  • js function causing all other functions not to work inside js file

    - by Camran
    In safari 4 and all explorer browsers, whenever I try to call a function inside a javascript file which contains this function below, that first function isn't called. So calling function1 will not work if function2 is inside the same .js file, explanation? Here is the code which makes the problem. Whenever I remove this function, everything works fine and all functions work fine. So this function is causing a problem. function addOption(selectbox, value, text, class, id_nr ) { var optn = document.createElement("OPTION"); optn.text = text; optn.value = value; optn.id = value; if (class==1){ optn.className = "nav_option_main"; } selectbox.options.add(optn); } Any ideas why? Thanks

  • In WPF, how do I update the object that my custom property is bound to?

    - by Timothy Khouri
    I have a custom property that works perfectly, except when it's bound to an object. The reason is that once the following code is executed: base.SetValue(ValueProperty, value); ... then my control is no longer bound. I know this because calling: base.GetBindingExpression(ValueProperty); ... returns the binding object perfectly - UNTIL I call base.SetValue. So my question is, how do I pass the new "value" on to the object that I'm bound to?

  • Deserialising Json to derived types in Asp.Net Web API

    - by IoChaos
    I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

  • How to calculate number of leap years between two years in C#

    - by Vlad Bezden
    Hi All, Is there a better way to calculate number of leap years between two years. Assuming I have start date and end date. I have my code, but I think there should be more elegant way. calling code: var numberOfLeapYears = NumberOfLeapYears(startDate.Year + 1, endDate.Year - 1); function itself: private static int NumberOfLeapYears(int startYear, int endYear) { var counter = 0; for (var year = startYear; year <= endYear; year++) counter += DateTime.IsLeapYear(year) ? 1 : 0; return counter; } So if I have startDate = "10/16/2006" and endDate = "4/18/2004" I should only have 1 leap year (2000) in result. Another words startDate's Year and endDate's year should not be calculated, only years in between. Thanks in advance for your help.

  • how to use proxy with JSON

    - by Dele
    I have a php page called 'dataFetch.php' which sits on one webserver. On another webserver, I have a JS file which issues JSON calls to dataFetch. dataFetch connects to a database, retrieves data and puts it in a JSON format which is fed back to the calling program. In IE, this works fine. In other browsers it does not because of the cross domain restriction. To get across the cross-domain restriction, I make a call to a file, proxy.php, which then makes the call to dataFetch. My problem now is that proxy.php retrieves the file from dataFetch but the JS script file no longer sees the response from proxy.php as a JSON format and so I can't process it. Can anybody help me out?

  • Issue with webview with emulator and some devices Android

    - by Yasir Khan
    I am developing an application that is focuses on on WebView i am loading map from a webpage and calling subsequent java script request on it but i do not know what is happening with Galaxy Tab 7' and my emulator too after running well first time if i visit the application again its just showing blank page.

  • stop cript debug error dialogs occur in ie8 ?

    - by Haroldo
    I get this, clicking 'no' means the page displays flawlessly. it's refering to this part of jquery1.4.2.js: // Get the Nth element in the matched element set OR // Get the whole matched element set as a clean array get: function( num ) { return num == null ? // Return a 'clean' array this.toArray() : // Return just the object ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] ); }, I assume i'm calling something in the wrong context somewhere in one of my js files (which would be a real mission to find). Will standard IE8 users get this error? (i imagine ms make it pretty difficult to reinstall ie!)

  • Ajax response is taking time to populate.

    - by Rachel
    I am having an util class which is not owned by me. I am calling one of the method of that util class which inturn calls one ajax function. And gives me response back. I need to make a decision depending on the response object. The problem is that response object takes some time to populate(mili seconds). var selector = dojo.byId("SelectorId"); var theChart = new chart( selector, 135, 92, style, frequency, time); if(theChart.data ===null){ console.log("No response"); }else{ Console.log("Use response data"); } and chart( selector, 135, 92, style, frequency, time); is not owned by me. chart() is from util class. above snippet works fine with break point. But when I remove the breakpoint it starts going in "if" block always. Hows can I solve this issue.

  • How to get function's name from function's pointer in C?

    - by Daniel Silveira
    How to get function's name from function's pointer in C? Edit: The real case is: I'm writing a linux kernel module and I'm calling kernel functions. Some of these functions are pointers and I want to inspect the code of that function in the kernel source. But I don't know which function it is pointing to. I thought it could be done because, when the system fails (kernel panic) it prints out in the screen the current callstack with function's names. But, I guess I was wrong... am I?

  • I want to retrieve some information based on Caller ID

    - by Hassan Al-Jeshi
    Hello, my friend has a Real Estate company that receives a lot of phone calls everyday. He wants to have a solution such that when somebody call to his company, the operator sees all the information about the person who is calling based on the database he have right now and the caller ID. Is there a ready made software or solution that can do the job?? Since I'm a software engineer myself, I would never mind developing something from scratch or built on a ready made system (with a team of course), but I need some direction on how to start?? Notes: 1- cost is not an issue 2- the customers database is there but we never mind replacing it in a format to suit the new solution Best Regards,

  • Proper thread termination in multi-threaded C# application

    - by Brian
    I have what I think is a rather complex problem. I have a C# application that utilizes a plug-in architecture using reflection. The application loads plug-in dlls and the user is able to enable/disable them. When a plug-in is enabled, the main app starts a thread to run the plug-in in. In many cases the plug-in may have multiple threads of its own. When I want to disable a plug-in I am calling Thread.Abort(). This seems to kill the initial thread that was created for the plug-in, but any additional threads that the plug-in created continue running. Is there a better way to stop all of the associated plug-in's threads along with the main thread? Thanks.

  • jQuery switchClass

    - by Eric
    Is it possible to undo a switchClass transaition? I'd like an element to slowly obtain class A as you hover over it, and slowly lose it again once the mouse has moved away. However, the function appears to be glitchy, and calling .stop(0,1) doesn't seem to help. In fact, it seems to break it. I have a live example here. Yes, it's a 404 page, but that's not important. The navigation should be slowly gaining or losing a class, but it just jumps. The script can be found here. Is such a transition possible?

  • Python: How to run unittest.main() for all source files in a subdirectory?

    - by Pete
    I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

  • pass custom environment variables to System.Diagnostics.Process

    - by Mike Ruhlin
    I'm working on an app that invokes external processes like so: ProcessStartInfo startInfo = new ProcessStartInfo(PathToExecutable, Arguments){ ErrorDialog = false, RedirectStandardError = true, RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true, WorkingDirectory = WorkingDirectory }; using (Process process = new Process()) { process.StartInfo = startInfo; process.Start(); process.BeginErrorReadLine(); process.BeginOutputReadLine(); process.WaitForExit(); return process.ExitCode; } One of the processes I'm calling depends on an environment variable that I'd rather not require my users to set. Is there any way to modify the environment variables that get sent to the external process? Ideally I'd be able to make them visible only to the process that's running, but if I have to programmatically set them system-wide, I'll settle for that (but, would UAC force me to run as administrator to do that?) ProcessStartInfo.EnvironmentVariables is read only, so a lot of help that is...

  • Do bit operations cause programs to run slower?

    - by flashnik
    I'm dealing with a problem which needs to work with a lot of data. Currently its values are represented as an unsigned int. I know that real values do not exceed a limit of 1000. Questions I can use unsigned short to store it. An upside to this is that it'll use less storage space to store the value. Will performance suffer? If I decided to store data as short but all the calling functions use int, it's recognized that I need to convert between these datatypes when storing or extracting values. Will performance suffer? Will the loss in performance be dramatic? If I decided to not use short but just 10 bits packed into an array of unsigned int. What will happen in this case comparing with previous ones?

  • JNI AttachCurrentThread NULLs the jenv

    - by Damg
    Hello all, I'm currently in the process of adding JNI functionality into a legacy delphi app. In a single-threaded environment everything works fine, but as soon as I move into multi-threaded environment, things start to become hairy. My problem is that calling JavaVM^.AttachCurrentThread( JavaVM, @JEnv, nil ); returns 0, but puts the JEnv pointer to nil. I have no idea why jvm.dll should return a NULL pointer. Is there anything I am missing? Thank you in advance -- damg PS: * Environment: WinXP + JDK 1.6 * Using JNI.pas from http://www.pacifier.com/~mmead/jni/delphi/

  • Test-driven Development: Writing tests for private / protected variables

    - by Chetan
    I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

  • Treeview Slow in IE?!?!

    - by Mike
    I have a treeview with around 200 records that needs to be fully expanded at all times (so no loading on demand). It is inside of an update panel with the updatemode set to conditional. There are other update panels on the page as well that are set to conditional. Depending on user actions the tree may need to be rebuilt by calling databind and updating the updatepanel. Everything works fine in firefox, longest postback about 2 seconds. With IE I have to wait up to 30 seconds sometimes and the action may have nothing to do with the tree just changing a dropdown in its own updatepanel takes forever. I have considered the size of viewstate and just raw HTML generated may be causing the delay but wouldn't that effect both browsers? Anyone have anyideas what is making it so slow in IE??? Thanks!

  • How to show ajax loading gif only for a specific request?

    - by innerJL
    How do you show ajax gif only for a specific request? For example my page is calling a web-service every 30 seconds in a background, and I don't want to show the gif during this callback. On the other hand I want to show the gif, when I'am making manual ajax requests. I am using jQuery. edit: I didn't setup the global handler as shown here http://api.jquery.com/ajaxStart/, just by attaching to the .ajaxStart event. But I don't want to show/hide the gif manually on every request too. I need some generic solution.
