• IntelliJ IDEA non standard caret behaviour

  - by Vaat666

  I have an issue with IntelliJ IDEA when selecting a big amount of text, and I cannot find the parameter to set to change that. Here is an example of the situation: My caret is on line 3 I scroll with the mouse wheel towards line 300 I press ctrl + shift I press the left button of the mouse Such an action would result in the text from line 3 to 300 being selected in all common editors (even in MS-Word I think), but not in IntelliJ. Do you know how to set this right? Thanks!

• Python key word arguments

  - by pythonic metaphor

  I have several layers of function calls, passing around a common dictionary of key word arguments: def func1(**qwargs): func2(**qwargs) func3(**qwargs) I would like to supply some default arguments in some of the subsequent function calls, something like this: def func1(**qwargs): func2(arg = qwargs.get("arg", default), **qwargs) func3(**qwargs) The problem with this approach is that if arg is inside qwargs, a TypeError is raised with "got multiple values for keyword argument". I don't want to set qwargs["arg"] to default, because then func3 gets this argument without warrant. I could make a copy.copy of the qwargs and set "arg" in the copy, but qwargs could have large data structures in it and I don't want to copy them (maybe copy.copy wouldn't, only copy.deepcopy?). What's the pythonic thing to do here?

• Emacs shell output buffer height

  - by jimbo

  Hi , i have the following in my .emacs file(thanks to a SOer nikwin), which evaluates the current buffer content and displays the output in another buffer. (defun shell-compile () (interactive) (save-buffer) (shell-command (concat "python " (buffer-file-name)))) (add-hook 'python-mode-hook (lambda () (local-set-key (kbd "\C-c\C-c") 'shell-compile))) The problem is that the output window takes half the emacs screen. Is there any way to set the output windows's height to something smaller. I googled for 30mins or so and could not find anything that worked. Thanks in advance.

• vim command to restructure/force text to 80 columns

  - by wickedchicken

  I know there are ways to automatically set the width of text in vim using set textwidth (like http://stackoverflow.com/questions/235439/vim-80-column-layout-concerns). What I am looking for is something similar to = (the indent line command) but to wrap to 80. The use case is sometimes you edit text with textwidth and after joining lines or deleting/adding text it comes out poorly wrapped. Ideally, this command would completely reorganize the lines I select and chop off long lines while adding to short ones. An example: long line is long! short After running the command (assuming the wrap was 13 cols): long line is long! short If this isn't possible with a true vim command, perhaps there is a command-line program which does this that I can pipe the input to?

• 404 Error using Flash Builder 4 BlazeDS wizard

  - by codeflayer

  Hello again Stackoverflow! My issue this time around is trying to use the new DCD BlazeDS wizard in Flash Builder 4. If I set my project up as a combined Java/Flex app I am unable to connect to the RDS servlet using the wizard. I get a 404 error every time. I'm certain the service is set up correctly since my app can access the exposed java classes and BlazeMonster can see the exposed services. Is anyone else having this issue and if so has anyone found a work-around? I'd very much like to use the code generation features of the wizard for my project. Thanks as always, Codeflayer

  Can someone help me with Localization?

• Abstract Factory Using Generics: Is Explicitly Converting a Specified Type to Generic a Bad Practice

  - by Merritt

  The question's title says it all. I like how it fits into the rest of my code, but does it smell? public interface IFoo<T> { T Bar { get; set; } } public class StringFoo : IFoo<string> { public string Bar { get; set; } } public static class FooFactory { public static IFoo<T> CreateFoo<T>() { if (typeof(T) == typeof(string)) { return new StringFoo() as IFoo<T>; } throw new NotImplementedException(); } } UPDATE: this is sort of a duplicate of Is the StaticFactory in codecampserver a well known pattern?

  Hey, If I have the following: WSHttpBinding binding = new WSHttpBinding(); EndpointAddress endpoint = new EndpointAddress(new Uri("http://xxx:pppp/MyService")); MyServiceClient client = new MyServiceClient(binding, endpoint); How can I set the endpoint bindingConfiguration?

• How/is data shared between fastCGI processes?

  - by Josh the Goods

  I've written a simple perl script that I'm running via fastCGI on Apache. The application loads a set of XML data files which are used to lookup values based upon the the query parameters of an incoming request. As I understand it, if I want to increase the amount of concurrent requests my application can handle I need to allow fastCGI to spawn multiple processes. Will each of these processes have to hold duplicate copies of the XML data in memory? Is there a way to set things up so that I can have one copy of the XML data loaded in memory while increasing the capacity to handle concurrent requests?

• "SELECT TOP", "LEFT OUTER JOIN", "ORDER BY" gives extra rows

  - by Codesleuth

  I have the following Access query I'm running through OLE DB in .NET: SELECT TOP 25 tblClient.ClientCode, tblRegion.Region FROM (tblClient LEFT OUTER JOIN tblRegion ON tblClient.RegionCode = tblRegion.RegionCode) ORDER BY tblRegion.Region There are 431 records within tblClient that have RegionCode set to NULL. For some reason, the query above returns all these 431 records instead of the first 25. If I change the query to ORDER BY tblClient.Client (the name of the client) like so: SELECT TOP 25 tblClient.ClientCode, tblRegion.Region FROM (tblClient LEFT OUTER JOIN tblRegion ON tblClient.RegionCode = tblRegion.RegionCode) ORDER BY tblClient.Client I get the expected result set of 25 records, showing a mixture of region names and NULL values. Why is it that ordering by a field retrieved through a LEFT OUTER JOIN will the TOP clause not work?

• Scala Lift - Robust method to protect files from hotlinking

  - by sirjamm

  I'm attempting to implement a way to stop hotlinking and/or un-authorised access to resources within my app. The method I'm trying to add is something I've used before in PHP apps. Basically a session is set when the page is first called. The images are added to the page via the image tag with the session value as a parameter: <img src="/files/image/[handle]?session=12345" /> When the image is requested the script checks to see if the session is set and matches the provided value. If the condition is not met the serving page returns null. Right at the end to the code I unset the session so further requests from outside the scope of the page will return null. What would be the best implementation of this method within the lift framework? Thanks in advance for any help, much appreciated :)

• Perl TDS character sets

  - by skiphoppy

  I'm using the FreeTDS driver with DBD::Sybase, connecting to an MS SQL Server. When I query certain values of certain records, I get this error: DBD::Sybase::st fetchrow_arrayref failed: OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (9) NUMBER = (99) Server , database Message String: WARNING! Some character(s) could not be converted into client's character set. Unconverted bytes were changed to question marks ('?'). This seems to happen for records that contain special Windows character-set characters, such as curly quotes, copied and pasted from people's Outlook and Word messages. Unfortunately, I do not have any control of this database; sanitizing the input on the way in is obviously the way to go, but is not available to me. What FreeTDS settings do I need to change to be able to successfully query these records?

• null object reference in ScrollPane/endDrag() when scrollDrag=true

  - by SP

  Hello there. In my flash application, I've got multiple windows which use Scrollpanes. The scrollDrag property is set to true on these because I want that functionality. If I close (within my application) one of these 'windows' and open another, I seem to get a whole lot of this error showing up in my logs: TypeError: Error #1009: Cannot access a property or method of a null object reference. at fl.containers::ScrollPane/endDrag() Sometimes I get thousands of these, which I'm guessing is probably slowing my app down a bit, but otherwise is not causing a problem. Looking through the adobe code for scrollpane, endDrag is really simple: protected function endDrag(event:MouseEvent):void { stage.removeEventListener(MouseEvent.MOUSE_MOVE, doDrag); } The stage var is the only thing that could be null here. The only thing I can think to do is set scrollDrag=false before the window in my application closes so that nothing is listening for the event. Any other suggestions?

• Use trackball for scrolling in Android ListView

  - by gartenkralleb

  hi, i have a ListView, whose content should not be selectable. i set the ListView to choiceMode="none" and set a transparent listSelector. for touch mode it acts as desired. a problem is the use of the trackball. if i try to use it for scrolling, the scroll starts after the 10th push to "down". this is caused by the invisible listSelector, which scrolls down the list until the 10th list item is "invisibily" selected. i try to override dispatchTrackballEvent and do the scrolling with scrollBy, but i did not finished this approach yet, to have a look on alternative suggestions. is there a simple solution for my problem?

• Parameter for BPEL process

  - by Hubidubi

  Hi I use OpenESB + BPEL. I would like to use some parameter to set system specific settings (path, string constants, etc.). I tried to use a properties file that a simple java class should read up and use with this method (http://wiki.open-esb.java.net/Wiki.jsp?page=BPELSEHowToCallJavaMethods). The problem is that I can't create properties file in BPEL project (not supported). So I created a file by hand. But this file is not included in the deployed app. Is there any working solution for including property file or is there any other method to set parameters on BPEL process? Thanks, Hubidubi

• IIS7 + ASP.NET MVC Client Caching Headers Not Working

  - by Tobin Harris

  Hey folks I've deployed an ASP.NET MVC app on IIS7 and Windows Server 2008. I've read posts on here, and around the web, but can't get the darn client-side caching to work. I'm trying to cache everything in the /Content folder. So far I've select that folder in IIS manager, and set the appropriate HTTP Response Headers (under Common Headers). I've also checked the web.config file in the /Content folder and the values there are being set. All resources in /Content come back with this (from FireBug): Cache-Control no-cache, no-store, must-revalidate Pragma no-cache Content-Type image/png Expires -1 Last-Modified Sun, 11 Oct 2009 19:01:40 GMT Accept-Ranges bytes Etag "f318d643a54aca1:0" Server Microsoft-IIS/7.0 X-Powered-By ASP.NET Date Sun, 11 Oct 2009 20:40:01 GMT Content-Length 620 Note the Cache-Control and Expires values for this static image being requested. The site is currently compiled in Debug (this will change), but surely that wouldn't make a difference? Obviously I'm overlooking something, any ideas would be appreciated. Thanks

• fixed width bash prompt

  - by seaofclouds

  I'd like to set my bash prompt to a fixed width, and make up the difference in space before the $, so whether long or short, my prompt remains the same width: [name@host] ~/Directory/Dir...Another/LastDir $ [name@host] ~/Directory(branch) $ Currently, in a short directory path my prompt looks something like this: [name@host] ~/Directory(branch) $ a deeper directory path looks like this: [name@host] ~/Directory/Dir...Another/LastDir $ You can see I've truncated the PWD in the middle so I can see where the path begins, and where it ends. I'd like to make up the difference before the $. Here is my current prompt: # keep working directory to 30 chars, center tuncated prompt_pwd() { local pwd_symbol="..." local pwd_length=30 newPWD="${PWD/#$HOME/~}" [ ${#newPWD} -gt ${pwd_length} ] && newPWD=${newPWD:0:12}${pwd_symbol}${newPWD:${#newPWD}-15} } # set prompt prompt_color() { PROMPT_COMMAND='prompt_pwd;history -a;title_git' PS1="${WHITEONMAGENTA}[\u@\h]${MAGENTA} \w\$(parse_git_branch) ${MAGENTABOLD}\$${PS_CLEAR} " PS1=${PS1//\\w/\$\{newPWD\}} PS2="${WHITEONTEAL}>${PS_CLEAR} " } In my search, I found A Prompt the Width of Your Term which does do some fill, but couldn't get it working for this particular prompt.

• How do I add a combo box to a DataGrid?

  - by FigBug

  I want to add a ComboBox to a DataGrid. So far, the only way I've found to do it is like this: <mx:DataGridColumn headerText="Header" dataField="src" > <mx:itemRenderer> <mx:Component> <mx:ComboBox dataProvider="{data.srcChoices}" /> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> The problem is the initial value of the ComboBox isn't set correctly. If I hard code the choices, then the initial value is set correctly. I can't hard code the choices. Any idea what I should do?

• Using one sqlconnection/sqlcommand through 2 DB-bound methods

  - by dotnetdev

  I have a class with a method which gets data from a database through a SELECT stored proc. This method uses a SqlDbReader by returning ExecuteReader() on a SqlCommand. The connection and everything is made in this method, with fields (such as connection string) set as class level fields. I now need to populate an array based on the results of this query (so the columns of each row will go into the array with its own index). However, this query will not select all of the data from one table which is involved. I can write the queries to get what I need, but how can I use one connection throughout the class? If I instantiate the connection object and call Open() in the constructor, I get an exception @ runtime. I'm hoping for something like this: // At class level: sqlconn.Open(); // sqlcommand set up Method() { // Fire stored proc // Insert results in a collection } Method2() { // Pass same collection in (use same one), // Add new row columns into same collection } How can I do this with strict performance in mind? Thanks

• How do I pass a variable number of parameters along with a callback function?

  - by Bungle

  I'm using a function to lazy-load the Sizzle selector engine (used by jQuery): var sizzle_loaded; // load the Sizzle script function load_sizzle(module_name) { var script; // load Sizzle script and set up 'onload' and 'onreadystatechange' event // handlers to ensure that external script is loaded before dependent // code is executed script = document.createElement('script'); script.src = 'sizzle.min.js'; script.onload = function() { sizzle_loaded = true; gather_content(module_name); }; script.onreadystatechange = function() { if ((script.readyState === 'loaded' || script.readyState === 'complete') && !sizzle_loaded) { sizzle_loaded = true; gather_content(module_name); } }; // append script to the document document.getElementsByTagName('head')[0].appendChild(script); } I set the onload and onreadystatechange event handlers, as well as the sizzle_loaded flag to call another function (gather_content()) as soon as Sizzle has loaded. All of this is needed to do this in a cross-browser way. Until now, my project only had to lazy-load Sizzle at one point in the script, so I was able to just hard-code the gather_content() function call into the load_sizzle() function. However, I now need to lazy-load Sizzle at two different points in the script, and call a different function either time once it's loaded. My first instinct was to modify the function to accept a callback function: var sizzle_loaded; // load the Sizzle script function load_sizzle(module_name, callback) { var script; // load Sizzle script and set up 'onload' and 'onreadystatechange' event // handlers to ensure that external script is loaded before dependent // code is executed script = document.createElement('script'); script.src = 'sizzle.min.js'; script.onload = function() { sizzle_loaded = true; callback(module_name); }; script.onreadystatechange = function() { if ((script.readyState === 'loaded' || script.readyState === 'complete') && !sizzle_loaded) { sizzle_loaded = true; callback(module_name); } }; // append script to the document document.getElementsByTagName('head')[0].appendChild(script); } Then, I could just call it like this: load_sizzle(module_name, gather_content); However, the other callback function that I need to use takes more parameters than gather_content() does. How can I modify my function so that I can specify a variable number of parameters, to be passed with the callback function? Or, am I going about this the wrong way? Ultimately, I just want to load Sizzle, then call any function that I need to (with any arguments that it needs) once it's done loading. Thanks for any help!

• how to check only one item in checkedlistbox
