• Converting contents of HtmlTextWriter to a string

  - by Tony_Henrich

  I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string. I tried the reflection method mentioned here but I get a error "Unable to cast object of type 'System.Web.HttpWriter' to type 'System.IO.StringWriter". The InnerWriter type of the HtmlTextWriter is of type HttpWriter. Any ideas on how to copy the output html into a string?

• Why is there no way to do introspection in Objective C with Objects?

  - by user346741

  I have seen examples (on here especially) of calling hideous C functions and getting structures back that have to be iterated, replete with reams of underbars. Why can't I do this (pseudo to follow): Money *cost = [[Money alloc] init]; for (Property *property in [[cost class] properties]){ .. } for (Method *method in [[cost class] methods]){ .. } ?

• Ruby BigDecimal sanity check (floating point newb)

  - by Andy

  Hello, Hoping to get some feedback from someone more experienced here. I haven't dealt with the dreaded floating-point calculation before... Is my understanding correct that with Ruby BigDecimal types (even with varying precision and scale lengths) should calculate accurately or should I anticipate floating point shenanigans? All my values within a Rails application are BigDecimal type and I'm seeing some errors (they do have different decimal lengths), hoping it's just my methods and not my object types... Thanks!

• Static field in class - Is it a re-instantiated for each static method call?

  - by Jamie Dixon

  If I have a static class with a static field such as: private static myField = new myObject(); I then have a bunch of static methods that use myField. Is myField re-instantiated for each method call? My guess is that it's instantiated the first time a method is called that uses it and it remains in memory until the GC clears it up? Cheers for any pointers :-)

• IronPython overriding __setattr__ and __getattr__

  - by yodaj007

  I'm trying to implement a class in C# with a method that intercepts the Python __setattr__ and __getattr__ magic methods. I found this bug report: http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=8143 But that is from 2008, and nowhere can I find ICustomAttributes or PythonNameAttribute. I don't see anything useful in Interfaces.cs either. Can someone point me in the right direction?

• I'm tired of JButtons, how can I make a nicer GUI in java ?

  - by Jules Olléon

  So far I've only build "small" graphical applications, using swing and JComponents as I learned at school. Yet I can't bear ugly JButtons anymore. I've tried to play with the different JButton methods, like changing colors, putting icons etc. but I'm still not satisfied. How do you make a nicer GUI in java ? I'm looking for not-too-heavy alternatives (like, without big frameworks or too complicated libraries).

• Base32 Decoding

  - by trampster

  I have a base32 string which I need to convert to a byte array. And I'm having trouble finding a conversion method in the .net framework. I can find methods for base64 but not for base32. Convert.FromBase64String – something like this for base32 would be perfect. Is there such a method in the framework or do I have to roll my own?

• polymorphism and interfaces

  - by mixm

  if i have two classes x and y, both extend class w. and x implementing interface z. if i have methods doSomething(w object) and doSomething(x object), what would happen if i call doSomething(x)? edit: im implementing this on java, more specifically on android. im asking this because some classes which implement a specific interface mostly does the same thing when doSomething() is called. but there are special cases which i would like to single out.

  Lets say I have a parent class class parent { } .....

• Android: View.getTag/setTag and IllegalArgumentException

  - by Sparafusile

  Yes, I know you need a unique resource id when calling the version of these functions that requires a key, but I cannot for the life of me figure out how to create a resource id that can be used in this way. A final variable in my class wont work and neither will a hard coded value. Both threw an IllegalArgumentException. So what gives, how do you use these methods? Spara

• How do you draw a string centered vertically in Java?

  - by Paul Alexander

  I know it's a simple concept but I'm struggling with the font metrics. Centering horizontally isn't too hard but vertically seems a bit difficult. I've tried using the FontMetrics getAscent, getLeading, getXXXX methods in various combinations but no matter what I've tried the text is always off by a few pixels. Is there a way to measure the exact height of the text so that it is exactly centered.

• Updating protected attributes using update_all

  - by Jack

  Since you cannot use the normal 'update' and 'update_attribute' methods from ActiveRecord to update a protected attribute, is the following the best way to update an attribute for a single user? User.update_all("admin = true","id = 1") I'm guessing this doesn't lie in the 'best practice' category, so I'm just curious if there is a more appropriate way.

  I am interested in implementing version control for the first time. I am starting to amass custom libraries and would like to know what methods you would recommend for implementing version control on a Windows Vista OS. I also have an Ubuntu server setup.
