  • How to quickly determine whether a file is an image file using iPhone/iPad SDK

    - by Josh Bleecher Snyder
    If I have a (potentially largish) file on disk, and I want to determine quickly whether UIImage will be able to load it. I don't necessarily trust the file extension to be reliable; I need to look at the actual data. I can (of course) load it into a UIImage, but that's relatively slow and rather memory intensive. I'd rather just peek at the first chunk of the file and make a decision. What's the fastest, most efficient way to go about this that is still fairly reliable? (Ideally, it'd be an Apple-provided API, but I didn't turn one up in my searches.) A 99.9% solution is good enough; I'm willing to have false positives in rare cases, such as when an image file has been truncated.

  • SSIS For Each File Loop and File System Task to copy Files

    - by Marlon
    I'm using a files system task inside a for each loop container, just as described here: link text However, when I execute the package I get this error: [File System Task] Error: An error occurred with the following error message: "The process cannot access the file 'C:\Book1.xlsx' because it is being used by another process.". I do not have the file open, and I assume no one else does, as I am able to copy, and open, and overwrite the file. Any suggestions would be appreciated. If you want an example package plz let me know.

  • Batch File - REN command's ErrorLevel returns 0 even on failure

    - by FMFF
    This is related to my earlier question. ren "C:\Temp\%%A" "C:\Temp\%%A" if errorlevel 0 ( "C:\Program Files\7-Zip\cmdline\7za.exe" a -tzip -mx9 "C:\temp\Zip\%%A.zip" "C:\temp\%%A" Move "C:\temp\%%A" "C:\Temp\Archive" ) In the above, the IF evaluates to true always, even if REN command fails. The idea is to check if a file is not locked by any other application, if not then Archive it and move it elsewhere. How best to do this? Thank you.

    - by user69514
    I have a file in which each line contains two numbers. The problem is that the two number are separated by a space, but the space can be any number of blank spaces. either one, two, or more. I want to read the line and store each of the numbers in a variable, but I'm not sure how to tokenize it. i.e 1 5 3 2 5 6 3 4 83 54 23 23 32 88 8 203

    - by Venno
    Hi, I am working on a project and I need to save user configuration. The configuration is a set of Jchechboxes I need to store their state (true, false). Which do you think is the better way of saving it, in a file and if yes in what (ini, cfg, txt), or it is better to serialize the object with the states?? Or if there is another way, please tell me :) Cheers

  • JFileChooser - multiple file filters?

    - by waitinforatrain
    Hi guys, I have a question about the JFileChooser in Swing. I'm trying to get multiple file extensions in the drop-down box, but have no idea how to do it. There is the method extFilter = FileNameExtensionFilter(description, extensions); that I can then use by writing fileChooser.setFileFilter(extFilter); however, as you can see, this only supports one option in the drop-down list. How do I add more?
