I am leaning a lot and this is exciting stuff!
In infopath, I want to display a list box which values are populated by a
web service.
<WebMethod(Description:="This function provides you will all the news
release years we have")> Public Function NewsGetdates() As String

Question:
What type of data should I return from the web service? Should I return a
recordset ? What type of record set -
The data comes from a sqldatareader....
Dim stuff As SqlDataReader
stuff = cmd.ExecuteReader()
While stuff.Read
DatesSelectbox = DatesSelectbox & "<option value=" & stuff("year") & ">" &
stuff("year") & "</option>"
End While
NewsGetDates = DateSelectbox

This of course wont work because the list box does not understand <option
value, etc...

Thanks

Terry

Hi Terry,

You will need to return a "dataset" for InfoPath to consume this data. Here
are some links that may be of benefit:

service in InfoPath 2003
http://support.microsoft.com/default.aspx?scid=kb;EN-US;826994

Here is a VB.NET sample web method for returning the Company names from the
Customers table in the Northwind sample database:

<WebMethod()> _
Public Function ListCustomers() As DataSet
Dim da As New SqlDataAdapter("SELECT CustomerID, CompanyName FROM
Customers", con)
Dim dsCustomersOnly As New DataSet
da.Fill(dsCustomersOnly, "Customers")
Return dsCustomersOnly
End Function

I hope this helps!

thanks scott:
so this should work...?
<WebMethod(Description:="This function provides you will all the news
release years we have as a dataset")> Public Function NewsGetdatesDataset()
As DataSet
Dim MyInternals As New Internals
Return MyInternals.GetDatasetdates()
End Function

Public Function GetDatasetdates() As DataSet

Dim cn As New SqlConnection(MyConnectionString)
cn.Open()
Dim cmd As New SqlCommand("Sproc_NEWSRELEASES", cn)
cmd.CommandType = CommandType.StoredProcedure
Dim adapt As New SqlDataAdapter(cmd)
adapt.Fill(GetDatasetdates, "year")
cn.Close()
cn = Nothing
cmd = Nothing
MyConnectionString = Nothing
Return GetDatasetdates()

End Function

Hi Terry,

I have not specifically tested in the manner you describe but it seems as
though it should work.
