  • Could it be that the stack size of a Web Service is smaller than that of a Window Application?

    - by mouthpiec
    Hi, I have a program that includes a recursive function. This function when executed in a Windows Application works just fine, and when used in a Webservice, it works fine when the webservice is initiated by the VS (it assigns a random port), but this function return a stackoverflow error when the webservice is published. (note that the machine used is the same, hence it is published on my pc). Could it be that the stack size of a Web Service is smaller than that of a Window Application?

  • In C, do braces act as a stack frame?

    - by Claudiu
    If I create a variable within a new set of curly braces, is that variable popped off the stack on the closing brace, or does it hang out until the end of the function? For example: void foo() { int c[100]; { int d[200]; } //code that takes a while return; } Will d be taking up memory during the code that takes a while section?

  • unicode data with custom font doesn't work properly in ipad

    - by David Ohanyan
    I am using custom font for label and string which I am getting from unicode characters. And the font is not changing. here is the snippet of my code: NSString* str = @"\u05D0\u05D1\u05D2"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; But when I write for example : NSString* str = @"label"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; The font effect is evident. Can someone explain what's here wrong?

  • How to change font size using the Python ImageDraw Library

    - by Eldila
    I am trying to change the font size using python's ImageDraw library. You can do something like this: fontPath = "/usr/share/fonts/dejavu-lgc/DejaVuLGCSansCondensed-Bold.ttf" sans16 = ImageFont.truetype ( fontPath, 16 ) im = Image.new ( "RGB", (200,50), "#ddd" ) draw = ImageDraw.Draw ( im ) draw.text ( (10,10), "Run awayyyy!", font=sans16, fill="red" ) The problem is that I don't want to specify a font. I want to use the default font and just change the size of the font. This seems to me that it should be simple, but I can't find documentation on how to do this.

  • How to stop Cairo Dock minimizing Conky on Show Desktop?

    Every time I use Cairo Dock Show Desktop add-on Conky minimizes: I've read about the own_window_type override option on .conkyrc and it seems to work for some people but it doesn't work for me.

  • dpkg stuck downloading font files

    - by Bob Bowles
    I have been reinstalling Ubuntu 12.04. The install from USB works fine, and I could update everything OK, but when I got to re-installing my application software I hit a snag. One of the packages I tried to re-install was ttf-mscorefonts-installer. dpkg stalled during this setup, downloading a font file (it had tried to download it all night). I stopped dpkg, and attempted to re-start downloading something else, but it would not let me. The commands I typed are as follows: bob@bobStudio:~$ sudo rm /var/lib/dpkg/lock This unlocks dpkg, but if I try to do something I get the following message (eg): bob@bobStudio:~$ sudo apt-get install synaptic E: dpgk was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem So, I did just that: bob@bobStudio:~$ sudo dpkg --configure -a whereupon it started the previously failed download all over again. I went round the loop here a few times and each time after the configure command it re-started the failing download, but then I got this: bob@bobStudio:~$ sudo dpkg --configure -a Setting up update-notifier-common (0.119ubuntu8.4) ... ttf-mscorefonts-installer: downloading http://downloads.sourceforge.net/corefonts/andale32.exe Traceback (most recent call last): File "/usr/lib/update-notifier/package-data-downloader", line 234, in process_download_requests dest_file = urllib.urlretrieve(files[i])[0] File "/usr/lib/python2.7/urllib.py", line 93, in urlretrieve return _urlopener.retrieve(url, filename, reporthook, data) File "/usr/lib/python2.7/urllib.py", line 239, in retrieve fp = self.open(url, data) File "/usr/lib/python2.7/urllib.py", line 207, in open return getattr(self, name)(url) File "/usr/lib/python2.7/urllib.py", line 344, in open_http h.endheaders(data) File "/usr/lib/python2.7/httplib.py", line 954, in endheaders self._send_output(message_body) File "/usr/lib/python2.7/httplib.py", line 814, in _send_output self.send(msg) File "/usr/lib/python2.7/httplib.py", line 776, in send self.connect() File "/usr/lib/python2.7/httplib.py", line 757, in connect self.timeout, self.source_address) File "/usr/lib/python2.7/socket.py", line 553, in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM): IOError: [Errno socket error] [Errno -2] Name or service not known Setting up ttf-mscorefonts-installer (3.4ubuntu3) ... bob@bobStudio:~$ sudo apt-get update E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/ bob@bobStudio:~$ sudo rm /var/lib/dpkg/lock bob@bobStudio:~$ sudo apt-get update E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/ The good news is that, once I sorted out the file locks, this seems to have permanently aborted the setup of the font package, so at least I can do something else with dpkg. That leaves two questions: 1) How could I have broken the loop without actually crashing out of dpkg? 2) How can I set up the ttf-mscorefonts-installer package in the future? Is this download really broken, or is it 'just' a bad Internet connection?

  • Render SVG font in Adobe Illistrator or Corel Draw

    - by Viktor Burdeinyi
    Hello! I'm developing a project that produces SVG files with custom embed fonts. SVG font definition I compose as SVG font tag with help of http://www.fontsquirrel.com/fontface/generator or Batik SVG Toolkit. The resulted SVG file I try to open in following applications: Adobe Illustrator CS4 - text has default font and message noticed about font not found in system CorelDRAW X5 - text has default font and any messages don't noticed Batik SVG Browser (Squiggle) - renders text correctly The problem is all modern typographies use CorelDRAW and Abode Illustrator for print vector graphic and them render not correctly SVG. Solution As for me, I see follow solutions: Save the text with custom font as SVG path. This will work but, I can't find any solution that can convert text + TTF to SVG path data; Use other vector format, f.e. AI, EPS or CDR. This solution is difficult for me, because I use SVG paths as part of input data; Recommend our users to use Batik SVG Browser (Squiggle) or any other application which are based on Batik SVG Toolkit library. Batik SVG Toolkit requires Java runtime :( If anyone know some knowledge to open SVG embed fonts in Adobe Illustrator or CorelDRAW please share them. I would be grateful for any help. Thank you. -Viktor Burdeinyi

  • How to force an HTML JLabel in a JTree to resize when the font changes

    - by Mike
    I'm updating a Java Swing application to support the user switching the app's font from normal size to a larger size (so the user can switch between the two sizes at runtime). One problem I'm having is with a JTree that uses HTML for the tree nodes to underline the text in some nodes (the HTML is just embedded in the JLabel of each tree node). One extra thing to know about the nodes is that they're a custom component, adding a JCheckBox in front of each JLabel. The problem is that once the JTree is visible, increasing the font size causes the nodes (containing underlined text) to not resize. The HTML for those nodes seems to prevent the node from becoming wider, so when the font changes, the text becomes truncated. I think my options are to either: 1) use another approach to make the text underlined, since removing the HTML from the JLabel causes it to resize properly when the font size changes, or 2) keep the HTML formatting and somehow force the JTree/JLabels to resize when the font size is updated (possibly by firing a property change event?). The code already calls SwingUtilities.updateComponentTreeUI() on the parent JFrame when the font size gets updated. Any help would be greatly appreciated. Thanks in advance! -Mike

  • Adding a font for use in ReportLab

    - by Jimmy McCarthy
    I'm trying to add a font to the python ReportLab so that I can use it for a function. The function is using canvas.Canvas to draw a bunch of text in a PDF, nothing complicated, but I need to add a fixed width font for layout issues. When I tried to register a font using what little info I could find, that seemed to work. But when I tried to call .addFont('fontname') from my Canvas object I keep getting "PDFDocument instance has no attribute 'addFont'" Is the function just not implemented? How do I get access to fonts other than the 10 or so default ones that are listed in .getAvailableFonts? Thanks. Some example code of what I'm trying to make happen: from reportlab.pdfgen import canvas c = canvas.Canvas('label.pdf') c.addFont('TestFont') #This throws the error listed above, regardless of what argument I use (whether it refers to a font or not). c.drawString(1,1,'test data here') c.showPage() c.save() To register the font, I tried from reportlab.lib.fonts import addMapping from reportlab.pdfbase import pdfmetrics pdfmetrics.registerFont(TTFont('TestFont', 'ghettomarquee.ttf')) addMapping('TestFont', 0, 0, 'TestFont') where 'ghettomarquee.ttf' was just a random font I had lying around.

  • Can't load vector font in Nuclex Framework

    - by ProgrammerAtWork
    I've been trying to get this to work for the last 2 hours and I'm not getting what I'm doing wrong... I've added Nuclex.TrueTypeImporter to my references in my content and I've added Nuclex.Fonts & Nuclex.Graphics in my main project. I've put Arial-24-Vector.spritefont & Lindsey.spritefont in the root of my content directory. _spriteFont = Content.Load<SpriteFont>("Lindsey"); // works _testFont = Content.Load<VectorFont>("Arial-24-Vector"); // crashes I get this error on the _testFont line: File contains Microsoft.Xna.Framework.Graphics.SpriteFont but trying to load as Nuclex.Fonts.VectorFont. So I've searched around and by the looks of it it has something to do with the content importer & the content processor. For the content importer I have no new choices, so I leave it as it is, Sprite Font Description - XNA Framework for content processor and I select Vector Font - Nuclex Framework And then I try to run it. _testFont = Content.Load<VectorFont>("Arial-24-Vector"); // crashes again I get the following error Error loading "Arial-24-Vector". It does work if I load a sprite, so it's not a pathing problem. I've checked the samples, they do work, but I think they also use a different version of the XNA framework because in my version the "Content" class starts with a capital letter. I'm at a loss, so I ask here. Edit: Something super weird is going on. I've just added the following two lines to a method inside FreeTypeFontProcessor::FreeTypeFontProcessor( Microsoft::Xna::Framework::Content::Pipeline::Graphics::FontDescription ^fontDescription, FontHinter hinter, just to check if code would even get there: System::Console::WriteLine("I AM HEEREEE"); System::Console::ReadLine(); So, I compile it, put it in my project, I run it and... it works! What the hell?? This is weird because I've downloaded the binaries, they didn't work, I've compiled the binaries myself. didn't work either, but now I make a small change to the code and it works? _. So, now I remove the two lines, compile it again and it works again. Someone care to elaborate what is going on? Probably some weird caching problem!

In the previous post JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g I showed you how to create a JMS queue and its dependent objects in WebLogic Server. In this article, we will use a sample program to write a message to that queue. Please review the previous post if you have not created those objects yet, as they will be required later in this example. The previous post also includes useful background information and links to the Oracle documentation for addional research. The following post in this series will show how to read the message from the queue again. 1. Source code The following java code will be used to write a message to the JMS queue. It is based on a sample program provided with the WebLogic Server installation. The sample is not installed by default, but needs to be installed manually using the WebLogic Server Custom Installation option, together with many, other useful samples. You can either copy-paste the following code into your editor, or install all the samples. The knowledge base article in My Oracle Support: How To Install WebLogic Server and JMS Samples in WLS 10.3.x (Doc ID 1499719.1) describes how to install the samples.

How to Use This Class 2.1 From the file system on UNIX/Linux Log in to a machine with a WebLogic installation and create a directory to contain the source and code matching the package name, e.g. $HOME/examples/jms/queue. Copy the above QueueSend.java file to this directory. Set the CLASSPATH and environment to match the WebLogic server environment. Go to $MIDDLEWARE_HOME/user_projects/domains/base_domain/bin  and execute . ./setDomainEnv.sh Collect the following information required to run the script: The JNDI name of a JMS queue to use In the Weblogic server console > Services > Messaging > JMS Modules > (Module name, e.g. TestJMSModule) > (JMS queue name, e.g. TestJMSQueue)Select the queue and note its JNDI name, e.g. jms/TestJMSQueue The JNDI name of a connection factory to connect to the queue Follow the same path as above to get the connection factory for the above queue, e.g. TestConnectionFactory and its JNDI namee.g. jms/TestConnectionFactory The URL and port of the WebLogic server running the above queue Check the JMS server for the above queue and the managed server it is targeted to, for example soa_server1. Now find the port this managed server is listening on, by looking at its entry under Environment > Servers in the WLS console, e.g. 8001 The URL for the server to be given to the QueueSend program in this example will therefore be t3://host.domain:8001 e.g. t3://jbevans-lx.de.oracle.com:8001 Edit QueueSend.java and enter the above queue name and connection factory respectively under ...public final static String  JMS_FACTORY=" jms/TestConnectionFactory "; ... public final static String QUEUE=" jms/TestJMSQueue "; ... Compile QueueSend.java using javac QueueSend.java Go to the source’s top-level directory and execute it using java examples.jms.queue.QueueSend t3://jbevans-lx.de.oracle.com:8001 This will prompt for a text input or “quit” to end. In the WLS console, go to the queue and select Monitoring to confirm that a new message was written to the queue. 2.2 From JDeveloper Create a new application in JDeveloper, called, for example JMSTests. When prompted for a project name, enter QueueSend and select Java as the technology Default Package = examples.jms.queue (but you can enter anything here as you will overwrite it in the code later). Leave the other values at their defaults. Press Finish Create a new Java class called QueueSend and use the default values This will create a file called QueueSend.java. Open QueueSend.java, if it is not already open and replace all its contents with the QueueSend java code listed above Some lines might have warnings due to unfound objects. These are due to missing libraries in the JDeveloper project. Add the following libraries to the JDeveloper project: right-click the QueueSend  project in the navigation menu and select Libraries and Classpath , then Add JAR/Directory  Go to the folder containing the JDeveloper installation and find/choose the file javax.jms_1.1.1.jar , e.g. at D:\oracle\jdev11116\modules\javax.jms_1.1.1.jar Do the same for the weblogic.jar file located, for example in D:\oracle\jdev11116\wlserver_10.3\server\lib\weblogic.jar Now you should be able to compile the project, for example by selecting the Make or Rebuild icons   If you try to execute the project, you will get a usage message, as it requires a parameter pointing to the WLS installation containing the JMS queue, for example t3://jbevans-lx.de.oracle.com:8001 . You can automatically pass this parameter to the program from JDeveloper by editing the project’s Run/Debug/Profile. Select the project properties, select Run/Debug/Profile and edit the Default run configuration and add the connection parameter to the Program Arguments field If you execute it again, you will see that it has passed the parameter to the start command If you get a ClassNotFoundException for the class weblogic.jndi.WLInitialContextFactory , then check that the weblogic.jar file was correctly added to the project in one of the earlier steps above. Set the values of JMS_FACTORY and QUEUE the same way as described above in the description of how to use this from a Linux file system, i.e. ...public final static String  JMS_FACTORY=" jms/TestConnectionFactory "; ... public final static String QUEUE=" jms/TestJMSQueue "; ... You need to make one more change to the project. If you execute it now, it will prompt for the payload for the JMS message, but you won’t be able to enter it by default in JDeveloper. You need to enable program input for the project first. Select the project’s properties, then Tool Settings, then check the Allow Program Input checkbox at the bottom and Save. Now when you execute the project, you will get a text entry field at the bottom into which you can enter the payload. You can enter multiple messages until you enter “quit”, which will cause the program to stop. The following screen shot shows the TestJMSQueue’s Monitoring page, after a message was sent to the queue: This concludes the sample. In the following post I will show you how to read the message from the queue again.

  • Android: bug in launchMode="singleTask"? -> activity stack not preserved

    - by Stefan Klumpp
    My main activity A has as set android:launchMode="singleTask" in the manifest. Now, whenever I start another activity from there, e.g. B and press the HOME BUTTON on the phone to return to the home screen and then again go back to my app, either via pressing the app's button or pressing the HOME BUTTONlong to show my most recent apps it doesn't preserve my activity stack and returns straight to A instead of the expected activity B. Here the two behaviors: Expected: A > B > HOME > B Actual: A > B > HOME > A (bad!) Is there a setting I'm missing or is this a bug? If the latter, is there a workaround for this until the bug is fixed? FYI: This question has already been discussed here. However, it doesn't seem that there is any real solution to this, yet.

  • why gcc 4.x default reserve 8 bytes for stack on linux when calling a method?

    - by nikcname
    as a beginner of asm, I am checking gcc -S generated asm code to learn. why gcc 4.x default reserve 8 bytes for stack when calling a method? func18 is the empty function with no return no param no local var defined. I can't figure out why 8 bytes is reserved here (neither any forum/site mention for the reason, ppl seems take it for granted) is it for the %ebp just push? or return type?! many thx! .globl _func18 _func18: pushl %ebp movl %esp, %ebp subl $8, %esp .text
