  • Automatic Data sorting/ analysis in Excel

    - by hkf
    I have data in the form of four columns. The first three columns represent time, value1, value 2. The fourth column is binary, all 0's or 1's. Is there a way to tell excel to delete time, value1 and value 2, when the corresponding binary value in column four is 0? I know this is a lot easier in C++ or matlab, but for reasons beyond my control, I must do it in excel.

  • Eclipse JFace TreeViewer level auto expansion doesn't work

    - by tamm0r
    According to the Eclipse documentation TreeViewer.setAutoExpandLevel(3) means that top-level elements are expanded, and their children, but not grandchildren. I used that in my code, but after setting the input the tree is not auto-expanded, neither on OS X nor on Linux. Expanding the tree manually (via mouse) works flawlessly. Am I missing anything?

  • How to parse HTML from JavaScript in Firefox?

    - by hmp
    What is the best way to parse (get a DOM tree of) a HTML result of XmlHttpRequest in Firefox? EDIT: I do not have the DOM tree, I want to acquire it. XmlHttpRequest's "responseXML" works only when the result is actual XML, so I have only responseText to work with. The innerHTML hack doesn't seem to work with a complete HTML document (in <html</html). - turns out it works fine.

  • how to load a file into a blob without loading into RAM first?

    - by Ace Grace
    Hi, I am using C# and I am having trouble loading large files into a binary field use byte arrays. Basically, if I load a file that is too large, I get memory problems. Is there a way to load a file into a binary field without using large amounts of ram, i.e. avoid loading the file into memory first? If it helps, I am using Advantage Database Server and this is using a winforms app not a web app. Regards

  • How to make a plugin for Finder to browse zip-archives as folders?

    - by Andrei
    What really surprises me is lack of some essential functionality in Finder, when one migrates from Windows to OS X. One of the things is a possibility to open an archive as a folder, i.e. staying in the directory tree and being able to drag and drop files from the archive to folders in the tree, sidebar etc. What would you do to enable such functionality?

  • Where are the clever uses of strict evaluation?

    - by devonrt
    It seems like there are plenty of examples of clever things being done in a lazily-evaluated language that can't be done in an environment with strict evaluation. For example infinite lists in Haskell or replacing every element in a tree with the tree's minimum value in one pass. Are there any examples of clever things being done in a strictly-evaluated language that can't easily be done in a lazily-evaluated language?

  • Simple stream read/write question in java

    - by Marius
    Hi, I'm trying to upload a file via URLConnection, but i need to read/write it as a binary file without any encoding changes. So i've tried to read byte[] array from FileInputStream, but now i have an issue. The PrintWriter object i use for outputing to the server does not allow me to do writer.write(content) (where content is of type byte[]). How can i fix this? Or is there another way to quickly copy binary data from a FileInputStream to a PrintWriter? Thank you

  • How to assign a numbering scheme to TreeNodes based on position

    - by TChristian
    I have a TreeView control in a Windows Forms application that is displaying my own subclass of TreeNode. I need to display a number along with each node's text indicating its position in the tree, like 1 for the root, 1.1 for its first child, 1.2 for its second child, etc. I'm using C# with .NET 2.0 The best that I can come up with is, after the tree is built, go to each node, recursively find the parent and append the parent's sibling number to the front of the node's text until you reach the root.
