We are creating a browser extension for IE. We are using the ATL and C++ to create the same.
we are writing a file: AuthTest.txt on successful login inside
%AppData%\Local\Microsoft\Internet Explore
to store some information during the session. On logout, we are deleting the file as well.
My question is when a user clears the cache of IE browser, AuthTest.txt will not be deleted.
So how would I delete the file on cache clear from my code?
IE maintains a database of the files that are in its cache. You have to tell IE about your file so it can be added to that database. Look at CreateUrlCacheEntry(), CommitUrlCacheEntryA(), and CommitUrlCacheEntryW(). Refer to MSDN for more details about working with the IE cache:

ok so i'm working on a new version of cflive.net and one of the features is to link to code.
I am using jsfiddle.net as my inspiration for the new site.
Now with jsfiddle all the code runs in the client, so it is not a problem for other people to edit it.
But with CFML obviously the files need to be saved on the server first, which means the original file would get overwritten if anyone makes any changes, which is obviously going to be problematic as the original author may not want his files to get edited, so I am looking for some feedback/suggestions on what would be the best way to handle this.
My best idea so far is.
All files are stored in a unique folder using a JsessionID
e.g. anonymous files
/jsessionid/filename.cfm
or user files
/user/jsessionid/filename.cfm
the original author marks the files as editable or not. You must register and be logged in to have this control.
Files created anonymously (not logged in) can be edited as default.
If the file is editable then it can be edited, otherwise it gets duplicated for each new session.
Anonymous sessions get deleted if they have not been access for 90 days.
thoughts?
I was charged with making some modification to an old application, and I created a new page which was being passed a URL parameter page_name, which is a you guessed it a name of a page with .cfm appended. So, in my haste, I continued using it, and was building out my CFC and using the page_name as the identifier for a record. Then I realized that there is a possibility of that name being duplicated in the table, and changed that url parameter to use the page_id, which is unique. I modified my CFC to use the new key, and nothing worked. So I started going through my code and figured I made a typo, started commenting things out, and finally dumped out my CFC object and voila, none of the edits I made were actually being used. This was fairly obvious, since page_name was a string, and page_id was numeric.
So I started googling,The first thing I saw as adjust things in the CFAdmin. I don't have access to it, and restarting the server isn't an option since I'm using an RDS to live code. The next thing I tried was to add applicationStop(), onApplicationStart(), to my Application.cfc. Well the problem is that the Application.cfc, is actually an Application.cfm. So after fiddling with the <cfapplication ... > tag, and nothing being updated, I'm here asking for help.
So is there a quick fix for this? Should I go ahead and create an application.cfc? I hope I explained myself, and sorry for all the text.
Confirm that your cfc is bound to either the session or application scope.
If it is, then you can rename the application in application.cfm and it will reset the object.
If your cfc is NOT bound to session or application scope, you have a cacheing issue. You need to go the the CF admin -> Server Settings -> Cache tab and uncheck component cache and possibly some others.

Sounds like you have been painted into a corner. Last option IF you have access the the server it self and can get into the C:\ or whatever drive that ColdFusion have been installed on, you can just manually delete the generated Java Class files that the server is using that has the old code. When ColdFusion sees there is no Class file it will recompile the newly changed file and whoa black betty go bam-a-lam your changes will be in production.

I'm having problems deleting entried from IE's downloads journal.
So I've found a file which responsible for storing this information. In my case file located here:
AppData%\Microsoft\Windows\IEDownloadHistory\index.dat
You can also obtain its location from registry - the key is HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Extensible Cache\iedownload and the variable is CachePath. If IE is running this file is locked. It is important for me to modify this file while IE is running because I'm trying to achieve that from a Browser Helper Object.
I also was trying to clean up this list using some of the WinInet methods: FindFirstUrlCacheEntry, FindNextUrlCacheEntry and DeleteUrlCacheEntry - but I'm not quite sure if those what I'm exactly looking for.
Since there are not so many information about this problem I was trying to use everything I've found relative...
Thanks in advance.
You can enumerate this entries using FindFirstUrlCacheEntryEx/FindNextUrlCacheEntryEx with parameters lpszUrlSearchPattern = L"iedownload:" and dwFilter = 0XFFFFFFFF.
I need to provide non-techie user ability to reliable download a few large files (3Gb) from URL without revealing the source URL of the file. Ideally I need single exe (without dependencies) that will download file from URL, specified inside exe: when user click on exe it just need show prompt where to save the file, and(optionally) will provide the user with some progress bar, for instance. The target URL can be specified directly in
the resource section, so I can edit URL path with HEX editor when I need set another path.
Wget are not suitable in my case, as its command line utility and requires user to specify an URL.
You could use the URLDownloadToFile function. Implement the IBindStatusCallback interface to receive progress information.
You really can't hide the source URL. Why are you trying to do that? If an end user runs tcpdump while they are running your program, they'll see where packets are coming from and going to.
I'd just provide them with a small batch file which calls ftp.exe. Tell your end user to drop the .BAT file where the downloaded file should go, and click it.
That solves quite a few problems, e.g. you know that your end user will be able to find the directory.
I have a collection of files which have been added to a verity collection. The filename, with complete path, has been used as the key.
I would like to move the location of the files on disk, but I am concerned that I will end up with duplicate entries (when I update the same file, the path to the file will be different, so I'll have an entry for the old file and an entry for the new one).
I wasn't involved with the original application setup, and I don't know much about verity or coldfusion (the rest of the app is in PHP). Can anyone suggest how I can go about running some sort of regex replace on each key in a verity collection, or possibly suggest another approach?
I would recommend to create new collection, adjust to your new specs (at least new path in your case) and swich to it in the application code (replace the collection name in cfindex/cfsearch).
After making sure it works properly you are free to delete the old one.
If you can not create collection for some reason, you can simply purge the collection, switch the path and re-index it.
Please note that you can do all of this directly from the application (maybe temporarily script) using cfcollection tag, and using CF Admin (see Verity Collections in menu) too.
