• Does Resharper 4.1 support both Camel Humps and normal selection modes?

  - by Jonathan Parker

  I've found the setting for Camel Humps in resharper: Resharper - Options - Editor - Use CamelHumps The problem is that I would still like to be able to use the normal selection mode (i.e. the default behaviour for CTRL+Arrow and CTRL+SHIFT+Arrow) as well as the CamelHumps mode. For example consider this variable: private int MyVeryLongCamelCaseName; Now if I want to copy the entire variable then I want the VS default behaviour for CTRL+SHIFT+Left-Arrow which is to select the entire variable if the cursor is on the M. However if I want to change the name to say MyExtremelyLongCamelCaseName then I would like the CamelHumps behaviour provided by Resharper. Is there any way to have both behaviours with different shortcuts?

• Split a html string in N parts

  - by Matt Brailsford

  Hi Guys, Does anybody have an example of spliting a html string (coming from a tiny mce editor) and splitting it into N parts using C#? I need to split the string evenly without splitting words. I was thinking of just splitting the html and using the HtmlAgilityPack to try and fix the broken tags. Though I'm not sure how to find the split point, as Ideally it should be based purley on the text rather than the html aswell. Anybody got any ideas on how to go about this? Many thanks Matt

• How do you use scripting language (PHP, Python, etc) to improve your productivity?

  - by Edwin

  Hi, I'm a Delphi developer on the Windows platform, recently read the PHP tutorial at W3CSchools, it looks interesting. We all know scripting languages are very good at web site development, but I also want to utilize it to improve my productivity or get some tedious tasks done quickly, maybe some quick-and-dirty string/file processing? How do you usually do with scripting languages apart from software development? And we need a responsive, decent IDE/editor in order to gain productivity when writing scripts for this purpose? Thanks for in advance!

• ASP.Net Response Filter Clashing with SharePoint 2010 Publishing Site Defaults

  - by Jason Weber

  Hello everyone, I'm debugging an HttpModule with an ASP.NET response filter. This dynamically rewrites portions of rendered SharePoint WCM pages. The publishing pages render fine in SP2007 on both Server 2003 and Server 2008. However the equivalent pages fail to render in SP2010 B2 on Server 2008 R2 / IIS7. The following error is returned by ASP.NET: Post cache substitution is not compatible with modules in the IIS integrated pipeline that modify the response buffers. Either a native module in the pipeline has modified an HTTP_DATA_CHUNK structure associated with a managed post cache substitution callback, or a managed filter has modified the response. This error is consistent with KB #2014472. However: Caching is disabled for anonymous & authenticated access at the site collection level There do not appear to be any Substitution controls on either the master or layout page The IIS 7 settings are all stock default This is happening e.g. on /pages/default.aspx. It seems likely I'm missing something cache related...but what?

• Visual Studio's CSS Intellisense - Absolute paths & MasterPage files

  - by Overflew

  Hi there. I've noticed that to get CSS-Intellisense working in VS, the paths have to be relative - Is this the case? However, it seems <link href="/resources/test.css" [...] /> is far more practical than <link href="resources/test.css" [...] /> I'm including the CSS in the master page, and don't see much good in including it as a content block, just to get the relative paths correct for each directory depth. I've had a quick try with inline code resolving the path, but no dice there either (for Intellisense). I feel I'm missing something fairly simple - What's the correct approach here to have CSS Intellisense work across the pages in the app during dev, and render fine in any deployed state? Cheers. (Note - I'm aware that a <% if (false) { % type hack is required for user controls)

• Editing remote files over SSH, using TextMate?

  - by Zachary Burt

  I LOVE using TextMate on my MacBook. It's great. Unfortunately, I want to edit some files directly on my dev server, since it's difficult to recreate the environment locally. I'm using Git, so one alternative is to just edit locally, git commit, git push, and then git merge, but that's kind of complicated every time I want to make a simple change. I'd rather just ... use another solution. One thing I tried is mounting a hard drive via MacFusion, and then loading that in an editor. But that's so freaking laggy/slow! Has anyone cooked up a better solution?

• Access Adobe InDesign files

  - by PeterMmm

  I need some directions for the following problem: I have a lot of InDesign files and i have to setup a process that will track if a certain paragraph or text block has changed between diferent versions of the file. If the text block has changed i want to extract that text block in a "portable" format (html, pdf, txt). Is there an Adobe product that would do that ? Is there any public API to access an InDesign file ? Is there the posibility to export InDesign to, say, html ?

• Alert show when extension of FileUpLoads are not allowed

  - by Vy Clarks

  I have a asp FileUpload control in my aspx page. And the code behind to check file's extension and then insert them into database: private string Write(HttpPostedFile file, string table) { string fileNameMain = Path.GetFileName(file.FileName); // check for the valid file extension string fileExtension = Path.GetExtension(fileNameMain).ToLower(); if (fileExtension.Equals(".pdf") || fileExtension.Equals(".doc")) { ...insert fileupload into database } else { LabelError.Text = "Extension of files are not allowed."; return null; } } With the code above, it checks the extension and then show the message "Extension of files are not allowed." in a LabelError if the fileupload is not allowed. Now, I'm required to do the "check-extension" in the other way: at the moment the client click and choose FileUpload, an alert show "Extension of files are not allowed.". I need a way to make an alert show at the momment the FileUpload choosed in browser. Help!!!!

• Visual Studio 2010 shortcut to select word / expression / line / section / method?

  - by Lernkurve

  There is a shortcut Ctrl+Shift+W to select the entire word at the current cursor position. Is there a similar shortcut that keeps expanding the selected region every time I apply it? I mean, is there a shortcut which selects the word when applied once (same as Ctrl+Shift+W) and selects the entire line when applied twice in a row and selects the entire block when applied three times etc., i.e. keeps expanding the selected region step by step? I remember seeing such a shortcut, but I don't remember whether it was for Visual Studio or some other editor.

• Running Sybase ISQL scripts from windows batch file

  - by user1328709

  I have already researched on this site as well as on google extensively for this. I have created a number of batch files that perform certain automated transactions(backups etc) on our production database. i want to further simplify my end of day processes by taking the dumps using a script that accepts input of some parameters. the script is able to login the isql prompt but unable to do the execution of the commands. @ECHO ***Started*** @ECHO Enter MonthDay(MMDD) SET /p md= @ECHO %md% mkdir \\10.20.1.17\arch\212%md%_banking set run=isql -Uuser -SORBITS -Ppass %run% @echo dump database banking to '/media/newArch/212%md%_banking/212%md%EOD_banking.dmp' with compression=5 @echo dump database master to '/media/newArch/212%md%_banking/212%md%EOD_master.dmp' @echo go pause I have been unsuccessful at putting these in a separate script file because the script itself uses a passed parameter. Please give me hints and links to Thanks

• Why is my iPhone SDK 3.2 iPad code showing a white screen?

  - by Anthony Glyadchenko

  I'm trying to get a UISplitViewController working with an iPad app. I have the table view controller linked up under the Master pane and a plain UIView under the Detail view. I also have [window addSubview:splitView.view]; in my code. For some reason I just get a white screen even though the table view controller code is properly coded and linked under my nib. Any help would be great! Thanks! Here's where you can find the code: http://drop.io/s28bu4t/asset/mydevice-hd-zip

• Is there a best-practice approach for internationalization of an application?

  - by Lee Warner

  We need to have our apps be translated into other languages. This entails renaming the .text properties of our visible controls as well as other literals found within our apps to whatever language we need to translate into. Is this something that can easily be accomplished with .resx files? I was thinking of creating a master resx key/value list where the key would be the fully qualified name of the control/variable/constant etc. and then refactor our apps to look into this file to get their values based on the cultureinfo found at runtime? Is there a standard or simpler approach to this problem?

• Design Question on when to save

  - by Ben

  Hi, I was just after peoples opinion on when the best time to save an object (or collection of objects) is. I appreciate that it can be completely dependent on the situation that you are in but here is my situation. I have a collection of objects "MyCollection" in a grid. You can open each object "MyObject" in an editor dialogue by double clicking on the grid. Selecting "Cancel" on the dialogue will back out any changes you have made, but should selecting "ok" commit those changes back to the database, or should they commit the changes on that object back to the collection and have a save method that iterates through the collection and saves all changed objects? If i have an object "MyParentObject", that contains a collection of childen "MyChildObjectCollection", none of the changes made to each "MyChildObject" would be commited to the database until the "MyParentObject" was saved - this makes sense. However in my current situation, none of the objects in the collection are linked, therefore should the "Ok" on the dialogue commit the changes to the database? Appreciate any opinions on this. Thanks

• python read utf8 text file problem

  - by cpps

  I have a problem with python about reading and print utf8 text file. I have a test.txt in utf8 encoding without BOM. This file has two characters in it: ?? The first character "?" is Chinese and the second "?" is Japanese. Now, When I use Ulipad (a python editor) to run the following code to read the txt file, and print these two characters. import codecs infile = "C:\\test.txt" f = codecs.open(infile, "r", "utf-8") s = f.read() print(s) I got this error, "UnicodeEncodeError: 'cp950' codec can't encode character '\u58f0' in position 1: illegal multibyte sequence" I found it caused from the second character "?" . But when I use the same code to test in python default GUI IDLE, it works to print the two characters with no error. So, how can I fix the problem. My running environment is python 3.1 , windows xp traditional Chinese.

• [java] Efficiency of while(true) ServerSocket Listen

  - by Submerged

  I am wondering if a typical while(true) ServerSocket listen loop takes an entire core to wait and accept a client connection (Even when implementing runnable and using Thread .start()) I am implementing a type of distributed computing cluster and each computer needs every core it has for computation. A Master node needs to communicate with these computers (invoking static methods that modify the algorithm's functioning). The reason I need to use sockets is due to the cross platform / cross language capabilities. In some cases, PHP will be invoking these java static methods. I used a java profiler (YourKit) and I can see my running ServerSocket listen thread and it never sleeps and it's always running. Is there a better approach to do what I want? Or, will the performance hit be negligible? Please, feel free to offer any suggestion if you can think of a better way (I've tried RMI, but it isn't supported cross-language. Thanks everyone

• About Android IDE

  - by licorna

  Right now I'm using Eclipse for Android development, but my computer is kind of old and I like responsive development environments. I've tried using VIM, Emacs and TextMate but I'm missing every feature in the Eclipse Android plugin: Auto generate R class Check for errors & warnings on code Auto completion Deploy to device or emulator Integrate with DDMS The list goes to infinity ... I know Eclipse is the best for what I want to do, but if I want to use any editor, what do you recommend to achieve a not so frustrating Android development experience?

• HMM for perspective estimation in document image, can't understand the algorithm

  - by maximus

  Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about Hidden Markov Models and I know that it uses probabilities that must be known. But in this algorithm I can't understand, if they use HMM, how do they get those probabilities (probability of changing the state from S1 to another state for example S2)? I didn't find anything about training there also in that paper. So, if somebody understands it, please tell me. Also is it possible to use HMM without knowing the state change probabilities?

• Advice needed from PHP/Cake PHP expert

  - by Hiro

  I'm very new to programming (besides SQL and databases), but I ultimately want to master Cake PHP for web development. Now, given how new I am, I'm rather lost as to how I get started. Down the road, I want to use MVC framework so that I help myself be disciplined in the way I build. However, I know basic knowledge of PHP and OOP PHP are required. So my question is this: what are the right steps to mastering Cake PHP? I don't want to skip critical phases of learning before learning to Cake PHP. At the same time, I don't want to spend more time than required learning PHP if I can learn it directly through Cake PHP knowledge. Any advice would be appreciated.

• How do you get the glyph for a character encoded as '&#333;' from a utf-8 encoded database field usi

  - by AE

  I have a MySQL database table with a collation of 'utf8_general_ci' and the value in the field is: x & #299; bán yá wén (without the spaces). When this is converted (for example by StackOverflow's editor) it looks like this: xī bán yá wén where the second character looks like a lower case i with a bar over the top. In PHP, what function converts the & #299 ; entity into the ī character? I've tried using html_entity_decode($str,ENT_COMPAT,'UTF-8'), however I get characters like the following: yÄ«n wén or zhÅ•ng wén I'm pretty sure there's something I don't understand about the decoding, which is why I'm using the wrong function. Can anyone shed some light on how to get the single character glyph that's represented by the entity & #299 and similar high-number characters above 255? Many thanks, AE

• Latex change color of intext citing with hyperref package and natbib

  - by Thomas

  I am using the natbib and hyperref package in conjunction with my latex document. I would like to change to the color of my hyppereferenced citations (the box around the citation) from the ugly baseline green to a more muted (violet or navy blue). However, in using the suggested code to do this, I can not get the citation link colors to change. My code is as follows \usepackage[usenames,dvipsnames]{color} \usepackage[round]{natbib} \usepackage[hyperfootnotes=false]{hyperref} \usepackage[hyperfootnotes=false]{hyperref} \hypersetup{ colorlinks=false, citecolor=Violet, linkcolor=Red, urlcolor=Blue} \begin{document} \bibliographystyle{apsr} \bibliography{exp_final} \end{document} However, when I compile (I compiled multiple times to make sure) this my pdf file looks the same as if I had excluded the formatting in the hypersetup (still the same ugly green). I would also like to box the footnote citations as well. Any ideas or help would be much appreciated. Thanks, Thomas

• TreeView nodes always have .Checked=true on postback even when not checked in UI

  - by GISmatters

  I have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled. No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine. Thanks in advance for any helpful comments or questions, Chris

• Sql server table can be queried but not updated

  - by Nigel

  i have a table which was always updatable before, but then suddenly i can no longer update the any of the columns in the table. i can still query the whole table and the results come back very fast, but the moment i try to update a column in the table, the update query simply stalls and does nothing. i tried using select req_transactionUOW from master..syslockinfo where req_spid = -2 to see if some orphaned transaction was locking the table, but it returns no results. i can't seems to find signs of my table being locked, but simply cannot update it. any clues as to how to fix the table or whatever state it is in?

• Mixing a4 and a3 in one Latex file

  - by jorgusch

  Hello, I am finishing my thesis and have a large appendix. Some tables only look good, if first done on a3 and then (paper)printed on a4. Anyhow, working all the files seperalty is fine, but I struggle to compile all in one. I use the geometry package and start the document with: \usepackage[a4paper,left=30mm,right=20mm,top=20mm, bottom=20mm]{geometry} For the appendix, I want to include the table and use \newgeometry{a3paper,left=25mm,right=15mm, top=15mm, bottom=15mm} However, the command is completely ignored and I can read "a3paper,left=25mm,right=15mm, top=15mm, bottom=15mm" above the table. What did I miss? Is it even possible? If not, how do I get the numbers right, if I have to include it as a pdf (which works)? Thanks!
