C# vs VB Confusion

Asked By: Carolyn Gardner Date: Jan 28, 2006 Category: Sharepoint Views: 250

The MSDN example for writing SharePoint Web Services is here:

msdn.microsoft.com/.../en-
us/odc_sp2003_ta/html/odc_writingcustomwebservicesforsppt.asp

And I'm at the point where I'm trying to code the button to execute
the "Hello World" service and it's written in C#

And, of course, I've gotten this far in VB

The code looks like this in C#

WSSServer.Service1 _svc = new WSSServer.Service1();
//to use the following line use System.Net in the using section
_svc.Credentials = CredentialCache.DefaultCredentials;
string _Retval = _svc.HelloWorld();
MessageBox.Show(_Retval);

Any chance any of you guys could return the same code in VB?

Try this, it's usually pretty accurate:
carlosag.net/Tools/CodeTranslator/Default.aspx

Or you can try the Visual Studio Add-In "Paste As VB":
msdn.microsoft.com/msdnmag/issues/06/02/PasteAs/

Visual Studio is having trouble with the first line:

WSSServer.Service1 _svc = new WSSServer.Service1();

It doesn't like the WSSServer object. It says:

Error 1: The type or namespace name 'WSSServer' could not be found
(are you missing a using directive or an assembly reference?)

Unless I'm mistaken, which is entirely possible, WSServer refers to your VB.NET web service's default namespace... Perhaps you named your VB.NET project WSServer?

To my knowledge, there is no class in the Microsoft.SharePoint namespace named WSServer.

Any ides what msdn is trying to make me do?

I'm on this page about 2/3 of the way down:

msdn.microsoft.com/.../en-
us/odc_sp2003_ta/html/odc_writingcustomwebservicesforsppt.asp

The heading is "Using the web service"

Is it just me or could a "hello world" demo be a little less
difficult?

This describes how to reference the web service you created in the previous step, you'll need to substitute your server/project names for what they used in their demo to match what you created.

To use the custom Web Service

On another computer, open Visual Studio .NET.
On the File menu, point to New, and then click Project.
In the Project Types box, select Visual Basic Projects or Visual C Projects, depending on which language you prefer.
In the Templates box, select Windows Application.
Specify a name and path for the project, and then click OK.
On the default form, add a command button to invoke the new Web service.
Add a Web reference to the Web service:
Right-click the project, and then click Add Web Reference.
In the wizard, type the following URL, and then click Open to download the service contract for the Web service:
http://Server_name/_vti_bin/Service1.asmx
Name this reference WSSServer.

This WSSServer is the object reference (web service reference) that you are missing in your client code that accesses it.

Exactly. I had butchered the web reference in my third try before I
realized I had a typo in the web method.
