  • Return highest number found in an array of strings

    - by Mdd
    I have an array of objects. The objects have a property called level that is a string which contains a number and is in consistent format. I am trying to find the highest number and return just that one but I seem to be blocked as far as how to proceed from my current code. Here is a fiddle to my current code: http://jsfiddle.net/6sXYR/ Here is my JavaScript: var myArray = [ { color: 'blue', level: 'L1' }, { color: 'red', level: 'L1' }, { color: 'green', level: 'L2' }, { color: 'yellow', level: 'L2' }, { color: 'purple', level: 'L3' } ]; for (var i = 0; i < myArray.length; i++) { console.log( myArray[i].level.substring(1,2) ); }; The result I am trying to get is to return just the number '3' from the example above. The highest number may not always be in the last object in the array, but it will always be in the format of L#.

  • make reference to an empty query in flex

    - by Adam
    a bit of a dumb questions I'm sure I'm trying to allow user to set an item to be default. I've got a function that run a query to first find the current default item. Then runs a second query that unsets the current default item. Then a third query runs to set the new user selected item to be the default. This seem to work fine when a default item has been perviously selected, but when I try to set the default item initially I get the good old "Cannot access a property or method of a null object reference." error. This is because the first query that runs returns no items I'm sure. So I need to write an if statement that if the first query returns nothing to skip the second and go right to the third. The only problem is I can't make a reference to a null object. So how do I go about writing this statement. Thanks

  • 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.

  • Twisted chainDeferred not working as expected

    - by Martin Gergov
    I have a problem figuring out a somewhat simple twisted python code. From what I have red in the docs, the code here should work without Unhandled Error. I get this: HELLO! HANDLED! HANDLED 2! Unhandled error in Deferred: Unhandled Error Traceback (most recent call last): File "package_tester.py", line 31, in <module> a().callback(2) File "/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.py", line 368, in callback self._startRunCallbacks(result) File "/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.py", line 464, in _startRunCallbacks self._runCallbacks() --- <exception caught here> --- File "/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.py", line 551, in _runCallbacks current.result = callback(current.result, *args, **kw) File "package_tester.py", line 5, in c raise Exception() exceptions.Exception: Isn't the failure from the chained deferred passed to end() errback ?

  • How to find loginname, database username, or roles of sqlserver domain user who doesn't have their own login?

    - by Adam Butler
    I have created a login and database user called "MYDOMAIN\Domain Users". I need to find what roles a logged on domain user has but all the calls to get the current user return the domain username eg. "MYDOMAIN\username" not the database username eg. "MYDOMAIN\Domain Users". For example, this query returns "MYDOMAIN\username" select original_login(),suser_name(), suser_sname(), system_user, session_user, current_user, user_name() And this query returns 0 select USER_ID() I want the username to query database_role_members is there any fuction that will return it or any other way I can get the current users roles?

  • Handling Incoming Data from Multiple Sockets in Python

    - by user859434
    Background: I have a current implementation that receives data from about 120 different socket connections in python. In my current implementation, I handle each of these separate socket connections with a dedicated thread for each. Each of these threads parse the data and eventually store it within a shared locked dictionary. These sockets DO NOT have uniform data rates, some sockets get more data than others. Question: Is this the best way to handle incoming data in python, or does python have a better way on handling multiple sockets per thread?

  • Override Java System.currentTimeMillis

    - by Mike Clark
    Is there a way, either in code or with JVM arguments, to override the current time, as presented via System.currentTimeMillis, other than manually changing the system clock on the host machine? A little background: We have a system that runs a number of accounting jobs that revolve much of their logic around the current date (ie 1st of the month, 1st of the year, etc) Unfortunately, a lot of the legacy code calls functions such as new Date() or Calendar.getInstance(), both of which eventually call down to System.currentTimeMillis. For testing purposes, right now, we are stuck with manually updating the system clock to manipulate what time and date the code thinks that the test is being run. So my question is: Is there a way to override what is returned by System.currentTimeMillis? For example, to tell the JVM to automatically add or subtract some offset before returning from that method? Thanks in advance!

  • innodb lock wait timeout

    - by shantanuo
    As per the documentation link given below: When a lock wait timeout occurs, the current statement is not executed. The current transaction is not rolled back. (Until MySQL 5.0.13 InnoDB rolled back the entire transaction if a lock wait timeout happened. You can restore this behavior by starting the server with the --innodb_rollback_on_timeout option, available as of MySQL 5.0.32. http://dev.mysql.com/doc/refman/5.0/en/innodb-parameters.html#sysvar_innodb_lock_wait_timeout Does it mean that when a lock wait timeout occurs, it compromises the transactional integrity? "roollback on timeout" was the default behaviour till 5.0.13 and I guess that was the correct way to handle such situations. Does anyone think that this should be the default behaviour and the user should not be asked to add a parameter for a functionality that is taken for granted?

  • Moving a unit precisely along a path in x,y coordinates

    - by Adam Eberbach
    I am playing around with a strategy game where squads move around a map. Each turn a certain amount of movement is allocated to a squad and if the squad has a destination the points are applied each turn until the destination is reached. Actual distance is used so if a squad moves one position in the x or y direction it uses one point, but moving diagonally takes ~1.4 points. The squad maintains actual position as float which is then rounded to allow drawing the position on the map. The path is described by touching the squad and dragging to the end position then lifting the pen or finger. (I'm doing this on an iPhone now but Android/Qt/Windows Mobile would work the same) As the pointer moves x, y points are recorded so that the squad gains a list of intermediate destinations on the way to the final destination. I'm finding that the destinations are not evenly spaced but can be further apart depending on the speed of the pointer movement. Following the path is important because obstacles or terrain matter in this game. I'm not trying to remake Flight Control but that's a similar mechanic. Here's what I've been doing, but it just seems too complicated (pseudocode): getDestination() { - self.nextDestination = remove_from_array(destinations) - self.gradient = delta y to destination / delta x to destination - self.angle = atan(self.gradient) - self.cosAngle = cos(self.angle) - self.sinAngle = sin(self.angle) } move() { - get movement allocation for this turn - if self.nextDestination not valid - - getNextDestination() - while(nextDestination valid) && (movement allocation remains) { - - find xStep and yStep using movement allocation and sinAngle/cosAngle calculated for current self.nextDestination - - if current position + xStep crosses the destination - - - find x movement remaining after self.nextDestination reached - - - calculate remaining direct path movement allocation (xStep remaining / cosAngle) - - - make self.position equal to self.nextDestination - - else - - - apply xStep and yStep to current position - } - round squad's float coordinates to integer screen coordinates - draw squad image on map } That's simplified of course, stuff like sign needs to be tweaked to ensure movement is in the right direction. If trig is the best way to do it then lookup tables can be used or maybe it doesn't matter on modern devices like it used to. Suggestions for a better way to do it? an update - iPhone has zero issues with trig and tracking tens of positions and tracks implemented as described above and it draws in floats anyway. The Bresenham method is more efficient, trig is more precise. If I was to use integer Bresenham I would want to multiply by ten or so to maintain a little more positional accuracy to benefit collisions/terrain detection.

  • Why doesnt doesnt HTML input of type file not work with Ajax update panel

    - by Sean P
    I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why??? This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.) Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim uploads As HttpFileCollection uploads = HttpContext.Current.Request.Files For i As Integer = 0 To (uploads.Count - 1) If (uploads(i).ContentLength > 0) Then Dim c As String = System.IO.Path.GetFileName(uploads(i).FileName) Try uploads(i).SaveAs("C:\UploadedUserFiles\" + c) Span1.InnerHtml = "File Uploaded Sucessfully." Catch Exp As Exception Span1.InnerHtml = "Some Error occured." End Try End If Next i End Sub This example comes from the ASP.Net website...but my application is very similar.

  • Using install_name_tool what's going wrong?

    - by 0x80
    I'm trying to change the install path of a dylib after it has been build. I use "otool -L" to check what the current path is. And then I do: $ install_name_tool -change /my/current/path/libmine.dylib /my/new/path/libmine.dylib libmine.dylib I don't get an error, but nothing changes. If I check the path again the old one is still there. Also the new path is a lot shorter then the old one, so no problem there, and I think the lib is even compiled with extra flag for more filepath space. Any ideas?

  • Create two semi-transparent images that when stacked produce the target image

    - by posfan12
    Due to CSS limitations I am forced to stack to semi-transparent images on my website. I won't go into detail regarding the CSS since if I can get this question answered the problem is moot. Anyway, I would like to modify image A in the GIMP such that it will look like it did originally after being stacked on top of image B. Both image A and image B have their opacities set to 50%. Image B is a solid color throughout, whereas image A has some minor details such as a gradient. Here's what it looks like before image B is applied on top (and what it should look like in the end): [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_target_image.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_target_image.png[/IMG][/URL] Here's what it looks like after image B has been applied on top: [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_undesired_result.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_undesired_result.png[/IMG][/URL] Thanks!

  • XNA .FBX Vertex Color Missing

    - by Alex
    When I vertex paint and export my models from Blender (or Maya) for use in my XNA 4.0 project, I somehow lose the vertex color channel for the model. I use no custom model object or content pipelines and my own shader throws me the error: The current vertex declaration does not include all the elements required by the current vertex shader. Color0 is missing. I tryed to reopen the model in other modeling tools and the vertex colors are there. What could cause the vertex color channel to not get loaded in XNA 4.0? Here's a temporary link to the FBX file(server refuses to send a fbx, so rename the .jpg file to .fbx after downloading) http://resources.gamestack.org/BananaBush.jpg

  • determine if a restaurant is open now (like yelp does) using database, php, js

    - by vee
    i was wondering if anyone knows how yelp determines what restaurants are "open now"? i'm developing a similar application using html/javascript/php. i was going to have a column in my database for each day, with comma separated hours written in "2243" format (10:43 pm). so for example if a restaurant is open for lunch and dinner it might be "1100,1400,1700,2200". then i'd check (using js) if the current time falls in one of the ranges for the current day. i'd also like to be able to determine if a restaurant is "open tonight", "open late", etc. for those i guess i'd check whether the open range overlaps with certain ranges. is there a better way to do this? particularly, how to store the hours in the database and then determine if they overlap with a given set of hours. thanks.

  • Streaming content from (sharepoint) web part

    - by Mikko Rantanen
    How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end. This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

  • Drupal - Selected Node Highlighting in Views

    - by fighella
    Drupal Question: Does anyone have a method of using Views and highlighting a selected/current node. So for example: I have a list of articles under a heading: 2009 Articles Dog Training Cat Cleaning Snake Wrangling The 3 articles are made from the view (ie: latest articles from 2009)... as the user makes new articles, they are automatically added into this view by title. I now need to find a way, that if a user clicks on say CAT CLEANING.... and the cat cleaning article appears, the CAT CLEANING in the view becomes bold (or some CSS indication it's the current article.) I know this is pretty easy with MENU's, But I don't want to force a user to add new articles into a menu. Thanks alot, JD

  • Java 2D clip area to shape

    - by user2923880
    I'm quite new to graphics in java and I'm trying to create a shape that clips to the bottom of another shape. Here is an example of what I'm trying to achieve: Where the white line at the base of the shape is the sort of clipped within the round edges. The current way I am doing this is like so: g2.setColor(gray); Shape shape = getShape(); //round rectangle g2.fill(shape); Rectangle rect = new Rectangle(shape.getBounds().x, shape.getBounds().y, width, height - 3); Area area = new Area(shape); area.subtract(new Area(rect)); g2.setColor(white); g2.fill(area); I'm still experimenting with the clip methods but I can't seem to get it right. Is this current method ok (performance wise, since the component repaints quite often) or is there a more efficient way? Thanks in advance.

  • JSF - Session Bean restart on logout and login

    - by Ben
    Hi, I have a web application with a backing bean which has the context of the current logged in user. It is implemented on JSF. When the user logs out he is forwarded to a login screen (in another JSP page). I would like the current session to be erased when that happens and a new one to be created the next time the user logs in and enters the application. My question is - how do you delete a session? (I guess the new session will be created automatically the next time the user enters the link) This is kinda newb i guess, but I couldn't find a solution for this. Thanks for the Help!

  • MediaElement seems to disable lock screen when playing a video

    - by CrossProduct
    I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

  • Make Sphinx generate me rst for class documentation from pydoc

    - by Michal Cihar
    I'm currently in process of migrating existing (non complete) documentation to Sphinx. The final goal is to have all documentation in Sphinx. The problem I'm facing right now is that I have some documentation using Python docstrings (well the module is actually written in C, but it probably does not matter) and I would like to generate class documentation in form usable for Sphinx from these docstrings. I know there is sphinx.ext.autodoc, but it automatically puts current docstrings to the document. I rather want to generate source (rst) file based on current docstrings, which I could edit and improve manually. So is there some way to turn existing docstrings into rst form which Sphinx consumes?

  • Custom script in .screenrc

    Hi. I made a script that spawns a remote shell or runs a local shell whether it's on the current machine or not: #!/bin/bash # By: benoror <[email protected]> # # spawns a remote shell or runs a local shell whether it's on the current machine or not # $1 = hostname if [ "$(hostname)" == "$1" ]; then bash else ssh "$1.local" fi For example, if I'm on server1: ./spawnshell.sh server1 -> runs bash ./spawnshell.sh server2 -> ssh to server2.local I want that script to run automatically in separate tabs in GNU Screen, but I can't make it run, my .screenrc: ... screen -t "@server1" 1 exec /home/benoror/scripts/spawnshell.sh server1 screen -t "@server2" 2 exec /home/benoror/scripts/spawnshell.sh server2 ... But it doesn't works, I've tried without 'exec', with -X option and a lot more. Any ideas ?

  • How to get a reference to IDuplexChannel, IDuplexSessionChannel or IOutputChannel in Wcf

    - by wizlb
    I have a duplex Wcf service and I'd like to get a reference to IDuplexChannel, IDuplexSessionChannel or IOutputChannel so that I can use the non-blocking BeginSend method. On my server, inside of the handler for the initiating method I have the following (I have tried every interface that I listed in place of IOutputChannel. None of them seem to exist.) _clientCb = OperationContext.Current.GetCallbackChannel<IDxClientCb>(); _channel = OperationContext.Current.Channel; _duplexChannel = _channel as IOutputChannel; Debug.Print("Service IOutputChannel null: {0}", _duplexChannel == null); Similarly, in the client I have tried to cast the return value of DuplexChannelFactory.CreateChannel() to any of these interfaces and I always get back a null. How do I get a reference to one of these?
