问题 I want to learn how to use the CFFILE tag from ColdFusion to read the contents of a text file. In my case, that text file is a progress log that is generated by FFMpeg while it transcodes a media file. I want to write a ColdFusion script that will poll the progress log periodically, until the log indicates that FFMpeg has finished its transcoding operation. On the client side I can then use Ajax to hit that ColdFusion script and show the user a "percentage completed" while FFMpeg does its

问题 For months, our IIS/ColdFusion server has been throwing 404 errors during Google crawler scans. Normally it's easy to track these down but in this case, Google is trying to scan our CFC files. The files do exist, but they are not exposed to the Internet - only to the ColdFusion server. Nevertheless, Google is seeing links to the CFCs somewhere on our site and is trying to follow them. Below is a dump of our CGI structure during one of the 404's. baseCFC is a CF Mapping to D:\Domains\[domain]

问题 What are the differences (if any) between New/CreateObject() to create an object vs EntityNew() to create an entity in CF9 for persistent CFC? 回答1: With New() and CreateObject() you need to specify the full path to the CFC. With EntityNew() you just need to pass in the name of the entity. 回答2: quoted from: Learning ColdFusion 9: EntityNew() vs. The NEW Operator / CreateObject() I actually asked this question during the "Advanced ORM" session at CFUNITED and got a slightly different answer.

问题 I have a persistent entity that I'm using as a template: Company Locations Departments Employees In other words, a Company contains many Locations , which contains many Departments , which contains many Employees . I have one Company set up as a template that should be copied when a new company is created. However, this template is persistent in the database. I tried using the following code to deep clone it: var template = EntityLoadByPK("Company", 13); var company = Duplicate(template);

问题 I'm using a Picasa RSS feed no problem but I can't get the original large size image that I uploaded. When uploading via Picasa I purposely chose to upload 'Original size' (quite big). The feed URL's only point to smaller images. How do I get the original big image from picasa? I'm able to hack to URL from inspecting the image on the Picasa website so this is an example of the photo I want: https://lh3.googleusercontent.com/-yam9QV2NG40/ULKIMTKvQzI/AAAAAAAAAA4/ownr930MvGg/ s2048 /Blasket

问题 Is there something built into Coldfusion that would let me know the browser and version number surfing my site? Are there existant libraries that would enable me to do this? My google-fu hasn't shown many things other than simple if statements detecting IE. I did do a dump of the cgi.http_user_agent variable in Chrome: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.77 Safari/534.24 There's three different browsers mentionned in there! Doing an if statement

问题 We upgraded our security scanner recently, and it's reporting a new issue. What's the recommended fix? (We happen to be on ACF9.) (Also, if you have an example exploit geared to CF, I'd appreciate it.) Unicode transformation issues Severity High Type Configuration Reported by module Scripting (XSS.script) Description This page is vulnerable to various Unicode transformation issues such as Best-Fit Mappings, Overlong byte sequences, Ill-formed sequences. Best-Fit Mappings occurs when a

问题 To get the current *.cfm file I use: GetFileFromPath(GetCurrentTemplatePath()) Is there a simple way to get the parent of the current file? I.e. if the current file is ...\MyApp\Users\addUser.cfm I want to return Users . Edit: the reason I want to do this is to check for access permission. Depending on path different policies will be enforced. Edit: The linked question doesn't provide the correct answer. 回答1: GetFileFromPath(GetFileInfo(GetCurrentTemplatePath()).parent) This will return

问题 I've been thrown into ColdFusion for a very simple assignment. The application has some logic to display "help codes" (let's not get into what is a help code), however, the logic is buggy and needs to be fixed. Given a two-letters code, a 1-4 digits number, and another 1-2 digits number, I would need to display them like this printf call would: printf("%s%04d%02d", letterCode, bigNumber, smallNumber); If you're not familiar with the printf function, it accepts a format string (the first
