  • How do I setup Eclipse to stop on the line an exception occured?

    - by Chris Persichetti
    Hi, How can I setup Eclipse to stop at the point an exception occurred. I have an Eclipse breakpoint setup to break on an exception. In the code example below, the problem I'm having is Eclipse tries to open the Integer source code. Is there any way to just have debugger break at the point shown in my code example? If I move down the stack trace, I will get to this line, it'd be nice if there's a way to do this without the "Source not found" window coming up. This can be done in Visual Studio, so it's driving me crazy not being able to find a way to do this in Eclipse. package com.test; public class QuickTest { public static void main(String[] args) { try { test(); } catch(NumberFormatException e) { System.out.println(e.getMessage()); } } private static void test() { String str = "notAnumber"; Integer.parseInt(str);//<----I want debugger to stop here } }

    - by RC1140
    As the title says , i need to find 2 specific words in a sentence. But they can be in any order and any casing. How do i go about doing this using regex. E.g. This is a very long sentence used as a test From that sentence i need to extract the words test and long in any order i.e. test can be first or long can be first. UPDATE: What i did not mention the first part is it needs to be case insensitive as well

  • How to tell the difference between a VBscript is run from command line or by clicking it in a window?

    - by robbie
    All I want to do is differentiate between the program being run by the command line or by clicking the test.vbs file in a window. If you run the script by typing C:\testFolder\test.vbs in a command prompt, then I want the program to run differently than if you double clicked test.vbs in the testFolder. Is there some system variable that I can use to differentiate between the two scenarios? I first attempted to use WScript.Fullname to determine if the pathname ended in cscript or wscript. But that didn't work so well. Any ideas are greatly appreciated.

  • Change URL of a saved HTML file

    - by Paul Camilleri
    I am new to HTML so this question might sound a bit lame. Anyways I have a saved webpage on my desktop that when i open it in google chrome i want it to show a specific URL instead of its current location. Any ideas how i might get this to work? I tried using the history.pushState but i have no idea why it is not working. I created a simple page for now to test it: <html> <head> <script> function setURL() { history.pushState("Test","page2", "www.test.com"); } </script> </head> <body> <button type="button" onclick="setURL()">Set Url</button> </body> </html> Any help would be greatly appreciated. Thank you

  • Dereferencing confusion? What is this example here called?

    - by perf
    Considering this PHP example: class A { public function getB( ) { return new B(); } } class B { public function test( ) { echo "Hello"; } } I could use this: $a = new A( ); $b = $a->getB( ); $b->test( ); // Hello Or this: $a = new A(); $a->getB( )->test( ); // Hello Taking a closer look at the second example... What is the name of this form of expression? Does this have something to do with dereferencing? In which programming languages is this available? What other forms of this exist?

  • Why does this Bash regex match return an Exit Status of "2"?

    - by PreservedMoose
    I'm writing a Bash script that needs to scan for the existence of non-ASCII characters in filenames. I'm using the POSIX bracket regex syntax to match the non-ASCII characters, but for some reason, when I test for the match in an if/then statement, the test always returns an Exit Status of 2, and never matches my test string. Here's the code in question: FILEREQ_SOURCEFILE="Filename–WithNonAScII-Charàcters-05sec_23.98.mov" REGEX_MATCH_NONASCII="[^[:ascii:]]" if [[ $FILEREQ_SOURCEFILE =~ $REGEX_MATCH_NONASCII ]]; then echo "Exit Status: $?" echo "Matched!" else echo "Exit Status: $?" echo "No Match" fi This code always returns: Exit Status: 2 No Match I've read and re-read the bash-hackers.org explanation of how regex matching works, as well as this previous question on SO regarding matching non-ASCII characters, but for the life of me, I can't get this to work. What am I missing here?

  • Function Procedure in Java

    - by Lhea Bernardino
    Create a program that will ask the user to enter 3 numbers using for loop, then test the numbers and display it in ascending order. Sample Input: 5 2 7 Sample Output: 2 5 7 I'm stuck with the testing procedure. I don't know how to test the numbers since the variable holding those numbers is just a single variable and inside the for loop here is my sample code: import javax.swing.JOptionPane; public class ascending { public static void main(String args[]) { for(int x= 0; x<3;x++) { String Snum = JOptionPane.showInputDialog("Enter a number"); int num = Integer.parseInt(Snum); } <Here comes the program wherein I will test the 3 numbers inputted by the user and display in ascending order. I don't know where to start. :'( >

  • Why use Monte-Carlo method?

  • How to iterate over all the page breaks in an Excel 2003 worksheet via COM

    - by Martin
    I've been trying to retrieve the locations of all the page breaks on a given Excel 2003 worksheet over COM. Here's an example of the kind of thing I'm trying to do: Excel::HPageBreaksPtr pHPageBreaks = pSheet->GetHPageBreaks(); long count = pHPageBreaks->Count; for (long i=0; i < count; ++i) { Excel::HPageBreakPtr pHPageBreak = pHPageBreaks->GetItem(i+1); Excel::RangePtr pLocation = pHPageBreak->GetLocation(); printf("Page break at row %d\n", pLocation->Row); pLocation.Release(); pHPageBreak.Release(); } pHPageBreaks.Release(); I expect this to print out the row numbers of each of the horizontal page breaks in pSheet. The problem I'm having is that although count correctly indicates the number of page breaks in the worksheet, I can only ever seem to retrieve the first one. On the second run through the loop, calling pHPageBreaks->GetItem(i) throws an exception, with error number 0x8002000b, "invalid index". Attempting to use pHPageBreaks->Get_NewEnum() to get an enumerator to iterate over the collection also fails with the same error, immediately on the call to Get_NewEnum(). I've looked around for a solution, and the closest thing I've found so far is http://support.microsoft.com/kb/210663/en-us. I have tried activating various cells beyond the page breaks, including the cells just beyond the range to be printed, as well as the lower-right cell (IV65536), but it didn't help. If somebody can tell me how to get Excel to return the locations of all of the page breaks in a sheet, that would be awesome! Thank you. @Joel: Yes, I have tried displaying the user interface, and then setting ScreenUpdating to true - it produced the same results. Also, I have since tried combinations of setting pSheet->PrintArea to the entire worksheet and/or calling pSheet->ResetAllPageBreaks() before my call to get the HPageBreaks collection, which didn't help either. @Joel: I've used pSheet->UsedRange to determine the row to scroll past, and Excel does scroll past all the horizontal breaks, but I'm still having the same issue when I try to access the second one. Unfortunately, switching to Excel 2007 did not help either.

  • Example of a Good Func Spec?

    - by Alex
    Hey, I'm writing my func spec, and I was wondering if there are any good samples of a complete and well-written func spec? Like "This is a standard You're supposed to aspire to" type of spec. I know that Joel has a skeleteon of a func spec on his website, but I am looking for something more complete because I'm not of the appropriate amount of detail, formatting, etc. Thanks, Alex

  • Redis autocomplete

    - by Alfred
    Hi, How can I implement an autocomplete using redis? Say for example I have an array ["alfred","joel","jeff","addick"]. When I type a I get ["alfred", "addick"] I hope you get the point. How can I implement this using redis commands efficiently(if possible but I think it is). It would be great if I could get some simple commands I can try out via telnet to mimic this behaviour. Thanks P.S: Merry x-mas to all of you :)

    Good Morning. I've been reading Joel Spolsky's (joelonsoftware) articles and they are full of good information and tips. He's a good writer and well worth reading.

  • How can I convert XML files to one CSV file in C#?

    - by TruMan1
    I have a collection of strings that are XML content. I want to iterate thru my collection and build a CSV file to stream to the user for download (sometimes it can be hundreds in the collection). This is my loop: foreach (string response in items.Responses) { string xmlResponse = response; //BUILD CSV HERE } This is what my XML content looks like for each iteration (xmlResponse). I want to put it in a flat file including the "properties" attributes: <?xml version="1.0"?> <response> <properties id="60375c90-9dd7-400f-aafb-a8726df409a9" name="Account Request" date="Thursday, March 04, 2010 2:14:07 PM" page="http://mydomain/sitefinity/CreateAccount.aspx" ip="192.168.1.255" browser="Mozilla/5.0 (Windows;

  • good/full Boot Spirit examples using version 2 syntax

    - by bpw1621
    Almost all of the examples I've gone and looked at so far from: http://boost-spirit.com/repository/applications/show_contents.php use the old syntax. I've read and re-read the actual documentation at http://www.boost.org/doc/libs/1_42_0/libs/spirit/doc/html/index.html and the examples therein. I know Joel is starting a compiler series on the blog http://boost-spirit.com/home/ but that hasn't gotten in full swing yet. Any other resources to see worked examples using some more sophisticated/involved aspects in the context of fully working applications?

  • Why am I getting a TypeLoadException when defining a custom profile?

    - by Jedidja
    I'm writing a .NET command-line application that will migrate users from an existing database into aspnetdb. To simplify the user-specific settings, I'm using the profile class that Joel Spolsky wrote about here. It works great in the ASP.NET MVC website, but for some reason it's throwing a TypeLoadException when being used from this new application. I'm not sure why the framework is trying to load the new class from System.Web.
