.net - Creating A Program That Runs As A Service And Submits A State To A Database (over The Internet)?

Dec 2, 2011

What I am looking to do is write a VB.NET program, as a service that reports anything on client1 that I want (say the fact it is online) to a database on the internet, so I can look on management1 and see the online status of the machine (assuming management1 has a connection to the online database).

What is being reported doesn't matter, what I am looking at is a starting point to create a system like that. I have googled obviously and come up with nothing, I'd just like a "starting point" or some documentation to look at for creating something like this. The service doesn't look too difficult but the periodic reporting of online status or ANYTHING to any kind of database is not something I am sure how to deal with.

I already have setup a VBS that reports information to an ASP script that then places it in a database but I don't know how I would create say a "keep alive" connection for a vb.net service.

Form Submits Data To Database Instead Of Cancelling

Oct 2, 2011

I'm working on this form, and I got 1 text field I am using for validation. If the user doesn't put text inside the box and he clicks the save button it throws a messagebox saying that he didn't put text inside the box, but it still saves the data to the database anyways.

If txtUsername.Text = vbNullString Then
MsgBox("All Fields are Required!!")

Forms :: Get The Message That The Local Database Is Empty But The Program Still Runs?

Dec 27, 2011

I'm having an issue with the startup of my build app with vb2010.Let me explain what the situation is at the moment.

I have a form and a splashscreen. I use the application events (startup event) to check if there is a network connection, if so the splashscreen will run and it will check if the database is available, if this is the case, it will copy the online database to the local ms access database.If the startup check of the network is false, it the user gets a message that there isn't any network available and the program will try to run normal, then when the user clicks the ok button of that message, it will check if the local database has any records. If so the splashscreen will run and the program starts normal (without copy the database, because there isn't any network available).The issue that I am having is, that when there isn't a network connection and the local database is empty, (I do get the message that the local database is empty), but the program still runs, while it should exit.Here is the code of the application event:

Protected Overrides Function OnInitialize(commandLineArgs As System.Collections.ObjectModel.ReadOnlyCollection(Of String)) As Boolean
Me.MinimumSplashScreenDisplayTime = 5000[code]......

Created A Service Which Runs Fine On Development PC?

Mar 10, 2009

I have created a service which runs fine on my development PC. It reads XML files data into and Access database. Any errors that might occur are wrote to an eventlog. Like I said all of this works fine on my development PC. I have copied the service EXE on to another PC and run the install and that all works but when the service is fired I get a .Net 2.0 error - system.argumentexception error. I put a delete temp file line of code in to see where the error was occuring and it seems to be when I try to open my database.

Do I need to create a deploy for my service?

Program Closes But Still Runs In Processes?

Apr 8, 2011

I have made a program that has an intro screen, moving onto an activity select screen which acts as the main interface to get around the program. After creating the program and installing it on my computer, when I close the program from the activity select screen, using the "X" at the top right corner, the program continues to run under "processes" in the task manager.If I close the program from the intro screen though, it will close everything, including the processes. Is there anyway I can get the same to happen with the game select screen? I can make it work by putting my own "End" button on the form, but id prefer to be able to do it with forms own close button.

I created a program in MS Visual Web Developer 2010. It has a form that simply launches a script that manipulates a database. The project lives in several files and they are all inherited so they see each other and it accesses a MSSQL Express DB on one of our servers.
