  • Cannot change the default program for opening .dll

    For some reason any, since I first linked the default program to open files .dll with Visual C++ 2010 Express (which is not truly attempt open, but instead of it gave me a message somewhere near the lines of "File not supported - Type does not open", incidentally) by chance I could not change since. I took a screenshot of the dialog box to try to change (URL below after all), but I noticed that the box was grayed out (the theme I have is a modified version of the classic Windows theme, but on 7, to clarify the operating system). I also tried to select a file after having hit the "Browse" button, but it didn't open anything. I tried several programs in the present to open, much less to change the default value (these are two notable examples): Netbeans - primarily an IDE for Java, but can open binary files even if she's not actually modify them (note: I changed absolutely nothing on any of them even if I has modified it to make it the default program but this problem affects more than just the ones) (, and it did not start until the last default) and Notepad. I went through the 'Open with' dialog box, and this is where I first encountered the problem of it (described above) outside the Control Panel, which it wouldn't let me change the association of file of it in particular, even if I didn't have one of these questions with any other type of file I tried to change, before or after this madness.

  • How to manually change the DNS zone files?

    I'm running OS X version 10.11.2 (El Capitan) and using App Server version 5.0.15 on a Mac Mini.

    I need to change the DNS Zone files manually because the DNS Server App Manager does not provide a U / I in order to add some elements (such as adding a delegation, etc.).  I use TextWrangler (5.0.2) as editor-in-Chief.

    I found an old post on how to do this here, but the information listed it seems obsolete.

    I was able to find the zone files to:

    / Library/server/name

    as:

    CBI .

    When I try to save or overwrite the db. files, or try to save all the files in that directory, I get an error indicating that:

    "Save the authenticated for this file failed (error application code: 20004).

    Since a window Terminal, if I go to that directory and type:

    Echo hello > temp.txt

    I get:

    Permission denied

    I am logged in using an administrator account.

    Before editing the db. files, I turned off the DNS in the App Server, then exit the server application server.

    What should I do to manually update the db. files?

    These files are protected from root.  You need to elevate your permissions to be able to change them.

    Probably you use a text editor like vi, nano or pico command line.  sudo vi/path/to/file for example.

    Back up the files first to protect against error.  In addition, be aware that Apple can run on some of your changes if you change the.app areas.

  • Can I globally change the names of files and or directory to lowercase to uppercase?

    in Windows XP or in Windows 7, globally change the names of files and or directory to lowercase to uppercase?

    A single configuration change probably will not accomplish this.

    Your best bet is probably the freeware "Bulk Rename Utility" program which has a section dedicated to change the case of file names.

  • Hi, is it possible to change the names of files that export out of indesign while packing?

    Hi, is it possible to change the names of files that export out of indesign while packing?

    For example, I can change the "Font of the Document" folder to export as a "document-fonts"?

    I ask because our naming structure requires without capital letters and no spaces. Spaces are replaced by dashes (-).

    And it would be nice if it was always exported as needed, instead of having to go back and change the names of files.

    Thank you! Much appreciated!

    Which cannot be changed without having a bad effect,. The name "Document fonts" is special. When you compress a file with fonts in a folder using exactly this name, InDesign know that these policies should be open and will be used in the document to the other end. If you name this file anything else, InDesign ignore fonts and the recipient will have to open the fonts manually.

    If you have decided to change the folder names, you will need to do once the package created, perhaps with a script.

  • How can I change the unrecognizable FrameMaker file format?  Why has he become unrecognizable after changing the file name?

    I update an existing project in the FrameMaker10, which is located in a structure of book.  I changed the names of the files in the directory, they upgrade 11 FrameMaker and saved.  When I try to add them to the book (whose name I also updated) a problem for some files. When I try t add them to the book file, I get an error message that says that the book file is unrecognizable.  (It allows me to add it, but it appears in the file book with an icon that has a blue "M" in there.)  Why is that happening and how can I change these files to normal FrameMaker files?  Thank you.

    Try to open the problem files using a text editor or viewer of files to see what the first bytes contain. Contains all the binary files valid FM FM 11 in the first bytes of the file.

    During the updating of the books, it is sometimes better just to create a new address book file and add files to it.

    When you rename files in a book, changes at the level of the system will break any links/cross-references between files, so it is always best to use the option rename book in the file to change the names of files FM. This will keep the correct links.
