  • Set scaleX property on a Sprite without altering the child inside

    - by grammar
    Is this possible? My site is set up with next and prev buttons on the right and left sides respectively, and as you roll over either of the hit areas around the buttons a Sprite fades in which contains a TextField that describes the next page. Said Sprite calls the StartDrag() method, so it follows the mouse within the bounds, which is all fine and dandy on the left side of the page. Adobe, however, seems to have forgotten to put a way to dynamically alter the registration point of a Sprite, MC, whatever else, so when you roll over the right side of the page, the sprite is displayed from the top left and is mostly off the stage. Trying to hack this problem I have tried numerous things ( classes written by others, other hacks) and the best that I have found is to use the scaleX method on the Sprite, changing the scale to -1. This, of course, makes the Sprite seem like it's reflected from its normal point, which means all its children show up backwards. Is there anyway I can use this hack without it altering the text? OR Does anyone know a different way to go about displaying a Sprite from another corner? Any way to make a Sprite fade in and follow the mouse on the LEFT HAND side of the mouse pointer? Thank you very much in advance. Here is a snippet to give an idea of what's happening: naxtPage.labelBG.scaleX = -1; nextPage.labelBG.startDrag( true, nextHitRect ); nextPage.labelBG.x = nextPage.labelBG.parent.mouseX; nextPage.labelBG.y = nextPage.labelBG.parent.mouseY; Cheers

  • Android Plugin in Eclipse 3.5 on Ubuntu 64bit got problems with properties

    - by Zordid
    Hi there! I got a huge problem with the Android Development Tools ADT running in Eclipse Galileo (3.5.1) on Ubuntu 9.10, 64bit. On this platform, I do not manage to see any property edit dialogs for layout properties. E.g. the one where you can select a string resource ID for text fields, or a drawable ID for image fields or backgrounds. Whenever I click on the ... button next to the property value - nothing happens, except this button disappears. Properties with a list of possible values, e.g. "wrap_content" or "fill_parent" are displayed in a dropdown box directly in the properties field. On a different system I work in a Windows environment with Eclipse 3.4 and the same ADT: no problems whatsoever, everything works fine, the dialogs come perfectly. Does anyone know what to do here? Where's the problem? Why does Eclipse not tell me that something goes wrong? Thanks! NEW DISCOVERIES: I found out that it might not even be an Android problem, but a general Eclipse problem that I can see with all version (Ganymede, Galileo, Helios) on my Linux (Ubuntu) system. It must be a simple UI problem: the button with ... next to the values does not receive the mouse click!! I managed to see the appropriate dialogs to edit the property values by doubleclicking the button - crazy, strange, ugly behavior! But why on earth does nobody else know about this problem - I cannot find anything else on the net about it! Could it be related to this strange "GDK native window problem" on Gnome? HELP!

  • Python C API from C++ app - know when to lock

    - by Alex
    Hi Everyone, I am trying to write a C++ class that calls Python methods of a class that does some I/O operations (file, stdout) at once. The problem I have ran into is that my class is called from different threads: sometimes main thread, sometimes different others. Obviously I tried to apply the approach for Python calls in multi-threaded native applications. Basically everything starts from PyEval_AcquireLock and PyEval_ReleaseLock or just global locks. According to the documentation here when a thread is already locked a deadlock ensues. When my class is called from the main thread or other one that blocks Python execution I have a deadlock. Python Cfunc1() - C++ func that creates threads internally which lead to calls in "my class", It stuck on PyEval_AcquireLock, obviously the Python is already locked, i.e. waiting for C++ Cfunc1 call to complete... It completes fine if I omit those locks. Also it completes fine when Python interpreter is ready for the next user command, i.e. when thread is calling funcs in the background - not inside of a native call I am looking for a workaround. I need to distinguish whether or not the global lock is allowed, i.e. Python is not locked and ready to receive the next command... I tried PyGIL_Ensure, unfortunately I see hang. Any known API or solution for this ? (Python 2.4)

  • [LaTeX] breaking an environment across pages - the smart way

    - by Flavius
    Hi I am using the exercise package to display exercises in a book. I have redefined some commands like this, which basically adds some space, a pencil, and two hrule's before and after the exercise: \renewcommand{\ExerciseHeader}{\vskip 1em\hrule\vskip 1em\centerline{\textbf{\large\smallpencil \ExerciseHeaderNB\ExerciseHeaderTitle% \ExerciseHeaderDifficulty\ExerciseHeaderOrigin\medskip}}} \makeatletter\def\endExerciseEnv{\termineliste{1}\@EndExeBox\vskip .5em\hrule\vskip 1em}\makeatother Now this works, but there's a small problem: There are situations where only the \hrule ends up being at the bottom of a page, and the rest of the exercise goes on the next page. There is also the opposite behavior: the entire exercise is on one page, except the \hrule in "endExerciseEnv", which is flushed to the next page. My question is: How to force the top hrule come either together with the header of the exercise (caption, title, whatever not) and at least the first two paragraphs (or \ExePath and a paragraph, or anything like that, but there must be at last "two things", so it doesn't look ugly), OR be flushed altogether, with the entire exercise? Similar question for the bottom hrule: How to force it have at least two items in front of it on the visible page where the hrule itself goes to? Any LaTeX guru who knows that? Addendum I have asked in the past LaTeX questions like this and I've got answers which required me to do stuff manually, like "insert a \vskip here and there" or such. Let me be clear: This is a book, there's lot of exercises, and I NEED it be done "automatically", by going the proper way of redeclaring commands & co.

  • function php with parameter 0

    - by Arnaud Ncy
    I have a function like this public function get_page($position) { switch ($position) { case "current": echo "current"; return $this->current_page; break; case "first": echo "first"; return $this->current_page >= 3 ? 1 : false; break; case "last": echo "last"; return $this->current_page <= $this->total_pages() - 2 ? ceil($this->count / $this->nb_items_to_show) : false; break; case "previous": echo "previous"; return $this->current_page - 1 >= 1 ? $this->current_page - 1 : false; break; case "next": echo "next"; return $this->current_page + 1 <= $this->total_pages() ? $this->current_page + 1 : false; break; case is_int($position): echo "int"; if ($position >= 1 && $position <= $this->total_pages()) { return $position; } else { return false; } break; default: echo "default"; return false; break; } } When I call the function, it works for every parameters except 0 and goes in "current" case in the switch. $paginator->get_page(0); If I call the function with quotes "0", it works. But the function could be called like this $paginator->get_page($paginator->get_page("current") - 2); How can I call the function with parameter 0 ?

  • 'Bank Switching' Sprites on old NES applications

    - by Jeffrey Kern
    I'm currently writing in C# what could basically be called my own interpretation of the NES hardware for an old-school looking game that I'm developing. I've fired up FCE and have been observing how the NES displayed and rendered graphics. In a nutshell, the NES could hold two bitmaps worth of graphical information, each with the dimensions of 128x128. These are called the PPU tables. One was for BG tiles and the other was for sprites. The data had to be in this memory for it to be drawn on-screen. Now, if a game had more graphical data then these two banks, it could write portions of this new information to these banks -overwriting what was there - at the end of each frame, and use it from the next frame onward. So, in old games how did the programmers 'bank switch'? I mean, within the level design, how did they know which graphic set to load? I've noticed that Mega Man 2 bankswitches when the screen programatically scrolls from one portion of the stage to the next. But how did they store this information in the level - what sprites to copy over into the PPU tables, and where to write them at? Another example would be hitting pause in MM2. BG tiles get over-written during pause, and then get restored when the player unpauses. How did they remember which tiles they replaced and how to restore them? If I was lazy, I could just make one huge static bitmap and just grab values that way. But I'm forcing myself to limit these values to create a more authentic experience. I've read the amazing guide on how M.C. Kids was made, and I'm trying to be barebones about how I program this game. It still just boggles my mind how these programmers accomplisehd what they did with what they had. EDIT: The only solution I can think of would be to hold separate tables that state what tiles should be in the PPU at what time, but I think that would be a huge memory resource that the NES wouldn't be able to handle.

  • Zend_Auth and database session SaveHandler

    - by takeshin
    I have created Zend_Auth adapter implementing Zend_Auth_Adapter_Interface (similar to Pádraic's adapter) and created simple ACL plugin. Everything works fine with default session handler. So far, so good. As a next step I have created custom Session SaveHandler to persist session data in the database. My implementation is very similar to this one from parables-demo. Seems that everything is working fine. Session data are properly saved to the database, session objects are serialized, but authentication does not work when I enable this custom SaveHandler. I have debugged the authentication and all works fine up till the next request, when the authentication data are lost. I suspected, that is has something to do with the fact, that I use $adapter->write($object) instead $adapter->write($string), but the same happens with strings. I'm bootstrapping Zend_Application_Resource_Session in the first Bootstrap method, as early as possible. Does Zend_Auth need any extra configuration to persist data in the database? Why the authentity is being lost?

  • Would anybody recommend learning J/K/APL?

    - by ozan
    I came across J/K/APL a few months ago while working my way through some project euler problems, and was intrigued, to say the least. For every elegant-looking 20 line python solution I produced, there'd be a gobsmacking 20 character J solution that ran in a tenth of the time. I've been keen to learn some basic J, and have made a few attempts at picking up the vocabulary, but have found the learning curve to be quite steep. To those who are familiar with these languages, would you recommend investing some time to learn one (I'm thinking J in particular)? I would do so more for the purpose of satisfying my curiosity than for career advancement or some such thing. Some personal circumstances to consider, if you care to: I love mathematics, and use it daily in my work (as a mathematician for a startup) but to be honest I don't really feel limited by the tools that I use (like python + NumPy) so I can't use that excuse. I have no particular desire to work in the finance industry, which seems to be the main port of call for K users at least. Plus I should really learn C# as a next language as it's the primary language where I work. So practically speaking, J almost definitely shouldn't be the next language I learn. I'm reasonably familiar with MATLAB so using an array-based programming language wouldn't constitute a tremendous paradigm shift. Any advice from those familiar with these languages would be much appreciated.

  • Implementing eval and load functions inside a scripting engine with Flex and Bison.

    - by Simone Margaritelli
    Hy guys, i'm developing a scripting engine with flex and bison and now i'm implementing the eval and load functions for this language. Just to give you an example, the syntax is like : import std.*; load( "some_script.hy" ); eval( "foo = 123;" ); println( foo ); So, in my lexer i've implemented the function : void hyb_parse_string( const char *str ){ extern int yyparse(void); YY_BUFFER_STATE prev, next; /* * Save current buffer. */ prev = YY_CURRENT_BUFFER; /* * yy_scan_string will call yy_switch_to_buffer. */ next = yy_scan_string( str ); /* * Do actual parsing (yyparse calls yylex). */ yyparse(); /* * Restore previous buffer. */ yy_switch_to_buffer(prev); } But it does not seem to work. Well, it does but when the string (loaded from a file or directly evaluated) is finished, i get a sigsegv : Program received signal SIGSEGV, Segmentation fault. 0xb7f2b801 in yylex () at src/lexer.cpp:1658 1658 if ( YY_CURRENT_BUFFER_LVALUE->yy_buffer_status == YY_BUFFER_NEW ) As you may notice, the sigsegv is generated by the flex/bison code, not mine ... any hints, or at least any example on how to implement those kind of functions? PS: I've succesfully implemented the include directive, but i need eval and load to work not at parsing time but execution time (kind of PHP's include/require directives).

  • Best way to make a WYSIWYG in Flex?

    - by hngry4powr
    Hello, I have a client that wants a WYSIWYG form that behaves like MS word. It will have some section labels in it, with users expected to enter notes for each section, and it needs a place holder for a chart. The trick is that the user needs to know where page breaks are going to fall when printed. The customer agrees to fixed size paper with fixed sized margins. How should I approach this challenge? Thank you very much for your suggestions. Here is an example: Section 1: Explain Idea Here { As user types in this section, the space between this section and the next section expands, but I as the user can't delete the lines that say Section 1 or 2, or the place holder for the chart. However if I type a lot of text, I need to display where the page breaks are with a dashed line or something, so the user can make sure the content enters appears on the desired page. If I type a lot here for example, section 2 will get pushed onto the next page} Section 2: State why this is a Good Idea [ PLACE HOLDER FOR CHART . . . ] Section 3: Additional Remarks:

  • MapScale not being persisted properly in mxd when programmatically changed outside of ArcMap environ

    - by Vidar
    I am trying to change the scale of a map in an mxd OUTSIDE of ArcMap in a standalone Windows application. The problem is the scale is never persisted - the best code I have come up with is the following: private void UpdateMapScaleInMxd(double scale, string mxdFullPath) { IMapDocument mapDocument = new MapDocumentClass(); mapDocument.Open(mxdFullPath, ""); IPageLayout pageLayout = (IPageLayout)mapDocument.ActiveView; IGraphicsContainer graphicsContainer = (IGraphicsContainer)pageLayout; graphicsContainer.Reset(); IMapFrame mapFrame; IActiveView tmpActiveView = null; IElement element = graphicsContainer.Next(); while (element != null) { if (element is IMapFrame) { mapFrame = (IMapFrame)element; tmpActiveView = (IActiveView)mapFrame.Map; mapFrame.ExtentType = esriExtentTypeEnum.esriExtentScale; mapFrame.MapScale = scale; tmpActiveView.Refresh(); } element = graphicsContainer.Next(); } mapDocument.Save(false, false); mapDocument.Close(); } I check the mxd by opening it up in ArcMap and the map scale has changed, although the little combobox to change the scale is now greyed out - does anyone know what that means!? So now I try to export the map as a PDF in code - and the most frustrating thing is - it exports the map at the previous scale that was set - NOT the scale I just changed it to! So infuriating - if anyone can help me understand where I am going wrong that would be great.

  • Manually filling opcode cache for entire app using apc_compile_file, then switching to new release.

    - by Ben
    Does anyone have a great system, or any ideas, for doing as the title says? I want to switch production version of web app-- written in PHP and served by Apache-- from release 1234 to release 1235, but before that happens, have all files already in the opcode cache (APC). Then after the switch, remove the old cache entries for files from release 1234. As far as I can think of there are three easy ways of atomically switching from one version to the next. Have a symbolic link, for example /live, that is always the document root but is changed to point from one version to the next. Similarly, have a directory /live that is always the document root, but use mv live oldversion && mv newversion live to switch to new version. Edit apache configuration to change the document root to newversion, then restart apache. I think it is preferable not to have to do 3, but I can't think of anyway to precompile all php files AND use 1 or 2 to switch release. So can someone either convince me its okay to rely on option 3, or tell me how to work with 1 or 2, or reveal some other option I am not thinking of?

  • (outofmemoryerror: java heap space) when iterating through oracle records...

    - by rockit
    hello fellow java developers. I'm having a bit of an issue here. I have code that gets a resultset from an oracle database, prints each row to a file, then gets the next row - and continues till the end of the resultset. Only this isn't what happens. What happens is that it gets the resultset, starts iterating through the rows, printing to file as it goes, until it runs out of memory - claiming it needs more space on the java heap. The app is currently running with 2g of memory on the heap and the code breaks at about the 150000th row. I'm using jodbc6.jar and java 6 Here is an idea of what my code is doing: Connection conn = DriverManager.getConnection(url,"name","pwd"); conn.setAutoCommit(false); Statement stmt = conn.createStatement(); ResultSet rset = stmt.executeQuery(strSql); String strVar_1 = null; long lCount = 0; while(rset.next()){ lCount++; if (lCount % 100000 == 0){ System.out.println(lCount + " rows completed"); } strVar_1 = rset.getString("StringID"); /// breaks here!!!!!!!!! if (strVar_1 == null){ strVar_1 = ""; } if (!strQuery_1.equals("")){ out.write(strVar_1 + "\n"); } } out.close();

  • Help ! How do I get the total number rows from my SQL Server paging procedure ?

    - by The_AlienCoder
    Ok I have a table in my SQL Server database that stores comments. My desire is to be able to page though the records using [Back],[Next], page numbers & [Last] buttons in my data list. I figured the most efficient way was to use a stored procedure that only returns a certain number of rows within a particular range. Here is what I came up with @PageIndex INT, @PageSize INT, @postid int AS SET NOCOUNT ON begin WITH tmp AS ( SELECT comments.*, ROW_NUMBER() OVER (ORDER BY dateposted ASC) AS Row FROM comments WHERE (comments.postid = @postid)) SELECT tmp.* FROM tmp WHERE Row between (@PageIndex - 1) * @PageSize + 1 and @PageIndex*@PageSize end RETURN Now everything works fine and I have been able implement [Next] and [Back] buttons in my data list pager. Now I need the total number of all comments (not in the current page) so that I can implement my page numbers and the[Last] button on my pager. In other words I want to return the total number of rows in my first select statement i.e WITH tmp AS ( SELECT comments.*, ROW_NUMBER() OVER (ORDER BY dateposted ASC) AS Row FROM comments WHERE (comments.postid = @postid)) set @TotalRows = @@rowcount @@rowcount doesn't work and raises an error. I also cant get count.* to work either. Is there another way to get the total amount of rows or is my approach doomed.

  • How to create a "Shell IDList Array" to support drag-and-drop of virtual files from C# to Windows Ex

    - by JustABill
    I started trying to implement drag-and-drop of virtual files (from a C# 4/WPF app) with this codeplex tutorial. After spending some time trying to figure out a DV_E_FORMATETC error, I figured out I need to support the "Shell IDList Array" data format. But there seems to be next to zero documentation on what this format actually does. After some searching, I found this page on advanced data transfer which said that a Shell IDList Array was a pointer to a CIDA structure. This CIDA structure then contains the number of PIDLs, and a list of offsets to them. So what the hell is a PIDL? After some more searching, this page sort of implies it's a pointer to an ITEMIDLIST, which itself contains a single member that is a list of SHITEMIDs. My next idea was to try dragging a file from another application with virtual files. I just got a MemoryStream back for this format. At least I know what class to provide for the thing, but that doesn't help at all for explaining what to put in it. So now that that's explained, I still have no idea how to create one of these things so that it's valid. There's two real questions here: What is a valid "abID" member for a SHITEMID? These virtual files only exist with my program; will the thing they are dragged to pass the "abID" back later when it executes GetData? Do they have to be system-unique? Why are there two levels of lists; a list of PIDLs and each PIDL has a list of SHITEMIDs? I'm assuming one of them is one for each file, but what's the other one for? Multiple IDs for the same file? Any help or even links that explain what I should be doing would be greatly appreciated.

  • Making a simple searchable directory of people and their skills in a day - Which technologies?

    - by gav
    Hi All, I am working with a small theatre company. Currently they have a list of people on paper with notes about their skills next to each one. I want to create a database / directory for them so that they can add, delete, update and search for people. It is a very simple and common scenario I know but the issue here is that I only have a day to build a working solution. The search has to be very simple At first I was thinking LAMP but I'd rather not have to create it all from scratch and host it myself. That lead me to Google Spreadsheet as a database, this has the advantage that they already use google docs for everything and if my front end goes tits up they can still get to the data. Presuming none of you can think of some existing software which does exactly what I want the next step is to make a front end for the database. You can create forms for Google Spreadsheets but they only let you add new entries, I can make a Google Gadget but that will only let me implement the search as the Google Visualisation API provides read only access. It's at this point I'm stuck, should I just create a Java Servlet front end for the Google Spreadsheet and use the Java API to add, search and update? I know this is a broad question but I'm just asking 'What would you do?' to implement this system with a day's development time? Gav

  • Eclipse Juno won't create Android Activity

    - by MikkoP
    I downloaded Eclipse Juno Java EE edition and installed ADT plugin. I created a new Android Application Project from Eclipse and in the wizard I created an activity called TaskariActivity. After I pressed finish, it created the project but not the activity and the wizard didn't close. I pressed cancel. No activity or anything in the src folder. I created a new activity by right clicking on src, selecting new -> other -> Android -> activity. I selected BlankActivity (as earlier when I was creating the project), selected the earlier created project in the Project combo box. I set the Activity name as TaskariActivity, layout name as activity_main and title as TaskariActivity. Next I selected navigation type and I set it to Tabs + Swipe (I thought this would make me tabs and everything I had to do would be just inserting the elements and the actions for them). I pressed next, nothing happened. Finish didn't also do anything. I pressed cancel and an activity wasn't created. So, how can I create an Android application like in the earlier version of Eclipse? It automatically created the activity and it was ready be run out of the box. Now it won't generate any files and the new activity wizard doesn't work. Help?

  • best practice to persist classes model

    - by Yaron Naveh
    My application contains a set of model classes. e.g. Person, Department... The user changes values for instances of these classes in the UI and the classes are persisted to my "project" file. Next time the user can open and edit the project. Next version of my product may change the model classes drastically. It will still need to open existing projects files (I will know how to handle missing data). How is it best to persist my model classes to the project file? The easiest way to persist classes is Data contract serialization. However it will fail on breaking changes (I expect to have such). How to handle this? use some other persistence, e.g. name-value collection or db which is more tolerance ship a "project converter" application to migrate old projects. This requires to either ship with both old and new models or to manipulate xml, which is best?

  • How to parse phpDoc style comment block with php?

    - by Reveller
    Please consider the following code with which I'm trying to parse only the first phpDoc style comment (noy using any other libraries) in a file (file contents put in $data variable for testing purposes): $data = " /** * @file A lot of info about this file * Could even continue on the next line * @author [email protected] * @version 2010-05-01 * @todo do stuff... */ /** * Comment bij functie bar() * @param Array met dingen */ function bar($baz) { echo $baz; } "; $data = trim(preg_replace('/\r?\n *\* */', ' ', $data)); preg_match_all('/@([a-z]+)\s+(.*?)\s*(?=$|@[a-z]+\s)/s', $data, $matches); $info = array_combine($matches[1], $matches[2]); print_r($info) This almose works, except for the fact that everything after @todo (including the bar() comment block and code) is considered the value of @todo: Array ( [file] => A lot of info about this file Could even continue on the next line [author] => [email protected] [version] => 2010-05-01 [todo] => do stuff... / /** Comment bij functie bar() [param] => Array met dingen / function bar() { echo ; } ) How does my code need to be altered so that only the first comment block is being parsed (in other words: parsing should stop after the first "*/" encountered?

  • I want to run two or more procedures in parallel

    - by binod gyawali
    I have list of procedures. All procedures are not dependent upon each other. So, I need to do is, to run the independent procedures in parallel. I have 4 procedures that are to be run parallel. When the procedures are run successfully, now I need to go to the next task. These procedures create about 10 tables. Next task is to execute the set of procedures. I have made one table, where I describe the dependency of these procedures to the tables created above. After any one of the above procedures is completed, I should come to this set of procedures, and find out those procedures whose dependency tables are already created. If any procedure whose dependent tables creation is completed, I need to execute this procedure. Running 4 procedures parallel is done by dts. But, difficulty for me is to transfer the task from the above 4 procedures to the below set of procedures. Please help me to complete my task. Thanks in advance

  • Read specific line from text file, according to Checked Listbox selection number.

    - by Manolis
    Heya, i want to create an application which will read a specific line from a text file and show it in a textbox. The line will be chosen according to the number of the listbox selection i will make. Here's the code: Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim i As Integer For i = 0 To Me.CheckedListBox1.CheckedIndices.Count - 1 Me.CheckedListBox1.SetItemChecked(Me.CheckedListBox1.CheckedIndices(0),False) Next i End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click If CheckedListBox1.CheckedItems.Count <> 0 Then Dim reader As New System.IO.StreamReader(CurDir() & "\" & "READ.txt") Dim x As Integer Dim s As String = "" For x = 0 To CheckedListBox1.CheckedItems.Count - 1 s = s & "Answer " & (x + 1).ToString & ") " & CheckedListBox1.CheckedItems(x).ToString & ControlChars.CrLf & reader.ReadLine() & ControlChars.CrLf & ControlChars.CrLf Next x Answer.Text = (s) Else MessageBox.Show("Please select questions.", "Error", _ MessageBoxButtons.OK, _ MessageBoxIcon.Information) Return End If End Sub End Class So lets say i 'check' the first, second, and fifth items from the checked listbox, i want it to read from the text file the first, second, and fifth lines of text and show them in the textbox. The current code just reads line 1, 2, 3 (...) in order, no matter what item i have 'checked'. Thanks in advance!
