HELP! opening a file allowed in the project

Hi,
I'd like to create and program a UI textfield in which the user writes the name of a .pdf file (there are different pdf files allowed in the project), so that the app decides which of this files opens.
The textfield will have to fill the: URLForResource:@"*****" withExtension:@"pdf"                                ***** is the name of the file
in the View Controller
How do I link the text introduced in a textfield to this field so that the user chooses manually the name of the file that is going to be open? Also, do I have to create another view to contain the textfield or can I use the same View controller?
Thanks,
Albert

How did you specify command line for your .hst file?
It should be something like "java -classpath
[youfile.jar] [youclass] %1"I have not specified command line for the .hst file.
The .hst file is just a file that is created when my main program (jar file) saves its files., later If I double click this saved hst file, it should be opened in the main jar program.
For the double click to work, I have created a constructor
public hst(String hstfile)
   //code to set the file contents in the window.
}the problem is that when I double click it says that the main jar file is not a valid win32 application, so what do I do ?
Cheers,
Raj

    Dear Sir/Madame,
    I am creating a exception report at the server-end using utl file utility. I want to display this report at the client end. A user doesn't have any access to server. Will u please write me the solution and oblige me.
    Thanks

    One way of doing this is to write a PL/SQL procedure that uses UTL_FILE to read the file and DBMS_OUTPUT to display the contents to the users.

    Good afternoon ladies and gentlemen!
    My question concerns the impossibility to open RAW-files directly from the program Adobe Bridge. At the moment when you open a RAW-file from Adobe Bridge by double-clicking, RAW-file is opened only in Photoshop. In the settings Adobe Bridge - in "open RAW-files by double-clicking in Adobe Camera Raw» box is checked. When you try any changes in the settings Adobe Bridge system displays a message:
    Bridge's parent application is not active. Bridge requires that a qualifying product has been launched at least once to enable this feature.
    The entire line of Adobe products on my computer updated to the latest updates. Previously, a family of products Adobe Photoshop on your computer is not set. Computer - PC, Windows 7 Enterprises.

  • How to hide the file name (the bizarre number assigned by the camera) when exporting an image version in aperture from an album. Pl understand I want to keep the file name in the project library version.

    how to hide the file name (the bizarre number assigned by the camera) when exporting an image version in aperture from an album. Pl understand I want to keep the file name in the project library version.

    Within Aperture you have Images, which are constructed on-the-fly from two files (the Master and the Version).  You get an image-format file _only_ when you export an Image.  You select the file name (usually a scheme) when you create an image-format file (that is, when you export).  Look under "Aperture→Presets→File Naming" for built-in Presets.  You can, of course, create your own or customize any provided.
    The Preset is applied to only the file newly created by your "export" command.  It is not applied to the Image in Aperture (unless you rename your Versions or your Masters).

  • Opening a file without hearing the previous one....

    How do we do to open a file without hearing the previous one if we open multiples files in a short time without willing to close the previous one each time ??

    If you don't wish to listen to all playing videos and it is too much trouble to stop or close non-foremost player windows, then don't use the QT X (or any similar) media player for playback. (I.e., this is what they are programmed to do.) Instead, use a media player like QT 7 which has a user preference that can be set so that only the "foremost" player window audio is heard when multiple videos are being played simultaneously.

    Not sure, but MacKeeper is trash and could be the source of it, among any other problems you may be having.  I suggest you uninstall it immediatley: http://applehelpwriter.com/2011/09/21/how-to-uninstall-mackeeper-malware/

  • This is actually a FF 4 RC question...but I can no longer open PDF files...the page just goes blank. No option in applications to set a PDF viewer as default. Help!

    How do you open PDF files in FF4 RC? The application section in options doesn't have PDF as an option to associate with a program. Whenever I click on a PDF file, I just get a blank tab.

    Hi there,
    You're running an old version of Safari. Before troubleshooting, try updating it to the latest version: 6.0. You can do this by clicking the Apple logo in the top left, then clicking Software update.
    You can also update to the latest version of OS X, 10.8 Mountain Lion, from the Mac App Store for $19.99, which will automatically install Safari 6 as well, but this isn't essential, only reccomended.
    Thanks, let me know if the update helps,

  • Where is the iak file defined in the project?

    I made changes to the *.iak file in MAX including the file name and now there are yellow bangs on the RT target and its subfolders in Project Explorer.  (The RT taget is a cFP-2110)  What is the best way to resolve this?
    Dave J.

    Dave,
    I lifted this out of the Fieldpoint help.  Suggest you make a backup of project before you try anything.
    Importing FieldPoint Configuration Files into LabVIEW Projects
    If you already have a FieldPoint system or systems configured in MAX, you can import your .iak configuration file to a new project in LabVIEW. Complete the following steps:
    Right-click the project name in the configuration tree and select Import»FieldPoint Configuration.
    Browse to the location of the .iak file, select it, and click Open.
    When you import a configuration file, LabVIEW makes a copy of the file for the project and automatically saves the file when you change the project. The original configuration file remains unchanged.

  • Help opening raw files in PSE 13

    Hello,
    I upgraded PSE 13 from PSE 9. I was using PSE 9 with my Nikon 600 (because I couldn't open the 600 raw files in PSE 9) by using the Adobe DNG converter. This was working fine. Since upgrading I can't open any Nikon 600 raw files in PSE 13 nor can I open the converted DNG files. It only recognizes jpeg files. The "Open in Camera Raw" option in the File drop down menu is also grayed out and can't be selected. I've tried the "updates" option from the Help menu and ran the updates, shut down PSE13 and also shut down computer and it still isn't working.  Wondering if I need to download a new ACR but can't find any that support the Nikon 600. Any help would be appreciated!

    Thank you for your help.
    When I do the "Help" drop down menu there isn't an option for "adobe plug-in" just "about plug-in" which doesn't list any options that seem to help when clicking on and none that say Camera raw.
    I read the manual instructions for downloading and am currently downloading the zip file; it is about 70% done. Will this help?
    This is what I'm referencing:
    These instructions were originally written to install ACR 8.2 for PSE11, but have been updated to install ACR 8.3 with PSE12.  While ACR 8.3 RC would work with PSE11, ACR 8.3 final will not.  Only PSE12 will host ACR 8.3.
    ACR 8.3 will work with PSE12 to open 70D files, but on an older Windows OS like Vista or XP  there is no compatible installer, so a manual install is the only option.  I should also say that the process outlined below does work on my Windows 7 64-bit computer, but I also have PS-CS6 and PS-CC installed on it, so it is possible that ACR 8.3 is dependent on something that wouldn't exist on a computer with only PSE installed on it, but someone else will have to confirm that.
    I was able to get 70D files to open in ACR 8.3 on PSE12 by doing the following:
    Download the ACR 8.3 for Windows update for PS-CC via the direct download link on the Adobe Blog - in the future this link will likely contain links to only newer versions of ACR but the process would be similar:
    http://blogs.adobe.com/crawlspace/2011/03/keeping-photoshop-up-to-date.html#notconnected
    Unzip this downloaded setup.zip to a folder somewhere.
    Inside the files from that zip is a folder called payloads \ AdobeCameraRaw8.0All-031213015928. 
    (Note that for future versions of PS and ACR the folder name will be different at the end, but the general format shold be similiar, and the important thing is that this is the folder without x64 in the path, because at this point PSE is a 32-bit program so we need the 32-bit version of the plug-in.  At some point in the future, PSExx may be 64-bit and the approporiate file or files could be the 64-bit version for the 64-bit version of PSE.  This zip file is for Photoshop which has both 32-bit and 64-bit versions so there are both versions of the plug-in as well.)
    Inside that folder is another ZIP called Assets1_1.zip so unzip it somewhere.
    Inside Assets1_1.zip there is a file called 1003.  This is the largest or perhaps only file in that zip and is the plug-in you need.
    Copy this 1003 file into the existing PSE12 camera raw plug-in folder:
    C:\Program Files (x86)\Common Files\Adobe\Plug-Ins\Elements 12\File Formats or for a 32-bit Windows OS, into:  C:\Program Files\Common Files\Adobe\Plug-Ins\Elements 12\File Formats
    Rename the existing Camera Raw.8bi to Camera Raw_8bi_80 (in case something doesn't work and you need to rename it back, later).
    Rename 1003 to Camera Raw.8bi
    After these steps you have the ACR 8.3 plug-in installed in PSE12 but not the camera and lens profiles, so install those by downloading and installing the DNG Converter 8.3:

  • Why do i need a newer version of number to open a file created on the present version?

    I have numbers 09 version2.3 (554).  It keeps telling me I need to buy an update to open a file i created weeks ago.  Why is this?  I have no updates pending.  Help?

    Check to see if you have a Numbers in your main Applications folder and another in a subfolder named iWork '09 within Applications. If so the Numbers in the main Applications folder is the latest version 3, while the version in the subfolder is Numbers 2.  Try opening the document with the version of Numbers you find in the main Applications folder.

  • How to open different files depending on the case

    Hi
    I have 3 cases within a case structure.
    When I select a first case, I need a certain VI to start.(I have done this by just dragging the VI within that case)
    But when I select the 2nd case, I need to an executable file to pop up, but I am not able to drag it within the case structure beacuse when I select something other than a than a vi, it gives me the follwing error.
    LabVIEW: File is not a resource file
    The file Test.exe cannot be loaded.
    Also, I need to open a text file, if I choose the 3rd case. I am not able to this also, as I end up getting the same error.
    Can someone help me to solve this problem?
    Thanks in advance
    Solved!
    Go to Solution.

    To call an executable you will have to use "System Exec.vi"
    To open text file you can use same "System Exec.vi" and give path of text file to open to "Command Line" input of the vi.
    Read help file so as to understand the function of "System Exec.vi"

  • How can I point the premiere to a blank folder and bring only the files needed for the project

    When I start premiere it loads all files from all my photo/video libraries (app 150 gb almost 20,000 photo).  I do not want to sort thru all these files for a project.  How can I point premiere Elements to a blank folder and get the appropriate media for a project as I
    need them.

    As Steve points out, there are really three programs in the Premiere and Photoshop Elements "suite," PrE, PSE and then Organizer, which links between the two, and is an Asset cataloging program. Because of the commonality of the GUI (Graphic User Interface), there can be confusion as to exactly which program one is in.
    If you launch just PrE, and not Organizer (can be launched from within either PrE, or PSE), the only Assets/media that you will see is that, which you have Imported into your Project.
    Also, having the Assets for a Project, in a separate folder, or folder structure, is a great way to set up the Project. This article goes into details on one set up method: http://forums.adobe.com/message/4491450#4491450
    Good luck, and hope that helps,

  • PSE 12: Mac need help opening RAW files

    I downloaded the trial version of PSE 12 on a Mac OS X v 10.8.5 and I am unable to open the CR2 RAW files taken by a Canon EOS Rebel XS and loaded directly to the Mac.
    The exact error message is, "Could not complete your request because the file appears to be from a camera model which is not supported by the installed version of Camera Raw. Please visit the Camera Raw help documentation for additional information."
    The Camera Raw plug in version on this PSE 12 is 8.2.0.94
    In an effort to open these CR2 files, I downloaded the DNG Converter 8_2. This provided a similar error, "The source folder does not contain any supported camera raw files."
    I believe that my camera is supported by PSE12 :
    I plugged an external hard drive into the Mac which contains CR2 files from the exact same camera. The files were unloaded using a Windows PC and then saved on the hard drive. They open on the Mac using PSE12. No problem.
    So, I am guessing that the problem is that I am a new Mac user. I have no idea where I should look on the Mac to figure out why the CR2 files directly loaded to the Mac won't open in PSE12 but files loaded to a WIndows computer and then opened on the Mac will open in PSE12.
    Any suggestions?

    Barbara B--thank you so much for trying to help me.
    I finally have success! I discovered that I must use the Canon EOS Utility to download the files to the Mac. Not iphoto and not the Image Capture.
    For anyone else who might need a link to the Canon Rebel XS EOS Utility, I found it here:
