  - by bks

  Hello i have a cpp code wich i'm having trouble reading. a class B is defined now, i understand the first two lines, but the rest isn't clear enough. is the line "B const * pa2 = pa1" defines a const variable of type class B? if so, what does the next line do?

• Is it possible to integrate NUnit with VB.net Express Edition? Which is the best way?

  - by Kico Lobo

  Hi, I'm a Java Developer wich is learning VB.net for a small project. While coding in Java, we don't have to think a lot about how to integrate our IDE with our unit test framework because most of the IDEs already area integrated. But now that I'm working on a project which the main requirement is to use VB.net Express Edition, is it possible to integrate this IDE with NUnit? How can I do that? Is there a better practice for this task? What should I do? No, we can't opt to use Visual Studio, only the Express Edition of VB.net

• Do people create and use Web Parts connections?

  - by Javaman59

  I've been writing some SharePoint web parts wich connect (as providers and consumers). I've found many difficulties, and (comparatively*) little material from the web, from books, or from microsoft.com, which is quite surprising as Web Parts have been around since 2003. This is making me think that although web part connections look like a first class feature in SharePoint, that in practice few people write connecting web parts, and few SharePoint users use them. Is this the case - that few developers write connecting web parts, and few users use them? *comparitively: A subjective impression. With each specific problem i usually find only a handful of web pages which address it, and as my problems seem to be fundamental ones (such which data type to wrap in an IWebPartRow), I expect a lot more search results.

• getcwd for current location based on ftp account permission

  - by John Doe

  Hello. I'm trying to make a small script that's changing the permission for specific file using a ftp connection. My problem is the absolute path. I have a ftp account wich land on the script directory (/script/). If i'm using getcwd, it will return the whole path (/home/user/public_html/script) but i need only the difference between the full path and the current path (getcwd path: /home/user/public_html/script/ ftp landing path: /script). So, how can i use getcwd to get the current directory for a ftp account? For example, if the user is landing in public_html, the path to the script will be /script/, or if he is landing inside /user, the path will be /public_html/script. Thanks

• modx revo snippet variable in query

  - by Meddie

  I noticed something weird when using a query in a snippet. When I have a query like this: $sql = 'SELECT * FROM table WHERE colomn = ' . $variable; And I echo $sql, the query reads: SELECT * FROM table WHERE colomn = <code class="php plain">2</code> .. wich will result in an error because the sql is no longer valid. So for now I use strip_tags to remove the code tag, but I find it not a very clean method. I couldnt find anything about this, so maybe someone can shed some light on this for me?

• (Re)Enabling JavaScript debugger in IE7 with Visual Studio 2008

  - by masterik

  Visual Studio 2008 comes with nice javascript debugging features. But I have played a little with NetBeans debugger wich has installed an ugly Script Debugger from Microsoft to my IE... Normally IE should ask what do I want to use for debugging, but now I can't start debugging with Visual Studio, the Script Debugger is started automatically... After uninstalling the Script Debugger I can't debug in IE at all. Even attaching to iexplore.exe process doesn't helps... Has installed the Script Debugger again... :((((( How can I get back my Visual Studio debugging working in IE again?

• jquery fancy box

  - by André Alçada Padez

  Hi, i'm using fancy box for some content editing in my backoffice. I recently added an image manager wich i create with javascript. It's kind of like a fancybox, but i had to do it from scractch for it to be able to overlay the first one. My problem is this: I want to have the user being able to press the escape key to close my manager, but if i use $(window).keypress when i press the esc key, both the boxes close. I have tried $(window).unbind('keypress') when i start loading my box, and i have tried to look through the fancybox js file, but it is minimized. Does anyone know how i can disable and afterwards enable the escape key (during runtime) on the fancybox? Thanx

• How to use Zend_Cache Identifier ?

  - by ArneRie

  Hi Folks, i think iam getting crazy, iam trying to implement Zend_Cache to cache my database query. I know how it works and how to configure. But i cant find a good way to set the Identifier for the cache entrys. I have an method wich search for records in my database (based on an array with search values). /** * Find Record(s) * Returns one record, or array with objects * * @param array $search Search columns => value * @param integer $limit Limit results * @return array One record , or array with objects */ public function find(array $search, $limit = null) { $identifier = 'NoIdea'; if (!($data = $this->_cache->load($identifier))) { // fetch // save to cache with $identifier.. } But what kind of identifier can use in this situation?

• Displaying a collection of controls in a specific way in WPF

  - by Alvaro

  I have a collection of controls "MyCollection" wich changes in the Runtime. And I have to follow some constraints for that, for example: If my parameter "MyCollection.Count = 4" the property "NumberOfcolumns" will have the value 2, in order to create new Lines, and show the controls Two per Two. This is how I'm displaying my collection : <ItemsControl ItemsSource="{Binding MyCollection}" BorderThickness="0" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate > <UniformGrid Columns="{Binding NumberOfColumns}" VerticalAlignment="Center" HorizontalAlignment="Center" Background="Transparent"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> The problem is that my controls have different sizes, and as In UniformGrids, Cells are uniform... My design is not really pretty, because I have little controls shown in big Cells !! Can someone help me to solve this problem ? NB: Please give me a detailled solution if possible, not something like : "Use WrapPanel..."

• Mean of Sampleset and powered Sampleset

  - by Milla Well

  I am working on an ICA implementation wich is based on the assumption, that all source signals are independent. So I checked on the basic concepts of Dependence vs. Correlation and tried to show this example on sample data from numpy import * from numpy.random import * k = 1000 s = 10000 mn = 0 mnPow = 0 for i in arange(1,k): a = randn(s) a = a-mean(a) mn = mn + mean(a) mnPow = mnPow + mean(a**3) print "Mean X: ", mn/k print "Mean X^3: ", mnPow/k But I couldn't produce the last step of this example E(X^3) = 0: >> Mean X: -1.11174580826e-18 >> Mean X^3: -0.00125229267144 First value I would consider to be zero, but second value is too large, isn't it? Since I subtract the mean of a, I expected the mean of a^3 to be zero as well. Does the problem lie in the random number generator, the precision of the numerical values in my misunderstanding of the concepts of mean and expected value?

• User Interface Diagram That is always reachable

  - by Fosa

  If you have to build a flow of a Use-case by drawing each Interface Diagram. Then you would start with a Diagram like say "login". But after the login page, no mather wich page you choose except the "logout" page, you always have your navigation bar right ? So all the options in the navigation bar? Like account page , personal page, etc... Do you have to make sure in your flow that in every diagram there is acces to the "accountpage" diagram ? Or do they have an other solution for that ?

• Sending passwords over the web

  - by Falmarri

  So I'm working on a mobile platform application that I'd like to have users authenticate over the web. I was wondering the best way to do security. The user is sending a password for HTTP to a php server wich authenticates against a mysql database on the same server. Obviously I don't want to send the password in plain text over the internet, but I also don't want to do 2 SHA hashes. This is what the server looks like (in pseudocode) $pass = $_POST['pass']; if ((get PASSWORD where USERNAME = USERNAME) == SHA($pass)) return PASS; This is pretty standard and I don't think there's any other way to do this. But I was wondering how I should prepare the data before sending it over the internet.

• Google maps z-index problem in IE

  - by Bas van de Lustgraaf

  I'm loading my google maps into div class="extra" style="display: none;" /. As soon as the AJAX request is complete, the map_canvas div is placed inside the hidden div and the hidden div will be vissible with the toggleDown jquery effect. In FF it's working perfect, but in IE the Google maps (map_canvas div) is already visible before the toggleDown effect is started. I think the z-index and the relative position of the map_canvas div wich is loaded into the hidden div will place the map_canvas div on top of the hidden div. What do i have to change to make sure the map_canvas div is not on top of the hidden div? While toggleDown in FF: http:// img169.imageshack.us/img169/9274/50485429.jpg While toggleDown in IE: http://img188.imageshack.us/img188/2110/93959677.jpg

• Fastest way to find the rotation of a vector

  - by kriss

  I have two 2D vectors, say u and v, defined by cartesian coordinates. Imagine that vectors are needles of a clock. I'm looking for the fastest way to find out, using python, if v is after or before u (or in other words find out in wich half plane is v, regarding to position of u). For the purpose of the problem if vectors are aligned answer should be before. It seems easy using some trigonometry, but I believe there should be a faster way using coordinates only. My test case: def after(u, v): """code here""" after((4,2), (6, 1)) : True after((4,2), (3, 3)) : False after((4,2), (2, 1)) : False after((4,2), (3, -3)) : True after((4,2), (-2, -5)) : True after((4,2), (-4, -2)) : False

• C++ serial port send command

  - by Ilyssis

  Hi there, I have a hardware here, wich communicates over serial port. I use MS Visual C++ 2010, and I want to send a command: <-S-> I am doing this: SerialPort^ serialPort = gcnew SerialPort(portName , 9600, Parity::None, 8, StopBits::One); serialPort->Open(); serialPort->WriteLine("<-S->"); serialPort->Close(); But the command that goes out is <-S->., and not <-S-> (please notice the point that is attached to the outgoing command). I use Free Serial Port Monitor to watch my ingoing/outcoming data. So how can I get rid of that point in <-S->. ? This is what is going out: 3C 2D 53 2D 3E 0A = <-S-. This is what I want: 3C 2D 53 2D 3E = <-S- Thanks for help.

• Getting unique items from NSMutableArray

  - by Gidogeek

  Hi Guys, I have a question about Objective-C today involving NSMutableArray. Coming from a .net/c# background I'm having some trouble working with these things. Let's say I have an object called "Song" My song has 3 properties: Title Artist Genre I have a NSMutableArray or NSArray wich holds all my Song objects. How would I go about trying to 'query' my array to get a new array with only (Unique) Artists or Genre's. Where as in .net you would write a simple LINQ query with a DISTINCT clause, how would one solve this in Objective-C ? I'm guessing with predicates but am struggling to find a solution. Thanks in advance.
