• Cross Domain Cookies Problem (ASP.NET)

  - by Laserson

  Hi guys, i have a problem with cross-domain cookies. I read a lot of documentation about sharing cookies between subdomains. The main idea of all articles is set Domain property to something like ".mydomain.com". I've created two domains on local IIS server - test1.local.boo and test2.local.boo. They works great and visible with browser. I have the following code: Site test1 - Writes cookie: HttpCookie myCookie = new HttpCookie("TestCookie"); myCookie.Domain = ".local.boo"; myCookie["msg"] = "Welcome from Cookie"; Response.Cookies.Add(myCookie); Site test2 - Reads cookie: HttpCookie cookie = Request.Cookies["TestCookie"]; if (cookie != null) { Response.Write(cookie["msg"]); } else { Response.Write("FAILED"); } This code always shows FAILED message. So it means that second site can't read cookie from the same subdomain. Where is my mistake??

• Game Objects Talking To Each Other

  - by PhilCK

  What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the size of projects I was doing. However my projects have been getting bigger in size and complexity and now I want to start re-using code, and making my head a simpler place. The main problem I have is generally along the lines of Player needs to know about the Map and so does the Enemy, this has usually descended into setting lots of pointers and having lots of dependencies, and this becomes a mess quickly. I have thought along the lines of a message style system. but I cant really see how this reduces the dependencies, as I would still be sending the pointers everywhere. Thanks. PS: I guess this has been discussed before, but I don't know what its called just the need I have.

• embedded dev. question - how to break free from a faulty serial port opening?

  - by user347266

  Under WindowsCE, C++ project, I'm trying to work with devices connected via both "real" serial ports and/or serial-to-usb wrappers ("virtual" serial ports); my problem is - when I try to open the port, if something goes wrong, the function never returns and the system goes into some non-responsive state and has to be eventually rebooted. I need to open the ports from the main thread. The question is - how can I make it happen in a controlled way?? this is the opening code snippet: std::ostringstream device_name; device_name << "\\.\COM" << port; m_port = ::CreateFile(device_name.str().c_str(), GENERIC_READ | GENERIC_WRITE, 0, // exclusive access NULL, // no security OPEN_EXISTING, FILE_FLAG_OVERLAPPED, // overlapped I/O NULL); // null template any suggestions would be greatly appreciated thanks!

• Problem while compiling the code

  - by Atul

  Can someone points me the problem in the code when compiled with gcc 4.1.0. #define X 10 int main() { double a = 1e-X; return 0; } I am getting error:Exponent has no digits. When i replace X with 10, it works fine. Also i checked with g++ -E command to see the file with preprocessors applied, it has not replaced X with 10. I was under the impression that preprocessor replaces every macro defined in the file with the replacement text with applying any intelligence. Am I wrong? I know this is a really silly question but I am confused and I would rather be silly than confused :). Any comments/suggestions.

• Twisted Matrix and telnet server implementation

  - by ypercube

  I have a project which is essentially a game server where users connect and send text commands via telnet. The code is in C and really old and unmodular and has several bugs and missing features. The main function alone is half the code. I came to the conclusion that rewriting it in TwistedMachine could actually result in faster completement, besides other benefits. So, here is the questions: What packages and modules I should use? I see a "telnet" module inside "protocols" package. I also see "cronch" package with "ssh" and another "telnet" module. I'm a complete novice regarding Python.

• Pass, edit and return variable in C

  - by Supertecnoboff

  I am new to C programming and recently I have been playing around with functions in C programming. But I have a simple problem: Basically I want to pass an integer to a function, have the function edit it and then pass back the integer to the main function. I am working on this but it isn't working..... Here is my code: int update_SEG_values(int DIGIT_1, int DIGIT_2) { // How many tens in the "TEMP_COUNT". DIGIT_2 = ((TEMP_COUNT) / 10); // How much is left for us to display. TEMP_COUNT = TEMP_COUNT - ((DIGIT_2) * 10); // How many ones. DIGIT_1 = ((TEMP_COUNT) / 1); return(DIGIT_1, DIGIT_2); } What am I doing wrong here?

• Jquery to slide on load

  I have a simple slider that works on click. How can I automate it so it runs automatically yet keeping the click function as it is? $(document).ready(function() { var currentPosition = 0; var slideHeight = 360; var slides = $('.main-item'); var numberOfSlides = slides.length; var tracker = 0; $('.slider-height').css('height', slideHeight * numberOfSlides); $('.slide-option li a').click(function() { tracker = $('.slide-option li a').index($(this)); $('.slide-option li a').removeClass('current-item'); $(this).addClass('current-item'); //alert(tracker); $('.slider-height').animate({ 'top': slideHeight * (-tracker) }); return false; //alert(tracker); }); });

• Is it possible to supply template parameters when calling operator()?

  - by Paul

  I'd like to use a template operator() but am not sure if it's possible. Here is a simple test case that won't compile. Is there something wrong with my syntax, or is this simply not possible? struct A { template<typename T> void f() { } template<typename T> void operator()() { } }; int main() { A a; a.f<int>(); // This compiles. a.operator()<int>(); // This compiles. a<int>(); // This won't compile. return 0; }

• java-maven2: How to include the a jar as depedency in pom so that I will be able to access test clas

  - by flavour-of-bru

  Hi, I have a set of functional jars(more than 3) that tests my source code. These jars just contains test classes and assisting asserter classes. I am creating a new performance jar that would import all the functional tests from these jars so that all can be run simultaneously. But when I include them as test dependencies in pom of current jar, what all I get to see is the classes in src/main/java. How can I include these functional jars as dependent jars so that I can also reference classes in src/test/java. In other words, how do I reference the test classes in other jars. In what way should I include the dependency as. Thanks for your support.

• Why is the output like this?

  - by javatechi

  class another { public void method(Object o) { System.out.println("This is in method which takes object"); } public void method(String s) { System.out.println("This is method which takes string"); } } public class NewClass { public static void main(String args[]) { another an = new another(); an.method(null); } } When I try to execute this, I get This is method which takes string as the output. Why not "This is in method which takes object"? Object can also be null and string can also be null, why doesn't it invoke first method?

• Use of class definitions inside a method in Java

  - by Bragaadeesh

  Hi public class TestClass { public static void main(String[] args) { TestClass t = new TestClass(); } private static void testMethod(){ class TestMethodClass{ int a; int b; int c; } TestMethodClass testMethodClass = new TestMethodClass(); } } I found out that the above piece of code is perfectly legal in Java. I have the following questions. What is the use of ever having a class definition inside a method? Will a class file be generated for TestMethodClass Its hard for me to imagine this concept in an Object Oriented manner. Having a class definition inside a behavior. Probably can someone tell me with equivalent real world examples. Thanks

• ALT-TAB Application Icon Pixelated

  - by Red Potato

  When a child window of my application is opened and I view the ALT-TAB menu, the application icon looks pixellated. I assume that Windows uses a low resolution version of the icon (16x16 pixel I think). What can I do that Windows selects the right version which would be 32x32 pixel? I assigned an icon to the window in question that has 16x16, 24x24, 32x32, 48x38 and 256x256 in true color. Please note that VS says in the proterties that 32x32 is used and that it works fine for the main window of my application where I assigned the exact same icon.

• Why does a non-constant offsetof expression work?

  - by Chris J. Kiick

  Why does this work: #include <sys/types.h> #include <stdio.h> #include <stddef.h> typedef struct x { int a; int b[128]; } x_t; int function(int i) { size_t a; a = offsetof(x_t, b[i]); return a; } int main(int argc, char **argv) { printf("%d\n", function(atoi(argv[1]))); } If I remember the definition of offsetof correctly, it's a compile time construct. Using 'i' as the array index results in a non-constant expression. I don't understand how the compiler can evaluate the expression at compile time. Why isn't this flagged as an error?

• I have an Xcode static library project, how do I add a test target to it so I can run it there? (Ins

  - by zekel

  I want to be able to test library code in the library target so I don't have to switch over to a separate project to run it. I see how to add a target, but I'm not sure how to set it up to run like the "Command Line Tool" project template does. I tried adding a new "Shell Tool" target, but I don't know how to make it run like one. What build settings do I have to add to that target? What files (main.m?) do I need to start it up?

• Using PHP's exec() function (or the likes), how can you display terminal error output?

  - by Miciah Amberong

  Previous Reference I am just wondering if there's a way (using PHP) to output the compile error information from the terminal to the browser? For example: If you use this code to execute in the terminal... gcc -o try try.c ...and assuming the "try.c" have some errors. The terminal will output something like this: try.c In function 'main': try.c:27 'x' undeclared (first use in this function) try.c:27 (Each undeclared identifier is reported only once try.c:27 for each function it appears in.) Meanwhile, using this PHP code... <?php exec("gcc -o try try.c"); ?> The browser does not return any output like the terminal does. Is there a possible way direct or indirect that the error details that the terminal showed can be passed to the be displayed on a browser? Thank you very much.

• Problem with nhibernate join

  - by MexicanHacker

  I'm trying to do a join like this using fluent nhibernate: Id(x => x.Id); Map(x => x.SourceSystemRecordId,"sourceSystemRecord_id"); Then Join("cat.tbl_SourceSystemRecords", SourceSystemRecords); But, it seems I don't have a way to specify the column I want to join with from the first table, in this case I need to join on SourceSystemRecordId and not on Id Is there any way I can specify this? I tried References() but that requires me to create an object for this relationship, what I need is to aggregate the columns in sourcesystem records to the ones in the main table.

• How can I close the currently running server app when I launch new debug session?

  - by Eonil

  Google App Engine (GAE) Java SDK uses eclipse as main IDE. IDE runs a server app when I launch debugging session. And it runs another server app when I launch debugging session again. It closes the server app when I stop the debugging session, but it doesn't when I re-launch debugging session. Re-launching means stop and launch again. Why does it stop existing app? So I have to close the server app manually at each time. Is there a way to close existing running app when re-launching debugging session?
