RE: Processing... Please Wait... But with a subfile

["Shannon ODonnell" <sodonnell@xxxxxxxxxxxxxxx>]

The way I do that, and it works pretty well for me, is to create a display
file that has two record formats in it.  One is the message you want to
display (Processing...busy...whatever...) and which has the OVERLAY keyword
at the record level.

Let's call it S1

  A          R S1
  A                                      OVERLAY
  A                               B 2 60 'PROCESSING'


The second record format looks like this:

  A                                      DSPATR(HI) 
  A          R DUMMY                                
  A                                      KEEP       
  A                                      ASSUME     
  A                                      OVERLAY    
  A            DUMFLD         1A  O 13 79           
*************** End of data ************************



In your RPG program, wherever you want to display your "processing" message,
simply do this:   

 C                   Write    S1

Then do any other processing you want.   When your subfile is built, you can
then write it out like you normally do and continue on.  The S1 format will
disappear, (be overwritten) by the subfile control record and subfile record
formats.


BTW...you can find this tip and about 900 others just like it here: "The MC

Subject: Processing... Please Wait... But with a subfile

I just read the thread about informing the user that processing is
occurring.  My options include sndpgmmsg or issuing a Write (w/FrcDta
keyword on record format).   I want to go with the latter, and I'm
looking to do a little bit more.  I'd like to display a subfile as it's
being built w/o waiting for the user.  Essentially the user would see
the 'processing...' message above the subfile column headings, but would
also see any exception messages pop up at the same time.   At the end,
the window footer would display command keys appropriate to the result
of the processing.
 
My window is as such:
 
 * subfile
A R WdwSfl
 
 * subfile control (header)
A R WdwCtl    SflCtl( WdwSfl )
A                   Window(Wdw)
A                   FrcDta
A    96            SflDsp
A  N98            SflDspCtl
A    98            SflClr
A    96            SflEnd( *ScrBar )
 
 * window definition (footer)
A R Wdw
 
In the code:
// build record to write to subfile
SflClr = *Off               (in98)
WdwSflDsp = *On;     (in96)
WdwRRN += 1;
Write WdwSfl;
Write WdwCtl;    <------- error
Write Wdw;
 
If I remove the error statement, I only get a window (subfile is not
displayed).
 
Thanks,
