  • How do I set a value to the Session in asp.net on an onClick event of a normal htmlElement?

    - by William Calleja
    I need to make a Function that receives a Session Key and a Session Value and call this function on a normal HTML onClick event. When this function is called the Session variable is assigned the Key I sent with the Value I sent. So far I have this: <script runat="server" type="text/C#"> protected void setSessionValue(string key, string value) { Session[key] = value; } </script> But when I try to call if like so: onclick="setSessionValue('itemID','3345');" Its not working and giving me an error. Any help? I'm using c# and asp.net but I can't use code behind and need to work everything off the page.

  • Can phper give me some code snippet to consume the .net wcf service

    - by Vincent
    Hi, I can successfully make a call to wcf from php without WCF message security enabled. I search the whole forum and cannot find any clue. I'd like to know how can I pass the credential ? My WCF service use the basichttpbinding on SSL with Message security enabled. Here is my code snippet to call my wcf from .NET ServiceReference1.TestClient sc = new TestClient(); sc.ClientCredentials.UserName.UserName = "[email protected]"; sc.ClientCredentials.UserName.Password = "ABC123"; Console.WriteLine(sc.GetProfiledSchemas(412));

  • Calling a JAVA method from C++ with JNI, no parameters

    - by PRNDL Development Studios
    Please bear with me, I am an iPhone developer and this whole android this confuses me a bit. I have some c++ methods that are called from a cocos2d-x CCMenuItem. Therefore I cannot send any parameters, according to the docs. I need to open a url with the android browser which will require me to call a JAVA function to start a new intent. I understand that I need to create a VM, however the below code gives me the error: jni/../../Classes/MyClass.cpp:184: error: 'JNI_CreateJavaVM' was not declared in this scope I was looking at this thread: Calling a java method from c++ in Android But he uses parameters, and I can't do that. And I don't see where those are in his code to just make them myself. I don't know what the string should be in the 'Find Class' method. Also, I assume it is pretty terrible to create a new VM instance in every method I need to call. How would I create one as a singleton to use across the board? This is my c++ code called by my menu item: #include <jni.h> ... JavaVM *vm; // Global ... void OptionsScene::website(){ JNIEnv *env; JavaVMInitArgs vm_args; vm_args.version = JNI_VERSION_1_2; vm_args.nOptions = 0; vm_args.ignoreUnrecognized = 1; jint result = JNI_CreateJavaVM(&vm, (void **)&env, &vm_args); // This line still errors jclass clazz = env->FindClass("com/prndl/project/WebExecute"); jmethodID method = env->GetMethodID(clazz, "website", "(Ljava/lang/String;)V"); env->CallVoidMethod(NULL,method); vm->DestroyJavaVM(); And this is the JAVA Method that I need to call: public class WebExecute extends Activity{ public void website(){ Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")); startActivity(browserIntent); } } Honestly, I am struggling with this, any help is appreciated. Thanks.

  • How to abandon a hg merge?

    - by Grumdrig
    I'm new to collaborating with Mercurial. My situation: Another programmer changed rev 1 of a file to replace 4-space indents with 2-space indent. (I.e. changed every line.) Call that rev 2, pushed to the remote repo. I've committed substantive changes rev 1 with various code changes in my local workspace. Call that rev 3. I've hg pulled and hg merged without a clear idea of what was going on. The conflicts are myriad and not really substantive. So I really wish I'd changed my local repo to 2-space indents before merging; then the merge will be trivial (i'm supposing). But I can't seem to back up. I think I need to hg update -r 3 but it says abort: outstanding uncommitted merges. How can I undo the merge, changes spacing in my local repo, and remerge?

  • Zend Framework: My custom form filter is not filtering!

    - by Andrew
    So I have a form that is using a custom filter (which is really just a copy of Zend_Filter_Null). When I call it directly, it works: $makeZeroNull = new My_Filter_MakeZeroNull(); $null = $makeZeroNull->filter('0'); //$null === null However, when I try to add it to an element in my form, it doesn't filter the value when I call getValue(). class My_Form extends Zend_Form { public function init() { $makeZeroNull = new My_Filter_MakeZeroNull(); $this->addElement('text', 'State_ID', array('filters' => array($makeZeroNull))); } } //in controller if ($form->isValid($_POST)) { $zero = $form->State_ID->getValue(); //getValue() should return null, but it is returning 0 } What is going on? What am I doing wrong?

  • iPhone memory management (with specific examples/questions)

    - by donkim
    Hey all. I know this question's been asked but I still don't have a clear picture of memory management in Objective-C. I feel like I have a pretty good grasp of it, but I'd still like some correct answers for the following code. I have a series of examples that I'd love for someone(s) to clarify. Setting a value for an instance variable. Say I have an NSMutableArray variable. In my class, when I initialize it, do I need to call a retain on it? Do I do fooArray = [[[NSMutableArray alloc] init] retain]; or fooArray = [[NSMutableArray alloc] init]; Does doing [[NSMutableArray alloc] init] already set the retain count to 1, so I wouldn't need to call retain on it? On the other hand, if I called a method that I know returns an autoreleased object, I would for sure have to call retain on it, right? Like so: fooString = [[NSString stringWithFormat:@"%d items", someInt] retain]; Properties. I ask about the retain because I'm a bit confused about how @property's automatic setter works. If I had set fooArray to be a @property with retain set, Objective-C will automatically create the following setter, right? - (void)setFooArray:(NSMutableArray *)anArray { [fooArray release]; fooArray = [anArray retain]; } So, if I had code like this: self.fooArray = [[NSMutableArray alloc] init]; (which I believe is valid code), Objective-C creates a setter method that calls retain on the value assigned to fooArray. In this case, will the retain count actually be 2? Correct way of setting a value of a property. I know there are questions on this and (possibly) debates, but which is the right way to set a @property? This? self.fooArray = [[NSMutableArray alloc] init]; Or this? NSMutableArray *anArray = [[NSMutableArray alloc] init]; self.fooArray = anArray; [anArray release]; I'd love to get some clarification on these examples. Thanks!

  • How to create an MSI package that installs no files and only executes some commands using Wix

    - by Sevas
    I am trying to create an MSI package that uses the AppCmd application to configure IIS7. It only has to execute some commands that call AppCmd. Some commands need to be called when installing, other commands need to be called when uninstalling. Here is what I have now: I have a property that points to AppCmd: <Property Id="APPCMD" Value="C:\Windows\system32\inetsrv\appcmd.exe" /> I have my custom actions: <CustomAction Id="UnlockHandlerSection" Return="check" Property="APPCMD" ExeCommand="unlock config /section:system.webServer/handlers" /> I have Custom elements that call the actions: <InstallExecuteSequence> <Custom Action="UnlockHandlerSection" After="InstallFiles">NOT Installed AND NOT PATCH</Custom> <InstallExecuteSequence> The problem with this is is that the commands are not called when I try to install the resulting MSI package. Could anyone please advise me on what I am doing wrong? Thank you!

  • DispatcherOperations.Wait()

    - by Mark
    What happens if you call dispatcherOperation.Wait() on an operation that has already completed? Also, the docs say that it returns a DispatcherOperationStatus, but wouldn't that always be Completed since it (supposedly) doesn't return until it's done? I was trying to use it like this: private void Update() { while (ops.Count > 0) ops.Dequeue().Wait(); } public void Add(T item) { lock (sync) { if (dispatcher.CheckAccess()) { list.Add(item); OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, item)); } else { ops.Enqueue(dispatcher.BeginInvoke(new Action<T>(Add), item)); } } } I'm using this in WPF, so all the Add operations have to occur on the UI thread, but I figured I could basically just queue them up without having to wait for it to switch threads, and then just call Update() before any read operations to ensure that the list is up to date, but my program started hanging.

  • Function calls in virtual machine killing performance

    - by GenTiradentes
    I wrote a virtual machine in C, which has a call table populated by pointers to functions that provide the functionality of the VM's opcodes. When the virtual machine is run, it first interprets a program, creating an array of indexes corresponding to the appropriate function in the call table for the opcode provided. It then loops through the array, calling each function until it reaches the end. Each instruction is extremely small, typically one line. Perfect for inlining. The problem is that the compiler doesn't know when any of the virtual machine's instructions are going to be called, as it's decided at runtime, so it can't inline them. The overhead of function calls and argument passing is killing the performance of my VM. Any ideas on how to get around this?

  • resort on a std::vector vs std::insert

    - by Abruzzo Forte e Gentile
    I have a sorted std::vector of relative small size ( from 5 to 20 elements ). I used std::vector since the data is continuous so I have speed because of cache. On a specific point I need to remove an element from this vector. I have now a doubt: which is the fastest way to remove this value between the 2 options below? setting that element to 0 and call sort to reorder: this has complexity but elements are on the same cache line. call erase that will copy ( or memcpy who knows?? ) all elements after it of 1 place ( I need to investigate the behind scense of erase ). Do you know which one is faster? I think that the same approach could be thought about inserting a new element without hitting the max capacity of the vector. Regards AFG

  • iphone singleton object synchronization

    - by user127091
    I'm working on an iphone app but this is probably a general question. I have a singleton Model class and there would be scenarios where multiple NSOperations (threads) would exist and work with the singleton object. If they all call the same method in this object, do i need to have some locking mechanism? Or can this method be executed only one at a time? I do not have a computer science background but my guess is that all threads would have their CALL to the same address (this method). Also can you please suggest a good beginner programming book that discusses general programming concepts. I don't have the brains for Knuth kinda books.

  • How do I post to a webservice and display the returned Response in MVC3 Razor Application?

    - by DavieDave
    I have need to call a webservice from an HTML helper extension I created (combinbation of Action and Image) and placed in the view as follows @Html.ActionImage("CallService", new { number = ViewBag.number, code = ViewBag.code, account = ViewBag.account, amount = ViewBag.amount }, "~/Content/sb_200x61.png", "Start the Process") I am making the action call and it calls the service and returns a string of the html response, but it doesn't look right. I am using the typical HttpWebRequest to do the POST Action in C# code. Here is the controller action code: public MvcHtmlString CallService(string number, string code, string account, decimal? amount) { string response = MyService.ServiceLayer.ClassName.callService(number, code, account, Convert.ToDecimal(amount); MvcHtmlString mstring = new MvcHtmlString(response); return mstring; } When it returns the string back it's looking like the all styling and js is removed. It that due to MvcHtmlString? Is there a better way to do this? Redirect somehow ?

  • Replacing whitespace with sed in a CSV (to use w/ postgres copy command)

    - by Wells
    I iterate through a collection of CSV files in bash, running: iconv --from-code=ISO-8859-1 --to-code=UTF-8 ${FILE} | \ sed -e 's/\"//g' | \ sed -e 's/, /,/g' \ > ${FILE}.utf8 Running iconv to fix UTF-8 characters, then the first sed call removes the double quote characters, and the final sed call is supposed to remove leading and trailing whitespace around the commas. HOWEVER, I still have a line like this in the saved file: FALSE,,,, 2.40,, The COPY command in postgres is kind of dumb, so it thinks " 2.40" is not valid syntax for a numeric value. Where am I going wrong w/ my processing of the CSV file? Thanks!

  • Subprocess with variables & Command from different class

    - by Pastelinux
    source: http://pastebin.com/utL7Ebeq My thinking is that if i run from controller class "main" it will allow me to take the "data" from Class "model", def "filename". It doesn't seem to work. As you can see below what i mean class Controller: def __init__(self): self.model = Model() self.view = View() def main(self): data = self.model.filename() self.view.tcpdump(data) class View: def tcpdump(self, command): subprocess.call(command.split(), shell=False) When i run my code i get this error: subprocess.call(command.split(), shell=False) AttributeError: 'NoneType' object has no attribute 'split' My guess means that its not picking up command (look at source for reference) or that its not getting command with variables. But i know the error when variables are not being picked up so i don't think it is that. My question is, from what i have thus far, how do i from "class view" grab "command" for my subprocesses to run. Thanks~ John Riselvato

  • class method as hash value

    - by demas
    I have this working code: class Server def handle(&block) @block = block end def do @block.call end end class Client def initialize @server = Server.new @server.handle { action } end def action puts "some" end def call_server @server.do end end client = Client.new client.call_server My Server will handle more then one action so I want to change code such way: class Server def handle(options) @block = options[:on_filter] end def do @block.call end end class Client def initialize @server = Server.new my_hash = { :on_filter => action } @server.handle(my_hash) end def action puts "some" end def call_server @server.do end end client = Client.new client.call_server It is incorrect code because action() method calls on create my_hash, but if I try to modify code to: my_hash = { :on_filter => { action } } i get error message. Is it possible to create hash with methods as hash values ?

  • C++ setTimout function ?

    - by Quandary
    What's the cheapest way for a JavaScript like setTimeout-function in C++? I would need this: 5000 miliseconds from now, start function xy (no parameters, no return value). The reason for this is I need to initialize COM for text to speech, but when I do it on dll attach, it crashes. It works fine however if I do not call CoInitialize from dllmain. I just need to call CoInitialize and CoCreateInstance, and then use the instance in other functions. I can catch the uninitialized instance by checking for NULL, but I need to initialize COM - without crashing.

  • Calling Tortoise from command line and build if new code (how to know if tortoise updated anything)?

    - by Iakob
    I am writing a batch file which is supposed to update the source files from tortoise and - if anything new was gotten - build the solution. Should be a very simple task. My batchfile looks like this (I've removed the non-essentials) set updatepath=%1 set solution=%2 set output=%3.txt call TortoiseProc.exe /command:update /path:%updatepath% /closeonend:2 call %devenv% %solution% /Build Debug /Out %output% Now, I'd like to know if tortoise actually got new code for me and the not build if it didn't. How do I do this? I am running Windows Vista (The batch script is called from another batch script about 7 times - one for each project I need updated and - perhaps - build).

  • How do i translate this to "simpler" JavaScript?

    - by Julian Weimer
    Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

  • Methods in the namespace System.Security.Cryptography take 2 minutes to perform when service is hosted in IIS

    - by Asaf Saf
    I built an ASP.NET web-service that uses the System.Security.Cryptography namespace when it handles its requests. When I hosted the service in ASP.NET Development Server, everything worked fine. Then I moved the service into IIS, still using localhost addresses, and surprisingly, each time the service calls a method from the specified namespace, it takes 2 minutes to complete! If a single request requires the service to call 3 methods of the specified namespace, then the request takes total of 6 minutes to complete! The traces show that the request has been received on time, and they show an interval of around 2 minutes upon each call to the specified namespace. Did anyone see this strange behavior elsewhere? Any speculation would be appreciated!

  • Why in Objective-C, we use self = [super init] instead of just [super init]?

    - by ????
    In a book, I saw that if a subclass is overriding a superclass's method, we may have self = [super init]; First, is this supposed to be done in the subclass's init method? Second, I wonder why the call is not just [super init]; ? I mean, at the time of calling init, the memory is allocated by alloc already (I think by [Foobar alloc] where Foobar is the subclass's name. So can't we just call [super init] to initialize the member variables? Why do we have to get the return value of init and assign to self? I mean, before calling [super init], self should be pointing to a valid memory allocation chuck... so why assigning something to self again? (if assigning, won't [super init] just return self's existing value?)

  • Where are the function literals c++?

    - by academicRobot
    First of all, maybe literals is not the right term for this concept, but its the closest I could think of (not literals in the sense of functions as first class citizens). The idea is that when you make a conventional function call, it compiles to something like this: callq <immediate address> But if you make a function call using a function pointer, it compiles to something like this: mov <memory location>,%rax callq *%rax Which is all well and good. However, what if I'm writing a template library that requires a callback of some sort with a specified argument list and the user of the library is expected to know what function they want to call at compile time? Then I would like to write my template to accept a function literal as a template parameter. So, similar to template <int int_literal> struct my_template {...};` I'd like to write template <func_literal_t func_literal> struct my_template {...}; and have calls to func_literal within my_template compile to callq <immediate address>. Is there a facility in C++ for this, or a work around to achieve the same effect? If not, why not (e.g. some cataclysmic side effects)? How about C++0x or another language? Solutions that are not portable are fine. Solutions that include the use of member function pointers would be ideal. I'm not particularly interested in being told "You are a <socially unacceptable term for a person of low IQ>, just use function pointers/functors." This is a curiosity based question, and it seems that it might be useful in some (albeit limited) applications. It seems like this should be possible since function names are just placeholders for a (relative) memory address, so why not allow more liberal use (e.g. aliasing) of this placeholder. p.s. I use function pointers and functions objects all the the time and they are great. But this post got me thinking about the don't pay for what you don't use principle in relation to function calls, and it seems like forcing the use of function pointers or similar facility when the function is known at compile time is a violation of this principle, though a small one.

  • How to make Dajax callback into scoped object

    - by BozoJoe
    I cant seem to find a way to make django-dajaxice have its callback inside same scoped object from which made the initial call. MyViewport = Ext.extend(MyViewportUi, { initComponent: function() { MyViewport.superclass.initComponent.call(this); }, LoadRecordsCallback: function(data){ if(data!='DAJAXICE_EXCEPTION') { alert(data); } else { alert('DAJAXICE_EXCEPTION'); } }, LoadRecords: function(){ Dajaxice.Console.GetUserRecords(this.LoadRecordsCallback); } }); var blah = new MyViewport(); blah.LoadRecords(); I'm on django, and like the calling syntax to django-dajaxice. I'm using Extjs 3.2 and tried passing a Ext.createCallback but Dajax's returning eval seems to only want a string for the callback.
