    - by ripper234
    I'm working with Maven pom files, and I don't wish to source control iml files. When I open a project, IntelliJ seems to add some of the iml files it creates to the SVN source control. How can I prevent this? I have "*.iml" in an "svn:ignore" property on the repository root, but it doesn't seem to prevent IntelliJ from adding the imls.

Does any one know any kind of time frame of when Microsoft plans to add support for Smart Device Projects into Visual Studio 2010

  • Adding a MouseOverHandler to an Element?

    - by JP
    I would like to listen for the mouse over event in GWT 1.6. Since GWT 1.6 has introduced handlers and deprecated listeners I'm unsure as to how I can accomplish this with what little information exists. Note: I have an Element object.

  • Easy way to convert a string of 0's and 1's into a character? C language

    - by Nick
    I'm doing a steganography project where I read in bytes from a ppm file and add the least significant bit to an array. So once 8 bytes are read in, I would have 8 bits in my array, which should equal some character in a hidden message. Is there an easy way to convert an array of 0's and 1's into an ascii value? For example, the array: char bits[] = "0,1,1,1,0,1,0,0" would equal 't'.

  • Extending a Java Swing class in Clojure

    - by mikera
    I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods. I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances. What's the recommended way of doing this?

  • Variable Binding Class

    - by Davis
    Hi, I believe this is a tough one... I'm trying to create a collection of variable binding in a class. It is intended to look something like this: Dim x as integer, s as string Dim c as new VBindClass x = 1 s = "Hello" c.Add x, s Debug.Print c.value(x) '= 1 Debug.Print c.value(s) '= "Hello" Is there some function that allow us to retrieve a unique ID for a given variable and also get/set based on variable?
