RE: reading pdf/html from ifs send via cgidev2 -- RPG400-L

You can force the browser to download the file with the
content-disposition HTTP header (I don't think there's anyway to do this
with JavaScript). Take a look in the WEB-400 archives for an example.

Jim,

I'm not sure, I've never tried it.  opening a .csv or .xls in IE
actually opens excel in the browser, so I'm pretty sure it would work
the same way using the technique below.  once in the browser, the user
could choose 'file/save' to save a copy locally.

Scott says you don't have to create the data as a file on the IFS, and
instead send it directly to the browser, but I don't know how to do
that.  if you go in this direction, be sure to read his critiques
about duplicate file names, IFS clean up, etc.

Thanks again

Yes we intend to have the option to send html/pdf and probably xls

back to

the user. The tool will allow us to create them easily from either a

spool

file or an sql statement.  We (or the user in some cases) will be able

to

request what the return output will be.

Can code similar to that below also be used to return an excel file?

FYI, for the code below, the standard out to the browser looks like

this:


Content-Type:  Text/HTML
Pragma: no-cache'
Expires: 0
Cache-Control: no-cache

<html><script language=JavaScript>
var pdfWindow =

window.open("//webdirectory/pdfs/mypdffilename.pdf","pdfWindow","scrollb
ars,

resizable,width=750,height=540");
pdfWindow;
pdfWindow.moveTo(3,3);
history.back();
</script></html>

I'm not very well versed in how cgidev2 works (just played briefly

If you can already create the PDF and can give it a unique name via
the CGI program, the program can tell the browser to open the pdf in

separate window by pushing the following code back to the browser

via

std out - (this is the only reply the browser receives from the CGI
report request):

C                   eval      OutStr = 'Content-Type:  Text/HTML' +
C                              $CrLf + 'Pragma: no-cache'         +
C                              $CrLf + 'Expires: 0'               +
C                              $CrLf + 'Cache-Control: no-cache'  +
C                              $CrLf + $CrLf                      +
C                              '<html><script language=JavaScript>'

C                              $CrLf +
C                              'var pdfWindow = window.open("' +
C                              %trim(PDFPATH) + ",'         +
C                              '"pdfWindow","scrollbars,resizable,'

C                              'width=750,height=540");'+ $CrLf

C                              'pdfWindow;'             + $CrLf

C                              'pdfWindow.moveTo(3,3);' + $CrLf

C                              'history.back();'       + $CrLf     +
C                              '</script></html>'
C                   exsr      $APIStdOut

- PDFPATH is the webserver defined path to the IFS location and file
name.  example:

/webdirectory/pdfs/mypdffilename.pdf

the code will open a new window, and the pdf extension tells the
browser to open adobe reader and download the file.

after the new window is displayed, the original browser will return

using history.back() - to the page that requested the report.

hope this helps a little.
