• need a near 100% uptime third-party web-accesible hosting for static web resources

  - by Jared Henderson

  I hope this makes sense: my business sells a website template, we currently have about 10,000 users. For various reasons that are unimportant to this question, I try to keep the file size of the zipped template we give them as small as possible. Because of this, I have taken a bunch of images and a couple of static files used by the template and moved them to external hosting. They are referenced by absolute URL in the css and markup, instead of shipping all of those images and files with every template. So, basically 10,000+ and growing users are requesting images and files from a third-party host. I don't use my own webhosting for this because I still kind of use a medium-cheap shared hosting for my website, and if it goes down, 10,000+ users are potentially effected. Currently I'm having the template directly access files inside of an open-source google-code project that I created for just this purpose. But, that seems like a bastardization of what a google-code repository is for, and plus, google code (i've found out) often spews 502 bad gateway errors for hours at a time. So, anyway, my question is: where is the right kind of place to host these? Obviously I'm willing to pay. My main needs are speed and uptime, since the images and files are being requested from thousands of different websites every day. Is this something that I should use Amazon S3 for? I'm guessing there's some kind of service exactly for this kind of need, but I'm at a loss to figure out what it is.

• Copy vector of values to vector of pairs in one line

  - by Kirill V. Lyadvinsky

  I have the following types: struct X { int x; X( int val ) : x(val) {} }; struct X2 { int x2; X2() : x2() {} }; typedef std::pair<X, X2> pair_t; typedef std::vector<pair_t> pairs_vec_t; typedef std::vector<X> X_vec_t; I need to initialize instance of pairs_vec_t with values from X_vec_t. I use the following code and it works as expected: int main() { pairs_vec_t ps; X_vec_t xs; // this is not empty in the production code ps.reserve( xs.size() ); { // I want to change this block to one line code. struct get_pair { pair_t operator()( const X& value ) { return std::make_pair( value, X2() ); } }; std::transform( xs.begin(), xs.end(), back_inserter(ps), get_pair() ); } return 0; } What I'm trying to do is to reduce my copying block to one line with using boost::bind. This code is not working: for_each( xs.begin(), xs.end(), boost::bind( &pairs_vec_t::push_back, ps, boost::bind( &std::make_pair, _1, X2() ) ) ); I know why it is not working, but I want to know how to make it working without declaring extra functions and structs?

• Access custom label property at didSelectRowAtIndexPath.

  - by Mr. McPepperNuts

  I have a UILabel for each cell at cellForRowAtIndexPath. UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; I want to access that string "myString" at didSelectRowAtIndexPath using indexpath. NSString *anotherString = cell.textLabel.text; returns null. Now if at cellForRowAtIndexPath, I did something like cell.textLabel.text = theString; then the didSelectRowAtIndexPath returns the appropriate cell. My question is, how can I access the text in the UILabel I apply to the cell, at didSelectRowAtIndexPath? Also, logging the cell in didSelectRowAtIndexPath returns cell: <UITableViewCell: 0x5dcb9d0; frame = (0 44; 320 44); autoresize = W; layer = <CALayer: 0x5dbe670>> Edit: NSString *myString = [[results objectAtIndex:indexPath.row] valueForKey:@"name"]; //cell.textLabel.text = myString; CGFloat width = [UIScreen mainScreen].bounds.size.width - 50; CGFloat height = 20; CGRect frame = CGRectMake(10.0f, 10.0f, width, height); UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; cellLabel.textColor = [UIColor blackColor]; cellLabel.backgroundColor = [UIColor whiteColor]; cellLabel.textAlignment = UITextAlignmentLeft; cellLabel.font = [UIFont systemFontOfSize:14.0f]; [cell.contentView addSubview:cellLabel]; [cellLabel release]; return cell;

• Resize view on iPhone when rotating

  - by BCBomb47

  I have an application with many views. I want only a couple of the views to be able to rotate to landscape when the device is rotated. I found out that I couldn't use (BOOL)shouldAutorotateToInterfaceOrientation because that would rotate every view in my app. I found a solution to this problem here on Stack Overflow but now I have another issue to deal with. The view rotates when I turn the device but it still shows the view as if it were still in portrait mode (straight up and down). The top and bottom of the view is cut off. Is there a way to have the view rotate and also adjust its size to fit the new orientation? I also found this but wasn't able to get it to work. Here's my code for that view: @implementation businessBank @synthesize webView, activityIndicator; - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = @"website_url"; NSURL *url = [NSURL URLWithString:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [webView loadRequest:requestObj]; [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; } - (void)didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[notification object] orientation]; if (orientation == UIDeviceOrientationLandscapeLeft) { [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)]; } else if (orientation == UIDeviceOrientationLandscapeRight) { [self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)]; } else if (orientation == UIDeviceOrientationPortraitUpsideDown) { [self.view setTransform:CGAffine TransformMakeRotation(M_PI)]; } else if (orientation == UIDeviceOrientationPortrait) { [self.view setTransform:CGAffineTransformMakeRotation(0.0)]; } }

• Why do System.IO.Log SequenceNumbers have variable length?

  - by Doug McClean

  I'm trying to use the System.IO.Log features to build a recoverable transaction system. I understand it to be implemented on top of the Common Log File System. The usual ARIES approach to write-ahead logging involves persisting log record sequence numbers in places other than the log (for example, in the header of the database page modified by the logged action). Interestingly, the documentation for CLFS says that such sequence numbers are always 64-bit integers. Confusingly, however, the .Net wrapper around those SequenceNumbers can be constructed from a byte[] but not from a UInt64. It's value can also be read as a byte[], but not as a UInt64. Inspecting the implementation of SequenceNumber.GetBytes() reveals that it can in fact return arrays of either 8 or 16 bytes. This raises a few questions: Why do the .Net sequence numbers differ in size from the CLFS sequence numbers? Why are the .Net sequence numbers variable in length? Why would you need 128 bits to represent such a sequence number? It seems like you would truncate the log well before using up a 64-bit address space (16 exbibytes, or around 10^19 bytes, more if you address longer words)? If log sequence numbers are going to be represented as 128 bit integers, why not provide a way to serialize/deserialize them as pairs of UInt64s instead of rather-pointlessly incurring heap allocations for short-lived new byte[]s every time you need to write/read one? Alternatively, why bother making SequenceNumber a value type at all? It seems an odd tradeoff to double the storage overhead of log sequence numbers just so you can have an untruncated log longer than a million terabytes, so I feel like I'm missing something here, or maybe several things. I'd much appreciate it if someone in the know could set me straight.

• Java Bucket Sort on Strings

  - by Michael

  I can't figure out what would be the best way to use Bucket Sort to sort a list of strings that will always be the same length. An algorithm would look like this: For the last character position down to the first: For each word in the list: Place the word into the appropriate bucket by current character For each of the 26 buckets(arraylists) Copy every word back to the list I'm writing in java and I'm using an arraylist for the main list that stores the unsorted strings. The strings will be five characters long each. This is what I started. It just abrubdly stops within the second for loop because I don't know what to do next or if I did the first part right. ArrayList<String> count = new ArrayList<String>(26); for (int i = wordlen; i > 0; i--) { for (int j = 0; i < myList.size(); i++) myList.get(j).charAt(i) } Thanks in advanced.

• Customize a WCF RIA Services EndpointRSS Feed

  - by Andrew Garrison

  Is it possible to customize the parameters of a WCF RIA Services endpoint? Specifically, I would like to create a custom binding for the endpoint and increase the maxReceivedMessageSize to allow sending the contents of a file that is a few megabytes in size. I've tried meddling in the web.config, but I'm getting the following error: [InvalidOperationException]: The contract name MyNamespace.MyService could not be found in the list of contracts implemented by the service MyNamespace.MyService web.config <system.serviceModel> <bindings> <customBinding> <binding name="CustomBinaryHttpBinding"> <binaryMessageEncoding /> <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> </customBinding> </bindings> <services> <service name="MyNamespace.MyService"> <endpoint address="" binding="wsHttpBinding" contract="MyNamespace.MyService" /> <endpoint address="/binary" binding="customBinding" bindingConfiguration="CustomBinaryHttpBinding" contract="MyNamespace.MyService" /> </service> </services> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel>

• How to implement an ListView containing images with style

  - by Alexandergre

  So I have been working with an app where I need to show the thumbnails as clean and use the space in a good way. Style A is my work until now. What I want to accomplish is something like style B. no titles and use the space in a good way. I need help with this. there was no tutorial on the net. Is ListView able to do such a thing? or shall I make picturesboxes and put them in a scrollview? the code: private void button1_Click(object sender, EventArgs e) { ImageList myImageList = new ImageList(); myImageList.ImageSize = new Size(48, 48); DirectoryInfo dir = new DirectoryInfo(@"C:\img"); foreach (FileInfo file in dir.GetFiles()) { try { myImageList.Images.Add(Image.FromFile(file.FullName)); } catch { Console.WriteLine("This is not an image file"); } } myListView.LargeImageList = myImageList; myListView.Items.Add("a", 0); myListView.Items.Add("b", 1); myListView.Items.Add("c", 2);

• Passing Variable Length Arrays to a function

  - by David Bella

  I have a variable length array that I am trying to pass into a function. The function will shift the first value off and return it, and move the remaining values over to fill in the missing spot, putting, let's say, a -1 in the newly opened spot. I have no problem passing an array declared like so: int framelist[128]; shift(framelist); However, I would like to be able to use a VLA declared in this manner: int *framelist; framelist = malloc(size * sizeof(int)); shift(framelist); I can populate the arrays the same way outside the function call without issue, but as soon as I pass them into the shift function, the one declared in the first case works fine, but the one in the second case immediately gives a segmentation fault. Here is the code for the queue function, which doesn't do anything except try to grab the value from the first part of the array... int shift(int array[]) { int value = array[0]; return value; } Any ideas why it won't accept the VLA? I'm still new to C, so if I am doing something fundamentally wrong, let me know.

• Custom Jquery slideshow doesn't want to reset?

  - by Jared

  Hello, Under $(document).ready(function(), I have the following code: num = $("#mainContentCategoryLinksWrapper > div").size(); This makes num equal the length of the children of #mainContentCategoryLinksWrapper. Currently, this equals 4. Above the $(document).ready(function( I have this: var timesRun = 0; function slideshow(){ if(timesRun < num){ $(".arrowIn").stop().animate({color: "#a12324", textIndent: "30px", backgroundPosition: '0px 0px'}, 100, function(){ //the first child in the series has a class of "arrowIn" $(".arrowIn").next().addClass("replaceMe"); //Adds the ".replaceMe" placeholder the the next element. $(".arrowIn").removeClass("arrowIn"); //Deletes the class on the current element $(".replaceMe").addClass("arrowIn").removeClass("replaceMe"); //reassigns ".arrowIn" over ".replaceMe" timesRun = timesRun + 1; //increases number of times run }).prev().animate({color: "#000000", textIndent: "25px", backgroundPosition: '0px -25px'}, {duration: 50}); //puts the previous element back to it's original position }else{ timesRun = 0; $(".arrowIn").removeClass("arrowIn"); $("#mainContentCategoryLinksWrapper:first-child").addClass("arrowIn"); //this is supposed to reset timesRun, and set the first child in the series back to the original ".arrowIn" } } setInterval( 'slideshow()', 1000 ); So here is the what the code does: 1) Animates the first in the series of 4 (#1) timesRun = 1 2) Animates the second in the series of 4 (#2) timesRun = 2 3) Animates the third in the series of 4 (#3) timesRun = 3 4) Animates the fourth in the series of 4 (#4) timesRun = 4 5) timesRun is now longer less than num. Reset class names back to original to .arrowIn, set timesRun to 0. However, when the slideshow() is reexectuted, it doesn't start over. Any ideas? See www.raceramps.com/v3 for an example.

• Setting MinimumSize Attribute for a Control in a TFS WorkItem

  - by Jay Yother

  Tools used: Visual Studio 2008 SP1 Team Explorer Team Foundation Server Power Tools October 2008 Release. Using the Process Editor in Visual Studio, I am attempting to set the MinimumSize attribute for a control in a WorkItem template to make the default size of the input area larger. I am setting the attribute according to this website: http://msmvps.com/blogs/vstsblog/archive/2007/07/07/undocumented-attributes-for-controlling-the-work-item-form-layout.aspx No matter what I set this attribute to it has no affect. I have tried setting the attribute with and without surrounding (). I've tried different capitalization of the attribute but no luck. I have verified that the MinimumSize attribute is being correctly set in the associated xml file. The control (HtmlFieldControl) is currently setup as the second child on a Tab Page. (The first control is also an HtmlFieldControl.) I've tried adding a group to the Tab Page such that the hierarchy is TabPage-Group-Column-Control with no success. I've also tried setting the attribute for the first control with no luck. Any idea what I am doing wrong?

• Lazy non-modifiable list

  - by mindas

  I was looking for a decent implementation of a generic lazy non-modifiable list implementation to wrap my search result entries. The unmodifiable part of the task is easy as it can be achieved by Collections.unmodifiableList() so I only need to sort out the the lazy part. Surprisingly, google-collections doesn't have anything to offer; while LazyList from Apache Commons Collections does not support generics. I have found an attempt to build something on top of google-collections but it seems to be incomplete (e.g. does not support size()), outdated (does not compile with 1.0 final) and requiring some external classes, but could be used as a good starting point to build my own class. Is anybody aware of any good implementation of a LazyList? If not, which option do you think is better: write my own implementation, based on google-collections ForwardingList, similar to what Peter Maas did; write my own wrapper around Commons Collections LazyList (the wrapper would only add generics so I don't have to cast everywhere but only in the wrapper itself); just write something on top of java.util.AbstractList; Any other suggestions are welcome.

• Replacing text inside textarea without focus

  - by asker

  I want to replace selected text(or insert new text after cursor position if nothing is selected). The new text is entered from another textbox. I want to be able to insert new text without clicking first (focusing) in the textarea. meaning: first select text to replace inside textarea, then enter new text into the textbox and click the button. <textarea id='text' cols="40" rows="20"> </textarea> <div id="opt"> <input id="input" type="text" size="35"> <input type="button" onclick='pasteIntoInput(document.getElementById("input").value)' value="button"/> </div> function pasteIntoInput(text) { el=document.getElementById("text"); el.focus(); if (typeof el.selectionStart == "number"&& typeof el.selectionEnd == "number") { var val = el.value; var selStart = el.selectionStart; el.value = val.slice(0, selStart) + text + val.slice(el.selectionEnd); el.selectionEnd = el.selectionStart = selStart + text.length; } else if (typeof document.selection != "undefined") { var textRange = document.selection.createRange(); textRange.text = text; textRange.collapse(false); textRange.select(); } } Online example: link text

• Moving a large number of files in one directory to multiple directories

  - by Axsuul

  I am looking to create a Windows batch script to move about 2,000 files and splitting them up so that there are 10 files per folder. I have attempted creating a batch script but the syntax really boggles my mind. Here is what I have so far @echo off :: Config parameters set /a groupsize = 10 :: initial counter, everytime counter is 1, we create new folder set /a n = 1 :: folder counter set /a nf = 1 for %%f in (*.txt) do ( :: if counter is 1, create new folder if %n% == 1 ( md folder%nf% set /a n += 1 ) :: move file into folder mv -Y %%f folder%nf%\%%f :: reset counter if larger than group size if %n% == %groupsize% ( set /a n = 1 ) else ( set /a n += 1 ) ) pause Basically what this script does is loop through each .txt file in the directory. It creates a new directory in the beginning and moves 10 files into that directory, then creates a new folder again and moves another 10 files into that directory, and so on. However, I'm having problems where the n variable is not being incremented in the loop? I'm sure there's other errors too since the CMD window closes on me even with pause. Any help or guidance is appreciated, thanks for your time!

• What is the fastest collection in c# to implement a prioritizing queue?

  - by Nathan Smith

  I need to implement a queue for messages on a game server so it needs to as fast as possible. The queue will have a maxiumem size. I need to prioritize messages once the queue is full by working backwards and removing a lower priority message (if one exists) before adding the new message. The appliation is asynchronous so access to the queue needs to be locked. I'm currently implementing it using a LinkedList as the underlying storage but have concerns that searching and removing nodes will keep it locked for too long. Heres the basic code I have at the moment: public class ActionQueue { private LinkedList<ClientAction> _actions = new LinkedList<ClientAction>(); private int _maxSize; /// <summary> /// Initializes a new instance of the ActionQueue class. /// </summary> public ActionQueue(int maxSize) { _maxSize = maxSize; } public int Count { get { return _actions.Count; } } public void Enqueue(ClientAction action) { lock (_actions) { if (Count < _maxSize) _actions.AddLast(action); else { LinkedListNode<ClientAction> node = _actions.Last; while (node != null) { if (node.Value.Priority < action.Priority) { _actions.Remove(node); _actions.AddLast(action); break; } } } } } public ClientAction Dequeue() { ClientAction action = null; lock (_actions) { action = _actions.First.Value; _actions.RemoveFirst(); } return action; } }

• Weird behaviour of C++ destructors

  - by Vilx-

  #include <iostream> #include <vector> using namespace std; int main() { vector< vector<int> > dp(50000, vector<int>(4, -1)); cout << dp.size(); } This tiny program takes a split second to execute when simply run from the command line. But when run in a debugger, it takes over 8 seconds. Pausing the debugger reveals that it is in the middle of destroying all those vectors. WTF? Note - Visual Studio 2008 SP1, Core 2 Duo 6700 CPU with 2GB of RAM. Added: To clarify, no, I'm not confusing Debug and Release builds. These results are on one and the same .exe, without even any recompiling inbetween. In fact, switching between Debug and Release builds changes nothing.

• How to read/write high-resolution (24-bit, 8 channel) .wav files in Java?

  - by dB'

  I'm trying to write a Java application that manipulates high resolution .wav files. I'm having trouble importing the audio data, i.e. converting the .wav file into an array of doubles. When I use a standard approach an exception is thrown. AudioFileFormat as = AudioSystem.getAudioFileFormat(new File("orig.wav")); --> javax.sound.sampled.UnsupportedAudioFileException: file is not a supported file type Here's the file format info according to soxi: dB$ soxi orig.wav soxi WARN wav: wave header missing FmtExt chunk Input File : 'orig.wav' Channels : 8 Sample Rate : 96000 Precision : 24-bit Duration : 00:00:03.16 = 303526 samples ~ 237.13 CDDA sectors File Size : 9.71M Bit Rate : 24.6M Sample Encoding: 32-bit Floating Point PCM Can anyone suggest the simplest method for getting this audio into Java? I've tried using a few techniques. As stated above, I've experimented with the Java AudioSystem (on both Mac and Windows). I've also tried using Andrew Greensted's WavFile class, but this also fails (WavFileException: Compression Code 3 not supported). One workaround is to convert the audio to 16 bits using sox (with the -b 16 flag), but this is suboptimal since it increases the noise floor. Incidentally, I've noticed that the file CAN be read by libsndfile. Is my best bet to write a jni wrapper around libsndfile, or can you suggest something quicker? Note that I don't need to play the audio, I just need to analyze it, manipulate it, and then write it out to a new .wav file. * UPDATE * I solved this problem by modifying Andrew Greensted's WavFile class. His original version only read files encoded as integer values ("format code 1"); my files were encoded as floats ("format code 3"), and that's what was causing the problem. I'll post the modified version of Greensted's code when I get a chance. In the meantime, if anyone wants it, send me a message.

• Memory Leaks when touching UITableViewCells and poping off view.

  - by Falcon

  Hi All, I'm currently having a problem where the leaks tool is reporting a slew of memory leaks after clicking on cells within a UITableView and then hitting the back button and popping off the view. Majority of the leaks reported can not be traced back to any specific location in my code, they are: Leaked Object # Address Size Responsible Library Responsible Frame NSCFArray 2 < multiple > 64 UIKit -[UITouch(UITouchInternal) UITouch 2 < multiple > 128 GraphicsServices PurpleEventCallback Malloc 48 Bytes 2 < multiple > 96 Foundation -[NSCFArray insertObject:atIndex:] UIDelayedAction 2 < multiple > 96 UIKit -[UILongPressGestureRecognizer startTimer] NSCFArray 2 < multiple > 64 UIKit -[UILongPressGestureRecognizer touchesBegan:withEvent:] Malloc 32 Bytes 2 < multiple > 64 Foundation -[NSCFArray insertObject:atIndex:] Malloc 16 Bytes 2 < multiple > 32 Foundation -[NSCFSet unionSet:] Now I have commented out all my code in any touch event functions that I have written and it still leaks if I click on the cell a few times and then hit the back button to return to the previous view. Any ideas on what might actually be the problem here? Thanks,

• The following code to check if a file exists on a server does not work

  - by xplorer2k

  Hi Everyone, I found the following code to check if a file exists on a server, but is not working for me. It tells me that "test1.tx" does not exist even though the file exists and its size is 498 bytes. If I try with Ftp.ListDirectory it tells me that the file does not exist. If I try with Ftp.GetFileSize it does not provide any results and the debugger's immediate gives me the following message: A first chance exception of type 'System.Net.WebException' occurred in System.dll. Using "request.UseBinary = true" does not make any difference. I have posted this same question at this link: http://social.msdn.microsoft.com/Forums/en-US/ncl/thread/89e05cf3-189f-48b7-ba28-f93b1a9d44ae Could someone help me how to fix it? private void button1_Click(object sender, EventArgs e) { string ftpServerIP = txtIPaddress.Text.Trim(); string ftpUserID = txtUsername.Text.Trim(); string ftpPassword = txtPassword.Text.Trim(); try { FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpServerIP + "//tmp/test1.txt"); request.Method = WebRequestMethods.Ftp.ListDirectory; //request.Method = WebRequestMethods.Ftp.GetFileSize; request.Credentials = new NetworkCredential(ftpUserID, ftpPassword); //request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { // Okay. textBox1.AppendText(Environment.NewLine); textBox1.AppendText("File exist"); } } catch (WebException ex) { if (ex.Response != null) { FtpWebResponse response = (FtpWebResponse)ex.Response; if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable) { // Directory not found. textBox1.AppendText(Environment.NewLine); textBox1.AppendText("File does not exist"); } } } } Thanks very much, xplorer2k

Thereby telling something else to download that file. This is a pretty simple object to make, I was just curious if anyone knew how expensive this operation would be? I plan on using the command NLIST because I don't need file size information, and there will be no sub-directories in the folder. Each file in the folder will have exactly 25 characters in its name. There could be anywhere from 10 to 'maybe' a couple thousand (max around 2000) files per folder (usually on the lower end, 100-300, but currently growing). The files are anywhere from 250kb to a very VERY unlikely 10mb (usually within the 250kb to 4mb range). There possibly could be up to a few hundred folders (in which case I could change the watch frequency depending on number of folders), but currently there are only a few (6-10ish). There also would be multiple logins for the ftp server, different logins would have access to different folders. I am not asking for an implementation, just if anyone has some first or second hand knowledge about FTP, how could this affect my network. I am not opposed to putting in file retention times or change the frequency in which I check for new files.

• Drawing only part of a texture OpenGL ES iPhone

  - by Ben Reeves

  ..Continued on from my previous question I have a 320*480 RGB565 framebuffer which I wish to draw using OpenGL ES 1.0 on the iPhone. - (void)setupView { glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteriv(GL_TEXTURE_2D, GL_TEXTURE_CROP_RECT_OES, (int[4]){0, 0, 480, 320}); glEnable(GL_TEXTURE_2D); } // Updates the OpenGL view when the timer fires - (void)drawView { // Make sure that you are drawing to the current context [EAGLContext setCurrentContext:context]; //Get the 320*480 buffer const int8_t * frameBuf = [source getNextBuffer]; //Create enough storage for a 512x512 power of 2 texture int8_t lBuf[2*512*512]; memcpy (lBuf, frameBuf, 320*480*2); //Upload the texture glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 512, 512, 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, lBuf); //Draw it glDrawTexiOES(0, 0, 1, 480, 320); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } If I produce the original texture in 512*512 the output is cropped incorrectly but other than that looks fine. However using the require output size of 320*480 everything is distorted and messed up. I'm pretty sure it's the way I'm copying the framebuffer into the new 512*512 buffer. I have tried this routine int8_t lBuf[512][512][2]; const char * frameDataP = frameData; for (int ii = 0; ii < 480; ++ii) { memcpy(lBuf[ii], frameDataP, 320); frameDataP += 320; } Which is better, but the width appears to be stretched and the height is messed up. Any help appreciated.

• How can I return a value from GM_xmlhttprequest?

  - by GeoffreyF67

  I have this code here: var infiltrationResult; while(thisOption) { var trNode = document.createElement('tr'); var tdNode = document.createElement('td'); var hrefNode = document.createElement('a'); infPlanetID = thisOption.getAttribute('value'); var myURL = "http://www.hyperiums.com/servlet/Planetinf?securitylevel=90&newinfiltr=New+infiltration&planetid=" + PlanetID + "&infplanetid=" + infPlanetID; GM_xmlhttpRequest({ method: 'GET', url: myURL, headers: { 'User-agent': 'Mozilla/4.0 (compatible) Greasemonkey', 'Accept': 'application/atom+xml,application/xml,text/xml', }, onload: function(responseDetails) { if (responseDetails.responseText.match(/<b>Invalid order<\/td><\/tr><tr><td><BR><center><font color=#AAAA77 face=verdana,arial size=2>The target planet is blocking all infiltrations[\s\S]<BR><BR>/im)) { // Successful match infiltrationResult = 'Invalid Order'; } else { // Match attempt failed infiltrationResult = 'Infiltration Successfully Created'; } } }); When I add alert(infiltrationResult); right after it is assigned, I correctly see the string. However, after the function has exited, I have try the same alert and I get: undefined Any ideas what I'm doing wrong? I'm guessing it's some simple silly javascript synxtax I'm missing here :) G-Man
