  • Mono mkbundle issue

    - by Sean
    Hello, I am trying to bundle mono runtime with a C# a simple (console) program that does nothing, but 'hello world'. Got Cygwin, configured it all, though it fails: $ mkbundle -o x2 x.exe --deps -z OS is: Windows Sources: 1 Auto-dependencies: True embedding: C:\cygwin\home\Sean\x.exe compression ratio: 31.71% embedding: C:\PROGRA~2\MONO-2~1.1\lib\mono\4.0\mscorlib.dll compression ratio: 34.68% Compiling: as -o temp.o temp.s gcc -mno-cygwin -g -o x2 -Wall temp.c `pkg-config --cflags --libs mono-2|dos2unix` -lz temp.o temp.c: In function `main': temp.c:173: warning: implicit declaration of function `g_utf16_to_utf8' temp.c:173: warning: assignment makes pointer from integer without a cast temp.c:188: warning: assignment makes pointer from integer without a cast /tmp/ccu8fTcQ.o: In function `main': /home/Sean/temp.c:173: undefined reference to `_g_utf16_to_utf8' /home/Sean/temp.c:188: undefined reference to `_g_utf16_to_utf8' collect2: ld returned 1 exit status [Fail] Tried post with similar problem to mine here, but it didn't work either.

  • Why is -[UISwitch superlayer] being called?

    - by Jonathan Sterling
    I've got sort of a crazy thing going on where I have an NSProxy subclass standing in for a UISwitch. Messages sent to the proxy are forwarded to the switch. Please don't comment on whether or not this is a good design, because in context, it makes sense as an incredibly cool thing. The dealio is that when I try to add this object as an accessory view to a UITableViewCell, I get the following crash: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UISwitch superlayer]: unrecognized selector sent to instance 0x5889740' Yes, I could just set the proxy's target as the accessory view, but then I would have to keep track of the proxy so that I could release it at the right time. So, what I really want is to be able to have the proxy retained by the table cell, and released when it is removed from the view just like a normal accessory view. So, why is -[UISwitch superlayer] (a method which does not exist) being called, and how do I save the world?

  • Deploying Django at Dreamhost

    - by Imran
    I'm trying to get the Poll tutorial working at my Dreamhost account (I don't have any prior experience of deploying Django). I downloaded the script I found here (http://gabrielfalcao.com/2008/12/02/hosting-and-deploying-django-apps-on-dreamhost/) at my home directory and executed it. Now I have Python 2.5 and Django in ~/.myroot/ and my Django projects directory is ~/projects/ Here's the content of ~/projects/ directory (I copied the polls/ and and templates/polls/ directories myself). projects/ |-- admin_media -> /home/imran2140/.myroot/usr/lib/python2.5/site-packages/django/contrib/admin/media |-- dispatch.fcgi |-- polls | |-- __init__.py | |-- __init__.pyc | |-- admin.py | |-- admin.pyc | |-- models.py | |-- models.pyc | |-- polls.db | |-- urls.py | |-- urls.pyc | |-- views.py | `-- views.pyc |-- script_templates | |-- dispatch.template | `-- htaccess.template `-- templates `-- polls |-- detail.html |-- index.html `-- results.html 5 directories, 17 files Now what should I do to get the Polls app working? Update I finally got a "Hello World" Django app working with Passanger WSGI. It worked fine with both Server's default Python 2.3.5 and my installed Python 2.5.2.

  • Play video in UIWebView from NSData

    - by Papagalli
    Hello there, Does anybody know how to play a video in a UIVebView ? The video comes from the iphone library, when I pick it, I store it in core data as binary data. If i use the local url of the video it's working fine, the problem I have is that the this url refers to a folder named "tmp", and I don't know the lifetime of it. If I can get the real url of the video file it will be ok. //attachment is the core data object containing the data NSURL *url = [NSURL URLWithString:attachment.path]; [self.webView loadRequest:[NSURLRequest requestWithURL:url]]; I tried a solution that doesn't work: (i tried MIMETypes : "video/quicktime" and "video/mp4") [self.webView loadData:attachment.data MIMEType:@"video/mov" textEncodingName:nil baseURL:nil]; I think the second solution is the closest, and the problem comes from the MIMEType. Thanks by advance if anybody has a solution for this :)

  • Silverlight WCF method calls fails if WCF service is not running initially

    - by Craig
    Quite simply I have a generic Silverlight 3.0 web page that is calling a Ping method on a WCF service. I do not have the WCF service running initially when I navigate to this Silverlight page. As expected I get a communication exception when I press the Silverlight button to call the Ping method, which I catch. Now if I start the WCF service and press the Ping button I still get the communication exception. How come? The other scenario is the WCF is running when I navigate to the SL page and the Ping method call works. I turn off the WCF service, ping method fails. Turn it back on and the ping method succeeds. How come if it's not running initially the ping method fails always? I could include some sample code if you'd like but this is just a real simple Hello World example using basichttpbinding, straight out the book. Thanks, Craig

  • Date object to Calendar [Java]

    - by Samuel
    Hello World, I have a class Movie in it i have a start Date, a duration and a stop Date. Start and stop Date are Date Objects (private Date startDate ...) (It's an assignment so i cant change that) now i want to automatically calculate the stopDate by adding the duration (in min) to the startDate. By my knowledge working with the time manipulating functions of Date is deprecated hence bad practice but on the other side i see no way to convert the Date object to a calendar object in order to manipulate the time and reconvert it to a Date object. Is there a way? And if there is what would be best practice Thanks in advance Samuel

  • Interacting with google docs after logging into my google market apps - how

    - by Ali
    Hi guys I have a google apps account set up and even set up a simple hello world application from the available samples on the tutorial however I need to set it so I am able to interact with the google docs account associated with the account which has added my application. To interact with google docs I am aware that a token is requested from google upon authentication and verification of the account however that is in a situation where you code specifically for interacting with google docs - I'm talking about having access to the google docs of the account which has added my application so my application can be used to upload documents to the google docs and make references to them - basically my application is a resource management application and it needs to be able to store references to google docs.

  • C# "Enum" Serialization - Deserialization to Static Instance

    - by Walt W
    Suppose you have the following class: class Test : ISerializable { public static Test Instance1 = new Test { Value1 = "Hello" ,Value2 = 86 }; public static Test Instance2 = new Test { Value1 = "World" ,Value2 = 26 }; public String Value1 { get; private set; } public int Value2 { get; private set; } public void GetObjectData(SerializationInfo info, StreamingContext context) { //Serialize an indicator of which instance we are - Currently //I am using the FieldInfo for the static reference. } } I was wondering if it is possible / elegant to deserialize to the static instances of the class? Since the deserialization routines (I'm using BinaryFormatter, though I'd imagine others would be similar) look for a constructor with the same argument list as GetObjectData(), it seems like this can't be done directly . . Which I would presume means that the most elegant solution would be to actually use an enum, and then provide some sort of translation mechanism for turning an enum value into an instance reference. How might one go about this?

  • Why is there no IronPerl (Perl for .Net)?

    - by Renaud Bompuis
    I'm a bit disappointed that there doesn't seem to be any effort to make Perl a first-class citizen of the .Net world. I've read a few 'reasons' in the past but I don't see why they can't be overcome (different garbage collectors, hard-to-parse syntax, part of CPAN modules couldn't be ported, different communities, ...). Activestate has a Perl.Net product but it's a hack (in the good sense) around a standard interpreter and some syntactic sugar to interoperate with .Net assemblies. A few years ago they stopped they visual studio integration of Perl citing lack of interest. That was a while ago, before all the changes to .Net to make it more 'dynamic'. Am I the only one who yearns for IronPerl?

  • Simple question - XSB Prolog

    - by KP65
    Hello! I'm diving into the world of prolog headfirst but I seem to have hit shallow water! I'm looking at database manipulation in prolog with regards to this tutorial:Learn Prolog Now! It states that I can see my database by entering listing So i tried it and it should basically output everything in my .P file(facts, rules), but this is what i get, here are my sequence of commands: ? consult('D:\Prolog\testfile.P'). [testfile.P loaded] ? listing. library_directory(C:blahblahpathtoXSB) library_directory(C:blahblahXSBpath) {this is listed around 5 times)} shouldn't this command display what is in testfile.P, according to the tutorial? also, after consult testfile.P i should be ableto use assert to add more facts but it doesnt actually change anything in the testfile.P..? any ideas

  • "TypeError: draw() takes exactly 1 non-keyword argument (3 given)"

    - by Amorack
    I wrote this code to open a window with Pyglet in Python... import pyglet from pyglet import window class Window(pyglet.window.Window): def __init__(self): super(Window, self).__init__() myLabel = pyglet.text.Label("Prototype") windowText = myLabel.draw(Window, "Hello World", font_name = "Times New Roman", font_size = 36, color = (193, 205, 193, 255)) def on_draw(self): self.clear() self.label.draw() if __name__ == '__main__': window = Window() pyglet.app.run() however every time I run it I get this error: TypeError: draw() takes exactly 1 non-keyword argument (3 given) AFAIK the "(3 given)" means the problem is with the font_size or color arguments but I'm not sure. Could someone explain what's wrong and help me make this work?

Are there any ways of dealing with this error without changing real field name?

  • C# WMI, Performance Counters, & SNMP Oh My!

    - by Keith
    I have a C# windows service which listens to a MSMQ and sends each message out as an email. Since there's no UI, I'd like to offer an ability to monitor this service to see things such as # messages in queue, # emails sent (by message type perhaps), # of errors, etc. What is the best/recommended way to accomplish this? Is it WMI or performance counters? Is this data viewed using PerfMon or WMI CIM Studio? Does any approach allow one to monitor the service real-time as well as providing historical analysis? I can dig into the details myself but would appreciate some broad guidance to help demystify this subject.

  • WCF Data Services implementation strategies.

    - by Nix
    Microsoft has done a savvy job of not outlining the actual place for data services in the wonderful world of SOA/Web dev. So my question is simple, are WCF Data Services designed to be used via clients? Or has anyone ever heard of someone using them on the server side? Simple scenario a general layered architecture using BO business objects (parenthesis indicate what is being passed between layers) (XML) WCF Service - (BO)Business Logic - (BO) Dao - Entity Framework or using data services it would be where DS BO are modeled business entities to be used in data service. (XML) WCF Service -(BO) Business Logic - (BO) WCF Data Service - (DS BO)Server I can't see a use for the later, unless there are going to be a lot of cases people would be accessing your data via your Data Service Layer vs the Service layer? Thoughts anyone? I have not seen any mention of using DS from within a Service Layer....

  • How can we calculate sea distances using waypoints ?

    - by Ashish Ranpara
    Hi Friends, I have one query in which I really stuck at that. I have port database with waypoints and also routing points which I need to use in distance calculation between two ports. I have done lots of R&D to find formula which gives me distance between two points. I also need shortest route which is possible. I have reviewed online tools which allow user to calculate the distance. But I want to do the same at my own. I have reviewed Port World Distance Calculator. I reviewed the Great Circle formula to achieve that but I don't know that how we avoid landscapes in sea distance and in which direction I need to find distance for second port.

  • jquery ui tabs major style change

    - by Jonah
    I am using jquery UI tabs and I need to majorly change the styling on it. I need to rempve the background image, the borders, almost everything. I need it to look minimal, and not like it's self contained. What's the best way to do this? I need to use the default UI styling for the calendar widget however, which is on the same page. I've done a lot of research and everyone seems to point to the theme-roller. However, i do not just want to change the colors and border radii. I need to delete crap. theme-roller seems to be just change things like colors (not really useful for the real world) Is it even worth using jquery UI for my tabs?

  • Database design for very large amount of data

    - by Hossein
    Hi, I am working on a project, involving large amount of data from the delicious website.The data available is at files are "Date,UserId,Url,Tags" (for each bookmark). I normalized my database to a 3NF, and because of the nature of the queries that we wanted to use In combination I came down to 6 tables....The design looks fine, however, now a large amount of data is in the database, most of the queries needs to "join" at least 2 tables together to get the answer, sometimes 3 or 4. At first, we didn't have any performance issues, because for testing matters we haven't had added too much data in the database. No that we have a lot of data, simply joining extremely large tables does take a lot of time and for our project which has to be real-time is a disaster.I was wondering how big companies solve these issues.Looks like normalizing tables just adds complexity, but how does the big company handle large amounts of data in their databases, don't they do the normalization? thanks

  • How to paste metafile from Microsoft Word at expected size

    - by Joel
    I'm having an issue in a WPF application using the RichTextBox where content being pasted in from Microsoft Word is mangled. To work around the issue, I found that Word includes a metafile on the clipboard, and I can get the metafile from the clipboard using interop (WPF wouldn't properly import the metafile either). My problem, though, is that a metafile is scalable and so whether a user pastes a whole page of content or a small amount, the metafile claims that its Width is 4390. However, if I strip the clipboard of everything but the metafile and paste it into MSPaint, the resulting bitmap in paint has properly scaled the pasted metafile, so it seems to me that there must be some information somewhere that indicates the real size. Does anyone know how to get the proper expected size of the Metafile?
