  • IE 8 doesn't appear to clear cache on demand. Is anyone else seeing this?

    - by Steve
    I have a client that uploads updated pdf files to her Concrete5 CMS, through the file manager, replacing the old file with the same name. She then does a cms "clear cache" and exits as she should. Then, in testing, she finds that the old file still comes up when clicking on the link. On further review, the cms file manager version tracking shows that the file has been updated, and, for me, the new file comes up, as it should, when clicking the link. My client hase also refreshed her browser cache and still, she only gets the old file when clicking on the link. She says that, while she can't seem to force an immediate cache update, overnight it appears to update. My client is also part of a large company-wide lan and intranet. Is it possible that there is a cache function placed outside of her local browser and cms cache that is not updating?

  • Remove unncessary error raised by paperclip - filename is not recognized by the 'identify' command.

    - by kgpdeveloper
    I've been searching on how to solve this issue but could not find any real and working solution. User model: validates_attachment_content_type :avatar, :content_type = ['image/jpeg', 'image/pjpeg', 'image/x-png', 'image/png', 'image/gif'] Unnecessary error shows up when invalid file type is uploaded: Avatar /tmp/sample,23283,0.txt is not recognized by the 'identify' command. Server details: Ubuntu and Debian which identify results to /usr/bin/identify Specifying command path does not solve the issue: Paperclip.options[:command_path] = "/usr/bin" Any ideas? I looked at geometry.rb file and there seems to be something wrong with it. def self.from_file file file = file.path if file.respond_to? "path" geometry = begin Paperclip.run("identify", %Q[-format "%wx%h" "#{file}"[0]]) rescue PaperclipCommandLineError "" end parse(geometry) || raise(NotIdentifiedByImageMagickError.new("#{file} is not recognized by the 'identify' command.")) end Let me know if anyone has solved the same issue and how. Many thanks.

    - by fasil
    I need to find the size of an elf image for some computation. I have tried with the readelf utility on linux which gives the informations about the headers and section. I need to have the exact file size of the elf(on the whole). How do I find the size of the ELF from the header information or Is there any other means to find the size of an elf without reading the full image.

  • where from does paperclip get the name of original file?

    - by Pavel K.
    i started using nginx upload module (which creates upload files like /tmp/000121545) but i need paperclip to use original filename while saving files (like /public/avatars/LuckyLuke.jpg) previously in the parameters Rails were passing just "avatar"=>#<File:/tmp/RackMultipart20100413-6151-t3ecq0-0> no original filename as well, so i am wondering where from does it come in paperclip? i tried looking through plugin code but it's currently a bit too complex for me.

  • Regular Expression to replace a pattern at runtime(C#3.0)

    - by deepak.kumar.goyal
    I have a requirement. I have some files in a folder among which some file names looks like say **EUDataFiles20100503.txt, MigrateFiles20101006.txt.** Basically these are the files that I need to work upon. Now I have a config file where it is mentioned as the file pattern type as EUDataFilesYYYYMMDD, MigrateFilesYYYYMMDD. Basically the idea is that, the user can configure the file pattern and based on the pattern mentioned, I need to search for those files that are present in the folder. i.e. at runtime the YYYYMMDD will get replaced by the Year Month and Date Values. It does not matter what dates will be there(but not with time stamp ; only dates)). And the EUDataFiles or MigrateFiles names will be there.(they are fixed) i.e. If the folder has a file name as EUDataFile20100504.txt(i.e. Year 2010, Month 05, Day 04) , I should ignore this file as it is not EUDataFiles20100504.txt (kindly note that the name is plural - File(s) and not file for which the system will ignore the file). Similarly, if the Pattern given as EUDataFilesYYYYMMDD and if the file present is of type EUDataFilesYYYYDDMM then also the system should ignore. How can I solve this problem? Is it doable using regular expression(Replacing the pattern at runtime)? If so can anyone be good enough in helping me out? I am using C#3.0 and dotnet framework 3.5. Thanks

  • Associating a modifyable settings file with a class library in C# ?

    - by mishal153
    I have a class library(abc.dll) in which i have used a settings file. An exe (app.exe) references this class library. At runtime if i want to change the values of the settings without having to rebuild the class library/application, what is the best way to approach this problem ? In my current approach the setting values get embeded in the library, and thus i dont see any way to update them without rebuilding the whole thing.

  • How to upload a directory via Grails or Java ?

    - by fabien-barbier
    What is the best way to upload a directory in grails ? I try this code : def upload = { if(request.method == 'POST') { Iterator itr = request.getFileNames(); while(itr.hasNext()) { MultipartFile file = request.getFile(itr.next()); File destination = new File(file.getOriginalFilename()) if (!file.isEmpty()) { file.transferTo(destination) // success } else { // failure } } response.sendError(200,'Done'); } } Unfortunately, I can only upload file by file. I would like to define my directory, and upload all files directly. Any ideas ?
