  • Just-in-time invocation of Facebook login window from UIWebView

    - by Chris Garrett
    I have an app that presents a UIWebView pointing to my own server. I have a Facebook Like button on some pages inside the UIWebView. I have it working now, but the login screen is way too big for the phone screen. I would like to present a nicer login dialog such as the one in the Facebook iPhone API, and then continue back to the web view. The Facebook iPhone SDK has support for a login button and iPhone-friendly login screen, but it assumes that a user will click a login button before doing anything Facebook related. I would like the Like button to just appear, and to bring up the iPhone login screen only when necessary. I have monitored HTTP requests from my web view, and it looks like I could intercept the login request there, and present the login dialog. However, it seems that this would be fragile, because if Facebook changes those calls then my app will no longer work. Is there a more elegant way to do this?

  • Programatically detect number of physical processors/cores or if hyper-threading is active on Window

    - by HTASSCPP
    I have a multithreaded c++ application that runs on Windows, Mac and a few Linux flavours. To make a long story short: Inorder for it to run at maximum efficiency I have to be able to instantiate a single thread per physical processor/core. Creating more threads than there are physical processors/cores degrades the performance of my program considerably. I can already correctly detect the number of logical processors/cores correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyper-treading is supported AND active. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED? If so, how exactly.

  • compile AMR-nb codec with RVCT for WinCE/Window Mobile

    - by pps
    Hello everybody, I'm working on amr speech codec (porting/optimization) I have an arm (for WinCE) optimized version from voiceage and I use it as a reference in performance testing. So far, binary produced with my lib beats the other one by around 20-30%! I use Vs2008 and I have limited access to ARM instruction set I can generate with Microsoft compiler. So I tried to look for alternative compiler to see what would be performance difference. I have RVCT compiler, but it produces elf binaries/object files. However, I run my test on a wince mobile phone (TyTn 2) so I need to find a way to run code compiled with RVCT on WinCE. Some of the options are 1) to produce assembly listing (-S option of armcc), and try to assemble with some other assembler that can create COFF (MS assembler for arm) 2) compile and convert generated ELF object file to COFF object (seems like objcopy of gnu binutils could help me with that) 3) using fromelf utility supplied by RVCT create BIN file and somehow try to mangle the bits so I can execute them ;) My first attempt is to create a simple c++ file with one exported function, compile it with RVCT and then try to run that function on the smartphone. The emitted assembly cannot be assembled by the ms assembler (not only they are not compatible, but also ms assembler rejects some of the instructions generated with RVCT compiler; ASR opcode in my case) Then I tried to convert ELF object to coff format and I can't find any information on that. There is a gcc port for ce and objcopy from that toolset is supposed to be able to do the task. However, I can't get it working. I tried different switches, but I have no idea what exactly I need to specify as bfdname for input and output format. So, I couldn't get it working either. Dumping with fromelf and using generated bin file seems to be overkill, so I decided to ask you guys if there is anything I should try to do or maybe someone has already done similar task and could help me. Basically, all I want to do is to compile my code with RVCT compiler and see what's the performance difference. My code has zero dependencies on any c runtime functions. thanks!

  • javascript eval backslash in window NT path problem

    - by Hammad Tariq
    I am experiencing a classic JS case (in my opinion) but after a lot of googling, still not able to find a solution. Backslash is considered as a escape character in JS but what you need when you need to pass windows path from the JS and print it? I am using eval because my java applet is executing the code and placing bits when it has a string to evaluate. That's why eval is necessary, however I have made an example which is below: <div id="mainTabs"></div> <script> var s = "document.getElementById('mainTabs').innerHTML='\\C\ganye\file.doc'"; eval(s); </script> I tried double backslashes, not working, if anyone could help me get around this with as less hassle as possible, I will feel grateful.

  • Open a new browser window, or set focus to an existing browser

    - by Craig Myles
    Hi, I'm using code similar to the following: http://blog.flexexamples.com/2007/08/29/launching-new-browser-windows-from-flex/ I have a Flex app running in AIR, and when I click on a URL it opens a new tab in my existing browser. In addition to this the focus doesn't set to the browser. What this means is that I'm not aware of the URL opening in the browser unless I actually change focus from the app to the browser. Is it possible to open a brand new spanking browser, or change focus to the browser so its really obvious to the user? Thanks.

  • Visual Studio expression containing a term named "by" cannot be evaluated in the watch window

    - by Andrei Pana
    Consider my C++ code below: int _tmain(int argc, _TCHAR* argv[]) { int by = 10; printf("%d\n", by); int bx = 20; printf("%d\n", (by + bx)); return 0; } which works fine. The funny thing is with the "by" variable. If I try to add a watch for a simple expression that contains by, the result will be CXX0030: Error: expression cannot be evaluated. For example, on a breakpoint on return 0, if I add the following watches I get the results mentioned: by : 10 bx : 20 by + 5 : CXX0030: Error: expression cannot be evaluated bx + 5 : 25 by + bx : CXX0030: Error: expression cannot be evaluated (by) + bx : 30 by + (bx) : CXX0030: Error: expression cannot be evaluated bx + (by) : CXX0014: Error: missing operrand This happens on VS2010, VS2008 on multiple computers. So, more out of curiosity, what is happening with "by"? Is it some kind of strange operator? Why doesn't bx get the same treatment? (I've tried google on this but it is quite difficult to get some relevant hits with terms like "by")

  • Installshield 2009 Premier Basic MSI: Not show a warning message window during uninstall

    - by Samir
    Installshield 2009 Premier Basic MSI: When I uninstall there is a Message Box saying that explorer has to be closed: [Title] My-Product-Name [List] Explorer [radio button 1, Selected by default] Automatically close applications and attempt to restart them after setup is complete [radio button 2] Do not close applications. (A Reboot will be required) [Ok Button] [Cancel Button] If I click OK [with radio button 1 selected] all opened folders are closed !!! How to get rid of this, I don't want any warning message box to show and not close explorer either? More info: I have a dll which is used to show explorer context menu with icons when we right click on any file/folder. This dll is registered during installation and unregistered during uninstall. When we uninstall WinRAR we don't see any such messages, do we?

  • Using Java to retrieve the CPU Usage for Window's Processes

    - by stjowa
    Hello all, I am looking for a Java solution to finding the CPU usage for a running process in Windows. After looking around the web, there seems to be little information on a solution in Java. Keep in mind, I am not looking to find the CPU usage for the JVM, but any process running in Windows at the time. I am able to retrieve the memory usage in Java by using the exec("tasklist.exe ... ") to retrieve and parse process information. Although there is an aggregate CPU cycle timer for each process, I do not see a CPU usage column. Any help would be greatly appreciated. Also, if possible, I would like to stay away from C libraries; however, if there is no other alternative, a solution by that means would be appropriate. Thanks a lot, Steve

  • Window Media Player issues two requests for the audio on web page

    - by Ron Harlev
    I'm using Windows Media Player in a web page. I have version 11 installed so that is the version I'm testing with right now. The player is embedded on the page with this HTML: <OBJECT id='MS_mediaPlayer' width="400" height="45" classid='CLSID:6BF52A52-394A-11D3-B153-00C04F79FAA6' codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701' standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject'> <param name='autoStart' value="false"> <param name='uiMode' value="invisible"> <param name='loop' value="false"> </OBJECT> I'm calling in JavaScript: MS_mediaPlayer.URL = "SomeAudioFile.mp3" MS_mediaPlayer.controls.play(); When I look at Fiddler I can see that the player actually downloads "SomeAudioFile.mp3" twice. Is there some setting I have wrong? I was trying to set the "autoPlay" to true and avoid calling "play()". Got the same result - two downloads. UPDATE: The first request's user-agent is "Windows-Media-Player/11.0.5721.5268". The second has "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; GTB6; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)". Looks like the browser is running the same request the second time. No Idea why Any ideas? UPDATE (4/1/10): Still no solution. I debugged the JS thoroughly and there is only one call to MediaPlayer.URL='.....' to set the audio file. Nothing else triggers the media player to load the file and there is no other place referencing the audio file on the page. One other interesting fact is that this doesn't happen (the double loading of the audio) when I run the browser locally on my development web server. But other remote requests to the same web server generate the double audio loading. I believe I eliminated any correlation with specific IE version or media player version. This happens with IE6-8 and WM9-12

  • Creating a tool dockable window for visual studio

    - by Morgeh
    So I have a web service system for mananging development projects, what I would like to do is create a visual studio plugin that accesses the web service and returns a list of tasks for the current users (via some sort of login). Looking round the internet I can't find any good examples or tutorials on how to create a visual studio plugin that can be docked to the bottom of the screen (same place as error list, test results, etc) Does anyone know of a good website I can look at for examples or tutorials of the basics of creating a visual studio plugin, specifically for VS2008?

  • Window Installer custom action BEFORE any validation

    - by Marc
    I wrote a Windows Installer custom action based on the tutorial found here: http://www.codeproject.com/kb/install/msicustomaction.aspx My custom action is killing a background process of a given name which could still be opened by the user. The reason is that I don't want users to see the warning that a given EXE is running and must be closed so that setup can continue. This works fine when the MSI passes through the UI sequence as the action is created in "InstallUISequence" table like in the tutorial. However, when the MSI is used silently (right-click and select repair or uninstall), then my custom action isn't executed of course. Where do I have to put my custom action so that it is executed immediately also when run silently? I tried adding it to "InstallExecuteSequence", but the 'app running' warning is still shown. I then tried lowering the sequence number of my custom action to 5, but this also didn't help. Note: I'm using Orca to modify an MSI generated from a Visual Studio setup project. I'm then using the transform file to apply it.

  • using alias parameters in window command prompt

    - by freshWoWer
    Source:http://jpsoft.com/help/index.htm?alias.htm Aliases can use command line parameters or parameters like those in batch files. The command line parameters are numbered from %0 to %511. (%0 contains the alias name.) For example, the following alias will change directories, perform a command, and return to the original directory: alias in pushd %1 & %2$ & popd when i run the above, my command prompt gives error saying %1 * Unable to read value of alias * '%2' is not recognized as an internal or external command, operable program or batch file. 'popd`' is not recognized as an internal or external command, operable program or batch file. if you use double quote instead, alias in "pushd %1 & dir & popd" it doesn't interprets the %1 when you execute the alias C:\abc\defalias Dumping all defined aliases for CMD.EXE. in =pushd %1 & dir & popd alias def wont work ---------EDIT------------ let me try some sample output with a simple echo alias D:\abc\defalias /? Usage: ALIAS [-v] [-p programName] [-f filespec] [ ] [-v] means verbose output. [-d] means delete aliases. [-p programName] specifies which image file name these alias definitions are for. Default is CMD.EXE [-f filespec] specifies a file which contains the alises. C:\Office\dev15alias out 'echo %1' %1' * Unable to read value of alias * C:\Office\dev15alias out backtick echo %1 backtick %1` * Unable to read value of alias * C:\Office\dev15alias out "echo %1" C:\Office\dev15alias Dumping all defined aliases for CMD.EXE. out =echo %1 C:\Office\dev15out abc %1 C:\Office\dev15alias out echo %1 %1 * Unable to read value of alias * C:\Office\dev15out abc ECHO is on. Problem is, both single quote and back tick produces error, while double quote wont treat %1 as variable parameter

  • Detecting death of spawned process using Window CRT

    - by Michael Tiller
    Executive summary: I need a way to determine whether a Windows process I've spawned via _spawnl and am communicating with using FDs from _pipe has died. Details: I'm using the low-level CRT function in Windows (_eof, _read) to communicate with a process that was spawned via a call to _spawnl (with the P_NOWAIT) flag. I'm using _pipe to create file descriptors to communicate with this spawned process and passing those descriptors (the FD #) to it on the command line. It is worth mentioning that I don't control the spawned process. It's a black box to me. It turns out that the process we are spawning occasionally crashes. I'm trying to make my code robust to this by detecting the crash. Unfortunately, I can't see a way to do this. It seems reasonable to me to expect that a call to _eof or _read on one of those descriptors would return an error status (-1) if the process had died. Unfortunately, that isn't the case. It appears that the descriptors have a life of their own independent of the spawned process. So even though the process on the other end is dead, I get no error status on the file descriptor I'm using to communicate with it. I've got the PID for the nested process (returned from the _spanwnl call) but I don't see anything I can do with that. My code works really well except for one thing. I can't detect whether the spawned process is simply busy computing me an answer or has died. If I can use the information from _pipe and _spawnl to determine if the spawned process is dead, I'll be golden. Suggestions very welcome. Thanks in advance. UPDATE: I found a fairly simple solution and added it as the selected answer.

  • Javascript running in facebox window

    - by Rudiger
    I'm modifying a website to have a pop up box appear when a user rates something prompting the user to login. Unfortunately the login process is something that I don't control and it uses a whole heap of javascript and redirects to do it and it seems that the javascript is failing. Can javascript run in the modal box or is there a way around this?

  • Problem with urllib

  • Flashing window in gnu screen

    - by gotts
    I really like gnu screen but there is a problem in my environment when I use it. Examle: username@domain:/var/www$ l Display all 130 possibilities? (y or n) when you click [Tab] to perform autocompletion there is a screen flashing for a very short period of time(looks like white screen but I can see it for a very-very short time). There isn't any problems with that when I execute the same action in normal/non-screen environment. This is what my .screenrc looks like: attrcolor b ".I" termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm' defbce "on" term screen-256color-bce
