• Java Can't Find File when Running through Eclipse

  - by derekerdmann

  When I run a Java application that should be reading from a file in Eclipse, I get a java.io.FileNotFoundException, even though the file is in the correct directory. I can compile and run the application from the command line just fine; the problem only occurs in Eclipse, with more than one project and application. Is there a setting I need to change in the run configurations or build paths to get it to find the file correctly?

• Creating a structure from bytes with ctypes and IronPython

  - by Adal

  I have the following CPython code which I now try to run in IronPython: import ctypes class BarHeader(ctypes.Structure): _fields_ = [ ("id", ctypes.c_char * 4), ("version", ctypes.c_uint32)] bar_file = open("data.bar", "rb") header_raw = bar_file.read(ctypes.sizeof(BarHeader)) header = BarHeader.from_buffer_copy(header_raw) The last line raises this exception: TypeError: expected array, got str I tried BarHeader.from_buffer_copy(bytes(header_raw)) instead of the above, but then the exception message changes to TypeError: expected array, got bytes. Any idea what I'm doing wrong?

  CGContextSetFillColorWithColor(g, [UIColor greyColor].CGColor); I'm trying to follow O'Reilly's iPhone Game Development book on page 73 Chapter 3 but I'm running into a compile error that states error: request for member 'CGColor' in something not a structure or union According to the book's errata page this is an unconfirmed errata in the book.

• Applying attribute to SVG using JS prompts 'this.textBox.style is undefined'. Why?

  - by Jack Roscoe

  Hi, I'm using the following code to draw an SVG text box, and then change its text anchor attribute to 'left' as it defaults to center and that's nasty. The text generates correctly, but when I add this second line I get the error 'this.textBox.style is undefined' in my error console. Here's my code: RenderTextBox:function() { // Render Text this.textBox = paper.text(this.x, this.y, this.htmlText); this.textBox.style.textAnchor="left"; } Any ideas?

• Load Pymacs & Ropemacs only when opening a Python file ?

  - by Mtgred

  I use Pymacs to load Ropemacs and Rope with the following lines in my .emacs as described here. (autoload 'pymacs-load "pymacs" nil t) (pymacs-load "ropemacs" "rope-") It however slowdown the startup of Emacs significantly as it takes a while to load Ropemacs. I tried the following line instead but that loads Ropemacs everytime a Python file opened... (add-hook 'python-mode-hook (lambda () (pymacs-load "ropemacs" "rope-"))) Is there a way to perform the pymacs-load when opening a Python file but only if ropemacs and rope aren't loaded yet?

  Hi All, I was writing a C program where I use 6 variables a,b,c,d,e,f a,b,c are constant values which I should pass as an argument(command line) d,e,f are going to be size of arrays(which are a part of a structure) typedef struct { blah blah } ex; ex ex0[d]; I am very confused about how to pass all these as argument. Right now I have hard coded these values,which apparently I should not be doing.

• Visual Basic 9 with Visual Studio 2010

  - by jaraics

  I'm working on a project started in VB9 (VS 2008) and now I've migrated to VS2010 (VB10) but on the production server the IDE is still VS 2008. On my developement enviroment the code compiles fine, but sometimes, - let's say - I forget an _ at the end of the line which causes the VB9 compiler to throw an error. So the question is, how could I build a project with the VS 2010 IDE but VB9 compiler? Or to force the VB10 compiler into VB9 mode?

• Is it possible to have yui editor change paragraph style without selecting text?

  - by user126861

  Is it possible to change the behavior of the yui text editor so that when you make markup changes (via the toolbar bar buttons), for example changing from a paragraph to say a heading or to a list, and you dont have any text selected it assumes you mean the current block that the cursor is in So to change a paragraph to a heading rather than selecting the whole line you just place the cursor somewhere in the paragraph and select heading from the styles drop down.

• Manually closing a port from commandline

  - by codingfreak

  Hi I want to close an open port which is in listening mode between my client and server application. Is there any manual command line option in Linux to close a port ?? NOTE: I came to know that "only the application which owns the connected socket should close it, which will happen when the application terminates." I dont understand why it is only possible by the application which opens it ... But still eager to know if there is any another way to do it ??

• GNU Smalltalk text interface hard to use

  - by None

  I built GNU Smalltalk from source on my Mac because I couldn't get it working using fink and I found VMs like Squeak hard to understand. When I run the gst command it works fine, but unlike command line interfaces such the Python and Lua ones, it is hard to use because when I use the left or right arrow keys, I want the cursor to move left or right, but instead it inserts text like "^[[D". I understand why it does this but is there any way to fix it so it is more usable?
