Seek() in VIX, VDDK? How to search for a specific position

I am use to using seek() in Perl to access a part of the disk I want to read. Is there a seek() in the VIX, VDDK? It doesn't look like it, then, how would I do that?

Search (BLOB, 512, 0);           / * go to 512 bytes in position * /.

Read (BLOB, $type, 8);        / * read 8 bytes * /.

I think I might use VixDiskLib_Read to search and read, but I don't know if I have the right settings.

UInt8 buf [VIXDISKLIB_SECTOR_SIZE];             / * 512 * /.

VixError vixError = VixDiskLib_Read (disk. Handle(),

appGlobals.startSector, / * this is 0 * /.

1, buf);                                     / * I don't know what number I want here. I need 8 bytes to get the type of reading * /.

Thank you

Hello

IMHO, you have to read entire sectors, because it comes from the normally minimum data will deliver amount a disk API.

You want to read the first 8 bytes of the sector 1:

VixDiskLib_Read (disk. Handle(),

1, / / start with sector 1 (512 to 1023 bytes)

1, / / read a sector

Chamois); Buffer for 512 bytes

The first 8 bytes of the buffer contain the information you want to have...

Kind regards

  • How to search for a specific file on the computer?

    Original title: How can I search for a file by name only. For example, to prevent the display of other files that contain the same text.  This was easy to do under XP.

    For example, I need to find FILES named xyz*.mdl.  I need to filter all files that CONTAIN "xyz*.mdl" but are note NAMED "xyz*.mdl".

    This was easy in XP, but not in "7".

    Help, please.

    Thank you

    Doug

    You can use the syntax:

    filename:xyz * .mdl

    Note that file:xyz*.mdl is equivalent to filename:xyz * .mdl, but an additional symbol ~ is necessary with the equivalent of the so-called name: ~ xyz * .mdl to properly manage the wildcard character.  (file name, file and the name are supposed to be the same)

  • How to search for a Word document in Windows 8?

    I'm stumbling around Windows 8 that came pre-loaded on my new laptop.  I ordered Windows and Excel to be included in the package.  I saved a number of documents in Word, and now I need to get these documents for a particular.  I looked on the Internet and found a lot of no-help, that is to say, 'go in search of a file'.  Excuse me, but if I could find searching a file, I could probably find out how to search for the file, Huh?  Thus,.

    Could someone please help me with: how to find a Word document (1) and (2) where is the infamous "search"?

    I did the thing 'sweep to the right side of the screen"to get those things shadow to appear, and click on the magnifying glass (which I think the engineers forgot to change when they changed everything!) and if I wanted to search for apps, I'd be in great shape.  But his files I'm looking for, Word documents.  The designers of this 'new' version improved - well, new, in all cases seem to have forgotten those of use who use computers for productive work and not socialize or play games.

    Sorry for the hike and whining, but I'm very frustrated that the tasks that were once very simple are now extremely difficult to fill.

    It's pretty easy, at the beginning screen just type the name of your document and right it will bring the search screen and you select files (files, settings, Apps). Take a look at:

  • Please, give me an advise how to search for a number in a file xml (as3.0)

    Hello! Sorry for the troubling.

    Please, give me an advice how to search for a number in a file xml (as3.0)

    Thank you!

    My answer was based on your question to find numbers anywhere in the data to an xml file.  If you know that the data is digital data and the names of the nodes that contains this data, you do not have to check the characters and can only check numerical data using string values...

    function searchXMLFile(Event:MouseEvent):void
    {
    searchDisplay.text = "";
    var pageList:XMLList = xmlFileToSearch.receipt.number;
    searchDisplay.text = "false";
       
    for (var i: int = 0; i< pagelist.length();="">
    {

    If (pageList [i] == searchInput.text) {}
    searchDisplay.text = "true";
    }

    }
    }

    Even if you are looking for individual digital characters in the previous code that you would have always done by a false exit due having the line 'false' always cancel the real line...

    If (t.toString () .indexOf (m_sSearchTerm)! = - 1).

    {

    searchDisplay.text = "true";

    }

    searchDisplay.text = "false";  This will always overwrite the textfield

    How can I perform a search in windows 7, where he seeks in fact the content of the files?  Let's say I had a text called "mytext.txt" document and in this file was the text 'Hello World '...  How to make windows 7 return "mytext.txt" so if I did a search for the word 'Hello '?

    Hi angry bananas.

    The default function of Windows 7 search is such that it searches the text in the file name and content; in the file properties, such as in tags and. Therefore, in your scenario once you start to type Hello, you should get mytext.txt into the search results.

    Please see these articles using Windows for more information on the search for Windows 7.
