VS 2008 Connect To Database From A Service?
Nov 20, 2009
I am developing an applikation that uses an access database for storing records. The form app is for the users to add and change data in the database and so on.
but then I should have a service to cycle thru the database to check some criterias and so on to trigger events etc. No problem with the service part, found this articel [URL]... With the form application i have no problem to connect to a database and manupulate the records etc..In the service app i have to manualy code the connection to the database. Does someone have a tutorial or could help me with some examples code for manualy connect and move in a table?

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I would like to know how could i connect my Visual Basic program to a database that can be opened to MS Access. My friend made a program that links to a database that opens in MS Access and when you open the database the inputted data are organized to their respective columns and rows. However he used VB6 in making the program and he wont let me see the syntax. And another thing, the program that he made updates the database everytime a new set of data is inputted.

i have a form with a bunch of textbox's that are connected to a ms access data source, so i can update, edit and delete records.I also have 4 radio buttons.What i'm trying to acheive is that when a row is selected in the datagridview, the textboxes show the values in them (id, name, number, etc.),which works perfectly, and the radio buttons should show the value of the "grade" column of the cell that is selected.
So basicaly when you click a record, if the grade is 5 i want the radiobutton5 to be selected. And if i click radiobutton6 it should update the field to 6.

I am using VB 2008 express and SQL Server 2008 express on a test basis and I used to connect VB express to a SQL database (created in SQL Server 2008 Express management studio) file and it work perfectly until my hard drive packed up and I had to get a new one, so I had to reinstall both of these again and copied my old databases from a backup I had. Now when I try to connect to the database file it cannot connect. Network related error or the instance name is incorrect. When I look at the advanced options in the connect dialog it shows my instance as .SQLExpress and my correct instance name is .SQL2008Express. I clicked OK on the connect dialog and manually changed my connection string to the correct instance and that worked but whenever I run the application in debug mode it give me the same error as above.

I added a new database using SQL Server Management studio express 2008. I can connect to that database using Web Developer and Visual Studio just fine. But when I try to connect from VB Express 2008 I get an error message "file in use by another program". VB only prompts me for the name of the database, but Web Developer and Visual Studio prompts me for both server instance and database name. I'm sure this is just something simple I'm missing.

I have a VB.Net application that must connect to online MySql database.I already have a MySql database and I connected to it from VB.net using the MySql connector (new instance and direct connect).All I want to do is to connect to this database via a PHP web service, this will make a fast connection and more users can be connected at the same time.I tried to search for this, and I think that the solution is easy and simple, but I don't know a lot about PHP; how to upload files and connect via Web service Reference in VB.net.I downloaded these files: RemoteMySQLDatasetWS.zip And RemoteMySQLTest.zip. from: http:code.google.c.../downloads/list. which contains ".php" / ".wsdl" / ".dll" files and a VB.Net test solution.I uploaded the files (".php" / ".wsdl" / ".dll") to the FTP manager in the cPanel where I created the database. The problem is, First: I don't know if these files are working.Second: if they are working, I don't know how to accesss these file via HTTP, so I can add the "server.php" address as a web service reference in VB.Net.

First off, my apologies for being a complete Newb! I have a SQL Express database that I use quite successfully to track my investments in several accounts. I built it myself, it's quite functional, and Im happy with it. The problem is that there are multiple account tables and updating them can be tedious in SQL Server, if multiple purchases and sales in multiple accounts have occurred in a month. Tedium can lead to errors¦

So, what I'm trying to do is to connect to a remote database using the MySQL connector. Dim c As New MySqlConnection c.ConnectionString = "Server=" & URL & ";Database=" & "" & ";Uid=root" & ";password =" & "" c.Open()I know the connection string is correct. I can access the phpMyAdmin through a web-browser just fine. For some reason however trying to open the connection throws an exception 'Unable to connect to any of the specified MySQL hosts'. I tried disabling the VS debugging process, as I thought maybe it's blocking my MySQL access for some reason, but no.

I have written two functional identical vb.net applications: one runs as a Windows Form Application, the other as a Windows Service (LOCAL SERVICE). Associated with each of these applications is a MSACCESS Database that is read by and written to by each of the above mentioned applications. This MSACCESS DB has two local tables and two linked (Oracle) tables. Connection to this database employs the oledb object for the connection and dbAdapter (code segment included below).When the Windows Form Application runs, all is well.I am able to read from both the local MSACCESS tables and from the MSACCESS Linked Oracle tables. However when I try to do the exact same reads using the Windows Service (LOCAL Service), I am able to read the MSACESS local tables but I am not able to read the MSACCESS Linked Oracle tables. The error trace is as follows:
System.Data.OleDb.OleDbException: ODBC--connection to '{Oracle in Ora92}WILLOW1.AM.CPCHEM.NET' failed.
at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr)
