  • ASP.NET cached aspx page & IIS logs

    - by Vishal Seth
    Hi guys, Is there any way to find out if ASP.Net runtime has served a cached copy of ASPX page or actually went through the page life cycle? Here is my problem: I'm seeing many entries in my IIS log files that were served successfully (200 OK). I've a corresponding logging code (Log4Net API) in the Session_Start and Application_BeginRequest() events that is logging every request to my DB with more details. I'm not seeing any corresponding entries in my SQL DB for some cases that should have been created by Log4Net code. Are there any logs available to find out if a cached copy was served by .NET worker process? Moreover, if my logging code would throw an exception, won't that show up as 500 in IIS logs? The code is on Windows 2008 Server, IIS 7.

  • SQL Server: What locale should be used to format numeric values into SQL Server format?

    - by Ian Boyd
    It seems that SQL Server does not accept numbers formatted using any particular locale. It also doesn't support locales that have digits other than 0-9. For example, if the current locale is bengali, then the number 123456789 would come out as "?????????". And that's just the digits, nevermind what the digit grouping would be. But the same problem happens for numbers in the Invariant locale, which formats numbers as "123,456,789", which SQL Server won't accept. Is there a culture that matches what SQL Server accepts for numeric values? Or will i have to create some custom "sql server" culture, generating rules for that culture myself from lower level formatting routines? If i was in .NET (which i'm not), i could peruse the Standard Numeric Format strings. Of the format codes available in .NET: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF Only 6 accept all numeric types: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF And of those only 2 generate string representations, in the en-US locale anyway, that would be accepted by SQL Server: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF Of the remaining two, fixed is dependant on the locale's digits, rather than the number being used, leaving General g format: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF And i can't even say for certain that the g format won't add digit groupings (e.g. 1,234). Is there a locale that formats numbers in the way SQL Server expects? Is there a .NET format code? A java format code? A Delphi format code? A VB format code? A stdio format code? latin-numeral-digits

  • Hot deploy on Heroku with no downtime

    - by zetarun
    A bad side of pushing to Heroku is that I must push the code (and the server restarts automatically) before running my db migrations. This can obviously cause some 500 errors on users navigating the website having the new code without the new tables/attributes: the solution proposed by Heroku is to use the maintenance mode, but I want a way with no downside letting my webapp running everytime! Is there a way? For example with Capistrano: I prepare the code to deploy in a new dir I run (backward) migrations and the old code continue to work perfectly I swith mongrel instance to the new dir and restart the server ...and I have no downtime!

  • How the simples GUI countdown is supposed to work?

    - by Roman
    I am trying to write the simples GUI countdown. I found in Internet some code but it is already too fancy for me. I am trying to keep it as simple as possible. So, I just want to have a window saying "You have 10 second left". The number of second should decrease every second from 10 to 0. I wrote a code. And I think I am close to the working solution. But I still missing something. Could you pleas help me to find out what is wrong? Here is my code: import javax.swing.*; public class Countdown { static JLabel label; // Method which defines the appearance of the window. private static void showGUI() { JFrame frame = new JFrame("Simple Countdown"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JLabel label = new JLabel("Some Text"); frame.add(label); frame.pack(); frame.setVisible(true); } // Define a new thread in which the countdown is counting down. static Thread counter = new Thread() { public void run() { for (int i=10; i>0; i=i-1) { updateGUI(i,label); try {Thread.sleep(1000);} catch(InterruptedException e) {}; } } }; // A method which updates GUI (sets a new value of JLabel). private static void updateGUI(final int i, final JLabel label) { SwingUtilities.invokeLater(new Runnable(i,label) { public Runnable(int i, JLabel label) { this.i = i; this.label = label; } public void run() { label.setText("You have " + i + " seconds."); } }); } // The main method (entry point). public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { showGUI(); //counter.start(); } }); //counter.start(); } } And I have several concrete question about this code: Where should I place the counter.start();? (In my code I put it on 2 places. Which one is correct?) Why compiler complains about the constructor for Runnable? It says that I have an invalid method declaration and I need to specify the returned type. ADDED: I made the suggested corrections. And then I execute the code and get: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at Worker.run(Worker.java:12) In the Worker.java in the line 12 I have: label.setText("You have " + i + " seconds.");.

  • Giving another object a NSManagedObject

    - by Wayfarer
    Alright, so I'm running into an issue with my code. What I have done is subclassed UIButton so I can give it some more infomormation that pertain to my code. I have been able to create the buttons and they work great. Capiche. However, one of the things I want my subclass to hold is a reference to a NSMangedObject. I have this code in my header file: @interface ButtonSubclass : UIButton { NSManagedObjectContext *context; NSManagedObject *player; } @property (nonatomic, retain) NSManagedObject *player; @property (nonatomic, retain) NSManagedObjectContext *context; - (id)initWithFrame:(CGRect)frame andTitle:(NSString*)title; //- (void)setPlayer:(NSManagedObject *)aPlayer; @end As you can see, it has a instance variable to the NSMangedobject I want it to hold (as well as the Context). But for the life of me, I can't get it to hold that NSManagedObject. I run both the @synthesize methods in the Implementation file. @synthesize context; @synthesize player; So I'm not sure what I'm doing wrong. This is how I create my button: ButtonSubclass *playerButton = [[ButtonSubclass alloc] initWithFrame:frame andTitle:@"20"]; //works playerButton.context = self.context; //works playerButton.player = [players objectAtIndex:i]; //FAILS And I have initilaized the players array earlier, where I get the objects. Another weird thing is that when it gets to this spot in the code, the app crashes (woot) and the the console output stops. It doesn't give me any error, and notification at all that the app has crashed. It just... stops. So I don't even know what the error is that is crashing the code, besides it has to do with that line up there setting the "player" variable. Thoughts and ideas? I'd love your wisdom!

  • When using Clipboard, Toolkit and Transferable, I get an error objecting to image width and height

  • How change Subversion's default binary mime-type?

    - by lamcro
    Subversion sets a binary file's svn:mime-type property to application/octet-stream by default. I need to change this default to some other mime-type. When I import for the first time this code, I would like Subversion to set mime-type to the one I choose. The reason is that my code base contains code in binary files (proprietary format), and I have the applications necessary to emulate diff and diff3 for these. But Subversion does not let me due to their default mime-type. Please note: There is no default extension (*.jar, *.py, etc) for these code files. Some files don't even have an extension. So configuring mime-type by file extension is not possible.

  • Reasons to learn MSIL

    - by mannu
    Hi, Learning MSIL is fun and all that. Understanding what is going on "under the hood" can in many ways improve how you write your code performance-wise. However, the IL that is produced by the compiler is quite verbose and does not tell the whole story since JIT will optimize away a lot of the code. I, personally, have had good use of my very basic IL understanding when I've had to make a small fix in an assembly I do not have the source code for. But, I could as well have used Reflector to generate C# code. I would like to know if you've ever had good use of MSIL understanding and/or why you think it is worth learning it (except for the fun in it, of course). I'd also like to know if you think one should not learn it and why.

  • ASP.NET UpdateProgress template does not disapper when panel in UpdatePanel has display set to none

    I am using very simple code where I have a update panel with some panels inside and a submit button. On submit, i hide one of the panels using this code: panel.Style.Add("display", "none"); I am also using a UpdateProgress which works great in all but this case. When i set the display to none using this code, the UpdateProgress template does not disappear! remove the line, all is well .... No idea why...

  • The fastest way to iterate through a collection of objects

    - by Trev
    Hello all, First to give you some background: I have some research code which performs a Monte Carlo simulation, essential what happens is I iterate through a collection of objects, compute a number of vectors from their surface then for each vector I iterate through the collection of objects again to see if the vector hits another object (similar to ray tracing). The pseudo code would look something like this for each object { for a number of vectors { do some computations for each object { check if vector intersects } } } As the number of objects can be quite large and the amount of rays is even larger I thought it would be wise to optimise how I iterate through the collection of objects. I created some test code which tests arrays, lists and vectors and for my first test cases found that vectors iterators were around twice as fast as arrays however when I implemented a vector in my code in was somewhat slower than the array I was using before. So I went back to the test code and increased the complexity of the object function each loop was calling (a dummy function equivalent to 'check if vector intersects') and I found that when the complexity of the function increases the execution time gap between arrays and vectors reduces until eventually the array was quicker. Does anyone know why this occurs? It seems strange that execution time inside the loop should effect the outer loop run time.

  • Do I have to create a static library to test my application?

    - by Christopher Gateley
    I'm just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the question is applicable to most other testing frameworks and to languages other than C/C++. My general approach so far has been to do either one of three things: Write the majority of the application in a static library, then create two executables. One executable is the application itself, while the other is the test runner with all of the tests. Both link to the static library. Embed the testing code directly into the application itself, and enable or disable the testing code using compiler flags. This is probably the best approach I've used so far, but clutters up the code a bit. Embed the testing code directly into the application itself, and, given certain command-line switches either run the application itself or run the tests embedded in the application. None of these solutions are particularly elegant... How do you do it?

  • Testing Broadcasting and receiving messages

    - by Avik
    Guys am having some difficulty figuring this out: I am trying to test whether the code(in c#) to broadcast a message and receiving the message works: The code to send the datagram(in this case its the hostname) is: public partial class Form1 : Form { String hostName; byte[] hostBuffer = new byte[1024]; public Form1() { InitializeComponent(); StartNotification(); } public void StartNotification() { IPEndPoint notifyIP = new IPEndPoint(IPAddress.Broadcast, 6000); hostName = Dns.GetHostName(); hostBuffer = Encoding.ASCII.GetBytes(hostName); UdpClient newUdpClient = new UdpClient(); newUdpClient.Send(hostBuffer, hostBuffer.Length, notifyIP); } } And the code to receive the datagram is: public partial class Form1 : Form { byte[] receivedNotification = new byte[1024]; String notificationReceived; StringBuilder listBox; UdpClient udpServer; IPEndPoint remoteEndPoint; public Form1() { InitializeComponent(); udpServer = new UdpClient(new IPEndPoint(IPAddress.Any, 1234)); remoteEndPoint=null; startUdpListener1(); } public void startUdpListener1() { receivedNotification = udpServer.Receive(ref remoteEndPoint); notificationReceived = Encoding.ASCII.GetString(receivedNotification); listBox = new StringBuilder(this.listBox1.Text); listBox.AppendLine(notificationReceived); this.listBox1.Items.Add(listBox.ToString()); } } For the reception of the code I have a form that has only a listbox(listBox1). The problem here is that when i execute the code to receive, the program runs but the form isnt visible. However when I comment the function call( startUdpListener1() ), the purpose isnt served but the form is visible. Whats going wrong?

  • Get Function Pointer to function in a shared library I didn't directly load

    - by bdk
    My Linux application (A) links against a Third Party shared Library (B) which I don't have source code to. This library makes use of another third party shared library that I don't have source code to (C). I believe that (B) uses dlopen to access (C) instead of directly linking. My reasoning for this is that 'ldd' on (B) does not show (C) and objdump -X (B) shows references to dlopen/dlclose/dlsym. My requirement is that I need to in my code for (A) get a function pointer to a function foo() located in (C). Normally I'd use dlsym for this, but I need to pass it the handle returned from dlopen which I don't have since (B) does not expose this. - For the larger context: I need to modify the function in (C) such that everytime it calls its helper function bar() (also located in (C)), it also calls a function with the same signature located in (A) with the same parameters (Basically inject my code into the codepath of (C) foo()-bar(). I believe I've found a way to accomplish this using gdb, but in order to port my gdb command list, but I'm stuck on the step of getting the function pointer. I'm also open to alternatives to accomplish the same task rather than the exact problem as stated above Edit: After writing this I realized I can probably just do another dlopen on the file in my code and the symbols returned via dlsym on that handle should be the same as received via the original dlopen, If I'm reading the dlopen man page correctly. However I'm still interested in advice or assistance with the my larger context, If theres a better way to go about this

  • document.onclick settimeout function javascript help

    - by Jamex
    Hi, I have a document.onclick function that I would like to have a delay. I can't seem to get the syntax right. my original code is <script type="text/javascript"> document.onclick=check; function check(e){do something} I tried the below, but that code is incorrect, the function did not execute and nothing happened. <script type="text/javascript"> document.onclick=setTimeout("check", 1000); function check(e){do something} I tried the next set, the function got executed, but no delay. <script type="text/javascript"> setTimeout(document.onclick=check, 1000); function check(e){do something} what is the correct syntax for this code. TIA Edit: The solutions were all good, my problem was that I use the function check to obtain the id of the element being clicked on. But after the delay, there is no "memory" of what was being clicked on, so the rest of the function does not get executed. Jimr wrote the short code to preserve clicked event. The code that is working is // Delay execution of event handler function "f" by "time" ms. document.onclick = makeDelayedHandler(check, 250); function makeDelayedHandler( f, time) { return function( e ) {setTimeout(function() {f( e );}, time ); }; } function check(e){ var click = (e && e.target) || (event && event.srcElement); . . . Thank you all.

  • refactoring in iSeries (RPG), is it realistic

    - by albert green
    Implementing agile in projects requires the ability to do refactoring. It is not really a must, but code refactoring has proven to be a good engineering practice. In an agile (Scrum) project on the iSeries platform, which requires development (new code and modifications to legacy code) in RPG, RPG LE, is it possible to implement refactoring? If so what are the techniques to do it? If someone who has tried it could share their experience or just point to references, I would greatly appreciate it.

    Here is my scenario: i have a parent web page, in my javascript code I open a new window. This new window is a server-side aspx page. This child page needs to save some data in the database, and after saving it returns an ID. Now, I need to pass this ID from the child server page to the parent's javascript. Essentially I need the child server code to trigger: 1) return the value to the javascript code of the parent page 2) close itself What would be the acceptable way to do it?

Is it possible to reliably unit test any of these implementations? I don't see a mock implementation working, because then I'm only testing the mock code and not the actual code.

  • C++/CLI Mixed Mode DLL Creation

    - by Adam Haile
    I've got a native C++ DLL that I would like to have a C++/CLI wrapper layer for. From what I understood, if you simple added a C++/CLI class to the project, VS would compile as mixed mode, but I was apparently wrong as VS doesn't seem to be even touching the managed code. So, given a pre-existing native code-base what exactly, step-by-step, do you need to do to create a mixed mode DLL, so that I can can link into that code from any .NET language? *I need to do this because my native code uses C++ classes that I cannot P/Invoke into.

  • Loading url with cyrillic symbols

    - by Ockonal
    Hi guys, I have to load some url with cyrillic symbols. My script should work with this: http://wincode.org/%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5/ If I'll use this in browser it would replaced into normal symbols, but urllib code fails with 404 error. How to decode correctly this url? When I'm using that url directly in code, like address = 'that address', it works perfect. But I used parsing page for getting this url. I have a list of urls which contents cyrillic. Maybe they have uncorrect encoding? Here is more code: requestData = urllib2.Request( %SOME_ADDRESS%, None, {"User-Agent": user_agent}) requestHandler = pageHandler.open(requestData) pageData = requestHandler.read().decode('utf-8') soupHandler = BeautifulSoup(pageData) topicLinks = [] for postBlock in soupHandler.findAll('a', href=re.compile('%SOME_REGEXP%')): topicLinks.append(postBlock['href']) postAddress = choice(topicLinks) postRequestData = urllib2.Request(postAddress, None, {"User-Agent": user_agent}) postHandler = pageHandler.open(postRequestData) postData = postHandler.read() File "/usr/lib/python2.6/urllib2.py", line 518, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 404: Not Found
