Exporting Web Services (VB.Net / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\vb\VS2022\netframework\20.Reports\27.Exporting Web Services and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/vb/VS2022/netframework/Modules/20.Reports/27.Exporting Web Services
Overview
A demo that accesses the NOAA Meteorological web service and returns an Excel file with the forecast. Just in case you do not have an Internet connection available, some sample data is included to work offline too.
Concepts
How to export the data on a Web Service to Excel or PDF.

'
' General Information about an assembly is controlled through the following
' set of attributes. Change these attribute values to modify the information
' associated with an assembly.
'
<Assembly: AssemblyTitle("")>
<Assembly: AssemblyDescription("")>
<Assembly: AssemblyConfiguration("")>
<Assembly: AssemblyCompany("")>
<Assembly: AssemblyProduct("")>
<Assembly: AssemblyCopyright("(c) 2002 - 2014 TMS Software")>
<Assembly: AssemblyTrademark("")>
<Assembly: AssemblyCulture("")>
'
' Version information for an assembly consists of the following four values:
'
' Major Version
' Minor Version
' Build Number
' Revision
'
' You can specify all the values or you can default the Revision and Build Numbers
' by using the '*' as shown below:
<Assembly: AssemblyVersion("6.2.1.0")>
'
' In order to sign your assembly you must specify a key to use. Refer to the
' Microsoft .NET Framework documentation for more information on assembly signing.
'
' Use the attributes below to control which key is used for signing.
'
' Notes:
' (*) If no key is specified, the assembly is not signed.
' (*) KeyName refers to a key that has been installed in the Crypto Service
' Provider (CSP) on your machine. KeyFile refers to a file which contains
' a key.
' (*) If the KeyFile and the KeyName values are both specified, the
' following processing occurs:
' (1) If the KeyName can be found in the CSP, that key is used.
' (2) If the KeyName does not exist and the KeyFile does exist, the key
' in the KeyFile is installed into the CSP and used.
' (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
' When specifying the KeyFile, the location of the KeyFile should be
' relative to the project output directory which is
' %Project Directory%\obj\<configuration>. For example, if your KeyFile is
' located in the project directory, you would specify the AssemblyKeyFile
' attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
' (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
' documentation for more information on this.

'This program is inspired on the progam by Mikhail Arkhipov
' * at http://blogs.msdn.com/mikhailarkhipov/archive/2004/08/12/213963.aspx
' * Thanks!
'
' UPDATE: This was patched with the info on
' * http://weblogs.asp.net/jan/archive/2004/01/28/63771.aspx
' * to make it work.
' *
' * Thanks again...
' *
' * UPDATE 2!
' * The NOAA broke the service again, and it has not fixed it for more than a year.
' * I give up. We will use http://www.webservicex.net/WeatherForecast.asmx instead.
' * The code for NOAA is still there on the SetupNOAA method, just not used so you can see it (and try it if it ever starts working again)
' *
' * UPDATE 3!
' * Now WebserviceX is not working, going back to NOAA. As you can see, it isn't very trustable that a webservice will be there in the
' * future, so this demo might not work in online mode when you try it. But you can always look at in in offline mode.
' *
