  • How to maintain tabs when pasting in Vim

    - by Ant Wilson
    I use the tab key to indent my python code in Vim, but whenever I copy and paste a block Vim replaces every tab with 4 spaces, which raises an IndentationError I tried setting :set paste as suggested in related questions but it makes no difference Other sites suggest pasting 'tabless' code and using the visual editor to re-indent, but this is asking for trouble when it comes to large blocks Are there any settings I can apply to vim to maintain tabs on copy/paste? Thanks for any help with this :) edit: I am copying and pasting within vim using the standard gnome-terminal techniques (ctrl+shift+c / mouse etc.) my .vimrc is: syntax on set ts=4 if has("terminfo") let &t_Co=8 let &t_Sf="\e[3%p1%dm" let &t_Sb="\e[4%p1%dm" else let &t_Co=8 let &t_Sf="\e[3%dm" let &t_Sb="\e[4%dm" endif I looked up that ts - Sets tab stops to n for text input, but don't know what value would maintain a tab character

  • Handling Character Encoding in URI on Tomcat

    - by ZZ Coder
    On the web site I am trying to help with, user can type in an URL in the browser, like following Chinese characters, http://localhost:8080?a=?? On server, we get GET /a=%E6%B5%8B%E8%AF%95 HTTP/1.1 As you can see, it's UTF-8 encoded, then URL encoded. We can handle this correctly by setting encoding to UTF-8 in Tomcat. However, sometimes we get Latin1 encoding on certain browsers, http://localhost:8080?a=ß turns into GET /a=%DF HTTP/1.1 Is there anyway to handle this correctly in Tomcat? Looks like the server has to do some intelligent guessing. We don't expect to handle the Latin1 correctly 100% but anything is better than what we are doing now by assuming everything is UTF-8. The server is Tomcat 5.5. The supported browsers are IE 6+, Firefox 2+ and Safari on iPhone.

  • Deselecting a form input and waiting for a function before submitting

    - by blcArmadillo
    I have a form with an input field where a user enters a unique identifier. I then have some jQuery code that upon the user moving away from the input field (blur) goes out and fetches details about the part and populates some fields on the page. The problem is if the user clicks the submit button before moving out of the input field the jQuery code never has a chance to load in the data and populate the necessary fields. Whats the best way to go about doing this? I thought about maybe setting the focus to body and then having an infinite loop that keeps checking the page until all fields that should be filled in have been filled in but I feel like some sort of event based solution would be better than unpredictable infinite loops. Any ideas?

  • Pygame program that can get keyboard input with caps

    - by None
    I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I relize this is because the program ignores shift input and instead writes the text if it's number is under 128. I have thought of setting a variable when shift is pressed then capitalizing if it was true, but string capitalization only woks on letters, not things like numbers or semicolons. Is there maybe a number I can add to the ascii number typed to modify it if shift is pressed, or something else?

  • jsFunction pass data to backingbean

    - by deilig
    I have a javascript that is calling a function addData(param1,param2,param3,param4) which is calling addClip at the end And I need to pass those to a backing bean. <a4j:form> <a4j:jsFunction name="addClip" action="#{backingBean.goGo}"> <a4j:actionparam name="param1" assignTo="#{backingBean.param1}"/> </a4j:jsFunction> </a4j:form> But I can't seem to pass any values to the backingbean. I've even tried setting a static value for the actionparam. But when I try to do a Systemout on the setParam1 method it only prints out null. Have I missed anything important?

  • Multithreading and booleans

    - by Ikaso
    Hi Everyone, I have a class that contains a boolean field like this one: public class MyClass { private boolean boolVal; public boolean BoolVal { get { return boolVal; } set { boolVal = value; } } } The field can be read and written from many threads using the property. My question is if I should fence the getter and setter with a lock statement? Or should I simply use the volatile keyword and save the locking? Or should I totally ignore multithreading since getting and setting boolean values atomic? regards,

  • belongs_to with a custom class_name not producing proper foreign key in Rails 3

    - by Tony
    I am updating an application to Rails 3 and I am having trouble creating a custom foreign key. I have something like this: class Product < ActiveRecord::Base belongs_to :owner, :class_name => 'User' ... end class User < ActiveRecord::Base has_many :products ... end class ProductsController < ApplicationController before_filter :authenticate_user! def index @products = current_user.products end end The view: <%- @products.each do |p| -%> <%= p.created_at %><br /> <%- end -%> I get this error in my Rails log: Mysql::Error: Unknown column 'products.user_id' in 'where clause': SELECT `products`.* FROM `products` WHERE (`products`.user_id = 1) It should see the belongs_to :owner and look for a foreign key called owner_id. I even tried explicitly setting the foreign key and that does not work. I also checked lighthouse for a possible Rails 3 bug but no luck.

  • how to write mute logic when mute state is unknown

    - by Delan Azabani
    I'm writing an indicator-sound clone for OSS4. Setting the volume works fine now, but I'm having trouble with the muting aspect of my program. A couple of facts about muting in OSS4: vmix doesn't have a mute (and we use vmix for volume control) also, the 'media keys' way of controlling volume doesn't set a mute control, but rather, volume = 0 The problem with this is, when reading the vmix volume and encountering zero, we don't know if the user has actually set it to zero, or has it set to some other value, but has mute on. How should I write my muting logic? git code, if that helps

  • Ad-Hoc mode and Cell (how does it work)?

    - by Ori Cohen
    hello, I am setting up a wireless Ad-Hoc network manually in linux using iwconfig and ifconfig. I have gotten everything working, and I think I understand it all except access point. The part that confused me is this: If I have essid='some_id', channel=11, Mode=Ad-Hoc and appropriate routing/ip on both laptops, why do I need to make sure the Cell is the same? I was under the impression that Ad-Hoc worked independently of the access point. I can easily get around this, I just use iwconfig wlan0 ap 00:00:00:00:00:01 Why is this necessary? I've been unable to find a good tutorial on this. If anyone can clear this up I'd appreciate it. Thanks

  • Custom size app screen on iPad

    - by mosdev
    I am trying to create a mid-size screen for my app on iPad. In didFinishLaunchingWithOptions(), I do this: CGRect winRect = CGRectMake(100,100,500,500); navController.view.frame = winRect; the screen comes up fine and I can click around and do stuff until the orientation changes. It takes the screen to original full size - how can I make it stick to my winRect frame? I tried setting the parentViewController.view.frame/view.frame to winRect in willRotateToInterfaceOrientation() but no good. Any ideas? Thanks.

  • Why is e.Item.DataItem null on ItemDataBound event when binding an asp:net Repeater to a Collection?

    - by Clean
    Hi, I'm trying to bind a collection implementing the ICollection, IEnumerable and IList interface to an asp.net repeater. The Collection is named CustomCollection. So I'm setting the datasource of the repeater to the collection, as follows: rptRepeater.DataSource = customCollection; rptRepeater.Databind(); Then, on the ItemDataBound event, I'm trying to access the DataItem object, as follow: void rptRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e){ object obj = e.Item.DataItem; // DataItem is null for some reason } For some reason the e.Item.DataItem object is null. Do anyone know why this is, and/or what I could do to get hold of the object in the collection that is to be databound to the repeater? Thanx!

  • How to set Atomikos to not write to console logs?

    - by peter
    Atomikos is quite verbose when used. There seems to be lots of INFO messages (mostly irrelevant for me) that the transaction manager writes out to the console. The setting in the transaction.properties that is suppose to control the level of messaging com.atomikos.icatch.console_log_level does not seem to have any effect, since even when set to WARN (or ERROR) the INFO messages are still logged. Also the log4j settings for com.atomikos and atomikos seem to be ignored. Does anyone manage to turn off the INFO logs on the console with Atomikos?. How? Thanks Peter

  • Program skips code after trying to parse XML in VB.NET

    - by Bead
    I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break. I tried catching exception but none are occurring, so I'm not sure what the problem is. Here is my code: Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream()) Dim xDoc As XmlDocument = New XmlDocument() xDoc.LoadXml(reader.ReadToEnd()) Dim omfg As String = xDoc.ChildNodes().Item(0).InnerText() Dim name As XmlNodeList = xDoc.GetElementsByTagName("div") Dim jj As Integer = name.Count For i As Integer = 0 To name.Count - 1 MessageBox.Show(name.Item(i).InnerText) Next i Anything after the "xDoc.LoadXml(reader.ReadToEnd())" doesn't execute.. Any ideas on this? My XML does have some whitespace at the beginning, I don't know if that is causing the problem...

  • Can't declare even the most simple class in PHP - Am I going insane?

    - by Phil
    I'm getting this error whenever I attempt to declare a class: Parse error: syntax error, unexpected T_VARIABLE, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home3/foundloc/public_html/booka/page2.php on line 7 (line 7 is the class declaration by the way).

I feel like this is one of those 'did you check if the TV is plugged in' type of issues....

  • Render view as string then redirect.

    - by JohnRudolfLewis
    In my ASP.NET MVC application, I would like my controller action to render a view to a string, send an email using that string as the body, then do a redirect. I've found several articles here on SO and elsewhere on how to render the view to a string. That part was easy. But when I attempt to perform the redirect, I get an HttpException: Cannot redirect after HTTP headers have been sent. I've tried setting Response.Buffer and Response.BufferOutput to true, I've tried Response.Clear, nothing seems to work. Is it possible to render a view to a string, then do a redirect?

  • Optimal preferences for prefix queries with Oracle catalog (CTXCAT) index

    - by nw
    The documentation for Oracle Text gives this example of a prefix/substring preference setting for context and catalog indexes: begin ctx_ddl.create_preference('mywordlist', 'BASIC_WORDLIST'); ctx_ddl.set_attribute('mywordlist','PREFIX_INDEX','TRUE'); ctx_ddl.set_attribute('mywordlist','PREFIX_MIN_LENGTH', '3'); ctx_ddl.set_attribute('mywordlist','PREFIX_MAX_LENGTH', '4'); ctx_ddl.set_attribute('mywordlist','SUBSTRING_INDEX', 'YES'); end; What I need to know is whether the substring_index attribute is necessary if I only ever issue prefix searches, such as: SELECT title FROM auction WHERE CATSEARCH(title, 'cam*', '') > 0; TITLE --------------- CANON CAMERA FUJI CAMERA NIKON CAMERA OLYMPUS CAMERA PENTAX CAMERA SONY CAMERA 6 rows selected

  • Explanation for expires header

    - by sushil bharwani
    I have a joomla application working on Apache.To improve site performace we have written a .htaccess file to root of the application with setting a far future expires header to all the static content. As desired first time the files load in fresh with 200 status code. when again click on the same link many of the files are served directly from cache. I need explanation for two things When i press f5 then a number of files load with 304 status code however i expected them to be coming directly from cache without hitting the server for a status header? When i close the browser and come back to the same page again i see the same thing happening a number of files load with 304 status code although i thought they will load directly from the browser cache? I understand that 304 also servs file from browser cache but i want to avoid the header communication between servers as my static files wont ever change. Also i want to add that my requests are over a https connection does that create any issue.

  • How do you change the style of cell in a JQuery.DataTable?

    - by Sephrial
    Hello fellow coders, I have a question about setting the style attributes for a data cell in the jQuery.DataTable. I was able to set the width for each column when initializing the dataTable using the following: oTable = $('#example').dataTable( { "aoColumns" : [ { sWidth: '40%' }, { sWidth: '60%' } ] } ); However, now I want to change the alignment for the second column like so: style="text-align: right;". I am adding rows dynamically: /* Global var for counter */ var giCount = 2; function fnClickAddRow() { oTable.fnAddData( [ 'col_1', 'col_2' ] ); giCount++; } Can you tell me how I can select the second cell of the added row after it's inserted? OR can you tell me how to set the style of the row before/during insertion? Any help would be greatly appreciated!

  • Assigning a default value to a final variable in case of an exception in Java

    - by frenetisch applaudierend
    Why won't Java let me assign a value to a final variable in a catch block after setting the value in the try block, even if it is not possible for the final value to be written in case of an exception. Here is an example that demonstrates the problem: public class FooBar { private final int foo; private FooBar() { try { int x = bla(); foo = x; // In case of an exception this line is never reached } catch (Exception ex) { foo = 0; // But the compiler complains // that foo might have been initialized } } private int bla() { // You can use any of the lines below, neither works // throw new RuntimeException(); return 0; } } The problem is not hard to work around, but I would like to understand why the compiler does not accept this. Thanks in advance for any inputs!

    hi im having trouble trying to get the following function to work.

When i use openquery i can overcome this by setting this: SET FMTONLY OFF. Does anyone know if there's a similar workaround for my problem?

  • How can I break into the development business scene if I'm the new kid on the block?

    - by Sergio Tapia
    I'm about 1 semester short of graduating from college with my Systems Engineer degree. I've started my own software development company here in a country in South America last week, and so far I managed to land myself a nice account. I have to build a simple enough program that will take me 6-7weeks to complete and I'll charge 2000$. 40% up front and the rest on completion. While this is great and I'm really excited about my first project (Hell it's a landmark for any professional!), I'm already setting my eye on landing projects that will be visible for other companies to see. I've spoken with many people in my trade around town and it seems there are two companies that manage the big accounts with other small companies scrounging around for the scraps. How can I break this so called fellowship that is pretty much a monopoly here? Any and all suggestions will be massively appreciated.

  • How does load balancing work with multiple server with multiple DBs

    - by Matt
    I guess what im looking for is a description on how this all works together. I'm used to setting up one server with maybe another server to handel the DB. My question is how does the load balancer work where do all the script(php,python) files go? If i make a change to one i have to rsync them to all the server that the balancer refers to? Also does each server need client side DB's installed so they can reference the DB's that are on other servers? If there is a site that explains all this i would be happy to read it.
