XML DA / OPC DA Client Development Component
XMLDA.NET is a .NET component that handles the access to OPC DA and XML DA servers. The application is coded as an XML DA web client, independent of the type of server to be accessed.

Powerful helper classes such as BrowseTree, ListBuilder and DataBind reduce the application code to a minimum. Complex data visualization applications can be implemented in a few lines of VB.Net or C# code.

The built-in service information is minimal and the OPC XML-DA specification needs to be conulted to be able to use the methods correctly.

The XML-DA client references the XMLDA.NET assembly in place of the web service reference.
Depending on the URL:
- the XML-DA server is accessed
- the call is wrapped to the OPC DA interface and the OPC DA server is accessed through DCOM.

Supports fast access to multiple OPC DA servers and standard web service access to multiple XML-DA servers.
All XmlDAClientSDK features are included.

The XMLDA.NET Wrapper is specially interesting for ASP client applications for OPC-DA servers. The ASP application is remotely accessible and may be installed at the location of the OPC-DA server. With XMLDA.NET is has direct access to the OPC-DA server without having to go through another XML serialization.
Windows Forms applications have to go through a remote XML-DA gateway to be able to access remote OPC-DA servers.
