I am developing an application on VB.NET 2010, I am planning to make an online activation system, the idea behind is that Whenever someone installs my application, the application presents user an activation form, user will be entering product key, name and email address, and then system will establish a connection to a database which contains all the keys on WEB. So how should I make an efficient program to get rid of that.
View 2 RepliesI built a window's app in VB. The app is made to be used worldwide. The app works fine when it is installed on a computer using the same network than the local machine hosting the sql database. The problem actually, is that, when the app is installed on a computer using a diferent network, the connection fails.

I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).

if user accept to update, it will download from server and install and restart application.

Question: I created an ASP.NET web application. Now it originally was meant for deployment on a webserver.That is working, so, so far so good.My question now is: Is it possible to deploy it as a desktop-application, too? That is to say the installer installs some kind of server, plus the web application, configures the server to run this application on a localhost URL, and then creates a link in the start menu/desktop, where it opens that url (website, the application) on localhost in a web browser?
I think it should be possible, though the server wouldn't be IIS, because this is a windows component which can't be separately installed. Is there anything like this already out there The nonplusultra would be that it only starts the server when you click on the shortcut.
the system is going to have two front-ends - one web application and one desktop application.The desktop application is going to be coded using VB.NET, and the web application in PHP. There's really no reason why the desktop application can't be replaced by a web application as well - except that one of the programmers seem to really want to code it in VB...However none of us have experience working with either of these pairs .
P.S. hosting service will be gotten from some provider and not be on the client's own server.

Basically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?

View 4 Replies3 years ago I developed a vb.net application that connect to sql express 2005 data base.The application worked fine.e replaced our computers, so we installed the application again. (The same exe file, the same sql server and so on).Now, only when loading few forms I receive the following message: n error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)Note that when we log in to the application, a connection is needed. The user verifying is working fine; it means that the connection is working properly.

Ok I have a question about connection string in vb.net. Im using the string [Code] but here I am specifying the serverName by its name, now if I deploy my application and send it to another person to use it I see that server name is changing according to the name of the computer. Is there any way where by I can make my application to detect itself the Name of the server present in that computer and use it in connection string?
View 2 RepliesI have a little problem with application setting in VB.net 2008. I want to switch main server and backup server connection string with combobox. [Code] It did change the Application Setting connection string in the main form when combobox1 was changed. But the problem comes, when child form was called. On the child form there is DataGridView with Dataset using application connection string. Even the Backupserver was selected on the main form, child form dataset connection string doesn't change. I don't know how to pass the current connection string to child form dataset although it is set to use application setting.

View 1 RepliesIs there anyway, in a program, to detect if a program is being run from inside a remote desktop session or if the program is being run normal in .NET 2.0? What I'm trying to do is, I create a timeclock application which will clock a person in and out and keep track. But this particular person, I suspect, is remoting into their computer at work, from home, and clocking in and out.
