  • Question about multiple 'catch'

    - by chun
    Can anyone tell me why the output of this class is 'xa'? why the other exception won't be caught? public class Tree { public static void main(String... args){ try { throw new NullPointerException(new Exception().toString()); } catch (NullPointerException e) { System.out.print("x"); } catch (RuntimeException e) { System.out.print("y"); } catch (Exception e) { System.out.print("z"); } finally{System.out.println("a");} } }

  • Is there a way to jail in Javascript, so that the DOM isn't visible

    - by TiansHUo
    I would really like to provide the user some scripting capabilities, while not giving it access to the more powerful features, like altering the DOM. That is, all input/output is tunneled thru a given interface. Like a kind of restricted javacsript. Example: If the interface is checkanswer(func) this are allowed: checkanswer( function (x,y)={ return x+y; } but these are not allowed: alert(1) document.write("hello world") eval("alert()")

  • Drawing with element array in OpenGL ES

    - by FatalMojo
    Hello! I am trying to use OpenGLES to draw a x by y matrix of squares about an arbitrary point. I have an array sideVertice[] that holds a series of vertex structs defined as such typedef struct { GLfloat x; GLfloat y; GLfloat z; } Vertex3D; and an element array defined as such GLubyte elementArray[]; my draw loop is as such glLoadIdentity(); glVertexPointer(3, GL_FLOAT, 0, cube.sideVertice); for (int i=0; i<((cube.cubeSize + 1)*(cube.cubeSize + 1)); i++) { for (int j=0; j<=3; j++) { elementArray[j] = j + i*4; glDrawElements(GL_TRIANGLE_STRIP, 4, GL_UNSIGNED_BYTE, elementArray); } } for (int i=0; i<=3; i++) elementArray[i] = i; However, the visual output is corrupted and I cannot figure out what the problem is. here is an output of the vertice held in the array: 2010-04-15 23:44:48.816 RubixGL[4203:20b] vertex[0][0] x:-26.000000 y:1.000000 2010-04-15 23:44:48.817 RubixGL[4203:20b] vertex[1][1] x:-26.000000 y:26.000000 2010-04-15 23:44:48.826 RubixGL[4203:20b] vertex[2][2] x:-1.000000 y:1.000000 2010-04-15 23:44:48.829 RubixGL[4203:20b] vertex[3][3] x:-1.000000 y:26.000000 2010-04-15 23:44:48.830 RubixGL[4203:20b] Next Face 2010-04-15 23:44:48.830 RubixGL[4203:20b] vertex[0][4] x:1.000000 y:1.000000 2010-04-15 23:44:48.832 RubixGL[4203:20b] vertex[1][5] x:1.000000 y:26.000000 2010-04-15 23:44:48.837 RubixGL[4203:20b] vertex[2][6] x:26.000000 y:1.000000 2010-04-15 23:44:48.838 RubixGL[4203:20b] vertex[3][7] x:26.000000 y:26.000000 2010-04-15 23:44:48.848 RubixGL[4203:20b] Next Face 2010-04-15 23:44:48.849 RubixGL[4203:20b] vertex[0][8] x:-26.000000 y:-26.000000 2010-04-15 23:44:48.850 RubixGL[4203:20b] vertex[1][9] x:-26.000000 y:-1.000000 2010-04-15 23:44:48.851 RubixGL[4203:20b] vertex[2][10] x:-1.000000 y:-26.000000 2010-04-15 23:44:48.852 RubixGL[4203:20b] vertex[3][11] x:-1.000000 y:-1.000000 2010-04-15 23:44:48.853 RubixGL[4203:20b] Next Face 2010-04-15 23:44:48.853 RubixGL[4203:20b] vertex[0][12] x:1.000000 y:-26.000000 2010-04-15 23:44:48.854 RubixGL[4203:20b] vertex[1][13] x:1.000000 y:-1.000000 2010-04-15 23:44:48.854 RubixGL[4203:20b] vertex[2][14] x:26.000000 y:-26.000000 2010-04-15 23:44:48.855 RubixGL[4203:20b] vertex[3][15] x:26.000000 y:-1.000000 any ideas?

  • Generate URL for File

    - by Don
    The default output of File.toURL() is file:/c:/foo/bar These don't appear to work on windows, and need to be changed to file:///c:/foo/bar Does the format file:/c:/foo/bar work correctly on Unix (I don't have a Unix machine to test on)? Is there a library that can take care of generating a URL from a File that is in the correct format for the current environment?

    Hi everyone... I'd asked a question about the splitting the a string like below: Input string: "a=aa| b=b||b | c=cc" and the output: a=aa b=b||b c=cc Kobi's answer was: var matches = "a=aa|b=b||b|c=cc".match(/(?:[^|]|\|\|)+/g) his answer was correct. But I need to use "split" method and save store the outputs in a array. so I can't use the Match Method. So please help me...

  • unfounded Secure Unsecure Messages

    - by Marty Trenouth
    I'm having significant difficulty locating the root cause for a secure/insecure message comming from IE. I've looked through the entire output and there are NO references to http: I've searched for unsource Iframes, which cause this message, and there are none and other than jquery 1.4 there isn't even the text "iframe" in the source. I'm almost at an end trying the cause for this. Does anyone have any ideas

  • Propel automatic form

    - by martin.malek
    Hi, I'm just starting with Propel and for more rapid development I'm curious if there is anything like automatic forms. Something like default administration in Django. I want to be able to output a form or to get all information I'll need. Even in the objects I didn't find all information which should be necessary to have everything for the form (name, type, length, related object, etc).

  • How do I upload a file, process it and return a result file in a single request to a REST WCF service?

    - by sharptooth
    I need to implement the following scenario in a REST service implemented in WCF: the user submits a binary file and a set of parameters the server consumes the file, does some clever work and generates a binary output file the user retrieves that binary result file and all that is done in a single operation from the client perspective. It's pretty easy in a non-REST service. How do I do that in a REST service? Where do I get started?

  • Problem with character encoding on email sent via PHP?

    - by cosgrove
    Hi everybody, Having some trouble sending properly formatted HTML e-mail from a PHP script. I am running PHP 5.3.0 and Apache 2.2.11 on Windows XP Professional. The output looks like this: Agent Summary for Support on Tuesday April 20 2010=20 Ext. Name Time Volume 137 Agent Name 01:27:25 1 138 =09 00:00:00 0 139 =09 00:00:00 0 You see the =20 and =09 in there? If you look at the HTML you also see = signs being turned into =3D. I figure this is a character encoding issue as I read the following at Wikipedia: ISO-8859-1 and Windows-1252 confusion It is very common to mislabel text data with the charset label ISO-8859-1, even though the data is really Windows-1252 encoded. In Windows-1252, codes between 0x80 and 0x9F are used for letters and punctuation, whereas they are control codes in ISO-8859-1. Many web browsers and e-mail clients will interpret ISO-8859-1 control codes as Windows-1252 characters in order to accommodate such mislabeling but it is not standard behaviour and care should be taken to avoid generating these characters in ISO-8859-1 labeled content. This looks like the problem but I don't know how to fix. My code looks like this: ob_start(); report_queue_summary($yesterday,$yesterday,$first_extension,$last_extension,$queue); $body_report = ob_get_contents(); ob_end_clean(); $body_footer = "This is an automatically generated e-mail."; $message = new Mail_mime(); $html = $body_header.$body_report.$body_footer; $message->setHTMLBody($html); $body = $message->get(); $extraheaders = array("From"=>"***redacted***","To"=>$recipient, "Subject"=>"Agent Summary for $yesterday [$queue]", "Content-type"=>"text/html; charset=iso-8859-1"); $headers = $message->headers($extraheaders); # setup e-mail; $host = "*********"; $port = "26"; $username = "*****"; $password = "*****"; # Send e-mail $smtp = Mail::factory('smtp', array ('host' => $host, 'port' => $port, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($recipient, $extraheaders, $body); if (PEAR::isError($mail)) { echo("" . $mail->getMessage() . ""); } else { echo("Message successfully sent!"); } Is the problem that I'm using output buffering?

  • Passing an array of an array of char to a function

    - by L.A. Rabida
    In my program, I may need to load a large file, but not always. So I have defined: char** largefilecontents; string fileName="large.txt"; When I need to load the file, the program calles this function: bool isitok=LoadLargeFile(fileName,largefilecontents); And the function is: bool LoadLargeFile(string &filename, char ** &lines) { if (lines) delete [] lines; ifstream largeFile; #ifdef LINUX largeFile.open(filename.c_str()); #endif #ifdef WINDOWS largeFile.open(filename.c_str(),ios::binary); #endif if (!largeFile.is_open()) return false; lines=new char *[10000]; if (!lines) return false; largeFile.clear(); largeFile.seekg(ios::beg); for (int i=0; i>-1; i++) { string line=""; getline(largeFile,line); if (largeFile.tellg()==-1) break; //when end of file is reached, tellg returns -1 lines[i]=new char[line.length()]; lines[i]=const_cast<char*>(line.c_str()); cout << lines[i] << endl; //debug output } return true; } When I view the debug output of this function, "cout << lines[i] << endl;", it is fine. But when I then check this in the main program like this, it is all messed up: for (i=0; i<10000; i++) cout << largefilecontents[i] << endl; So within the function LoadLargeFile(), the results are fine, but without LoadLargeFile(), the results are all messed up. My guess is that the char ** &lines part of the function isn't right, but I do not know what this should be. Could someone help me? Thank you in advance!

  • what the best and simplest way to find out whether a volume need defrag?

    - by r9r9r9
    I am writing a application that monitor the system's health, user should know when they need to defrag the volumes. What I am thinking is calling the "defrag.exe /A" then analyze the output result to see whether it contains "You do not need to defragment this volume." But it's slow and very bad, I fount that the "Analyze" is really quick on the MyDefrag.exe. Anyone could tell me what's the best and simplest way?
