  • Change the key being pressed with C#

    - by Benny
    Hey, I'm trying to write a program in C# that will track the pressing of certain keys (using a keyboard hook), and send different ones instead. For instance, when I press the A key it will instead send the Q key. I used http://www.codeproject.com/KB/cs/CSLLKeyboardHook.aspx this for my hooks and tried to use the SendKeys function, but I get an exception about the garbage collector destroying some object inside the hook class.

  • Open x64 'SOFTWARE' registry key in C#

    - by Lance May
    I am trying to read the 64-bit HKLM\SOFTWARE registry key from a 32-bit (C#) application. This, of course, keeps redirecting my view to HKLM\SOFTWARE\Wow6432Node. According to what I've found this is doable, but I can't seem to find a .NET example anywhere. I just need to read; not write. Anyone ran across this before?

    I anticipate using some images in my Java application. These images will be drawn onto my JPanel using g.drawImage(). The JPanel is resizable and the images should scale as the JPanel increases/decreases in size Two questions: What image format is best for this type of desired scalable image? For instance, in this application, an image of size 100x100 may be scaled into an image of size 30x30 or 10x10 or 300x300. How can I write code to do this scaling?

  • Is there a way to have three way habtm associations in rails / activerecord?

    - by txwikinger
    Often three (or more) way associations are needed for habtm associations. For instance a permission model with roles. A particular area of functionality has many users which can access many areas. The permissions on the area are setup via roles (habtm) The user/roles association is also habtm The permissions (read, write, delete, etc) are habtm towards roles. How would that be best done with rails/activerecord?

  • One-to-One relation classes

    - by SeyZ
    I want to have a class named ProjectDirectory and a class named MetaDirectory. Each project has a MetaDirectory which contains some meta data. Is it the good way to write the classes like this: class ProjectDirectory(object): def __init__(self, directory=None): self.directory = directory self.meta_directory = MetaDirectory(self) def __repr__(self): return self.directory class MetaDirectory(object): def __init__(self, project_directory=None): self.project_directory = project_directory self.directory = "%s/.meta/" % project_directory ProjectDirectory has a reference to MetaDirectory and MetaDirectory has a reference to ProjectDirectory. Is there an other solution or this solution is good ?

    I find myself doing this a lot: script/generate migration my_new_migration .. then select & copy the generated filename, then paste it into vi to actually write the migration. Is there any way to do this in one step? i.e. when the script/generate migration runs, it creates the file the automatically opens that file in an editor? (I'm working in an SSH terminal window on linux..)

  • What does <![CDATA[]]> in XML mean?

    - by mystify
    I often find this strange CDATA tag in XML files: <![CDATA[]]> I have observed that this CDATA tag always comes at the beginning, and then followed by some stuff. But sometimes it is used, sometimes it is not. I assume it is to mark that some "data" will be inserted after that. But what kind of "data"? Isn't anything I write in XML tags some sort of "data"?

  • Stored Procedure in postgresql, multiple queries w/ agreggates.

    - by fenix
    I'm trying to write a store procedure that can take some input parameters (obviously), run multiple queries against those, taking the output from those and doing calculations, and from those calculations and the original queries, outputting a formatted text string like: Number of Rows for max(Z) matching condition x and y of total rows matching x (x&y/x*100). To explain the max(Z) bit, this will be the username field, it won't matter which actual entry is picked, because the where clause will filter the results by user id, is there a saner way to do this?
