• Table and Image in a single page of QTextDocument in Qt4

  - by liaK

  Hi, I want to display a table and a image side by side. i.e Left side the image and right side the table. I want this because the image is the reference image for the data present in the table. I want that output in pdf. So I am using QTextDocument, QTextCursor and QPrinter to get the output in pdf. So how it is possible to display the image and table in QtextDocument i.e within a single page of the pdf? I am using Qt 4.5.3 and Windows Xp. Any pointers regarding this are welcome.

• Using TTSearchBar with TTThumbsViewController

  - by scompt.com

  I would like to layout a TTSearchBar above above a TTThumbsViewController. My current (failing) attempt involves my own SearchViewController that inherits from TTViewController and contains a reference to a TTThumbsViewController and TTSearchBar. In the loadView method, I instantiate both TTThumbsViewController and TTSearchBar and add them (actually, ..the view property of the TTTVC) as subviews. When the SearchViewController is pushed, neither the TTThumbsViewController nor the TTSearchBar are displayed. Am I going about this wrong? Is there a better way to add search to the TTThumbsViewController?

• Using nodereference + views to create combined view

  - by Ian Silber

  I'm trying to set up a relational View but not sure how to do it. Here's an example of what I'm going for using the node types Artist and Song. Artist Song Length Bob Dylan Like a Rolling Stone 2:00 Bruce Springsteen Atlantic City 4:00 Burce Springsteen Born to Run 5:24 Van Morrison Domino 3:22 Van Morrison Brown Eyed Girl 4:30 Assuming I have an Artist node type that has a node reference to Song (set to unlimited) and a Song data type with an additional field for length, how would I go about configuring the view to output this view? Thanks! Ian

• Is it better to comment out unneeded code or delete it?

  - by Matt Connolly

  For web applications under maintenance, assuming you have source control, when you need to remove part of the UI and the associated code, do you delete the code and check in, or do you comment out the old code? Arguments in favor of deleting: cleaner code, can still see deleted code in source control history, no worrying about refactoring code that might be uncommented some day. Arguments in favor of commenting: sometimes you need to add the feature back in and the developer adding it back in may not know to check source control history, sometimes the code represents unique functionality that can be a handy reference, seeing it all in one place can help provide clues to deciphering the active code.

• How can match end-of-line multiple times in a regex without interpolation?

  - by harschware

  Hi, if I have a input with new lines in it like: [INFO] xyz [INFO] How can I pull out the xyz part? I tried a pattern like /^\[INFO\]$(.*?)$\[INFO\]/ms, but perl gives me: Use of uninitialized value $\ in regexp compilation at scripts\t.pl line 6. I've been trying things to get interpolation to stop like using qr// but alas, no love. EDIT: The key is that the end-of-line anchor is a dollar sign but at times it may be necessary to intersperse the end-of-line anchor through the pattern. If the pattern is interpolating then you might get problems such as uninitialized $\. For instance an acceptable solution here is /^\[INFO\]\s*^(.*?)\s*^\[INFO\]/ms but that does not solve the crux of the first problem. I've changed the anchors to be ^ so there is no interpolation going on, and with this input I'm free to do that. But what about when I really do want to reference EOL with $ in my pattern? How do I get the regex to compile?

• PropertyInfo SetValue and nulls

  - by Nelson

  If I have something like: object value = null; Foo foo = new Foo(); PropertyInfo property = Foo.GetProperties().Single(p => p.Name == "IntProperty"); property.SetValue(foo, value, null); Then foo.IntProperty gets set to 0, even though value = null. It appears it's doing somemething like IntProperty = default(typeof(int)). I would like to throw an InvalidCastException if IntProperty is not a "nullable" type (Nullable< or reference). I'm using Reflection, so I don't know the type ahead of time. How would I go about doing this?

• Dynamic classloading fails on runtime

  - by Henrik Paul

  I have the following snippet of java code: final Class<?> junitCoreClass = AccessController.doPrivileged( new PrivilegedAction<URLClassLoader>() { @Override public URLClassLoader run() { return new URLClassLoader(new URL[] { junitJarUrl }); } }).loadClass("org.junit.runner.JUnitCore"); System.out.println(junitCoreClass.getName()); final JUnitCore junitCore = (JUnitCore) junitCoreClass.newInstance(); This compiles fine. But when I try to run it, something weird happens; a java.lang.NoClassDefFoundError is thrown on that last line, referring to the class just loaded. The weird part is, the println prints the exact class name. I checked that if I keep the reference as an Object and manipulate it only through reflection, everything's fine, so the offending piece of code must be the explicit cast. Can someone explain to me why this happens, and also tell me how I can achieve what I'm trying to do?

• Why should I use a container div in HTML?

  - by lara.robertson

  I am currently learning html/css, and have noticed a common technique is to place a generic container div in the root of the body tag: <html> <head> ... </head> <body> <div id="container"> ... </div> </body> </html> Is there a valid reason for doing this? Why can't the css just reference the body tag?

• Why is generated XAML spitting out namespaces that are not asked for?

  - by Matt Holmes

  I have a very simple XAML form, that has one namespace definition. For some reason, when Visual Studio processes that XAML file in to it's component .g.cs, it's sticking a bunch of namespace definitions at the top that I have not asked for in the XAML, or the code behind, and they are namespaces that no longer exist in my project. Thus the project is failing to compile. Why is Visual Studio sticking arbitrary namespace 'using' statements in my generated XAML .g.cs files? It's caused my entire project to break. Not one time did this .xaml file ever reference the namespaces in question, so it's doubly annoying.

• Unable to remove package from Delphi 2005

  - by Robo

  I needed to reinstall a package, DrRX.bpl. I removed it from the package list, and trying to install a newer version of the same package. I've replaced the old component's dir with the new one. When I open the new DrRX.bpl and click install, I get the error "Package C:\Program Files\Borland\BDS\3.0\components\rx work\output\DrRx.bpl cannot be installed because another package with the same basename is already loaded (DrRx.bpl)" I cannot find any reference to DrRX in my package list, DrRX does not appear in the Tool Palette. How do I locate where Delphi thinks this is installed, and remove it, so I can reinstall the package?

• Property in a Windows Forms form class only accessable after Load event

  - by Spooky2010

  I'm instantiating and calling Form B from Form A. FormB has some custom properties, to allow me to pass it things like sqlAdaptors and dataset instances. When i instantiate and show Form B from Form A as a dialog form with a Using statement, it all works fine, but i find the properties i pass are not available in Form B until after the form_load event has fired. I was under the impression the properties when passed to a instantiated class should be available from a constructor, but this is not the case. If it try to access the properties before the form load event i get a null reference exception. Is this correct behavior ?

• How to determine what invokes User Access Control restrictions?

  - by MX4399

  In a Delphi app intended to build an internet software update service for my software, the Windows 7 UAC system requests authorization from the user to run the exe.The following possible contentious/risk areas exist in the code: A named pipe server is created for communications TCP is used for FTP and HTTP SHGetSpecialFolderPath api call is used Before these items where added UAC did not activate, removing each in turn including all unit reference and then ending with the bare bones exe still causes the UAC event - so its not possible say what is causing it. On top of this Delphi 2007 now requires being launced as an administrator to launcg a debugging process for the app. Question 1 : How can I see what is causing this besides starting from scratch in a new exe - IOW is there a log somewhere I can check Question 2 : Will using a signed exe using authenticode still cause the UAC alert to show

• Qt compilation and stylesheet

  - by Yosko

  Each time I compile my Qt project after modifying my qss stylesheet file, the modifications aren't taken into account, unless I rebuild everything. Any idea on a workaround for this, so that I don't have to wait 5 minutes each time I change my qss ? Notes: I use Qt 4.8, and my stylsheet is declared in a resource file (qrc). EDIT: As suggested by Luca Carlon, when a qss is reference in the project through a .qrc file, the changes in the qss don't affect the qrc, and the compiler ignores it. To avoid that, I added a Custom Build Step to my project: before the qmake step! calls a .bat file without any argument the .bat contains the real command copy /b files.qrc +,,

• python class attribute

  - by chnet

  Hi, i have a question about class attribute in python. class base : def __init__ (self): pass derived_val = 1 t1 = base() t2 = base () t2.derived_val +=1 t2.__class__.derived_val +=2 print t2.derived_val # its value is 2 print t2.__class__.derived_val # its value is 3 The results are different. I also use id() function to find t2.derived_val and t2.class.derived_val have different memory address. My problem is derived_val is class attribute. Why it is different in above example? Is it because the instance of class copy its own derived_val beside the class attribute?

• WPF - copy/paste selection with custom font family

  - by summergoat

  I have a custom font family embedded in my WPF application which I can reference by specifying a base URI and font family name. new FontFamily(new Uri("pack://application:,,,/Fonts/"), "./#My Custom Font Family"); However, when I copy a selection which uses this font the xaml on the clipboard resembles the following <Run Text="Foo" FontFamily="./#My Custom Font Family" /> When I paste into the same RichTextBox I lose the font as it falls back to the system default because - When a FontFamily is specified as an attribute in markup, the base URI value is always implied—its value is the URI of the XAML page. http://msdn.microsoft.com/en-us/library/system.windows.media.fontfamily.aspx and my xaml page is not located in the same directory as the custom font family. Any ideas for a workaround?

  Hi Everyone, I have a kase model which I am using a simple search form in. The problem I am having is some kases are linked to companies through a company model, and people through a people model.

OR transport LIKE ? OR goods LIKE ? OR comments LIKE ? OR invoicenumber LIKE ? OR netamount LIKE ? OR clientref LIKE ? OR kase_status LIKE ? OR lyingatlocationaddresscity LIKE ?', search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition]) end What I am trying to work out, is what condition can I add to allow a search by Company or Person to show the cases they are linked to. @kase.company.companyname and company.companyname don't work :( Is this possible? Thanks, Danny

• Condensing multiple else if statements, referencing them from a table?

  - by Haskella

  Hi I'm about to type some 500 else if statements into my code (PHP) which have the exact same coding each: if (color=White); rgb = 255-255-255; print rgb; else if (color=Black); rgb = 0-0-0; print rgb; else if (color=Red); rgb = 255-0-0; print rgb; else if (color=Blue); rgb = 0-0-255; print rgb; [the list keeps going] I also (luckily) have a table that displays the color in the first column and rgb value in the next column for 500 of them... how do I use this to save time typing all those else if statements? Some how I have to reference the table file (made in excel, I'm guessing I'll have to save it as .csv?)

• Best way to get an Application Context into a static method in Android

  - by Slapout

  I'm working on an Android application that has several Activities. In it I have a class with several static methods. I would like to be able to call these methods from the different Activities. I'm using the static methods to load data from an xml file via a XmlResourceParser. To create a XmlResourceParser requires a call on the Application Context. So my question is, what is the best way to get a reference to the Application Context into the static methods? Have each Activity get it and pass it in? Store it somehow in a global variable?

• In an ASP.NET MVC site, where would the JQuery code go?

  - by Maxim Z.

  I'm just getting started with ASP.NET MVC. I'm going to be using JQuery on the website I'm making, but I'm not really sure about one thing: where would JQuery code be placed? This concerns two things: Where do I import the JQuery JavaScript file? (I've been thinking that the Master page would be a good place to do this; am I right, or do I have to import it in each view?) Should all my JQuery code be referenced from the Master page (i.e., I store my code that uses JQuery in a separate .js file and reference it in a <script> tag)? Thanks in advance.

• VB.net Need Text Box to Only Accept Numbers

  - by Rico Jackson

  I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems. Thanks again to anyone who can help. If TxtBox.Text > 10 Then MessageBox.Show("Please Enter a Number from 1 to 10") TxtBox.Focus() ElseIf TxtBox.Text < 10 Then MessageBox.Show("Thank You, your rating was " & TxtBox.Text) Total = Total + 1 ElseIf IsNumeric(TxtBox.Text) Then MessageBox.Show("Thank you, your rating was " & ValueTxtBox.Text) End If ValueTxtBox.Clear() ValueTxtBox.Focus()

• How much do politics/office intrigue interfere with your day to day tasks at work?

  - by Michael Dorgan

  I'm currently blessed to be employed at a location where politics are pretty much non-existant and management overhead is nearly nil. As I've only worked at this one location for my entire, lengthy career, I have very little frame of reference outside of an occasional Dilbert comic or offhand comment from others about just how bad office politics and management interference get in the way of getting your code done elsewhere. While I'm not actively looking for a new job, this one point has made me quite reluctant to even look seriously elsewhere. My question is, just how much are politics a way of life in larger companies - in or out of the game industry and how much does it affect your day to day satisfaction?
