it. If I have to I will simply mount a 2nd cam in the Bird colony and dedicate it to the web stream but if I can use the same cam as the recording cam that would be great.

I'm planning on a very basic game created in VB.Net WinForms and a web server(shared) which will host PHP and MySQL.I think, I can create this basic game with no problems. But my headache is with the communication part In the db(MySQL db in the web server), there'll be usernames and password listed in a table. When my vb app is opened, it would ask for the username and password. The user enters his username and password. This data is compared with the data in the db. If a match is found, then the game starts and the user can play the game. At the end of game, it will ask for the confirmation to send highscores to the webserver. When confirmed by the user, the highscore will be send to the webserver, which will be then stored in the MySQL db.
The game will be a simple one just like Tic-Tac-Toe or a text based game.What all things do you recommend for the development/communication part of this game ?
Is it even possible to run an exe file in e.g. i.e. ? How to translate it to html code? The program is an agenda and has monthcalendars and datetimepickers.

Since in South Africa Internet is One of the many things that are way overpriced I want to monitor each computers traffic with a small Program since even when we are not at home for a day we might easily use 2 gigs of data. Somewhere a computer is downloading like mad?For a 4 mib(you only get 3.5 at most) line here Will cost you around R413(36 GBP/ 58 Usd) per month and One gig of data around R19(1.68 GBP/ 2.70 Usd) - R112(9.9 GBP - 15 USD).Ok enough Complaining. Each Computer in our house Connects to the internet either with lan or Wlan So is their a way to get how much traffic passes through one of those OR is there a way to monitor the total internet traffic regardless of how it connects to the internet ?
View 3 RepliesAlright everyone, this is a huge problem I've been having for a while. How exactly would I go about refreshing the internet settings so that a webbrowser will check the registry again for the IP to use? Instead of just using the IP that's there when the browser is first instantiated. Here's what I'm looking for that someone else directed me to, however it's in C#. I'm sure there's a method like this in VB.NET, however I have no idea what it may be.[URL]..
View 8 Replies had 3 courses in computer science 10 years ago and decided to go into economics. After a 6 year and continuing career in economics, I decided to dabble in code to assist my economic career. In this pursuit, I have developed some neat things, but I have a simple problem. I code an application, hit build, hit publish, receive a setup and manifest, then put it on my usb drive. Plug the usb drive into another computer. Drag the setup and manifest to the hard drive, hit the button, a graphic regarding Launching Application comes up, then immediately a window comes up stating:
Cannot Start Application.Cannot download the application. The application is missing required files. Contact application vendor for assistance.
The errors stem from the manifest file. It says downloading the file (file path) Hello.exe.manifest did not succeed. It then follows with 3 lines of filepaths for the Hello.exe.manifest.
I am running VB 2010 express. I made a slot machine game for my mother for her birthday one Computer A. I moved the published files to Computer B as described above to test before giving to my mother. The game isn't too important at this point because I tried to test whether the game itself was the problem or if it was my error in lack of knowledge of how to deploy. As such, I created a program called Hello. In Hello, there is simply a form1 and a button1. When clicked, button1 displays a messagebox with some text. Not a rocket science program.
My intention is simply this:Allow the Hello program to be put on another computer via a USB drive and then installed.The two computers are not networked and let's assume the second computer cannot connect to the internet. When I go to the wizard, I select the location I want to publish to. In this situation, my desktop.Next, I select CD-ROM/DVD-ROM instead of UNC path or website. I don't know what UNC path is. I presume CD-ROM/DVD-ROM would be similar to USB drive in that it is a removal data storage item.I chose that the application will NOT check for updates.Finally, I receive this:The application will be published to:
file:///C:/Users/ComputerA/Desktop/
Where I find the files, put them on the USB drive and try to install on Computer B.Also, for more information, I can use those files on the originating computer and they do SUCCESSFULLY install and I can use the application. I have not figured out why it will not install on another computer.
I am in need of a method that will clear all of Internet Explorer's cookies.

we have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.
