• scipy.io typeerror:buffer too small for requested array

  - by kartiku

  I have a problem in python. I'm using scipy, where i use scipy.io to load a .mat file. The .mat file was created using MATLAB. listOfFiles = os.listdir(loadpathTrain) for f in listOfFiles: fullPath = loadpathTrain + '/' + f mat_contents = sio.loadmat(fullPath) print fullPath Here's the error: Traceback (most recent call last): File "tryRankNet.py", line 1112, in demo() File "tryRankNet.py", line 645, in demo mat_contents = sio.loadmat(fullPath) File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/mio.py", line 111, in loadmat matfile_dict = MR.get_variables() File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/miobase.py", line 356, in get_variables getter = self.matrix_getter_factory() File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/mio5.py", line 602, in matrix_getter_factory return self._array_reader.matrix_getter_factory() File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/mio5.py", line 274, in matrix_getter_factory tag = self.read_dtype(self.dtypes['tag_full']) File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/miobase.py", line 171, in read_dtype order='F') TypeError: buffer is too small for requested array The whole thing is in a loop, and I checked the size of the file where it gives the error by loading it interactively in IDLE. The size is (9,521), which is not at all huge. I tried to find if I'm supposed to clear the buffer after each iteration of the loop, but I could not find anything. Any help would be appreciated. Thanks.

• [SOLVED] flash 10, as3 - save text of textarea and reuse it to replace text in textarea

  - by user427969

  hi everyone Is it possible to save text of textarea (flash 10, as3, cs5) in some variable or so and with its textformat (more than one color) and then reuse it to replace text in textarea? I tried saving htmlText of textarea but the problem is when i replace it in textarea tags causes problem. There will always be another extra line. If anyone wants to view p tags problem try following. Just click on text and then move your down arrow key, cursor will go to next line. import fl.controls.TextArea; var txtHTML:TextArea = new TextArea(); txtHTML.move(0,0); var default_format:TextFormat = new TextFormat(); default_format.font = "Arial"; default_format.bold = false; default_format.align = "center"; default_format.color = 0xFFFF00; default_format.size = 14; var field:TextField = txtHTML.textField; field.defaultTextFormat = default_format; field.setTextFormat(default_format); field.alwaysShowSelection = true; field.background = true; field.type = 'input'; field.multiline = true; field.backgroundColor = 0x777777; field.embedFonts = true; txtHTML.htmlText = '<P ALIGN="CENTER"><FONT FACE="_sans" SIZE="14" COLOR="#FFFF00" LETTERSPACING="0" KERNING="0">ASDF</FONT></P>'; field.x = 0; field.y = 0; field.width = 400; field.height = 200; field.text = ""; addChild(txtHTML); Is there a way to do this? Thanks alot for any help. Regards

• - (void)keyboardWasShown not called when switching to another UITextField

  - by Shawn

  I'm having a strange problem that I don't understand. I have a UIScrollView with several UITextField objects. When I switch to the view, I set the first UITextField as firstresponder, and the keyboardWasShown method gets called due to the UIKeyboardDidShowNotification that the view is registered for. The weird thing is, when I touch the next UITextField, the keyboardWasShown method is not called. I don't understand this, since Apple's documentation says "If your interface has multiple text fields, the user can tap between them to edit the values in each one. When that happens, however, the keyboard does not disappear but the system does still generate UIKeyboardDidShowNotification notifications each time editing begins in a new text field." My code I've copied directly from Apple's documentation as well, and it works properly, but it only gets called the first time. What am I missing? - (void)registerForKeyboardNotifications { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardDidHideNotification object:nil]; } - (void)keyboardWasShown:(NSNotification *)aNotification { //if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; CGSize kbSize = [[info objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue].size; CGRect bkgndRect = activeField.superview.frame; bkgndRect.size.height += kbSize.height; [activeField.superview setFrame:bkgndRect]; [scrollView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y) animated:YES]; keyboardShown = YES; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; }

• Uploading image with AsynFileUpload(ACT Control) and changing Image Url of an Image Control??

  - by mahdiahmadirad

  Hi! I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel: <asp:UpdatePanel ID="UpdatePanelNew" runat="server"> <ContentTemplate> <asp:Image ID="Image1" ImageUrl="~/Images/Categories/NoCategory.png" runat="server" /> </ContentTemplate> </asp:UpdatePanel> <asp:AsyncFileUpload OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete" runat="server" ID="AsyncFileUpload1" UploadingBackColor="#CCFFFF" ThrobberID="myThrobber" /> &nbsp; <asp:Label ID="myThrobber" runat="server" Style="display: none;"> <img align="middle" alt="Working..." src="../../Images/App/uploading.gif" /> </asp:Label> in C# code I wrote these: protected void Page_Init() { AsyncFileUpload1.UploadedComplete += new EventHandler<AsyncFileUploadEventArgs>(AsyncFileUpload1_UploadedComplete); } void AsyncFileUpload1_UploadedComplete(object sender, AsyncFileUploadEventArgs e) { ScriptManager.RegisterStartupScript(this, this.GetType(), "size", "top.$get(\"" + uploadResult.ClientID + "\").innerHTML = 'Uploaded size: " + AsyncFileUpload1.FileBytes.Length.ToString() + "';", true); string savePath = MapPath("~/Images/Categories/" + Path.GetFileName(e.filename)); ImageOperations.ResizeFromStream(savePath, 128, AsyncFileUpload1.FileContent); Image1.ImageUrl = "~/Images/Categories/" + AsyncFileUpload1.FileName; //AsyncFileUpload1.SaveAs(savePath); } But it does not work. can you help me? Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I used UpdatePanelNew.Update(); but it does not work!

• What's the best way to fill or paint around an image in Java?

  - by wsorenson

  I have a set of images that I'm combining into a single image mosaic using JAI's MosaicDescriptor. Most of the images are the same size, but some are smaller. I'd like to fill in the missing space with white - by default, the MosaicDescriptor is using black. I tried setting the the double[] background parameter to { 255 }, and that fills in the missing space with white, but it also introduces some discoloration in some of the other full-sized images. I'm open to any method - there are probably many ways to do this, but the documentation is difficult to navigate. I am considering converting any smaller images to a BufferedImage and calling setRGB() on the empty areas (though I am unsure what to use for the scansize on the batch setRGB() method). My question is essentially: What is the best way to take an image (in JAI, or BufferedImage) and fill / add padding to a certain size? Is there a way to accomplish this in the MosaicDescriptor call without side-effects? For reference, here is the code that creates the mosaic: for (int i = 0; i < images.length; i++) { images[i] = JPEGDescriptor.create(new ByteArraySeekableStream(images[i]), null); if (i != 0) { images[i] = TranslateDescriptor.create(image, (float) (width * i), null, null, null); } } RenderedOp finalImage = MosaicDescriptor.create(ops, MosaicDescriptor.MOSAIC_TYPE_OVERLAY, null, null, null, null, null);

• fast similarity detection

  - by reinierpost

  I have a large collection of objects and I need to figure out the similarities between them. To be exact: given two objects I can compute their dissimilarity as a number, a metric - higher values mean less similarity and 0 means the objects have identical contents. The cost of computing this number is proportional to the size of the smaller object (each object has a given size). I need the ability to quickly find, given an object, the set of objects similar to it. To be exact: I need to produce a data structure that maps any object o to the set of objects no more dissimilar to o than d, for some dissimilarity value d, such that listing the objects in the set takes no more time than if they were in an array or linked list (and perhaps they actually are). Typically, the set will be very much smaller than the total number of objects, so it is really worthwhile to perform this computation. It's good enough if the data structure assumes a fixed d, but if it works for an arbitrary d, even better. Have you seen this problem before, or something similar to it? What is a good solution? To be exact: a straightforward solution involves computing the dissimilarities between all pairs of objects, but this is slow - O(n2) where n is the number of objects. Is there a general solution with lower complexity?

• Making REST request using LWP::Simple

  - by Alienfluid

  I am trying to use LWP::Simple to make a GET request to a REST service. Here's the simple code: use LWP::Simple; $uri = "http://api.stackoverflow.com/0.8/questions/tagged/php"; $jsonresponse= get $uri; print $jsonresponse; On my local machine, running Ubuntu 10.4, and Perl version 5.10.1: farhan@farhan-lnx:~$ perl --version This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi I can get the correct response and have it printed on the screen. E.g.: farhan@farhan-lnx:~$ head -10 output.txt { "total": 1000, "page": 1, "pagesize": 30, "questions": [ { "tags": [ "php", "arrays", "coding-style" (... snipped ...) But on my host's machine to which I SSH into, I get garbage printed on the screen for the same exact code. I am assuming it has something to do with the encoding, but the REST service does not return the character set type in the response, so how do I force LWP::Simple to use the correct encoding? Any ideas what may be going on here? Here's the version of Perl on my host's machine: [dredd]$ perl --version This is perl, v5.8.8 built for x86_64-linux-gnu-thread-multi

• Rails Autocompletion Issue - Rails 1.2.3 to 2.3.5

  - by Grant Sayer

  I have an issue with rails Autocompletion from some code that i've inherited from an old Rails 1.2.3 project that I'm porting to Rails 2.3.5. The issue revolves around javascript execution within the auto_complete helper :after_update_element. The scenario is: A user is presented with a popup form with a number of fields. In the first field as they enter text the auto_complete AJAX call occurs, returning a result, plus a series of other HTML data wrapped in <divs> so that the after_update_element call can iterate over the other data and fill in the remaining fields. The issue lies with the extraction of the other fields which works on IE, fails on Firefox. Here is the code: <%= text_field_with_auto_complete :item, :product_code, {:value => ""}, {:size => 40, :class => "input-text", :tabindex => 6, :select => 'code', :with => "element.name + '=' + escape(element.value) + '&supplier_id=' + $('item_supplier_id').value", :after_update_element => "function (ele, value) { $('item_supplier_id').value = Utilities.extract_value(value, 'supplier_id'); $('item_supplied_size').value = Utilities.extract_value(value, 'size')}"}%> Now the function Utilities is designed to grab the fields from the string of values and looks like: // // Extract a particular set of data from the autocomplete actions // Utilities.extract_value = function (value, className) { var result; var elements = document.getElementsByClassName(className, value); if (elements && elements.length == 1) { result = elements[0].innerHTML.unescapeHTML(); } return result; }; In Firefox the value of result is undefined

• 3x3 Sobel operator and gradient features

  - by pithyless

  Reading a paper, I'm having difficulty understanding the algorithm described: Given a black and white digital image of a handwriting sample, cut out a single character to analyze. Since this can be any size, the algorithm needs to take this into account (if it will be easier, we can assume the size is 2^n x 2^m). Now, the description states given this image we will convert it to a 512-bit feature (a 512-bit hash) as follows: (192 bits) computes the gradient of the image by convolving it with a 3x3 Sobel operator. The direction of the gradient at every edge is quantized to 12 directions. (192 bits) The structural feature generator takes the gradient map and looks in a neighborhood for certain combinations of gradient values. (used to compute 8 distinct features that represent lines and corners in the image) (128 bits) Concavity generator uses an 8-point star operator to find coarse concavities in 4 directions, holes, and lagrge-scale strokes. The image feature maps are normalized with a 4x4 grid. I'm for now struggling with how to take an arbitrary image, split into 16 sections, and using a 3x3 Sobel operator to come up with 12 bits for each section. (But if you have some insight into the other parts, feel free to comment :)

• Automatically support new changes with Python.

  - by Zachary Brown

  I was working on a program,that I need to support new additions. Hmmm. Let me give you some background on the program. It is an educational software program that has quizzes for the user to take, just to gain odd knowledge. Now, It currently supports 6 subjects, all organized with directores on the HDD ( i.e. the Science directory is called science. ) and the way you launch the subject to see what quizzes you have to take is by pushing a button on the home screen. This sort of thing prevents easy subject additions. I want to be able to add a subject later on without having to recode the home screen and re organize all the buttons. I would use a Listbox and os.listdir(...), but I was kind of wanting something prettier than a Listbox. I am using Tkinter on Windows. The Python version I am using is 2.6 Is there a "fancy" listbox sort of thing that can be styled to work with the background?

• Adding AJAX call to function triggered popup blocker

  - by jerrygarciuh

  Hi folks, I have a client who wants to open variously sized images in a centered popup. I tried to get them to use FancyBox but they don't want interstitial presentation, so... I initially was opening a generic popup which resized and centered onload based on image size but they don't like the shift so I added a PHP script to echo the sizes and used jQuery to fetch the size info to feed into the pop up call. But it appears the delay this causes is setting off all popup blockers. Here is the JS $("#portfolioBigPic").click(function () { var src = $("#portfolioBigPic").attr('src'); var ar = src.split('/'); var fname = ar.pop(); fname = '/g/portfolio/clients/big/' + fname; $.get("imgsize.php", { i: fname}, function(data){ var dim = data.split(","); popit(fname,dim[0],dim[1]); }); }); function popit(img,w,h) { var features = 'width='+w+',height='+h+', toolbar=0, location=0, directories=0, status=0, menubar=0, scrollbars=0, resizable=1,'; var left = (screen.width/2)-(w/2); var top = 0; features += 'top='+top+',left='+left; bigpic = window.open('portfolioBigPic.php?img='+img, 'bigpic',features); bigpic.focus(); } The only difference between dodging the blockers and failing is that I added the AJAX .get and use it to specify w and h. Any thoughts on how to avoid this? Maybe I should use PHP to get widths and heights of all the big pics and write a JS array of them when this page loads? Am I right that the delay caused by fetching the data is tripping the blockers? Thoughts? Any advice much appreciated. JG

• Linux PDF/Postscript Optimizing

  - by Sheldon Ross

  So I have a report system built using Java and iText. PDF templates are created using Scribus. The Java code merges the data into the document using iText. The files are then copied over to a NFS share, and a BASH script prints them. I use acroread to convert them to PS, then lpr the PS. The FOSS application pdftops is horribly inefficient. My main problem is that the PDF's generated using iText/Scribus are very large. And I've recently run into the problem where acroread pukes because it hits 4gb of mem usage on large (300+ pages) documents. (Adobe is painfully slow at updating stuff to 64 bit). Now I can use Adobe reader on Windows, and use the Create Print PDF option or whatever its called, and it greatly( 10x) reduces the size of the PDF(it removes alot of metadata about form fields and such it appears) and produces a PDF that is basically a Print image. My question is does anyone know of a good solution/program for doing something similiar on Linux. Ideally, it would optimize the PDF, reduce size, and reduce PS complexity so the printer could print faster as it takes about 15-20 seconds a page to print right now.

• Post a form from asp to asp.Net

  - by Atomiton

  I have a classic asp application. I want to post a contest form from that page to an Asp.Net form. The reason is that I want to use a lot of logic i have built into an Asp.Net page for validation before entering into the database and I don't know asp very well. Not to mention asp.Net being more secure. What's the best way to accomplish this goal? My thoughts are as follows: My asp Page: <html> <body> <form action="/Contests/entry.aspx" method="post"> Name: <input type="text" name="fname" size="20" /> Last Name: <input type="text" name="lname" size="20" /> <input type="submit" value="Submit" /> </form> </body> </html> aspx page is running in a Virtual Directory and would handle anything posted to it. Is this possible, or does aspx prevent this kind of thing? I ( preferably ) don't want to create the form in aspx as my colleague wants to have control of the page and build the html himself and I don't want the hassle of constantly changing it. Are there caveats I need to consider? What roadblocks will I run into? How do I access the Posted Form Values? Request.Form?

• Inline image and caption in article - conform caption's width to image's width

  - by Micah

  Here's my code: <div class="image"> <img src="image.jpg" alt="Image description" /> <p class="caption">This is the image caption</p> </div> Here's my CSS: .image { position: relative; float: right; margin: 8px 0 10px 10px; } .caption { font-weight: bold; color: #444666; } As is above, the caption will conform to the width of div.image. My problem is often the img varies in size, from 100px width to 250px width. I'd like to make the caption width conform to the corresponding width of the image, no matter the size. While I'd love for this to be more semantic as well, I'm not sure how easy it would be to switch p.caption with img. Of course, I'd prefer that method but am taking this a step at a time. Is there some jquery code that I can use to detect the width of the image and add that width as an inline style to the caption tag? Is there a better way to do this? I'm open to suggestions.

• Problem with non blocking fifo in bash

  - by timdel

  Hi! I'm running a few Team Fortress 2 servers and I want to write a little management script. Basically the TF2 servers are a fg process which provides a server console, so I can start the server, type status and get an answer from it: ***@purple:~/tf2$ ./start_server_testing Auto detecting CPU Using AMD Optimised binary. Server will auto-restart if there is a crash. Console initialized. [bla bla bla] Connection to Steam servers successful. VAC secure mode is activated. status hostname: Team Fortress version : 1.0.6.1/15 3883 secure udp/ip : ***.***.133.31:27600 map : ctf_2fort at: 0 x, 0 y, 0 z players : 0 (2 max) # userid name uniqueid connected ping loss state adr Great, now I want to create a script which sends the command sm_reloadadmins to all my servers. The best way I found to do this is using a fifo named pipe. Now what I want to do is having this pipe readonly and non blocking to the server process, so I can write into the pipe and the server executes it, but still I want to write via console one the server, so if I switch back to the fg process of the server and I type status I want an answer printed. I tried this (assuming serverfifo is mkfifo serverfifo): ./start_server_testing < serverfifo Not working, the server won't start until something is written to the pipe. ./start_server_testing <> serverfifo Thats actually working pretty good, I can see the console output of the server and I can write to the fifo and the server executes the commands, but I can't write via console to the server anymore. Also, if I write 'exit' to the pipe (which should end the server) and I'm running it in a screen the screen window is getting killed for some reason (wtf why?). I only need the server to read the fifo without blocking AND all my keyboard input on the server itself should be send to the server AND all server ouput should be written to the console. Is that possible? If yes, how?

• PHP PCRE differences on testing and hosting servers

  - by Gary Pearman

  Hi all, I've got the following regular expression that works fine on my testing server, but just returns an empty string on my hosted server. $text = preg_replace('~[^\\pL\d]+~u', $use, $text); Now I'm pretty sure this comes down to the hosting server version of PCRE not being compiled with Unicode property support enabled. The differences in the two versions are as follows: My server: PCRE version 7.8 2008-09-05 Compiled with UTF-8 support Unicode properties support Newline sequence is LF \R matches all Unicode newlines Internal link size = 2 POSIX malloc threshold = 10 Default match limit = 10000000 Default recursion depth limit = 10000000 Match recursion uses stack Hosting server: PCRE version 4.5 01-December-2003 Compiled with UTF-8 support Newline character is LF Internal link size = 2 POSIX malloc threshold = 10 Default match limit = 10000000 Match recursion uses stack Also note that the version on the hosting server (the same version PHP is compiled against) is pretty old. What confuses me though, is that pcretest fails on both servers from the command line with re> ~[^\\pL\d]+~u ** Unknown option 'u' although this regexp works fine when run from PHP on my server. So, I guess my questions are does the regular expression fail on the hosting server because of the lack of Unicode properties? Or is there something else that I'm missing? Thanks all, Gaz.

• Checking for Repeated Strings in 2d list

  - by Zach Santiago

  i have a program where i have a list of names and classes. i have the list in alphabetical order. now im trying to check if names repeat, add the classes to one single name. im trying to write some code like go through names if name is already in list, add the class to the one name. so an example would be, instead of having 'Anita ','phys 1443', and 'Anita','IE 3312' i would just have 'Anita','PHYS 1443','IE 3312'. How would i go about doing this in a logival way, WITHOUT using any sort of built in functions? i tried comparing indexe's like if list[i][0] == list[i+1][0], append list[i+1][1] to an emptylist. while that almost worked, it would screw up at some points along the way. here is my attempt size = len(c) i = 0 c = [['Anita', 'PHYS 1443'], ['Anita', 'IE 3312'], ['Beihuang', 'PHYS 1443'], ['Chiao-Lin', 'MATH 1426'], ['Chiao-Lin', 'IE 3312'], ['Christopher', 'CSE 1310'], ['Dylan', 'CSE 1320'], ['Edmund', 'PHYS 1443'], ['Ian', 'IE 3301'], ['Ian', 'CSE 1320'], ['Ian', 'PHYS 1443'], ['Isis', 'PHYS 1443'], ['Jonathan', 'MATH 2325'], ['Krishna', 'MATH 2325'], ['Michael', 'IE 3301'], ['Nang', 'MATH 2325'], ['Ram', 'CSE 1320'], ['Taesu', 'CSE 1320'], ["Tre'Shaun", 'IE 3312'], ["Tre'Shaun", 'MATH 2325'], ["Tre'Shaun", 'CSE 1310']] ## Check if any names repeat d.append(c[0][0]) while i < size - 1 : if c[i][0] == c[i+1][0] : d.append(c[i][1]) d.append(c[i+1][1]) else : d.append(c[i+1][0]) d.append(c[i+1][1]) i = i + 1 print d output was. ['Anita', 'PHYS 1443', 'IE 3312', 'Beihuang', 'PHYS 1443', 'Chiao-Lin', 'MATH 1426', 'MATH 1426', 'IE 3312', 'Christopher', 'CSE 1310', 'Dylan', 'CSE 1320', 'Edmund', 'PHYS 1443', 'Ian', 'IE 3301', 'IE 3301', 'CSE 1320', 'CSE 1320', 'PHYS 1443', 'Isis', 'PHYS 1443', 'Jonathan', 'MATH 2325', 'Krishna', 'MATH 2325', 'Michael', 'IE 3301', 'Nang', 'MATH 2325', 'Ram', 'CSE 1320', 'Taesu', 'CSE 1320', "Tre'Shaun", 'IE 3312', 'IE 3312', 'MATH 2325', 'MATH 2325', 'CSE 1310']

• Marquee style progressbar in wxPython

  - by Mridang Agarwalla

  Hi, Could anyone tell me how to implement a marquee style progress bar in wxPython? As stated on MSDN: you can animate it in a way that shows activity but does not indicate what proportion of the task is complete. Thank you. I tried this but it doesn't seem to work. The timer ticks but the gauge doesn't scroll. Any help? import wx import time class MyForm(wx.Frame): def __init__(self): wx.Frame.__init__(self, None, wx.ID_ANY, "Timer Tutorial 1", size=(500,500)) # Add a panel so it looks the correct on all platforms panel = wx.Panel(self, wx.ID_ANY) self.timer = wx.Timer(self) self.Bind(wx.EVT_TIMER, self.update, self.timer) self.gauProgress = wx.Gauge(panel, range=1000, pos=(30, 50), size=(440, 20)) self.toggleBtn = wx.Button(panel, wx.ID_ANY, "Start") self.toggleBtn.Bind(wx.EVT_BUTTON, self.onToggle) def onToggle(self, event): btnLabel = self.toggleBtn.GetLabel() if btnLabel == "Start": print "starting timer..." self.timer.Start(1000) self.toggleBtn.SetLabel("Stop") else: print "timer stopped!" self.timer.Stop() self.toggleBtn.SetLabel("Start") def update(self, event): print "\nupdated: ", print time.ctime() self.gauProgress.Pulse() # Run the program if __name__ == "__main__": app = wx.PySimpleApp() frame = MyForm().Show() app.MainLoop()

• Is there any danger in calling free() or delete instead of delete[]? [closed]

  - by Matt Joiner

  Possible Duplicate: ( POD )freeing memory : is delete[] equal to delete ? Does delete deallocate the elements beyond the first in an array? char *s = new char[n]; delete s; Does it matter in the above case seeing as all the elements of s are allocated contiguously, and it shouldn't be possible to delete only a portion of the array? For more complex types, would delete call the destructor of objects beyond the first one? Object *p = new Object[n]; delete p; How can delete[] deduce the number of Objects beyond the first, wouldn't this mean it must know the size of the allocated memory region? What if the memory region was allocated with some overhang for performance reasons? For example one could assume that not all allocators would provide a granularity of a single byte. Then any particular allocation could exceed the required size for each element by a whole element or more. For primitive types, such as char, int, is there any difference between: int *p = new int[n]; delete p; delete[] p; free p; Except for the routes taken by the respective calls through the delete-free deallocation machinery?

• UIWebView in custom UITableViewCell

  - by mlecho

  i am not sure if this is a good route to go,...i have some data i receive from the web which in turn, populates a table view. The problem is, the text is html (p tags, etc). My first thought was to create a uiwebview in the cell, and populate with loadHTMLString. Fact is , it KINDA works. But, i then the cell no longer was the recipient of touches. SO, before we get too deep in code, is there a better way to populate the cells, than using a UIWebView. It feels like a hack, and i fear even if it works, apple would turn it away. //from my custom UITableViewCell class: - (id)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) { [self setFrame:frame]; webcell = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,frame.size.width-20,frame.size.height)]; [self.contentView addSubview:webcell]; //bloack the webview from touches UIView *cover = [[UIView alloc] initWithFrame:webcell.frame]; [self.contentView addSubview:cover]; [cover release]; } return self; } -(void)setLabelData:(FeedItem *)feedItem { link = feedItem.link; NSMutableString *htmlstring = [NSMutableString string]; [htmlstring appendString:@"<html><head><link rel='stylesheet' href='style.css'/></head><body>"]; [htmlstring appendFormat:@"<p>%@</p>",feedItem.title]; [htmlstring appendFormat:@"<p>%@</p>",feedItem.description]; [htmlstring appendString:@"</body></html>"]; [webcell loadHTMLString:htmlstring baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]bundlePath]]]; } thanks

• Android : Bitmap save to location

  - by Chrispix

  I am working on a function to download an image from a web server, redisplay it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice? My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a Fileoutput stream to write the data. The other option I have is it use MediaStore : MediaStore.Images.Media.insertImage(getContentResolver(), bm, barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image"); Which works fine to save to SD card, but does not allow you to customize the folder. Any assistance would be very much appreciated. Thank you in advance.

• Why does my REST request return garbage data?

  - by Alienfluid

  I am trying to use LWP::Simple to make a GET request to a REST service. Here's the simple code: use LWP::Simple; $uri = "http://api.stackoverflow.com/0.8/questions/tagged/php"; $jsonresponse= get $uri; print $jsonresponse; On my local machine, running Ubuntu 10.4, and Perl version 5.10.1: farhan@farhan-lnx:~$ perl --version This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi I can get the correct response and have it printed on the screen. E.g.: farhan@farhan-lnx:~$ head -10 output.txt { "total": 1000, "page": 1, "pagesize": 30, "questions": [ { "tags": [ "php", "arrays", "coding-style" (... snipped ...) But on my host's machine to which I SSH into, I get garbage printed on the screen for the same exact code. I am assuming it has something to do with the encoding, but the REST service does not return the character set type in the response, so how do I force LWP::Simple to use the correct encoding? Any ideas what may be going on here? Here's the version of Perl on my host's machine: [dredd]$ perl --version This is perl, v5.8.8 built for x86_64-linux-gnu-thread-multi

• Add autoFill capabilities to jQuery-UI 1.8.1

  - by rockinthesixstring

  here's what I currently have, unfortunately I cannot seem to figure out how to get autoFill to work with jQuery-UI... It used to work with the straight up Autocomplete.js <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js" type="text/javascript"></script> <script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.1.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> var thesource = "RegionsAutoComplete.axd?PID=3" $(function () { function log(message) { $("<div/>").text(message).prependTo("#log"); $("#log").attr("scrollTop", 0); } $.expr[':'].textEquals = function (a, i, m) { return $(a).text().match("^" + m[3] + "$"); }; $("#birds").autocomplete({ source: thesource, change: function (event, ui) { //if the value of the textbox does not match a suggestion, clear its value if ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0) { $(this).val(''); } else { log(ui.item ? ("Selected: " + ui.item.value + " aka " + ui.item.id) : "Nothing selected, input was " + this.value); } } }).live('keydown', function (e) { var keyCode = e.keyCode || e.which; //if TAB or RETURN is pressed and the text in the textbox does not match a suggestion, set the value of the textbox to the text of the first suggestion if ((keyCode == 9 || keyCode == 13) && ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0)) { $(this).val($(".ui-autocomplete li:visible:first").text()); } }); }); </script> I've used the answer here to get the mustMatch working, but unfortunately if I "tab" away from the input box, I get the "Nothing selected" response instead of an Value and ID. Does anyone know how to extract the ID out of the autocomplete when you don't actually select the field?
