  • Is there any reason for a blocking call to winsock send() function on Vista to return immediately ?

    - by ivymike
    Hi All, Is there any reason for a blocking call to winsock's send() function on Vista to return immediately ? It works with expected delay on XP and below. I'm wondering if this has got anything to do with auto-tuning feature of Vista. Code: char *pBuffer; // pointer to data int bytes; // total size int i = 0, j=0; while (i < bytes) { j = send(m_sock, pBuffer+i, bytes-i, 0); i+=j; } Thanks, Pavan

  • Visaul Studio 2010, TlbImp generates .net 4.0 interops in 2.0 projects

    - by DJScrib
    In a C# project we add a reference to a COM object via the Add References setup pointing to a COM object which results in the IDE auto-generating the interop assembly. So this is fine and good, but we are building based on .net 3.5 SP1 aka CLR 2.0, and the generated interops are using the 4.0 CLR making them incompatiable. Is there a way to prevent this? I assume the other option is in our build script to try using tlbimp.exe with the /references parameter? to point to mscorlib v2.0? Anyhow, I'm hoping there's a flag somewhere to allow this.

  • Detect all changes to a <input type="text"> (immediately) using JQuery

    - by Dustin Boswell
    There are many ways the value of a <input type="text"> can change, including: keypresses copy/paste modified with JavaScript auto-completed by browser or a toolbar I want my JavaScript function to be called (with the current input value) any time it changes. And I want it to be called right away, not just when the input loses focus. I'm looking for the cleanest and most robust way to do this across all browsers (using jQuery preferably). Example use case: On the Twitter Signup page, the username field's value gets shown in the url "http://twitter/username" below it.

  • How can I center a box of unknown width in CSS?

    - by NXTBoy
    I have this html: <div class="object-box"> <img ... /> <span class="caption">This is the caption</span> </div> Which is accompanied with this CSS: .object-box .caption, .object-box img { display: block; } .object-box { border: 1px solid; } I would like the surrounding div to shrink-wrap to its contents. I can achieve this by using float: ... or display: inline-block. However, I'd also like it to be centered on the page, using margin: auto. The two approaches don't seem to be compatible. Is it possible to create such a shrink-wrapped, centered container, without adding a wrapper element?

  • Is there a good web-based project management app with scheduling?

    - by Andykiteman
    Ideally something as intuitive as basecamp, with good usability and accessibility. The best I've seen is huddle.net but it's still weak in several areas. Must have: Projects - ability to add people & tasks and schedule tasks to people Calendar - showing when people are busy or available Role based access - Admins and non-admins History - ability to look back at all history Anyone seen a product that's worth a look? Clarification: Must be hosted i.e. not require my own hardware or IT staff I'm looking for an app to schedule people with specific tasks at specific times and monitor the outcomes. I'm already using Mingle (for stories), Basecamp (to run the business) and Exceptional (to track bugs). I'm not looking for a bug-tracking system or a story management application (I already looked at VersionOne, but chose Mingle due to it's nicer UI) My response to the answer being auto-selected: I still don't feel the answer (chosen for me) is the correct one. It's a useful list but little more, and doesn't provide the solution I was seeking.

  • How can I make the boostrap js carousel automatically cycle as soon as the page loads?

    - by Jonathan Larkin
    Using bootstrap.js version 2.02 I'm trying to get the Twitter Bootstrap Carousel to automatically cycle as soon as someone visits my site. Right now, the auto cycling works only after you click one of the cycle buttons at least once. I want the carousel to begin cycling at the interval right away. Does anyone know how to do this? My site is hotairraccoon.com You'll see how after you click the carousel once, it begins to cycle every 5 seconds or so, but I don't want the click to be required to reveal carousel content. Thanks!

  • How does Facebook codes their Cropping tool?

    - by Trip
    I ask this because I am currently trying to work out my own technique, and there are huge strategic hangups for the entire site when your begin this. Of them are: Using jCrop and rMagick, it takes up a huge amount of processing ( to which I have backgrounded ). Because I have it backgrounded, I must by ajax develop a feature that auto-updates every five seconds to check when the backgrounding is done. Has anyone accomplished this with their sites? If so, what are some creative techniques you came across to keep the processing streamline, and the users happy?

  • Using CSS to positon text after an image

    - by Charles L
    I've trying to do something that I'm sure is simple, but I can't do it. All I want to do is have an image and then some text after that image, and be able to control accurately the amount of space between the image and the text. Here's my code: http://pastebin.com/fx17XUaR I couldn't work out how to paste it in here directly. In my style sheet, wrap has these attributes: .wrap { //text-align: left; width: 1100px; height: 870px; background-color: white; color: black; padding: 10px; margin: auto; I want my text to look like this directly below the image: Username Age Location Currently, I just add loads of break tags to control where I have the text, but that's messy and there must be a better way. Thanks in advance for any help.

Note: treeView1.SelectedNode.EnsureVisible(); is not available in asp.net need another way.

  • Automatic VisualState Manager in Silverlight

    - by Matt
    If you create a simple button and then choose Edit Template - Edit a Copy, Blend will automatically generate a style area, along with all the button states (MouseEnter, MouseLeave, Pressed, etc). No where in the code behind or auto generated style area does it say that on a "MouseOver" event, change the state to "MouseOver", but it still manages to work! Is the only way to change a button's state have to be done the code behind using the VisualStateManager.GoToState method, or can you change it much like CSS does (a:hover) using the VisualStateManager? From my experience, setting just doesn't seem to do the trick.

  • Should i really use integer primary IDs [sql]

    - by arthurprs
    For example, i always generate an auto-increment field for the users table, but i also specifies an UNIQUE index on their usernames. There is situations that i first need to get the userId for a given username and then execute the desired query. Or use a JOIN in the desired query. It's 2 trips to the database or a JOIN vs. a varchar index The above is just an example There is a real performance benefit on INT over small VARCHAR indexes? Thanks in advance!

  • Given a document select a relevant snippet.

    - by BCS
    When I ask a question here, the tool tips for the question returned by the auto search given the first little bit of the question, but a decent percentage of them don't give any text that is any more useful for understanding the question than the title. Does anyone have an idea about how to make a filter to trim out useless bits of a question? My first idea is to trim any leading sentences that contain only words in some list (for instance, stop words, plus words from the title, plus words from the SO corpus that have very weak correlation with tags, that is that are equally likely to occur in any question regardless of it's tags)

  • Interface with generic parameters- can't get it to compile

    - by user997112
    I have an interface like so: public interface MyInterface<E extends Something1> { public void meth1(MyClass1<E> x); } and I have a subclass whose superclass implements the above interface: public class MyClass2<E extends Something1> extends Superclass{ public MyClass2(){ } public void meth1(MyClass1 x) { // TODO Auto-generated method stub } } superclass: public abstract class Superclass<E extends Something1> implements MyInterface{ MyClass1<E> x; protected E y; public Superclass(){ } } the problem is that the parameter for meth1() is supposed to be generic. If I do MyClass1 it doesn't like it and the only way I can get it to compile is by leaving out generic parameters- which feels wrong. What's going wrong?

  • Possible to convert list of #defines into strings (C++)

    - by brandonC
    Suppose I have a list of #defines in a header file for an external library. These #defines represent error codes returned from functions. I want to write a conversion function that can take as an input an error code and return as an output a string literal representing the actual #define name. As an example, if I have #define NO_ERROR 0 #define ONE_KIND_OF_ERROR 1 #define ANOTHER_KIND_OF_ERROR 2 I would like a function to be able to called like int errorCode = doSomeLibraryFunction(); if (errorCode) writeToLog(convertToString(errorCode)); And have convertToString() be able to auto-convert that error code without being a giant switch-case looking like const char* convertToString(int errorCode) { switch (errorCode) { case NO_ERROR: return "NO_ERROR"; case ONE_KIND_OF_ERROR: return "ONE_KIND_OF_ERROR"; ... ... ... I have a feeling that if this is possible, it would be possible using templates and metaprogramming, but that would only work the error codes were actually a type and not a bunch of processor macros. Thanks

  • Google App Engine datastore-primary key

    - by megala
    Hi, I've created a table in the Google App Engine Datastore. It contains the following FIELDS(GROUPNAME,GROUPID,GROUPDESC). How do I set GROUPID as the primary key? My code is as follows: @Entity @Table(name="group" , schema="PUBLIC") public class Creategroup { @Basic private String groupname; @Basic private String groupid; @Basic private String groupdesc; public void setGroupname(String groupname) { this.groupname = groupname; } public String getGroupname() { return groupname; } public void setGroupid(String groupid) { this.groupid = groupid; } public String getGroupid() { return groupid; } public void setGroupdesc(String groupdesc) { this.groupdesc = groupdesc; } public String getGroupdesc() { return groupdesc; } public Creategroup(String groupname, String groupid, String groupdesc ) { // TODO Auto-generated constructor stub this.groupname = groupname; this.groupid = groupid; this.groupdesc = groupdesc; } }

  • Combining packages from different projects into a single project in eclipse

    - by primal
    Hi, As part of the Android application I am developing in eclipse, I need to combine two packages from different projects into a single project. I tried copying the files in the package of the second project under the src folder of the first folder and copied other files required for second package into the res folder of the first project. But the auto-generated Java files i.e R.java doesn't get updated on copying. I tried right clicking on the project and clicking on Android Tools - Fix Project Properties. But nothing changed. Any pointers on what I am doing wrong much be appreciated.

  • Fixing CSS positioning and scaling

    - by Louis
    I was contemplating writing a UI toolkit where setting the position and size of an element/widget was intuitive and powerful. Here are some examples of how it would be used (not currently implemented): ui("Panel").size(". 40").pos("0 0").attach(element); ui("Textarea").size(". %-10").pos("0 40").attach(element); ui("Panel").size(". 10").pos("0 bottom+5"); Where . means auto, % means 100% and the possibility to add pixels to percentages. Does anything like said exist (even as a jQuery plugin or something)? Somethings just aren't possible with pure CSS.

  • What is the best way to keep database data encrypted with user passwords?

    - by Dan Sosedoff
    Let's say an application has really specific data which belongs to a user, and nobody is supposed to see it except the owner. I use MySQL database with DataMapper ORM mapper. The application is written in Ruby on Sinatra. Application behavior: User signs up for an account. Creates username and password. Logs into his dashboard. Some fields in specific tables must be protected. Basically, I'm looking for auto-encryption for a model properties. Something like this: class Transaction include DataMapper::Resource property :id, Serial property :value, String, :length => 1024, :encrypted => true ... etc ... belongs_to :user end I assume that encryption/decryption on the fly will cause performance problems, but that's ok. At least if that works - I'm fine. Any ideas how to do this?

  • How to calculate textarea cols with 100% width?

    - by sehwoo
    I set the width of a textarea to 100%, but now I need to know how many characters can fit in one row. I'm trying to write a javascript function to auto-grow/shrink a textarea. I'm trying to keep from using jquery since I just need this one function. My logic is to rows = textarea.value.split('\n'), iterate through rows and count += rows[i].length/textarea.cols, then count += rows.length, and finally textarea.rows = count. The only problem is that count is too large because textarea.cols is too small.

  • jquery easy image slider

    - by Jack
    Using easy slider to scroll through Images . It's working occasionally (on a refresh), but more often not. The height of the slide and also the position get screwed up on load for seconds. This style was applied to the style="width: 1308px; height: 70px; overflow-x: hidden; overflow-y: hidden;" I'm not sure where it's pulling those values from (height and width) the slide not expanding vertically to reveal the content and the slide being out of position horizontally. I have this style applied to #slider width:538px; height:auto; overflow:hidden; but they're not being passed correctly.

  • C++0x optimizing compiler quality

    - by aaa
    hello. I do some heavy numbercrunching and for me floating-point performance is very important. I like performance of Intel compiler very much and quite content with quality of assembly it produces. I am thinking at some point to try C++0x mainly for sugar parts, like auto, initializer list, etc, but also lambdas. at this point I use those features in regular C++ by the means of boost. How good of assembly code do compilers C++0x generate? specifically Intel and gcc compilers. Do they produce SSE code? is performance comparable to C++? are there any benchmarks? My Google search did not reveal much. Thank you.

  • NotificationCenter Widget Failed To Use CoreLocation

    - by James Ye
    I'm writing a notification center widget, and it had to use location information. In normal apps I use CoreLocation and it works fine. But in my widget, I tried to locationServicesEnabled but it didn't go to the callback functions, and the authorizationStatus is always kCLAuthorizationStatusNotDetermined, and the authorize setting didn't show up in Setting - location service. I already set the delegate to the class. The system's Yahoo weather widget can auto locating and it uses CoreLocation too, so the widget do have ability to use location service. Why CoreLocation doesn't work on my widget?

  • Sending data between forms without using .Show()

    - by slodice
    Lets say I have 2 forms. In Form1 I have a timer, which counts (count++) and in Form2 I have a text box (textBox1) which shows how much the timer has counted. Now I want to know how would I show the integer 'count' in 'textBox1' without any user interference (clicking buttons) or in other words, how would I make the data in the text box auto refresh (without using Form2 form = new Form2(); form.Show();). I want 2 separate windows, in one a running timer and in the other a textbox displaying how much the timer has counted and constantly updating (with the help of the timer, I presume).
