Subject: RE: CFFLUSH Advantages / Disadvantages
| Nick,
|
| I've found cf flush to be useful when you are serving up long tabular
| report data. If you are going to output several hundred rows,
| cfflush can help a lot. One approach I've used that works great for
| intranet sites where the browser is a known item is a combination of
| a status bar, _javascript_ and cfflush. I create a flash movie that
| has a status bar with frames from 1 to 100 (1 being an "empty" bar
| and 100 being "filled") based on a variable I can set using the
| "SetVariable( )" function in _javascript_. Then, as I'm outputting data
| I increment that variable using cfflush and _javascript_.
|
| For example, using MOD 100 (or whatever threshold makessense to you)
| and currrent row I could run a calculation that gives me the percent
| commplete of the output. let's say 13 percent at row 200. Then, I
| would write this: (<script>movie.SetVariable(13,"13%");</script>) ..
| the first item is the frame number I want the movie to go to and
| stop, the second variable is a label. I use <cfflush> to send it to
| the html page where it is run "inline" immediately. The result is a
| nice looking status bar that climbs incrementally at the top of the
| report and lets the user know that data is being sent to the browser
| and to please be patient. This approach can be useful for things like
| data upload tools where user uploads a spreadsheet or database that
| is subsequently inserted into a table or appended to a file. That's
| my 0.02.

| CF 4.5.1 and 5.0
|
| Any opinions on the use of CFFLUSH? From my understanding you have
| to deal with some tradeoff, e.g., it imposes several restrictions
| on the use of other tags and the method of client variable storage.
| The upside is not so clear, other than CFFLUSH help avoid time outs
| on slow Web sites?
|
| Thanks,
