Michael As i say, i'm looking for a possibility. If it could work (not to slow) in CF, than that's the first solution. But indeed, we were also thinking of C# application.
If it does not disturb you, you may always mail me the notes and the pseudo-code, so i can analyse your way of thinking to handle this kind of problems. kind regards Tim -----Original Message----- From: Michael T. Tangorre [mailto:[EMAIL PROTECTED] Sent: dinsdag 19 augustus 2003 16:23 To: CF-Talk Subject: Re: Need to write Dispatcher! I'd look more towards a service running in the background. I was working on a C# app that does similar to what you are looking for. It "watched" a directory for two files: .dat file & .txt. When the directory had something placed in it, the routine would rename the files to the same name and move them to an outgoing mail folder for a email engine to pick up and send out. I initially tried this in CF and it was kind of slow. I can not say how much faster a service type app would be, but I'd venture to say it would be quite substantial. The above could get you going... a lot would go into a project such as you described in yoru post; this is just sratching the surface. If you would like, I can email you my notes and pseudo-code... like I say, I got sidetracked and never finished it., but maybe this weekend I can get back on it.

Additionally CFFILE also contains the ability to read the contents of a directory. The scheduler could be set to run the job every minute-- and if there is an error, you could always use CFMAIL for a quick notification. As an additional feature, you could log the sucesses of the job in the scheduled jobs log in CF administrator. > > >How to give uniqueID-filename? > How about a formated date created using the dateformat function. Here you can rename the image file (using CFFILE) with a unique file created by using the date. Others on the list may have other ideas for using other unique identifyers such as CFID/CFTOKEN or even server variables located in RAM. > > This dispatcher has to be also on a fail-over > >site and when the main side failes, the dispatcher on fail-over site > >needs to take over, and go on with the whole process (may be a manuel > >operation).
