  • Difference in select for update of ... in Oracle Database 10g and 11g

    - by sax
    Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience): DECLARE v_ename bonus.ename%TYPE; BEGIN SELECT b.ename INTO v_ename FROM bonus b JOIN emp e ON b.ename = e.ename JOIN dept d ON d.deptno = e.deptno WHERE b.ename = 'Scott' FOR UPDATE OF b.ename; END; / While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

  • Twitter @anywhere API problems in firefox only

    - by Brian Scott
    I've implemented a simple example of the Twitter @anywhere api to display user hovercards. The example works great in Internet Explorer and Chrome. However, whenever I the page loads in Firefox I receive the following message in an alert window: To set up @anywhere, please provide a client ID Surely if the results are correct in Chrome and IE then everything must be setup correctly? Here is a simple code block which I've tested recreates the problem in Firefox only: <script src="http://platform.twitter.com/anywhere.js?id=WMg5kRMlIw807lRTsktnNQ&amp;v=1" type="text/javascript" > </script> <script type="text/javascript"> twttr.anywhere(onAnywhereLoad); function onAnywhereLoad(twitter) { twitter().hovercards(); }); </script>

  • How can I manually interpolate string escapes in a Perl string?

    - by Ryan Thompson
    In perl suppose I have a string like 'hello\tworld\n', and what I want is: 'hello world ' That is, "hello", then a literal tab character, then "world", then a literal newline. Or equivalently, "hello\tworld\n" (note the double quotes). In other words, is there a function for taking a string with escape sequences and returning an equivalent string with all the escape sequences interpolated?

  • Can I customize the indentation of ternary operators in emacs' cperl-mode?

    - by Ryan Thompson
    In emacs cperl-mode, ternary operators are not treated specially. If you break them over multiple lines, cperl-mode simply indents each line the same way it indents any continued statement, like this: $result = ($foo == $bar) ? 'result1' : ($foo == $baz) ? 'result2' : ($foo == $qux) ? 'result3' : ($foo == $quux) ? 'result4' : fail_result; This is not very readable. Is there some way that I can convince cperl-mode indent like this? $result = ($foo == $bar) ? 'result1' : ($foo == $baz) ? 'result2' : ($foo == $qux) ? 'result3' : ($foo == $quux) ? 'result4' : fail_result; By the way, code example from this question.

  • Visual Studio 2008 profiler analysis - missing time

    - by Scott Vercuski
    I ran the Visual Studio 2008 profiler against my ASP.NET application and came up with the following result set. CURRENT FUNCTION TIME (msec) ---------------------------------------------------|-------------- Data.GetItem(params) | 10,158.12 ---------------------------------------------------|-------------- Functions that were called by Data.GetItem(params) TIME (msec) ---------------------------------------------------|-------------- Model.GetSubItem(params) | 0.83 Model.GetSubItem2(params) | 0.77 Model.GetSubItem3(params) | 0.76 etc. The issue I'm facing is that the sum of the Functions called by Data.GetItem(params) do not sum up to the 10,158.12 msec total. This would lead me to believe that the bulk of the time is actually spent executing the code within that method. My question is ... does Visual Studio provide a way to analyze the method itself so I can see which sections of code are taking the longest? if it does not are there any recommended tools to do this? or should I start writing my own timing scripts? Thank you

  • Help: My SSL Certificate expired but I can't renew it until Monday, is there any way I can disable SSL through IIS?

    - by Ryan
    Or perhaps force redirect to HTTP when they request HTTPS? I tried removing the SSL port settings under 'Advanced' but it broke the login page. I don't want to do a deploy/recompile right now but I am able to edit the VIEWS. However I am thinking there may be a way for IIS to do this, but then again I think the .NET code tries to force SSL. And yes, the key is that more support tickets will be caused by the browser giving a security error than if SSL was removed entirely for one day. Becaues they wouldn't very very likely not notice it being gone.

  • Displaying a notification when bluetooth is disconnected - Android

    - by Ryan T
    I am trying to create a program that will display a notification to the user if a Blue tooth device suddenly comes out of range from my Android device. I currently have the following code but no notification is displayed. I was wondering if it was possible I shouldn't use ACTION_ACL_DISCONNECTED because I believe the bluetooth stack would be expecting packets that state a disconnect is requested. My requirements state that the bluetooth device will disconnect without warning. Thank you for any assistance! BluetoothNotification.java: //This is where the notification is created. import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; public class BluetoothNotification extends Activity { public static final int NOTIFICATION_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); /** Define configuration for our notification */ int icon = R.drawable.logo; CharSequence tickerText = "This is a sample notification"; long when = System.currentTimeMillis(); Context context = getApplicationContext(); CharSequence contentTitle = "Sample notification"; CharSequence contentText = "This notification has been generated as a result of BT Disconnecting"; Intent notificationIntent = new Intent(this, BluetoothNotification.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); /** Initialize the Notification using the above configuration */ final Notification notification = new Notification(icon, tickerText, when); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); /** Retrieve reference from NotificationManager */ String ns = Context.NOTIFICATION_SERVICE; final NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); mNotificationManager.notify(NOTIFICATION_ID, notification); finish(); } } Snippet from OnCreate: //Located in Controls.java IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED); this.registerReceiver(mReceiver, filter1); Snippet from Controls.java: private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) { //Device has disconnected NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); } } };

  • Sharepoint publishing cache- counter missing on WFE(Object Caching)

    - by Ryan
    I want to tune object caching in my sharepoint environment. The way to do is check sharepoint publishing cache counter through perfmon on your farm. I have one application server and 2 WFE but when I am trying to create counter for my WFE its showing Sharepoint publishing cache but I am not able to add any instance of it but when I select my application server I can see all the instances. But If I want to check publishing hit ratio i need to run this on WFE also ...correct me if I m wrong? How to resolve this issue? Also, how to check the hit ratio as our site is not go-live so we don't get enuf users to hit the site to check this thing. Does it means that I can tune it up only my site go live and real load will get on it. Thanks, Amit

  • WPF - Two way binding use a user control...binding to object, not an element!

    - by Scott
    I created an object with a simple property with a default value. I then created a user control that has a text box in it. I set the datacontext of the user control to the object. The text box correctly shows the properties default value but I can't seem to update the property value when the user changes the text box value. I created a simple project to illustrate my code. Thanks for the help!! public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); } private string _titleValue; public string TitleValue { get { return _titleValue; } set { _titleValue = value; textBox1.Text = _titleValue; } } public static readonly DependencyProperty TitleValueProperty = DependencyProperty.Register( "TitleValue", typeof(string), typeof(UserControl1), new FrameworkPropertyMetadata(new PropertyChangedCallback(titleUpdated)) ); //Don't think I should need to do this!!! private static void titleUpdated(DependencyObject d, DependencyPropertyChangedEventArgs e) { ((UserControl1)d).TitleValue = (string)e.NewValue; } } <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBox Height="23" HorizontalAlignment="Left" Margin="94,97,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=TitleValue, Mode=TwoWay}"/> </Grid> </UserControl> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var dummy = new DummyObject("This is my title."); userControl11.DataContext = dummy; } private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show("The value is: " + ((DummyObject)userControl11.DataContext).Title); } } <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" xmlns:my="clr-namespace:WpfApplication1"> <Grid> <my:UserControl1 HorizontalAlignment="Left" Margin="95,44,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="191" Width="293" TitleValue="{Binding Path=Title, Mode=TwoWay}"/> <Button Content="Check Value" Height="23" HorizontalAlignment="Left" Margin="20,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </Grid> </Window>

  • Display the same prev/next usercontrol twice on a page

    - by Scott
    I haven't seen a question like this. I have a prev/next paging control on my page, one at the top and one at the bottom like this: top pager product catalog bottom pager Each pager is bound to a PagedDataSource that is exactly the same. I don't want to duplicate effort, so I am trying to figure out a way to do the processing once, but show the control twice.

  • Concatenating a string and byte array in to unmanaged memory.

    - by Scott Chamberlain
    This is a followup to my last question. I now have a byte[] of values for my bitmap image. Eventually I will be passing a string to the print spooler of the format String.Format("GW{0},{1},{2},{3},", X, Y, stride, _Bitmap.Height) + my binary data; I am using the SendBytesToPrinter command from here. Here is my code so far to send it to the printer public static bool SendStringPlusByteBlockToPrinter(string szPrinterName, string szString, byte[] bytes) { IntPtr pBytes; Int32 dwCount; // How many characters are in the string? dwCount = szString.Length; // Assume that the printer is expecting ANSI text, and then convert // the string to ANSI text. pBytes = Marshal.StringToCoTaskMemAnsi(szString); pBytes = Marshal.ReAllocCoTaskMem(pBytes, szString.Length + bytes.Length); Marshal.Copy(bytes,0, SOMTHING GOES HERE,bytes.Length); // this is the problem line // Send the converted ANSI string + the concatenated bytes to the printer. SendBytesToPrinter(szPrinterName, pBytes, dwCount); Marshal.FreeCoTaskMem(pBytes); return true; } My issue is I do not know how to make my data appended on to the end of the string. Any help would be greatly appreciated, and if I am doing this totally wrong I am fine in going a entirely different way (for example somehow getting the binary data concatenated on to the string before the move to unmanaged space. P.S. As a second question, will ReAllocCoTaskMem move the data that is sitting in it before the call to the new location?

  • Supress output from Visual Studio output pane (C++)

    - by Ryan Ginstrom
    When I run my Win32 project in the Visual Studio debugger, I get this huge screed of output about which DLLs were loaded, first-chance exceptions, and so on. Is there a way that I can suppress this output? Some day, I might want to know when 'C:\Windows\SysWOW64\ntdll.dll' was loaded, but normally I don't care. This is especially true when I'm running unit tests, and just want to be told whether any of the tests failed. This stuff isn't output with console applications, but it is with windows applications. To give an example of what I mean, here are the first lines from the output of a recent unit-test run. 'MyProject.exe': Loaded 'C:\dev\MyProject\Testing\MyProject.exe', Symbols loaded. 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\ntdll.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\kernel32.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\KernelBase.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\dbghelp.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\msvcrt.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\user32.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\gdi32.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\lpk.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\usp10.dll' 'MyProject.exe': Loaded 'C:\Windows\SysWOW64\advapi32.dll' ... and on and on ...

  • What are the pros/cons to these 2 ways of defining parameters for a web service method

    - by Antony Scott
    I have an existing web service I need to expand, but it has not gone into production yet. So, I am free to change the contracts as I see fit. But I am not sure of the best way to define the methods. I am leaning towards Method 2 for no other reason than I cannot think of good names to give the parameters classes! Are there any major disadvantages to using Method 2 over Method 1? Method 1 [DataContract(Namespace = Constants.ServiceNamespace)] public class MyParameters { [DataMember(Order = 1, IsRequired = true)] public int CompanyID { get; set; } [DataMember(Order = 2, IsRequired = true)] public string Filter { get; set; } } [ServiceContract(Namespace = Constants.ServiceNamespace)] public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(MyParameters params); } Method 2 public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(int companyID, string filter); }

  • Subclassing ViewPager Breaks Animation

    - by Ryan Thomas
    In my Android application I have an activity which uses a view pager to display 4+ pages (Fragments). I implemented buttons on each screen that move between pages by calling: pager.setCurrentItem(position, true); The view pager and fragments are all working as I desired. I then began looking for a solution to disable user swiping between pages so that the transition between pages in handled by the buttons only. The solution I found was mentioned in a few stackoverflow articles as well as This Blog that suggest subclassing the view pager to intercept touch events to disable swiping. I followed those examples by subclassing the view pager class as follows: public class ViewPager extends android.support.v4.view.ViewPager { private boolean enabled; public ViewPager(Context context, AttributeSet attrs) { super(context, attrs); this.enabled = true; } @Override public boolean onTouchEvent(MotionEvent event) { if (this.enabled) { return super.onTouchEvent(event); } return false; } @Override public boolean onInterceptTouchEvent(MotionEvent event) { if (this.enabled) { return super.onInterceptTouchEvent(event); } return false; } public void setSwipingEnabled(boolean enabled) { this.enabled = enabled; } } Using the subclassed view pager and calling setSwipingEnabled(false) works as was desired. The user can no longer move between pages with swipe gestures and I can still move between pages via button clicks by calling setCurrentItem(int position, boolean smoothScroll). However using the subclass breaks the animation between pages. When I call setCurrentItem(position, true) with android.support.v4.view.ViewPager I get very clean scrolling animations between pages. When I make the same call using the subclass the screen has a very brief 'flash' and then automatically draws the new page. I would like to know how to fix the animation while retaining the ability to disable user swiping between pages. I greatly appreciate any help with this. Let me know if you need any additional information. So far I have tested using a Samsung device running 2.3.5 and an AVD emulator targeting Android 2.3.3.

  • Validation of dependent properties in a "live edit" WPF app

    - by Ryan Cromwell
    I'm working on an app which supports live editing. That is you update properties in one area and their impact is seen in another with hitting "apply". Happens to be a charting app. One such edit "group" allows specifying a range. A triple range in fact: High, Target and Low. Our validation is such that High must be greater than target, target must be greater than Low (rocket science). Our dilemma is that the visual experience is a bit jarring when someone wants to go from say 30,20,10 to 15,10,5. I'm curious if anyone has implemented a mechanism for this scenario that might fit well in our situation such that we don't "yell" at the user as they change the range values.

  • How to handle customers with multiple addresses in CakePHP

    - by Ryan
    I'm putting together a system to track customer orders. Each order will have three addresses; a Main contact address, a billing address and a shipping address. I do not want to have columns in my orders table for the three addresses, I'd like to reference them from a separate table and have some way to enumerate the entry so I can determine if the addressing is main, shipping or billing. Does it make sense to create a column in the address table for AddressType and enumerate that or create another table - AddressTypes - that defines the address enumeration and link to that table? I have found other questions that touch on this topic and that is where I've taken my model. The problem I'm having is taking that into the cakePHP convention. I've been struggling to internalize the direction OneToMany relationships are formed - the way the documentation states feels backwards to me. Any help would be appreciated, Thanks!
