Check the file size before downloading

Hi there guys...

I'm having a problem at the moment... How can I check the file size before being transmitted to the server?

I was given a task to check if the file size limit is 500 KB and then block the download and warn the user.

According to my colleague from work... This is not possible with Javascript or Ajax... is there another method I can use?

kindly help... Thank you

It is a good answer, but it is interesting to note that Flash Player is itself a control ActiveX (when run in IE). In short, you need something beyond code that runs directly in the browser to do this. It can be done with just HTML and JavaScript in a web page.

  • With the help of cgi. CONTENT_LENGTH to check the file size before cffile

    I'll set up a form that allows users to upload files to our site ftp on the web server. I want to restrict the total size of the file to say 50 megs so I use an if statement and cgi. CONTENT_LENGTH to check the size of the file. It seems that the check can be done once the file is downloaded to a temporary file which defeats the purpose to check the size if it's already there. In my tests it make take 15 minutes to discover that my 52 meg file exceeded my limit of 50 MB. Is it possible to do the checking of file size before you actually download the entire file?

    Right, with cffile, you need to download everything first.

    There is a Flash/CFforms elegant solution that will allow you to access BEFORE upload file size. See ASFusion.com:

  • Create new report if the file size is too large

    The sequences I run in TestStand have the ability to generate large reports and I am looking for a way to start a new sequence of intermediate report if the file size exceeds certain limits, either start a new report every night at midnight.

    I am currently using TestStand 2014 and reports ATML 5.00.

    Here, any help would be greatly appreciated.

    I was hoping I'd be able to use some substitutions to get there, but it sounds a bit more complex than that. [...]

    There is no specific substitutions that solve this problem 'in configuration and only few implementation".

    The point is that you should follow the following steps:

    1. check the size of the file after writing a new segment of report data.

    2. If size > configured the file size, create a new file. Write a footer in the previous file, duplicate the header for the new file information and store the handle to file for all the previous files.

    3. once the test is complete, update the header in all files (remember: the header contains the overall result of the ESA.) This is known only when the test is finished!) and finalize all the report files.

    In the plugins default report, none of the above functions is applied.

    You want may also focus on 'File offline results' as a reporting mechanism. It might be easier to change things using this approach, unless you go the recommended manner: database.

  • The file size is huge despite the linked files

    Hi, I met a very strange thing.

    I am just placing some raster files in my illustration. I have always used the link option, because I keep my files in good condition and I really like the small files. (The contrary would be the Embed option, which saves the content placed in the file have.)

    But, despite a link to raster instead of embed files, my file have size gets really huge with the placed content. As a general rule, 80 MB with three raster images placed. It includes of course placed in any case files. And they are recorded in a sort of uncompressed format, too; the actual jpg file weigh only about 3 MB in total.

    Even more strange is the fact that if I move the content placed outside my work plan, the size of the file down again normal values (usually 600 kB). Means that the file size is something to do with the preview of the file or something, which (I think) is limited to the artboard.

    This has never been the case with Illsutrator before, has it?

    Is this really how Illustrator should behave, or I have some very odd here?

    InDesign handles content exactly how I like it: no incorporation of all.

    It is the ability to save a PDF compatible file that incorporates the images.

  • How to reduce the file size or reduce the document during the conversion to PDF.

    I have to download an onlind doc and can't download it if it is in PDF format.  I converted it all right, but they limit the saize equal to or less than 5 Meg file.  The file is a page, and it says it's Meg 6.3, so it won't, except the transfer of files.

    Hi speck300,

    If you want to reduce the file size of a PDF document, you must use Acrobat. If you do not have Acrobat, you're certainly welcome to try for http://www.adobe.com/products/acrobat.html. Acrobat Pro, there are several options to reduce the size of the file, including the file > save as other > PDF of reduced size and file > save as other > PDF optimized.
