  • Replacing a colour/colours in a movieclip with different colours?

    - by Oli
    I am trying to take a movieclip of a character and change the colour of their clothes. The character is comprised of vectors. So far I have semi-sucessfully used this method: stop the movieclip take the bitmap data from the current frame use threshold to replace the colour store the resulting bitmap data in an array add an onenterframe function - clear the current frame and add the bitmap data from the processed data in the array So - this works pretty well. Each frame is only processed once at the beginning and then the write to the movieclip is very quick. However! As the replacement is being performed on a bitmap there is an amount of aliasing that takes place to remove jaggies/pixelation. This produces colours that are not matched using threshold. So the main colour is replaced correctly but it is surrounded by a halo of mixed colours :( I am sure there should be a better way to do this. Any ideas or answers would be greatly apreciated - Thanks.

  • Logging into oracle db as a global user

    - by kineas
    We are trying to shape up an old, 2 tier, Delphi based application. It originally uses database authentication, we'd like to transform the db user accounts to global users, so an OID server could perform the authentication instead of the database. The Delphi program can no longer log into the database if the account is a global user. I'm trying to understand the login protocol, so far without results. Similar thing happens with SQLDeveloper, I can't connect as a global user. SQLPlus however works with both kinds of users. We checked the information flow with Wireshark. When the dbserver asks back for a password, the SQLPlus sends it, while the SQLDeveloper doesn't send a password when attempting to connect as a global user. The client sends the application name too in the login request. Is it possible that we have to store the client app name in the LDAP itself?

  • Python urllib3 and how to handle cookie support?

    - by bigredbob
    So I'm looking into urllib3 because it has connection pooling and is thread safe (so performance is better, especially for crawling), but the documentation is... minimal to say the least. urllib2 has build_opener so something like: #!/usr/bin/python import cookielib, urllib2 cj = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) r = opener.open("http://example.com/") But urllib3 has no build_opener method, so the only way I have figured out so far is to manually put it in the header: #!/usr/bin/python import urllib3 http_pool = urllib3.connection_from_url("http://example.com") myheaders = {'Cookie':'some cookie data'} r = http_pool.get_url("http://example.org/", headers=myheaders) But I am hoping there is a better way and that one of you can tell me what it is. Also can someone tag this with "urllib3" please.

  • How can I make a Twitter style alert stick to the top of the window?

    - by Robert Robb
    There is an excellent code example on how to make nice jQuery Twitter style alerts here: http://blog.codecrate.com/2009/10/twitter-style-alerts-in-rails.html $(function () { var alert = $('.alert'); if (alert.length > 0) { alert.show().animate({height: alert.outerHeight()}, 200); window.setTimeout(function() { alert.slideUp(); }, 3000); } }); However, one thing that the code doesn't include is functions to stick the alert div to the top of the window, no matter how far down the page the user has scrolled. I have found a few examples but nothing seems to play nice with this existing code. Any ideas?

  • Sending email from Drupal contact form, but GMail marks it as "Forged"

    - by James Shields
    Hi, My Drupal site sends email to a GMail account, but the emails sent all go into the Spam folder, and GMail puts up a bar with the message "This message was likely forged and did not originate from your account." Although I can create a filter to prevent them going to Spam, I want to start sending newsletters, and I suspect they'll have the same problem. I suspect the problem is with the way I've set up either PHP or Drupal to send mail. As far as I know it's just using the sendmail function. I've set the from address to "info@..." where ... is the site domain. Any tips on how I can make set up my outgoing mail so it won't be refused by GMail (and presumably other major mail providers)? Thanks, James

  • Opinions about the current and future state of Dabo

    - by ChrisC
    Has anyone used Dabo lately? How does it rate vs Boa Constructor, etc? I'm writing a new Python database app and Dabo looks promising, but what's the real-world scoop on it? Is it used by many developers? It's not talked about very much here on SO, or anywhere, as far as I can tell. I'm just a little concerned that the support community might be too small, or the possibility that writers might decide to throw in the towel. What are your opinions of Dabo?

  • How can I specify my own Rhino context in Java?

    - by Dan Howard
    I'm trying to ensure that my Rhino scripts (running under Java 6) are strict so that if a script developer misspells an expression I want an exception to be thrown. Currently what happens is the expression simply evaluates to "undefined". Now according to Mozilla org https://developer.mozilla.org/en/New_in_Rhino_1.6R6 there are features to enable strict checking in the context. I cannot find a working example of this. What I did so far was write a class to extend ContextFactory and then override the hasFeature method. public class ScriptContextFactory extends ContextFactory { protected boolean hasFeature(Context context, int featureIndex) { switch (featureIndex) { case Context.FEATURE_STRICT_EVAL: return true; case Context.FEATURE_STRICT_VARS: return true; } return super.hasFeature(context, featureIndex); } } Then in the Main I set mine to the default. ContextFactory.initGlobal(new ScriptContextFactory()); and I get an illegal state exception. :( Any ideas or samples on how this works? TIA

  • Most flexible minimizer/compressor for ASP.NET MVC 2?

    - by AlexanderN
    From your experience, what's the most flexible minimizer/compressor (JS+CSS) for ASP.NET MVC you've dealt with? So far mbcompress doesn't seem to be too MVC friendly weboptimizer.codeplex.com lacks documentation clientdependency.codeplex.com is still in beta compress2 seems like a good candidate, but haven't tried it yet mvcscriptmanager only combines and compresses javascript but not CSS By flexible I mean Choose what should be compressed, minified, and combined Add exceptions. E.g. if debug don't compress XYZ.JS or don't minify ABC.CSS Caching In the end, it should help offer the best YSLOW score. If you know of any other assemblies out there, please list them also.

  • Java NullPointerException when traversing a non-null recordset

    - by Tim
    Hello again - I am running a query on Sybase ASE that produces a ResultSet that I then traverse and write the contents out to a file. Sometimes, this will throw a NullPointerException, stating that the ResultSet is null. However, it will do this after printing out one or two records. Other times, with the same exact input, I will receive no errors. I have been unable to consistently produce this error. The error message is pointing to a line: output.print(rs.getString(1)); It appears to happen when the query takes a little longer to run, for some reason. The recordset returns thus far have been very small (4 to 7 records). Sometimes I'll have to run the app 3 or 4 times, then the errors will just stop, as though the query was getting "warmed up". I've run the query manually and there doesn't appear to be any performance problems. Thanks again!

  • Backup AWS Dynamodb to S3

    - by Ali
    It has been suggested on Amazon docs http://aws.amazon.com/dynamodb/ among other places, that you can backup your dynamodb tables using Elastic Map Reduce, I have a general understanding of how this could work but I couldn't find any guides or tutorials on this, So my question is how can I automate dynamodb backups (using EMR)? So far, I think I need to create a "streaming" job with a map function that reads the data from dynamodb and a reduce that writes it to S3 and I believe these could be written in Python (or java or a few other languages). Any comments, clarifications, code samples, corrections are appreciated.

  • What is the best way to migrate documents into Sharepoint (MOSS) 2007?

    - by Jeramie Mercker
    I'm working with a customer that needs to migrate documents from their current document management system (not Sharepoint) into Sharepoint MOSS 2007 retaining document history and metadata. I've written a proof of concept using the Sharepoint web services and that looks promising, but the snag so far seems to be programmatically setting the created date/time and user. The webservices allow the fields to be set but implicitly override them to be the currently logged in user + date/time. For obvious reasons, I need to be able to keep the original created date/time and user on migration. Does anyone know the best way to approach this problem?

  • Reading an Excel file in PHP

    - by Dinah
    I'm trying to read an Excel file (Office 2003). There is an Excel file that needs to be uploaded and its contents parsed. Via Google, I can only find answers to these related (and insufficient topics): generating Excel files, reading Excel XML files, reading Excel CSV files, or incomplete abandoned projects. I own Office 2003 so if I need any files from there, they are available. It's installed on my box but isn't and can't be installed on my shared host. Edit: so far all answers point to PHP-ExcelReader and/or this additional article about how to use it.

  • Delphi for PHP - location of source

    - by Holgerwa
    I just installed Delphi for PHP to get an idea on how it works and have created a simple app with a button that puts a text into a listbox when it is clicked. The app works if I copy all required files to my webserver and run it from there. It also works if I save the project in the standard path: "c:\documents and settings\username\My Documents\Delphi for PHP Projects" But if I save the project in another directory, the ButtonClick event is not fired when the application runs from there. I've put a breakpoint in the event to see if it stops there but it doesn't. The OnShow event of the form works as usual. It really seems to be the path where the project is located to make it either work or not. As I said, I have no experience with Delphi for PHP so far, it is probably just a simple solution that I don't see...

  • Do you use Scimore SQL database ?

    - by Darian Miller
    There's a database engine that looks amazing for a free tool and that is Scimore. Have you had much experience with it? If so, how does it rate..particularly against Firebird? How resilient/self reliant is it? (Meaning how much downtime/maintenance is expected?) The scale out capabilities also look very interesting. I just downloaded it and have been playing around and so far it looks good. I had been looking for an easy to deploy single-user type embedded database (which Scimore has an option) and was toying with MS SQL Compact Edition and SQLite and remembered this database from a trial a few years ago. (Windows platform) I was about ready to settle in on SQLite but started thinking about other projects which are multi-user and wanted to stick with a single solution...which is why I started looking at Firebird as well.

  • Union on ValuesQuerySet in django

    - by Wuxab
    I've been searching for a way to take the union of querysets in django. From what I read you can use query1 | query2 to take the union... This doesn't seem to work when using values() though. I'd skip using values until after taking the union but I need to use annotate to take the sum of a field and filter on it and since there's no way to do "group by" I have to use values(). The other suggestions I read were to use Q objects but I can't think of a way that would work. Do I pretty much need to just use straight SQL or is there a django way of doing this? What I want is: q1 = mymodel.objects.filter(date__lt = '2010-06-11').values('field1','field2').annotate(volsum=Sum('volume')).exclude(volsum=0) q2 = mymodel.objects.values('field1','field2').annotate(volsum=Sum('volume')).exclude(volsum=0) query = q1|q2 But this doesn't work and as far as I know I need the "values" part because there's no other way for Sum to know how to act since it's a 15 column table.

  • Making a textfile into a list in matlab?

    - by Ben Fossen
    I have a textfile and would like to import it onto Matlab and make it a list Person1 name = steven grade = 11 age= 17 Person2 name = mike grade = 9 age= 15 Person3 name = taylor grade = 11 age= 17 There are a few hundred entries like these above. Each are seperated by a blank line I was thinking I could scan the text and make the information between each blank line into an item in the list. I also would like to be able to look up each person by name once I have a list like the one below. I want something like x = [Person1 Person2 Person3 name = steven name = mike name = taylor grade = 11 grade = 9 grade = 11 age = 17 age = 15 age = 17] This seems very straight forward but I have been having trouble with this so far, I may be overlooking something. anyone have any ideas or advice?

  • What makes you want to learn Common Lisp? What do you want from it?

    - by JasonFruit
    I'm working on a toolkit (sort of a live-CD Lisp-in-a-Box) for people new to Common Lisp, and I want to make sure it is broadly satisfying. What is attractive to you about Lisp? What do/did/would you need to get you started and keep you interested? What I have so far: SBCL 10.22, Emacs 22.3, SLIME, and LTK bundled together and configured on a Linux live-CD that boots entirely to RAM. I've now released the result of this; it is available at the Thnake website.

  • Qt - invalid conversion to child class

    - by David Davidson
    I'm drawing polygons using the Graphics View framework. I added a polygon to the scene with this: QGraphicsPolygonItem *poly = scene->addPolygon(QPolygonF(vector_of_QPointF)); poly->setPos(some_point); But I need to implement some custom behaviour like selection, mouse over indicator, and other similar stuff on the graphics item. So I declared a class that inherits QGraphicsPolygonItem: #include <QGraphicsPolygonItem> class GridHex : public QGraphicsPolygonItem { public: GridHex(QGraphicsItem* parent = 0); }; GridHex::GridHex(QGraphicsItem* parent) : QGraphicsPolygonItem(parent) { } Not doing much with that class so far, as you can see. But shouldn't replacing QGraphicsPolygonItem with my GridHex class? This is throwing a " invalid conversion from 'QGraphicsPolygonItem*' to 'GridHex*' " error: GridHex* poly = scene->addPolygon(QPolygonF(vector_of_QPointF)); What am I doing wrong?

  • Search resetting selection in tableview

    - by Jay
    I've got an NSTableView bound to an NSArrayController via content and selection indexes. All great so far - content displayed, etc. Now an NSSearchField is bound to the array controller via filterPredicate and the property of the array content instances that's to be searched. Searching/filtering the table view works great; table view showing only matching entries. However, searching resets the selection on the NSTableView if the existing selection isn't in the search results. Worse, not only during the search but after ending the search there's no selection on the table view. The NSArrayController is set up to Avoid Empty Selection. Any hints on how to properly configure bindings in this scenario to really prevent an empty selection much appreciated!

  • How to communicate/share a session between pages over HTTP and HTTPS

    - by spirytus
    What is common practice for coding web applications where part of the site has to be secured (e.g. checkout section) and part not necessarily, let's say homepage? As far as I know sharing sessions in between HTTP and HTTPS parts of the site is not easily possible (or is it?). What would be common approach if I wanted to display on HTTP page like homepage, shopping cart data (items) that users ordered on HTTPS pages? How those two parts of the site would communicate if necessary? Also isn't it security flaw in popular shopping carts as it seems that many of these have only checkout pages secured (SSL) and the rest not? I'm using PHP if it makes any difference.

  • Why implement DB connection pointer object as a reference counting pointer? (C++)

    - by DVK
    At our company one of the core C++ classes (Database connection pointer) is implemented as a reference counting pointer. To be clear, the objects are NOT DB connections themselves, but pointers to a DB connection object. The library is very old, and nobody who designed is around anymore. So far, nether I, nor any C++ experts in the company that I asked have come up with a good reason for why this particular design was chosen. Any ideas? It is introducing some problems (partially due to awful reference pointer implementation used), and I'm trying to understand if this design actually has some deep underlying reasons? The usage pattern these days seems to be that the DB connection pointer object is returned by a DB connection manager class, and it's somewhat unclear whether DB connection pointers were designed to be able to be used independently of DB connection manager.

  • Windows Phone Mango: Making a drawing app with various brushes option

    - by Md. Abdul Munim
    I am trying to make a drawing app. The purpose is simple. Let the user draw something on a canvas with various brush options like square brush,far brush,pencil brush and many more like any other drawing app available in android market. At present I can let the user draw smooth curves using following code: currentPoint = e.GetPosition(this.canvas); Line line = new Line() { X1 = currentPoint.X, Y1 = currentPoint.Y, X2 = oldPoint.X, Y2 = oldPoint.Y }; line.Stroke = new SolidColorBrush(Colors.Purple); line.StrokeThickness = 2; this.drawnImage.Add(line); this.canvas.Children.Add(line); oldPoint = currentPoint; Now I want some custom brush options and let the user draw using that.How can I achieve that? Thanks in advance.

  • How to use a proprety/value table in MySQL

    - by David
    I inherited a mysql database that has a table with columns like this: object_id, property, value It holds data like this: 1,first_name,Jane 1,last_name,Doe 1,age,10 1,color,red 2,first_name,Mike 2,last_name,Smith 2,age,20 2,color,blue 3,first_name,John 3,last_name,Doe 3,age,20 3,color,red ... Basically what I want to do is treat this table as a regular table. How would I get the id numbers (or all properties) of a person who is age 20 sorted by last and than first name? So far I have: SELECT object_id FROM table WHERE property = 'age' AND value = '20' union SELECT object_id FROM table WHERE property = 'color' AND value = 'red' But I'm not sure how to go about ordering the data. Thanks
