  • c#, Internal, and Reflection

    - by cyberconte
    Duplicate of: Accessing internal members via System.Reflection? Is there a way to execute "internal" code via reflection? Here is an example program: using System; using System.Reflection; namespace ReflectionInternalTest { class Program { static void Main(string[] args) { Assembly asm = Assembly.GetExecutingAssembly(); // Call normally new TestClass(); // Call with Reflection asm.CreateInstance("ReflectionInternalTest.TestClass", false, BindingFlags.Default | BindingFlags.CreateInstance, null, null, null, null); // Pause Console.ReadLine(); } } class TestClass { internal TestClass() { Console.WriteLine("Test class instantiated"); } } } Creating a testclass normally works perfectly, however when i try to create an instance via reflection, I get a missingMethodException error saying it can't find the Constructor (which is what would happen if you tried calling it from outside the assembly). Is this impossible, or is there some workaround i can do?

  • Complicated conditional SQL query

    - by DevAno1
    I'm not even sure if it's possible but I need it for my Access database. So I have following db structure : Now I need to perform a query that takes category_id from my product and do the magic : - let's say product belongs to console (category_id is in table Console) - from console_types take type_id, where category_id == category_id - but if product belongs to console_game (category_id is in table console_game) - from console_game take game_cat_id, where category_id == category_id I'm not sure if mysql is capable of such thing. If not I'm really f&%ranked up. Maybe there is a way to split this into 2,3 separate queries ?

  • What can cause a persistent "Reload the page to get source for" error in firebug?

    - by ripper234
    I'm trying to debug the javascript of a specific page, and I keep seeing Reload the page to get source for page.htm in Firebug. On Chrome, I'm mostly able to debug the js, but sometimes I also get a blank page. What can cause such issues? I believe I always see a blank page in Chrome if I reload while the JS console is open. If I open a new Chrome tab, load the page, and then open the JS console, everything is ok. The page I'm debugging is on a localhost server (Play Framework server), although I have seen this on other pages occasionally. This only happens with inline javascript ... js that is linked from the page is displayed fine.

  • What benefits can Java developer have from moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse on it, so there will be no big difference. Guys, who use Java on *NIX, could you please give me some real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • problem getting the height of a UIScrollView

    - by funkadelic
    hi, i am setting the size of a UIScrollView in viewDidLoad: but when I try to get the height of it, i am getting 0 in the console here is my code: - (void)viewDidLoad { [scrollView setContentSize:CGSizeMake(320,500)]; NSLog(@"scrollView: %@", scrollView); NSLog(@"scrollView.contentSize.height: %i", scrollView.contentSize.height); [super viewDidLoad]; } and in the console log i get scrollView: <UIScrollView: 0x4974110; frame = (0 0; 320 367); clipsToBounds = YES; autoresize = RM+TM; layer = <CALayer: 0x4974010>> scrollView.contentSize.height: 0 Shouldn't scrollView.contentSize.height be returning 367? On a related note, i specified the height to be 500 via [scrollView setContentSize:], but that doesn't appear to be applied?

  • How to force HttpWebRequest to use cache in ASP.NET environment?

    - by piotrsz
    In my ASP.NET app I use HttpWebRequest for fetching external resources which I'd like to be cached. Consider the following code: var req = WebRequest.Create("http://google.com/"); req.CachePolicy = new HttpRequestCachePolicy(HttpRequestCacheLevel.CacheIfAvailable); var resp = req.GetResponse(); Console.WriteLine(resp.IsFromCache); var answ = (new StreamReader(resp.GetResponseStream())).ReadToEnd(); Console.WriteLine(answ.Length); HttpWebRequest uses IE cache, so when I run it as normal user, data is cached to %userprofile%\Local Settings\Temporary Internet Files and next responses are read from cache. I thought that when such code is run inside ASP.NET app, data will be cached to ...\ASPNET\Local Settings\Temporary Internet Files but it is not and cache is never used. What I am doing wrong? How to force HttpWebRequest to use cache in ASP.NET environment?

  • Migrating Windows Server 2003 installation to new hardware

    - by Alex
    I have a Windows 2003 Server that I want to migrate to new hardware. All the setup and configuration was done by my predecessor. Right now I'm in a real time crunch and I just want to copy all the files and settings to the new machine. Is there an easy way to do this or do I need to manually copy all the files and add all the settings? Microsoft KB suggests "Automated System Recovery", is this the best way forward?

  • NSInvocation: object does not implement methodSignatureForSelector

    - by Sam V
    I have this weird crash that only happens when running the app on the device (doesn't happen in the Simulator). It seems like the problem surfaces out of nowhere, as I haven't changed anything on that particular class. I had the very same issue a few days ago, and I ended up fixing it by duplicating the class, renaming it, and changing the referenced class — I haven't changed a single bit of code. So I'm trying to understand why it's doing this. I've read somewhere that usually you get this console error when the object isn't a subclass of NSObject (but it is!). Here's the exact console error message: *** NSInvocation: warning: object 0x679e0 of class 'FFProximityPickerView' does not implement methodSignatureForSelector: -- trouble ahead *** NSInvocation: warning: object 0x679e0 of class 'FFProximityPickerView' does not implement doesNotRecognizeSelector: -- abort And then it crashes. I'd be very thankful for anyone who can help me on this.

  • How do Ruby and Python implement their interactive consoles?

    - by sxa
    When implementing the interpreter for my programming language I first thought of a simple console window which allows the user to enter some code which is then executed as a standalone program as a shell. But there are severe problems: If every line of code the user enters is handled as a standalone program, it has to go through the tokenizer and parser and is then just executed by the interpreter - what about functions then? How can the Python/Ruby interactive consoles (IDLE, irb) "share" the code? How is the code entered handled? Example: >> def x: >> print("Blah") >> >> x() Where is the function stored so it can be called at any time again? How can the interactive console take everything entered as obviously one program without executing everything over and over again?

  • jQuery UI dialog + WebKit + HTML response with script

    - by Anthony Koval'
    Once again I am faced with a great problem! :) So, here is the stuff: on the client side, I have a link. By clicking on it, jQuery makes a request to the server, gets response as HTML content, then popups UI dialog with that content. Here is the code of the request-function: function preview(){ $.ajax({ url: "/api/builder/", type: "post", //dataType: "html", data: {"script_tpl": $("#widget_code").text(), "widgets": $.toJSON(mwidgets), "widx": "0"}, success: function(data){ //console.log(data) $("#previewArea").dialog({ bgiframe: true, autoOpen: false, height: 600, width: 600, modal: true, buttons: { "Cancel": function() { $(this).dialog('destroy'); } } }); //console.log(data.toString()); $('#previewArea').attr("innerHTML", data.toString()); $("#previewArea").dialog("open"); }, error: function(){ console.log("shit happens"); } }) } The response (data) is: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript">var smakly_widget_sid = 0 ,widgets = [{"cols": "2","rows": "2","div_id": "smakly_widget","wid": "0","smakly_style": "small_image",}, ] </script> <script type="text/javascript" src="/media/js/smak/smakme.js"></script> </head> <body> preview <div id="smakly_widget" style="width:560px;height:550px"> </div> </body> </html> As you see, there is a script to load: smakme.js, somehow it doesn't execute in WebKit-based browsers (I tried in Safari and Chrome), but in Firefox, Internet Explorer and Opera it works as expected! Here is that script: String.prototype.format = function(){ var pattern = /\{\d+\}/g; var args = arguments; return this.replace(pattern, function(capture){ return args[capture.match(/\d+/)]; }); } var turl = "/widget" var widgetCtrl = new(function(){ this.render_widget = function (w, content){ $("#" + w.div_id).append(content); } this.build_widgets = function(){ for (var widx in widgets){ var w = widgets[widx], iurl = '{0}?sid={1}&wid={2}&w={3}&h={4}&referer=http://ya.ru&thrash={5}'.format( turl, smakly_widget_sid, w.wid, w.cols, w.rows, Math.floor(Math.random()*1000).toString()), content = $('<iframe src="{0}" width="100%" height="100%"></iframe>'.format(iurl)); this.render_widget(w, content); } } }) $(document).ready(function(){ widgetCtrl.build_widgets(); }) Is that some security issue, or anything else?

  • Help me understand Dispose() implementation code from MSDN

    - by Benny
    the following code is from MSDN: Idisposable pattern protected virtual void Dispose(bool disposing) { // If you need thread safety, use a lock around these // operations, as well as in your methods that use the resource. if (!_disposed) { if (disposing) { if (_resource != null) _resource.Dispose(); Console.WriteLine("Object disposed."); } // Indicate that the instance has been disposed. _resource = null; _disposed = true; } } why the following statement: _resource = null; _disposed = true; are not enclosed by if (disposing) statement block? for me i would probably write like this: if (disposing) { if (_resource != null) { _resource.Dispose(); _resource = null; _disposed = true; } Console.WriteLine("Object disposed."); } anything wrong with my version?

  • jQuery Ajax Methods Not Returning XHR Object

    - by Nate
    UPDATE: I haven't figured out what's going on, but this definitely seems to be a problem with my project. After creating a simple test page, I was able to verify that getJSON does in fact return an XHR object like it's supposed to. Per the stackoverflow question/answer here: Kill ajax requests using javascript using jquery. and a number of other question/answers on this site and others, the jQuery Ajax methods should return the XHR object. However, when I run the following code, request is "undefined". var request = $.getJSON(url, function(data) { console.log(data); }); console.log(request); Did I miss a change in jQuery? I'm using 1.4.4.

  • An Inaccessible JavaScript Object property - Why is Firebug showing this?

    - by Matty
    So, I'm attempting to access the content of an object and for the life of me can't figure out why I can't. I'm starting to believe that the object doesn't have the properties that Firebug indicates that it does. More likely than that I'm just not using the right syntax to access them. Give the following function: function(userData) { console.log(userData); // statement 1 console.log(userData.t_nodecontent); // statement 2 } Which generates the following FireBug output for statement 1 and unknown for statement 2. Is there something obvious that I'm overlooking in the way I'm attempting to reference the value of t_nodecontent? I'm at a loss :(

  • Scala methods ending in _=

    - by Alexey Romanov
    I seem to remember Scala treating methods ending in _= specially, so something like this: object X { var x: Int = 0; def y_=(n : Int) { x = n }} X.y = 1 should call X.y_=(1). However, in 2.8.0 RC1, I get an error message: <console>:6: error: value y is not a member of object X X.y = 1 ^ Interestingly, just trying to call the method without parentheses fails as well: scala> X.y_= 1 <console>:1: error: ';' expected but integer literal found. X.y_= 1 ^ Am I misremembering something which does actually exist or did I just invent it out of whole cloth?
