Tricking users/progress bar
I am calling a page that itself contains a CFHTTP call to an external resource that takes about 10-15 seconds to process. The problem is that nothing is displayed on the page until that processing is complete. What can I do to give a user some indication that something's going on instead of a blank page? Thanks! ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Tricking users/progress bar
Use CFFLUSH... Example: Please stand by while I do crap cfflush Be aware that there is a 'feature' of IE where it will only display HTML when the request is completely done, or it gets 'enough' HTML. So, that line I have in my example would NOT work if you didn't have enough HTML above it. If you find this happening, add a: #repeatString( ,200)# to your output. === Raymond Camden, ColdFusion Jedi Master for Mindseye, Inc Member of Team Macromedia Email: [EMAIL PROTECTED] Blog : www.camdenfamily.com/morpheus/blog Yahoo IM : morpheus My ally is the Force, and a powerful ally it is. - Yoda -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, March 07, 2003 9:28 AM To: CF-Talk Subject: Tricking users/progress bar I am calling a page that itself contains a CFHTTP call to an external resource that takes about 10-15 seconds to process.

ray have you made cfflush perform correctly on IE? I have not.

RE: Tricking users/progress bar
Did you see my note about 'tricking' IE? Sometimes you have to send extra text - that's why I use repeatString( ,200) before my cfflush. As for a working examples, go to the Example Apps and look for the CFFlush example. If you are using CF5, I believe the example was accidently hidden, but can be found in a folder called magicnumbers. === Raymond Camden, ColdFusion Jedi Master for Mindseye, Inc Member of Team Macromedia Email: [EMAIL PROTECTED] Blog : www.camdenfamily.com/morpheus/blog Yahoo IM : morpheus My ally is the Force, and a powerful ally it is. - Yoda -Original Message- From: Tony Weeg [mailto:[EMAIL PROTECTED] Sent: Friday, March 07, 2003 10:35 AM To: CF-Talk Subject: RE: Tricking users/progress bar ray have you made cfflush perform correctly on IE?

RE: Tricking users/progress bar
That's because your browser won't display a table until the /table tag has been flushed...

RE: Tricking users/progress bar
IE waits for the 1st 1000 or so characters before it starts to render. When we've needed it to work, we've put some really big comment at the top of the page (the best was a quote from Crime Punishment by my boss with the degree in Russian Lit).

RE: Tricking users/progress bar
Isn't there a trick with... the col tag - or some such - to make tables render part way? I _swear_ I remember reading something about a tag you can add to your tables so that they would be able to render as they were being built. === Raymond Camden, ColdFusion Jedi Master for Mindseye, Inc Member of Team Macromedia Email: [EMAIL PROTECTED] Blog : www.camdenfamily.com/morpheus/blog Yahoo IM : morpheus My ally is the Force, and a powerful ally it is. - Yoda -Original Message- From: charlie griefer [mailto:[EMAIL PROTECTED] Sent: Friday, March 07, 2003 11:03 AM To: CF-Talk Subject: Re: Tricking users/progress bar Tony Weeg writes: ray have you made cfflush perform correctly on IE?
