• Pavilion Elite HPE-170 t: need help with the result of a command prompt to Power Options

  I have recently upgraded to Windows 10 in Windows 7.  Like so many thousands of people, I problelms of sleep mode.  Mine will not be auto-sleep.  It has been suggested that I saw to run command prompt: powercfg-applications

  It supposedly will list the items running on your computer which can now be auto-sleep to work.  I tried several times and up to now, I get the same item displayed each time.  This is what is displayed: \device\harddiskvolume2\windows\sysWOW64\svchost.exe (hpqddsvc) is followed by this message: a file delete operation is underway

  My first thought is that if there is an operation to remove file in progress all the time, it's maybe the reason why my computer is not auto-sleep.  If there is someone out there who can shed some light on this situation, I would appreciate the help.

  EUREKA * SOLVED
  

  I found the answer to my problem!  After using the control system: powercfg-query and get the answer: \device\harddiskvolume2\windows\sysWOW64\svchost.exe (hpqddsvc) delete file operation is in progress

  I started looking for whatever it is associated with the answer above.  In the Manager of tasks in respect of the services, I found the name of the file hpqddsvc, with a description of HP CUE DeviceDiscovery Service was running.  When I stopped the task and re-tried in opt power standby mode, it worked correctly.  In the Configuration of the system (by typing msconfig at the run prompt) on the Services tab, I unchecked the box for HP CUE DeviceDiscovery Service and rebooted the computer.  The service is no longer running.

  I'm sure that this Service has been added to my computer when I downloaded the hp.com/support product detection tool .  The tool scans your computer to detect and identify HP products.

  This can be useful to others who have the problem of the auto-sleep I've had.

• Help with the language setting

  I've fumbled while trying to set up my new Clip + and accidentally the language selected Arabic-now I can't change it to English because I can't read the poster! I tried to reset the player by pressing the power button, but when I turned it back on, he was always in Arabic mode.  I can do, or should I learn to read Arabic?  Thanks for any help!

  First, turn off the drive, then turn it back on.

  To access the language setting, press the Home button, which should return you to the main menu.  Highlight the settings icon, then press select.  Press the down button three times to access the system settings option.  It is the last option in this submenu.  Press select.

  Press the down button three times again, and it's the language setting.  Press select, and English is the first choice in this submenu.

• Help with the results of the analysis of the Consolidation

  My analysis of Virtual Center Consolidation ended on a server physical I analyze to put in VMware for these days.  I don't want a P2V it however, as it is a Windows 2000 SQL Server that I am about to rebuild from scratch as a Win2k3 x 64 + SQL 2005 x 64.  Then, without making the P2V process (I guess it will start when I proceed to 'Plan of Consolidation'), how can I find out what Virtual Center Consolidation is recommended for my new virtual machine?  I want to know if it recommends 2 vSMP processors and amount of memory.

  Thank you

  The generation of Consolidation software in vCenter is like a super scaled down version of VMware Capacity Planner, which is reserved for VMware partners.  This tool can give you more information on how to determine the capacity of the workload based on its current use.  You can use the performance monitor on the physical server to get an idea of the total use of the CPU, memory, disk, etc.  Unfortunately, you won't get these details with the generation Capacity Planner tool in vCenter.

  What are the specifications of the physical server?

• Need help with the sRGB setting works correctly.

  After reading a lot of comments from all kinds of sources, I decided for my purposes, it is best to put my Photoshop CS4 in sRGB. The problem I have is that often if I drag and drop an image as a new layer on another image I get a warning asking me if I don't know I "want to convert colors to a destination document with a color profile that does not match the current RGB workspace?"  She continues to tell me that my source is sRGB IEC61966 - 2.1 and that my destination is Adobe RGB (1998) and that the work is sRGB IEC61966 - 2.1.   Given that I put my Photoshop under Edit > settings of colors of sRGB IEC61966 - 2.1 and I have my camera to sRGB color I wonder why the window tells me that my destination is Adobe RGB (1998).  I initially shot in RAW and then open my photos in Camera Raw in Bridge and when I'm done with whatever changes, I want to do I simply 'Open Image' which, of course, it will open in CS4 where colors, is once again, sRGB.  What else do I need to change to get all operating under colour adjustment sRGB?

  Thanks for any help you can give.

  The color camera setting applies only to JPEG files as you shoot.

  If you shoot in RAW, then your image has a color space that is applied until you open it in Photoshop.

  At the bottom of your Camera Raw window is a hot blue link. Click it to open the workflow Options.

  Here, you can change the color space, Bit depth. Size and resolution that your image open in Photoshop.

  These settings in ACR to override settings you have for your default color space in Photoshop

  Thanks for posting the CREATE TABLE and INSERT.
  It is more useful if you post the code that can be run without modification. You did not semicolons after INSERTION instructions.

  Three questions:
  (1) I don't want to return results where table_name = "table1". I can't get this to work.

  What have you tried? Post your best attempt.
  Here's one way:

  SELECT    u.table_name
  ,        u.column_name
  ,        c.constraint_name
  FROM             user_tab_col_test      u
  LEFT OUTER JOIN  all_cons_columns_test  c
                          ON    u.table_name     = c.table_name
                 AND   u.column_name     = c.column_name
                 AND   c.constraint_name IN ('primary')
  WHERE       u.table_name     = 'table1'          --  *****  NEW  *****
  ORDER BY  u.table_name
  ,            u.column_name
  ;
  

  You would not put this condition in the clause; who controls what is considered as a match between the tables, and "u LEFT OUTER JOIN c" means show all lines of u, even if they do not have a match in the c.

  (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.

  Basically, this application is very well.
  It displays all the columns of user_tab_col_test; missing data_type. Just add u.data_type to the SELECT clause, or change the SELECT clause

  SELECT    u.*
  ,         c.constraint_name
  

  (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

  Do you mean "" * add * one-third * column * to all_cons_columns_test '? "
  It depends on what results you want. Post new CREATE TABLE and INSERT and instructions the results you want new data.
  Most likely, the basic structure of what you've written will remain exactly the same.

  Do not use the feature distribute the form. Instead of this, just put up a button "submit" and configure it to send email using any email address you want. Just add a button and set the action of the mouse upward on "Submit a form" and use a type mailto URL and specify that you want to send the full PDF.

• need help with the Update statement

  Hello
  I received a question in a course and I tried my best to respond, and now my brain is giving. I would really appreciate help with the update statement. I don't mind if you do not validate a solution, a little nudge in the right direction would be really useful. I'll post that I got.
  
  THE QUESTION
  / * For these agents disabled on more than seven missions, change their date of deactivation of the first date of deactivation of all the agents that have been activated in the same year as the agent that you update currently.
  */
  
  I have it divided into parts, here is my select statement to agents disabled on more than 7 missions, which produces the deactivation_dates in the agents table that I want to update...

  SELECT
  s.deactivation_date
  FROM
  (
  SELECT
  a.deactivation_date,
  count(m.mission_id) as nomissions
  FROM
  agents a
  INNER JOIN
  missions_agents m
  on
  a.agent_id=m.agent_id
  GROUP BY
  a.deactivation_date
  ) s
  WHERE
  s.nomissions>7 AND s.deactivation_date IS NOT NULL

  .. .and the code for the first date of deactivation for each year of activation agent

  select 
  a2.deactivation_date
  from
  agents a2
  where a2.deactivation_date= 
  (
  select min(a.deactivation_date)
  from 
  agents a
  where to_number(to_char(a.activation_date,'YYYY'))=to_number(to_char(a2.activation_date,'YYYY'))
  )

  ..... I am not real to marry these two statements together in the Update statement. I can't extract each date of deactivation produced in the first select statement and their match against the first date of deactivation in the year they have been activated for the second select statement.
  
  Any help greatly appreciated... :))

  I began to wonder how things would :)

  He recovers as soon as the subquery has not been correctly set in the SET clause. It seems you are trying to update a correlated, but we are still having a conceptual shift. I have added a few comments to your code above and below will explain.

  (1): when you do a correlated update it is useful to the table alias that you did right here.

  (2): this table statement is not necessary and is the reason why the FIRST deactivation date is selected. The alias that you use (3) refers to THIS table, not the one defined in the update statement. Remove the line indicated by (2) in the FROM clause and a correlated update will happen.

  and secondly why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)

  WHERE EXISTS
  (
  SELECT
  a.agent_id,
  count(m.mission_id)
  FROM
  agents a
  /* INNER JOIN AC ON AC.AGENT_ID = A.AGENT_ID */
  INNER JOIN
  missions_agents m
  ON
  a.agent_id=m.agent_id
  GROUP BY
  a.agent_id,
  a.deactivation_date
  HAVING
  count(m.mission_id)>7 AND a.deactivation_date IS NOT NULL
  )
  

  Once again this problem is similar to the question above that a correlation update doesn't work. Test existence of lines in an EXISTS subquery. Since your subquery is not related to the table that you are trying to update, it will be always return a line and, therefore, it returns true for EACH LINE in the AGENTS table. To limit the game to only agents > 7 missions results, you need to add a join condition that references the table in your update statement. I added one above (with comments) as a sample.

  I recommend you look over all material that you have associated with correlated subqueries, including documents that I posted above. This seems to be what you're having the problem more with. If you need me to explain the concept of correlated queries any better please let me know.

  Thank you!

• Hello need help with the opacity mask.

  Hello need help with the opacity mask. I hope someone out there can help

  I inherited a logo that appears to use a Logo of OM has a shape with a grad. This grad at first sight is not used in the Grad scheme and there is not editable.  Looking at the transparency palette I find an OM (pic1) output option. If I choose what the grad on separates it from the page of the form, that is from there I can change/remove as required (Note2).

  However, sometimes (he did no change), I'll be back to the same original form and output option is grayed out and is no longer available. Or I go to the similar shape that has the same treatment and I can't go out OM (pic3)

  The only difference is the thumbnail in the transparency palette, which is strong in pic1 and rated on pic3. What Miss me?    I'm not clear what the advantage is simply OM using the Grad palette to apply a grad in my form, but until I can get rid of OM who is there, I can't comfortably apply to the grad I want.

  The white gradient LHS I have no problem with. I choose fortunately only and each time get the possibility of release of OM.
  

  

  The other thing weird. When I select the white gradient. Sometimes, the exit option is in the palette without going through the drop-down list (Fig 4).

  Other times seems not that OM has already been applied, because the palette gives me the ability to mask rather than liberation (5 photos). Until I go to the drop down and then I find Release is an option after all.

  What is the difference here?   Not much of a problem, because either way I can release OM to be able to change the grad.

  The file is passed through several hands and play anywhere to try to resolve issues, and many stops and save slot, so something along the line was of course done a logo and not the other because of the difference, but I can't for the life of me see what that.

  

  I hope someone can help. Very appreciated

  
  

  See you soon

  Dave,

  I've (mis) understanding the issues, you can account for the box to the right in the main palette transparency (called thumbnail) here.

  Illustrator help | Transparency and blending modes

  represents the masking objects.

  Some of your screenshots show no object mask, so it only is not really a mask even if do the opacity mask has been clicked and there seems to be one in the layers palette, wherever you look.

  I think that it is perhaps the issue.

• Help with the session variable PHP CS5.5 - Please

  Hi all

  I am needing a little help with the help of a session variable, and I hope someone can point me in the right direction.

  I created a PHP page that uses the Dreamweaver 'User authentication' feature and the basics of this works very well, to direct a user to the correct page depending on whether they are or are not a valid user. I want to customize the page 'user valid' with people, user name entered in the authentication of the user table... a seemingly simple task using a session variable, but I just seem not to be able to make it work!

  The generated code for the AU on page 1 is the following:

  <? PHP

  Validate request to connect to this site.

  If (! isset {})

  session_start();

  }

  $loginFormAction = $_SERVER ['PHP_SELF'];

  If (isset($_GET['accesscheck'])) {}

  $_SESSION ['PrevUrl'] = $_GET ['accesscheck"];

  }

  If (isset($_POST['txtfirst_name'])) {}

  $loginUsername = $_POST ['txtfirst_name'];

  $password = $_POST ['txtsurname'];

  $MM_fldUserAuthorization = "";

  $MM_redirectLoginSuccess = "member_update.php";

  $MM_redirectLoginFailed = 'login.php ';

  $MM_redirecttoReferrer = false;

  @mysql_select_db ($database_panto, $panto);

  $LoginRS__query = sprintf ("SELECT firstname, name OF web_access WHERE firstname = %s AND family name = %s",

  GetSQLValueString ($loginUsername, "text"), GetSQLValueString ($password, "text"));

  $LoginRS = mysql_query ($LoginRS__query, $panto) or die (mysql_error ());

  $loginFoundUser = mysql_num_rows ($LoginRS);

  If {($loginFoundUser)

  $loginStrGroup = "";

  If (via PHP_VERSION > = 5.1) {session_regenerate_id (true) ;} else {session_regenerate_id() ;}

  Declare two session variables and assign them

  $_SESSION ['MM_Username'] = $loginUsername;

  $_SESSION ["MM_UserGroup"] = $loginStrGroup;

  If (isset($_SESSION['PrevUrl']) & & false) {}

  $MM_redirectLoginSuccess = $_SESSION ["PrevUrl"];

  }

  Header ("Location:".) $MM_redirectLoginSuccess);

  }

  else {}

  Header ("Location:".) $MM_redirectLoginFailed);

  }

  }

  ? >

  First of all, the text highlighted in red above seems to be setting the session variable that I need. Is this correct?

  If so, what is the code that I need to put on page 2 to use this session variable? or

  I have to do something else on the page 1 to correctly assign the session variable?

  Would be very grateful for your expertise

  Mark

  It seems that you put the columns incorrectly in the user authentication server behavior. This is the SQL query that checks the credentials of the user:

  $LoginRS__query = sprintf ("SELECT firstname, name OF web_access WHERE firstname = %s AND family name = %s",

  GetSQLValueString ($loginUsername, "text"), GetSQLValueString ($password, "text"));

  You are looking for first name and last name, while you should look for the user name and password of the user.

  $_SESSION ['MM_Username"] is a session variable that stores the login name of the user. To use it in a page, all that is needed is the page start with session_start(). You can then echo the value to display.

  If you want to display the person's true name, you must create a recordset in the second page, use of $_SESSION ['MM_Username'] to search for the first name and the patronymic. Alternatively, you can change the code like this (I copied only part of it):

  $LoginRS__query = sprintf ("SELECT firstname, surname OF web_access WHERE firstname = %s AND password is %s",

  GetSQLValueString ($loginUsername, "text"), GetSQLValueString ($password, "text"));

  $LoginRS = mysql_query ($LoginRS__query, $panto) or die (mysql_error ());

  $loginFoundUser = mysql_num_rows ($LoginRS);

  If {($loginFoundUser)

  $loginStrGroup = "";

  $row = mysql_fetch_assoc ($LoginRS);

  $_SESSION ['full_name'] = $row ["FirstName"]. ' ' . $row ['name'];

  If (via PHP_VERSION > = 5.1) {session_regenerate_id (true) ;} else {session_regenerate_id() ;}

  Declare two session variables and assign them

  $_SESSION ['MM_Username"] = $loginUsername;

  $_SESSION ["MM_UserGroup"] = $loginStrGroup;

  You can then use $_SESSION ['full_name'] in a page which begins with session_start().
