I'm interested in creating a simple localhost server that can serve dynamically generated data from a ListView into a formatted web page. I'd also like to "control" or otherwise have the program execute functions based on what links are clicked.I've been searching for solutions and it looks like it would be a fairly simple task but I'm not sure exactly what the best way to go about this would be.

Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

View 2 RepliesI have the MySQL connector dll for .net, but am having problems.
1) When I go to phpmyadmin on cpanel, it says the server is localhost. I am confused by which IP i am supposed to use to connect, as im pretty sure just localhost will not work.
2) When connected, can i use credidentials from an account already made to access the database, or do i need to use the admin credidentials?

View 1 RepliesI have an application which connects to a database, retrieves a username from a user's table and matches it against the username retrieved with System.Security.Principal.WindowsIdentity.GetCurrent.Name.On my localhost, everything works fine. The database exists on the development server but the application lies on my localhost. All of my authorization and authentication techniques are running smoothly.However, when I publish my application to the development server, I'm faced with the following error.Cannot open database requested in login 'databaseName'. Login fails.Login failed for user 'DevelopmentServerNameASPNET'.

I'm trying to see if a file I have loaded is located in the "Xampp-localhost-folder".
I'm loading a php-file-path into a textbox. After pressing a button the php file is loaded in a webbrowser. Now here's a problem. .PHP-files don't load local. The user needs to have at least Apache (MySQL/PHP/FileZilla FTP Server etc) installed so the page can be loaded via localhost.
The most important service that needs to be running is httpd.exe (Apache) or FileZillaServer.exe.

Multi-User Chat Program (Server & Client) with Main Server?
View 1 RepliesI made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.
My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?
Second question: can I make a single program where I run both TCP client and TCP server at the same time?

I am in the process of designing a computer control program to control a HF communications receiver (radio), and have found a problem with the Serial port. I am using VB Express Edition 2008. This module of the program is supposed to take an input string from another part of the program, format it, break it into 4 bytes, and send it to the radio in hex form via COM port 1. The problem comes in when you try to enter a frequency with an 8 or a 9 in it. The 8 or 9 is usually replaced by 45, ex.-input 9900, receiver tune 4545. The exact same thing happens with 8's, input 8800 and receiver tune 4545. All other numbers other than 8 or 9 work fine. The strange part of it is that sometimes the 8's and 9's work, and work correctly. For instance, 900, 1900, 2900, 3900, 4900, 5900, 6900, and 7900 all work correctly. This led me to believe that is may only be when the 8 or 9 is in the first position, but that is not the case, it also shows up in other positions as well. All other frequencies that do not have 8 or 9 in them also work. I ran into this same problem with VB Express 2005, and worked on it for weeks before giving up and going back to VB6.0. This same module (with exception of the port open command) runs flawlessly under VB6. I have even tried importing the MSCOMM control from VB6, but it gives the same results. In de-bugging mode, all of the inputs, decimal and hex seem to be correct, so the problem must come in after you click the command button, but before it leaves the COM port.
