  • Loop through multi-dimensional array and remove certain keys

    - by Webkungen
    Hi! I've got a nested tree structure which is based on the array below: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = Array ( [27] = Array ( [id] = 27 [parent] = 24 [name] = Add [uri] = 100 [basename] = news.public.add.php [child] = ) [28] = Array ( [id] = 28 [parent] = 24 [name] = Overview [uri] = 101 [basename] = news.public.overview.php [child] = ) ) ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = Array ( [29] = Array ( [id] = 29 [parent] = 25 [name] = Add [uri] = 67 [basename] = news.private.add.php [child] = ) [30] = Array ( [id] = 30 [parent] = 25 [name] = Overview [uri] = 68 [basename] = news.private.overview.php [child] = ) ) ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = Array ( [31] = Array ( [id] = 31 [parent] = 26 [name] = Add [uri] = 69 [basename] = news.event.add.php [child] = ) [32] = Array ( [id] = 32 [parent] = 26 [name] = Overview [uri] = 70 [basename] = news.event.overview.php [child] = ) ) ) ) ) ) I'm looking for a function to loop (recursive?) through the array and remove some keys. I my system I can allow users to certain functions/pages and if I deny access to the whole "block" "Events", the array will look like this: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = ) ) ) ) As you can see above, the whole "block" "Events" is useless right now, becuase there is no page associated with each option. So I need to find all "keys" where "basename" is null AND where child is not an array or where the array is empty and remove them. I found this function when searching the site: function searchAndDestroy(&$a, $key, $val){ foreach($a as $k = &$v){ if(is_array($v)){ $r = searchAndDestroy($v, $key, $val); if($r){ unset($a[$k]); } }elseif($key == $k && $val == $v){ return true; } } return false; } It can be used to remove a key any where in the array, but only based in one thing, for example remove all keys where "parent" equals "23". But I need to find and remove (unset) all keys where "basename" is null AND where child isn't an array or where the array is empty. Can anyone help me out and possibly tweak the function above? Thank you,

  • Why use NoSQL over Materialized Views?

    - by JustinT
    There has been a lot of talk recently about NoSQL. The #1 reason why I hear people use NoSQL is because they start to de-normalize their DBMS data so much so, to increase performance, that they end up with just one table with all of their data within that single table. With Materialized Views however, you can keep your data normalized, yet have it stored as a single table view for the same reasons why you'd use NoSQL. As such, why would someone use NoSQL over Materialized Views?

  • [iPhone] UIScrollView notifications

    - by ryyst
    Hi, I'm coding an app that works much like Apple's Weather.app: There's a UIPageControl at the bottom and a UIScrollView in the middle of the screen. In my code, I implemented the - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView method to figure out when the user did move to a new page. If they move to a new page, I load the adjacent pages' data, as to make further page-switching faster. (In one of Apple's examples, the - (void)scrollViewDidScroll:(UIScrollView *)sender is used, but that causes my app to shortly hang when loading a new page, so it's not suitable.) That code works very well. I'm using scrollRectToVisible:: to programmatically scroll inside the scrollview when the user clicks the UIPageControl. The problem is that the scrollRectToVisible: doesn't post a notification to the UIScrollViewDelegate when it's done scrolling - so the code responsible for loading adjacent pages never get's called when using the UIPageControl. Is there any way to make the UIScrollView notify its delegate when it gets called by the scrollRectToVisible: method? Or will I have to use threads in order to prevent my app from freezing? Thanks! -- Ry

  • Disable "mobile phone" and "fax" from joomla contact information

    - by Mala
    Hi I have a joomla installation with a contacts form. Specifically, there are two contacts with position, email, name, phone. However, joomla seems to insist on having two empty columns "Mobile phone" and "Fax" that I can't seem to get rid of. Neither contact has a mobile phone or fax, and they are disabled in both sets of contact parameters? what am I doing wrong? Thanks! Mala

  • Having trouble using psservice and sc.exe between Windows Server 2008 machines

    - by Teflon Mac
    I'm trying to control services on one W2k8 machine from another; no domain just a workgroup. The user account I'm logged in as is an administrator on both machines. I've tried both psservice and sc.exe. These work in a Windows Server 2003 environment but it looks like I need to an extra step or two due to the changed security model in 2008. Any ideas as to how grant permission to the Service Control Manager (psservice) or OpenService (sc)? I tried running the DOS window with "Run As Administrator" and it made no difference. With psservice I get the following D:\mydir>psservice \\REMOTESERVER -u "adminid" -p "adminpassword" start "Display Name of Service" PsService v2.22 - Service information and configuration utility Copyright (C) 2001-2008 Mark Russinovich Sysinternals - www.sysinternals.com Unable to access Service Control Manager on \\REMOTESERVER: Access is denied. In the remote server, I get the following message in the Security Log so I know I connect and login to the remote machine. I assume it then fails on a subsequent authorization step. The logoff message in the security log is just that ("An account was logged off."), so no extra info there. Special privileges assigned to new logon. Subject: Security ID: REMOTESERVER\adminid Account Name: adminid Account Domain: REMOTESERVER Logon ID: 0xxxxxxxx Privileges: SeSecurityPrivilege SeBackupPrivilege SeRestorePrivilege SeTakeOwnershipPrivilege SeDebugPrivilege SeSystemEnvironmentPrivilege SeLoadDriverPrivilege SeImpersonatePrivilege sc.exe is similar. The command syntax and error differs as below but I also see the same login message in the remote server's security log. D:\mydir>sc \\REMOTESERVER start "Registry Name of Service" [SC] StartService: OpenService FAILED 5: Access is denied.

  • How do I remove the on screen keyboard from the logon screen in Windows Remote Desktop Server 2008 R

    - by Gomibushi
    The on screen keyboard (OSK) from the "ease of access" tools pops up on EVERY connect to the server, even if you have not activated it. I can't seem to find a control panel or reg setting to switch it off. It is VERY "in your face" for linux users who connect at lower resolutions and do not provide all credentials, but have to type username and password. I'm running a 2008 R2 Terminal Server/Remote Desktop Server.

  • Select records from XML column (SQL Server 2005) based on node order

    - by jdoe
    I have a column in a SQL Server 2005 table defined as an XML column. Is there a way to select records from this table based on the order of two nodes in that column? For example, we have the following structure in our XML: <item> <latitude/> <longitude/> </item> I want to see if there are any records that have latitude/longitude in the opposite order i.e. <longitude/> then <latitude/>. I've tried some XPath expressions but with no luck.

  • java gui changing picture causes heapspace error

    - by pie154
    I have a java programme than when a button is clicked it updates the image on screen to the according image. this will work for the first 15 or so clicks then it causes a java heapspace error. I think it is because of the way I am updating the jpanel that contains the bufferedimage but not sure what the reason is. My code to get make the JPanel contain the new image is, public class extraScreenPanel { static JPanel screenPanel = new JPanel(new BorderLayout()); public static JPanel extraScreenPanel(int dispNum) { JLabel label = new JLabel("" + dispNum + ""); label.setPreferredSize(new Dimension(800, 600)); //label.setUI( new VerticalLabelUI(true) ); label.setVerticalAlignment( SwingConstants.TOP ); screenPanel = imgDisp(dispNum); label.setForeground(Color.white); label.setFont(new Font("Serif", Font.BOLD, 200)); screenPanel.add(label, BorderLayout.PAGE_END ); return screenPanel; } public static JPanel imgDisp(int picNum) { /* String url[] = new String[5000]; String part1; url[0] = "C:/PiPhotoPic/pic16.jpg"; for(Integer i=1;i<5000;i++){ if(i<10){part1 = "C:/temp/new0000000";} else if(i<100){part1 = "C:/temp/new000000";} else if(i<1000){part1 = "C:/temp/new00000";} else {part1 = "C:/temp/new00000";} String num = Integer.toString(i); url[i]= part1 + num + ".jpg"; } if(picNum<0){picNum=0;} String ref = url[picNum];*/ //this code is just to get specific ref for image location BufferedImage loadImg = loadImage(ref); JImagePanel panel = new JImagePanel(loadImg, 0, 0); panel.setPreferredSize(new Dimension(800, 600)); return panel; } public static class JImagePanel extends JPanel{ private BufferedImage image; int x, y; public JImagePanel(BufferedImage image, int x, int y) { super(); this.image = image; this.x = x; this.y = y; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(image, x, y, null); } } public static BufferedImage loadImage(String ref) { BufferedImage bimg = null; try { bimg = javax.imageio.ImageIO.read(new File(ref)); } catch (Exception e) { e.printStackTrace(); } BufferedImage bimg2 = resize(bimg,800,600); return bimg2; } public static BufferedImage resize(BufferedImage img, int newW, int newH) { int w = img.getWidth(); int h = img.getHeight(); BufferedImage dimg = dimg = new BufferedImage(newW, newH, img.getType()); Graphics2D g = dimg.createGraphics(); g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); g.drawImage(img, 0, 0, newW, newH, 0, 0, w, h, null); g.dispose(); return dimg; } } And the code that updates my gui is, it works by removing the panel from its containg panel and then readding it to it. picPanel = imgDisp.imgDisp(num); repaintPicPanel(); public static void repaintPicPanel() { picPanel.removeAll(); menuPanel.remove(picPanel);; menuPanel.add(picPanel, BorderLayout.LINE_START); }

  • C# keyhook question

    - by user203123
    I copied the following code from http://www.codeproject.com/KB/cs/CSLLKeyboardHook.aspx, public int hookProc(int code, int wParam, ref keyboardHookStruct lParam) { if (code >= 0) { Keys key = (Keys)lParam.vkCode; if (HookedKeys.Contains(key)) { KeyEventArgs kea = new KeyEventArgs(key); if((wParam == WM_KEYDOWN || wParam == WM_SYSKEYDOWN) && (KeyDown != null)) {KeyDown(this, kea) ;} else if ((wParam == WM_KEYUP || wParam == WM_SYSKEYUP) && (KeyUp != null)) {KeyUp(this, kea); } if (kea.Handled) {return 1;} } } lParam.vkCode ++; lParam.scanCode ++; return CallNextHookEx(hhook, code, wParam, ref lParam); } It works fine but when I make a little change: lParam.vkCode ++; or lParam.scanCode ++; right before the return CallNextHookEx(...), the original keys still appears in Notepad. Ex. If I press "a", I expect the letter in Notepad will be "b" but it still "a". It seems like "lParam" doesn't change. Couldn't understand why?

  • dismissModalViewControllerAnimated makes my app crash :(

    - by Koning Baard XIV
    I'm creating an iPad app, and I have two classes: NWRootViewController : UITableViewController and UINewFeedViewController : UIViewController. In NWRootViewController I have an UIBarButtonItem, which, when tapped, pops up a modal view controller called NWNewFeedViewController: // THIS CODE IS IN NWROOTVIEWCONTROLLER.M // New Feed -(IBAction)showNewFeedViewAction:(id)sender { [newFeedViewController setModalPresentationStyle:UIModalPresentationFormSheet]; [self presentModalViewController:newFeedViewController animated:YES]; } This works fine. However, in the NWNewFeedViewController's view, I have another UIBarButtonItem which does this when tapped: // THIS CODE IS IN NWNEWFEEDCONTROLLER.M // Buttons -(IBAction)cancelAction:(id)sender { [self dismissModalViewControllerAnimated:YES]; } When I tap this button, the app crashes with: 2010-04-10 12:39:46.703 News[580:207] *** -[NWDetailViewController cancelAction:]: unrecognized selector sent to instance 0x4741110 2010-04-10 12:39:46.705 News[580:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NWDetailViewController cancelAction:]: unrecognized selector sent to instance 0x4741110' 2010-04-10 12:39:46.705 News[580:207] Stack: ( 40878667, 2458187017, 41150267, 40613142, 40609810, 2776006, 4876265, 2776006, 3246293, 3255055, 3250242, 2899304, 2793965, 2825287, 49238396, 40419388, 40415304, 49232029, 49232226, 2817505 ) Can anyone help me?

  • How do I make an ellipse blink?

    - by MedicineMan
    I am trying to make a custom control in WPF. I want it to simulate the behavior of a LED that can blink. There are three states to the control: On, Off, and Blinking. I know how to set On and Off through the code behind, but this WPF animation stuff is just driving me nuts!!!! I cannot get anything to animate whatsoever. The plan is to have a property called state. When the user sets the value to blinking, I want the control to alternate between green and grey. I'm assuming I need a dependency property here, but have no idea. I had more xaml before but just erased it all. it doesn't seem to do anything. I'd love to do this in the most best practice way possible, but at this point, I'll take anything. I'm half way to writing a thread that changes the color manually at this point. <UserControl x:Class="WpfAnimation.LED" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <Ellipse x:Name="MyLight" Height="Auto" Width="Auto"/> </Grid> </UserControl>

  • Why is the 'this' keyword not a reference type in C++ [closed]

    - by Dave Tapley
    Possible Duplicates: Why ‘this’ is a pointer and not a reference? SAFE Pointer to a pointer (well reference to a reference) in C# The this keyword in C++ gets a pointer to the object I currently am. My question is why is the type of this a pointer type and not a reference type. Are there any conditions under which the this keyword would be NULL? My immediate thought would be in a static function, but Visual C++ at least is smart enough to spot this and report static member functions do not have 'this' pointers. Is this in the standard?
