• SQL - how to sort and filter a certain number of courses by using a setting

  Hello I am using Oracle 11 g 2 SQL in TOAD Version 11.5.1.1.2 editor
  
  I try to view all course numbers for my classroom that has the following conditions: only if the user specifies the code "adg" in parameter: programcode otherwise it will show all courses.
  
  ##A###
  ##C###
  ##N###
  ##Q###
  
  Where the third character of my number of course must be a (A, C, N, Q).
  
  However, I get the following error [error] performance (71:39): ORA-00907: lack the right parenthesis
  
  Select course_number

  Help will be greatly appreciated... Thank you!

  Hello

  That's what you asked for:

  SELECT  course_number
  FROM      classroom
  WHERE      NVL (:programcode, 'ok')     != 'adg'
  OR     SUBSTR (course_number, 3, 1)     IN ('A', 'C', 'N', 'Q')
  ;
  

  If you are intersested in what caused the error in the code you posted, it helps to format your code, while each "(" s'aligne sur sa droite de correspondance") left ', each CASE is aligned with its corresponding END and so forth:"

  Select  course_number
  from      classroom
  where      course_number = (
                         case
                             when  :programcode is null
                       then  course_number

  If you would care to post some sample data (CREATE TABLE and INSERT and something instructions for: programcode) then I could test it.

  The error was caused by the evil place ")" towards the end of the month. The outside CASE keyword was within 1 pair of parentheses, but its corresponding END was within 2 games.
  If you have solved that, you would get another error because of the inner CASE expression. Remember, each WHEN clause has to return a value in one of the types of SQL, such as NUMBER or VARCHAR2 data. What is the value in this data type SQL is returned by internally WHEN?

• How to disable the elements (gray out) in the DataGrid control?

  Hello

  I need to implement a component custom for a selectable list with a maximum selected items.

  in other words, when the selected items reached the maximum, all unselected items will be gray outside.

  Now I am able to use the DataGrid control to display a selectable (by itemRenderer) "checkbox" to the first column, to let the user select the item.

  And the name of the list in the second column.

  But I can't find a way to grey out (disable) these no selected item when max is reached.

  Can someone give advice?

  Here is my code snippet:

  SelectableListView.mxml

  < mx:VBox ' xmlns:mx = ' http://www.Adobe.com/2006/MXML " " width ="100%" height = "100%" "visible ="true">

  "" " < mx:DataGrid id ="list_datagrid"dataProvider =" {} {this.stringList}"showHeaders ="false"

  "" "" left = "5" rowCount ="16" rowHeight = "20" height ="83" width = "100%"top ="0"doubleClickEnabled = "true" doubleClick ="onDoubleClick (event)" >

  < mx:columns >

  " < mx:DataGridColumn id ="listCheckBox_col"dataField ="selected"editable ="false".

  "itemRenderer ="ListRenderer"width ="18"headerText =" ' resizable ="false" draggable = "false"/ > "

  " < mx:DataGridColumn id ="listName_col"dataField ="name" / >

  < / mx:columns >

  < / mx:DataGrid >

  < / mx:VBox >

  ListRenderer.mxml

  < mx:Canvas ' xmlns:mx = ' http://www.Adobe.com/2006/MXML " " width ="100%" height = "60" > "

  < mx:Script >

            <! [CDATA]

  private function setInUse(): void

                 {

  _data.selected = listInUse.selected;

                 }

  []] >

  < / mx:Script >

  "" " < mx:CheckBox id ="listInUse"width ="18"height ="18"click ="setInUse()"selected =" _data.selected{}"/ > "

  < / mx:Canvas >

  What is listInUse insdie the itemRenderer? I'm not very clear on how you use

  it. However, there are 2 ways to do this. Do not know if data.selected can be used

  to toggle the itemrenderer. I'll so guess not. Have a bindable extra

  "enabled" in your model of dataProvider property. Thus, when you reach the maximum of

  selected items through the collection and defined the set of the activated

  as a result. The enabled property of the renderer is linked to active so model

  It should be updated accordingly. The other way is to bind the license of the

  rendering engine on the selected. But as I said I don't know how your code works...

• How to populate a datagrid control?

  [Flex framework 3.0]

  How to fill a DataGrid using data to a sqlite database. In this case, what can be the dataProvider. I have to define bindable?

  Location:

  I have an AIR application that fills a SQLite database. The AIR App has a DataGrid. The content of the database must be in the datagrid control. There is a button that fills the database if you click. Accordingly the view IE the datagrid needs to update. Do I need to query the database using the SELECT command each time?

  My main question is to make the datagrid show the content of the database.

  Say the database has three columns.

  Help, please.

• How to loop through DataGrid (ArrayCollection, DataProvider collection)

  I need to loop through a collection ArrayCollection DataProvider or DataGrid (not sure which is best) so that I can insert information in a database through ColdFusion.

  The data grid has three columns: ID, item and quantity.  I have a table that contains these same fields.  The DataGrid control is pre-filled with a list of items.  The user can then enter the quantity of items in the DataGrid.  I then want to store this information in my table.  In ColdFusion, I would accomplish this through CFLOOP, however, in Flex I want to loop through the data grid so that I can get all the items and the quantities that the user has updated.

  I guess I have to do a loop in ActionScript, but I don't know how to do that.  Can anyone provide a suggestion and example code?

  Thanks again!

  How to do this.please help.

  No matter what welcome suggession

  Thanks in advance,

  Hello

  For that you call the same function on click of a button. This button is outside your datagrid control.

  public void deleteItem(event:MouseEvent):void {}
  dgArrayCollection.removeItemAt (dg.selectedIndex);
  dgArrayCollection.refresh ();
  }

  Thank you and best regards,

• DataGrid: can I recover the data, BUT it does not show the datagrid control

  Hello

  Hi - I've traced data through php mysql in actionscript but it does not show the datagrid control. Here is my code.

  Import fl.controls.DataGrid;

  Import fl.controls.dataGridClasses.DataGridColumn;

  Import fl.data.DataProvider;

  import flash.events.MouseEvent;

  import flash.net.URLLoader;

  to import flash.net.URLVariables;

  import flash.net.URLRequestMethod;

  import flash.net.URLLoaderDataFormat;

  Create a new instance of the DataGrid component.

  var aDg:DataGrid = new DataGrid();

  var myDp:Array = new Array();

  var myData:URLRequest = new URLRequest ("http://www.cambridgekids.es/kglad/php/getUsers.php");

  myData.method = URLRequestMethod.POST;

  var loader: URLLoader = new URLLoader();

  loader.dataFormat = pouvez;

  }

  aDg.dataProvider = new DataProvider (myDp);

  aDg.columns = ['number', 'Apellido'];

  aDg.setSize (800,300);

  aDg.move (150,200);

  aDg.rowHeight = 40; / / allows 2 lines of text in the default text size.

  aDg.columns [0] .width = 80;

  aDg.columns [1] .width = 30;

  aDg.resizableColumns = true;

  aDg.verticalScrollPolicy = ScrollPolicy.AUTO;

  addChild (aDg);

  DOH! I thought I was in the flex forum so ignore my previous answer.

  You must set the dataProvider on the dg after completing the dataprovider with data so spend aDg.dataProvider = new DataProvider (myDp); at the end of the dataOnLoad method

• Using a DataGrid control to get a RemoteObject

  What I have is a compound of two components. A component is a datagrid control that contains a list of users in it. The other component is just a group of checkboxes.
  
  Do I have to be able to do is select a user in the DataGrid and the second part, do trigger a RemoteObject call and returns the data about the person I selected in the datagrid control. What I need to know, is how to move selected users ID value to the RemoteObject call? The ID of the selected user is contained in an object called SelUserInfo.UserCnt. This object is sent to the second component when something is selected in the data grid. So far, that's what I have my code...
  
  My RemoteObject call:
  < mx:RemoteObject id = "getUserSec" destination = "ColdFusion" source = "ISIF. WebServices.Flex.UserData"ShowBusyCursor ="true">
  < mx:method name = "getUserSecRoles" result = "getRolesHandler (event)" >
  < mx:arguments >
  {SelUserInfo.UserCnt} < UserCnt > < / UserCnt >
  < / mx:arguments >
  < / mx:method >
  < / mx:RemoteObject >
  
  My Manager for the RemoteObject call:
  [Bindable]
  private var userSecRoles:ArrayCollection;
  
  private void getRolesHandler(event:ResultEvent):void
  {
  userSecRoles = new collection ArrayCollection (event.result as Array);
  }
  
  
  My function which is called when a user is selected in the datagrid control:
  public void getUserRoles(): Sub
  {
  getUserSec.getUserSecRoles.send ();
  }
  
  The problem is that the userSecRoles is always null. Does anyone know if I call the Number correctly?
  
  Have an ordinary day...
  KomputerMan ~ |  :-)

  Problem was found to be in the order that things were called. I would call the datagrid listener when a user has been selected by using this code:

  [Bindable]
  private var selectedUser2:Object;

  private void userSelHandler2(event:KDL_SelEvent):void
  {
  selectedUser2 = event. KDL_SelObject;
  getUserSec.getUserSecRoles (selectedUser2.UserCnt);
  Roles2TempID.getUserRoles (); initialize checkboxes
  }

  GetUserSec.getUserSecRoles (selectedUser2.UserCnt); line call my RemoteObject that calls the following event handler, to the Office of receiver data in a table.

  [Bindable]
  private var myUserSecRoles:ArrayCollection;

  private void getRolesHandler(event:ResultEvent):void
  {
  myUserSecRoles = new collection ArrayCollection (event.result as Array);
  }

  Problem is that the Roles2TempID.getUserRoles (); line of my datagrid selected event would trigger before the RO call was finished. In this way, I had all the data when the model is being developed. To resolve this problem, I call the code to initialize my model after that my manager RO be finished like this:

  [Bindable]
  private var myUserSecRoles:ArrayCollection;

  private void getRolesHandler(event:ResultEvent):void
  {
  myUserSecRoles = new collection ArrayCollection (event.result as Array);
  Roles2TempID.getUserRoles (); initialize checkboxes
  }

  Now the data is passed to the template until the model itself is initialized. My guess is that I have to do it this way because of Flex how threads. You mind just a guess. But it works now!

• How search/filter DataGrid

  Hello
  
  This is of course related to the Flex 2. I use an httpservice to fillup a datagrid. The question is, how do I filter data in the DataGrid based on an input string, as a search/filter feature.
  
  see you soon,

  Hello
  If your datagrid control then uses a collection of array as a dataprovider, you must use the arraycolletion.filterfunction to do it, if not, then try using a collection of table.

• How to fill a control ring with chains [] array?

  How to fill a control ring with chains [] array?

  It must be karma. (Try really bad karma because I couldn't post this question in my original)

  I must have been a Really bad guy in a previous life...  It's not like I'm bad in this one...

  So... what I want to do this time around?  Something that I thought would be easy... Well... it's a long story...  I had a simple solution, but the client wants something else.  -sigh-

  Here is what they want...  They want a control that allows for multiple selections to a control of the ring (or a control that allows a drop down selection menu).  Bites are filled at run time because it is based on 10 000 other precedents of things this particular choice.  So it must be dynamic.

  The snippet of code & images below show what I'm doing a little...

  The bottom image shows on the right bites which is filled in the control of the ring.  Since the number of items / items changes, I didn't have a bunch of controls stacked on another.  In addition, I have to deal with an unknown quantity of selections.

  Does anyone have a solution that can be recommended?  If so, can you share the solution / idea?

  Thank you

  I have posted a code that does something similar here: http://forums.ni.com/t5/LabVIEW/array-of-cluster/m-p/1822451#M625032

  It uses a table hint and individual controls that are moved on top of the table and populated as needed.  This approach might work for you?  You would need a two-column table and only control ring, which you would fill properly whenever the currently active cell changes.

• Sort by year, album, disc number

  I think the rocket and the clip kind something like (alphabetically) artist > album (alphabetically) > songs (according to track number). It would be better if this was sorted in this way: (alphabetically) artist > album (per year) > songs (with number of disk first, then track number) so if you have multiple disc albums, they are sorted properly. Or at least the possibility of being able to sort out this way. I played a bit with tags drive and the "rocket" numbers so the clip still doesn't sort them properly. If this has been corrected or added I think it will help a lot of people looking for a more refined way of sorting.

  ???

  I think he meant something like that

  Artist > title > disk. Track

  So if I understand it would be

  Kiss > Kissology > 1.12 (disc 1 track 12)

  This seems a bit messy. A cleaner way would be:

  Artist > Album > track 1 (Disc 1)

  Track 2 (Disc 1)

  Track 1 (Disc 2)

  Track 2 (Disc 2)

  .. (drive x) .with be invisible then it will look in the same way the "rocket" and clip already do. Just the sort is fixed.

  Edit: actually I just checked the fuse and the clip and that's exactly how they sort with the appropriate disk labels

  From what I remember, it's this track 1 from these two records would be just below or above eachother. If this problem occurs again I'll post on this lol.

• ESXI4.1 has how often is DRS control the CPU usage?

  ESXI4.1 has how often is DRS controls the use of the CPU on the host?

  I have 16 ESX host. Some of the hosts reach very hight CPU use, up to 98%, although some are as low as 52%. I understand DRS moves virtual machines only when you have to. I wonder how often it checks. Is there a set period of time, or DRS works in real time to check the hosts. Virtual machines are finally left guests busy, although guests were constantly busy today, about 90% + CPU, while some have been systematically 50%.

  On the 16 hosts, we have configured 1 host failover capability and the current capacity of 11 host failover. Affinity rules apply only to a limited number of virtual machines (about 6) of about 300.

  By default DRS is called every 300 seconds.

  It should work fine if you did changes properly. You will see directly the _dataid of the property which you type titleWindow. through code intellisense.

  As because you stated a public variable it must defenitely be accessible for the titleWindow instance. Please cross-check you do not have something wrong.

• Question about Drag and Drop using DataGrid controls

  I use two DataGrids, each has a different type of object so that you can imagine when you drag - move into the other it causes an error in the cause the objects are not the same.
  I already managed to do this work, on the dragDrop event, I stop the default behavior of the event by the preventDefault () method, this way I can convert manually one object in another and then add it to the target of DataGrid.
  The problem is that because I stopped the default behavior of the event that remains the target DataGrid highlighted all the time (focus is on that point), so I have to do after my manual conversion object is to restore the DataGrid control to its normal state, which is what would have made the event's default behavior.
  
  So any ideas how to do that? restore the DataGrid control in its normal state? or perhaps restore an event so that it can continue its default behavior?

  OK I have found, after calling the preventDefault method and make my own logic, you call the method of the DataGrid hideDropFeedback () and that will do the job
