• Recover files from corrupt filesystem

  - by Emile 81

  My situation: I have an older 80GB IDE internal hdd, with a few files on that I would like very much to recover: some word documents some latex documents (text files) and pictures (png, jpg, eps files) some other text documents and visual studio project files I had backed them (not the latex ones though) up using svn, but have not committed lately, and would loose a lot of work if I cant recover. the hdd seems to have lost its filesystem, i have no idea how it came about. I know it has/had 3 NTFS partitions, i know the files i want are on the second or third partition. I read http://superuser.com/questions/81877/recover-hard-disk-data Partition Find and Mount did not see all the partitions using intelligent scan TestDisk does (i think), I followed the step by step instructions here, but when I try to list the files it says: "Can't open filesystem, filesystem seems damaged." I'm not sure how to proceed here, as TestDisks wiki does not contain this error message afaik. I don't know if the hdd is gonna fail, or some prog has caused the filesystem to be corrupt, the hdd doesnt make a sound, so i guess that's good. I would like some guidance so I don't accidentally cause more damage. (eg. is it ok to let testdisk write the filesystem to disk? I'm pretty the partitions are listed ok, but not 100%)

• DNN: Registered Mark changing to Question Mark

  - by coultertech

  I am having a problem with registered marks in the HTML module.  We need to use the Registered Trademark symbol (®) but some of them are being changed to question marks.  I can find no ryme or reason behind which change and which remain correct.  I have tried a number of things to fix this issue including the following: Using ® and ® using ® copy and paste of ® in both source and non source and using the "insert special character" from the RTE menu Some of the symbols remain but most revert back to question marks.  If i'm in edit mode, the questions marks change back to the registered mark.  Also sometimes the first time viewing the page not logged in or in view mode, they will look fine. But as soon as I got to edit mode or a new page then go back, they change back to question marks.  I am out of idea as to why this is happening. You can see the page at: http://fasttracsc.twif.net/AboutFastTracSC.aspx  Anywhere you see Fasttrac? it should be Fasttrac® Any help anyone can provide would be much appreciated. Thanks in advance.

• How to override ATTR_DEFAULT_IDENTIFIER_OPTIONS in Models in Doctrine?

  - by user309083

  Here someone explained that setting a 'primary' attribute for any row in your Model will override Doctrine_Manager's ATTR_DEFAULT_IDENTIFIER_OPTIONS attribute: http://stackoverflow.com/questions/2040675/how-do-you-override-a-constant-in-doctrines-models This works, however if you have a many to many relation whereby the intermediate table is created, even if you have set both columns in the intermediate to primary an error still results when Doctrine tries to place an index on the nonexistant 'id' column upon table creation. Here's my code: //Bootstrap // set the default primary key to be named 'id', integer, 4 bytes Doctrine_Manager::getInstance()->setAttribute( Doctrine_Core::ATTR_DEFAULT_IDENTIFIER_OPTIONS, array('name' => 'id', 'type' => 'integer', 'length' => 4)); //User Model class User extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('users'); } public function setUp() { $this->hasMany('Role as roles', array( 'local' => 'id', 'foreign' => 'user_id', 'refClass' => 'UserRole', 'onDelete' => 'CASCADE' )); } } //Role Model class Role extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('roles'); } public function setUp() { $this->hasMany('User as users', array( 'local' => 'id', 'foreign' => 'role_id', 'refClass' => 'UserRole' )); } } //UserRole Model class UserRole extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('roles_users'); $this->hasColumn('user_id', 'integer', 4, array('primary'=>true)); $this->hasColumn('role_id', 'integer', 4, array('primary'=>true)); } } Resulting error: SQLSTATE[42000]: Syntax error or access violation: 1072 Key column 'id' doesn't exist in table. Failing Query: "CREATE TABLE roles_users (user_id INT UNSIGNED NOT NULL, role_id INT UNSIGNED NOT NULL, INDEX id_idx (id), PRIMARY KEY(user_id, role_id)) ENGINE = INNODB". Failing Query: CREATE TABLE roles_users (user_id INT UNSIGNED NOT NULL, role_id INT UNSIGNED NOT NULL, INDEX id_idx (id), PRIMARY KEY(user_id, role_id)) ENGINE = INNODB I'm creating my tables using Doctrine::createTablesFromModels();

• iPhone SDK : UIImageView - Collapsing animation

  - by chris.o.

  Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing is not the part that I want. The image is arranged so that from L to R, a white to red color gradient occurs. The right side (about 20 pixels) is solid red and is the part I want to show when the bar is "collapsed". I'm trying to extend the image out by about 100 pixels to its full width. I referenced the "Buy Now" button example for my code as it seemed relevant" http://stackoverflow.com/questions/1669804/uibutton-appstore-buy-button-animation My code: [UIView beginAnimations:@"barAnimation" context:nil]; [UIView setAnimationDuration:0.6]; CGRect barFrame = bookBar.bounds; if (fExtendBar) { barFrame.origin.x -= 100; barFrame.size.width += 100; } else { barFrame.origin.x += 100; barFrame.size.width -= 100; } bookBar.frame = barFrame; [UIView commitAnimations]; I feel like this should be possible, maybe by setting an "offsetOfImage" to display in the UIImageView, but I can't seem to make it work. Also, I've noticed that the behavior is kind of consistent with what happens in Interface Builder when you resize an image. Then again, I would think there would be a way to override this behavior programmatically. Any suggestions (including other approaches) are welcome. Thanks, chris.o.

• Scrolling a Canvas smoothly in Android

  - by prepbgg

  I'm new to Android. I am drawing bitmaps, lines and shapes onto a Canvas inside the OnDraw(Canvas canvas) method of my view. I am looking for help on how to implement smooth scrolling in response to a drag by the user. I have searched but not found any tutorials to help me with this. The reference for Canvas seems to say that if a Canvas is constructed from a Bitmap (called bmpBuffer, say) then anything drawn on the Canvas is also drawn on bmpBuffer. Would it be possible to use bmpBuffer to implement a scroll ... perhaps copy it back to the Canvas shifted by a few pixels at a time? But if I use Canvas.drawBitmap to draw bmpBuffer back to Canvas shifted by a few pixels, won't bmpBuffer be corrupted? Perhaps, therefore, I should copy bmpBuffer to bmpBuffer2 then draw bmpBuffer2 back to the Canvas. A more straightforward approach would be to draw the lines, shapes, etc. straight into a buffer Bitmap then draw that buffer (with a shift) onto the Canvas but so far as I can see the various methods: drawLine(), drawShape() and so on are not available for drawing to a Bitmap ... only to a Canvas. Could I have 2 Canvases? One of which would be constructed from the buffer bitmap and used simply for plotting the lines, shapes, etc. and then the buffer bitmap would be drawn onto the other Canvas for display in the View? I should welcome any advice! Answers to similar questions here (and on other websites) refer to "blitting". I understand the concept but can't find anything about "blit" or "bitblt" in the Android documentation. Are Canvas.drawBitmap and Bitmap.Copy Android's equivalents?

• Parsing and getting specific values from CSV string

  - by Amit Ranjan

  I am having a string in CSV format. Please see my earlier question http://stackoverflow.com/questions/2865861/parsing-csv-string-and-binding-it-to-listbox I can add new values to it by some mechanism. Everything will be same except the new values will have numeric part = 0. Take example I have this exsiting CSV string 1 , abc.txt , 2 , def.doc , 3 , flyaway.txt Now by some mechanism i added two more files Superman.txt and Spiderman.txt to the existing string. Now it became 1 , abc.txt , 2 , def.doc , 3 , flyaway.txt, 0, Superman.txt, 0 , Spiderman.txt What i am doing here is that this csv string is paased into SP where its splitted and inserted to db. So for inserting I have to take the files with numeric part 0 only rest will be omiited .Which will be further then converted into CSV string Array will look like this str[0]="1" str[1]="abc.txt" str[2]="2" str[3]="def.doc " str[4]="3" str[5]="flyaway.txt" str[6]="0" str[7]="Superman.txt" str[8]="0" str[9]="Spiderman.txt" So at last i want to say my input will be 1 , abc.txt , 2 , def.doc , 3 , flyaway.txt, 0, Superman.txt, 0 , Spiderman.txt Desired Output: 0, Superman.txt, 0 , Spiderman.txt

• InvalidOperationException (Lambda parameter not in scope) when trying to Compile a Lambda Expression

  - by Moshe Levi

  Hello, I'm writing an Expression Parser to make my API more refactor friendly and less error prone. basicaly, I want the user to write code like that: repository.Get(entity => entity.Id == 10); instead of: repository.Get<Entity>("Id", 10); Extracting the member name from the left side of the binary expression was straight forward. The problems began when I tried to extract the value from the right side of the expression. The above snippet demonstrates the simplest possible case which involves a constant value but it can be much more complex involving closures and what not. After playing with that for some time I gave up on trying to cover all the possible cases myself and decided to use the framework to do all the heavy lifting for me by compiling and executing the right side of the expression. the relevant part of the code looks like that: public static KeyValuePair<string, object> Parse<T>(Expression<Func<T, bool>> expression) { var binaryExpression = (BinaryExpression)expression.Body; string memberName = ParseMemberName(binaryExpression.Left); object value = ParseValue(binaryExpression.Right); return new KeyValuePair<string, object>(memberName, value); } private static object ParseValue(Expression expression) { Expression conversionExpression = Expression.Convert(expression, typeof(object)); var lambdaExpression = Expression.Lambda<Func<object>>(conversionExpression); Func<object> accessor = lambdaExpression.Compile(); return accessor(); } Now, I get an InvalidOperationException (Lambda parameter not in scope) in the Compile line. when I googled for the solution I came up with similar questions that involved building an expression by hand and not supplying all the pieces, or trying to rely on parameters having the same name and not the same reference. I don't think that this is the case here because I'm reusing the given expression. I would appreciate if someone will give me some pointers on this. Thank you.

• Remove All Nodes with (nodeName = "script") from a Document Fragment *before placing it in dom*

  - by Matrym

  My goal is to remove all <[script] nodes from a document fragment (leaving the rest of the fragment intact) before inserting the fragment into the dom. My fragment is created by and looks something like this: range = document.createRange(); range.selectNode(document.getElementsByTagName("body").item(0)); documentFragment = range.cloneContents(); sasDom.insertBefore(documentFragment, credit); document.body.appendChild(documentFragment); I got good range walker suggestions in a separate post, but realized I asked the wrong question. I got an answer about ranges, but what I meant to ask about was a document fragment (or perhaps there's a way to set a range of the fragment? hrmmm). The walker provided was: function actOnElementsInRange(range, func) { function isContainedInRange(el, range) { var elRange = range.cloneRange(); elRange.selectNode(el); return range.compareBoundaryPoints(Range.START_TO_START, elRange) <= 0 && range.compareBoundaryPoints(Range.END_TO_END, elRange) >= 0; } var rangeStartElement = range.startContainer; if (rangeStartElement.nodeType == 3) { rangeStartElement = rangeStartElement.parentNode; } var rangeEndElement = range.endContainer; if (rangeEndElement.nodeType == 3) { rangeEndElement = rangeEndElement.parentNode; } var isInRange = function(el) { return (el === rangeStartElement || el === rangeEndElement || isContainedInRange(el, range)) ? NodeFilter.FILTER_ACCEPT : NodeFilter.FILTER_SKIP; }; var container = range.commonAncestorContainer; if (container.nodeType != 1) { container = container.parentNode; } var walker = document.createTreeWalker(document, NodeFilter.SHOW_ELEMENT, isInRange, false); while (walker.nextNode()) { func(walker.currentNode); } } actOnElementsInRange(range, function(el) { el.removeAttribute("id"); }); That walker code is lifted from: http://stackoverflow.com/questions/2690122/remove-all-id-attributes-from-nodes-in-a-range-of-fragment PLEASE No libraries (ie jQuery). I want to do this the raw way. Thanks in advance for your help

• Loading JNI lib on OSX?

  - by Clinton

  Background So I am attempting to load a jnilib (specifically JOGL) into java on OSX at runtime. I have been following along the relevant stackoverflow questions: Maven and the JOGL Library Loading DLL in Java - Eclipse - JNI How to make a jar file that include all jar files The end goal for me is to package platform specific JOGL files into a jar and unzip them into a temp directory and load them at start-up. I worked my problem back to simply attempting to load JOGL using hard-coded paths: File f = new File("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl.jnilib"); System.load(f.toString()); f = new File ("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl_awt.jnilib"); System.load(f.toString()); I get the following exception when attempting to use the JOGL API: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path But when I specify java.library.path by adding the following JVM option: -Djava.library.path="/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/" Everything works fine. Question Is it possible use System.load (or some other variant) on OSX as a replacement for -Djava.library.path that is invoked at runtime?

• Removing and then adding MKAnnotations to a MapView is leaving me with a blank MapView

  - by Chris McCall

  A followup to this quesiton: http://stackoverflow.com/questions/2944581/forcing-reload-of-view-when-returning-from-flipsideview-of-utility-application When returning from the flipside view, I'm calling NSArray *annotations = [NSArray arrayWithArray:[mapView annotations]]; [mapView removeAnnotations:annotations]; To remove all the pins from the map (let me know if this isn't the best way to do this). Then: for(Hole *hole in fetchedObjects) { double latitude = [hole.Latitude doubleValue]; cord.latitude = latitude; double longitude = [hole.Longitude doubleValue]; cord.longitude = longitude; WellPlaceMark *placemark = [[WellPlaceMark alloc] initWithCoordinate:cord withWellType:[NSString stringWithString: hole.WellType]]; [mapView addAnnotation:placemark]; } Plus: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{ MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; if ([annotation isKindOfClass:[MKUserLocation class]]) return nil; if([annotation isKindOfClass:[WellPlaceMark class]]) { ... } annView.animatesDrop=FALSE; return annView; } All of this code seems to be called in the debugger, but when it's finished, I'm presented with a blank map. I've tried zooming out and the pins are nowhere. The map loads up fine on the first try, but once I call removeAnnotations, they never return.

• Threading 101: What is a Dispatcher?

  - by Water Cooler v2

  Once upon a time, I remembered this stuff by heart. Over time, my understanding has diluted and I mean to refresh it. As I recall, any so called single threaded application has two threads: a) the primary thread that has a pointer to the main or DllMain entry points; and b) For applications that have some UI, a UI thread, a.k.a the secondary thread, on which the WndProc runs, i.e. the thread that executes the WndProc that recieves messages that Windows posts to it. In short, the thread that executes the Windows message loop. For UI apps, the primary thread is in a blocking state waiting for messages from Windows. When it recieves them, it queues them up and dispatches them to the message loop (WndProc) and the UI thread gets kick started. As per my understanding, the primary thread, which is in a blocking state, is this: C++ while(getmessage(/* args &msg, etc. */)) { translatemessage(&msg, 0, 0); dispatchmessage(&msg, 0, 0); } C# or VB.NET WinForms apps: Application.Run( new System.Windows.Forms() ); Is this what they call the Dispatcher? My questions are: a) Is my above understanding correct? b) What in the name of hell is the Dispatcher? c) Point me to a resource where I can get a better understanding of threads from a Windows/Win32 perspective and then tie it up with high level languages like C#. Petzold is sparing in his discussion on the subject in his epic work. Although I believe I have it somewhat right, a confirmation will be relieving.

• SQL query to count and list the different counties per zip code

  - by Chris

  I have a sql server 2005 table called ZipCode, which has all the US ZIPs in it. For each entry, it lists the zip, county, city, state, and several other details. Some zipcodes span multiple cities and some even span multiple counties. As a result, some zipcodes appear many times in the table. I am trying to query the table to see which zipcodes go across multiple counties. This is what I have so far: select zipcode, count(zipcode) as total, county, state from zipcode group by zipcode, county, state order by zipcode Of 19248 records in the result set, here are the first several records returned: zipcode total county state 00501 2 SUFFOLK NY 00544 2 SUFFOLK NY 00801 3 SAINT THOMAS VI 00802 3 SAINT THOMAS VI 00803 3 SAINT THOMAS VI 00804 3 SAINT THOMAS VI 00805 1 SAINT THOMAS VI 00820 2 SAINT CROIX VI 00821 1 SAINT CROIX VI 00822 1 SAINT CROIX VI 00823 2 SAINT CROIX VI 00824 2 SAINT CROIX VI In this particular example, each zip with a total of two or more happens to be in the table more than once, and it's because the "cityaliasname" (not shown) or some other column differs. But I just want to know which zips are in there more than once because the county column differs. I searched before posting this and I found many questions about counting records but I could not figure out how to apply them to my problem. Please forgive me if there is already a question whose answer applies to this question.

• Embeddable forum software

  - by Rented

  I am in the planning stages of a specific subject matter community web site, and one feature I feel is required is that of member discussions. However, not in a typical forum style. For example, I don't want the members to have to navigate away from their own "user space" in order to discuss a topic. I think it is best described with an analogous example. Lets say the site is for literature buffs, and each member has a set of pages for keeping notes, progress, questions, etc. on books they are studying/reading. So Joe will have one page for Great Expectations, another for Hamlet, a third for I, Robot, and so forth. Likewise, Jane will have a page for Don Quixote, Lord of the Flies, and also I, Robot. Now, wouldn't it be nice if Joe and Jane could discuss I, Robot from within their own respective pages? Now, at first thought, roll your own seems like the way to go. However, once we start getting into issues such as spam blocking, banning, ratings, pruning, archiving, flooding and so on, well "roll your own" doesn't sound too appealing anymore. Also, I have next to zero experience with forum software. So I'm looking for forum software that has an extensive API or is generally very integration-friendly. I would like to be able to create user groups, topics, permissions, etc. programmatically,as well as the obvious user authentication (most seem open in that respect). The site will most probably be built with Java. Tangler seems like a descent option, but it seems less mature than what I'd prefer.

• DataGridView not displaying data in ToolStripDropDown

  - by jblaske

  I'm utilizing the code posted by Jesper Palm here: http://stackoverflow.com/questions/280891/make-user-control-display-outside-of-form-boundry /// <summary> /// A simple popup window that can host any System.Windows.Forms.Control /// </summary> public class PopupWindow : System.Windows.Forms.ToolStripDropDown { private System.Windows.Forms.Control _content; private System.Windows.Forms.ToolStripControlHost _host; public PopupWindow(System.Windows.Forms.Control content) { //Basic setup... this.AutoSize = false; this.DoubleBuffered = true; this.ResizeRedraw = true; this._content = content; this._host = new System.Windows.Forms.ToolStripControlHost(content); //Positioning and Sizing this.MinimumSize = content.MinimumSize; this.MaximumSize = content.Size; this.Size = content.Size; content.Location = Point.Empty; //Add the host to the list this.Items.Add(this._host); } } I've translated it to VB: Public Class PopupWindow Inherits System.Windows.Forms.ToolStripDropDown Private _content As System.Windows.Forms.Control Private _host As System.Windows.Forms.ToolStripControlHost Public Sub New(ByVal content As System.Windows.Forms.Control) Me.AutoSize = False Me.DoubleBuffered = True Me.ResizeRedraw = True Me._content = content Me._host = New System.Windows.Forms.ToolStripControlHost(content) Me.MinimumSize = content.MinimumSize Me.MaximumSize = content.MaximumSize Me.Size = content.Size content.Location = Point.Empty Me.Items.Add(Me._host) End Sub End Class It works great with a PictureBox showing its information. But for some reason I cannot get the DataGridView to display anything when it is in the popup. If I pull the grid out of the popup it displays all of its information fine. If I pause during debug, the grid shows that it has all the data in it. It's just not displaying anything. Does anybody have any ideas?

• How do you host multiple public facing websites on a VPS?

  - by Petras

  We host about 30 websites using typical shared hosting plans using ASP.NET and SQL 2000/2005/2008. I am now wondering about hosting all of these websites using our own virtual private server such as http://www.crystaltech.com/vps.aspx This is clearly cheaper but comes with a lot of questions I need answers to: Is the risk of having to keep this VPS server up and running worth it? Until now, the host provider has managed the server and we have not had to worry about crashes, downtime, software patches etc. We are not server administrators, we are programmers, so this is not really our expertise. On the other hand, it may not be hard to learn. When we make a website live, we log in to a domain management control panel and change the primary and secondary name servers to point to our shared web host: Eg ns1.sharedwebhost.com and ns2.sharedwebhost.com These name servers are going to have to change when we have a VPS. I don’t understand anything about how to set this up. Is there some useful info anyone could direct me to? Or is there software we need to install to make the primary and secondary name servers work on our VPS? The control panel we have for shared hosting comes with DNS management like this: What software would I need to install to create this for each site we host at a VPS? The control panel we have for shared hosting also comes with a POP email interface that allows email addresses to be added easily: Is this something that can be easily set up at a VPS so clients can manage their own email addresses? Is there software we need to install to make this work?

• WPF Memory Leak on XP (CMilChannel, HWND)

  - by vanja.

  My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

• Rails test db doesn't persist record changes

  - by nathan.f77

  I've been trying to solve a problem for a few weeks now. I am running rspec tests for my Rails app, and they are working fine except for one error that I can't seem get my head around. I am using MySQL with the InnoDB engine. I have set config.use_transactional_fixtures = true in spec_helper.rb I load my test fixtures manually with the command rake spec:db:fixtures:load. The rspec test is being written for a BackgrounDRb worker, and it is testing that a record can have its state updated (through the state_machine gem). Here is my problem: I have a model called Listings. The rspec test calls the update_sold_items method within a file called listing_worker.rb. This method calls listing.sell for a particular record, which sets the listing record's 'state' column to 'sold'. So far, this is all working fine, but when the update_sold_items method finishes, my rspec test fails here: listing = Listing.find_by_listing_id(listing_id) listing.state.should == "sold" expected: "sold", got: "current" (using ==) I've been trying to track down why the state change is not persisting, but am pretty much lost. Here is the result of some debugging code that I placed in the update_sold_items method during the test: pp listing.state # => "current" listing.sell! listing.save! pp listing.state # => "sold" listing.reload pp listing.state # => "current" I cannot understand why it saves perfectly fine, but then reverts back to the original record whenever I call reload, or Listing.find etc. Thanks for reading this, and please ask any questions if I haven't given enough information. Thanks for your help, Nathan B P.S. I don't have a problem creating new records for other classes, and testing those records. It only seems to be a problem when I am updating records that already exist in the database.

• Fastest way to remove non-numeric characters from a VARCHAR in SQL Server

  - by Dan Herbert

  I'm writing an import utility that is using phone numbers as a unique key within the import. I need to check that the phone number does not already exist in my DB. The problem is that phone numbers in the DB could have things like dashes and parenthesis and possibly other things. I wrote a function to remove these things, the problem is that it is slow and with thousands of records in my DB and thousands of records to import at once, this process can be unacceptably slow. I've already made the phone number column an index. I tried using the script from this post: http://stackoverflow.com/questions/52315/t-sql-trim-nbsp-and-other-non-alphanumeric-characters But that didn't speed it up any. Is there a faster way to remove non-numeric characters? Something that can perform well when 10,000 to 100,000 records have to be compared. Whatever is done needs to perform fast. Update Given what people responded with, I think I'm going to have to clean the fields before I run the import utility. To answer the question of what I'm writing the import utility in, it is a C# app. I'm comparing BIGINT to BIGINT now, with no need to alter DB data and I'm still taking a performance hit with a very small set of data (about 2000 records). Could comparing BIGINT to BIGINT be slowing things down? I've optimized the code side of my app as much as I can (removed regexes, removed unneccessary DB calls). Although I can't isolate SQL as the source of the problem anymore, I still feel like it is.

• thesis in LaTeX without memoir

  - by yCalleecharan

  Hi, I'm preparing a thesis report in LaTeX. I don't want to use the memoir class as I would like total control. I have two questions: My thesis consists of an introduction and then a series of articles pasted one after the other. Thus each article has its own abstract, introduction, etc... and a bibliography at its end. I understand that perhaps a package like multibib can help when we have multiple bibliographies. The idea that I came with is to write each article separately and then use pdfpages to combine the final document. Long time ago dvi files concatenation was popular but with graphics I think that pdfpages is better. I saw that another package exists, named combine which can help with what I am doing. I'm still exploring my options. Any suggestions? If I decide to use a book class instead to make my thesis resemble more into a book-like format which is better, then using the book class format gives me section headings like 0.1 Introduction with the leading 0. This 0 doesn't show in the article class format. How to change this default book class numbering format so that I'll have e.g. 1. Introduction? Thanks a lot...

  I have a WCF REST Service which accepts a JSON string One of the parameters is a large string of numbers This causes the following error - which is visible by tracing and using SVC Trace Viewer There was an error deserializing the object of type CarConfiguration. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Now I've read all sorts of articles advising how to rectify this All of them recommend increasing various config settings on the server and client e.g. http://stackoverflow.com/questions/65452/error-serializing-string-in-webservice-call http://bloggingabout.net/blogs/ramon/archive/2008/08/20/wcf-and-large-messages.aspx http://social.msdn.microsoft.com/Forums/en/wcf/thread/f570823a-8581-45ba-8b0b-ab0c7d7fcae1 So my config file looks like this <webHttpBinding> <binding name="webBinding" maxBufferSize="5242880" maxReceivedMessageSize="5242880" > <readerQuotas maxDepth="5242880" maxStringContentLength="5242880" maxArrayLength="5242880" maxBytesPerRead="5242880" maxNameTableCharCount="5242880"/> </binding> </webHttpBinding> ... ... ... <endpoint address="/" binding="webHttpBinding" bindingConfiguration="webBinding" My problem is that I can change this on the server, but there are no WCF config settings on the client as its a REST service and I'm just making a http request using the WebClient object any ideas?

• Using CakePHP with GoDaddy IIS 7 IIS7 and Microsoft URL Rewriter

  - by ricky

  Hi, I'm trying to move a CakePHP app from a Windows Apache setup to a GoDaddy shared IIS7 setup. It's been easy to migrate except for the Apache mod_rewrite part -- which obviously wouldn't work in IIS7. I basically have no url rewriting capability, which is crucial for Cake to work. GoDaddy now offers MS URL Rewriter, but they don't offer technical support for it. I haven't seen any blog post that discusses how to do this in detail. I'd really like to avoid third-party software, especially since GoDaddy provides MS URL Rewriter, which ought to be more than sufficient. The mod_rewrite directives that will allow Cake to work on GoDaddy look ridiculously easy (pasted below); can someone help me convert it to a web.config I can use with URL Rewriter? The URL Rewriter manual is really long and complicated. I'd rather not have to read the whole thing if I don't have to. Here's the contents of the apache .htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ /index.php?url=$1 [QSA,L] </IfModule> Here's a link that discusses GoDaddy's limited support for URL Rewriter: http://stackoverflow.com/questions/416727/url-rewriting-under-iis-at-godaddy Many thanks!

• stoping doGet/dopost in java servlets ?

  - by bosso

  Hello everyone, I've been playing with Java Servlets and Ajax a bit, and I've got a situation on which I would really appreciate advice. Let's say I have HTML page with a start and stop buttons, and as a result of clicking start button, overridden doGet (or doPost) method on a servlet is invoked which computes something that takes a long time to complete. (e.g. a giant loop, or even Infinite loop, doesn't matter, I'm interested in concepts here). So, I'm asking you: 1.What would be my options to kill / shut down / halt / exit doGet method whan I hit stop button on a web page? Do I use threading here, or there is simpler way? I take it that using System exit is not a very good idea, right? ;) 2.So, let's say I implement code for stopping doGet method. What would happen If I hit start on one browser(e.g.IE), and while this long computation takes place open new tab or other browser(e.g.Firefox) and open same url and hit stop? Would that stop my original computation? Is there any easy way to avoid this? I know that questions are a bit off, as I'm just starting with server-side of things. :) Any suggestions would be greatly appreciated!

• How to prove writing specifications beats code cowboys?

  - by Andrew Grant

  So I have a problem. Or rather my friend has a problem, since I would never write about my company on an internet forum. At my friend's company specification writing is, shall we say, a little underused. There's a deeply ingrained culture of writing code first and asking questions later, whether it's for a library routine or a new tool to inflict on their long suffering designers. This of course leads to situations where functionality is partially correct, incorrect, or just completely missing ("oh, just save before trying anything you may want to undo"). This usually results in a loss of productivity for those poor designers, or beta periods where bug-fixing is largely spent implementing things correctly. My friend's found his suggestions of writing (and testing against) specifications to be generally well received. Most of his colleagues have embraced the wonderful feeling of discovering false-assumptions on paper, instead of at 11pm on a Sunday in the middle of beta. Viva La Revolution! However there are a few who poo-poo anything that stands between their task and a keyboard. They laugh at the thought of actually designing anything, and write code with merry abandon. Mostly these are senior, long employed developers, reluctant to "waste time". The problem is that this second group of heretics invariably produce things (or at least something) quicker than the first. Subsequently this becomes justification along the lines of "It's pointless to write specifications for something as simple as an image resizer! Oh and those bugs where width!=height or the image uses RLE just need a few tweaks". And now the question :) Other than saying "told you so" at the end of a project, what are some good short-term ways to demonstrate how the practice of writing functional or technical specifications leads to better software in the long run? Cheers!

• Structuring projects & dependencies of large winforms applications in C#

  - by Benjol

  UPDATE: This is one of my most-visited questions, and yet I still haven't really found a satisfactory solution for my project. One idea I read in an answer to another question is to create a tool which can build solutions 'on the fly' for projects that you pick from a list. I have yet to try that though. How do you structure a very large application? Multiple smallish projects/assemblies in one big solution? A few big projects? One solution per project? And how do you manage dependencies in the case where you don't have one solution. Note: I'm looking for advice based on experience, not answers you found on Google (I can do that myself). I'm currently working on an application which has upward of 80 dlls, each in its own solution. Managing the dependencies is almost a full time job. There is a custom in-house 'source control' with added functionality for copying dependency dlls all over the place. Seems like a sub-optimum solution to me, but is there a better way? Working on a solution with 80 projects would be pretty rough in practice, I fear. (Context: winforms, not web) EDIT: (If you think this is a different question, leave me a comment) It seems to me that there are interdependencies between: Project/Solution structure for an application Folder/File structure Branch structure for source control (if you use branching) But I have great difficulty separating these out to consider them individually, if that is even possible. I have asked another related question here.

• Writing an efficient cron job script utilizing Zend_Mail_Storage_Imap.

  - by fireeyedboy

  I'm new to the IMAP protocol and Zend_Mail_Storage and I'm writing a small php script for a cron job that should regularly poll an IMAP account and check for new messages, and send an e-mail if new messages have arrived. As you can imagine, I want to only poll the IMAP account for relevant messages, and I only want to send a new e-mail if new messages have arrived since the last polled new message. So I thought of keeping track of the last message I polled with some unique identifier for a message. But I'm a bit uncertain about whether the methods I want to utilize for this do what I expect them to do though. So my questions are: Does the iterator position of Zend_Mail_Storage_Imap actually resemble some IMAP unique identifier for messages, or is it simply only and internal position of Zend_Mail_Storage_Abstract? For instance, if I tell it to seek() to message 5 (which I stored from an earlier session) will it indeed seek to the appropriate message on the IMAP server, even if for instance messages have been deleted since last session? Would keeping track of this latest polled message id in a file suffice for a cron job that, say, polls the account every 5 or 10 minutes? Or is this too naive, and should I be using a database for instance. Or is there maybe a much easier way to keep track of such state with Zend_Mail_Storage_Abstract? Also, do I need to poll every IMAP folder? Or is everything accumulated when I poll INBOX? If you could shed some light on any of these matters, I'ld appreciate it. Thanks in advance.
