  • How can i edit OSGi bundles manifest file in Netbeans 6.9?

    - by Deniz Acay
    I'm using Netbeans 6.9 RC2 and Maven OSGi Bundle project template. Actually i dont want to test my bundles in Netbeans environment so i copy the jar file to the OSGi container directory and install it from command line. But when i want to see its headers from OSGi console, i see a lot of Netbeans related unnecessary stuff. Is it possible to edit the contents of the manifest file in Netbeans?

  • sql 2008 express connection problems

    - by user163457
    Hi, I've just installed a fresh copy of SQL 2008 Express. before I did anything I opened Management Studio and successfully connected using Window Authentication. However I tried to run the following on the command line "telnet localhost 1433" and got the error "Could not open connection to the host, on port 1433: Connect failed" I checked netstat and there is nothing listening on port 1433. Before I go any further, is there a problem with the install? thanks, Shane

  • Flex 4 / Flash 4 Add to Current State

    - by user163757
    I am having a little difficulty working with states in Flex (or Flash) 4. Lets say that my application has three states; the default (base) state, state 1, and state 2. State 1 should always be based on the base state, that's easy enough to accomplish. However, I would like state 2 to be based on the current state (either base or state 1). I can't for the life of me figure it out. I tried setting the basedOn property of state 1 to "this.currentState", but that just crashes my browser. <s:states> <s:State name="default"/> <s:State name="state1"/> <s:State name="state2" basedOn="{this.currentState}"/> </s:states> <s:TitleWindow id="configWindow" includeIn="state1" width="250" height="100%" close="configWindow_closeHandler(event)"/> <s:Panel id="settings" includeIn="state2" width="200" height="200"/>

  • 8bpp Bitmap format on the Compact Framework

    - by Kieran
    Hi friends. I am messing around with Conway's Game of Life - http://en.wikipedia.org/wiki/Conway's_Game_of_Life I started out coding algorithmns for winforms and now want to port my work onto windows mobile 6.1 (compact framework). I came across an article by Jon Skeet where he compared several different algorithmns for calculating next generations in the game. He used an array of bytes to store a cells state (alive or dead) and then he would copy this array to an 8bpp bitmap. For each new generation, he works out the state of each byte, then copies the array to a bitmap, then draws that bitmap to a picturebox. void CreateInitialImage() { bitmap = new Bitmap(Width, Height, PixelFormat.Format8bppIndexed); ColorPalette palette = bitmap.Palette; palette.Entries[0] = Color.Black; palette.Entries[1] = Color.White; bitmap.Palette = palette; } public Image Render() { Rectangle rect = new Rectangle(0, 0, Width, Height); BitmapData bmpData = bitmap.LockBits(rect, ImageLockMode.ReadWrite, bitmap.PixelFormat); Marshal.Copy(Data, 0, bmpData.Scan0, Data.Length); bitmap.UnlockBits(bmpData); return bitmap; } His code above is beautifully simple and very fast to render. Jon is using Windows Forms but now I want to port my own version of this onto Windows Mobile 6.1 (Compact Framework) but . . . .there is no way to format a bitmap to 8bpp in the cf. Can anyone suggest a way of rendering an array of bytes to a drawable image in the CF. This array is created in code on the fly (it is NOT loaded from an image file on disk). I basically need to store an array of cells represented by bytes, they are either alive or dead and I then need to draw that array as an image. The game is particularly slow on the CF so I need to implement clever optimised algoritmns but also need to render as fast as possible and the above solution would be pretty dam perfect if only it was available on the compact framework. Many thanks for any help Any suggestions?

  • Break a class in twain, or impose an interface for restricted access?

    - by bedwyr
    What's the best way of partitioning a class when its functionality needs to be externally accessed in different ways by different classes? Hopefully the following example will make the question clear :) I have a Java class which accesses a single location in a directory allowing external classes to perform read/write operations to it. Read operations return usage stats on the directory (e.g. available disk space, number of writes, etc.); write operations, obviously, allow external classes to write data to the disk. These methods always work on the same location, and receive their configuration (e.g. which directory to use, min disk space, etc.) from an external source (passed to the constructor). This class looks something like this: public class DiskHandler { public DiskHandler(String dir, int minSpace) { ... } public void writeToDisk(String contents, String filename) { int space = getAvailableSpace(); ... } public void getAvailableSpace() { ... } } There's quite a bit more going on, but this will do to suffice. This class needs to be accessed differently by two external classes. One class needs access to the read operations; the other needs access to both read and write operations. public class DiskWriter { DiskHandler diskHandler; public DiskWriter() { diskHandler = new DiskHandler(...); } public void doSomething() { diskHandler.writeToDisk(...); } } public class DiskReader { DiskHandler diskHandler; public DiskReader() { diskHandler = new DiskHandler(...); } public void doSomething() { int space = diskHandler.getAvailableSpace(...); } } At this point, both classes share the same class, but the class which should only read has access to the write methods. Solution 1 I could break this class into two. One class would handle read operations, and the other would handle writes: // NEW "UTILITY" CLASSES public class WriterUtil { private ReaderUtil diskReader; public WriterUtil(String dir, int minSpace) { ... diskReader = new ReaderUtil(dir, minSpace); } public void writeToDisk(String contents, String filename) { int = diskReader.getAvailableSpace(); ... } } public class ReaderUtil { public ReaderUtil(String dir, int minSpace) { ... } public void getAvailableSpace() { ... } } // MODIFIED EXTERNALLY-ACCESSING CLASSES public class DiskWriter { WriterUtil diskWriter; public DiskWriter() { diskWriter = new WriterUtil(...); } public void doSomething() { diskWriter.writeToDisk(...); } } public class DiskReader { ReaderUtil diskReader; public DiskReader() { diskReader = new ReaderUtil(...); } public void doSomething() { int space = diskReader.getAvailableSpace(...); } } This solution prevents classes from having access to methods they should not, but it also breaks encapsulation. The original DiskHandler class was completely self-contained and only needed config parameters via a single constructor. By breaking apart the functionality into read/write classes, they both are concerned with the directory and both need to be instantiated with their respective values. In essence, I don't really care to duplicate the concerns. Solution 2 I could implement an interface which only provisions read operations, and use this when a class only needs access to those methods. The interface might look something like this: public interface Readable { int getAvailableSpace(); } The Reader class would instantiate the object like this: Readable diskReader; public DiskReader() { diskReader = new DiskHandler(...); } This solution seems brittle, and prone to confusion in the future. It doesn't guarantee developers will use the correct interface in the future. Any changes to the implementation of the DiskHandler could also need to update the interface as well as the accessing classes. I like it better than the previous solution, but not by much. Frankly, neither of these solutions seems perfect, but I'm not sure if one should be preferred over the other. I really don't want to break the original class up, but I also don't know if the interface buys me much in the long run. Are there other solutions I'm missing?

  • Multiple login locations for an online app.

    - by Goro
    Hello, I am working on a browser based application that will have many users. The catch is that every user should have their own customized login page, but the actual application is the same for everyone, and needs to be in a central location. What is the most secure way of doing this? Would it make more sense to have a copy of the application for each user, and keep the database centralized? The projected number of users is not very high, probably around 20-80. Thank you,

  • PDF Report generation

    - by IniTech
    EDIT : I completed this project using ABCpdf. For anyone interested, I love this product and their support is A+. Everything I listed as a 'Con' for the HTML - PDF solution was easily doable in ABCpdf. I've been charged with creating a data driven pdf report. After reviewing the plethora of options, I have narrowed it down to 2. I need you all to to help me decide, or offer alternatives I haven't considered. Here are the requirements: 100% Data driven Eventually PDF (a stop in HTML is fine, so long as it is converted) Can be run with multiple sets of data (the layout is always the same, the data is variable) Contains normal analysis-style copy (saved in DB with html markup) Contains tables (data for tables is generated at run-time) Header/Page # on each page Table of Contents .NET (VB or C#) Done quickly Now, because of the fact that the report is going to be generated with multiple sets of data, I don't think a stamped pdf template will work since I won't know how long or how many pages a certain piece of the report could require. So, I think my best options are: Programmatic creation using an iText-like solution. Generate in HTML and convert to PDF using a third-party application (ABCPdf is the tool I have played with so far) Both solutions have their pro's and con's. Programmatic solution: Pros: Flexible Easy page numbering/page header/table of contents Free Cons: Time consuming (to write a layer on top of iText to do what I need and keep maintainable) Since the copy is already stored in the db with html markup, I would have to parse through the data before I place it into the pdf, ensuring I don't have to break the paragraph into chunks so I can apply bold, italic, underline, etc. to specific phrases. This seems like a huge PITA, and I hope I am wrong about that assumption. HTML - PDF Pros: Easy to generate from db (no parsing necessary) Many tools for conversion Uses technology I am already familiar with Built-in "Print Preview" - not a req, but nice Cons: (Edited after project completion. All of my assumptions were incorrect and ABCpdf is awesome) 1. Almost impossible to generate page headers - Not True 2. Very difficult to generate page numbers Not True 3. Nearly impossible to generate table of contents Not True 4. (Cross-browser support isn't a con; Since its internal, I can dictate what browser to use) 5. Conversion tool quirks - may not convert exactly as rendered in browser Not True 6. Overall, I think it would be very hard to format the HTML exactly as I would want it to appear/convert to PDF. Not True That's it - I need the communitys help in deciding which way I should go. I might be wrong about some of my Pro/Con assumptions. If I am, please tell me. All thoughts and suggestions are welcome and appreciated. Thanks

  • Strange behaviour when posting CGEvent to PSN

    - by Ben Packard
    If I set up a loop that posts some keyboard events to a PSN, I find that it works fine except for when first launched. The event only seems to post when i do something with the mouse manually - even just moving it slightly. Here's the details, if they help. An external application has a list box of text lines, which I am reading by posting copy commands (and checking the pasteboard). Unfortunately this is my only way to get this text. Sometimes, the application pulls focus away from the list, which I can detect. When this happens, the most reliable way to return focus is by sending a mouse event to click on a text field directly above the list, then send a 'tab' keyboard event to shift the focus onto the list. So at launch, the loop runs fine, scrolling down the list and copying the text. When focus is shifted away, its is detected fine, and the events are sent to move focus back to the list. But nothing seems to happen. The loop continues detecting that focus has changed, but the events only work once I move the mouse. Or even just use the scroll wheel. Strange. Once this has happened the first time, it works fine - each time focus moves, the PSN events switch it back without me having to do anything at all. Here's the code that runs in the loop - verified as working: //copy to pasteboard - CMD-V e3 = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)8, true); CGEventSetFlags(e3, kCGEventFlagMaskCommand); CGEventPostToPSN(&psn, e3); CFRelease(e3); e4 = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)8, false); CGEventPostToPSN(&psn, e4); CFRelease(e4); //move cursor down e1 = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)125, true); CGEventPostToPSN(&psn, e1); CFRelease(e1); e2 = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)125, false); CGEventPostToPSN(&psn, e2); CFRelease(e2); And here's where I switch focus, also working (except when first required): //click in text input box - point is derived earlier e6 = CGEventCreateMouseEvent(NULL, kCGEventLeftMouseDown, point, 0); CGEventPostToPSN(&psn, e6); CFRelease(e6); e7 = CGEventCreateMouseEvent(NULL, kCGEventLeftMouseUp, point, 0); CGEventPostToPSN(&psn, e7); CFRelease(e7); //press tab key to move to chat log table CGEventRef e = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)48, true); //CGEventPost(kCGSessionEventTap, e); CGEventPostToPSN(&psn, e); CFRelease(e); CGEventRef e11 = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)48, false); CGEventPostToPSN(&psn, e11); CFRelease(e11);

  • How to get root as '/' with Kohana3, base_url and mod rewrite.

    - by Drew
    Hi all! I've only just started using Kohana ( 3 hours ago), and so far it's blown my socks off (and I'm wearing slippers, so that's quite impressive). Right now, I have a controller 'Controller_FrontPage' with associated views and models and I'm trying to get it accesible from the root of my website (eg, http://www.mysite.com/). If I edit the default controller in the bootstrap from: Route::set('default', '(<controller>(/<action>(/<id>)))') ->defaults(array( 'controller' => 'welcome', 'action' => 'index', )); to 'controller' => '', I get an error, could not find controller_ (which makes sense), and if I change it to 'controller' => '/', I get an error, could not find controller_/ (which also makes sense). If I set 'controller' => 'FrontPage', everything works fine, but all my links (html::anchor(...)) point to http://www.mysite.com/FrontPage/*. Is there a way to have all the anchors point to http://www.mysite.com/*?

    There was this old sql server tool called Lectoneth or something like that, you'd put sql queries in it, and it would rewrite it for you. I think quest bought them out, but I can't find where to download a free copy of that software. Really helps when you have no dba, and have lots of sql queries to rewrite. Thanks Craig

  • XSL transformation and special XML entities escaping

    - by Tomas R
    I have an XML file which is transformed with XSL. Some elements have to be changed, some have to be left as is - specifically, text with entities &quot;, &amp;, &apos;, &lt;, &gt; should be left as is, and in my case &quot; and &apos; are changed to " and ' accordingly. Test XML: <?xml version="1.0" encoding="UTF-8" ?> <root> <element> &quot; &amp; &apos; &lt; &gt; </element> </root> transformation file: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="xml" encoding="UTF-8" omit-xml-declaration="no" indent="no" /> <xsl:template match="element"> <xsl:copy> <xsl:value-of disable-output-escaping="no" select="." /> </xsl:copy> </xsl:template> </xsl:stylesheet> result: <?xml version="1.0" encoding="UTF-8"?> <element> " &amp; ' &lt; &gt; </element> desired result: <?xml version="1.0" encoding="UTF-8"?> <element> &quot; &amp; &apos; &lt; &gt; </element> I have 2 questions: why does some of those entities are transformed and other not? how can I get a desired result?

  • How do you tell if two wildcards overlap?

    Given two strings with * wildcards, I would like to know if a string could be created that would match both. For example, these two are a simple case of overlap: Hello*World Hel* But so are all of these: *.csv reports*.csv reportsdump.csv Is there an algorithm published for doing this? Or perhaps a utility function in Windows or a library I might be able to call or copy?

  • Mix of Arabic and English causes problems in JTextArea (Java)

    - by Dan
    I have a JTextArea which displays HTML of an Arabic web page. So it's essentially a mix of English and Arabic. In the JTextArea, with columns set to 30, certain text just disappears instead of wrapping properly. The weird thing is that if I copy the invisible text and paste it into Notepad, then I can see it in Notepad. If I change the number of columns to 40, everything displays fine. Any ideas?

  • Multiple jQuery UI buttons with same ID

    - by Mark Nolan
    There might be a really simple solution to this question, but i just don't see it! I have a page with a list of items. every item has the same jquery ui button (its inside a dialog and adds that item to a list). i identify the item via the parenting DIV holding the DB id. So far so good... The Problem is only the first button on the list works! The second, third etc. buttons don't show any reaction at all. The buttons all have the same id - as the list is dynamic and the same action is triggered with every click. Only the parenting ID changes. Heres the display part: <div id="2"> <div id="56"> <button id="add-audio-file" class="ui-button ui-state-default ui-corner-all">betty_2.mp3</button> </div> </div> <div id="2"> <div id="57"> <button id="add-audio-file" class="ui-button ui-state-default ui-corner-all">betty_3.mp3</button> </div> </div> And here comes the js Part: $('#add-audio-file').click(function() { assetID = $(this).parent('div').attr('id'); pageID = $(this).parent('div').parent('div').attr('id'); $.post( "modules/portfolio/serialize.php", {id : pageID, assetid : assetID, do : "add-audio-file"}, function(data, textStatus, xhr) { $('#dialog-add-audio').dialog('close'); } ); }); I am using jquery 1.4.2 and jquery ui 1.8rc3 Any ideas?

  • Struts2 Converting Enum Array fills array with single null value

    - by Kyle Partridge
    For a simple action class with these member variables: ... private TestConverterEnum test; private TestConverterEnum[] tests; private List<TestConverterEnum> tList; ... And a simple enum: public enum TestConverterEnum { A, B, C; } Using the default struts2 enum conversion, when I send the request like so: TestConterter.action?test=&tests=&tList=&b=asdf For test I get a null value, which is expected. For the Array and List, however, I get and Array (or list) with one null element. Is this what is expected? Is there a way to prevent this. We recently upgraded our struts2 version, and we had our own converters, which also don't work in this case, so I was hoping to use the default conversion method. We already have code that is validating these arrays for null and length, and I don't want to have to add another condition to these branches. Is there a way to prevent this bevavior?

  • C++ Switch won't compile with externally defined variable used as case

    - by C Nielsen
    I'm writing C++ using the MinGW GNU compiler and the problem occurs when I try to use an externally defined integer variable as a case in a switch statement. I get the following compiler error: "case label does not reduce to an integer constant". Because I've defined the integer variable as extern I believe that it should compile, does anyone know what the problem may be? Below is an example: test.cpp #include <iostream> #include "x_def.h" int main() { std::cout << "Main Entered" << std::endl; switch(0) { case test_int: std::cout << "Case X" << std::endl; break; default: std::cout << "Case Default" << std::endl; break; } return 0; } x_def.h extern const int test_int; x_def.cpp const int test_int = 0; This code will compile correctly on Visual C++ 2008. Furthermore a Montanan friend of mine checked the ISO C++ standard and it appears that any const-integer expression should work. Is this possibly a compiler bug or have I missed something obvious? Here's my compiler version information: Reading specs from C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/specs Configured with: ../gcc-3.4.5-20060117-3/configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry --disable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter --enable-hash-synchronization --enable-libstdcxx-debug Thread model: win32 gcc version 3.4.5 (mingw-vista special r3)
