Further information on using List & Label with ASP.NET can be found under Usage in Web Applications in chapter Programming With .NET. Of course, you can also use other programming languages for web reporting.
In general, the following requirements apply:
•The server has to be a Windows system, List & Label can only be run on Windows platforms. This restriction of course does not apply to the clients.
•If no printer driver is installed for the user account under which the web application runs, the LL_OPTION_PRINTERLESS option or (for .NET and VCL) the Printerless property of the respective component must be set to "1" or "true". Then a virtual device will be used for rendering. Note that this may have a minimal impact on the positioning of the output. In addition, it must be ensured that the user account used can load the List & Label DLLs, i.e. that rights have been assigned for the path of the DLLs.
•The actual web application carries out a silent export without user interaction (see chapter Export Without User Interaction) and directs the client to the export file e.g. by a redirect.
