  • openGL ES retina support

    - by Bryan
    I'm trying to get the avTouch sample code app to run on the retina display. Has anyone done this? In the CALevelMeter class, I've tried the following: - (id)initWithCoder:(NSCoder *)coder { if (self = [super initWithCoder:coder]) { CGFloat f = self.contentScaleFactor; if ([self respondsToSelector:@selector(contentScaleFactor)]) { self.contentScaleFactor = [[UIScreen mainScreen] scale]; } f = self.contentScaleFactor; _showsPeaks = YES; _channelNumbers = [[NSArray alloc] initWithObjects:[NSNumber numberWithInt:0], nil]; _vertical = NO; _useGL = YES; _meterTable = new MeterTable(kMinDBvalue); [self layoutSubLevelMeters]; [self registerForBackgroundNotifications]; } return self; } and it sets the contentScaleFactor to "2". Great, that was expected. But then in the layoutSubviews, CALevelMeter frame is still 1/2 of what it should be. Any ideas?

  • With ASP .NET, how do I display a side submenu depending on what user picked from the main menu?

    - by Ole Media
    Hello, I come from PHP side, but I'm in need to develop a site using ASP .NET So far I manage to create a master page. Now I'm dealing with menus and submenus What I'm trying to do is, if the user picks "About Us" from the main menu, under the about us page I want to display a submenu with the options "who we are, what we do, contact us" If the user picks "Our Products" from the main menu, then under the products page I want to display a submenu with the options "product 1, product 2, product 3" Is this possible with only one master page? I read something about menu control but not sure that is what I need. So far I found how to display a sitemap, but not specific sections of a sitemap, if this is the way to do things. Any links, sample code, point of reference will be appreciated. Thanks

  • Macro to copy data from one sheet to another based on the current date

    - by SgtSnafu
    Does anyone have a macro that copy data from one sheet to another based on the current date? I am working with a single workbook of three sheets. Sheet one will hold the manual input of daily production figures for multiple plants, sheet two is to hold ongoing daily data, keyed on sheet one. The macro will be associated with a button, so that once clicked it would search for every row that has a date of today, and copy that row to the next available blank row on sheet two. Sample Data... Plant 1 Input Date - $ Produced - Labor Hour 3-29-10 - 4538 - 8 3-30-10 - 7862 - 12 3-31-10 4-1-10 4-2-10 Plant 2 Input Date - $ Produced - Labor Hour 3-29-10 - 4545 - 9 3-30-10 - 7645 - 12 3-31-10 4-1-10 4-2-10

  • Save UIView's representation to file.

    - by fish potato
    What is the easiest way to save UIView's representation to file? My solution is, UIGraphicsBeginImageContext(someView.frame.size); [someView drawRect:someView.frame]; UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); NSString* pathToCreate = @"sample.png"; NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)]; [imageData writeToFile:pathToCreate atomically:YES]; but it seems tricky, and I think there must be more efficient way to do this.

  • Pass Value between MDI Child in WinForm using C#

    - by abhilashca
    I have an MDI Parent, containing a MenuStrip. When I click on one of the Menu, two Child Forms are displayed simultaneoulsy. I have a TextBox and a Send Button on one of my ChildForm. When I type-in something in that TextBox and Click the Send Button, I need to show that value in the TextBox of my Second Child Form. What I had done is, I wrote a Public Function in the Second Child Form and tried to invoke it by creating an object of Second Form, on the Send Button click event. When I put break points, in that Public Function, I find that the control is flowing through that Public function on cliking the Send button. But the passed value is not displayed. And, I know that is not the standard way to do that. Any sample script for help? Thanks.

  • Modularity Java: top level vs. nested classes

    - by an00b
    The Java tutorials that I read, like to use nested classes to demonstrate a concept, a feature or use. This led me to initially implement a sample project I created just like that: Lots of nested classes in the main activity class. It works, but now I got a monstrous monolithic .java file. I find it somewhat inconvenient and I now intend to break to multiple .java files/classes. It occurred to me, however, that sometimes there may be reasons not to take classes out of their enclosing class. If so, what are good reasons to keep a module large, considering modularity and ease of maintenance?

  • jQuery Validate - Require at least one from group, plus additional items.

    - by Kevin Pullin
    I'm attempting to use 'jQuery Validate' on a form that requires an email address plus either all items of a shipping address completed or none at all. Using the sample provided by the solution to this question: jQuery Validate - “Either skip these fields, or fill at least X of them”, I have been able to successfully solve the validation of the address group. The problem, however, is that the logic for validating the email address field does not work. From debugging the Validate scripts, the "re-entrant" validation code triggered by calling 'fields.data('being_validated', true).valid();' in the linked example results in a reset of all previously validated errors (i.e. the email validation error is cleared). I have modified some existing samples, the first in which removes the offending line and the second with it included. Email Validation Working Email Validation Fails Any tips or suggestions on how to properly solve this or work around the failure?

  • How do I get output into Java from a SELECT stored procedure in Oracle?

    - by Ventrue
    I'm using Java to connect to an Oracle 10 Database. I want to create a stored procedure (don't ask why) that takes no arguments and returns a lot of rows. Specifically, in Java I want to be able to get this data with something like: ResultSet rs = stmt.executeQuery("call getChildless"); where getChildless is the query: SELECT objectid FROM Object WHERE objectid NOT IN (SELECT parent FROM subparts); However, I just cannot for the life of me figure out how to get my output from the stored procedure. I've googled it and I get all this sample code that Oracle won't compile, presumably it's for a previous version. Refcursors seem to come up a lot, but I'm not sure if that's what I actually want, to use it with a ResultSet.

  • My Lucene queries only ever find one hit

    - by Bob
    I'm getting started with Lucene.Net (stuck on version 2.3.1). I add sample documents with this: Dim indexWriter = New IndexWriter(indexDir, New Standard.StandardAnalyzer(), True) Dim doc = Document() doc.Add(New Field("Title", "foo", Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) doc.Add(New Field("Date", DateTime.UtcNow.ToString, Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) indexWriter.AddDocument(doc) indexWriter.Close() I search for documents matching "foo" with this: Dim searcher = New IndexSearcher(indexDir) Dim parser = New QueryParser("Title", New StandardAnalyzer()) Dim Query = parser.Parse("foo") Dim hits = searcher.Search(Query) Console.WriteLine("Number of hits = " + hits.Length.ToString) No matter how many times I run this, I only ever get one result. Any ideas?

  • Rails: Accessing previous loop in Populator (rake db:populate)

    - by sscirrus
    I am populating my Rails database using populator, and I have a case where I would like to build a series of records where fields start_date and end_date follow seamlessly from each other (from today back into the past). Here is a sample of what I'm doing: Chain.populate 1 do |ch| ch.date_end = DateTime.now ch.date_start = DateTime.civil(DateTime.now.year-rand(40)-1, rand(12)+1, rand(31)+1) end Chain.populate 0..10 do |chs| chs.date_end = Chain.find(:last).date_start chs.date_start = DateTime.civil(chs.date_end.year-rand(10)-1, rand(12)+1, rand(31)+1) end Problem? undefined method 'date_start' for nil:NilClass. I assume the problem is the first Chain record hasn't been saved, so I added: Chain.save # in between the two loops This didn't work either. How can I make this work? Thank you!

  • Cannot play a recorded sound on device.

    - by B_
    I'm using the exact code from the iPhone Application Programming Guide Multimedia Support to use AVAudioRecorder to record a file to the disk and then AVAudioPlayer to load and play that file. This is working fine in the simulator but is not working on the device. The file gets loaded (we can see the NSTimeInterval) but does not play (play returns false). After it didn't work with the sample code from the website, we tried changing to a bunch of different codecs with no success. And of course, the sound is on. Thanks a bunch.

  • Using netlink to obtain arp entries only returns stale entries

    - by Ben
    I'm currently trying to retrieve reachable neighbors from the arp table in a user space program written in c. I've looked through the source code to the "ip neigh" command (ipneigh.c) and it appears that I should use the flag NUD_REACHABLE. struct { struct nlmsghdr n; struct ndmsg r; } req; memset(&req, 0, sizeof(req)); req.n.nlmsg_len = NLMSG_LENGTH(sizeof(struct ndmsg)); req.n.nlmsg_flags = NLM_F_REQUEST | NLM_F_ROOT; req.n.nlmsg_type = RTM_GETNEIGH; req.r.ndm_state = NUD_REACHABLE; However, when I look at the data returned from the kernel, I only have stale entries. In fact, no matter what I put for req.r.ndm_state it seems to return only entries marked as stale by ip neigh. The remainder of my code is modeled after this example: http://linux-hacks.blogspot.com/2009/01/sample-code-to-learn-netlink.html

  • oracle plsql: retrieve runtime parameter values when you call a procedure

    - by Luca Vaccaro
    I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure. (plsql Oracle 10g) E.g. look at this sample procedure: (it simply prints its own name and parameters ) CREATE OR REPLACE PROCEDURE MY_PROC(ow in varchar2, tn IN varchar2) IS BEGIN dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn ); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM); END MY_PROC; / Running procedure produces the following output: SQL> 1 BEGIN 2 IBAD_OWN.MY_PROC('first_par', 'second_par'); 3 END; 4 / proc_name: MY_PROC parameters: first_par second_par PL/SQL procedure successfully completed. I'm not satisfy because I can't copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables. Thanks in advance for the help.

  • How to store local variables in jQuery click functions?

    - by Geuis
    I'm trying to figure out how to store external variable values in the functions created during jQuery's click() event. Here's a sample of the code I'm working with now. for(var i=0; i<3; i++){ $('#tmpid'+i).click(function(){ var gid = i; alert(gid); }); } <div id="tmpid0">1al</div> <div id="tmpid1">asd</div> <div id="tmpid2">qwe</div> So what's happening is that the events are attaching properly, but the value of 'gid' is always the last incremented value of 'i'. I'm not sure how to setup the private variable in this situation.

  • iPhone CGContext: drawing two lines with two different colors

    - by phonecoddy
    I am having some troubles using the CGContext with an iPhone app. I am trying to draw several lines with different colors, but all the lines always end up having to color, which was used last. I tried several approaches I could think of, but haven't been lucky. I set up a small sample project to deal with that issue. This is my code, I use in the drawRect method. I am trying to draw a red and a blue line: - (void)drawRect:(CGRect)rect{ NSLog(@"drawrect!"); CGContextRef bluecontext = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(bluecontext, 2.0); CGContextSetStrokeColorWithColor(bluecontext, [UIColor blueColor].CGColor); CGContextMoveToPoint(bluecontext, 1, 1); CGContextAddLineToPoint(bluecontext, 100, 100); CGContextSetStrokeColorWithColor(bluecontext, [UIColor redColor].CGColor); CGContextAddLineToPoint(bluecontext, 200, 100); CGContextStrokePath(bluecontext); } thanks for your help

  • Luasql and SQLite?

    - by OverTheRainbow
    Hello I just got started looking at Lua as an easy way to access the SQLite DLL, but I ran into an error while trying to use the DB-agnostic LuaSQL module: require "luasql.sqlite" module "luasql.sqlite" print("Content-type: Text/html\n") print("Hello!") Note that I'm trying to start from the most basic setup, so only have the following files in the work directory, and sqlite.dll is actually the renamed sqlite3.dll from the LuaForge site: Directory of C:\Temp <DIR> luasql lua5.1.exe lua5.1.dll hello.lua Directory of C:\Temp\luasql sqlite.dll Am I missing some binaries that would explain the error? Thank you. Edit: I renamed the DLL to its original sqlite3.dll and updated the source to reflect this (originally renamed it because that's how it was called in a sample I found). At this point, here's what the code looks like... require "luasql.sqlite3" -- attempt to call field 'sqlite' (a nil value) env = luasql.sqlite() env:close() ... and the error message I'm getting: C:\>lua5.1.exe hello.lua lua5.1.exe: hello.lua:4: attempt to call field 'sqlite' (a nil value)

  • Deploying my flex application

    - by Vatsala
    Hi, I am doing some trial testing awith Amazon ec2 boxes, deploying flex apps running on top of restlet powered webservices. I have this problem - Everytime i deploy the app to the cloud, I'm having to hardcode the IP address of the server into the ActionScript/MXML files (http://72.93.48.39:8080/xxx/abc/) and for certain reasons, i am forced to choose a different IP everytime. and i think its really not the right way to deploy the application. I would like to know what other people do in such scenarios? On thinking about it, i thought i could make it pickup values from the HTMLVars of the HTML wrapper. but that again has to be edited everytime again and again. will it be possible to be able to supply these values : server's ip address, server's port number(in case its not 8080 on some machine) at build time? if so can anyone give me a barbones sample build.xml just as an example?

  • About data size filled in the buffer

    - by Bohan Lu
    I need low-latency audio in my project, and I know Android 2.3 supports OpenSL ES. I have read documents and sample code and I decide to use Android simple buffer queue to do the play and record. I now try to write a simple application to do the test. However, I have some questions about recording. If I set the recorder stop when it is recording, how do I know the exact number of bytes filled in the last buffer if it is not filled up ? In 1.1 version, the callback function has some parameters about buffer and its filled data, but there is no such parameters in version 1.0.1. Is there any way to get this information ? Any suggestion would be greatly appreciated !

  • Lexing newlines in scala StdLexical?

    - by Nick Fortescue
    I'm trying to lex (then parse) a C like language. In C there are preprocessor directives where line breaks are significant, then the actual code where they are just whitespace. One way of doing this would be do a two pass process like early C compilers - have a separate preprocessor for the # directives, then lex the output of that. However, I wondered if it was possible to do it in a single lexer. I'm pretty happy with writing the scala parser-combinator code, but I'm not so sure of how StdLexical handles whitespace. Could someone write some simple sample code which say could lex a #include line (using the newline) and some trivial code (ignoring the newline)? Or is this not possible, and it is better to go with the 2-pass appproach?
