  • how do I zoom to normal text size in vs2008?

    - by gerryLowry
    I can not find any help on this issue in vs2008 help, Google, or SO. Scenario: I'm looking at a source file in vs2008 SP1; Windows 2003 Server SP2 Standard Edition, 1280x1024. The irrelevant name of this file is index.aspx. What is relevant is that the file has only 65 lines of code. The print is unreadably small--less than 4 point. It uses less than a third of the vs2008 text window vertically and less that a quarter of the vs2008 text window horizontally. It's not just index.aspx; e.g. another file with 142 lines only fills about 3/4 of the vs2008 text window vertically and less that a quarter of the vs2008 text window horizontally. Possible cause: Probably, but not certainly, I found the equivalent of zoom in/zoom out such as one finds in products like Microsoft Word. However, I've explored many vs2008 toolbars and other customization options and unfortunately I can not find out how to get myself out of this mess. Window, Reset Window Layout has no effect on the text size; my tiny text size did not change. QUESTION: how do I zoom vs2008 text size in and out and back to normal size? Thank you. Regards ~~ Gerry (Lowry)

  • C# Accepting sockets in async fasion - best practices

    - by psulek
    What is the best way to accept new sockets in async way. First way: while (!abort && listener.Server.IsBound) { acceptedSocketEvent.Reset(); listener.BeginAcceptSocket(AcceptConnection, null); bool signaled = false; do { signaled = acceptedSocketEvent.WaitOne(1000, false); } while (!signaled && !abort && listener.Server.IsBound); } where AcceptConnection should be: private void AcceptConnection(IAsyncResult ar) { // Signal the main thread to continue. acceptedSocketEvent.Set(); Socket socket = listener.EndAcceptSocket(ar); // continue to receive data and so on... .... } or Second way: listener.BeginAcceptSocket(AcceptConnection, null); while (!abort && listener.Server.IsBound) { Thread.Sleep(500); } and AcceptConnection will be: private void AcceptConnection(IAsyncResult ar) { Socket socket = listener.EndAcceptSocket(ar); // begin accepting next socket listener.BeginAcceptSocket(AcceptConnection, null); // continue to receive data and so on... .... } What is your prefered way and why?

  • Rebind dymanically created forms after jQuery ajax response

    - by Pjack
    I'm kinda new to jQuery but understand it for the most part. My problem is that when my ajax call which refreshes the entire div is done, all my dynamically created forms don't work. If you try and submit them, the event doens't work properly and just tries to do a normal form submit. I have all the other items such as links bound using the .live() which seem to work great. Just the form dies. How do I rebind the dynamically created forms after the ajax call? They all have id of formname_id. I tried to use bind but it doesn't work as below. Any help is appreciated. Here is the code jQuery(document).ready(function(){ jQuery("form[id^='commentform_']").each(function(){ var id = parseInt(this.id.replace("commentform_", "")); jQuery(this).bind('submit', function(e) { var action = jQuery('#action_' + id).attr('value'); var act_id = ('1'); jQuery.ajax({ type: "POST", url: "ajax/modify.php", data: "action="+ action +"& act_id="+ act_id, success: function(response){ jQuery('#CommentsContainer_' + id).html(response); jQuery('#commentform_' + id)[0].reset(); } }); return false; }); }); });

  • Fixing parent controller's elements after screen orientation

    - by Jonas Anderson
    I have a tab bar application with mixed orientation support for only some views. One of the child view controller shown from one of the tab's navigation controller is displayed only in Landscape mode. In order to accomplish this, I've done the view transformation for the child view as suggested here: Is there a documented way to set the iPhone orientation? The only problem I'm seeing is that after I've performed the orientation adjustment for the child controller and then readjusted orientation back to normal on its dismissal, the contents of the (parent) navigation controller is still shown with Landscape mode dimensions despite the navigation controller reporting the correct value for the interfaceOrientation. How do I ensure that view's size is reset to match the orientation without hardcoding screen dimensions? I have the following in the root navigation controller's viewWillAppear (invoked after the child controller is dismissed): - (void)viewWillAppear:(BOOL)animated { NSLog(@"viewFrame: (%2f, %2f), width: %2f, height: %2f\n", self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height); // Frame values are (0, 0) for (x,y) width: 320, height: 367 before I // displayed child controller. // Frame values are (0,0) width: 480, height: 219 after returning from child // controller -- still has the landscape dimensions NSLog(@"orientation: %d", self.interfaceOrientation); // reports portrait as expected } I've tried to invoke 'layoutIfNeeded' as well as 'setNeedsDisplay' on the view but neither of them bring the view contents into the correct display. Any suggestions would be greatly appreciated.

  • XSLT line counter - is it that hard?

    - by Mr AH
    I have cheated every time I've needed to do a line count in XSLT by using JScript, but in this case I can't do that. I simply want to write out a line counter throughout an output file. This basic example has a simple solution: <xsl:for-each select="Records/Record"> <xsl:value-of select="position()"/> </xsl:for-each> Output would be: 1 2 3 4 etc... But what if the structure is more complex with nested foreach's : <xsl:for-each select="Records/Record"> <xsl:value-of select="position()"/> <xsl:for-each select="Records/Record"> <xsl:value-of select="position()"/> </xsl:for-each> </xsl:for-each> Here, the inner foreach would just reset the counter (so you get 1, 1, 2, 3, 2, 1, 2, 3, 1, 2 etc). Does anyone know how I can output the position in the file (ie. a line count)?

  • Django repeating vars/cache issue?

    - by Mark
    I'm trying to build a better/more powerful form class for Django. It's working well, except for these sub-forms. Actually, it works perfectly right after I re-start apache, but after I refresh the page a few times, my HTML output starts to look like this: <input class="text" type="text" id="pickup_addr-pickup_addr-pickup_addr-id-pickup_addr-venue" value="" name="pickup_addr-pickup_addr-pickup_addr-pickup_addr-venue" /> The pickup_addr- part starts repeating many times. I was looking for loops around the prefix code that might have cause this to happen, but the output isn't even consistent when I refresh the page, so I think something is getting cached somewhere, but I can't even imagine how that's possible. The prefix car should be reset when the class is initialized, no? Unless it's somehow not initializing something? class Form(object): count = 0 def __init__(self, data={}, prefix='', action='', id=None, multiple=False): self.fields = {} self.subforms = {} self.data = {} self.action = action self.id = fnn(id, 'form%d' % Form.count) self.errors = [] self.valid = True if not empty(prefix) and prefix[-1:] not in ('-','_'): prefix += '-' for name, field in inspect.getmembers(self, lambda m: isinstance(m, Field)): if name[:2] == '__': continue field_name = fnn(field.name, name) field.label = fnn(field.label, humanize(field_name)) field.name = field.widget.name = prefix + field_name + ife(multiple, '[]') field.id = field.auto_id = field.widget.id = ife(field.id==None, 'id-') + prefix + fnn(field.id, field_name) + ife(multiple, Form.count) field.errors = [] val = fnn(field.widget.get_value(data), field.default) if isinstance(val, basestring): try: val = field.coerce(field.format(val)) except Exception, err: self.valid = False field.errors.append(escape_html(err)) field.val = self.data[name] = field.widget.val = val for rule in field.rules: rule.fields = self.fields rule.val = field.val rule.name = field.name self.fields[name] = field for name, form in inspect.getmembers(self, lambda m: ispropersubclass(m, Form)): if name[:2] == '__': continue self.subforms[name] = self.__dict__[name] = form(data=data, prefix='%s%s-' % (prefix, name)) Form.count += 1 Let me know if you need more code... I know it's a lot, but I just can't figure out what's causing this!

  • Ninject: Shared DI/IoC container

    - by joblot
    Hi I want to share the container across various layers in my application. I started creating a static class which initialises the container and register types in the container. public class GeneralDIModule : NinjectModule { public override void Load() { Bind().To().InSingletonScope(); } } public abstract class IoC { private static IKernel _container; public static void Initialize() { _container = new StandardKernel(new GeneralDIModule(), new ViewModelDIModule()); } public static T Get<T>() { return _container.Get<T>(); } } I noticed there is a Resolve method as well. What is the difference between Resolve and Get? In my unit tests I don’t always want every registered type in my container. Is there a way of initializing an empty container and then register types I need. I’ll be mocking types as well in unit test so I’ll have to register them as well. There is an Inject method, but it says lifecycle of instance is not managed? Could someone please set me in right way? How can I register, unregister objects and reset the container. Thanks

  • Javascript Function for related select elements onSubmit

    - by Livingston
    I am trying to create (4) Select elements within a form element. Each select element has a different number of options. So if a user click one option on Select #1 and then click another option on Select #2, after hitting submit they will be taken to www.blah.com/option1/option2 page which will display the filtered results. Or they can chose an option from all 4 select menus and be taken to option1/option2/option3/option4 page. The categories are all related .Select #1 is a category, Select #2 is a subcategory of 1, Select #3 is a subcategory of #2 and Select #4 is a subcategory of #3. A great example would be on (LINK) http://www.safavieh.com/rugs (LINK) except only four Select elements. I would also like to add the "Reset" button next to "Submit." I know I need to construct a function in my header and use onSubmit attribute within the form but other than that I am unsure of what's involved so I'm hoping someone could point me in the right direction. It's important I learn most of this for myself. Thanks for your time Livingston

  • Blackberry Keyboard Lock timeout

    - by Vernon
    I want this blackberry 9700 to "fully lock" as soon as I click the icon for the "Keyboard Lock" application. Currently I have to wait 5 to 7 seconds for the screen to go dark after each time I click the "Keyboard Lock" icon. During that time if something touches the touch pad, then the 5-7 second timer resets and you have to wait another 5 to 7 seconds for the screen to go dark and "fully lock" After it finally goes dark, touching the touch pad does not reset the timer. At that point it is "fully locked" and requires a key to be pressed. How can I get it to "fully lock" as soon as the lock icon is clicked? I want the screen to go dark immediately, and for it to require a key press to request an unlock. I have tried Options - Screen/Keyboard - Backlight Timeout ... etc ... none of that reduces the timeout for the "Keyboard Lock" application. And there does not seem to be an option screen for the "Keyboard Lock" application, that I can find. NOTE: This is occurring with BlackBerry 9700 v5.0.0.330 (Platform 5.1.0.91)

  • Expression Blend doesn't recognize command objects declared in code behind file

    - by Brian Ensink
    I have a WPF UserControl. The code behind file declares some RoutedUICommand objects which are referenced in the XAML. The application builds and runs just fine. However Expression Blend 3 cannot load the XAML in the designer and gives errors like this one: The member "ResetCameraCommand" is not recognized or accessible. The class and the member are both public. Building and rebuilding the project in Blend and restarting Blend hasn't helped. Any ideas what the problem is? Here are fragments of my XAML ... <UserControl x:Class="CAP.Visual.CameraAndLightingControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CAP.Visual;assembly=VisualApp" Height="100" Width="700"> <UserControl.CommandBindings> <CommandBinding Command="local:CameraAndLightingControl.ResetCameraCommand" Executed="ResetCamera_Executed" CanExecute="ResetCamera_CanExecute"/> </UserControl.CommandBindings> .... ... and the code behind C# namespace CAP.Visual { public partial class CameraAndLightingControl : UserControl { public readonly static RoutedUICommand ResetCameraCommand; static CameraAndLightingControl() { ResetCameraCommand = new RoutedUICommand("Reset Camera", "ResetCamera", typeof(CameraAndLightingControl)); }

  • WinForms - DateTimePicker default month selection behavior for Server 2003 vs Server 2008?

    - by Mike Loux
    Good Afternoon! Has anybody else noticed a change in the default behavior of the "next" and "previous" month arrows in the standard WinForms DateTimePicker control? I have users running on both Windows Server 2003 and Windows Server 2008 R2, and they are reporting that on 2008 (and Vista/Win7), clicking the right or left arrows on the drop-down Calendar now selects the first day of the month rather than retaining the same day like 2003 (and XP) does. I have checked this out (I have a Win7 machine) and I have confirmed this behavior. I would prefer that the behavior remain consistent whenever possible. Does anybody know what causes this and if there is a way to get around this? Is there a way to trap the arrow-click event and force the resulting date to retain the original day rather than be reset to the first of the month? I thought about seeing if there was a way to hit-test the control on a MouseUp event and determine if the arrow buttons were clicked, and then override the month value being set, but I'm not sure if that is even possible. Can anybody provide some wisdom or insight? Thanks!

  • Jboss 6 Cluster Singleton Clustered

    - by DanC
    I am trying to set up a Jboss 6 in a clustered environment, and use it to host clustered stateful singleton EJBs. So far we succesfully installed a Singleton EJB within the cluster, where different entrypoints to our application (through a website deployed on each node) point to a single environment on which the EJB is hosted (thus mantaining the state of static variables). We achieved this using the following configuration: Bean interface: @Remote public interface IUniverse { ... } Bean implementation: @Clustered @Stateful public class Universe implements IUniverse { private static Vector<String> messages = new Vector<String>(); ... } jboss-beans.xml configuration: <deployment xmlns="urn:jboss:bean-deployer:2.0"> <!-- This bean is an example of a clustered singleton --> <bean name="Universe" class="Universe"> </bean> <bean name="UniverseController" class="org.jboss.ha.singleton.HASingletonController"> <property name="HAPartition"><inject bean="HAPartition"/></property> <property name="target"><inject bean="Universe"/></property> <property name="targetStartMethod">startSingleton</property> <property name="targetStopMethod">stopSingleton</property> </bean> </deployment> The main problem for this implementation is that, after the master node (the one that contains the state of the singleton EJB) shuts down gracefuly, the Singleton's state is lost and reset to default. Please note that everything was constructed following the JBoss 5 Clustering documents, as no JBoss 6 documents were found on this subject. Any information on how to solve this problem or where to find JBoss 6 documention on clustering is appreciated.

  • Get Json and output to text file undecoded

    Hi, I want to fetch json script and write it to a txt file undecoded, exactly how it was originally. I do have a script that I use that I am modifying but unsure what to commands to use. This script decodes, which is what I want to advoid. //Get Age list($bstat,$bage,$bdata) = explode("\t",check_file('./advise/roadsnow.txt',60*2+15)); //Test Age if ( $bage > $CacheMaxAge ) { //echo "The if statement evaluated to true so get new file and reset $bage"; $bage="0"; $file = file_get_contents('http://somesite.jsontxt'); $out = (json_decode($file)); $report = wordwrap($out->mainText, 100, "\n"); //$valid = $out->validTo; //write the data to a text file called roadsnow.txt $myFile = "./advise/roadsnow.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); $stringData = $report; fwrite($fh, $stringData); } else { //echo the test evaluated to false; file is not stale so read local cache //print "we are at the read local cache"; $stringData = file_get_contents("./advise/roadsnow.txt"); } // if/else is done carry on with processing //Format file $data = $stringData

  • Using boost asio for pub/sub style tcp in a game loop

    - by unohoo
    I have been reading through the boost asio documentation for a couple of hours now, and while I think the documentation is really great, I am still left a bit confused on how to implement the system that I need. I have to stream info, from a game engine, to a list of computers over tcp. One snag is that, unlike traditional pub/sub, the computer that does the distribution of info is actually the computer that has to connect to the subscribers as well (instead of the subscribers registering with the publisher). This is done via a config file - a list of ip's/ports along with the data that they each require. The subscribers listen, but do not know the ip of the publisher. (As a side note, I'm quite new to network programming, so maybe I'm missing something .. but it's strange that I do not find much information regarding this style of "inverted" client-server model..) I am looking for suggestions for the implementation of such a system using boost asio. Of course I have to integrate the networking into an already existing engine, so with regards to that: What would be a good way to handle messages being sent to multiple computers every frame? Use async_write, call io_service.run and then reset every frame? Would having io_service.run have its own thread be better? Or should I just use threads and use blocking writes?

  • Cannot connect Nexus One Phone to Android adb

    - by appbee
    I am running Android SDK 2.2 and am trying to get the adb to connect to the Google Nexus One phone. Its a new phone, shipped straight from Google - haven't installed any apps on it yet. (I have Windows XP) Here is what I have done so far: Followed the instructions on setting up the device for development as given on the Android Developer's site: http://developer.android.com/guide/developing/device.html added android:debuggable="true" to my application manifest USB debuggable is checked on the phone downloaded the Device Drivers For Windows Revision 3 (this supports Nexus One phones) Went through the Hardware Installation wizard to install the device - the device shows up as "Android Composite ADB Interface". When I run adb devices on the shell, the device appears for a moment, then disappears. On the Eclipse console, I get the following message: [2010-11-13 11:54:42 - DeviceMonitor]Failed to start monitoring I have rebooted the pc several times, uninstalled and reinstalled the drivers several times, but I get the same error each time. As I was researching this problem, someone had recommended rebooting the phone. I am a bit confused by that - is that a soft or hard reboot? Do I just power the phone off/on and is there something more complex involved? Do I have to hard reboot it to reset to factory version - even though its brand new? Has anyone run into a similar problem? Any help on this would be great. I can't test my application on the device if the adb cannot view the device. Thanks so much in advance.

  • View transform seems to be ignored when animating on iphone. Why?

    - by heymon
    I have views that can be rotated, scaled and moved around the screen. I want the view to resize and be orthogonal when the user double tap's the view to edit the textview within. The code is below. Somewhere the transform is getting reset. The NSLog statement below prints the identity transform, but a print of the transform when the animation is complete in transitionDidStop reveals that the transform is what it was before I thought I set it to identity. The view resizes, but it acts like the transform was never set to identity? Any ideas/pointers? originalBounds = self.bounds; originalCenter = self.center; originalTransform = self.transform; r = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width - 70, 450); [UIView beginAnimations: nil context: NULL]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @selector(transitionDidStop:finished:context:)]; self.transform = CGAffineTransformIdentity; NSLog(@"%@ after set", NSStringFromCGAffineTransform([self transform])); [self setBounds: r]; [self setCenter: p]; [self setAlpha: 1.0]; [UIView commitAnimations]; [textView becomeFirstResponder];

  • IKImageView, Buttons work intermittently in 10.5 but ok in 10.6

    - by markhunte
    Hi all, In IB,I have connected some buttons to a IKImageView. Using its received Action 'ZoomIn:', 'ZoomOut:','ZoomImageToActualSize:' When I build for 10.6 I have no issues these work as expected. But in 10.5 (ppc), they sometimes work as expected and sometimes do not. I have even tried it programatically. But I get the same results. It is intermittent with each build after I have made some small change in IB that I need. But not changes that should affect how the view acts. The only buttons that seem to work through out are 'ZoomImageToFit' and the rotate ones. When the do not work as expected, I see no change to the current image in the view, but when my app (/s, I have had this issue before in different apps) changes the image The view reflects the last request from a button. So for example when it does not work. An image is displayed, I click the 'ZoomImageToActualSize:' button, nothing happens. I load a new image and it is displayed at Actual size. Example when it does work. An image is displayed, I click the 'ZoomImageToActualSize:' button, It is displayed at Actual size. By the way, I know I can reset the view default , before I load a new image. Also if I run the 10.5 app in 10.6, it works ok, but as above I get intermittent results with the same build on multible 10.5 machines. Does anyone know what is going on, is this a known bug? Thanks for any help. MH

  • event listener says NetStream.Play.Start but I see no video

    I'm trying to test out the Adobe Media Server, and I'm following some tutorials in order to stream a video. I have a NetConnection which successfully connects to the application on the server, then I have the code below. It looks like it's supposed to play a video, but it doesn't. It creates the video object as a black square in the top left corner, and the event.info.code says NetStream.Play.Start, but I don't see the video playing. case "NetConnection.Connect.Success": var v:Video = new Video(); v.width=200; v.height=200; v.x=0; v.y=0; v.visible=true; v.opaqueBackground=false; stage.addChild(v); var ns:NetStream = new NetStream(nc); ns.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler); v.attachNetStream(ns); ns.play("mp4:polymorphics.f4v"); I can also try ns.play("rtmp://localhost/vod/mp4:tests/polymorphics.f4v"); but that gives me a Stream Not Found error The lines that begin with "ns" means that they're generated by my NetStream listener, as opposed to my NetConnection listener.

  • Is there a way to increase the efficiency of shared_ptr by storing the reference count inside the co

    - by BillyONeal
    Hello everyone :) This is becoming a common pattern in my code, for when I need to manage an object that needs to be noncopyable because either A. it is "heavy" or B. it is an operating system resource, such as a critical section: class Resource; class Implementation : public boost::noncopyable { friend class Resource; HANDLE someData; Implementation(HANDLE input) : someData(input) {}; void SomeMethodThatActsOnHandle() { //Do stuff }; public: ~Implementation() { FreeHandle(someData) }; }; class Resource { boost::shared_ptr<Implementation> impl; public: Resource(int argA) explicit { HANDLE handle = SomeLegacyCApiThatMakesSomething(argA); if (handle == INVALID_HANDLE_VALUE) throw SomeTypeOfException(); impl.reset(new Implementation(handle)); }; void SomeMethodThatActsOnTheResource() { impl->SomeMethodThatActsOnTheHandle(); }; }; This way, shared_ptr takes care of the reference counting headaches, allowing Resource to be copyable, even though the underlying handle should only be closed once all references to it are destroyed. However, it seems like we could save the overhead of allocating shared_ptr's reference counts and such separately if we could move that data inside Implementation somehow, like boost's intrusive containers do. If this is making the premature optimization hackles nag some people, I actually agree that I don't need this for my current project. But I'm curious if it is possible.

  • Socket Read In Multi-Threaded Application Returns Zero Bytes or EINTR (-1)

    - by user309670
    Hi. Am a c-coder for a while now - neither a newbie nor an expert. Now, I have a certain daemoned application in C on a PPC Linux. I use PHP's socket_connect as a client to connect to this service locally. The server uses epoll for concurrent connections via a Unix socket. A user submitted string is parsed for certain characters/words using strstr() and if found, spawns 4 joinable threads to different websites simultaneously. I use socket, connect, write and read, to interact with the said webservers via TCP on port 80 in each thread. All connections and writes seems successful. Reads to the webserver sockets fail however, with either (A) all 3 threads seem to hang, and only one thread returns -1 and errno is set to 104. The responding thread takes like 10 minutes - an eternity long:-(. *I read somewhere that the 104 (is EINTR) suggests that ...'the connection was reset by peer', or (B) 0 bytes from 3 threads, and only 1 of the 4 threads actually returns some data. Isn't the socket read/write thread-safe? Otherwise, use thread-safe (and reentrant) libc functions such as strtok_r, gethostbyname_r, etc. *I doubt that the said webhosts are actually resetting the connection, because when I run a single-threaded standalone (everything else equal) all things works perfectly right. There's a second problem too (oops), I can't write back to the client who connect to my epoll-ed Unix socket. My daemon application will hang and hog CPU 100% for ever. Yet nothing is written to the clients end. Am sure the client (a very typical PHP socket application) hasn't closed the connection whenever this is happening - no error(s) detected either. I cannot figure-out whatever is wrong even with Valgrind or GDB

  • Developing ASP.Net User Control to be imported to SharePoint MOSS 2007

    - by Don Kirkham
    Apologies if this has been answered, but I could not find a similar question: I am developing a webpart for MOSS 2007. I am using WSPBuilder to built a visual webpart (ascx) and everything works fine, but the development/debug cycle is just painfully slow, so I'd like to know if it is possible (without being too painful) to develop the user control faster using an .Net Web Application project with all of the nice F5 debugging, then import the final product into my SharePoint visual webpart. The user control interacts with a LOB system (SQL) and does not reference the SharePoint API at all. (The reason I am building this as a webpart is because I don't need another web app to run this one page, so putting it into a webpart on a new webpart page on my existing site is the best solution IMO.) I would obviously need to import (reference?) my data access classes into my "temp" web app, but think that would not be too much trouble. I realize this will be extra effort to get this set up, but am thinking the payoff will be reduced development time of the actual user control using a little web application vs having to use the compile/build WSP/deploy WSP/reset ISS/test/make a change/repeat cycle that MOSS requires. (I guess SP2010/VS2010 has spoiled me with the native SharePoint tools available.)

  • Are .NET 4.0 Runtime slower than .NET 2.0 Runtime?

    After I upgraded my projects to .NET 4.0 (With VS2010) I realized than they run slower than they were in .NET 2.0 (VS2008). So i decided to benchmark a simple console application in both VS2008 & VS2010 with various Target Frameworks: using System; using System.Diagnostics; using System.Reflection; namespace RuntimePerfTest { class Program { static void Main(string[] args) { Console.WriteLine(Assembly.GetCallingAssembly().ImageRuntimeVersion); Stopwatch sw = new Stopwatch(); while (true) { sw.Reset(); sw.Start(); for (int i = 0; i < 1000000000; i++) { } TimeSpan elapsed = sw.Elapsed; Console.WriteLine(elapsed); } } } } Here is the results: VS2008 Target Framework 2.0: ~0.25 seconds Target Framework 3.0: ~0.25 seconds Target Framework 3.5: ~0.25 seconds VS2010 Target Framework 2.0: ~3.8 seconds Target Framework 3.0: ~3.8 seconds Target Framework 3.5: ~1.51 seconds Target Framework 3.5 Client Profile: ~3.8 seconds Target Framework 4.0: ~1.01 seconds Target Framework 4.0 Client Profile: ~1.01 seconds My initial conclusion is obviously that programs compiled with VS2008 working faster than programs compiled with VS2010. Can anyone explain those performance changes between VS2008 and VS2010? and between different Target Frameworks inside VS2010 itself?

  • Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work. Wh

    - by Kevin
    I'm just playing around with some code. I create an Activity and simply do something like this: long lo = currentTimeMillis(); System.out.println(lo); lo *= 3; System.out.println(lo); SystemClock.setCurrentTimeMillis(lo); System.out.println( currentTimeMillis() ); Yes, in my AndroidManifest.xml, I've added: <uses-permission android:name="android.permission.SET_TIME"></uses-permission> <uses-permission android:name="android.permission.SET_TIME_ZONE"></uses-permission> Nothing changes. The SystemClock is never reset...it just keeps on ticking. The error that I'm getting just says that the permission "SET_TIME" was not granted to the program. Protection level 3. The permissions are there...and in the API for 2.2 it says that this feature is supported now. I have no idea what I'm doing wrong. If android.content.Intent; comes into play, please explain. I don't really understand what the idea behind intents! Thanks for any help!

  • git changes modification time of files

    - by tanascius
    In the GitFaq I can read, that Git sets the current time as the timestamp on every file it modifies, but only those. However, I tried this command sequence (EDIT: added complete command sequence) $ git init test && cd test Initialized empty Git repository in d:/test/.git/ exxxxxxx@wxxxxxxx /d/test (master) $ touch filea fileb exxxxxxx@wxxxxxxx /d/test (master) $ git add . exxxxxxx@wxxxxxxx /d/test (master) $ git commit -m "first commit" [master (root-commit) fcaf171] first commit 0 files changed, 0 insertions(+), 0 deletions(-) create mode 100644 filea create mode 100644 fileb exxxxxxx@wxxxxxxx /d/test (master) $ ls -l > filea exxxxxxx@wxxxxxxx /d/test (master) $ touch fileb -t 200912301000 exxxxxxx@wxxxxxxx /d/test (master) $ ls -l total 1 -rw-r--r-- 1 exxxxxxx Administ 132 Feb 12 18:36 filea -rw-r--r-- 1 exxxxxxx Administ 0 Dec 30 10:00 fileb exxxxxxx@wxxxxxxx /d/test (master) $ git status -a warning: LF will be replaced by CRLF in filea # On branch master warning: LF will be replaced by CRLF in filea # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # modified: filea # exxxxxxx@wxxxxxxx /d/test (master) $ git checkout . exxxxxxx@wxxxxxxx /d/test (master) $ ls -l total 0 -rw-r--r-- 1 exxxxxxx Administ 0 Feb 12 18:36 filea -rw-r--r-- 1 exxxxxxx Administ 0 Feb 12 18:36 fileb Now my question: Why did git change the timestamp of file fileb? I'd expect the timestamp to be unchanged. Are my commands causing a problem? Maybe it is possible to do something like a git checkout . --modified instead? I am using git version 1.6.5.1.1367.gcd48 under mingw32/windows xp.

  • template specialization of a auto_ptr<T>

    - by Chris Kaminski
    Maybe I'm overcomplicating things, but then again, I do sort of like clean interfaces. Let's say I want a specialization of auto_ptr for an fstream - I want a default fstream for the generic case, but allow a replacement pointer? tempate <> class auto_ptr<fstream> static fstream myfStream; fstream* ptr; public: auto_ptr() { // set ptr to &myfStream; } reset(fstream* newPtr) { // free old ptr if not the static one. ptr = newPtr }; } Would you consider something different or more elegant? And how would you keep something like the above from propagating outside this particular compilation unit? [The actual template is a boost::scoped_ptr.] EDIT: It's a contrived example. Ignore the fstream - it's about providing a default instance of object for an auto_ptr. I may not want to provide a specialized instance, but would like to keep the auto_ptr semantics for this static default object. class UserClass { public: auto_ptr<fstream> ptr; UserClass() { } } I may not provide an dynamic object at construction time - I still want it to have a meaningful default. Since I'm not looking at ownership-transfer semantics, it really shouldn't matter that my pointer class is pointing to a statically allocated object, no?
