Export to HTML in stream

rbuser

Hi all,
Upgraded recently from RB7 (Delphi 7) to RB15 (Delphi XE5). I used to
export reports in HTML format to a stream using Pragnaan, I see now in
RB15 there is a ppHTMLDevice, so I was trying to use it, although I
can't find any example code, not on the rbwiki anyhow. I just followed
the pattern that the PDF and XLS devices use. Here's what I have, but I
get an error "EInOutError with message 'Unable to create Directory'
which leads me to think I don't have something set to use the stream,
although I did set the OutputStream.


lHTMLDevice:=TppHTMLDevice.Create(nil);
try
///settings
//lHTMLDevice.HTMLSettings:=ppReport1.HTMLSettings; //doesn't have
settings
lHTMLDevice.OutputStream := zStream;
lHTMLDevice.Publisher := ppReport1.Publisher;
// generate the report
ppReport1.PrintToDevices;
finally
lHTMLDevice.Free;
end;

Any idea what I'm missing?

Hi Dan,

Exporting HTML to stream is very restricted due to the fact that HTML
frequently relies on accompanying files (images, fonts, css) in order to
display correctly.

A text-only report using very standard fonts should however be able to
export to an HTML stream correctly using our HTML device. I updated the
HTML device to support this for the latest version of RB 16 in a patch.

Registered users of RB 16 can email support@digital-metaphors.com to
receive the patch.
