• I need to clean the registry because it has not been done in a long time.

  I need to clean the registry because it has not been done in a long time.  I can't find any software cleaner that cleans all teasers just identify errors and clean up maybe 3 things, but you need to buy to do it all.

  What can I do?

  Do not.  He didn't need it and even if you deleted 1000 things from him (doubtful) it would make little or no impact on performance.

  If you don't understand the registry enough to know what to erase manually or how to add things yourself, etc. - using a tool that almost arbitrarily find the things that are supposed to be orphaned or not necessary and confidence (for some reason any) can lead to a system of death.

  If you just * have to * ("it's a moral imperative") and then use that integrated with CCleaner.  I generally recommend not even consider using its registry "cleaning" component - but in the many times I used to analyze and find things and go through them manually before I remove them (at least - I've seen ~ 250 entries, he suggested to get rid of and even in this case, my manual check led me to delete all and there was no adverse) I didn't it go wrong.  If you * MUST * do it, use it and save your changes, so you might be able to roll back.  Before do you all - make sure your backups are in order.

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.

  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).

• EventLogger.logEvent returns false whenever

  I can't understand it.

  EventLogger.register returns true, but immediately after this call returns false:

  You must use:

  logEvent(long guid, long value, int level);
  

  Currently, you use logEvent (GUID, CODE):

  See the following link for possible levels:

• How to get a prompt to return a list of values based on a prompt

  Hello
  In the link below, I show the chain and the guest of the station.
  The guest of the station must return a list of value based on the value I have insert for string.
  If for example I have insert FS for the Four Seasons chain, what resort it must return only the hotels belonging to four seasons.
  I tried as in the example with a variable, but not worked.
  Any idea?
  
  http://img163.imageshack.us/img163/4486/resortprompt.jpg
  
  Thanks and greetings
  Giuliano

  Hello

  Do you have values for the stations for the value of the selected channel. I assume that you have no station for the selcted string value values. Try to select values of chain of 5 or 10 and then check the value of the station. To force them to work there is no need to define any variable presentation.

  Kind regards

• Record Collection Count = 1, but Exists is return false?

  Hi all
  
  OracleDB: 10g
  
  I have a record collection that I use to store information in a stored procedure. Before you do any work with it, I check if there is data in the file (. l_tab_cost_rec EXISTS (1)).
  
  What is strange, it's l_tab_cost_rec. Exists (1) returns false, but l_tab_cost_rec. Count returns a count = 1?
  
  Why East-Exists returns false, but the count is up to 1?
  
  Record definition:
  
  Type_cost_rec RECORD TYPE IS
  (item_id NUMBER
  item_cost NUMBER
  org_id NUMBER
  );
  
  TYPE tab_cost_rec IS TABLE OF type_cost_rec INDEX DIRECTORY.
  
  l_tab_cost_rec tab_cost_rec;

  How you assign the values in your table?

  It is quite possible to paste records into an associative array by index random, so your table may not have anything for the index of 1 (your_array (1)), but there might be something in the second index (your_array) (2). The number will always be 1.

  Note: I had to finegle the first half NVL function to the value expression for the result is 0 instead of-30. If you want it to be - 30 place just change this function nvl to nvl(t1.value,0) instead.

• return only the decimal value

  What function can I use to return only the decimal value of a formula

  (97 * 2.2) / 14 value returns 15.24

  I only want to use le.24

  Salvation is

  Use the formula - INT (formula)

  In the special case above:

  =(97*2.2)/14 - INT ((97*2.2)/14)

  You see two places to the right of the decimal separator in reason to be rounded off to the value real, in the shape of the cell to only show as two decimal places, either by setting the width of the cell close enough to force the rounding of the displayed value.

  Note that if the result is rounded (using the ROUND function) the actual value of the cell will be the rounded value. For the other two cases, the value displayed indicates only two decimal places, but the real value in the cell (and the additional calculations used by referring to this cell) is 0.242857142857144, which could lead to surprises in the results of the calculations downstream.

  Kind regards

• GetOpenFileNameW (using C++) API returning false

  Here is the snippet of code I use to open a file dialog box and select the file that is present in a folder whose name is consistes of double characters bye. I use Visual Studio 2005 and I did not "Character Set" property to "Unicode". (I won't do it for obvious reasons) Here is the code snippet.

  const int = 32767 nMaxFile;
  wchar_t * szFile = (LPWSTR) alloca (nMaxFile);

  OPENFILENAMEW ofn;
  HWN HWND;
  Memset (& OFN, 0, sizeof (OPENFILENAMEW));
  ofn.lStructSize = sizeof (OPENFILENAMEW);
  ofn.hwndOwner = *;
  ofn.hInstance = hInstance;
  ofn.lpstrFile = _TEXT (szFile) (LPWSTR);
  ofn.lpstrInitialDir = _TEXT (szDir) (LPCWSTR);
  ofn.lpstrDefExt = _TEXT ("ald") (LPCWSTR);
  ofn.nFilterIndex = 1;
  ofn.nMaxFile = nMaxFile;
  PNO. Flags = OFN_PATHMUSTEXIST | OFN_OVERWRITEPROMPT |
  OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_EXPLORER |
  OFN_ALLOWMULTISELECT | OFN_NOCHANGEDIR | OFN_HIDEREADONLY |
  OFN_SHAREAWARE;
  ofn.lpstrTitle = (LPCWSTR) ids (IDS_OPEN_DATABASE);
  CAPA::common:globalization:arrayauto_ptr pMultiString;
  JOINT (IDS_ALD_FILTER,(void*) & pMultiString);
  ofn.lpstrFilter = (LPCWSTR) pMultiString.get (); _TEXT ("text Files\0*.txt\0All fichiers\0 * \0\0"); // ;

  If (!.) GetOpenFileNameW(&ofn))
  return;

  It does not open the dialog box, and it is that getopenfilenamew returns false.
