  • iPhone 4.0 on iPhone but still Ad-Hoc compile for 3.1.3?

    - by Mark
    Device: Version : 3.1 Build: 3511 Device: iPhone OS: iPhone OS 4.0 xCode 3.2.2 (Old) xCode 3.2.3 (New; For iPhone 4.0 Beta) Background: As you can see I installed 4.0 on my iPhone as I read on this forum it's really hard to near impossible to downgrade back to 3.1.3, but it's my only device I have and use for development. When I try to continue to develop and build with the old xCode it tells me that "No provisioned iPhone OS device is connected". When I select Simulator it does compile and build, however when I spread this file it does not work on the devices of my testers, they get a Signed error. When I run the new xCode, it does compile and build on the Device and when I spread this file, it does work on the devices of my testers (which are running the current official version 3.1.3). Questions: Why is there a difference between building for Simulator and Device? A simulator build never seem to work on the devices of my testers because of signing issues and the build for device does work. Currently it seems the old xCode became useless, however I read that you may not use the Beta xCode to build your application for release. So knowing the above how am I able to pull this off with my current setup due the fact the old xCode won't let me build properly.

  • Good way to capture/replay sessions from Apache Log?

    - by Mark Harrison
    For performance testing, I would like to capture some traffic from a production server and use that as a basis to replay the request to a test server in order to simulate a realistic load in our development environment. These are all stateless queries, so no issues regarding cookies, sessions, etc. The Apache log timestamps everything down to a 1 second resolution, but that's not fine enough granularity for our peak times. What's the best way to capture more fine-grained timestamps for replay? And is there some ab-like load generating program that can use this data to replicate load?

  • cvs to mercurial conversion gets tags wrong

    - by Mark Borgerding
    I've tried all the recommended conversion techniques Mostly they manage to get the latest version of the files right, but every one of them trashes my history. Many (most?) of the tags from my cvs project have at least one file in error when I run "hg up $tag" My cvs repo is not all that complicated. Why can't anything convert it? I'd like to dump cvs and convert to mercurial, but not without history. To recap my frustration: I tried hg convert (tried --branchsort,--timesort, fuzz=0) I tried cvs2svn and then hg convert. tailor does not work with recent versions of mercurial fromcvs disappeared from the face of the earth hg-cvs-import has been abandoned for 4 years and doesn't work with recent versions of hg I have tried using the two most recent versions of mercurial ( 1.5 and 1.5.1 ).

  • Repeated properties design pattern

    - by Mark
    I have a DownloadManager class that manages multiple DownloadItem objects. Each DownloadItem has events like ProgressChanged and DownloadCompleted. Usually you want to use the same event handler for all download items, so it's a bit annoying to have to set the event handlers over and over again for each DownloadItem. Thus, I need to decide which pattern to use: Use one DownloadItem as a template and clone it as necessary var dm = DownloadManager(); var di = DownloadItem(); di.ProgressChanged += new DownloadProgressChangedEventHandler(di_ProgressChanged); di.DownloadCompleted += new DownloadProgressChangedEventHandler(di_DownloadCompleted); DownloadItem newDi; newDi = di.Clone(); newDi.Uri = "http://google.com"; dm.Enqueue(newDi); newDi = di.Clone(); newDi.Uri = "http://yahoo.com"; dm.Enqueue(newDi); Set the event handlers on the DownloadManager instead and have it copy the events over to each DownloadItem that is enqeued. var dm = DownloadManager(); dm.ProgressChanged += new DownloadProgressChangedEventHandler(di_ProgressChanged); dm.DownloadCompleted += new DownloadProgressChangedEventHandler(di_DownloadCompleted); dm.Enqueue(new DownloadItem("http://google.com")); dm.Enqueue(new DownloadItem("http://yahoo.com")); Or use some kind of factory var dm = DownloadManager(); var dif = DownloadItemFactory(); dif.ProgressChanged += new DownloadProgressChangedEventHandler(di_ProgressChanged); dif.DownloadCompleted += new DownloadProgressChangedEventHandler(di_DownloadCompleted); dm.Enqueue(dif.Create("http://google.com")); dm.Enqueue(dif.Create("http://yahoo.com")); What would you recommend?

  • Java: matching two different type of array

    - by sling
    Hi, I am doing a password login that requires me to match two array: User and Pass. If user key in "mark" and "pass", it should show successfully. However I have trouble with the String[] input = pass.getPassword(); and the matching of the two arrays. String[] User = {"mark", "susan", "bobo"}; String[] Pass = {"pass", "word", "password"}; String[] input = pass.getPassword(); if(Pass.length == input.length && user.getText().equals(User)) { lblstat.setForeground(Color.GREEN); lblstat.setText("Successful"); } else { lblstat.setForeground(Color.RED); lblstat.setText("Failed"); }

  • Looking for streaming xml pretty printer in C/C++ using expat or libxml2

    - by Mark Zeren
    I'm looking for a streaming xml pretty printer for C/C++ that's either self contained or that uses libxml2 or expat. I've searched a bit and not found one. It seems like something that would be generally useful. Am I missing an obvious tool that does this? Background: I have a library that outputs xml without whitespace all on one line. In some cases I'd like to pretty print that output. I'm looking for a BSD-ish licensed C/C++ library or sample code that will take a raw xml byte stream and pretty print it. Here's some pseudo code showing one way that I might use this functionality: void my_write(const char* buf, int len); PrettyPrinter pp(bind(&my_write)); while (...) { // ... get some more xml ... const char* buf = xmlSource.get_buf(); int len = xmlSource.get_buf_len(); int written = pp.write(buf, len); // calls my_write with pretty printed xml // ... error handling, maybe call write again, etc. ... } I'd like to avoid instantiating a DOM representation. I already have dependencies on the expat and libxml2 shared libraries, and I'd rather not add any more shared library dependencies.

  • php adding images to another image, exact positioning

    - by user271619
    I have a cool snippet of code that works well, except one thing. The code will take an icon I want to add to an existing picture. I can position it where I want too! Which is exactly what I need to do. However, I'm stuck on one thing, concerning the placement. The code "starting position" (on the main image: navIcons.png) is from the Bottom Right. I have 2 variables: $move_left = 10; & $move_up = 8;. So, the means I can position the icon.png 10px left, and 8px up, from the bottom right corner. I really really want to start the positioning from the Top Left of the image, so I'm really moving the icon 10px right & 8px down, from the top left position of the main image. Can someone look at my code and see if I'm just missing something that inverts that starting position? function attachIcon($imgname) { $mark = imagecreatefrompng($imgname); imagesavealpha($mark, true); list($icon_width, $icon_height) = getimagesize($imgname); $img = imagecreatefrompng('images/sprites/navIcons.png'); imagesavealpha($img, true); $move_left = 10; $move_up = 9; list($mainpic_width, $mainpic_height) = getimagesize('images/sprites/navIcons.png'); imagecopy($img, $mark, $mainpic_width-$icon_width-$move_left, $mainpic_height-$icon_height-$move_up, 0, 0, $icon_width, $icon_height); imagepng($img); // display the image + positioned icon in the browser //imagepng($img,'newnavIcon.png'); // rewrite the image with icon attached. } header('Content-Type: image/png'); attachIcon('icon.png'); ? For those who are wondering why I'd even bother doing this. In a nutshell, I like to add 16x16 icons to 1 single image, while using css to display that individual icon. This does involve me downloading the image (sprite) and open photoshop, add the new icon (positioning it), and reuploading it to the server. Not a massive ordeal, but just having fun with php.

  • Automatically charge PayPal account?

    - by Mark
    I'd like to automatically charge my members a variable amount of money based on the services they use on my website. They would accumulate a balance owing, and then every week they would be charged for that amount. Is there a way I can do this without having to store their credit card information in my database? (Similar to my last question, but I just realized I don't really want to go through the headaches and liability issues of having to safely store CC info)

  • IIS and Flash forceSmoothing issue

    - by Mark Kennerley
    Hi everyone, I am incorporating a Flash Flickr Polaroid file into my site, http://www.no3dfx.com/polaroid/ But I am having problems with the images being smooth. I have edited the code throughout with forceSmoothing = true and _quality = best. It all works and looks smooth if I test the file in the preview window and if I run the HTML file. But as soon as I put the file under IIS the smoothing stops. All my flash players are v10+ I have turned the IIS compression off but no luck. Can anyone please help with this? Thanks, Clyde

  • Best ways to collaborate with small number of people

    - by Mark Szymanski
    Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!

  • Can the behaviour of new HTML5 form types be overridden?

    - by Mark Perkins
    I was wondering if anyone knew if it were possible to override the default behaviour of browsers that support the new HTML input types such as type="email" and type="date"? I appreciate that I could test if a browser supports an input type and provide a fallback for those browsers that don't, but what I want to know is is there any way to prevent that default behaviour from happening in browsers that do support it? For instance, if in Opera I want to use the date input type, but I don't want Opera to display the native datepicker (i.e. I want to replace it with my own custom one) is that possible? Are there any DOM events triggered like onDatePickerShow that one can hook into? I don't believe that this is possible, but if anyone knows for sure one way or the other I would love to hear from you.

  • ASP.NET Gridview Checkbox value to DataTable

    - by Mark
    Hey all, First off, im using a checkbox to highlight a true or false value from a dataset which I want to be able to change it. Unfortunately databinding the DataTable to the GridView checkboxes doesnt work (as you probably know) as it requires it to be in "edit" mode. The way I've gotten round this is having the checkbox reading the data table value seperately rather than being databound and locked: Checked='<%# Convert.ToBoolean(Eval("myValue")) %>' So that solves checkbox values from DataTable - GridView, now I need to do the opposite having the changed checkbox values go from GridView - DataTable as it is not ready to submit it to my data source (SQL) just yet. I figure I need to run a loop through the GridView rows, thats a give'un, what I can't figure out is how to replace/update just a single value in a row of a DataTable , only the ability to add or remove an entire row by the looks of things (something I don't want to do). So can anyone offer a workaround? Or is there a way to have a databound but always editable checkbox in a gridview?

  • Browser security when calling HTTP assets via a SWF on a HTTPS site

    - by Mark Ursino
    We have a site that runs on HTTPS and needs to pull in various JS assets to run a video player on the page. We get a browser security warning on this page because the JS files we are externally calling are being accessed via HTTP, not HTTPS. E.g. // HTTP reference on a HTTPS site <script src="http://the-cdn.tld/player.js"></script> Simply accessing this one JS assets via HTTP and not HTTPS will cause the browser security warning which we need to get rid of. The provider of the JS file does not support an HTTPS equivalent (like Google Analytics does). We would ideally love to just do the following, but the provider does not have this: // HTTPS reference on a HTTPS site <script src="https://the-cdn.tld/player.js"></script> One option we had was to just download a copy of the JS file and serve it on the HTTPS site, however we have concerns with this as it is not recommended by the provider and will not include updates from them. Assuming we cannot do that, we were thinking a possible other option would be to use a SWF file as a proxy. We were thinking that we could have one of our flash guys create a SWF that loads in the HTTP-served JS file to the page. We were wondering that if this SWF makes the request, would that prevent the browser from showing the security warning or not? I assumed that we would still see the warning since the SWF is still making the request through the browser, but I wanted to see what the hive mind thinks.

  • Workaround for basic syntax not being parsed.

    - by Mark Tomlin
    I want to have a class property that allow for an expression to take place on the right side of the equals sign. All versions of PHP choke on the following code, but it is written in this way to allow for easier extendibility in the future. /* Example SDK Class */ class SDK { /* Runtime Option Flags */ // Strings # 0: Makes no change to the strings. var $STRING_NONE = (1 << 0); # 1: Removes color codes from the string. var $STRING_STRIP_COLOR = (1 << 1); # 2: Removes language codes from the string. var $STRING_STRIP_LANG = (1 << 2); # 3: Removes all formatting from the string. var $STRING_STRIP = SELF::STRING_STRIP_COLOR & SELF::STRING_STRIP_LANG; # 4: Converts color codes to HTML & UTF-8. var $STRING_HTML = (1 << 3); # 8: Converts color codes to ECMA-48 escape color codes & UTF-8. var $STRING_CONSOLE = (1 << 4); # 16: Changes player names only. var $STRING_NAMES = (1 << 5); # 32: Changes host names only. var $STRING_HOSTS = (1 << 6); function SDK($fString = SELF::STRING_HTML & SELF::STRING_NAMES & SELF_HOST) { // constructor code. } } $SDK &= new SDK(SDK::STRING_NONE); (1 << 0) seems like very basic syntax to me, and is not fathomable why PHP would not allow for such a thing. Can anyone think of a work around that would maintain readability and future expandability of the following code?

  • Replace in place, parsing & string manipulation.

    - by Mark Tomlin
    I'm trying to replace a set of characters within a string. The string may or may not have any data to change. The string is marked up in a way that allows for it to change it's color from a set of characters. The string can reset it's it's formatting to default by using a defined set of characters. This setup is very much like the ECMA-48 standard used on LINUX consoles for colors and other special effects. Where one string could be ^0Black^1Red^2Green^3Yellow^4Blue^5Purple^6Cyan^7White Producing the following HTML: <span style="color: #000">Black</span><span style="color: #F00">Red</span><span style="color: #0F0">Green</span><span style="color: #FF0">Yellow</span><span style="color: #00F">Blue</span><span style="color: #F0F">Purple</span><span style="color: #0FF">Cyan</span><span style="color: #FFF">White</span> Another string (^1Error^8: ^3User Error) could also produce: <span style="color: #F00">Error</span>: <span style="color: #FF0">User Error</span> You might of noticed the ^8 part of that string resets the color for that part of the string. What's the best way to go about parsing these kinds of strings?

  • How often do you find javascript disabled on browsers?

    - by Mark Redman
    I have started using ajax/jQuery in our websites / application. There are many plugins that support degrading the javascript to browsers that dont have javascript enabled and techniques to support this. What are peoples thoughts on javascript support, we build applications rather than just websites and are looking to just support javascript enabled browsers as a pre-requisite assuming that most people or companies have javascript enabled. Do you find most people have javascript? do you monitor the percentage of javascript/non-javascript browsers (I guess this can be done with website stats) and what are the numbers regarding this?

I want to make a text box that is colored magenta with black text, but cannot get the text to be black. text(x, y, 'Summary', backgroundcolor = 'm', color = 'k') This gives me a magenta background and then text that is almost just as pink. Any ideas what I'm doing wrong? Many thanks!

  • How fast can you make linear search?

    - by Mark Probst
    I'm looking to optimize this linear search: static int linear (const int *arr, int n, int key) { int i = 0; while (i < n) { if (arr [i] >= key) break; ++i; } return i; } The array is sorted and the function is supposed to return the index of the first element that is greater or equal to the key. They array is not large (below 200 elements) and will be prepared once for a large number of searches. Array elements after the n-th can if necessary be initialized to something appropriate, if that speeds up the search. No, binary search is not allowed, only linear search.

  • Sorting Arrays by More the One Value, and Prioritizing the Sort based on Column data.

    - by Mark Tomlin
    I'm looking for a way to sort an array, based on the information in each row, based on the information in certain cells, that I'll call columns. Each row has columns that must be sorted based on the priority of: timetime, lapcount & timestamp. Each column cotains this information: split1, split2, split3, laptime, lapcount, timestamp. laptime if in hundredths of a second. (1:23.45 or 1 Minute, 23 Seconds & 45 Hundredths is 8345.) Lapcount is a simple unsigned tiny int, or unsigned char. timestamp is unix epoch. The lowest laptime should be at the get a better standing in this sort. Should two peoples laptimes equal, then timestamp will be used to give the better standing in this sort. Should two peoples timestamp equal, then the person with less of a lapcount get's the better standing in this sort. By better standing, I mean closer to the top of the array, closer to the index of zero where it a numerical array. I think the array sorting functions built into php can do this with a callback, I was wondering what the best approch was for a weighted sort like this would be.
