  • Help naming a class that has a single public method called Execute()

    - by devoured elysium
    I have designed the following class that should work kind of like a method (usually the user will just run Execute()): public abstract class ??? { protected bool hasFailed = false; protected bool hasRun = false; public bool HasFailed { get { return hasFailed; } } public bool HasRun { get { return hasRun; } } private void Restart() { hasFailed = false; hasRun = false; } public bool Execute() { ExecuteImplementation(); bool returnValue = hasFailed; Restart(); return returnValue; } protected abstract void ExecuteImplementation(); } My question is: how should I name this class? Runnable? Method(sounds awkward)?

  • Help with a MySQL SELECT WHERE Clause

    - by Dr. DOT
    A column in my table contains email addresses. I have a text string that contains the a few usernames of email addresses separated by commas. I can make text sting into an array if necessary to get my SELECT WHERE clause to work correctly. Text string search argument is 'bob,sally,steve' I want to produce a WHERE clause that only returns rows where the username portion of the email address in the table matches one of the usernames in my text string search argument. Thus a row with [email protected] would not be returned but [email protected] would be. Does anyone have a WHERE clause sample that produces this result? Thanks.

Can anyone shine some light here? Thanks.

  • Need help with strange Class#getResource() issue

    - by Andreas_D
    I have some legacy code that reads a configuration file from an existing jar, like: URL url = SomeClass.class.getResource("/configuration.properties"); // some more code here using url variable InputStream in = url.openStream(); Obviously it worked before but when I execute this code, the URL is valid but I get an IOException on the third line, saying it can't find the file. The url is something like "file:jar:c:/path/to/jar/somejar.jar!configuration.properties" so it doesn't look like a classpath issue - java knows pretty well where the file can be found.. The above code is part of an ant task and it fails while the task is executed. Strange enough - I copied the code and the jar file into a separate class and it works as expected, the properties file is readable. At some point I changed the code of the ant task to URL url = SomeClass.class.getResource("/configuration.properties"); // some more code here using url variable InputStream in = SomeClass.class.getResourceAsStream("/configuration.properties"); and now it works - just until it crashes in another class where a similiar access pattern is implemented.. Why could it have worked before, why does it fail now? The only difference I see at the moment is, that the old build was done with java 1.4 while I'm trying it with Java 6 now. Workaround Today I installed Java 1.4.2_19 on the build server and made ant to use it. To my totally frustrating surprise: The problem is gone. It looks to me, that java 1.4.2 can handle URLs of this type while Java 1.6 can't (at least in my context/environment). I'm still hoping for an explanation although I'm facing the work to rewrite parts of the code to use Class#getRessourceAsStream which behaved much more stable...

  • xpath help substring expression

    - by NA
    Hi i have a document from which i am trying to extract a date. But the problem is within the node along with the date their is some text too. Something like <div class="postHeader"> Posted on July 20, 2009 9:22 PM PDT </div> From this tag i just want the date item not the Posted on text. something like ./xhtml:div[@class = 'postHeader'] is getting everything. and to be precise, the document i have is basically a nodelist of this elements for eg i will get 10 nodes of these elements with different date values but to be worse the problem is sometime inside these tags some random other tags also pops us like anchors etc. Can i write a universal expath which will just get the date out of the div tag?

  • Help translating Reflector deconstruction into compilable code

    - by code poet
    So I am Reflector-ing some framework 2.0 code and end up with the following deconstruction fixed (void* voidRef3 = ((void*) &_someMember)) { ... } This won't compile due to 'The right hand side of a fixed statement assignment may not be a cast expression' I understand that Reflector can only approximate and generally I can see a clear path but this is a bit outside my experience. Question: what is Reflector trying to describe to me? Update: Am also seeing the following fixed (IntPtr* ptrRef3 = ((IntPtr*) &this._someMember)) Update: So, as Mitch says, it is not a bitwise operator, but an addressOf operator. Question is now: fixed (IntPtr* ptrRef3 = &_someMember) fails with an 'Cannot implicitly convert type 'xxx*' to 'System.IntPtr*'. An explicit conversion exists (are you missing a cast?)' compilation error. So I seemed to be damned if I do and damned if I dont. Any ideas?

  • Help with SQL Server query

    - by Travis
    Sorry* this is what I should have put My query is creating duplicate entries for any record that has more than 1 instance (regardless of date) <asp:SqlDataSource ID="EastMonthlyHealthDS" runat="server" ConnectionString="<%$ ConnectionStrings:SNA_TRTTestConnectionString %>" SelectCommand="SELECT [SNA_Parent_Accounts].[Company], (SELECT [Monthly_HIP_Reports].[AccountHealth] from [Monthly_HIP_Reports] where ([Monthly_HIP_Reports].[YearMonth] = @ToDtRFC) AND ([SNA_Parent_Accounts].[CompID] = [Monthly_HIP_Reports].[CompID])) as [AccountHealth], [SNA_Parent_Accounts].[CompID] FROM [SNA_Parent_Accounts] LEFT OUTER JOIN [Monthly_HIP_Reports] ON [Monthly_HIP_Reports].[CompID] = [SNA_Parent_Accounts].[CompID] WHERE (([SNA_Parent_Accounts].[Classification] = 'Business') OR ([SNA_Parent_Accounts].[Classification] = 'Business Ihn')) AND ([SNA_Parent_Accounts].[Status] = 'active') AND ([SNA_Parent_Accounts].[Region] = 'east') ORDER BY [SNA_Parent_Accounts].[Company]"> <SelectParameters> <asp:ControlParameter ControlID="ddMonths" Name="ToDtRFC" PropertyName="Text" Type="String" /> </SelectParameters> </asp:SqlDataSource> Using SELECT DISTINCT appears to correct the problem, but I don't consider that a solution. There are no duplicate entries in the database. So it appears my query is superfically creating duplicates. The query should grab a list of companies that meet the criteria in the where clause, but also grab the Health status for each company in that particular [YearMonth] if present which is what the subquery is for. If an entry for that YearMonth is not present, then leave the Health status blank. but as stated earlier.. if you have an entry say for 2009-03 for CompID 2 and an entry for 2009-04 for CompID 2.. Doesn't matter what month you select it will list that company 2-3 times.

  • Android: Help with tabs view

    - by James
    So I'm trying to build a tabs view for an Android app, and for some reason I get a force close every time I try to run it on the emulator. When I run the examples, everything shows fine, so I went as far as to just about copy most of the layout from the examples(a mix of Tabs2.java and Tabs3.java), but for some reason it still wont run, any ideas? Here is my code(List1.class is a copy from the examples for testing purposes). It all compiles fine, just gets a force close the second it starts: package com.jvavrik.gcm; import android.app.TabActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.TabHost; import android.widget.TextView; public class GCM extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("g", getResources().getDrawable(R.drawable.star_big_on)) .setContent(new Intent(this, List1.class))); tabHost.addTab(tabHost.newTabSpec("tab2") .setIndicator("C") .setContent(new Intent(this, List1.class)) ); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("S") .setContent(new Intent(this, List1.class)) ); tabHost.addTab(tabHost.newTabSpec("tab4") .setIndicator("A") .setContent(new Intent(this, List1.class)) ); } }

  • need help with Java solution /newbie

    - by Racket
    Hi, I'm new to programming in general so i'm trying to be as specific as possible in this question. There's this book that i'm doing some exercises on. I managed to do more than half of what they say, but it's just one input that I have been struggling to find out. I'll write the question and thereafter my code, "Write an application that creates and prints a random phone number of the form XXX-XXX-XXXX. Include the dashes in the output. Do not let the first three digits contain an 8 or 9 (but don't be more restrictive than that), and make sure that the second set of three digits is not greater than 742. Hint: Think through the easiest way to construct the phone number. Each diigit does not have to be determined separately." OK, the highlighted sentence is what i'm looking at. Here's my code: import java.util.Random; public class PP33 { public static void main (String[] args) { Random rand = new Random(); int num1, num2, num3; num1 = rand.nextInt(900) + 100; num2 = rand.nextInt(643) + 100; num3 = rand.nextInt(9000) + 1000; System.out.println(num1+"-"+num2+"-"+num3); } } How am I suppose to do this? I'm on chapter 3 so we have not yet discussed if statements etcetera, but Aliases, String class, Packages, Import declaration, Random Class, Math Class, Formatting output (decimal- & numberFormat), Printf, Enumeration & Wrapper classes + autoboxing. So consider answer the question based only on these assumptions, please. The code doesn't have any errors. Thank you!

  • New to php and need to format a php page from html statement

  • Need to reload current_cart to get the test passed

    - by leomayleomay
    I'm testing my online store app with RSpec, here's what I'm doing: # spec/controllers/line_items_controller_spec.rb require 'spec_helper' describe LineItemsController do describe "POST 'create'" do before do @current_cart = Factory(:cart) controller.stub!(:current_cart).and_return(@current_cart) end it 'should merge two same line_items into one' do @product = Factory(:product, :name => "Tee") post 'create', {:product_id => @product.id} post 'create', {:product_id => @product.id} assert LineItem.count.should == 1 assert LineItem.first.quantity.should == 2 end end end # app/controllers/line_items_controller.rb class LineItemsController < ApplicationController def create current_cart.line_items.each do |line_item| if line_item.product_id == params[:product_id] line_item.quantity += 1 if line_item.save render :text => "success" else render :text => "failed" end return end end @line_item = current_cart.line_items.new(:product_id => params[:product_id]) if @line_item.save render :text => "success" else render :text => "failed" end end end The problem right now is it never added up two line_items having the same product into one, because the second time I entered into the line_items_controller#create, the current_cart.line_items is [], I have run current_cart.reload to get the test passed, any idea what's going wrong?

  • Wrong SQLServer syntax: need help!

    - by user512602
    Hi, this is what I want to achieve: 4 tables are involved: Players with PlayerID as PK, Competitions with CompetID as PK Results with ResultID as PK and CompetID as FK And the 4th table: PlayerResultts with ResultID + PlayerID as PK and CompetID as new column I created. Competitions, results and PlayerResults are already populated and quite large (300000 PlayerResults so far). In order to populate the PlayerResults.CompetID column, I try a Update ... (Select....) request but I'm not aware of the right syntax and it fails. Here is my feeble attempt: update PlayerResults set competid = (select distinct(r.competid) from results r, playerresults p where r.resultID = p.resultid) Error is (of course): "Msg 512, Level 16, State 1, Line 1 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , , = or when the subquery is used as an expression." Can someone put me in the right direction? TIA
