• UIView Horizontal scroll for a part of a screen

  - by Futur

  Hi Friends, I have a requirement for scrolling a part of a view horizontally. there are 2 views, mainView(0,70,320*2,400) and a horizontalView(0,0,320*2,160)[this horizontalView has an internal UIScrollView with the same frame] So the horizontal view will occupy the first section of the screen and it should only be scrollable horizontally (and the other part of the mainView - the other part of the screen should be static). how to achieve this? i am getting a general scroll for the whole page not for the first section alone. am i in the right direction for this problem? please advice Thank you

• Why are all my masked views unmasked in my view snapshot?

  - by mystify

  I'm taking a snapshot of an view. This view has got some subviews which have layer masks applied to them. For some reason, those masks take no effect in the snapshot and the masked parts are completely visible. UIGraphicsBeginImageContext(theView.frame.size); [theView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); I assume this is a bug in the framework. But maybe it's not? Did I do anything wrong here?

• Is there an optimal way to render images in cocoa? Im using setNeedsDisplay

  - by Edward An

  Currently, any time I manually move a UIImage (via handling the touchesMoved event) the last thing I call in that event is [self setNeedsDisplay], which effectively redraws the entire view. My images are also being animated, so every time a frame of animation changes, i have to call setNeedsDisplay. I find this to be horrific since I don't expect iphone/cocoa to be able to perform such frequent screen redraws very quickly. Is there an optimal, more efficient way that I could be doing this? Perhaps somehow telling cocoa to update only a particular region of the screen (the rect region of the image)?

• Visual C++ 2008 Intellisense is not displaying DocXml comments

  - by DavidTM

  In Visual C++ 2008, I have documented a method with DocXML: /// <summary>Function to generate and map channel.</summary> /// <param name="a_cfi">Raw CFI (1, 2 or 3)</param> /// <param name="a_ns">Slot number in frame</param> static void myFunc(unsigned a_cfi, unsigned a_ns); Intellisense displays this, but it displays the actual tags (i.e. precisely as shown above) instead of recognizing the tags and formatting the text accordingly. How can I fix this please?

• Standardizing camera input in OpenCV? (Contrast/Saturation/Brightness etc..)

  - by karpathy

  I am building an application using OpenCV that uses the webcam and runs some vision algorithms. I would like to make this application available on the internet after I am done, but I am concerned about the vast differences in camera settings on every computer, and I am worried that the algorithm may break if the settings are too different from mine. Is there any way, after capturing the frame, to post process it and make sure that the contrast is X, brightness is Y, and saturation is Z? I think the Camera settings themselves can not be changed from code directly using the current OpenCV Python bindings. Would anyone be able to tell me about how I could calculate some of these parameters from the image and adjust them appropriately using OpenCV?

• HTML IFrame Help

  - by Josh K

  Hey Few Questions 1.Is it legal to have an IFrame on a website which inside has an external website? 2.In an IFrame is it possible to only show a section of the src that isnt the top left of the site (for instance if there was a chart in the middle of a website, could u have just the chart in your Iframe, or atleast start it centred there) 3.Any way to stop my IFrame from auto redirecting me to the external site for 3: ie <iframe src="http://fifa.com"></iframe> Just sends me to fifa instead of actually showing that site in a frame.

• Help using Lisp debugger

  - by Joel

  I'm trying understand how to interpret the output of, and use, the Lisp debugger. I've got a pretty simple Backtrace for the evaluation of my function, but I cann't seem to work out how to use it to find out in which Lisp 'form' in my function the exception occurred. I'd appreciate any clues as to what I should be doing, to find the source of the error. I've attached a screen shot (if it's too small to read I can re-post it in parts), with the debug output, the function and the repl (please ignore my very wrong function, I'm just interested in learning how to use the debugger properly). In addition, I hit 'v' on the first frame to go to the source, but this resulted in the error at the bottom of the screen.

• Sound plays multiple times at once

  - by Jr. Mathews

  I'm having trouble with sound in Flash. I may have went about coding the wrong way, because most of my codes are on frames. So, I have these two variables var outsideDay:Sound = new daysong(); var outsideNight:Sound = new nightsong(); And I want to play these songs on a specific frame. However, the sounds play sporadically, like 50 times at once. I think it's because I have other codes that link to the frames with a Enter_Frame function. How can I get the sounds to loop and not play multiple times at once?

• Java/Swing: Problem with key listener

  - by Mike

  I have a search dialog with a JTextField that's being used as a search box. When the user types something, it searches the DB, shows the result in a JTable and selects the first item in it. If the first result is what they were looking for, I want to let them quickly accept the dialog, by pressing Enter (while the JTextField is focused). So I added a KeyListener to the JTextField and it's working OK. Now the problem: The user opens can open the dialog by pressing Enter when a "Search" button on the dialog's parent frame is focused. The dialog is displayed and the JTextField gets the keyReleased event (from the Enter key that displayed it), so it shows up and closes. If the user holds Enter down, then the JTextField receives the keyPressed, keyTyped and keyReleased events. How can I fix without resorting to ugly workarounds? Platform is Windows 7 x64, btw. Test NetBeans project here: http://dl.dropbox.com/u/6354360/KeyListenerTest.zip Thanks.

• How Do You Parse Column Data ?

  - by discwiz

  I am trying to parse a file generated by LGA Tracon that lists the position data for aircraft over a given time frame. The data of interest starts with TRACKING DATA and ends with SST and there are thousands of entries per file. The system generating the file, Common ARTS, is very rigid in its formatting and we can expect the column spacing to be consistent. Any help would be greatly appreciated. Thanks, Here is an image to preserve the exact formatting Here is a reduced text file. link text

• Printing UTF-16 strings in JSP is outputted as HTML encoding (&#xxxx)

  - by Ori Osherov

  Hello, When I try to print a UTF-16 string in JSP, specifically Hebrew, it ends up showing up as HTML encoding (&#xxxx). This problem occurs because I print an array of variables into the web page and then parse them. The variables are all UTF-16 strings, but once the servlet prints the variables, it becomes translated to HTML encoding. Is there any way to get rid of the encoding? Thanks in advance Edit for a bit more background: The JSP that I'm printing is not the entirety of the page. It's used in a manner I don't quite understand by a server app which prints the JSPs output into its built in page. As a result, I can't, for instance, use a tag because the will have already been placed somewhere else. This isn't a frame or anything like that. It's just redirected output.

• Preloading images from XML into Flash

  - by tykebikemike

  I know this has been asked to death, but I cant seem to find the answer i'm looking for... I've put together a simple Flash/XML image gallery and I would like to preload the images - Simple process. Get the XML data Preload the images When all images are preloaded, go to next frame Here is my code thus far: var myXML:XML = new XML(); myXML.ignoreWhite = true; myXML.load("xmltest.xml"); myXML.onLoad = function(success){ if(success){ var myImage = myXML.firstChild.childNodes; for (i=0; i<myImage.length; i++){ var imageNumber = i+1; var imageName = myImage[i].attributes.name; var imageURL = myImage[i].firstChild.nodeValue; trace('image #: ' + imageNumber); trace('image name: ' + imageName); trace('image url: ' + imageURL + '\n'); } } }

• R webscraping: interrogating for date and importance

  - by adam.888

  I am able to webscrape a table from a webpage containing news library(XML) webpage <- "http://www.tradingeconomics.com/calendar" tables <- readHTMLTable(webpage ) n.rows <- unlist(lapply(tables, function(t) dim(t)[1])) dfcal <- as.data.frame(tables$calendar) However I do not know how to interrogate for date or for importance. For example how could I webscrape news from Jan 2014? I am able to do this on the webpage by altering button settings, but how can I do it from within R? I was also not able to collect the importance column data. Also are there better ways for collecting economic news from within R? I have looked on http://www.rseek.org/ but could not find anything. Thank you for your help.

• Sockets: RAW or STREAM

  - by user1415536

  May be the question is a bit stupid, but I'll ask it. I read a lot about raw sockets in network, have seen several examples. So, basically with raw sockets it's possible to build own stack of headers, like stack = IP + TCP/UDP + OWN_HEADER. My question is, is it possible to get some kind of ready frame of first two(IP + TCP/UDP) from the linux kernel and then just append own header to them? The operating system in question is linux and the language is C. I cannot find any function which can do such a thing, but may be I'm digging in a wrong direction.

• Anova test in the loop and outputing the p-value in separate column

  - by Juanhijuan

  Once again I'm trying to get an answer. I am already stuck for like 5h with that so that's why I keep trying to get an answer. That's my data: id Sequence variable value 75 AAAAGAAAVANQGKK BiotinControl1_2 3893050.50 192 AAAAGAAAVANQGKK BiotinControl1_2 900604.61 3770 AAFTKLDQVWGSE BiotinControl1_2 90008.14 The code which I am trying to use to calculate the p-value: My Code: tbl_anv <- tbl_all_onlyK[,c("id", "BiotinControl1_2", "BiotinControl2", "BiotinControl3", "BiotinTreatment1_2", "BiotinTreatment2", "BiotinTreatment3", "Sequence")] tbl_reo <- melt(tbl_anv, measure.vars=2:7) set.seed(1) vars <- c("id", "BiotinControl1_2", "BiotinControl2", "BiotinControl3", "BiotinTreatment1_2", "BiotinTreatment2", "BiotinTreatment3", "Sequence") tbl_reo <- as.data.frame(tbl_reo) by(tbl_reo,tbl_reo$Sequence,function(x){ anova(lm(value ~ variable, data = x))$"Pr(>F)"[1] }) An error ocurs: There were 50 or more warnings (use warnings() to see the first 50) Anyway, how can I do that and export the p-value in the separate column. That's what I tried to do on my own: aov_test <- by(tbl_reo,tbl_reo$Sequence,function(x){ anova(lm(value ~ variable, data = x))$"Pr(>F)"[1] }) tbl_reo[,5] <- aov.test[[1]]$'Pr(>F)'[1]

• R storing a complex search as a string

  - by Tahnoon Pasha

  Hi I'm working with a large data frame that I frequently need to subset in different combinations of variables. I'd like to be able to store the search in a string so I can just refer to the string when I want to see a subset. x = read.table(textConnection(" cat1 cat2 value A Z 1 A Y 2 A X 3 B N 2"),header=T,strip.white=T) search_string="cat1== 'A' & cat2=='Z'" with(x,subset(x,search)) doesn't work. What I'd be looking for is the result of a search similar to the one below. with(x,subset(x,cat1=='A' & cat2=='Z')) I'd prefer not to just create multiple subsetted data frames at the start if another solution exists. Is there a simple way to do what I'm trying?

• The shortest way to convert infix expressions to postfix (RPN) in C

  - by kuszi

  Original formulation is given here (you can try also your program for correctness) . Additional rules: 1. The program should read from standard input and write do standard output. 2. The program should return zero to the calling system/program. 3. The program should compile and run with gcc -O2 -lm -s -fomit-frame-pointer. The challenge has some history: the call for short implementations has been announced at the Polish programming contest blog in September 2009. After the contest, the shortest code was 81 chars long. Later on the second call has been made for even shorter code and after the year matix2267 published his solution in 78 bytes: main(c){read(0,&c,1)?c-41&&main(c-40&&(c%96<27||main(c),putchar(c))):exit(0);} Anyone to make it even shorter or prove this is impossible?

• MySQL - how to retrieve columns in same row as the values returned by min/mx

  - by Gala101

  I couldn't frame the Question's title properly.. Suppose a table of weekly movie Earnings as below, MovieName MovieGross WeekofYear Year So how do I get the names of top grossers for each week of this year If I do select MovieName , Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear; Then obviously query wont run, select Max(MovieName) , Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear; would just give movies starting with lowest alphabet Is using group-concat and then substring-index the only option here? select substring_index(group_concat(MovieName order by MovieGross desc),',',1), Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear ; Seems clumsy.. Is there any better way of acieveing this?

• How to save an image in it's original format?

  - by Patrick Klug

  I am trying to figure out how I can get the original format of an image so that I can store it with the same encoding. It seems that the only way to save an Image is by using a BitmapEncoder but I don't know how I can get the correct format from the image. Example: Clipboard.GetImage() returns a InteropBitmap which doesn't seem to contain any information about the original format. I also tried using an Extension method: public static void Save(this BitmapImage image, System.IO.Stream stream) { var decoder = BitmapDecoder.Create(image.StreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default); var encoder = BitmapEncoder.Create(decoder.CodecInfo.ContainerFormat); foreach (var frame in decoder.Frames) { encoder.Frames.Add(BitmapFrame.Create(decoder.Frames[0])); } encoder.Save(stream); } but the problem is that a) the ImageSource is not always a BitmapImage (Clipboard.GetImage()) for example and b) the image.StreamSource can be null in some cases (seems to be when the image is loaded via a relative Uri)

• NSTextField doesn't display text

  The NSTextField has a superview and a frame. It is fully visible and has the following declaration: - (id) initWithFrame: (NSRect) frameRect { if ((self = [super initWithFrame: NSMakeRect(0, 0, 300, 20)])) { label = [[NSTextField alloc] initWithFrame: NSMakeRect(47, 1, 233, 18)]; [[label cell] setAllowsUndo: NO]; [[label cell] setLineBreakMode: NSLineBreakByTruncatingMiddle]; [[label cell] setScrollable: NO]; [label setBezeled: NO]; [label setBordered: NO]; [label setDrawsBackground: NO]; [label setEditable: NO]; [label setFont: [NSFont menuFontOfSize: 14.0f]]; [label setSelectable: NO]; [label setTextColor: [NSColor textColor]]; [self addSubview: label]; NSLog(@"%@", NSStringFromRect([label visibleRect])); } return self; }

• plot only x and y axis (no box) in ggplot2

  - by Tyler Rinker

  The convention of some journals is to show only the x and y axis in a plot not a box around the entire plot area. How can I achieve this in ggplot2? I tried theme_minimal_cb_L from HERE but it seems to erase the entire box around the plot (does not leave the x and y axis) as seen here: Here's the code I'm using: dat <- structure(list(x = c(0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3), y1 = c(34, 30, 26, 23, 21, 19, 17, 16, 15, 13, 12, 12, 11), y2 = c(45, 39, 34, 31, 28, 25, 23, 21, 19, 17, 16, 15, 14)), .Names = c("x", "y1", "y2"), row.names = c(NA, -13L), class = "data.frame") library(reshape2); library(ggplot2) dat2 <- melt(dat, id='x') theme_minimal_cb_L <- function (base_size = 12, base_family = "", ...){ modifyList (theme_minimal (base_size = base_size, base_family = base_family), list (axis.line = element_line (colour = "black"))) } ggplot(data=dat2, aes(x=x, y=value, color=variable)) + geom_point(size=3) + geom_line(size=.5) + theme_minimal_cb_L()

• Identifying a function call in a python script line in runtime

  - by Dani

  I have a python script that I run with 'exec'. The script's string has calls to functions. When a function is called, I would like it to know the line number and offset in line for that call in the script (in the string I fed exec with). Here is an example. If my script is: foo1(); foo2(); foo1() foo3() And if I have code that prints (line,offset) in every function, I should get (0,0), (0,8), (0,16), (1,0) In most cases this can be easily done by getting the stack frame, because it contains the line number and the function name. The only problem is when there are two functions with the same name in a certain line. Unfortunately this is a common case for me. Any ideas?
