  • Passing multiple codeblocks as arguments

    - by doctororange
    I have a method which takes a code block. def opportunity @opportunities += 1 if yield @performances +=1 end end and I call it like this: opportunity { @some_array.empty? } But how do I pass it more than one code block so that I could use yield twice, something like this: def opportunity if yield_1 @opportunities += 1 end if yield_2 @performances +=1 end end and: opportunity {@some_other_array.empty?} { @some_array.empty? } I am aware that this example could be done without yield, but it's just to illustrate. Thanks.

  • How to reuse socket in .NET?

    - by Hermann
    I am trying to reconnect to a socket that I have disconnected from but it won't allow it for some reason even though I called the Disconnect method with the argument "reuseSocket" set to true. _socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); _socket.Connect(ipAddress, port); //...receive data _socket.Disconnect(true); //reuseSocket = true //...wait _socket.Connect(ipAddress, port); //throws an InvalidOperationException: Once the socket has been disconnected, you can only reconnect again asynchronously, and only to a different EndPoint. BeginConnect must be called on a thread that won't exit until the operation has been completed. What am I doing wrong?

  • How to list all attached USB devices in Visual C++

    - by vinzenzweber
    In Short: I need to detect hotplug events of my USB CDC device by PID/VID and get the corresponding virtual COM port which was created by Windows in Visual C++ and in the end create a dll. I have a USB CDC device which I need to be notified of when connected/disconnected on Windows. My approach is to use RegisterDeviceNotification and an "invisible" Window to receive WM_DEVICECHANGE notifications. This part is working so far. Now as far as I found out I need to get the list of USB devices that is plugged, iterate over it and filter out the devices with my PID/VID? I assume that I am then able to get more informations about the device including the COM port? Is the only way to achieve my goal to use SetupDi calls in setupapi.h? Is using WDK / DDK the only way to achieve my goal? As soon as that is working I open-source it on http://github.com/vinzenzweber/USBEventHandler. The Mac version is available already!

  • interesting network or git problem

    - by bogumbiker
    I have a setup my own git repository with gitosis on dedicated debian server. The server is visible via port 22 from outside (the port 22 is forwarded from my router to my git server). On the local network the git repository works perfectly. The problem happens once I try to do "git clone.." from remote server. So once I do "git clone.." from remote I am getting git clone hung after cloning around 20-30% of the repository (small around 2MB) and I think this is the random percentage. I can do scp to and from the git server without any problems. Also as I mentioned the git clone, push, etc works perfectly within my internal network. Any idea how to debug this problem? thanks

  • NSInteger differences between CLI and GUI ?

    - by d11wtq
    I've been building a framework and writing unit tests in GHUnit. One of my Framework's accessor methods returns an NSInteger. I assert the expected value in the tests like this: GHAssertEquals(1320, request.port, @"Port number should be 1320"); When running my tests with an AppKit UI based frontend this assertion passes. However, when I run my tests on the command line, it fails with a type-mismatch unless I type-cast my hard-coded 1320 as (NSInteger). What's causing the difference in the way the integer is being interpreted by the compiler? Is xcodebuild on the command line using a different data-type for hard coded integers?

  • Catch isn't working

    - by neoneye
    I'm baffled. What could be causing 'catch' not to be working and how do I fix it? <?php try { throw new Exception('BOOM'); error_log("should not happen"); } catch(Exception $e) { error_log("should happen: " . $e->getMessage()); } ?> Actual output [27-Apr-2010 09:43:24] PHP Fatal error: Uncaught exception 'Exception' with message 'BOOM' in /mycode/exception_problem/index.php:4 Stack trace: #0 {main} thrown in /mycode/exception_problem/index.php on line 4 Desired output should happen: BOOM PHP version 5.2.3 In php_info() I don't see anywhere exceptions could have been disabled. I have tried with "restore_exception_handler();" but that doesn't make the catch block working. I have also tried with "set_exception_handler(NULL);" but that neither make the catch block working. How do I get the desired output?

  • Drupal: Create custom search

    - by Dr. Hfuhruhurr
    I'm trying to create a custom search but getting stuck. What I want is to have a dropdownbox so the user can choose where to search in. These options can mean 1 or more content types. So if he chooses options A, then the search will look in node-type P,Q,R. But he may not give those results, but only the uid's which will be then themed to gather specific data for that user. To make it a little bit clearer, Suppose I want to llok for people. The what I'm searching in is 2 content profile types. But ofcourse you dont want to display those as a result, but a nice picture of the user and some data. I started with creating a form with a textfield and the dropdown box. Then, in the submit handler, i created the keys and redirected to another pages with those keys as a tail. This page has been defined in the menu hook, just like how search does it. After that I want to call hook_view to do the actual search by calling node_search, and give back the results. Unfortunately, it goes wrong. When i click the Search button, it gives me a 404. But am I on the right track? Is this the way to create a custom search? Thx for your help. Here's the code for some clarity: <?php // $Id$ /* * @file * Searches on Project, Person, Portfolio or Group. */ /** * returns an array of menu items * @return array of menu items */ function vm_search_menu() { $subjects = _vm_search_get_subjects(); foreach ($subjects as $name => $description) { $items['zoek/'. $name .'/%menu_tail'] = array( 'page callback' => 'vm_search_view', 'page arguments' => array($name), 'type' => MENU_LOCAL_TASK, ); } return $items; } /** * create a block to put the form into. * @param $op * @param $delta * @param $edit * @return mixed */ function vm_search_block($op = 'list', $delta = 0, $edit = array()) { switch ($op) { case 'list': $blocks[0]['info'] = t('Algemene zoek'); return $blocks; case 'view': if (0 == $delta) { $block['subject'] = t(''); $block['content'] = drupal_get_form('vm_search_general_form'); } return $block; } } /** * Define the form. */ function vm_search_general_form() { $subjects = _vm_search_get_subjects(); foreach ($subjects as $key => $subject) { $options[$key] = $subject['desc']; } $form['subjects'] = array( '#type' => 'select', '#options' => $options, '#required' => TRUE, ); $form['keys'] = array( '#type' => 'textfield', '#required' => TRUE, ); $form['submit'] = array( '#type' => 'submit', '#value' => t('Zoek'), ); return $form; } function vm_search_general_form_submit($form, &$form_state) { $subjects = _vm_search_get_subjects(); $keys = $form_state['values']['keys']; //the search keys //the content types to search in $keys .= ' type:' . implode(',', $subjects[$form_state['values']['subjects']]['types']); //redirect to the page, where vm_search_view will handle the actual search $form_state['redirect'] = 'zoek/'. $form_state['values']['subjects'] .'/'. $keys; } /** * Menu callback; presents the search results. */ function vm_search_view($type = 'node') { // Search form submits with POST but redirects to GET.

  • Domain Keys, DKIM and Sendmail

  • Android - making a layout like Entourage/Outlook calendar

    - by teepusink
    Hi, I'm trying to build a layout / view like the Entourage/Outlook calendar view, where when I schedule a time block, a new view will popup overlaying the time block. Something like this one except it's daily and not monthly like in the image http://images.appleinsider.com/office-2008-entourage-10.png What is the best way to implement that? Right now I'm using TableLayout to create the time on the 1st column and supposedly overlay to schedule made on the 2nd column. However, things got very messy especially when the minutes go to 15 minutes and there are overlapping schdule. Wonder if using other layout might work better? Thanks, Tee

  • Removing http301 redirect from client's cache

    - by ChessWhiz
    Hi, I have a server/client architecture where the client hits the ASP.NET server's service at a certain host name, IP address, and port. Without thinking, I logged on to the server and set up permanent HTTP301 redirection through IIS from that service to another URL that the machine handles via IIS (same IP and port), mistakenly thinking it was another site that is hosted there. When the client hit the server at the old host name, it cached the permanent redirect. Now, even though I have removed the redirection, the client no longer uses the old address. How can I clear the client's cache so that it no longer stores the redirect? I have read about how permanent HTTP301 can be, but in this case, it should be possible to reset a single client's knowledge of the incorrectly-learned host name. Any ideas?

  • How to recover gracefully from a C# udp socket exception

    - by Gearoid Murphy
    Context: I'm porting a linux perl app to C#, the server listens on a udp port and maintains multiple concurrent dialogs with remote clients via a single udp socket. During testing, I send out high volumes of packets to the udp server, randomly restarting the clients to observe the server registering the new connections. The problem is this: when I kill a udp client, there may still be data on the server destined for that client. When the server tries to send this data, it gets an icmp "no service available" message back and consequently an exception occurs on the socket. I cannot reuse this socket, when I try to associate a C# async handler with the socket, it complains about the exception, so I have to close and reopen the udp socket on the server port. Is this the only way around this problem?, surely there's some way of "fixing" the udp socket, as technically, UDP sockets shouldn't be aware of the status of a remote socket? Any help or pointers would be much appreciated. Thanks.

  • ASP.Net State Server on EC2 not connection

    - by CountCet
    I am trying to set up an Asp.Net State Server on Amazon EC2. The single web server using this State Server is also on EC2. I've done the following things. I've added the IIS role on the State Server. I changed the value in the registry to allow connections for the service and started the aspstate service. I verified it is listening on port 42424 by checking netstat. I edited the web.config of the Web server to point to this server. I added the the tcp port to my EC2 security group and allowed it for all incoming ip's. Anything else I am not doing?

  • Delphi OLE - How to avoid errors like "The requested member of the collection does not exist"?

    - by Edwin
    Hi, I'm automating Word with Delphi, but some times I got an error message: The requested member of the collection does not exist It seems that the Item member of the Styles collection class does not always exist and some times causes the above mentioned error. My workaround is to catch the exception and skip it, but is there anyway to detect it instead of using the try...except block? The problem with the try...except block is that when debugging the raised exception is annoying... My code example: var aWordDoc: _WordDocument i: Integer; ovI: OleVariant; wordStyle: Style; begin for i := 1 to aWordDoc.Styles.Count do begin ovI := i; try wordStyle := aWordDoc.Styles.Item(ovI); except Continue;//skip if any error occurred. end; //do something with wordStyle end; end

  • Is the IP from the source or target in this System.Net.Sockets.SocketException?

    - by Jeremy Mullin
    I'm making an outbound connection using a DNS name to a server other than the localhost, and I get this exception: System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:5555 The text implies that the TARGET machine refused the connection, but the IP address and port are from the localhost, which is kind of confusing. So is that IP address really the outgoing IP and port, even though the exception was caused by the target refusing the connection? Or is the exception from the local firewall blocking the outgoing connection?

  • Django conditional template inheritance

    - by Ed
    I have template that displays object elements with hyperlinks to other parts of my site. I have another function that displays past versions of the same object. In this display, I don't want the hyperlinks. I'm under the assumption that I can't dynamically switch off the hyperlinks, so I've included both versions in the same template. I use an if statement to either display the hyperlinked version or the plain text version. I prefer to keep them in the same template because if I need to change the format of one, it will be easy to apply it to the other right there. The template extends framework.html. Framework has a breadcrumb system and it extends base.html. Base has a simple top menu system. So here's my dilemma. When viewing the standard hyperlink data, I want to see the top menu and the breadcrumbs. But when viewing the past version plain text data, I only want the data, no menu, no breadcrumbs. I'm unsure if this is possible given my current design. I tried having framework inherit the primary template so that I could choose to call either framework (and display the breadcrumbs), or the template itself, thus skipping the breadcrumbs, but I want framework.html available for other templates as well. If framework.html extends a specific template, I lose the ability to display it in other templates. I tried writing an if statement that would display a the top_menu block and the nav_menu block from base.html and framework.html respectively. This would overwrite their blocks and allow me to turn off those elements conditional on the if. Unfortunately, it doesn't appear to be conditional; if the block elements are in the template at all, surrounded by an if or not, I lose the menus. I thought about using {% include %} to pick up the breadcrumbs and a split out top menu. In that case though, I'll have to include it all the time. No more inheritance. Is this the best option given my requirement?

  • Getting results in a result set from dynamic SQL in Oracle

    - by msorens
    This question is similar to a couple others I have found on StackOverflow, but the differences are signficant enough to me to warrant a new question, so here it is: I want to obtain a result set from dynamic SQL in Oracle and then display it as a result set in a SqlDeveloper-like tool, just as if I had executed the dynamic SQL statement directly. This is straightforward in SQL Server, so to be concrete, here is an example from SQL Server that returns a result set in SQL Server Management Studio or Query Explorer: EXEC sp_executesql N'select * from countries' Or more properly: DECLARE @stmt nvarchar(100) SET @stmt = N'select * from countries' EXEC sp_executesql @stmt The question "How to return a resultset / cursor from a Oracle PL/SQL anonymous block that executes Dynamic SQL?" addresses the first half of the problem--executing dynamic SQL into a cursor. The question "How to make Oracle procedure return result sets" provides a similar answer. Web search has revealed many variations of the same theme, all addressing just the first half of my question. I found this post explaining how to do it in SqlDeveloper, but that uses a bit of functionality of SqlDeveloper. I am actually using a custom query tool so I need the solution to be self-contained in the SQL code. This custom query tool similarly does not have the capability to show output of print (dbms_output.put_line) statements; it only displays result sets. Here is yet one more possible avenue using 'execute immediate...bulk collect', but this example again renders the results with a loop of dbms_output.put_line statements. This link attempts to address the topic but the question never quite got answered there either. Assuming this is possible, I will add one more condition: I would like to do this without having to define a function or procedure (due to limited DB permissions). That is, I would like to execute a self-contained PL/SQL block containing dynamic SQL and return a result set in SqlDeveloper or a similar tool. So to summarize: I want to execute an arbitrary SQL statement (hence dynamic SQL). The platform is Oracle. The solution must be a PL/SQL block with no procedures or functions. The output must be generated as a canonical result set; no print statements. The output must render as a result set in SqlDeveloper without using any SqlDeveloper special functionality. Any suggestions?
