View 1 Repliesi 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.

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.

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.

View 6 RepliesI 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.

View 4 RepliesI 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.
