• Setting up NCover for NUnit in FinalBuilder

  - by Lasse V. Karlsen

  I am attempting to set up NCover for usage in my FinalBuilder project, for a .NET 4.0 C# project, but my final coverage output file contains no coverage data. I am using: NCover 3.3.2 NUnit 2.5.4 FinalBuilder 6.3.0.2004 All tools are the latest official as of today. I've finally managed to coax FB into running my unit tests under NCover for the .NET 4.0 project, so I get Tests run: 184, ..., which is correct. However, the final Coverage.xml file output from NCover is almost empty, and looks like this: <?xml version="1.0" encoding="utf-8"?> <!-- saved from NCover 3.0 Export url='http://www.ncover.com/' --> <coverage profilerVersion="3.3.2.6211" driverVersion="3.3.2" exportversion="3" viewdisplayname="" startTime="2010-04-22T08:55:33.7471316Z" measureTime="2010-04-22T08:55:35.3462915Z" projectName="" buildid="27c78ffa-c636-4002-a901-3211a0850b99" coveragenodeid="0" failed="false" satisfactorybranchthreshold="95" satisfactorycoveragethreshold="95" satisfactorycyclomaticcomplexitythreshold="20" satisfactoryfunctionthreshold="80" satisfactoryunvisitedsequencepoints="10" uiviewtype="TreeView" viewguid="C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml" viewfilterstyle="None" viewreportstyle="SequencePointCoveragePercentage" viewsortstyle="Name"> <rebasedpaths /> <filters /> <documents> <doc id="0" excluded="false" url="None" cs="" csa="00000000-0000-0000-0000-000000000000" om="0" nid="0" /> </documents> </coverage> The output in FB log is: ... ***************** End Program Output ***************** Execution Time: 1,5992 s Coverage Xml: C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml NCover Success My configuration of the FB step for NCover: NCover what?: NUnit test coverage Command: C:\Program Files (x86)\NUnit 2.5.4\bin\net-2.0\nunit-console.exe Command arguments: LVK.IoC.Tests.dll /noshadow /framework:4.0.30319 /process=single /nothread Note: I've tried with and without the /process and /nothread options Working directory: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug List of assemblies to profile: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug\LVK.IoC.dll Note: I've tried just listing the name of the assembly, both with and without the extension. The documentation for the FB step doesn't help, as it only lists minor sentences for each property, and fails to give examples or troubleshooting hints. Since I want to pull the coverage results into NDepend to run build-time analysis, I want that file to contain the information I need. I am also using TestDriven, and if I right-click the solution file and select "Test with NCover", NCover-explorer opens up with coverage data, and if I ask it to show me the folder with coverage files, in there is an .xml file with the same structure as the one above, just with all the data that should be there, so the tools I have is certainly capable of producing it. Has anyone an idea of what I've configured wrong here?

• In Protobuf-net how can I pass an array of type object with objects of different types inside, knowi

  - by cloudraven

  I am trying to migrate existing code that uses XmlSerializer to protobuf-net due to the increased performance it offers, however I am having problems with this specific case. I have an object[] that includes parameters that are going to be sent to a remote host (sort of a custom mini rpc facility). I know the set of types from which these parameters can be, but I cannot tell in advance in which order they are going to be sent. I have three constraints. The first is that I am running in Compact Framework, so I need something that works there. Second, as I mentioned performance is a big concern (on the serializing side) so I would rather avoid using a lot of reflection there if possible. And the most important is that I care about the order in which this parameters were sent. Using XmlSerializer it was easy just adding XmlInclude, but for fields there is nothing equivalent as far as I know in Protobuf-net. So, is there a way to do this? Here is a simplified example. [Serializable] [XmlInclude(typeof(MyType1)), XmlInclude(typeof(MyType2)), XmlInclude(typeof(MyType3)) public class Message() { public object[] parameters; public Message(object[] parms) { parameters = parms; } } Message m = new Message(new object[] {MyType1(), 33, "test", new MyType3(), new MyType3()}); MemoryStream ms = new MemoryStream(); XmlSerializer xml = new XmlSerializer(typeof(Message)); xml.Serialize(ms,xml); That will just work with XmlSerializer, but if I try to convert it to protobuf-net I will get a "No default encoding for Object" message. The best I came up with is to use generics and [ProtoInclude] as seen in this example. Since I can have different object types within the array this doesn't quite make it. I added a generic List for each potential type and a property with [ProtoIgnore] with type object[] to add them and get them. I have to use reflection when adding them (to know in which array to put each item) which is not desirable and I still can't preserve the ordering as I just extract all the items on each list one by one and put them into a new object[] array on the property get. I wonder if there is a way to accomplish this?

• XML to be validated against multiple xsd schemas

  - by Michael Rusch

  I'm writing the xsd and the code to validate, so I have great control here. I would like to have an upload facility that adds stuff to my application based on an xml file. One part of the xml file should be validated against different schemas based on one of the values in the other part of it. Here's an example to illustrate: <foo> <name>Harold</name> <bar>Alpha</bar> <baz>Mercury</baz> <!-- ... more general info that applies to all foos ... --> <bar-config> <!-- the content here is specific to the bar named "Alpha" --> </bar-config> <baz-config> <!-- the content here is specific to the baz named "Mercury" --> </baz> </foo> In this case, there is some controlled vocabulary for the content of <bar>, and I can handle that part just fine. Then, based on the bar value, the appropriate xml schema should be used to validate the content of bar-config. Similarly for baz and baz-config. The code doing the parsing/validation is written in Java. Not sure how language-dependent the solution will be. Ideally, the solution would permit the xml author to declare the appropriate schema locations and what-not so that s/he could get the xml validated on the fly in a sufficiently smart editor. Also, the possible values for <bar> and <baz> are orthogonal, so I don't want to do this by extension for every possible bar/baz combo. What I mean is, if there are 24 possible bar values/schemas and 8 possible baz values/schemas, I want to be able to write 1 + 24 + 8 = 33 total schemas, instead of 1 * 24 * 8 = 192 total schemas. Also, I'd prefer to NOT break out the bar-config and baz-config into separate xml files if possible. I realize that might make all the problems much easier, as each xml file would have a single schema, but I'm trying to see if there is a good single-xml-file solution.

• Find out CRC or CHECKSUM of RS232 data

  - by Carlos Alloatti

  I need to communicate with a RS232 device, I have no specs or information available. I send a 16 byte command and get a 16 byte result back. The last byte looks like some kind of crc or checksum, I have tried using this http://miscel.dk/MiscEl/miscelCRCandChecksum.html with no luck. Anyone can reverse engineer the crc/checksum algorithm? here is some data captured with an RS-232 monitor program: 01 80 42 00 00 00 00 00 00 00 00 00 00 00 01 B3 01 80 42 00 00 00 00 00 00 00 00 00

• SQL Server to PostgreSQL - Migration and design concerns

  - by youwhut

  Currently migrating from SQL Server to PostgreSQL and attempting to improve a couple of key areas on the way: I have an Articles table: CREATE TABLE [dbo].[Articles]( [server_ref] [int] NOT NULL, [article_ref] [int] NOT NULL, [article_title] [varchar](400) NOT NULL, [category_ref] [int] NOT NULL, [size] [bigint] NOT NULL ) Data (comma delimited text files) is dumped on the import server by ~500 (out of ~1000) servers on a daily basis. Importing: Indexes are disabled on the Articles table. For each dumped text file Data is BULK copied to a temporary table. Temporary table is updated. Old data for the server is dropped from the Articles table. Temporary table data is copied to Articles table. Temporary table dropped. Once this process is complete for all servers the indexes are built and the new database is copied to a web server. I am reasonably happy with this process but there is always room for improvement as I strive for a real-time (haha!) system. Is what I am doing correct? The Articles table contains ~500 million records and is expected to grow. Searching across this table is okay but could be better. i.e. SELECT * FROM Articles WHERE server_ref=33 AND article_title LIKE '%criteria%' has been satisfactory but I want to improve the speed of searching. Obviously the "LIKE" is my problem here. Suggestions? SELECT * FROM Articles WHERE article_title LIKE '%criteria%' is horrendous. Partitioning is a feature of SQL Server Enterprise but $$$ which is one of the many exciting prospects of PostgreSQL. What performance hit will be incurred for the import process (drop data, insert data) and building indexes? Will the database grow by a huge amount? The database currently stands at 200 GB and will grow. Copying this across the network is not ideal but it works. I am putting thought into changing the hardware structure of the system. The thought process of having an import server and a web server is so that the import server can do the dirty work (WITHOUT indexes) while the web server (WITH indexes) can present reports. Maybe reducing the system down to one server would work to skip the copying across the network stage. This one server would have two versions of the database: one with the indexes for delivering reports and the other without for importing new data. The databases would swap daily. Thoughts? This is a fantastic system, and believe it or not there is some method to my madness by giving it a big shake up. UPDATE: I am not looking for help with relational databases, but hoping to bounce ideas around with data warehouse experts.

• Aquatic Prime on 10.6?

  - by Kevin

  Hello, I have 2 applications that I use with Aquatic Prime. One is an application just with the Aquatic Prime framework, and the other is an application that I've been working on that has been incorporated with the Aquatic Prime framework. The first application I mentioned before has its SDK set to 10.5 with the architecture to 32-bit. The second application I made has its SDK that is set to 10.6 (which it has to since I need NSRunningApplication) and its architecture to 32-bit. Now my question is, whenever I debug my first application it works perfectly fine, but with my second it gives me this interrupted error right after Running. What's going wrong? I've tried doing some breakpoints like "objc-exception-throw" but all it says is stopped at breakpoint 1. I need 10.6 in my application, but I also need Aquatic Prime. Can anyone help me solve this problem? Ok here's the one from the stack trace which I have no idea how to read: 0x91cdff11 <+0000> push %ebp 0x91cdff12 <+0001> mov %esp,%ebp 0x91cdff14 <+0003> sub $0x28,%esp 0x91cdff17 <+0006> mov %ebx,-0xc(%ebp) 0x91cdff1a <+0009> mov %esi,-0x8(%ebp) 0x91cdff1d <+0012> mov %edi,-0x4(%ebp) 0x91cdff20 <+0015> call 0x91cdff25 <objc_exception_throw+20> 0x91cdff25 <+0020> pop %ebx 0x91cdff26 <+0021> mov 0x8(%ebp),%esi 0x91cdff29 <+0024> lea 0xe4cbb8b(%ebx),%edi 0x91cdff2f <+0030> mov 0x4(%edi),%eax 0x91cdff32 <+0033> test %eax,%eax 0x91cdff34 <+0035> jne 0x91cdff3b <objc_exception_throw+42> 0x91cdff36 <+0037> call 0x91ce4f53 <set_default_handlers> 0x91cdff3b <+0042> mov %esi,(%esp) 0x91cdff3e <+0045> nop 0x91cdff3f <+0046> nopl 0x0(%eax) 0x91cdff43 <+0050> mov %esi,(%esp) 0x91cdff46 <+0053> call *0x4(%edi) 0x91cdff49 <+0056> lea 0xfd44(%ebx),%eax 0x91cdff4f <+0062> mov %eax,(%esp) 0x91cdff52 <+0065> call 0x91ce4e1f <_objc_fatal> The the GDB tells me its all good: run [Switching to process 990] Running… 2009-10-14 15:20:33.233 ApplicationName[990:a0f] init Sincerely, Kevin

• Need to set cursor position to the end of a contentEditable div, issue with selection and range obje

  - by DavidR

  I'm forgetting about cross-browser compatibility for the moment, I just want this to work. What I'm doing is trying to modify a script (and you probably don't need to know this) located at typegreek.com The basic script is found here. Basically what it does is when you type in characters, it converts the character your are typing into greek characters and prints it onto the screen. What I'm trying to do is to get it to work on contentEditable div's (It only works for Textareas) My issue is with this one function: The user types a key, it get's converted to a greek key, and goes to a function, it gets sorted through some if's, and where it ends up is where I can add div support. Here is what I have so far, myField is the div, myValue is the greek character. //Get selection object... var userSelection if (window.getSelection) {userSelection = window.getSelection();} else if (document.selection) {userSelection = document.selection.createRange();} //Now get the cursor position information... var startPos = userSelection.anchorOffset; var endPos = userSelection.focusOffset; var cursorPos = endPos; //Needed later when reinserting the cursor... var rangeObj = userSelection.getRangeAt(0) var container = rangeObj.startContainer //Now take the content from pos 0 -> cursor, add in myValue, then insert everything after myValue to the end of the line. myField.textContent = myField.textContent.substring(0, startPos) + myValue + myField.textContent.substring(endPos, myField.textContent.length); //Now the issue is, this updates the string, and returns the cursor to the beginning of the div. //so that at the next keypress, the character is inserted into the beginning of the div. //So we need to reinsert the cursor where it was. //Re-evaluate the cursor position, taking into account the added character. var cursorPos = endPos + myValue.length; //Set the caracter position. rangeObj.setStart(container,cursorPos) Now, this works only as long as I don't type more than the size of the original text. Say I had 30 characters in the div before hand. If I type more than that 30, it adds character 31, but places the cursor back at 30. I can type character 32 at pos.31, then character 33 at pos.32, but if I try to put character 34 in, it adds the character, and sets the cursor back at 32. The issue is that the function for adding the new character screws up if cursorPos is greater than what is defined in the range. Any ideas?

• json problems with making a ruby on rails application

  - by Prince Merdz

  So I'm using Bitnami to learn Ruby on Rails. I have also previously tried the manual installation for ruby and rails and was met by the same problem so I thought I should try first the easy package deal of Bitnami. Anyway my problem with json is that it causes the bundle install to fail. First the auto bundle install that rails new does fails because of an ssl error. Which is easily solved by changing the source in the gemfile which is https to http. However when I try to bundle install it does another error when it tries to install json.

• Can't override a global WPF style that is set by TargetType on a single specific control

  - by Matt H.

  I have a style applied to all my textboxes, defined in a resource dictionary.. <Style TargetType="TextBlock"> <Setter Property="TextBlock.FontSize" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontSize, Mode=OneWay}" /> <Setter Property="TextBlock.TextWrapping" Value="Wrap" /> <Setter Property="TextBlock.VerticalAlignment" Value="Center"/> <Setter Property="Background" Value="Transparent"/> <Setter Property="TextBox.FontFamily" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontName, Mode=OneWay}"/> </Style>\ The fontsize and fontstyle properties are bound to a special user settings class that implements iNotifyPropertyChanged, which allows changes to font size and fontfamily to immediately propogate throughout my application. However, in a UserControl I've created (Ironically, the screen that allows the user to customize their font settings), I want the font size and fontfamily to remain static. No matter what I try, my global font settings override what I set in my user control: <UserControl x:Class="ctlUserSettings" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:R2D2" Height="400" Width="600"> <Grid> <Grid.Resources> <Style x:Key="tbxStyle" TargetType="TextBox"> <Style.Setters> <Setter Property="FontSize" Value="14"/> <Setter Property="FontFamily" Value="Tahoma"/> </Style.Setters> </Style> ... etc... <StackPanel Margin="139,122.943,41,0" Orientation="Horizontal" Height="33" VerticalAlignment="Top"> <TextBox Style="{x:Null}" FontSize="13" FontFamily="Tahoma" HorizontalAlignment="Left" MaxWidth="500" MinWidth="350" Name="txtReaderPath" Height="Auto" VerticalAlignment="Top" /> <TextBox Style="{x:tbxStyle}" Margin="15,0,0,0" HorizontalAlignment="Left" Name="txtPath" Width="43" Height="23" VerticalAlignment="Top">(some text)</Button> </StackPanel> I've tried setting Style to {x:Null}, setting custom font sizes inline, and setting a style in the resources of this control. None take precedence over the styles in my resource dictionary. As you can see, I show a sprinkling of all the things I've tried in the XAML sample above... What am I missing?

I think my app crashes here: ListView DirectoryView = (ListView) findViewById(R.id.fileListView); So i think the error is in the activity_main.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:id="@+id/fileListView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > </ListView> Here is my LogCat: 09-09 11:19:21.254: E/Trace(1152): error opening trace file: No such file or directory (2) 09-09 11:19:21.484: D/AndroidRuntime(1152): Shutting down VM 09-09 11:19:21.484: W/dalvikvm(1152): threadid=1: thread exiting with uncaught exception (group=0x40a13300) 09-09 11:19:21.504: E/AndroidRuntime(1152): FATAL EXCEPTION: main 09-09 11:19:21.504: E/AndroidRuntime(1152): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.teamdroid.explorer/com.teamdroid.explorer.MainActivity}: java.lang.NullPointerException 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2059) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2084) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.ActivityThread.access$600(ActivityThread.java:130) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1195) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.os.Handler.dispatchMessage(Handler.java:99) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.os.Looper.loop(Looper.java:137) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.ActivityThread.main(ActivityThread.java:4745) 09-09 11:19:21.504: E/AndroidRuntime(1152): at java.lang.reflect.Method.invokeNative(Native Method) 09-09 11:19:21.504: E/AndroidRuntime(1152): at java.lang.reflect.Method.invoke(Method.java:511) 09-09 11:19:21.504: E/AndroidRuntime(1152): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 09-09 11:19:21.504: E/AndroidRuntime(1152): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 09-09 11:19:21.504: E/AndroidRuntime(1152): at dalvik.system.NativeStart.main(Native Method) 09-09 11:19:21.504: E/AndroidRuntime(1152): Caused by: java.lang.NullPointerException 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.Activity.findViewById(Activity.java:1825) 09-09 11:19:21.504: E/AndroidRuntime(1152): at com.teamdroid.explorer.listDirectory.getDirectory(listDirectory.java:20) 09-09 11:19:21.504: E/AndroidRuntime(1152): at com.teamdroid.explorer.MainActivity.onCreate(MainActivity.java:33) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.Activity.performCreate(Activity.java:5008) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1079) 09-09 11:19:21.504: E/AndroidRuntime(1152): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2023) 09-09 11:19:21.504: E/AndroidRuntime(1152): ... 11 more Please can you help me.

• custom view with layout

  - by user270811

  ok, what i am trying to do is to embed a custom view in the default layout main.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.lam.customview.CustomDisplayView android:id="@+id/custom_display_view1" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/prev" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="50" android:textAppearance="?android:attr/textAppearanceSmall" android:text="@string/prev" /> </LinearLayout> </LinearLayout> as you can see the class is called com.lam.customview.CustomDisplayView, with the id of custom_display_view1. now in the com.lam.customview.CustomDisplayView class, i want to use another layout called custom_display_view.xml because i don't want to programmatically create controls/widgets. custom_display_view.xml is just a button and an image, the content of which i want to change based on certain conditions: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/display_text_view1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <ImageView android:id="@+id/display_image_view1" android:layout_width="wrap_content" android:layout_height="wrap_content"> </ImageView> </LinearLayout> i tried to do: 1) public CustomDisplayView(Context context, AttributeSet attrs) { super(context, attrs); try { // register our interest in hearing about changes to our surface SurfaceHolder holder = getHolder(); holder.addCallback(this); View.inflate(context, R.layout.custom_display_view, null); ... but got this error, "03-08 20:33:15.711: ERROR/onCreate(10879): Binary XML file line #8: Error inflating class java.lang.reflect.Constructor ". 2) public CustomDisplayView(Context context, AttributeSet attrs) { super(context, attrs); try { // register our interest in hearing about changes to our surface SurfaceHolder holder = getHolder(); holder.addCallback(this); View.inflate(context, R.id.custom_display_view1, null); ... but got this error, "03-08 20:28:47.401: ERROR/CustomDisplayView(10806): Resource ID #0x7f050002 type #0x12 is not valid " also, if i do it this way, as someone has suggested, it's not clear to me how the custom_display_view.xml is associated with the custom view class. thanks.

• A python random function acts differently when assigned to a list or called directly...

  - by Dror Hilman

  I have a python function that randomize a dictionary representing a position specific scoring matrix. for example: mat = { 'A' : [ 0.53, 0.66, 0.67, 0.05, 0.01, 0.86, 0.03, 0.97, 0.33, 0.41, 0.26 ] 'C' : [ 0.14, 0.04, 0.13, 0.92, 0.99, 0.04, 0.94, 0.00, 0.07, 0.23, 0.35 ] 'T' : [ 0.25, 0.07, 0.01, 0.01, 0.00, 0.04, 0.00, 0.03, 0.06, 0.12, 0.14 ] 'G' : [ 0.08, 0.23, 0.20, 0.02, 0.00, 0.06, 0.04, 0.00, 0.54, 0.24, 0.25 ] } The scambling function: def scramble_matrix(matrix, iterations): mat_len = len(matrix["A"]) pos1 = pos2 = 0 for count in range(iterations): pos1,pos2 = random.sample(range(mat_len), 2) #suffle the matrix: for nuc in matrix.keys(): matrix[nuc][pos1],matrix[nuc][pos2] = matrix[nuc][pos2],matrix[nuc][pos1] return matrix def print_matrix(matrix): for nuc in matrix.keys(): print nuc+"[", for count in matrix[nuc]: print "%.2f"%count, print "]" now to the problem... When I try to scramble a matrix directly, It's works fine: print_matrix(mat) print "" print_matrix(scramble_matrix(mat,10)) gives: A[ 0.53 0.66 0.67 0.05 0.01 0.86 0.03 0.97 0.33 0.41 0.26 ] C[ 0.14 0.04 0.13 0.92 0.99 0.04 0.94 0.00 0.07 0.23 0.35 ] T[ 0.25 0.07 0.01 0.01 0.00 0.04 0.00 0.03 0.06 0.12 0.14 ] G[ 0.08 0.23 0.20 0.02 0.00 0.06 0.04 0.00 0.54 0.24 0.25 ] A[ 0.41 0.97 0.03 0.86 0.53 0.66 0.33.05 0.67 0.26 0.01 ] C[ 0.23 0.00 0.94 0.04 0.14 0.04 0.07 0.92 0.13 0.35 0.99 ] T[ 0.12 0.03 0.00 0.04 0.25 0.07 0.06 0.01 0.01 0.14 0.00 ] G[ 0.24 0.00 0.04 0.06 0.08 0.23 0.54 0.02 0.20 0.25 0.00 ] but when I try to assign this scrambling to a list , it does not work!!! ... print_matrix(mat) s=[] for x in range(3): s.append(scramble_matrix(mat,10)) for matrix in s: print "" print_matrix(matrix) result: A[ 0.53 0.66 0.67 0.05 0.01 0.86 0.03 0.97 0.33 0.41 0.26 ] C[ 0.14 0.04 0.13 0.92 0.99 0.04 0.94 0.00 0.07 0.23 0.35 ] T[ 0.25 0.07 0.01 0.01 0.00 0.04 0.00 0.03 0.06 0.12 0.14 ] G[ 0.08 0.23 0.20 0.02 0.00 0.06 0.04 0.00 0.54 0.24 0.25 ] A[ 0.01 0.66 0.97 0.67 0.03 0.05 0.33 0.53 0.26 0.41 0.86 ] C[ 0.99 0.04 0.00 0.13 0.94 0.92 0.07 0.14 0.35 0.23 0.04 ] T[ 0.00 0.07 0.03 0.01 0.00 0.01 0.06 0.25 0.14 0.12 0.04 ] G[ 0.00 0.23 0.00 0.20 0.04 0.02 0.54 0.08 0.25 0.24 0.06 ] A[ 0.01 0.66 0.97 0.67 0.03 0.05 0.33 0.53 0.26 0.41 0.86 ] C[ 0.99 0.04 0.00 0.13 0.94 0.92 0.07 0.14 0.35 0.23 0.04 ] T[ 0.00 0.07 0.03 0.01 0.00 0.01 0.06 0.25 0.14 0.12 0.04 ] G[ 0.00 0.23 0.00 0.20 0.04 0.02 0.54 0.08 0.25 0.24 0.06 ] A[ 0.01 0.66 0.97 0.67 0.03 0.05 0.33 0.53 0.26 0.41 0.86 ] C[ 0.99 0.04 0.00 0.13 0.94 0.92 0.07 0.14 0.35 0.23 0.04 ] T[ 0.00 0.07 0.03 0.01 0.00 0.01 0.06 0.25 0.14 0.12 0.04 ] G[ 0.00 0.23 0.00 0.20 0.04 0.02 0.54 0.08 0.25 0.24 0.06 ] What is the problem???

• Zend database query result converts column values to null

  - by David Zapata

  Hi again. I am using the next instructions to get some registers from my Database. Create the needed models (from the params module): $obj_paramtype_model = new Params_Model_DbTable_Paramtype(); $obj_param_model = new Params_Model_DbTable_Param(); Getting the available locales from the database // This returns a Zend_Db_Table_Row_Abstract class object $obj_paramtype = $obj_paramtype_model->getParamtypeByValue('available_locales'); // This is a query used to add conditions to the next sentence. This is executed from the Params_Model_DbTable_Param instance class, that depends from Params_Model_DbTable_Paramtype class (reference map and dependentTables arrays are fine in both classes) $obj_select = $this->select()->where('deleted_at IS NULL')->order('name'); // Execute the next query, applying the select restrictions. This returns a Zend_Db_Table_Rowset_Abstract class object. This means "Find Params by Paramtype" $obj_params_rowset = $obj_paramtype->findDependentRowset('Params_Model_DbTable_Param', 'Paramtype', $obj_paramtype); // Here the firebug log displays the queries.... Zend_Registry::get('log')->debug($obj_params_rowset); I have a profiler for all my DB executions from Zend. At this point the log and profiler objects (that includes Firebug writers), shows the executed SQL Queries, and the last line displays the resulting Zend_Db_Table_Rowset_Abstract class object. If I execute the SQL Queries in some MySQL Client, the results are as expected. But the Zend Firebug log writer displays as NULL the column values with latin characters (ñ). In other words, the external SQL client shows es_CO | Español de Colombia and en_US | English of United States but the Query results from Zend displays (and returns) es_CO | null and en_US | English of United States. I've deleted the ñ character from Español de Colombia and the query results are just fine in my Zend Log Firebug screen, and in the final Zend Form element. The MySQL database, tables and columns are in UTF-8 - utf8_unicode_ci collation. All my zend framework pages are in UTF-8 charset. I'm using XAMPP 1.7.1 (PHP 5.2.9, Apache at port 90 and MySQL 5.1.33-community) running on Windows 7 Ultimate; Zend Framework 1.10.1. I'm sorry if there is so much information, but I don't really know why could that happen, so I tryed to provide as much related information as I could to help to find some answer.

• How to create Query syntax for multiple DataTable for implementing IN operator of Sql Server

  - by Shantanu Gupta

  I have fetched 3-4 tables by executing my stored procedure. Now they resides on my dataset. I have to maintain this dataset for multiple forms and I am not doing any DML operation on this dataset. Now this dataset contains 4 tables out of which i have to fetch some records to display data. Data stored in tables are in form of one to many relationship. i.e. In case of transactions. N records per record. Then these N records are further mapped to M records of 3rd table. Table 1 MAP_ID GUEST_ID DEPARTMENT_ID PARENT_ID PREFERENCE_ID -------------------- -------------------- -------------------- -------------------- -------------------- 19 61 1 1 5 14 61 1 5 15 15 61 2 4 10 18 61 2 13 23 17 61 2 20 26 16 61 40 40 41 20 62 1 5 14 21 62 1 5 15 22 62 1 6 16 24 62 2 3 4 23 62 2 4 9 27 62 2 13 23 25 62 2 20 24 26 62 2 20 25 28 63 1 1 5 29 63 1 1 8 34 63 1 5 15 30 63 2 4 10 33 63 2 4 11 31 63 2 13 23 32 63 40 40 41 35 65 1 NULL 1 36 65 1 NULL 1 38 68 2 13 22 37 68 2 20 25 39 68 2 23 27 40 92 1 NULL 1 Table 2 Department_ID Department_Name Parent_Id Parent_Name -------------------- ----------------------- --------------- ---------------------------------------------------------------------------------- 1 Food 1, 5, 6 Food, North Indian, South Indian 2 Lodging 3, 4, 13, 20, 23 Room, Floor, Non Air Conditioned, With Balcony, Without Balcony 40 New 40 SubNew TABLE 3 Parent_Id Parent_Name Preference_ID Preference_Name -------------------- ----------------------------------------------- ----------------------- ------------------- NULL NULL NULL NULL 1 Food 5, 8 North Indian, Italian 3 Room 4 Floor 4 Floor 9, 10, 11 First, Second, Third 5 North Indian 14, 15 X, Y 6 South Indian 16 Dosa 13 Non Air Conditioned 22, 23 With Balcony, Without Balcony 20 With Balcony 24, 25, 26 Mountain View, Ocean View, Garden View 23 Without Balcony 27 Mountain View 40 New 41 SubNew I have these 3 tables that are related in some fashion like this. Table 1 will be the master for these 2 tables i.e. table 2 and table 3. I need to query on them as SELECT Department_Id, Department_Name, Parent_Name FROM Table2 WHERE Department_Id in ( SELECT Department_Id FROM Table1 WHERE guest_id=65 ) SELECT Parent_Id, Parent_Name, Preference_Name FROM Table3 WHERE PARENT_ID in ( SELECT parent_id FROM Table1 WHERE guest_id=65 ) Now I need to use these queries on DataTables. So I am using Query Syntax for this and reached up to this point. var dept_list= from dept in DtMapGuestDepartment.AsEnumerable() where dept.Field<long>("PK_GUEST_ID")==long.Parse(63) select dept; This should give me the list of all departments that has guest id =63 Now I want to select all departments_name and parent_name from Table 2 where guest_id=63 i.e. departments that i fetched above. This same case will be followed for Table3. Please suggest how to do this. Thanks for keeping up patience for reading my question.

• How to split HTML code with javascript or JQuery

  Hi I'm making a website using JSP and servlets and I have to now break up a list of radio buttons to insert a textarea and a button. I have got the button and textarea to hide and show when you click on the radio button it shows the text area and button. But this only appears at the top and when there are hundreds on the page this will become awkward so i need a way for it to appear underneath. Here is what my HTML looks like when complied: <form action="addSpotlight" method="POST"> <table> <tr><td><input type="radio" value="29" name="publicationIDs" ></td><td>A System For Dynamic Server Allocation in Application Server Clusters, IEEE International Symposium on Parallel and Distributed Processsing with Applications, 2008</td> </tr> <tr><td><input type="radio" value="30" name="publicationIDs" ></td><td>Analysing BitTorrent's Seeding Strategies, 7th IEEE/IFIP International Conference on Embedded and Ubiquitous Computing (EUC-09), 2009</td> </tr> <tr><td><input type="radio" value="31" name="publicationIDs" ></td><td>The Effect of Server Reallocation Time in Dynamic Resource Allocation, UK Performance Engineering Workshop 2009, 2009</td> </tr> <tr><td><input type="radio" value="32" name="publicationIDs" ></td><td>idk, hello, 1992</td> </tr> <tr><td><input type="radio" value="33" name="publicationIDs" ></td><td>sad, safg, 1992</td> </tr> <div class="abstractWriteup"><textarea name="abstract"></textarea> <input type="submit" value="Add Spotlight"></div> </table> </form> Now here is what my JSP looks like: <form action="addSpotlight" method="POST"> <table> <%int i = 0; while(i<ids.size()){%> <tr><td><input type="radio" value="<%=ids.get(i)%>" name="publicationIDs" ></td><td><%=info.get(i)%></td> </tr> <%i++; }%> <div class="abstractWriteup"><textarea name="abstract"></textarea> <input type="submit" value="Add Spotlight"></div> </table> </form> Thanks in Advance Dean

  Hi,thanks in advance, I have the code in which i want to find out the greatest number from six numbers, the code as follows, if( (pixels->r == 244 || pixels->g == 242 || pixels->b == 245) || (pixels->r == 236 || pixels->g == 235 || pixels->b == 233) || (pixels->r == 250 || pixels->g == 249 || pixels->b == 247) || (pixels->r == 253 || pixels->g == 251 || pixels->b == 230) || (pixels->r == 253 || pixels->g == 246 || pixels->b == 230) || (pixels->r == 254 || pixels->g == 247 || pixels->b == 229)) { numberOfPixels1++; NSLog( @"Pixel data1 %d", numberOfPixels1); } if( (pixels->r == 250 || pixels->g == 240 || pixels->b == 239) ||(pixels->r == 243 || pixels->g == 234 || pixels->b == 229) || (pixels->r == 244 || pixels->g == 241 || pixels->b == 234) || (pixels->r == 251 || pixels->g == 252 || pixels->b == 244) || (pixels->r == 252 || pixels->g == 248 || pixels->b == 237) || (pixels->r == 254 || pixels->g == 246 || pixels->b == 225)) { numberOfPixels2++; NSLog( @"Pixel data2 %d", numberOfPixels2); } if( (pixels->r == 255 || pixels->g == 249 || pixels->b == 225) ||(pixels->r == 255 || pixels->g == 249 || pixels->b == 225) || (pixels->r == 241 || pixels->g == 231 || pixels->b == 195) || (pixels->r == 239 || pixels->g == 226 || pixels->b == 173) || (pixels->r == 224 || pixels->g == 210 || pixels->b == 147) || (pixels->r == 242 || pixels->g == 226 || pixels->b == 151)) { numberOfPixels3++; NSLog( @"Pixel data3 %d", numberOfPixels3); } if( (pixels->r == 235 || pixels->g == 214 || pixels->b == 159) ||(pixels->r == 235 || pixels->g == 217 || pixels->b == 133) || (pixels->r == 227 || pixels->g == 196 || pixels->b == 103) || (pixels->r == 225 || pixels->g == 193 || pixels->b == 106) || (pixels->r == 223 || pixels->g == 193 || pixels->b == 123) || (pixels->r == 222 || pixels->g == 184 || pixels->b == 119)) { numberOfPixels4++; NSLog( @"Pixel data4 %d", numberOfPixels4); } if( (pixels->r == 199 || pixels->g == 164 || pixels->b == 100) ||(pixels->r == 188 || pixels->g == 151 || pixels->b == 98) || (pixels->r == 156 || pixels->g == 107 || pixels->b == 67) || (pixels->r == 142 || pixels->g == 88 || pixels->b == 62) || (pixels->r == 121 || pixels->g == 77 || pixels->b == 48) || (pixels->r == 100 || pixels->g == 49 || pixels->b == 22)) { numberOfPixels5++; NSLog( @"Pixel data5 %d", numberOfPixels5); } if( (pixels->r == 101 || pixels->g == 48 || pixels->b == 32) ||(pixels->r == 96 || pixels->g == 49 || pixels->b == 33) || (pixels->r == 87 || pixels->g == 50 || pixels->b == 41) || (pixels->r == 64 || pixels->g == 32 || pixels->b == 21) || (pixels->r == 49 || pixels->g == 37 || pixels->b == 41) || (pixels->r == 27 || pixels->g == 28 || pixels->b == 46)) { numberOfPixels6++; NSLog( @"Pixel data6 %d", numberOfPixels6); } I have to find out greatest from numberOfPixels1....numberOfPixels6 from above code. There are any optimum way to find out the greatest number?

• [How-to] Make a working xml file in php (encoding properly) to export data from online database to i

  - by gotye

  Hey guys, I am trying to make an xml file to export my data from my database to my iphone. Each time I create a new post, I need to execute a php file to create a xml file containing the latest post ;) Okay so far ? :D Here is current php code ... but my nsxmlparser gives me an error code (33 - String is not started). I have no idea what kind of php functions I have to use ... <?php // Èdition du dÈbut du fichier XML $xml .= '<?xml version=\"1.0\" encoding=\"UTF-8\"?>'; $sml .= '<channel>'; $xml .= '<title>Infonul</title>'; $xml .= '<link>aaa</link>'; $xml .= '<description>aaa</description>'; // connexion a la base (mettre ‡ jour le mdp) $connect = mysql_connect('...-12','...','...'); /* selection de la base de donnÈe mysql */ mysql_select_db('...'); // selection des 20 derniËres news $res=mysql_query("SELECT u.display_name as author,p.post_date as date,p.comment_count as commentCount, p.post_content as content,p.post_title as title FROM wp_posts p, wp_users u WHERE p.post_status = 'publish' and p.post_type = 'post' and p.post_author = u.id ORDER BY p.id DESC LIMIT 0,20"); // extraction des informations et ajout au contenu while($tab=mysql_fetch_array($res)){ $title=$tab[title]; $author=$tab[author]; $content=$tab[content]; //html stuff $commentCount=$tab[commentCount]; $date=$tab[date]; $xml .= '<item>'; $xml .= '<title>'.$title.'</title>'; $xml .= '<content><![CDATA['.$content.']]></content>'; $xml .= '<date>'.$date.'</date>'; $xml .= '<author>'.$author.'</author>'; $xml .= '<commentCount>'.$commentCount.'</commentCount>'; $xml .= '</item>'; } // Èdition de la fin du fichier XML $xml .= '</channel>'; $xml = utf8_encode($xml); echo $xml; // Ècriture dans le fichier if ($fp = fopen("20news.xml",'w')) { fputs($fp,$xml); fclose($fp); } //mysql_close(); ?> I noticed a few things when i open 20news.xml in my browser : I got squares instead of single quotes ... I can't see <[CDATA[ but ]] is clearly visible ... why ?!? Thanks for any input ;) Gotye.

• live search with Jquery

  - by user272899

  Hello! I am trying to implement a live search on my site. I am using a script somebody has already created. http://www.reynoldsftw.com/2009/03/live-mysql-database-search-with-jquery/ I have got the Jquery, css, html working correctly but am having troubles with the php. I need to change it to contain my database information but everytime I do I recieve an error: Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\search.php on line 33 These are the details of my database: database name: development table name: links Columns: id, sitename, siteurl, description, category This is the php script <?php $dbhost = "localhost"; $dbuser = "root"; $dbpass = "password"; $dbname = "links"; $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql'); mysql_select_db($dbname); if(isset($_GET['query'])) { $query = $_GET['query']; } else { $query = ""; } if(isset($_GET['type'])) { $type = $_GET['type']; } else { $query = "count"; } if($type == "count") { $sql = mysql_query("SELECT count(url_id) FROM urls WHERE MATCH(url_url, url_title, url_desc) AGAINST('$query' IN BOOLEAN MODE)"); $total = mysql_fetch_array($sql); $num = $total[0]; echo $num; } if($type == "results") { $sql = mysql_query("SELECT url_url, url_title, url_desc FROM urls WHERE MATCH(url_url, url_title, url_desc) AGAINST('$query' IN BOOLEAN MODE)"); while($array = mysql_fetch_array($sql)) { $url_url = $array['url_url']; $url_title = $array['url_title']; $url_desc = $array['url_desc']; echo "<div class=\"url-holder\"><a href=\"" . $url_url .

• SET game odds simulation (MATLAB)

  - by yuk

  Here is an interesting problem for your weekend. :) I recently find the great card came - SET. Briefly, there are 81 cards with the four features: symbol (oval, squiggle or diamond), color (red, purple or green), number (one, two or three) or shading (solid, striped or open). The task is to find (from selected 12 cards) a SET of 3 cards, in which each of the four features is either all the same on each card or all different on each card (no 2+1 combination). In my free time I've decided to code it in MATLAB to find a solution and to estimate odds of having a set in randomly selected cards. Here is the code: %% initialization K = 12; % cards to draw NF = 4; % number of features (usually 3 or 4) setallcards = unique(nchoosek(repmat(1:3,1,NF),NF),'rows'); % all cards: rows - cards, columns - features setallcomb = nchoosek(1:K,3); % index of all combinations of K cards by 3 %% test tic NIter=1e2; % number of test iterations setexists = 0; % test results holder % C = progress('init'); % if you have progress function from FileExchange for d = 1:NIter % C = progress(C,d/NIter); % cards for current test setdrawncardidx = randi(size(setallcards,1),K,1); setdrawncards = setallcards(setdrawncardidx,:); % find all sets in current test iteration for setcombidx = 1:size(setallcomb,1) setcomb = setdrawncards(setallcomb(setcombidx,:),:); if all(arrayfun(@(x) numel(unique(setcomb(:,x))), 1:NF)~=2) % test one combination setexists = setexists + 1; break % to find only the first set end end end fprintf('Set:NoSet = %g:%g = %g:1\n', setexists, NIter-setexists, setexists/(NIter-setexists)) toc 100-1000 iterations are fast, but be careful with more. One million iterations takes about 15 hours on my home computer. Anyway, with 12 cards and 4 features I've got around 13:1 of having a set. This is actually a problem. The instruction book said this number should be 33:1. And it was recently confirmed by Peter Norvig. He provides the Python code, but I didn't test it. So can you find an error?

• ArithmeticException thrown during BigDecimal.divide

  - by polygenelubricants

  I thought java.math.BigDecimal is supposed to be The Answer™ to the need of performing infinite precision arithmetic with decimal numbers. Consider the following snippet: import java.math.BigDecimal; //... final BigDecimal one = BigDecimal.ONE; final BigDecimal three = BigDecimal.valueOf(3); final BigDecimal third = one.divide(three); assert third.multiply(three).equals(one); // this should pass, right? I expect the assert to pass, but in fact the execution doesn't even get there: one.divide(three) causes ArithmeticException to be thrown! Exception in thread "main" java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result. at java.math.BigDecimal.divide It turns out that this behavior is explicitly documented in the API: In the case of divide, the exact quotient could have an infinitely long decimal expansion; for example, 1 divided by 3. If the quotient has a non-terminating decimal expansion and the operation is specified to return an exact result, an ArithmeticException is thrown. Otherwise, the exact result of the division is returned, as done for other operations. Browsing around the API further, one finds that in fact there are various overloads of divide that performs inexact division, i.e.: final BigDecimal third = one.divide(three, 33, RoundingMode.DOWN); System.out.println(three.multiply(third)); // prints "0.999999999999999999999999999999999" Of course, the obvious question now is "What's the point???". I thought BigDecimal is the solution when we need exact arithmetic, e.g. for financial calculations. If we can't even divide exactly, then how useful can this be? Does it actually serve a general purpose, or is it only useful in a very niche application where you fortunately just don't need to divide at all? If this is not the right answer, what CAN we use for exact division in financial calculation? (I mean, I don't have a finance major, but they still use division, right???).
