  • Prevent Windows Explorer from interfering with Directory operations.

    - by Bruno Martinez
    Sometimes, no "foo" directory is left after running this code: string folder = Path.Combine(Path.GetTempPath(), "foo"); if (!Directory.Exists(folder)) Directory.CreateDirectory(folder); Process.Start(@"c:\windows\explorer.exe", folder); Thread.Sleep(TimeSpan.FromSeconds(5)); Directory.Delete(folder, false); Directory.CreateDirectory(folder); It seems Windows Explorer keeps a reference to the folder, so the last CreateDirectory has nothing to do, but then the original folder is deleted. How can I fix the code?

  • Dinamically creating a member ID card as pdf using PHP?

    - by aefxx
    I need to code a PHP script that would let me generate a pdf file which displays a member ID card (something like a credit card used to identify oneself) at a certain resolution. Let me explain: I do have the basic blueprint of the card in png file format. The script needs to drop in a member's name and birth day along with a serial. So far, no problem - there are plenty of good working PHP librarys out there. My problem is to ensure that the resulting pdf (the generated image of the card, to be precise) meets a certain resolution (preferably 300dpi), so that printing it would look right. Any ideas? EDIT I solved it using the TCPDF library which let's you scale images at a certain resolution. Get it here: http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=tcpdf

  • Execute C++ exe from C# form using Process.start()

    - by Dan
    Hi, I'm trying to create a C# form app that will allow me to use all of my previous C++ programs from one central program. I'm able to open the exes with Process.start, however it does not compile the code correctly. Example code: Process.Start("C:\\Documents and Settings\\dan\\Desktop\\test.exe"); This will bring up the console and act like it's running, but it does not run like when I normally compile out of the C++ editor. Is there a startinfo variable I need to set to signify that it's a c++ program or something along that line? Also, is there any way to execute a C++ program using process.start that will allow me to pass it variables through the command line via argc and argv? Thanks

  • Lock-free multi-threading is for real threading experts...

    - by vdhant
    I was reading through an answer that Jon Skeet gave to a question and in it he mentioned this: As far as I'm concerned, lock-free multi-threading is for real threading experts, of which I'm not one. Its not the first time that I have heard this, but I find very few people talking about how you actually do it if you are interested in learning how to write lock-free multi-threading code. So my question is besides learning all you can about threading, etc where do you start trying to learn to specifically write lock-free multi-threading code and what are some good resources. Cheers

  • Ideas on collaborating with small number of people

    - by Mark Szymanski
    Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!

  • Programmatic use of ARP

    - by sizzzzlerz
    I have a need for some C or C++ code, compilable under Linux, to be able to take a list of IP addresses of some arbitrary number of remote hosts machines and obtain a ethernet MAC address for each one. These host machines may be on the same subnet or they could be on a different subnet behind a router. Its OK if the MAC address of some or all of the remote hosts is the address of the interface on the router. Ultimately, I want to hand off the IP address and MAC address to an FPGA who will use these pieces of information to format and send UDP/IP packets over ethernet to the hosts. Obviously, the FPGA will also be given its own MAC address and IP address to fill in the source MAC and source IP addresses in the packets. Is there some code I can be pointed to that can create and broadcast ARP packets to these remote machines and receive back the ARP response packets such that the destination MAC addresses can be extracted?

  • How do I get the java.concurrency.CyclicBarrier to work as expected

    - by Ritesh M Nayak
    I am writing code that will spawn two thread and then wait for them to sync up using the CyclicBarrier class. Problem is that the cyclic barrier isn't working as expected and the main thread doesnt wait for the individual threads to finish. Here's how my code looks: class mythread extends Thread{ CyclicBarrier barrier; public mythread(CyclicBarrier barrier) { this.barrier = barrier; } public void run(){ barrier.await(); } } class MainClass{ public void spawnAndWait(){ CyclicBarrier barrier = new CyclicBarrier(2); mythread thread1 = new mythread(barrier).start(); mythread thread2 = new mythread(barrier).start(); System.out.println("Should wait till both threads finish executing before printing this"); } } Any idea what I am doing wrong? Or is there a better way to write these barrier synchronization methods? Please help.

  • ShowWindow not working from a DLL on a 64-bit OS?

    - by Auto Roast
    I have a process that calls SetWindowsHook to catch keyboard events. In the DLL that processes the events, I conditionally call ShowWindow on the handle of the window of the process who set the hook. That code works perfectly on a 32-bit OS (XP) and as a 32-bit application on a 64-bit OS, but when compiled to 64-bit, the window is not showing. The code to make the window visible is: if (idx == passlen) { HWND h = FindWindow(NULL,windowNameToShow); ShowWindow(h,SW_SHOW); idx = 0; logger->backerase(passlen - 1); nextCharToMatch = passPointer; }

  • Is it an MD5 digest in this Python script?

    - by brilliant
    Hello, I am trying to understand this simple hashlib code in Python that has been given to me the other day on "Stackoverflow": import hashlib m = hashlib.md5() m.update("Nobody inspects") m.update(" the spammish repetition here") m.digest() '\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' m.digest_size 16 m.block_size 64 print m I thought that "print m" would show me the MD5 digest of the phrase: "Nobody inspects the spammish repetition here", but as a result I got this line on my local host: <md5 HASH object @ 01806220> Strange, when I refreshed the page, I got another line: <md5 HASH object @ 018062E0> and every time when I refresh it, I get another value: md5 HASH object @ 017F8AE0 md5 HASH object @ 01806220 md5 HASH object @ 01806360 md5 HASH object @ 01806400 md5 HASH object @ 01806220 Why is it so? I guess, what I have in each line flowing "@" is not really a digest. Then, what is it? And how can I display MD5 digest here in this code? My python version is Python 2.5 and the framework I am currently using is webapp (I have downloaded it together with SDK from "Google App Engine")

  • NSLog crashing app using 3.1.3 software

    - by Matt Facer
    Hi guys - the other day I had a bug submitted for my app from a user on an ipod touch with 3.1.3 software. It was a strange bug as no-one else has submitted it yet. Long story short, it appears that anywhere where I have NSLog() in code it will actually crash the app. I tried stripping out ALL the code other than NSLog(@"hello") and running on my iphone (3.1.3) it indeed did crash. I removed the NSLog and it worked. Has anyone else had this problem?? PS) I am now aware that we shouldn't release an app with NSLog still in use... so they've all gone now!

  • Jruby embedded modules and classes.

    - by James Moore
    Hey, I have a ruby file as follows: module Example class Myclass def t_st "Hello World!" end end end now if this was just a class I would be able to use the following java code: ScriptEngine jruby = new ScriptEngineManager().getEngineByName("jruby"); jruby.eval(new BufferedReader(new FileReader("example.rb"))); Object example = jruby.eval("myclass.new"); However, this class rests inside a module. Calling the same code as above produces the error: Exception in thread "main" org.jruby.embed.EvalFailedException: uninitialized constant myclass In addition, calling: Object example = jruby.eval("Example"); The module returns no error. So one would assume this follows the format for Ruby. Object example = jruby.eval("Example::myclass.new"); Again however, I get the same error as before. Can anyone help? As there is little documentation on JRuby? Thanks

  • Java input method for Virtual Keyboad

    - by shekhar
    Hi, I am facing problem in implementing Input method for Virtual Keyboard, currently I am using robot class for sending input to any application from virtual keyboard. but for that I need to create mapping of key-code and unicode, which is not consistent on different keyboard layout, can I directly pass the UNICODE to any application using Input method without worry about mapping between keycode and unicode. any useful link or sample code will be useful. It is simple Java program which is always on top of any application and work as onscreen keyboard. using a mouse while you press any button (key) of the keyboard, the corresponding character will be typed in the application running below. This is working perfectly for English Alphabets. I am facing problem while I am doing for unicode.

  • Custom whiteSpace using Haskell Parsec

    - by fryguybob
    I would like to use Parsec's makeTokenParser to build my parser, but I want to use my own definition of whiteSpace. Doing the following replaces whiteSpace with my definition, but all the lexeme parsers still use the old definition (e.g. P.identifier lexer will use the old whiteSpace). ... lexer :: P.TokenParser () lexer = l { P.whiteSpace = myWhiteSpace } where l = P.makeTokenParser myLanguageDef ... Looking at the code for makeTokenParser I think I understand why it works this way. I want to know if there are any workarounds to avoid completely duplicating the code for makeTokenParser?

  • Mouse wheel not scrolling in JDialog

    - by Iulian Serbanoiu
    Hello, I'm facing a frustrating issue. I have an application where the scroll wheel doesn't work in a JDialog class. Here's the code: import javax.swing.*; import java.awt.event.*; public class Failtest extends JFrame { public static void main(String[] args) { new Failtest(); } public Failtest() { super(); setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); setTitle("FRAME"); JScrollPane sp1 = new JScrollPane(getNewList()); add(sp1); setSize(150, 150); setVisible(true); JDialog d = new JDialog(this, false);// NOT WORKING //JDialog d = new JDialog((JFrame)null, false); // NOT WORKING //JDialog d = new JDialog((JDialog)null, false);// WORKING - WHY? d.setTitle("DIALOG"); d.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); JScrollPane sp = new JScrollPane(getNewList()); d.add(sp); d.setSize(150, 150); d.setVisible(true); } public JList getNewList() { String objs[] = new String[30]; for(int i=0; i<objs.length; i++) { objs[i] = "Item "+i; } JList l = new JList(objs); return l; } } I found a solution which is present as a comment in the java code - the constructor receiving a (JDialog)null parameter. Can someone enlighten me? My opinion is that this is a java bug.

  • Drupal clean urls on custom page GET request.

    - by calebthorne
    I have a drupal page (content type page) that should accept GET values using clean urls. I put the following code in the page body using the php code input format. <?php $uid = $_GET['uid']; $user = user_load($uid); print $user->name; ?> Now the following link http://www.example.com/mypath/?uid=5 results in user 5's name being displayed. Great. My question is: Can this be accomplished using clean urls such that going to http://www.example.com/mypath/5 has the same result? (Similar to using arguments in views)

  • Javascript draw dynamic line

    - by Ranch
    Hello, I'm looking for Javascript code for letting the user draw a line (on an image). Just as the line tool in Photoshop (for example): The user clicks on the image, drags the mouse (while the line between the start point and the mouse point is dynamically drawn on mouse drag). I would also need a callable function to send the page the start and end coordinates. I've found this very nice script for area selection: http://www.defusion.org.uk/code/javascript-image-cropper-ui-using-prototype-scriptaculous/ and I've found many script for drawing lines (and other shapes in JS), but could not find what I'm looking for. Thanks

  • Best practices for developing simple ASP.NET sites (built in controls or JQuery + scripts)

    - by Nix
    I was recently reviewing some code written by two different contractors, both were basic ASP.NET management sites. The sites allowed the user to view and edit data. Pretty much simple CRUD gateways. One group did their best to use built in ASP + AJAX Toolkit controls and did their best to use as many built in controls as possible. I found the code much easier to read and maintain. The other used jQuery and the code is heavily marked up with script blocks which are then used to build pages from javascript files. Which one is more common? The one that basically leveraged embedded HTML markup in scripts controled by javascript files screams readability and maintenance issues? Is this just the way of doing asp dev with jQuery? Assuming the second example happens a lot, are there tools that help facilitate jQuery development with visual studio? Do you think they generated the html somewhere else and just copied it in? Example Script block: <script id="HRPanel" type="text/html"> <table cellpadding='0' cellspacing='0' class="atable"><thead class="mHeader"><tr><th>Name</th><th>Description</th><th>Other</th></thead><tbody> <# for(var i=0; i < hrRows.length; i++) { var r = HRRows[i]; #> <tr><td><#=r.Name#></td><td><#=r.Description#></td><td class="taRight"><#=r.Other#></td></tr> <#}#> </tbody><tfoot><th></th><th></th><th></th></tfoot></table> </script> Then in a separate location (js file) you would see something like this. $("#HRPanel").html($("#HRPanel").parseTemplate({ HRRows: response.something.bah.bah }));

  • Implementing IPermission

    - by joniba
    Hi there, I'm considering writing a custom IPermission implementation but am not clear as to how it should work. I've already implemented IPrincipal and IIdentity. What I would like to accomplish is to be able to check permissions vis a vis the current IPrincipal's authorizations rather than its roles. Generally, authorizations are read/add-delete/update/none for a given type. So I would like to write something like this: [CustomPermission(SecurityAction.Demand, Type = typeof(Foo), MinimumAuthorization = AuthorizationFlags.Read)] public void SomeMethod(){} Is this possible? I've looked over the code at http://msdn.microsoft.com/en-us/library/system.security.ipermission.aspx. This shows how to implement the interface, but I don't understand how the above pseudo-code would be able to check against the IPrincipal's authorizations for the type. Any help or resource references would be appreciated. Joni

  • Complex error handling

    - by Caspin
    I've got a particularly ornery piece of network code. I'm using asio but that really doesn't matter for this question. I assume there is no way to unbind a socket other than closing it. The problem is that open(), bind(), and listen() can all throw a system_error. So I handled the code with a simple try/catch. The code as written in broken. using namespace boost::asio; class Thing { public: ip::tcp::endpoint m_address; ip::tcp::acceptor m_acceptor; /// connect should handle all of its exceptions internally. bool connect() { try { m_acceptor.open( m_address.protocol() ); m_acceptor.set_option( tcp::acceptor::reuse_address(true) ); m_acceptor.bind( m_address ); m_acceptor.listen(); m_acceptor.async_accept( /*stuff*/ ); } catch( const boost::system::system_error& error ) { assert(acceptor.is_open()); m_acceptor.close(); return false; } return true; } /// don't call disconnect unless connect previously succeeded. void disconnect() { // other stuff needed to disconnect is ommited m_acceptor.close(); } }; The error is if the socket fails to connect it will try to close it in the catch block and throw another system_error about closing an acceptor that has never been opened. One solution is to add an if( acceptor.is_open() ) in the catch block but that tastes wrong. Kinda like mixing C-style error checking with c++ exceptions. If I where to go that route, I may as well use the non-throwing version of open(). boost::system::error_code error; acceptor.open( address.protocol, error ); if( ! error ) { try { acceptor.set_option( tcp::acceptor::reuse_address(true) ); acceptor.bind( address ); acceptor.listen(); acceptor.async_accept( /*stuff*/ ); } catch( const boost::system::system_error& error ) { assert(acceptor.is_open()); acceptor.close(); return false; } } return !error; Is there an elegant way to handle these possible exceptions using RAII and try/catch blocks? Am I just wrong headed in trying to avoid if( error condition ) style error handling when using exceptions?

  • How Gridview co-operates with ObjectDataSource?

    - by sanjuro
    Hi, how Gridview co-operates with ObjectDataSource internally? When you set DataSourceID of GridView, assigned ObjectDataSource take care of such things as paging and sorting, but i don't have full control above databinding itself, on the other side when i set datasource of gridview in code-behind: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { testGridView.DataSource = testObjectDataSource.Select(); testGridView.DataBind(); } } Now i have full control, but i have lost the advantage of comfort sorting and paging. And that co-operation between ObjectDataSource and Gridview became mystery for me. So can anybody explain me in details how ObjectDataSource and Gridview co-operates under the hood? I want to understand it in order to write my own smart code or own gridview that will mimic this co-operation. Many thanks for answers.

  • How do I give each test its own TestResults folder?

    - by izb
    I have a set of unit tests, each with a bunch of methods, each of which produces output in the TestResults folder. At the moment, all the test files are jumbled up in this folder, but I'd like to bring some order to the chaos. Ideally, I'd like to have a folder for each test method. I know I can go round adding code to each test to make it produce output in a subfolder instead, but I was wondering if there was a way to control the output folder location with the Visual Studio unit test framework, perhaps using an initialization method on each test class so that any new tests added automatically get their own output folder without needing copy/pasted boilerplate code?

  • OpenID on Google not returning anything

    Hi there, For some reason, the following code does not return anything: string alias = response.FriendlyIdentifierForDisplay; var sreg = response.GetExtension<ClaimsResponse>(); if (sreg != null && sreg.MailAddress != null) { alias = sreg.MailAddress.User; } if (sreg != null && !string.IsNullOrEmpty(sreg.Email)) { alias = sreg.Email; } if (sreg != null && !string.IsNullOrEmpty(sreg.FullName)) { alias = sreg.FullName; } I was hoping I can get the Email from Yahoo or Google, but sreg just return null whichever provider I have chosen. I saw some of other posts that this code should return an e-mail at least, but for me, it does not, please assist. Thanks alot
