How I wrote, I've googled with different search words (since days). I don't find any website where I see an explanation, how to do it or see an example.
For example
unigui TUniUrlFrame PDF send to server
unigui TUniUrlFrame get changed PDF
and so on.
The first problem is, how can I get the changed PDF on Client side? I have no idea and google has no answer for me. The last hope was, that the experts of unigui has a solution. I mean, other content of fields like uniDBEdit are also send back to the server and saved in the db. But how is the trick? I can't see it, what is unigui doing.
Best wishes
