  • calling function in radiobutton group

    - by vijisai
    thank you very much. with your help, i am now able to call the function for each radio button. however, i get a error message Reference to non-existent field 'ics_si' ics_si is my function, which has the following code, i do not know where i am making a mistake i have created the edit box for user to input the values for bore and stroke. and vdisp is calculated and the result is displayed in the third edit box. function ics_si_Callback(hObject, eventdata, handles) b = str2double(get(handles.bore,'String')); s = str2double(get(handles.stroke,'String')); vdisp = (pi * b * b * s*10^(-3))/4; set(handles.vdisp,'String',vdisp); this code must be called when i press the first or second radio button. i.e. when the radio button is pressed, it should call the function ics_si, calculate it and display the result. how to get this.

    - by Jenuel
    I have an existing project using c/c++ .NET. Currently I have been given a task to create a windows form from my existing code. So i have add new project windows form application in the existing c/c++ projects.form.h, form.cpp has been automatically created. Now I am having problem to call the window from my c files. Even i could not call the form.h file from my c program. Is there any solution for this problem. Listed here is the coding.... login.c int LoginMain(int id,int task) { LoginClear(); LoginEntry(id,task); dp_in = 1; Rep(); //I WOULD LIKE TO CALL THE FORM AT THIS STAGE Cashier(); dp_in = 0; Login(); return(0); } form.cpp [STAThreadAttribute] int main(array ^args) { // Enabling Windows XP visual effects before any controls are created Application::EnableVisualStyles(); Application::SetCompatibleTextRenderingDefault(false); // Create the main window and run it Application::Run(gcnew Form1()); return 0; }

  • call function inside a nested jquery plugin

    - by tchoesang
    There are many topics related to my question and i have been through most of them, but i haven't got it right. The closest post to my question is the following: http://stackoverflow.com/questions/1042072/how-to-call-functions-that-are-nested-inside-a-jquery-plugin Below is the jquery plugin i am using. On resize, the element sizes are recalculated. I am now trying to call the function resizeBind() from outside of the jquery plugin and it gives me error I tried the following combinations to call the function $.fn.splitter().resizeBind() $.fn.splitter.resizeBind() Any ideas, where i am getting wrong? ;(function($){ $.fn.splitter = function(args){ //Other functions ...... $(window).bind("resize", function(){ resizeBind(); }); function resizeBind(){ var top = splitter.offset().top; var wh = $(window).height(); var ww = $(window).width(); var sh = 0; // scrollbar height if (ww <0 && !jQuery.browser.msie ) sh = 17; var footer = parseInt($("#footer").css("height")) || 26; splitter.css("height", wh-top-footer-sh+"px"); $("#tabsRight").css("height", splitter.height()-30+"px"); $(".contentTabs").css("height", splitter.height()-70+"px"); } return this.each(function() { }); }; })(jQuery);

  • C#: Hijacking a near relative call

    - by Lex
    Alright, I'm trying to write a vary basic modification to a program NOT written by me. I DO NOT have the source to it. I also do not care if this only works for a single version of the program, so hard coding offsets is feasible. Anyways, I've found the function and where it is called in the compiled program. .text:1901C88F loc_1901C88F: ; CODE XREF: ConnectionThread+1A2j .text:1901C88F ; DATA XREF: .text:off_1901CC64o .text:1901C88F 8B C8 mov ecx, eax ; jumptable 1901C862 case 11 .text:1901C891 8B C6 mov eax, esi .text:1901C893 E8 48 C5 FF FF call ChatEvent According to IDA the full function signature is: char *__usercall ChatEvent<eax>(char *Data<eax>, unsigned int Length<ecx>) I already have all I need to patch the program during runtime, and do whatever other manipulations I need. What I need, is to be able to write a function like so: bool ProcessChat(char *Data, unsigned int Length); char *__usercall HijackFunction(char *Data, unsigned int Length){ if (ProcessChat(Data, Length)) Call OriginalChatEvent(Data, Length); } Get the jist of what I am trying to do? With stdcall function it's easy just replace the 4 byte address with my own function's address. But this is a near relative call, which is.. more annoying. So, anyone have any idea?

  • Which hosting will let me execute my own EXE with PHP?

    - by guitar-
    I have a task that PHP (or any server-side scripting language) isn't practical for. It involves a lot of file I/O, processing, etc. and it will execute a lot faster using the program I made in C instead of PHP. Do any hosts allow you to upload your own EXE files and run them on the server using PHP's exec, shell_exec, etc. functions? Do you need a dedicated server to do this? Also, I don't know if Facebook's PHP HipHop is out yet, but I really don't want to use that.

  • WCF net.tcp windows service - call duration and calls outstanding increases over time

    - by Brook
    I have a windows service which uses the ServiceHost class to host a WCF Service using the net.tcp binding. I have done some tweaking to the config to throttle sessions as well as number of connections, but it seems that every once in a while my "Calls outstanding" and "Call duration" shoot up and stay up in perfmon. It seems to me I have a leak somewhere, but the code I have is all fairly minimal, I'm relying on ServiceHost to handle the details. Here's how I start my service ServiceHost host = new ServiceHost(type); host.Faulted+=new EventHandler(Faulted); host.Open(); My Faulted event just does the following (more or less, logging etc removed) if (host.State == CommunicationState.Faulted) { host.Abort(); } else { host.Close(); } host = new ServiceHost(type); host.Faulted+=new EventHandler(Faulted); host.Open(); Here's some snippets from my app.config to show some of the things I've tried <runtime> <gcConcurrent enabled="true" /> <generatePublisherEvidence enabled="false" /> </runtime> ......... <behaviors> <serviceBehaviors> <behavior name="Throttled"> <serviceThrottling maxConcurrentCalls="300" maxConcurrentSessions="300" maxConcurrentInstances="300" /> .......... <services> <service name="MyService" behaviorConfiguration="Throttled"> <endpoint address="net.tcp://localhost:49001/MyService" binding="netTcpBinding" bindingConfiguration="Tcp" contract="IMyService"> </endpoint> </service> </services> .......... <netTcpBinding> <binding name="Tcp" openTimeout="00:00:10" closeTimeout="00:00:10" portSharingEnabled="true" receiveTimeout="00:5:00" sendTimeout="00:5:00" hostNameComparisonMode="WeakWildcard" listenBacklog="1000" maxConnections="1000"> <reliableSession enabled="false"/> <security mode="None"/> </binding> </netTcpBinding> .......... <!--for my diagnostics--> <diagnostics performanceCounters="ServiceOnly" wmiProviderEnabled="true" /> There's obviously some resource getting tied up, but I thought I covered everything with my config. I'm only getting about ~150 clients so I don't think I'm coming up against my "300" limit. "Calls per second" stays constant at anywhere from 2-5 calls per second. The service will run for hours and hours with 0-2 "calls outstanding" and very low "call duration" and then eventually it will shoot up to 30 calls oustanding and 20s call duration. Any tips on what might be causing my "calls outstanding" and "call duration" to spike? Where am I leaking? Point me in the right direction?

  • Simple jquery ajax call leaks memory in ie.

    - by Thomas Lane
    I created a web page that makes an ajax call every second. In Internet Explorer 7, it leaks memory badly (20MB in about 15 minutes). The program is very simple. It just runs a javascript function that makes an ajax call. The server returns an empty string, and the javascript does nothing with it. I use setTimout to run the function every second, and I'm using Drip to watch the thing. Here is the source: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout('testJunk()',1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){} }); setTimeout('testJunk()',1000) } </script> </head> <body> Why is memory usage going up? </body> </html> Anyone have an idea how to plug this leak? I have a real application that updates a large table this way, but left unattended will eat up Gigabytes of memory. Okay, so after some good suggestions, I modified the code to: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout(testJunk,1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){setTimeout(testJunk,1000)} }); } </script> </head> <body> Why is memory usage going up? </body> </html> It didn't seem to make any difference though. I'm not doing anything with the DOM, and if I comment out the ajax call, the memory leak stops. So it looks like the leak is entirely in the ajax call. Does jquery ajax inherently create some sort of circular reference, and if so, how can I free it? By the way, it doesn't leak in Firefox. Someone suggested running the test in another VM and see if the results are the same. Rather than setting up another VM, I found a laptop that was running XP Home with IE8. It exhibits the same problem. I tried some older versions of jquery and got better results, but the problem didn't go away entirely until I abandoned ajax in jquery and went with more traditional (and ugly) ajax.

  • Is it bad practice to call a controller action from a view that was rendered by another controller?

    - by marco-fiset
    Let's say I have an OrderController which handles orders. The user adds products to it through the view, and then the final price gets calculated through an AJAX call to a controller action. The price calculation logic is implemented in a seperate class and used in a controller action. What happens is that I have many views from different controllers that need to use that particular action. I'd like to have some kind of a PriceController that I could call an action on. But then the view would have to know about that PriceController and call an action on it. Is it bad practice for a view to call an action on a different controller from which it was rendered?

  • passing parameters to jQuery's select2 ajax call

    - by Cary
    I'm attempting to pass an extra parameter to an ajax call within select2: $(".auto-sug").select2({ width:'element', minimumInputLength:2, ajax: { url: "/action/get-custom.php", data: function (term, page) { return { q: term, // search term page_limit: 10 }; }, results: function (data, page) { return {results: data.stuff}; } } }); I actually want to pass another parameter to the ajax call... the id of the element itself <input type="text" class="auto-sug" name="custom" id="3383" /> however, I'm unable to figure out how to actually access the id of the element (3383) or any other value on the page. select2: http://ivaynberg.github.com/select2/

  • Call a function in an ExtJS XTemplate

    - by Snowright
    I'm familiar with using a function to determine a specific condition using xtemplate but not sure how to directly call a function without the conditional if statement. My code, for example, wants to append some characters to a string that I am using within my xtemplate. I think the best way to do it is append the characters when the xtemplate is rendered. var myTpl = new Ext.XTemplate( '<tpl for=".">', '<tpl if="this.isThumbnailed(thumbnailed) == true">', '<img src=this.getThumbUrl(rawThumbUrl)/>', //this call to function does not work, also tried variations of this. '</tpl>', '</tpl>', { isThumbnailed : function(thumbnailed) { return ...; }, getThumbUrl : function(rawThumbUrl) { //... //this function does not get called. return ...; } } )

  • Ajax call to wcf windows service over ssl (https)

    - by bpatrick100
    I have a windows service which exposes an endpoint over http. Again this is a windows service (not a web service hosted in iis). I then call methods from this endpoint, using javascript/ajax. Everything works perfectly, and this the code I'm using in my windows service to create the endpoint: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("http://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); webServiceHost.Open(); Now, my goal is to get this same model working over SSL (https not http). So, I have followed the guidance of several msdn pages, like the following: http://msdn.microsoft.com/en-us/library/ms733791(VS.100).aspx I have used makecert.exe to create a test cert called "bpCertTest". I have then used netsh.exe to configure my port (1213) with the test cert I created, all with no problem. Then, I've modified the endpoint code in my windows service to be able to work over https as follows: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("https://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); binding.Security.Mode = WebHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); webServiceHost.Credentials.ServiceCertificate.SetCertificate("CN=bpCertTest", StoreLocation.LocalMachine, StoreName.My); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpsGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpsBinding(), "mex"); webServiceHost.Open(); The service creates the endpoint successfully, recognizes my cert in the SetCertificate() call, and the service starts up and running with success. Now, the problem is my javascript/ajax call cannot communicate with the service over https. I simply get some generic commication error (12031). So, as a test, I changed the port I was calling in the javascript to some other random port, and I get the same error - which tells me that I'm obviously not even reaching my service over https. I'm at a complete loss at this point, I feel like everything is in place, and I just can't see what the problem is. If anyone has experience in this scenario, please provide your insight and/or solution! Thanks!

  • .NET Webservice Client: Auto-retry upon call failure

    - by Yon
    Hi, We have a .NET client calling a Java webservice using SSL. Sometimes the call fails due to poor connectivity (the .NET Client is a UI that is used from the weirdest locations). We would like to implement an automatic retry mechanism that will automatically retry a failed call X times before giving up. This should be done solely with specific types of connectivity exceptions (and not for exceptions generated by the web service itself). We tried to find how to do it on the Binding/Channel level, but failed... any ideas? Thanks, yonadav

  • IE8 + Jquery ajax call giving parsererror : for json data which seems valid in Firefox

    - by PlanetUnknown
    The ajax call works fine in FF. the data returned is in JSON here is an example from FF firebug - {"noProfiles": "No profiles have been created, lets start now !"} When I try to print the error in IE8 (& in compatibility modes as well), it says "parsererror". But the output seems to be valid JSON. Here is the ajax function call I'm making. Any pointers would be great ! $.ajax({ type: "GET", url: "/get_all_profile_details/", data: "", dataType: "json", beforeSend: function() {alert("before send called");}, success: function(jsonData) { alert("data received"); }, error: function(xhr, txt, err){ alert("xhr: " + xhr + "\n textStatus: " + txt + "\n errorThrown: " + err); } }); The alerts in the error function above give - xhr:<blank> textstatus:parsererror errorThrown: undefined Any pointers would be great ! Note : jquery : 1.3.2

  • SqlCommand - preventing stored proc call in other databases

    - by Moe Sisko
    When using SqlCommand to call a stored proc via RPC, it looks like it is possible to call a stored proc in a database other than the current database. e.g. : string storedProcName = "SomeOtherDatabase.dbo.SomeStoredProc"; SqlCommand cmd = new SqlCommand(storedProcName); cmd.CommandType = CommandType.StoredProcedure; I'd like to make my DAL code more restrictive, by disallowing potential calls to another database. One way might be to check if there are two periods (dots) in storedProcName above, and if so, throw an exception. Any other ideas/approaches ? Thanks.

  • call a class method from inside an instance method from a module mixin (rails)

    - by sean
    Curious how one would go about calling a class method from inside an instance method of a module which is included by an active record class. For example I want both user and client models to share the nuts and bolts of password encryption. # app/models class User < ActiveRecord::Base include Encrypt end class Client < ActiveRecord::Base include Encrypt end # app/models/shared/encrypt.rb module Encrypt def authenticate # I want to call the ClassMethods#encrypt_password method when @user.authenticate is run self.password_crypted == self.encrypt_password(self.password) end def self.included(base) base.extend ClassMethods end module ClassMethods def encrypt_password(password) Digest::SHA1.hexdigest(password) end end end However, this fails. Says that the class method cannot be found when the instance method calls it. I can call User.encrypt_password('password') but User.new.encrypt_password fails Any thoughts?

  • Core Data iPhone how often should I call [managedObjectContext save:&error] when doing 50k record in

    - by jamone
    I will be doing an occiasional import from XML into core data. I have around 50k entities that will be added. My question is how often should I call [managedObjectContext save:&error]. For every new entity added, or every x entities, or just at the end of the 50k import? I currently am calling it for each entity and tried only doing it for around every 10k and import speed went up drastically but after the first 30k it would crash with: *** Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <NSCFSet: 0x13e760> was mutated while being enumerated.' Before I spend too much time trying to diagnose what is going on there I figured I'd check if its ok to not call save on every entity? Is the # of entities before calling save limited by the amount of memory those entities are using?

  • Linux Kernel programming: trying to get vm_area_struct->vm_start crashes kernel

    Hi, this is for an assignment at school, where I need to determine the size of the processes on the system using a system call. My code is as follows: ... struct task_struct *p; struct vm_area_struct *v; struct mm_struct *m; read_lock(&tasklist_lock); for_each_process(p) { printk("%ld\n", p->pid); m = p->mm; v = m->mmap; long start = v->vm_start; printk("vm_start is %ld\n", start); } read_unlock(&tasklist_lock); ...

  • WebTest Visual Studio Test problems with amf call

    - by Lieven Cardoen
    If I browse to a flex application when recording with VS Test, I can see the calls to WebORB (amf calls). However, when stopping the recording this is what happens: First, Visual Studio detects dynamic parameters, but stays around 20%, and never gets through it. Second, if I cancel the detecting dynamic parameters, and run the web test, the calls to WebORB (amf calls) do not work. In fact, in VS2010, the call to WebORB stays on Submitting... Now, this web test, does it only record url's and query string variables, or does it record the whole request? If it records the whole request, the call to WebORB should work, but it doesn't.

  • Retry web service call if authentication failure requires re-login

    - by Pete
    I'm consuming a web service from C#, and the web service requires a login call and then uses cookie sessions. The web service will time out sessions after a certain timeframe, after which the client will have to re-login. I'd like to find a way to automatically catch the soap fault the service sends back in this scenario, and handle it by re-logging in and then retrying the previously attempted call. I would prefer to do this somehow automatically for all the web service methods in question, rather than having to manually wrap the calls with the retry logic. Suggestions?

  • Generating a Call Hierarchy for dynamicly invoked method

    - by Maxim Veksler
    Hello, Today's world of dynamic invoke, reflection and runtime injection just doesn't play well with traditional tools such as ctags, doxygen and CDOC. I am searching for a method call hierarchy visualization tool that can display both static and dynamic method invocations. It should be easy to use, light during execution and provide helpful detailed information about the recorded runtime session. Now I guess Callgrind could be considered a valid solution for the family C. What tool / technique could you suggest to create a call graph for both static and dynamic method invocation for JVM based bytecode? The intended end result is a graphical display (preferably interactive) which can show path from main() to each method that was invoked. During research for this post I stumbled upon javashot, it seems that this is the kind of approach I'm aiming at, I would prefer that this would be integrated into a kind of profiler or alike which than can be used from within my IDE (Eclipse, IntelliJ, Netbeans and alike). Thank you, Maxim.
