  • iphone - calculating the font size

    - by Mike
    I have to show a label with font size = 14 when the view is 480x320. Supposing I would like to do this in a way that my code will be working well for all future device's screen sizes, including iPad and others following (I am sure more will come), what is the best way to do that? I could do this proportionally, I mean, if the scale increased X, increase the fonts X, but my concern is the different aspect ratios of the devices. The iPhone aspect ratio is 1.5, but iPad's is 1.33, and other aspect ratios can come... I am not sure if this simple scale method will be enough to produce font consistency across all devices. Any suggestions? thanks for any help.

  • Calling a webservice through jquery cross domain

    - by IanCian
    hi there, i am new to jquery so please bare with me, I am trying to connect to a .asmx webservice (cross domain) by means of client-side script now actually i am having problems to use POST since it is being blocked and in firebug is giving me: OPTIONS Add(method name) 500 internal server error.

  • Inline editing of ManyToMany relation in Django

    - by vorpyg
    After working through the Django tutorial I'm now trying to build a very simple invoicing application. I want to add several Products to an Invoice, and to specify the quantity of each product in the Invoice form in the Django admin. Now I've to create a new Product object if I've got different quantites of the same Product. Right now my models look like this (Company and Customer models left out): class Product(models.Model): description = models.TextField() quantity = models.IntegerField() price = models.DecimalField(max_digits=10,decimal_places=2) tax = models.ForeignKey(Tax) class Invoice(models.Model): company = models.ForeignKey(Company) customer = models.ForeignKey(Customer) products = models.ManyToManyField(Product) invoice_no = models.IntegerField() invoice_date = models.DateField(auto_now=True) due_date = models.DateField(default=datetime.date.today() + datetime.timedelta(days=14)) I guess the quantity should be left out of the Product model, but how can I make a field for it in the Invoice model?

  • JAXB: @XmlTransient on third-party or external super class

    - by Phil
    Hi, I need some help regarding the following issue with JAXB 2.1. Sample: I've created a SpecialPerson class that extends a abstract class Person. Now I want to transform my object structure into a XML schema using JAXB. Thereby I don't want the Person XML type to appear in my XML schema to keep the schema simple. Instead I want the fields of the Person class to appear in the SpecialPerson XML type. Normally I would add the annotation @XmlTransient on class level into the Person code. The problem is that Person is a third-party class and I have no possibility to add @XmlTransient here. How can I tell JAXB that it should ignore the Person class without annotating the class. Is it possible to configure this externally somehow? Have you had the same problem before? Any ideas what the best solution for this problem would be?

  • Integrate Jasper in Rails 3

    - by AndreDurao
    I'm trying to integrate a rails 3 app with jasper following this wiki: http://wiki.rubyonrails.org/rails/pages/HowtoIntegrateJasperReports But it seems that a lot of information isn't updated so it's been very hard to make it work by myself. I've also read a topic at ruby-forum: http://www.ruby-forum.com/topic/139453 with some details explained but still couldn't make it work. My first problem is related with the render_to_string method: When the controller method runs I receive a "Template is missing" error: this is the method: def report @customers = Customer.all send_doc(render_to_string(:template => report_customers_path, :layout => false), '/pdfs', 'report.jasper', "customers", 'pdf') end Although this seems simple I'm not understanding why is this happening. Doesn't render_to_string with layout = false suposed to get me the string result of that action? I also tried :action instead of :template, but it does the same. If anybody with some expertise with this integration could help... Thanks in advance, André

  • Suppressing NSLog statements for release?

    - by fuzzygoat
    I wonder if someone could help me setup a number of NSLog statements so they print to console when executing in "Debug Mode" but don't print in "Release Mode". I understand I need to add something like DEBUG = 1 to the debug config in Xcode but I can't find where. Also how do I utilise this in my code? NSLog(@"Print Always"); if(DEBUG) NSLog(@"Print only in debug"); Is there a simple way of doing this? EDIT: I tried following this but when I entered either: OTHER_CFLAGS or GCC_PREPROCESSOR_DEFINITIONS Xcode informed me that "theres already another key named .... " gary

  • Add table of contents to RTF document

    - by Anurag Uniyal
    I am trying to generate a RTF document by hand and eventually will do it programtically. I plan to improve pyRTF so that it can generate "Table of contents", which I think it can't. I am not able to use RTF controls words (\tc, \tcf and \tcl.) to generate a TOC. http://msdn.microsoft.com/en-us/library/aa140283(office.10).aspx gives details about TOC but I couldn't find or make any example RTF which have a TOC. So is there a simple sample showing a RTF with TOC?

  • Testing C++ program with Testing classes over normally used classes

    - by paultop6
    Hi Guys, This will probably be a bot of a waffly question but ill try my best. I have a simple c++ program that i need to build testing for. I have 2 Classes i use besides the one i actually am using, these are called WebServer and BusinessLogicLayer. To test my own code i have made my own versions of these classes that feed dummy data to my class to test it functionality. I need to know a way of somehow, via a makefile for instance, how to tell the source code to use the test classes over the normally used classes. The test classes are in a different "tester" c++ file, and the tester c++ file also has its own header file. Regards Paul P.S. This is probably a badly worded question, but i dont know any better way to put my question.

  • ASP.NET MVC 2 RC2 Model Binding with NVARCHAR NOT NULL column

    - by Gary McGill
    I have a database column defined as NVARCHAR(1000) NOT NULL DEFAULT(N'') - in other words, a non-nullable text column with a default value of blank. I have a model class generated by the Linq-to-SQL Classes designer, which correctly identifies the property as not nullable. I have a TextAreaFor in my view for that property. I'm using UpdateModel in my controller to fetch the value from the form and populate the model object. If I view the web page and leave the text area blank, UpdateModel insists on setting the property to NULL instead of empty string. (Even if I set the value to blank in code prior to calling UpdateModel, it still overwrites that with NULL). Which, of course, causes the subsequent database update to fail. I could check all such properties for NULL after calling UpdateModel, but that seems ridiculous - surely there must be a better way? Please don't tell me I need a custom model binder for such a simple scenario...!

  • input onfocus problem

  • Skype Raw API (NOT COM API) send message problem

    - by Mike Trader
    In converting this CONSOLE example to a full windows dialog implementation I have run into a very "simple problem". SendMessage() (line 283) is returning zero, GetLastError reveals 0x578 - Invalid window handle. http://read.pudn.com/downloads51/sourcecode/windows/multimedia/175678/msgapitest.cpp__.htm (https://developer.skype.com/Download/Sample...example_win.zip) C++ 2005 Studio express edition instructions http://forum.skype.com/index.php?showtopic=54549 The previous call using HWND_BROADCAST works and Skype replies as expected, so I know Skype is installed and working properly. The handle I use is the wParam value from the Skype Reply message, as in the code. This is non zero, but I am not sure if there is a way to test it other than with SendMessage. The compiled app from this C++ code example (see zip download) does actually work so I am stumped. I do encode the message with UTF8, and I create an instance of the COPYDATASTRUCT in my app, populate it then call SendMessage() with the COPYDATASTRUCT pointer in lparam. Skype does not respond nor does it obey. Am I missing something obvious here?

  • Rewriting UNIX cal(1)

    - by dharmatech
    Hello, Today I was testing out SRFI 19 and wrote a simple version of the UNIX cal(1) command. Here's a version in R6RS Scheme which runs in Ikarus and Ypsilon. A few example runs. Schemers: How would you write it? Use your favorite implementation. Ruby and Python: I'm guessing that y'all have elegant date and time libraries. I'm sure you can put the Schemers to shame. ;-) Let's see what ya got. I'd also like to see Haskell and golfed versions. Is there a Stack Overflow tag for re-implementations of UNIX commands? :-) Ed

  • Having Problems Getting FreeTTS and JSAPI Working

    - by Travis
    I have a simple project idea based off of FreeTTS and the JSAPI (Java Speech API) I've downloaded and unpacked FreeTTS and run their build script. Then tried compiling my code linking in the lib directory into the class path like this: javac -cp /home/travis/Desktop/freetts-1.2/lib HelloUnleashedReader.java Which then compiles to java bytecode just fine. However when I run: java HelloUnleashedReader I get the following error: Exception in thread "main" java.lang.NoClassDefFoundError: javax/speech/EngineModeDesc Any help on this issue would be greatly appreciated as there are many sites around the net discussing problems with getting it to work but not many that discuss their solution.

  • Lucene.Net support phrases?: What is best approach to tokenize comma-delimited data (atomically) in

    - by Pete Alvin
    I have a database with a column I wish to index that has comma-delimited names, e.g., User.FullNameList = "Helen Ready, Phil Collins, Brad Paisley" I prefer to tokenize each name atomically (name as a whole searchable entity). What is the best approach for this? Did I miss a simple option to set the tokenize delimiter? Do I have to subclass or write my own class that to roll my own tokenizer? Something else? ;) Or does Lucene.net not support phrases? Or is it smart enough to handle this use case automatically? I'm sure I'm not the first person to have to do this. Googling produced no noticeable solutions.

  • Drupal CCK 3 Multigroup tables with views

    - by henrijs.seso
    Hi, Each node have CCK-3-dev multigroup with 3 fields. Can I use one of fields as table header? Values of this field are taken from Taxonomy. With a simple recipe example, where food Z and Y are 2 nodes with recipes and each node has multigroup with ingredient name (milk, fish), amount (numbers) and unit (g, kg). Is there a way to create a table like this with views, I want to use views calc to calculate total amount of ingredient needed to prepare multiple recipes: Ingredient A Ingredient B Ingredient C Food Z 200 g 700 g 0 g Food Y 500 g 1000 g 50 g I don't even need units by number, but that would be good too. Anyways, how do I get this?

  • Php character coding

    - by out_sider
    I have a file named index.php which using a mysql server gets a simple username. The mysql server is running on centOS and I have two different systems running apache serving as web servers. One is my own windows pc using a "wamp" solution which uses the mysql server refereed before and the other is the centOS server itself. I use this so I can develop in my laptop and run the final on the centOS box. The problem is this: Accessing centOS box I get (on hxxp://centos): out_sider 1lu?s 2oi Using wamp on windows I get (on hxxp://localhost): out_sider 1luís 2oi The mysql database is configured correctly seeing that both use the same and I used svn repository to move files from windows to centOS so the file is the same. Does anyone have any suggestions? Thanks in advnce

I have 2 iPhones and have tested the same app; on iPhone 2G it works fine, but on the 3G it shows the error I have written above. I tried to change the certificate and provisioning profiles, but no luck. Please let me know where I am mistaken. Thanks. Steve

  • [C++] Write connected components of a graph using Boost Graph

    - by conradlee
    I have an file that is a long list of weighted edges, in the following form node1_id node2_id weight node1_id node3_id weight and so on. So one weighted edge per line. I want to load this file into boost graph and find the connected components in the graph. Each of these connected components is a subgraph. For each of these component subgraphs, I want to write the edges in the above-described format. I want to do all this using boost graph. This problem is in principle simple, it's just I'm not sure how to implement it neatly because I don't know my way around Boost Graph. I have already spent some hours and have code that will find the connected components, but my version is surely much longer and more complicated that necessary---I'm hoping there's a boost-graph ninja out there that can show me the right, easy way.

  • Value of text box disapears - binding viewmodel to a tab (content control)

    - by Eli Perpinyal
    Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.

  • prevent the designer from calling a getter (VS 2008, WinForms)

    - by LLEA
    hi, I have a simple UserControl containing a ComboBox which is empty at first. The setter for that CB adds items to it and the getter returns the selected item. When adding this UC to a Form, the designer automatically calls the getter for the CB which is empty. The method to fill up the CB with items is called later. I can think of one or two ways to bypass this problem by "messing around" in the code. But before I start that I'd like to ask you if there is a way to stop the designer from calling the getter method. Maybe with a attribute similar to Browsable or Bindable? thx

  • insert and mofigy a record in an entity using Core Data

    - by aminfar
    I tried to find the answer of my question on the internet, but I could not. I have a simple entity in Core data that has a Value attribute (that is integer) and a Date attribute. I want to define two methods in my .m file. First method is the ADD method. It takes two arguments: an integer value (entered by user in UI) and a date (current date by default). and then insert a record into the entity based on the arguments. Second method is like an increment method. It uses the Date as a key to find a record and then increment the integer value of that record. I don't know how to write these methods. (assume that we have an Array Controller for the table in the xib file)
