I suppose you already have a tag=value list, with the values already converted to string, so you should have a look how the AnswerPage function works, and create your own Answer method. Probably have your tag=value list implemented already in TStringIndex, and call the HtmlPageProducerFromMemory directly. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

I try to provide a function where I can define a page with tags w/o prior knowledge of number and names of the tags. The application can hold 1, 10, 100... variables. The definition (number and names) of the variables is defined by the user, hence known at runtime, so the user can define his own template with the tags he is interested in. The template is used when creating the virtual document. At runtime, the application knows both the name and the value of all variables, all of them go into the definition of the tags when creating the virtual document and are thus available if defined in the template or not.

[twsocket] Error when building an answer page
Hi, I am trying to create a virtual document where also the number and names of the tags can vary at runtime. When I build the answer page with a fixed number of tag like this: ClientCnx.AnswerPage(Flags, '', '', 'Status.html', nil, ['Date', DateToStr(Date), 'Time', TimeToStr(Time)]); Everything works nicely. However, when I try to build the tags dynamically at runtime as string or stringlist, a page saying "Odd number of tags for substitution" gets returned. Is it at all possible what I try to do? If so, what am I doing wrong?
