  • Draw a cross at center of a UIImagePickerController.

    - by VansFannel
    Hello. I'm very new on iPhone development. I'm trying to draw a cross over the image obtained from camera. I'm using a custom ViewController that inherits from UIImagePickerController. When I star the application, I see the cross, but a few seconds after the cross disappears. Should I use cameraOverlayView? Thank you

  • Version of STL optimized for compile time?

    - by anon
    Hi! I'm looking for a variant of the STL (it's okay if it doesn't have all the functionality) that's optimized for short compile times -- I get bothered by long compile times that delay my compile-debug-edit cycle. I'm mainly interested in the containers of the STL: vector/map, and not so much the algorithms. Thanks!

  • flex builder 3 compiler won't show errors or compile specific pages

    - by Ben
    In flexbuilder 3 for some mxml files I can purposely put in syntax errors and the compiler will seem to compile the specific page(but actually not compile it) or report any errors for that page. Is there any way that you know of to get the compiler to report the errors to me so I can get it to compile the page. I've tried rebuilding all and cleaning the project already.

  • WCF cross-domain policy security error

    - by George2
    Hello everyone, I am using VSTS 2008 + C# + WCF + .Net 3.5 + Silverlight 3.0. I host Silverlight control in an html page and debug it from VSTS 2008 (press F5, then run in VSTS 2008 built-in ASP.Net development web server), then call another WCF service (hosted in another machine running IIS 7.0 + Vista). The WCF service is very simple, just return a constant string to client. When invoking the WCF service from Silverlight, I got the following error message, An error occurred while trying to make a request to URI 'https://LabTest/Test.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. Here is the clientaccesspolicy.xml file, anything wrong? <?xml version="1.0" encoding="utf-8" ?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*"> </domain> </allow-from> <grant-to> <resource path="/" include-subpaths="true"></resource> </grant-to> </policy> </cross-domain-access> </access-policy> thanks in advance, George

  • Programmatically create static arrays at compile time in C++

    - by Hippicoder
    One can define a static array at compile time as follows: const std::size_t size = 5; unsigned int list[size] = { 1, 2, 3, 4, 5 }; Question 1 - Is it possible by using various kinds of metaprogramming techniques to assign these values "programmatically" at compile time? Question 2 - Assuming all the values in the array are to be the same barr a few, is it possible to selectively assign values at compile time in a programmatic manner? eg: const std::size_t size = 7; unsigned int list[size] = { 0, 0, 2, 3, 0, 0, 0 }; Solutions using C++0x are welcome The array may be quite large, few hundred elements long The array for now will only consist of POD types It can also be assumed the size of the array will be known beforehand, in a static compile-time compliant manner. Solutions must be in C++ (no script or codegen based solutions)

  • compile a single ASP.NET (.aspx) page from the command line

    - by JoelFan
    I have a Perl script that calls aspnet_compiler.exe to compile a large ASP.NET website. The problem is that it takes very long to run. Is there any way to compile just a single .aspx file from the command line? (I think that would suit the needs of my script) It seems that all aspnet_compiler.exe can do is compile at a directory level.

  • How to compile a Windows binary in Ubuntu?

    - by George Edison
    I have a Qt application that I can compile in Ubuntu 10.04 64-bit and on Windows. However, I would like to avoid switching to Windows every time I want to compile the Windows version. Is there a way I can compile a Windows Qt executable in Ubuntu with mingw32 or something? Further, is there a way to integrate that compiler into Qt Creator?

  • does overload operator-> a compile time action?

    - by Brent
    when I tried to compile the code: struct S { void func2() {} }; class O { public: inline S* operator->() const; private: S* ses; }; inline S* O::operator->() const { return ses; } int main() { O object; object->func(); return 0; } there is a compile error reported: D:\code>g++ operatorp.cpp -S -o operatorp.exe operatorp.cpp: In function `int main()': operatorp.cpp:27: error: 'struct S' has no member named 'func' it seems that invoke the overloaded function of "operator-" is done during compile time? I'd add "-S" option for compile only.

  • What would you take into account when you were asked to compare software? [closed]

    - by mstaessen
    For my master's thesis, I am asked to make a comparative study of frameworks for cross-platform mobile development. I want to eliminate the chances of having missed something in my comparison. This is why I want to ask what YOU would value (most) when comparing such frameworks (Like for instance PhoneGap and Appcelerator Titanium). Performance, capabilities and licensing are kind of obvious, but can you think of others?

  • Straight cable or cross over cable?

    - by om sai
    I have pppoe internet connection. My ISP provides connections like this: ISP->media converter(fiber)->8 port switch(TP Link TL-SF1008D)->to individual internet connection account holders (like me) Now the connection between the media converter and the switch is done using 4 pair cross over cat5 cable and I would like to connect the cable running from the switch to the router and through router to my PC. So what type of cable should I use to make the connection between the switch and the router (straight thru cable or cross over cable)? The point I am trying to make is I am able to connect to the internet using straight through cable between the switch and my PC but when I connect the same cable between the switch and the router and from router to my PC I am not able to connect to the internet. Also, if I am using the 2 pair cable (instead of 4) between the switch and the router I am able to connect to the internet but same is not true in case of 4 pair cat5 cable.

  • Cross-match a number of worksheets to one master worksheet

    - by Carter
    Hopefully the title is not too confusing. Basically, I have a master list of addresses and those addresses are listed in multiple columns (Column A - street number, Column B - street name, Column C - street type etc) and I get a another set of addresses on a daily basis with the same address formatting. What I need to do is cross-match the daily changing list of addresses to the first list to remove any matching entries. So, for example, if the first list has 123 Main St on it, I have to ensure that there are no entries of 123 Main St on any subsequent daily lists. I'm using one address as an example but the lists contain upwards of 10000 addresses that have to be cross matched. I don't need them flagged or highlighted, just deleted from the daily lists (though if they have to be flagged or highlighted, I could work with that) Any help here would be much appreciated.

  • How to compile gcc-4.0 on Mountain Lion

    - by Frizlab
    So far I've successfully launched the configure, but when I type make, I get the following error, after some time (there's a lot which compile successfully): ld: unknown/unsupported architecture name for: -arch i686 /usr/bin/libtool: internal link edit command failed make[2]: *** [libgcc_s.dylib] Error 1 make[1]: *** [libgcc.a] Error 2 make: *** [all-gcc] Error 2 Is there a way to tell gcc not to compile itself for the i686 architecture?

  • How do I install a newer version of GTK in Ubuntu without replacing the current one?

    - by William Friesen
    I am trying to compile file-roller from git, but running autogen.sh gives me this error configure: error: Package requirements (gtk+-3.0 >= 2.91.1) were not met: No package 'gtk+-3.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GTK_CFLAGS and GTK_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. I am running Ubuntu Maverick and don't wish to completely replace my current version of gtk, glib, etc. I have tried to compile GTK using the --prefix argument of autogen.sh, but this gives me a similar error about my version of glib. How can I successfully compile file-roller using these new libraries without borking my install?

  • What's the best way to do cross browser testing?

    - by Doug
    What's the best way for me to check if my website is compatible in IE7,8, Safari, FF, and Chrome without having to install each and everyone? I mainly want to check the CSS, HTML, and JavaScript. Update I put a bounty in hopes there is a more practical solution for someone like myself. I am using Windows 7 Home Premium x64. Update2 I don't mind installing these browsers now, but I can't even if I wanted to. Windows 7 doesn't allow me to install IE7.

  • Which cross threading invoke function is better for a control that is inherited?

    - by Stevoni
    I have a relatively simple question regarding the best way to call the DataGridView.Rows.Add function when it is inherited into the current control. Which is the best way to make the call to the inherited control? Call it directly in the invoke or call it using recursive-like function? They both seem to produce the same result, a row gets added and the quantity is returned, but which is the most efficient? The delegate: Private Delegate Function ReturnDelegate() As Object The two ways are: A) Private Overloads Function AddRow() As Integer If InvokeRequired Then Return CInt(Invoke(New ReturnDelegate(AddressOf AddRow))) Else Return Rows.Add() End If End Function Or B) Private Function RowsAdd() As Integer If Me.InvokeRequired Then Return CInt(Me.Invoke(New ReturnDelegate(AddressOf MyBase.Rows.Add))) Else Return MyBase.Rows.Add End If End Function

  • Can you cross-site ping another site using C# or JS/Ajax?

    - by Josh Harris
    On our web application I am trying to ping a 3rd party site to see if it is up before redirecting our customers to it. So far I have not seen a way to do this other than from a desktop app or system console. Is this possible? I have heard that there was an image trick in original ASP. Currently we are using .NET MVC with Javascript. Thank you, Josh

  • How to deal with forward declaration / #import in Cocoa Touch (Objective-C cross C++) correctly?

    - by unknownthreat
    I am trying to write this header file: //@class AQPlayer; //#import "AQPlayer.h" @interface AQ_PWN_iPhoneViewController : UIViewController { AQPlayer* player; } @end AQPlayer is a .mm file written in C++. I tried to make a class forward declaration here, but it complains to me: error: cannot find interface declaration for 'AQPlayer' So I tried to "#import" the header file instead, but it complains something completely off and weird. Here's a slice of the error complained: In file included from /Users/akaraphan/Desktop/SpecialTopic1/AQ_PWN_iPhone/Classes/AQPlayer.h:51, from /Users/akaraphan/Desktop/SpecialTopic1/AQ_PWN_iPhone/Classes/AQ_PWN_iPhoneViewController.h:12, from /Users/akaraphan/Desktop/SpecialTopic1/AQ_PWN_iPhone/Classes/AQ_PWN_iPhoneAppDelegate.m:10: /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:78: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'CAStreamBasicDescription' /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:230: error: expected '=', ',', ';', 'asm' or '__attribute__' before '<' token /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:231: error: expected '=', ',', ';', 'asm' or '__attribute__' before '==' token /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:233: error: expected '=', ',', ';', 'asm' or '__attribute__' before '!=' token /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:234: error: expected '=', ',', ';', 'asm' or '__attribute__' before '<=' token /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:235: error: expected '=', ',', ';', 'asm' or '__attribute__' before '>=' token /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:236: error: expected '=', ',', ';', 'asm' or '__attribute__' before '>' token /Developer/Examples/CoreAudio/PublicUtility/CAStreamBasicDescription.h:239: error: expected ';', ',' or ')' before '&' token Am I missing something?

  • What's the cross-browser way to capture all single clicks on a button?

    - by sany
    What's the best way to execute a function exactly once every time a button is clicked, regardless of click speed and browser? Simply binding a "click" handler works perfectly in all browsers except IE. In IE, when the user clicks too fast, only "dblclick" fires, so the "click" handler is never executed. Other browsers trigger both events so it's not a problem for them. The obvious solution/hack (to me at least) is to attach a dblclick handler in IE that triggers my click handler twice. Another idea is to track clicks myself with mousedown/mouseup, which seems pretty primitive and probably belongs in a framework rather than my application. So, what's the best/usual/right way of handling this? (pure javascript or jQuery preferred)
