  • Performing an action on Parent/Child elements independently.

    - by Matt Weldon
    I have HTML similar to the following in my page <div id="someDiv"> <img src="foo.gif" class="someImg" /> </div> The wrapper div is set up such that when it is clicked, it's background-color changes using the following jQuery code. $("div").click(function(event){ $(this).css("background-color", "blue"); }); I also have some jQuery associated with my img that will do some other function (for the sake of argument I am going to display and alert box) like so: $("img[class=someImg]").click(function(event){ alert("Image clicked"); }); The issue I have come across is that when I click on the img, the event associated with the div is also triggered. I'm pretty sure that this is due to the way that jQuery (or indeed JavaScript) is handling the two DOM elements - clicking the img would require you to also technically click the div, thus triggering both events. Two questions then really: Is my understanding of the DOM/JavaScript flawed in some way or is this actually how things are occurring? Are there any jQuery methods that would allow me to perform actions on a child element without invoking those associated with its parent?

  • jQuery: How do I rewrite .after( content, content )?

    - by Evan Carroll
    I've got this form working, but according to my previous question it might not be supported: it isn't in the docs either way -- but the intention is pretty obvious in the code. $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); What this does is insert <div class="little check"> with a simple .click() callback, followed by a sibling of <span>OEM</span>. How else can I write this then? I'm having difficulty conjuring something working by chaining any combination of .after(), and .insertAfter()? I would expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ).after ( $('<span>OEM</span>') ) ); I would also expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<span>OEM</span>').insertAfter( $('<div class="little check" />').click( function () { alert('hi') } ) ); );

  • Passing a string to a function in C++

    - by Chef Flambe
    I want to pass a string like "Celcius" into a function that I have but I keep getting errors tossed back at me from the Function. System::Console::WriteLine' : none of the 19 overloads could convert all the argument types I figure I just have something simple wrong. Can someone point out my mistake please? Using MS Visual C++ 2010 I've posted the offending code. The other functions (not posted) work fine. void PrintResult( double result, std::string sType ); // Print result and string // to the console //============================================================================================= // start of main //============================================================================================= void main( void ) { ConsoleKeyInfo CFM; // Program Title and Description ProgramDescription(); // Menu Selection and calls to data retrieval/calculation/result Print CFM=ChooseFromMenu(); switch(CFM.KeyChar) // ************************************************************ { //* case '1' : PrintResult(F2C(GetTemperature()),"Celsius"); //* break; //* //* case '2' : PrintResult(C2F(GetTemperature()),"Fahrenheit"); //* break; //* //* default : Console::Write("\n\nSwitch : Case !!!FAILURE!!!"); //* } //************************************************************ system("pause"); return; } //Function void PrintResult( double result, std::string sType ) { Console::WriteLine("\n\nThe converted temperature is {0:F2} degrees {1}\n\n",result,sType); return; }

  • Coding the R-ight way - avoiding the for loop

    - by mropa
    I am going through one of my .R files and by cleaning it up a little bit I am trying to get more familiar with writing the code the r-ight way. As a beginner, one of my favorite starting points is to get rid of the for() loops and try to transform the expression into a functional programming form. So here is the scenario: I am assembling a bunch of data.frames into a list for later usage. dataList <- list (dataA, dataB, dataC, dataD, dataE ) Now I like to take a look at each data.frame's column names and substitute certain character strings. Eg I like to substitute each "foo" and "bar" with "baz". At the moment I am getting the job done with a for() loop which looks a bit awkward. colnames(dataList[[1]]) [1] "foo" "code" "lp15" "bar" "lh15" colnames(dataList[[2]]) [1] "a" "code" "lp50" "ls50" "foo" matchVec <- c("foo", "bar") for (i in seq(dataList)) { for (j in seq(matchVec)) { colnames (dataList[[i]])[grep(pattern=matchVec[j], x=colnames (dataList[[i]]))] <- c("baz") } } Since I am working here with a list I thought about the lapply function. My attempts handling the job with the lapply function all seem to look alright but only at first sight. If I write f <- function(i, xList) { gsub(pattern=c("foo"), replacement=c("baz"), x=colnames(xList[[i]])) } lapply(seq(dataList), f, xList=dataList) the last line prints out almost what I am looking for. However, if i take another look at the actual names of the data.frames in dataList: lapply (dataList, colnames) I see that no changes have been made to the initial character strings. So how can I rewrite the for() loop and transform it into a functional programming form? And how do I substitute both strings, "foo" and "bar", in an efficient way? Since the gsub() function takes as its pattern argument only a character vector of length one.

  • Why in the world is this Moq + NUnit test failing?

    - by Dave Falkner
    I have this dataAccess mock object and I'm trying to verify that one of its methods is being invoked, and that the argument passed into this method fulfills certain constraints. As best I can tell, this method is indeed being invoked, and with the constraints fulfilled. This line of the test throws a MockException: data.Verify(d => d.InsertInvoice(It.Is<Invoice>(i => i.TermPaymentAmount == 0m)), Times.Once()); However, removing the constraint and accepting any invoice passes the test: data.Verify(d => d.InsertInvoice(It.IsAny<Invoice>()), Times.Once()); I've created a test windows form that instantiates this test class, runs its .Setup() method, and then calls the method which I am wishing to test. I insert a breakpoint on the line of code where the mock object is failing the test data.InsertInvoice(invoice); to actually hover over the invoice, and I can confirm that its .TermPaymentAmount decimal property is indeed zero at the time the method is invoked. Out of desperation, I even added a call back to my dataAccess mock: data.Setup(d => d.InsertInvoice(It.IsAny<Invoice>())).Callback((Invoice inv) => System.Windows.Forms.MessageBox.Show(inv.TermPaymentAmount.ToString("G17"))); And this gives me a message box showing "0". This is really baffling me, and no one else in my shop has been able to figure this out. Any help would be appreciated. A barely related question, which I should probably ask independently, is whether it is preferable to use Mock.Verify(...) as I have here, or to use Mock.Expect(...).Verifiable followed by Mock.VerifyAll() as I have seen other people doing? If the answer is situational, which situations would warrent the use of one over the other?

  • "Address of" (&) an array / address of being ignored be gcc?

    - by dbarbosa
    Hi, I am a teaching assistant of a introductory programming course, and some students made this type of error: char name[20]; scanf("%s",&name); which is not surprising as they are learning... What is surprising is that, besides gcc warning, the code works (at least this part). I have been trying to understand and I wrote the following code: void foo(int *str1, int *str2) { if (str1 == str2) printf("Both pointers are the same\n"); else printf("They are not the same\n"); } int main() { int test[50]; foo(&test, test); if (&test == test) printf("Both pointers are the same\n"); else printf("They are not the same\n"); } Compiling and executing: $ gcc test.c -g test.c: In function ‘main’: test.c:12: warning: passing argument 1 of ‘foo’ from incompatible pointer type test.c:13: warning: comparison of distinct pointer types lacks a cast $ ./a.out Both pointers are the same Both pointers are the same Can anyone explain why they are not different? I suspect it is because I cannot get the address of an array (as I cannot have & &x), but in this case the code should not compile.

  • Running Java Program linking to thirdpary library (java -jar) issue ( Multiple methods tried )

    - by bamachrn
    This issue is related to running a Java program (jar) dependent on thirdparty jar library even after setting classpath and trying so many other methods by reading articles in Internet. I want to use a thirdparty Pack1.jar (it is not a part of jvm) as dependency of my programme. I do not know where the Pack1.jar file could be in the deployment machine and I want the deployer to specify the path for the thirdparty libraries I have tried the following alternatives in vain Setting the java.class.path programatically String class_path = args[0]; System.setProperty("java.class.path",class_path); Here I am assuming that deployer would supply the classpath as first argument while running the program Setting the CLASSPATH env_var to locate the thirdparty directory While running, using the classpath option java -classpath /path/to/Pack1.jar -jar Pack2.jar I think this would not work because documentation says that classpath is ignored when program is run with "java -jar" Setting the java.ext.dirs programatically. Setting the java.library.path programatically. I do not want to specify the Class-Path in manifest because that takes only relative path and I do not know where the thirdparty library would be kept in deployment machine But I am unable to get the jar running. How can I fix this problem any help please.

  • In Lua, can I easily select the Nth result without custom functions?

    - by romkyns
    Suppose I am inserting a string into a table as follows: table.insert(tbl, mystring) and that mystring is generated by replacing all occurrences of "a" with "b" in input: mystring = string.gsub(input, "a", "b") The obvious way to combine the two into one statement doesn't work, because gsub returns two results: table.insert(tbl, string.gsub(input, "a", "b")) -- error! -- (second result of gsub is passed into table.insert) which, I suppose, is the price paid for supporting multiple return values. The question is, is there a standard, built-in way to select just the first return value? When I found select I thought that was exactly what it did, but alas, it actually selects all results from N onwards, and so doesn't help in this scenario. Now I know I can define my own select as follows: function select1(n, ...) return arg[n] end table.insert(tbl, select1(1, string.gsub(input, "a", "b"))) but this doesn't look right, since I'd expect a built-in way of doing this. So, am I missing some built-in construct? If not, do Lua developers tend to use a separate variable to extract the correct argument or write their own select1 functions?

  • Improved technique to store a filename in a variable?

    - by SDGuero
    Greetings, I need to store the filename of a log into a variable so my script can perform some checks on the daily log files. These logs always have a different name because they have a timestamp in the name. Currently I'm using a hodge podged method that pipes an ls command to sed, sort, cut, and tail in order to get the name out. CRON_LOG=$(ls -1 $LOGS_DIR/fetch_cron_{true,false}_$CRON_DATE*.log 2> /dev/null | sed 's/^[^0-9][^0-9]*\([0-9][0-9]*\).*/\1 &/' | sort -n | cut -d ' ' -f2- | tail -1 ) UPDATE: $CRON_DATE is supplied as an argument to the script. It is the date (to the day) that the log was created on. Sometimes multiple logs will exist for the same day so I want this to get the most recent one. A typical filename is fetch_cron_false_031810090452.log I'm pretty sure I kluged this together from some stuff I found google a few months ago. it works now but I'm not really happy with the technique. I have some ideas about how to do this better but I have had great success on this site before and thought it might be best to refer to the stackoverflow gods first. All answers are greatly appreciated. Thanks, Ryan

  • Porting VB6 app to VB.Net: Can anyone ballpark how much effort this is?

    - by Robusto
    In 2002 I did a pretty large VB6 app for a client. It used a lot of UserControls and a 3rd party menu control (for putting icons next to menu names). It had dynamically "splittable" panels, TreeViews with multi-state checkboxes, etc. A very rich UI. My total time on the project was about 500 hours, which the client graciously let me spread over a whole month. (Yeah, it was that kind of job.) They were very happy, though, and they paid the bill on time with no argument. So after having no contact with them for years, they suddenly call and wonder if I can update the app to .Net for them. My initial reaction is just to decline, since I don't use VB.Net. And having read a bunch of posts on SO about the difficulties of porting, etc., etc., I'm even more inclined to decline, so to speak. Still, before I tell them no I am interested in roughly quantifying the effort it would take. I would love to hear from anyone who has done this kind of thing and has a feel for how much work it is. Was it: Significantly less than the effort you used on the original? Somewhat less than the effort you used on the original? The same as the effort you used on the original? More? A lot more? Please only respond if you have actually done this kind of port. And the answer doesn't have to be exact, since I really am only trying to ballpark this. My feeling is that the effort will be at least as much as it took for the original, if not more. But I could be wrong. Thanks for any help.

  • problem with a string's format in c++ while doing tcp communication

    - by james t
    hi, i am building a simple c++ client, i am splitting the info i get from the server to frames, and pass each frame to a function that processes it, i split the frame into lines using Poco::StringTokenizer tokenizer(frame, "\n"); i take the first line of the tokenizer which represents the type of frame StmpCommand command(tokenizer[0]); a StmpCommand is an enum with the different types of messages and the constructor works as follows : StmpCommand(std::string command): commandType_() { bool x=command=="CONNECTED"; std::cout<<x<<std::endl; if ("SUBSCRIBE" == command) commandType_ = SUBSCRIBE; else if ("UNSUBSCRIBE" == command) commandType_ = UNSUBSCRIBE; else if ("SEND" == command) commandType_ = SEND; else if ("BEGIN" == command) commandType_ = BEGIN; else if ("COMMIT" == command) commandType_ = COMMIT; else if ("CONNECT" == command) commandType_ = CONNECT; else if ("MESSAGE" == command) commandType_ = MESSAGE; else if ("RECEIPT" == command) commandType_ = RECEIPT; else if ("CONNECTED" == command) commandType_ = CONNECTED; else if ("DISCONNECT" == command) commandType_ = DISCONNECT; else if ("ERROR" == command) commandType_ = ERROR; else { std::cerr<<"Error in building StmpCommand object, unknown type - "<<command<<std::endl; } } the first frame i am trying to proccess is a CONNECTED frame therefor i try to create a StmpCommand with CONNECTED as the constructor's only argument and for some reason i am getting an : Error in building StmpCommand object, unknown type - CONNECTED i am clearly passing a string containing CONNECTED but i'm guessing there is something else there that isn't allowing the condition else if ("CONNECTED" == command) to hap

  • (Java) Is there a type of object that can handle anything from primitives to arrays?

    - by Michael
    I'm pretty new to Java, so I'm hoping one of you guys knows how to do this. I'm having the user specify both the type and value of arguments, in any XML-like way, to be passed to methods that are external to my application. Example: javac myAppsName externalJavaClass methodofExternalClass [parameters] Of course, to find the proper method, we have to have the proper parameter types as the method may be overloaded and that's the only way to tell the difference between the different versions. Parameters are currently formatted in this manner: (type)value(/type), e.g. (int)71(/int) (string)This is my string that I'm passing as a parameter!(/string) I parse them, getting the constructor for whatever type is indicated, then execute that constructor by running its method, newInstance(<String value>), loading the new instance into an Object. This works fine and dandy, but as we all know, some methods take arrays, or even multi-dimensional arrays. I could handle the argument formatting like so: (array)(array)(int)0(/int)(int)1(/int)(/array)(array)(int)2(/int)(int)3(/int)(/array)(/array)... or perhaps even better... {{(int)0(/int)(int)1(/int)}{(int)2(/int)(int)3(/int)}}. The question is, how can this be implemented? Do I have to start wrapping everything in an Object[] array so I can handle primitives, etc. as argObj[0], but load an array as I normally would? (Unfortunately, I would have to make it an Object[][] array if I wanted to support two-dimensional arrays. This implementation wouldn't be very pretty.)

  • [SOLVED]Django - Passing variables to template based on db

    - by George 'Griffin
    I am trying to add a feature to my app that would allow me to enable/disable the "Call Me" button based on whether or not I am at [home|the office]. I created a model in the database called setting, it looks like this: class setting(models.Model): key = models.CharField(max_length=200) value = models.CharField(max_length=200) Pretty simple. There is currently one row, available, the value of it is the string True. I want to be able to transparently pass variables to the templates like this: {% if available %} <!-- Display button --> {% else %} <!-- Display grayed out button --> {% endif %} Now, I could add logic to every view that would check the database, and pass the variable to the template, but I am trying to stay DRY. What is the best way to do this? UPDATE I created a context processor, and added it's path to the TEMPLATE_CONTEXT_PROCESSORS, but it is not being passed to the template def available(request): available = Setting.objects.get(key="available") if open.value == "True": return {"available":True} else: return {} UPDATE TWO If you are using the shortcut render_to_response, you need to pass an instance of RequestContext to the function. from the django documentation: If you're using Django's render_to_response() shortcut to populate a template with the contents of a dictionary, your template will be passed a Context instance by default (not a RequestContext). To use a RequestContext in your template rendering, pass an optional third argument to render_to_response(): a RequestContext instance. Your code might look like this: def some_view(request): # ... return render_to_response('my_template.html', my_data_dictionary, context_instance=RequestContext(request)) Many thanks for all the help!

  • Redirecting http to https for a directory, via .htaccess, using mod_alias only

    - by Belinda
    I have the common problem of wanting to redirect requests for a certain restricted access directory from http to https, so that users' login credentials are sent in a secure way. However, I do not have mod_rewrite enabled on my server. I only have mod_alias. This means I have to use the RedirectMatch command. I can't use the usual solutions that use RewriteCond and RewriteRule. (A note on the politics: I am a small-fry subsite maintainer in a very large organisation, so the server admins are unlikely to be willing to change the server config for me!) The following line works, but forms an infinite loop (because the rewritten URL is still caught by the initial regular expression): RedirectMatch permanent ^/intranet(.*)$ https://example.com/intranet$1 One of my internal IT guys has suggested I avoid the infinite loop by moving the files to a new directory with a new name (eg /intranet2/). That seems pretty ugly to me. And people could still accidentally/deliberately revert to an insecure connection by visiting http://example.com/intranet2/ directly. Then I tried this, but it didn't work: RedirectMatch permanent ^http:(.*)/intranet(.*)$ https://example.com/intranet$1 I suspect it didn't work because the first argument must be a file path from the root directory, so it can't start with "http:". So: any better ideas how to do this?

  • Generic delegate instances

    - by Luc C
    I wonder if C# (or the underlying .NET framework) supports some kind of "generic delegate instances": that is a delegate instance that still has an unresolved type parameter, to be resolved at the time the delegate is invoked (not at the time the delegate is created). I suspect this isn't possible, but I'm asking it anyway... Here is an example of what I'd like to do, with some "???" inserted in places where the C# syntax seems to be unavailable for what I want. (Obviously this code doesn't compile) class Foo { public T Factory<T>(string name) { // implementation omitted } } class Test { public void TestMethod() { Foo foo = new Foo(); ??? magic = foo.Factory; // No type argument given here yet to Factory! // What would the '???' be here (other than 'var' :) )? string aString = magic<string>("name 1"); // type provided on call int anInt = magic<int>("name 2"); // another type provided on another call // Note the underlying calls work perfectly fine, these work, but i'd like to expose // the generic method as a delegate. string aString2 = foo.Factory<string>("name 1"); int anInt2 = foo.Factory<int>("name 2"); } } Is there a way to actually do something like this in C#? If not, is that a limitation in the language, or is it in the .NET framework?

  • PHP - How do you secure a unique variable name?

    - by 102319141763223461745
    This function cropit, which I shamelessly stole off the internet, crops a 90x60 area from an existing image. In this code, when I use the function for more than one item (image) the one will display on top of the other (they come to occupy the same output space). I think this is because the function has the same (static) name ($dest) for the destination of the image when it's created (imagecopy). I tried, as you can see to include a second argument to the cropit function which would serve as the "name" of the $dest variable, but it didn't work. In the interest of full disclosure I have 22 hours of PHP experience (incidentally the same number of hours since the last I slept) and I am not that smart to begin with. Even if there's something else at work here entirely, seems to me that generally it must be useful to have a way to secure that a variable is always given a unique name. function cropit($srcimg, $dest) { $im = imagecreatefromjpeg($srcimg); $img_width = imagesx($im); $img_height = imagesy($im); $width = 90; $height = 60; $tlx = floor($img_width / 2) - floor ($width / 2); $tly = floor($img_height / 2) - floor ($height / 2); if ($tlx < 0) { $tlx = 0; } if ($tly < 0) { $tly = 0; } if (($img_width - $tlx) < $width) { $width = $img_width - $tlx; } if (($img_height - $tly) < $height) { $height = $img_height - $tly; } $dest = imagecreatetruecolor ($width, $height); imagecopy($dest, $im, 0, 0, $tlx, $tly, $width, $height); imagejpeg($dest); imagedestroy($dest); } $img = "imagefolder\imageone.jpg"; $img2 = "imagefolder\imagetwo.jpg"; cropit($img, $i1); cropit($img2, $i2); ?

  • How to process a large post array in PHP where item names are all different and not known in advance

    - by Salnajjar
    I have a PHP page that queries a DB to populate a form for the user to modify the data and submit. The query returns a number of rows which contain 3 items: ImageID ImageName ImageDescription The PHP page titles each box in the form with a generic name and appends the ImageID to it. Ie: ImageID_03 ImageName_34 ImageDescription_22 As it's unknown which images are going to have been retrieved from the DB then I can't know in advance what the name of the form entries will be. The form deals with a large number of entries at the same time. My backend PHP form processor that gets the data just sees it as one big array: [imageid_2] => 2 [imagename_2] => _MG_0214 [imageid_10] => 10 [imagename_10] => _MG_0419 [imageid_39] => 39 [imagename_39] => _MG_0420 [imageid_22] => 22 [imagename_22] => Curly Fern [imagedescription_2] => Wibble [imagedescription_10] => Wobble [imagedescription_39] => Fred [imagedescription_22] => Sally I've tried to do an array walk on it to split it into 3 arrays which set places but am stuck: // define empty arrays $imageidarray = array(); $imagenamearray = array(); $imagedescriptionarray = array(); // our function to call when we walk through the posted items array function assignvars($entry, $key) { if (preg_match("/imageid/i", $key)) { array_push($imageidarray, $entry); } elseif (preg_match("/imagename/i", $key)) { // echo " ImageName: $entry"; } elseif (preg_match("/imagedescription/i", $key)) { // echo " ImageDescription: $entry"; } } array_walk($_POST, 'assignvars'); This fails with the error: array_push(): First argument should be an array in... Am I approaching this wrong?

  • Android SDK and Java

    - by Soonts
    Android SDK Manager complains "WARNING: Java not found in your path". Instead of using the information from Windows registry, the software tries to search Java in the default installation folders, and fails (I don't install software in program files because I don't like space characters in my paths). Of course I know how to modify the %PATH% environment variable. The question is — which Java does it need? After installing the latest JDK, I’ve got 4 distinct versions of java.exe file, in the following 4 folders: system32, jre6\bin, jdk1.6.0_26\bin, and jdk1.6.0_26\jre\bin. Size ranges from 145184 to 171808. All of them print version “1.6.0_26” when launched with the “-version” argument. The one in system32 has .exe version “6.0.250.6”, the rest of them is “6.0.260.3”. All 4 files are different (I’ve calculated the MD5 checksums). Q1. Which folder should I add to %PATH% to make the Android SDK happy? Q2. Why does Oracle build that many variants of java.exe of the same version for the same platform? Thanks in advance! P.S. I'm using Windows 7 SP1 x64 home premium, and downloaded the 64-bit version of JDK, jdk-6u26-windows-x64.exe.

  • pathogen#infect not updating the runtimepath

    - by Taylor Price
    I have started working with pathogen.vim with gvim on Windows, following Tim Pope's setup guide at his github repository here. However, I'm running into the problem that pathogen#infect() does not seem to be modifying the runtimepath (as seen by running :echo &runtimepath in gvim). The simple test case _vimrc that I came up with is as follows. Please note that pathogen gets loaded just fine. "Set a base directory. let $BASE_DIR='H:\development\github\vimrc' "Source pathogen since it's not in the normal autoload directory. source $BASE_DIR\autoload\pathogen.vim "Start up pathogen call pathogen#infect() "call pathogen#infect('$BASE_DIR\functions') Neither running pathogen#infect() without an argument (which should add the bundles directory under the vimfiles directory) nor specifying a directory to contain files works. Substituting the pathogen#infect() call with pathogen#runtime_prepend_subdirectories('$BASE_DIR\functions'), which is what pathogen#infect() does fails to change the runtimepath as well. Any ideas that I've missed? Any more information that would be helpful? My repository with the non-trivial example is here.

  • Creating a assertClass() method in JUnit

    - by Mike
    Hi, I'm creating a test platform for a protocol project based on Apache MINA. In MINA when you receive packets the messageReceived() method gets an Object. Ideally I'd like to use a JUnit method assertClass(), however it doesn't exist. I'm playing around trying to work out what is the closest I can get. I'm trying to find something similar to instanceof. Currently I have: public void assertClass(String msg, Class expected, Object given) { if(!expected.isInstance(given)) Assert.fail(msg); } To call this: assertClass("Packet type is correct", SomePacket.class, receivedPacket); This works without issue, however in experimenting and playing with this my interest was peaked by the instanceof operator. if (receivedPacket instanceof SomePacket) { .. } How is instanceof able to use SomePacket to reference the object at hand? It's not an instance of an object, its not a class, what is it?! Once establishing what type SomePacket is at that point is it possible to extend my assertClass() to not have to include the SomePacket.class argument, instead favouring SomePacket?

  • Generic Singleton Fasade design pattern

    - by Paul
    Hi I try write singleton fasede pattern with generics. I have one problem, how can I call method from generic variable. Something like this: T1 t1 = new T1(); //call method from t1 t1.Method(); In method SingletonFasadeMethod I have compile error: Error 1 'T1' does not contain a definition for 'Method' and no extension method 'Method' accepting a first argument of type 'T1' could be found (are you missing a using directive or an assembly reference?) Any advace? Thank, I am beginner in C#. All code is here: namespace GenericSingletonFasade { public interface IMyInterface { string Method(); } internal class ClassA : IMyInterface { public string Method() { return " Calling MethodA "; } } internal class ClassB : IMyInterface { public string Method() { return " Calling MethodB "; } } internal class ClassC : IMyInterface { public string Method() { return "Calling MethodC"; } } internal class ClassD : IMyInterface { public string Method() { return "Calling MethodD"; } } public class SingletonFasade<T1,T2,T3> where T1 : class,new() where T2 : class,new() where T3 : class,new() { private static T1 t1; private static T2 t2; private static T3 t3; private SingletonFasade() { t1 = new T1(); t2 = new T2(); t3 = new T3(); } class SingletonCreator { static SingletonCreator() { } internal static readonly SingletonFasade<T1,T2,T3> uniqueInstace = new SingletonFasade<T1,T2,T3>(); } public static SingletonFasade<T1,T2,T3> UniqueInstace { get { return SingletonCreator.uniqueInstace; } } public string SingletonFasadeMethod() { //Problem is here return t1.Method() + t2.Method() + t3.Method(); } } }

  • session_set_cookie_params on multi-domain sites

    - by nillls
    Hi! I'm currently developing for an application (www.domain.se, .eu) where we're experiencing problems with sessions not propagating across domains. Internet Explorer is the root cause of this, as it will differentiate sessions depending on whether we're typing in "domain.se" or "www.domain.se". Due to some unfortunate redirecting, we're not able to keep the user on the same address the user typed in, instead we're always redirecting to www.domain.se on login. Needless to say, IE users can not login when typing "domain.se". To make this error go away, we implemented a function to try and set the session to be valid across all possible domains by doing the following: if($_SERVER['HTTP_HOST'] == "domain.se") { session_set_cookie_params(3600, '/', '.domain.se', true); } There are basically a few if:s that we go through depending on what address the user typed in, but the third argument stays the same. This, however, results in no-one being able to log in, regardless of domain. I've tried reading up on how session_set_cookie_params() works but to no avail. Any help is greatly appreciated!
