  I'm curious to know if all this code is necessary? Some of it seems to make things more difficult to work with... For example:
  
  1 - Why does the DW decide to take ['xVARx'] form variables and convert them to the $Vars? -Why not just use the GET ['xVARx']?
  
  2 - Why use sprintf in the $query_test: instead of something more direct as:
  
  SELECT * directory WHERE firstname LIKE $_GET ['firstname'] % and lastname LIKE $_GET ["lastname"] % - etc...
  
  Just curious why they chose these methods... Any idea would be appreciated...

  You cannot rely on the existence of $_GET ['xVARx']. You should always test
  with the isset() function if the URL parameter is set, before you can use it or load
  It's in a local variable. If it does not exist, you must initialize
  the variable with a default value. DW code does this, so that you can then
  use safely $xVARx - it contains the value of $_GET ['xVARx']
  or a usable default.

  Such a code is much harder to read and maintain, and more prone to error
  (Look at the quotes, for example). When you want to incorporate several
  variable in a string using sprintf() function is the most flexible way.

  You also missed a bit of detail. DW does not directly use the data
  the values in the string, but call first GetSQLValueString() on them.
  A correct management of the values submitted by users is very important to avoid
  Injection of SQL code. Your example above does not prevent this kind of attack.

  To add a little more to what Snakeyze said, you need not positioning at all.  Positioning CSS that is not specified or static default is all what it takes to 98% page layouts.

  To Center your page, you need 3 things:

  (1) a statement of type of valid document on the first line of your markup - DW performs this task for you when you create a new page,

  (2) with a width of container in pixels, ems or %.

  (3) a margin-left and margin to the right of "auto" (the default value of the browser).

  {body

  Width: 1000px; / * adjust to the REQ'd * /.

  margin: 0 auto; / * with width, this Centers page * /.

  Background: url (.. / images/Background.gif);

  }

  {#DropShadow}

  Background: url (.. / images/WhiteBackground.png) Center low no-repeat;

  min-height: 630px; / * height limit the height of the container, if necessary using min-height * /.

  Width: 800px;

  }

  {#Menu}

  margin: 0;

  padding: 0;

  Width: 270px;

  background-color: #FC0;

• Inserting a SWF... should I really all this code?

  Hello

  as you know, Dreamweaver adds tons of code when you insert a Flash object.

  I was wondering, being a phenomenon of optimization, how much it you actually need, especially if you take the Internet Explorer out of the picture.

  For example, how about this:

  <OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-555553540000" 
  WIDTH="550" HEIGHT="400" id="Example" ALIGN="">
      <PARAM NAME=movie VALUE="Example.swf"> 
      <PARAM NAME=quality VALUE=high> 
      <PARAM NAME=bgcolor VALUE=#FFFFFF>
  
      <EMBED src="Example.swf" quality=high 
      bgcolor=#FFFFFF  WIDTH="550" HEIGHT="400" 
      NAME="Example" ALIGN="" TYPE="application/x-shockwave-flash" 
      PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer">

• Why all this very slow loading on my computer lately?

  When I click on a program to open it, it is very slow to open an it.when I am online, sometimes it just freezes

  Hi dls4u2c,

  1. Did you the latest changes on the computer?
  2. You receive an error message on the computer?
  3. You have security software installed on the computer?
  4. When was the last time it was working fine?

  Method 1

  Check if the problem persists in the safe mode and after back with the results.

  http://support.Microsoft.com/kb/315222

  Method 2

  If the problem does not persist in safe mode, then it is possible that some third-party programs installed on the computer is causing the problem.

  I suggest that you put the computer in a clean boot state and check if it helps.

  To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  See section to learn more about how to clean boot.

  Everyone finds practically everything that they post here is being moderated? The big question for me is why? It used to be if you have included a couple of external links, it came down to one, even a YouTube video seems to trigger. If you mention a product that seems to trigger sometimes, but other times not. If moderation is done in a minute or two of fine, but I have something totally innocuous posted 10 minutes ago and it has not yet been approved.

• Why all the bad reviews of el capitan?

  Why all this negative opinions on El Capitan?

  In General, you should always pass to the last possible system like you meet the specs for, as long as you do not have "must have" applications that do not meet specifications. The idea that the updates/updates cause problems is probably derived from discussions that see you here. ASC is like an emergency room for people to have problems, especially the sick, those who come here. Hundreds of thousands of people pass without difficulty, never here and go merrily on their way. In addition to the improved features, updates/improvements important security fixes.

  Thank you

  public static final long MILLIS_IN_YEAR = 1000L * 60L * 60L * 24L * 365L
  

  Java language rules: an L after a literal integer in Java indicates that this constant should be kept as a long (64 bit signed) instead of int (32 bits signed).

  If you have not used to that, all the numbers on the line would be treated as integers (ints) (32 bit) and multiplier with an int int translates an int even if you want to store in a long.

  Since int cannot fully represent the full product (about 31.5 billion) as it is greater than Integer.MAX_VALUE (2 billion), so if you have not used the long as operands for multiplication, you finally get an incorrect value in MILLIS_IN_YEAR because the last multiplication would cause an overrun.

• This code cannot possibly. Why is it a failure?

  LV 2010 (Yes 2010), Win Vista.

  I have a SCREEN UPDATE event, occurring at 2 Hz.

  The event features an array of values, one for each channel.

  Four CHANNEL SELECTORS lead an INDEX TABLE operation.

  The four selected channels are shown separately on digital indicators and then combined with a waveform graph.

  The small subVIs are there to produce a NaN value to draw if the channel selector is - 1 (none).

  Currently, they are modified to generate a value for "123.0", for debugging purposes.

  AID indicates that the TABLE INDEX will produce a default value of 0 if the input index is outside the bounds of the array.

  

  However, in certain circumstances (see JING http://screencast.com/t/0kO0GDhlo0E), indicators of the "VALUE of the GRAPH' fail to update.

  In this video, I put the indicators to the values of 1, 2, 3, 4, before to start the program.

  I DO NOT set the DEFAULT value, simply enter the numbers in the lights on the Panel.

  The two selected channels are apparently normally updated.  The other two, who remain at ZERO (-1) do not update.

  I expect to see a zero, or SOMETHING, but the '3' and '4' never change.

  This code is called, as evidenced in the table of progress, but the values do not change.

  If I change the channel on a direct channel, then back to ZERO, it returns 0.  Which is expected.

  But why it isn't updated first?

  If I exchange the channel around selectors, the problem swaps with her. Any selector set to NONE has the corresponding indicator unchanged compared to the starting value.

  ON THE CODE:

  It is a CONCAVE VI, inserted in a secondary SCHOOL.

  Here is the embed code:

  

  The idea is that each control on the page is a secondary, each will receive an instance of a VI.

  For each school, I open a new ref becomes this VI (he put to be reentrant) and insert this ref in the secondary.

  I put a few values of control and launch it running.

  HIGHLIGHTS:

  1... If I change the OPTIONS = 8 options = 0 in the above, the problem goes away. Everything works as expected.

  2... N = 1 in the above, is simply to limit the number of instances, for debugging purposes.

  3... I get no error at any time.

  4... I tried with and without wire at the entrance to REFNUM REFERENCE OPEN VI VI TYPE SPECIFIER.  No change.

  A research on this topic raises some issues of 2008 with LV 8.0, and a suggestion there to serve the point inserted into a LIVING had no effect here.

  So, why not the seeing if the index is - 1, initially?  It's as if the code is not there.

  And why making it not reentrant fixed it?

  (I think I got this way so I can have multiple instances).

• All using windows movie maker, I added audio, but I can't hear the music while playing the video... Why is this?

  All using windows movie maker, I added audio, but I can't hear the music while playing the video... Why is this?

  Hello

  1. What is the format of the video file that you use in Movie Maker?

  2. do you receive error messages when you try to play the video?

  Some audio and video file formats are not supported in Windows Movie Maker and cannot be imported. However, if you have a video or audio file that is not taken care of, you can use a non-Microsoft video editing software to convert the file into a format supported by Windows Movie Maker, and then import the video file or an audio resulting in Windows Movie Maker.

  You can use your favorite search engine and download third-party video editing software to convert the file.

  Note: The use of third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  For more information, you can also consult the following articles:
