  • Centering Text Horizontally and Vertically in LaTeX

    - by Paul
    I would like to produce the following: a b xxxxx xxxxx 1 xxxxx xxxxx xxxxx xxxxx xxxxx xxxxx 2 xxxxx xxxxx xxxxx xxxxx Where the blocks of 'x's are images, and 'a', 'b', '1' and '2' are text. Here are my two attempts so far: \begin{figure} \begin{center} \begin{tabular}{ccc} & a & b \\ 1 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\ 2 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\ \end{tabular} \end{center} \end{figure} Which produces: a b xxxxx xxxxx xxxxx xxxxx 1 xxxxx xxxxx xxxxx xxxxx xxxxx xxxxx 2 xxxxx xxxxx And \begin{figure} \begin{center} \begin{tabular}{m{1cm}m{6cm}m{6cm}} & a & b \\ 1 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\ 2 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\ \end{tabular} \end{center} \end{figure} Which produces: a b xxxxx xxxxx 1 xxxxx xxxxx xxxxx xxxxx xxxxx xxxxx 2 xxxxx xxxxx xxxxx xxxxx

    - by Paul Suart
    I have the following route: routes.MapRoute( "Search", // Route name "Search/{affiliateId}", // URL with parameters new { controller = "Syndication", action = "Search" } // Parameter defaults ); Is there a way I can ensure "affiliateId" is a valid Guid? I'm using MVCContrib elsewhere in my site and I'm fairly it provides a way to implement this kind of constraint.... I just don't know what it is!

  • Gotchas INSERTing into SQLite on Android?

    - by paul.meier
    Hi friends, I'm trying to set up a simple SQLite database in Android, handling the schema via a subclass of SQLiteOpenHelper. However, when I query my tables, the columns I think I've inserted are never present. Namely, in SQLiteOpenHelper's onCreate(SQLiteDatabase db) method, I use db.execSQL() to run CREATE TABLE commands, then have tried both db.execSQL and db.insert() to run INSERT commands on the tables I've just created. This appears to run fine, but when I try to query them I always get 0 rows returned (for debugging, the queries I'm running are simple SELECT * FROM table and checking the Cursor's getCount()). Anybody run into anything like this before? These commands seem to run on command-line sqlite3. Are they're gotchas that I'm missing (e.g. INSERTS must/must not be semicolon terminated, or some issue involving multiple tables)? I've attached some of the code below. Thanks for your time, and let me know if I can clarify further. @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+ LEVEL_TABLE +" (" + " "+ _ID +" INTEGER PRIMARY KEY AUTOINCREMENT," + " level TEXT NOT NULL,"+ " rows INTEGER NOT NULL,"+ " cols INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ DYNAMICS_TABLE +" (" + " level_id INTEGER NOT NULL," + " row INTEGER NOT NULL,"+ " col INTEGER NOT NULL,"+ " type INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ SCORE_TABLE +" (" + " level_id INTEGER NOT NULL," + " score INTEGER NOT NULL,"+ " date_achieved DATE NOT NULL,"+ " name TEXT NOT NULL);"); this.enterFirstLevel(db); } And a sample of the insert code I'm currently using, which gets called in enterFirstLevel() (some values hard-coded just to get it running...): private void insertDynamic(SQLiteDatabase db, int row, int col, int type) { ContentValues values = new ContentValues(); values.put("level_id", "1"); values.put("row", Integer.toString(row)); values.put("col", Integer.toString(col)); values.put("type", Integer.toString(type)); db.insertOrThrow(DYNAMICS_TABLE, "col", values); } Finally, query code looks like this: private Cursor fetchLevelDynamics(int id) { SQLiteDatabase db = this.leveldata.getReadableDatabase(); try { String fetchQuery = "SELECT * FROM " + DYNAMICS_TABLE; String[] queryArgs = new String[0]; Cursor cursor = db.rawQuery(fetchQuery, queryArgs); Activity activity = (Activity) this.context; activity.startManagingCursor(cursor); return cursor; } finally { db.close(); } }

  • How to embed cover art in an MP3 file so that the iPhone player displays it when downloaded

    - by Paul Dixon
    I want to be able to provide a URL to a music track, and when that track is played on an iPhone, to show the cover art. I've tried embedding the cover art as an ID3 v2.3 tag, and while desktop players like VLC and Windows Media Player can see it, it seems the iPhone doesn't. Is this possible? Does anyone know of a way to achieve this - preferably a method which can be automated? Edit: this may not be possible - even if I add cover art with iTunes, the resulting file will still not have the coverart displayed when played as a download :(

  • XSLT Transforming sequential XML to hierarchical XML

    - by Jean-Paul Smit
    I have a requirement to transform a sequential XML node list into a hierarchical, but I run into some XSLT specific knowledge gap. The input XML contains articles, colors and sizes. In the sample below 'Record1' is an article, 'Record2' represents a color and 'Record3' are the sizes. The number of colors and sizes (record2 and record3) elements can vary. <root> <Record1>...</Record1> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record1>...</Record1> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> </root> All fields are on the same hierarchical level, but still I have to create this structure as output: <root> <article> -> Record1 <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> </article> <article> -> Record1 <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> </article> </root> I've tried to iterate the nodes sequentially but for example the 'article' (=record1) node tag needs to remain unclosed while 'color' (=record2) nodes are processed. The same counts for processing 'size' (=record3) having 'color' unclosed, but that is not allowed by XSLT. My next idea was to call a template for every article, color and size level, but I don't know how to select for example all 'record3' nodes between the current 'record2' and the next article represented by 'record1'. I've also got a limitation on the XSLT version because I need this transformation in BizTalk Server which only supports XSLT 1.0 Can someone push me in the right direction?

  • How to adjust video recording brightness?

    - by Paul
    When I record videos in low-light conditions on my Motorola Droid results are poor... very dark images. On my old phone, an LG Dare, recording in low light works better thanks to a brightness adjustment in the video recorder which can be set manually... Android does not have a similar brightness adjustment when recording video. Does anyone have suggestions for how to adjust the brightness using Android's APIs? I have searched the official APIs, but I cannot find a way to control brightness.

    - by Paul Sasik
    We have a .NET app that needs to examine a folder that may contain COM libraries (DLL and OCX.) When we do encounter a COM library one thing we need to accomplish is to extract the GUID from the COM DLL or OCX. Is there a straightforward way to do this with .NET without using 3rd party libraries?

  • Grails: Querying Associations causes groovy.lang.MissingMethodException

    - by Paul
    Hi, I've got an issue with Grails where I have a test app with: class Artist { static constraints = { name() } static hasMany = [albums:Album] String name } class Album { static constraints = { name() } static hasMany = [ tracks : Track ] static belongsTo = [artist: Artist] String name } class Track { static constraints = { name() lyrics(nullable: true) } Lyrics lyrics static belongsTo = [album: Album] String name } The following query (and a more advanced, nested association query) works in the Grails Console but fails with a groovy.lang.MissingMethodException when running the app with 'run-app': def albumCriteria = tunehub.Album.createCriteria() def albumResults = albumCriteria.list { like("name", receivedAlbum) artist { like("name", receivedArtist) } // Fails here maxResults(1) } Stacktrace: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (tunehub.LyricsService$_getLyrics_closure1_closure2) values: [tunehub.LyricsService$_getLyrics_closure1_closure2@604106] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), trim() at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy:61) at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy) (...truncated...)

  • Can't display Tool Tips in VC++6.0

    - by Paul
    I'm missing something fundamental, and probably both simple and obvious. My issue: I have a view (CPlaybackView, derived from CView). The view displays a bunch of objects derived from CRectTracker (CMpRectTracker). These objects each contain a floating point member. I want to display that floating point member when the mouse hovers over the CMpRectTracker. The handler method is never executed, although I can trace through OnIntitialUpdate, PreTranslateMessage, and OnMouseMove. This is in Visual C++ v. 6.0. Here's what I've done to try to accomplish this: 1. In the view's header file: public: BOOL OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult); private: CToolTipCtrl m_ToolTip; CMpRectTracker *m_pCurrentRectTracker;//Derived from CRectTracker 2. In the view's implementation file: a. In Message Map: ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnToolTipNeedText) b. In CPlaybackView::OnInitialUpdate: if (m_ToolTip.Create(this, TTS_ALWAYSTIP) && m_ToolTip.AddTool(this)) { m_ToolTip.SendMessage(TTM_SETMAXTIPWIDTH, 0, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_AUTOPOP, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_INITIAL, 200); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_RESHOW, 200); } else { TRACE("Error in creating ToolTip"); } this->EnableToolTips(); c. In CPlaybackView::OnMouseMove: if (::IsWindow(m_ToolTip.m_hWnd)) { m_pCurrentRectTracker = NULL; m_ToolTip.Activate(FALSE); if(m_rtMilepostRect.HitTest(point) >= 0) { POSITION pos = pDoc->m_rtMilepostList.GetHeadPosition(); while(pos) { CMpRectTracker tracker = pDoc->m_rtMilepostList.GetNext(pos); if(tracker.HitTest(point) >= 0) { m_pCurrentRectTracker = &tracker; m_ToolTip.Activate(TRUE); break; } } } } d. In CPlaybackView::PreTranslateMessage: if (::IsWindow(m_ToolTip.m_hWnd) && pMsg->hwnd == m_hWnd) { switch(pMsg->message) { case WM_LBUTTONDOWN: case WM_MOUSEMOVE: case WM_LBUTTONUP: case WM_RBUTTONDOWN: case WM_MBUTTONDOWN: case WM_RBUTTONUP: case WM_MBUTTONUP: m_ToolTip.RelayEvent(pMsg); break; } } e. Finally, the handler method: BOOL CPlaybackView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult) { BOOL bHandledNotify = FALSE; CPoint CursorPos; VERIFY(::GetCursorPos(&CursorPos)); ScreenToClient(&CursorPos); CRect ClientRect; GetClientRect(ClientRect); // Make certain that the cursor is in the client rect, because the // mainframe also wants these messages to provide tooltips for the // toolbar. if (ClientRect.PtInRect(CursorPos)) { TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR; CString str; str.Format("%f", m_pCurrentRectTracker->GetMilepost()); ASSERT(str.GetLength() < sizeof(pTTT->szText)); ::strcpy(pTTT->szText, str); bHandledNotify = TRUE; } return bHandledNotify; }

  • Unit testing Google wave robots in Java

    Any tips or best practices for unit testing Google Wave robots written in Java? I'm expecting to deploy on AppEngine, if that helps. I'm a fan of TDD but new to both Wave Robots and AppEngine, so I'm hoping to use TDD to help me explore the design space.

  • VS2010 debugger always breaks

  • Is there any benefit to my rather quirky character sizing convention?

    - by Paul Alan Taylor
    I love things that are a power of 2. I celebrated my 32nd birthday knowing it was the last time in 32 years I'd be able to claim that my age was a power of 2. I'm obsessed. It's like being some Z-list Batman villain, except without the colourful adventures and a face full of batarangs. I ensure that all my enum values are powers of 2, if only for future bitwise operations, and I'm reasonably assured that there is some purpose (even if latent) for doing it. Where I'm less sure, is in how I define the lengths of database fields. Again, I can't help it. Everything ends up being a power of 2. CREATE TABLE Person ( PersonID int IDENTITY PRIMARY KEY ,Firstname varchar(64) ,Surname varchar(128) ) Can any SQL super-boffins who know about the internals of how stuff is stored and retrieved tell me whether there is any benefit to my inexplicable obsession? Is it more efficient to size character fields this way? Can anyone pop in with an "actually, what you're doing works because ....."? I suspect I'm just getting crazier in my older age, but it'd be nice to know that there is some method to my madness.

  • What tools do you use when generating markup from mockups?

    - by Paul
    So I endeavor to spend most of time on the app server side of things but time to time I need to get my hands dirty and generate markup/css/js from a wireframe or mockup. As far as tools go, Ive found browsershots and Litmus app helpful and of course, vm's as well for checking things out live in ie-{6,7,8}. Otherwise I do the heavy lifting in vim. For generating new markup thats not tied to a target design I think some of the css frameworks & tools like sass look useful but Im skeptical of their utility when needing to generate markup to match a photoshop design. So what tips / tools do you keep in your markup generating utility belt when building solid markup from designs? My list so far: Browsershots Browserlab.adobe.com Haml / Less / Sass (not used but will probably explore)

  • VB.NET For Each steps into loop body for an IEnumerable collection! How? Why?

    - by Paul Sasik
    This is weird. I have a class that inherits from IEnumrable whose Count property is reporting 0 (zero) elements but the For Each loop steps into the loop body and tries to use the variable where it should just be moving on. My code: On Error Resume Next Dim d As Foo For Each d In fooCollection ' use d and throws an exception Next d Weirder still, every time d is accessed i get an exception thrown in the output window: A first chance exception of type 'System.NullReferenceException' but i'm not stopping on the exception (not in a try/catch block). Is "On Error Resume Next" causing this weirdness? Weirdness found: Per Rowland's and JohnH's comments i checked the Foo class: The GetEnumerator method inside of Foo didn't actually return anything! It had an empty body. That coupled with the On Error Resume Next before the loop caused the havoc! Wow this was ugly. Thanks for the clues guys!

  • Adding business logic to a domain class using a getter style method name

    - by Richard Paul
    I'm attempting to add a method to a grails domain class, e.g. class Item { String name String getReversedName() { name.reverse() } } When I attempt to load the application using grails console I get the following error: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory':Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property reversedName in class Item ... 18 more It looks like Hibernate is interpreting getReversedName() as a getter for a property, however in this case it is a derived field and hence should not be persisted. Obviously in my actual code the business logic I'm exposing is more complex but it isn't relevant to this question. I want to be able to call item.reversedName in my code/gsps. How can I provide property (getter) access to a method in a Grails domain class without Grails attempting to map it with Hibernate?
