• What training book should I choose after Microsoft's Application Development Foundation (70-536)?

  - by codys-hole

  I've just finished 70-536 ("Microsoft .NET Framework - Application Development Foundation") Microsoft training book from Microsoft Press. I found it quite good. I have also done the 70-528 ("Microsoft .NET Framework 2.0 - Web-based Client Development") book. What book should I be reading next? I am job hunting, so I want to be marketable for a position as a software developer. What will make me stand out from the crowd and get the job?

• how to remove background layer of djvu file

  - by Jon

  Hello, I've downloaded some files from the Internet Archive. They come in different file formats and most of the time I use pdf. However, sometimes the scans are saves in colour instead of b/w. This makes it difficult/impossible to read on a dedicated ebook reader. In that case I downloaded the djvu files as on the PC you can select which layer (color, bw,fore,back) one would like to see. Selecting the bw gives excellent results. However, the ebook reader does not has this option. The question is, how can I remove /extract a layer from the djvu file and save only this layer. So far I've tried the following two approaches: 1) select bw in the djvu viewer on the PC and printed to postscript file. Followed by a ps2pdf conversion. This works, but generates a fairly large pdf file. Sure, I can again upload it to any2djvu but it just seems to much manual work for each file. 2) I tried the shared annotation feature and said (mode bw). This works on the PC as desired but is ignored on the ebook reader as the other layers are still present. Any help or suggestions would be greatly appreciated.

• Implementing ZBar QR Code Reader in UIView

  - by Bobster4300

  I really need help here. I'm pretty new to iOS/Objective-C so sorry if the problem resolution is obvious or if my code is terrible. Be easy on me!! :-) I'm struggling to integrate ZBarSDK for reading QR Codes into an iPad app i'm building. If I use ZBarReaderController (of which there are plenty of tutorials and guides on implementing), it works fine. However I want to make the camera come up in a UIView as opposed to the fullscreen camera. Now I have gotten as far as making the camera view (readerView) come up in the UIView (ZBarReaderView) as expected, but I get an error when it scans a code. The error does not come up until a code is scanned making me believe this is either delegate related or something else. Here's the important parts of my code: (ZBarSDK.h is imported at the PCH file) SignInViewController.h #import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> @class AVCaptureSession, AVCaptureDevice; @interface SignInViewController : UIViewController < ZBarReaderDelegate > { ZBarReaderView *readerView; UITextView *resultText; } @property (nonatomic, retain) UIImagePickerController *imgPicker; @property (strong, nonatomic) IBOutlet UITextView *resultText; @property (strong, nonatomic) IBOutlet ZBarReaderView *readerView; -(IBAction)StartScan:(id) sender; SignInViewController.m #import "SignInViewController.h" @interface SignInViewController () @end @implementation SignInViewController @synthesize resultText, readerView; -(IBAction)StartScan:(id) sender { readerView = [ZBarReaderView new]; readerView.readerDelegate = self; readerView.tracksSymbols = NO; readerView.frame = CGRectMake(30,70,230,230); readerView.torchMode = 0; readerView.device = [self frontFacingCameraIfAvailable]; ZBarImageScanner *scanner = readerView.scanner; [scanner setSymbology: ZBAR_I25 config: ZBAR_CFG_ENABLE to: 0]; [self relocateReaderPopover:[self interfaceOrientation]]; [readerView start]; [self.view addSubview: readerView]; resultText.hidden=NO; } - (void) readerControllerDidFailToRead: (ZBarReaderController*) reader withRetry: (BOOL) retry{ NSLog(@"the image picker failing to read"); } - (void) imagePickerController: (UIImagePickerController*) reader didFinishPickingMediaWithInfo: (NSDictionary*) info { NSLog(@"the image picker is calling successfully %@",info); id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults]; ZBarSymbol *symbol = nil; NSString *hiddenData; for(symbol in results) hiddenData=[NSString stringWithString:symbol.data]; NSLog(@"the symbols is the following %@",symbol.data); resultText.text=symbol.data; NSLog(@"BARCODE= %@",symbol.data); NSLog(@"SYMBOL : %@",hiddenData); resultText.text=hiddenData; } The error I get when a code is scanned: 2012-12-16 14:28:32.797 QRTestApp[7970:907] -[SignInViewController readerView:didReadSymbols:fromImage:]: unrecognized selector sent to instance 0x1e88b1c0 2012-12-16 14:28:32.799 QRTestApp[7970:907] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[SignInViewController readerView:didReadSymbols:fromImage:]: unrecognized selector sent to instance 0x1e88b1c0' I'm not too worried about what happens with the results just yet, just want to get over this error. Took me ages just to get the camera to come up in the UIView due to severe lack of tutorial or documentation on ZBarReaderView (for beginners anyway). Thanks all.

• MVC - Cocoa interface - Cocoa Design pattern book

  - by Idan

  So I started reading this book: http://www.amazon.com/Cocoa-Design-Patterns-Erik-Buck/dp/0321535022 On chapter 2 it explains about the MVC design pattern and gives and example which I need some clarification to. The simple example shows a view with the following fields: hourlyRate, WorkHours, Standarthours , salary. The example is devided into 3 parts : View - contains some text fiels and a table (the table contains a list of employees' data). Controller - comprised of NSArrayController class (contains an array of MyEmployee) Model - MyEmployee class which describes an employee. MyEmployee class has one method which return the salary according to the calculation logic, and attributes in accordance with the view UI controls. MyEmployee inherits from NSManagedObject. Few things i'm not sure of : 1. Inside the MyEmplpyee class implemenation file, the calculation method gets the class attributes using sentence like " [[self valueForKey:@"hourlyRate"] floatValue];" Howevern, inside the header there is no data member named hourlyRate or any of the view fields. I'm not quite sure how does it work, and how it gets the value from the right view field. (does it have to be the same name as the field name in the view). maybe the conncetion is made somehow using the Interface builder and was not shown in the book ? and more important: 2. how does it seperate the view from the model ? let's say ,as the book implies might happen, I decide one day to remove one of the fields in the view. as far as I understand, that means changing the way the salary method works in MyEmplpyee (cause we have one field less) , and removing one attribute from the same calss. So how is that separate the View from the Model if changing one reflect on the other ? I guess I get something wrong... Any comments ? Thanks

• Book recommendation for Silverlight

  - by Mathias Weyel

  Hi there, yet another question for recommendations for a book on Silverlight. I look for a book that covers the UI and styling and, if possible, custom drawing and graphics. Very important for me is the style of the book - it should focus on the actual programming and not on where to click in Visual Studio to get things done. Let's take a fictional example for proper usage of the DataGrid control: Bad: To use the data grid, drag it from the toolbox onto the control. You can change the background color by clicking on “Background” in the properties. To define custom columns, click on columns and edit them in the configuration window that opens. Good: To use the DataGrid, you need a reference to the blah dll and declare the namespace in the XAML like this (blah), the data model should be like blah and if you want to define how the columns look like, you need to define them like this (more blah). And if you want to do this in C# because you for whatever reason aren’t able or willing to use XAML, this would look like blah. Bonus points for coverage of topics like how to manage resources (images/fonts) and internationalization. There are quite some snippets on how to do that on the internet but somehow each of them looks like they work but are not a proper way of doing it. cheers Mathias

• Looking for a good C++/.net book

  - by Michael Minerva

  I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

• Book Recomendations: WPF/Silverlight for Business(smallish, internal) Environment

  - by Refracted Paladin

  Yes, I know there are an insane amount of Book posts here(SO) but none I believe for my specific need. If there is and I missed it I apologize. I am the only developer at a non-profit organization(~200 employees) where we are a M$ shop and 90% of the things I develop are specific to our company and are internal only. I am given a lot of latitude on how I accomplish my goals so using new technologies is in my best interest. So far I have developed all winform & asp.net applications but I am an expert by NO MEANS. I would now like to focus on XAML driven development(WPF & Silverlight) but I have no idea where to start. I am subscribed to numerous Silverlight blogs and I have went through a few good tutorials however, I would really appreciate a GOOD SOLID book in my hands going forward. I prefer learning books versus reference books and I REALLY would like one from a Business standpoint as well. Shameless, self-promoting is welcomed if you happen to be an author or reviewer for one that meets my criteria. I would, however, prefer that recomendations were based on first-hand experience(no, 'my friend as this awesome book he told me about', please). If more info is needed to provide accurate recomendations please let me know. Thanks

• Acrobat Reader ActiveX in WebBrowser stealing focus [C#]

  - by Maciej

  I'm using webBrowser.Navigate(url) control to display page. I noticed this action steals focus from current control (grid) and than I have problem to focus grid back (tired myGrid.Focus, .Select etc...) This is really annoying behaviour of browser... Does anyone knows how to prevent focus stealing by Browser or (if not) hot to force to focus control back ? EDIT: I've also tried webBrowser.DocumentCompleted event to focus back to grid EDIT 2 Good case to test this is openning PDF files webBrowser.Navigate(@"C:\TEMP\test.pdf") I believe this is ActiveX issue. On first glance it looks that this is not problem with focusing control but loosing entire Form focus... EDIT 3 I tried another approach: Form keyPress event: I thought I can capture form's keyPress and move focus from WebBrowser / AdobeReader ActiveX to my control. But surprisingly event is not fired! Looks Reader taken all control and there is no way to do anything programically until you do mouse click on (at least) form's caption Any advice (s) ?

• Printing PDFs Server-side using Acrobat Reader from ASP.NET

  - by Chris Roberts

  Hi, I have been presented with a problem which requires me to print PDF files from a server as part of an ASP.NET web service. The problem is further complicated by the fact that the PDF files I have to print can ONLY be printed using Adobe Reader (they were created using Adobe LiveCycle and have some strange protection in them). This piece of code seems to do the trick in the Visual Studio development web server, but doesn't do anything when the site's running in IIS. I'm assuming this is probably some sort of permissions issue!? I know this is a FAR from ideal thing to be trying to do, but I haven't really got much choice! Any ideas would be greatly appreciated! Dim starter As ProcessStartInfo Dim Prc As Process ' Pass File Path And Arguments starter = New ProcessStartInfo("c:\program files\...\AcroRd32.exe", "/t ""test.pdf"" ""Printer""") starter.CreateNoWindow = True starter.RedirectStandardOutput = True starter.UseShellExecute = False ' Start Adobe Process Prc = New Process() Prc.StartInfo = starter Prc.Start()

• Is there a fingerprint reader api/sdk?

  - by Nir

  I need to read the user's fingerprint from my application. What I really want is a simple SDK that works with a lot of inexpensive fingerprint readers but I can deal with something that works only with one specific model if that model is cheap and available worldwide. And it has to be royalty-free, I can pay for a development license but if I have to pay for each installation I just can't use it. What I'm doing has no relation to login or encryption, so the software included with the reader will probably be useless to me.

• JNA and ZBar(library for bar code reader)

  - by user219120

  I'm creating Java Interface with JNA for ZBar(library for bar code reader). In JNA, structures in C are needed to declare. For example:: // In C typedef struct { char* id; char* name; int age; char* sectionId } EMPLOYEE; to // In Java with JNA public static class Employee extends Structure { // com.sun.jna.Structure String id; String name; int age; String sectionId; } But in ZBar, structures have no members. For example:: // zbar-0.10/include/zbar.h // line:1009-1011 struct zbar_image_scanner_s; /** opaque image scanner object. */ typedef struct zbar_image_scanner_s zbar_image_scanner_t; That doesn't declare size or members of the structures. How can I write interfaces for these structures in JNA?

• problem parsing with XMLReader (using ReadSubTree)

  - by no9

  Hello. Im trying to build a simple XML to Controls parser in my CF application. In the code below the string im trying to parse looks like this: "<Panel><Label>Text1</Label><Label>Text2</Label></Panel>" The result i want with this code would be a Panel with two labels. But the problem is when the first Label is parsed the subreader.Read() returns false in the ParsePanelElementh method, and so it falls out of while statement. Since im new into XMLReader i must be missing something very simple. Any help would be apreciated ! peace. static class XMLParser { public static Control Parse(string aXmlString) { XmlReader reader = XmlReader.Create(new StringReader(aXmlString)); return ParseXML(reader); } public static Control ParseXML(XmlReader reader) { using (reader) { while (reader.Read()) { if (reader.NodeType == XmlNodeType.Element) { if (reader.LocalName == "Panel") { return ParsePanelElement(reader); } if (reader.LocalName == "Label") { return ParseLabelElement(reader); } } } } return null; } private static Control ParsePanelElement(XmlReader reader) { var myPanel = new Panel(); XmlReader subReader = reader.ReadSubtree(); while (subReader.Read()) { Control subControl = ParseXML(subReader); if (subControl != null) { myPanel.Controls.Add(subControl); }; } return myPanel; } private static Control ParseLabelElement(XmlReader reader) { reader.Read(); var myString = reader.Value as string; var myLabel = new Label(); myLabel.Text = myString; return myLabel; } }

• What causes "All-in-one USB Card Reader" to create 6 drives that always appear in Disk Management?

  - by tim11g

  I installed a "All-in-one USB Card Reader" to read SD cards and other media. It has caused six new drives to appear in Disk Management with six new drive letter assignments. These drives and letters are always present, even when there are no cards in the reader. When unused, they are labeled "No Media". Why does this multifunction reader cause these phantom Disks to appear and consume drive letters? Every USB port can (and does) allow removable media to be mounted and assigned a drive letter, and the drive letter assignment "disappears" when the USB drive is removed. Why are these card reader's drives and letters staying allocated permanently? Is there anything that can be done to make the slots work like a typical USB drive? (The reader is in fact connected to USB).

• iPhone simple commercial barcode reader via camera

  - by user347635

  Hey all, I've done some iPhone programming (safely midlevel) and now a requirement has come up for us to write a barcode reader that uses the iPhone camera. This is not for shopping or the general public but will be for internal use. My first thought was to simply programatically take a picture, upload it to server, and have a web service or something similar handle the heavy lifting of extracting the numbers out of the bar code. However I recently installed some apps already available on the iPhone that read bar codes, refer you to shopping sites, etc. and they seem to use the video camera to identify barcodes and extract the numbers. Does anyone know how this is being done or could point me to some open source or sample code?

• Changing order of Thunderbird email address autocomplete?

  - by Brooks Moses

  I recently did a system wipe and installed Thunderbird 3.0, and imported all of my email setup from a previous Thunderbird 2.0 installation. Almost everything is working fine, but I'm having a problem with the autocomplete in email addresses when writing messages. The relevant behavior is this: In the old 2.0 installation, the autocomplete appeared to know which email addresses I used most frequently, and so when I typed "m" in the address line, it would pick as the default selection the "m"-person who I frequently write email to. (It's possible this is an illusion and it simply picked people in the order I added them to my address book.) Thus, I have become used to typing "m"-"enter" in the address field, and getting this person. In the current 3.0 installation, however, the autocomplete order has changed. It's not the same as it was, and it's not alphabetical. The result is that I'm spending extra time looking at the email address bar, and more annoyingly, half the time the old muscle-memory kicks in and I find myself with an email that's addressed to a couple of customers rather than to my boss and coworker. Thus, two questions: How does Thunderbird determine this autocomplete order, among a set of addresses all of which are in the same address book? How can I change this ordering to be what I want? (I have tried Google-searching, and found a number of incomplete answers, nearly all of which were for version 1.0 or thereabouts, and reference settings dialog boxes that no longer exist.)

• Great Example of Community How-To Doc

  - by ultan o'broin

  Always on the lookout for examples of community doc, and here's a great one: Chet Justice (@oraclenerd) just launched an eBook version (PDF actually) of John Piwowar's (@jpiwowar) very popular multi-part E-Business Suite Installation Guide. You can obtain it using the PayPal buttons here. All in a good cause too. Creation of how-to information like this for functional or technical tasks, along with working examples about post-install steps, configurations and customizations, is what an applications community value-add is all about. Each community is different of course, an Adobe PhotoShop community might be more interested in templates. Great to see the needs of the community being met like this. If you have other examples you'd like to share, then find the comments.

• Disable plugin in Firefox (acroread)

  - by cboettig

  I installed acroread from the repositories, and it has decided it should be the default plugin in Firefox, such that when I click on a pdf, it opens in a Firefox window. Unfortunately, it does not display (at least when in dual head mode). This should be simple, but I cannot disable the plugin. Under Firefox Edit - Preferences- Applications - pdf is set to "always ask" so I don't know why it uses acroread in the first place. Under Tools - Manage Content Plugins I see acroread is selected for pdf content. I have the option in the dropdown to search for a new plugin, but not to simply download the file. Typing about:config into the Firefox toolbar gives me a list of configuration options, but does not mention plugin.disable or acroread anywhere. How do I disable the plugin? I have Firefox 11.0 on Ubuntu 11.10

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken?
