Ok, it seems maybe I've misinterpreted how you actually should develop with TNTNET (ok, I'm a little stupid and lazy :) ).
I've made one main ECPP file, which calls functions to dynamically print data of the webpage (as you did no recommend). I.e. from main ECCP file I call TO_HTML::dayToHTML(reply.out(), sDay), where sDay is a C++ struct I loaded from the database. This function will in its turn print the the current data via reply.out() ostream (as you did not recommend). So now first I will rearrange my code with several ECPP files, so I don't need to fill up the <%args> tag with too much variables, i.e. one ECPP file for dayToHTML and so on, and see what I can make out of it and if it is working as I have planned. :) My goal is to split up the code so, for me and others, it is easy to interpret. Sorry if I may be a little severe in my explanation, it is sometimes hard to explain what you are trying to actually do. On 2015-03-07 10:58, Tommi Mäkitalo wrote: > Hi, > > Ralf is right.
