  • Any special assertion to test if the resulting integer lies within a range

    - by barerd
    I would like to test if an instance variable lies in a range of numbers. I solved the problem by using assert_in_delta but would like to know if there is a formal assertion for this. #part of the tested class def initialize(value = 70 + rand(30)) @value = value end #test_value.rb class ValueTestCase < Test::Unit::TestCase def test_if_value_in_range assert_in_delta(85, p.value, 15) end end

  • Getting data from a ListView into an array

    - by Joe
    I have a ListView control on my form set up like this in details mode: What I would like to do, is get all the values of the data cells when the user presses the Delete booking button. So using the above example, my array would be filled with this data: values(0) = "asd" values(1) = "BS1" values(2) = "asd" values(3) = "21/04/2010" values(4) = "2" This is my code so far: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _ Me.ManageList.SelectedItems Dim item As ListViewItem Dim values(0 To 4) As String Dim i As Integer = 0 For Each item In items values(i) = item.SubItems(i).Text i = i + 1 Next End Sub But only values(0) gets filled with the first data cell of the selection (in this case "asd") and the rest of the array entries are blank. I have confirmed this with a breakpoint and checked the array entries myself. I'm REALLY lost on this, and have been trying for about an hour now. Any help would be appreciated, thanks :) Also please note that there can only be one row selection at once. Thanks.

  • NSIS - put EXE version into name of installer

    - by codeulike
    NSIS has a Name variable that you define in the script: Name "MyApp" It defines the name of the installer, that gets displayed as the window title, etc. Is there a way to pull the .NET Version number out of my main EXE and append it to the Name? So that my installer name would automatically be 'MyApp V2.2.0.0" or whatever?

  • Is it bad to explicitly compare against boolean constants e.g. if (b == false) in Java?

    - by polygenelubricants
    Is it bad to write: if (b == false) //... while (b != true) //... Is it always better to instead write: if (!b) //... while (!b) //... Presumably there is no difference in performance (or is there?), but how do you weigh the explicitness, the conciseness, the clarity, the readability, etc between the two? Note: the variable name b is just used as an example, ala foo and bar.

  • Using Cases to change background colour | Visual Studio 2008

    - by Simon
    I really need help working with cases, I'm only learning it so far, but just can't get a drop down menu to work that would change the background of a Textbox. Private Sub cbColours_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbColours.SelectedIndexChanged Select Case colours Case Is = "Red" txtSpace.BackColor = Color.Red Case Is = "Blue" txtSpace.BackColor = Color.Blue Case Is = "Green" txtSpace.BackColor = Color.Green End Select End Sub It isn't doing anything at all... In the dropdown menu, it has Red, Blue and Green one per line When the value (e.g. Green) is clicked, it will then change the Textbox to the colour selected. Many help appreciated :)

  • How to tell a method has a varargs argument using reflection?

    - by Anthony Kong
    Here is a sample code package org.example; import java.lang.reflect.Method; class TestRef { public void testA(String ... a) { for (String i : a) { System.out.println(i); } } public static void main(String[] args){ Class testRefClass = TestRef.class; for (Method m: testRefClass.getMethods()) { if (m.getName() == "testA") { System.out.println(m); } } } } The output is public void org.example.TestRef.testA(java.lang.String[]) So the signature of the method is reported to take a array of String. Is there any mean in the reflection library I can tell that the method is originally declared to take a varargs?

  • Auto-complete/suggestion popup menu in GtkTextView

    - by Tyler
    I'm trying to create a system that will allow me to respond to the current text and auto-complete/suggest what should come next. For example if the user starts to type "Batm" then the system would respond with a menu showing the full completed word "Batman". Think of an IDE like Eclipse or Visual Studio and you get the idea. I understand how to create a popup menu in Gtk+ but what I don't understand is the following: How do I grab the word that the user is currently typing from a GtkTextView (or SourceView) so that I can do a lookup and offer suggestions? How do I position the menu in such a way that it sits next to the current text item (like it would in an IDE)? If anyone could offer suggestions or even a link to a tutorial or example on how to do this correctly I would be forever grateful. As always thanks for you help! Programming language: C

  • Fixing VB6 inaccurate mathmetical results due to rounding

    - by jay
    Try running this in a .VBS file MsgBox(545.14-544.94) You get a neat little answer of 0.199999999999932! This rounding issue also occurs unfortunately in Sin(2 * pi) since VB can only ever see the (user defined) variable pi as accurate as 3.14159265358979. Is rounding it manually (and loosing accuracy) the only way to improve the result? What is the most effective way of dealing with this kind of problem?

  • A question mark within a @PathVariable in Spring MVC?

    - by sp00m
    Within the @Controller of a search engine: @RequestMapping(value = "/search/{query}", method = RequestMethod.GET) public String search(@PathVariable String query) {} If a user wants to search /search/w?rld (wich should match world, warld, whrld, etc.), the variable query equals w, because of the question mark which indicated a GET var. I tried "/search/{query:.+}", but still doesn't work. Any idea how to solve that problem?

  • What is the easiest way to loop through a folder of files in C#?

    - by badpanda
    I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

  • mysql_query -- question about results "location"

    - by Andrew Heath
    Forgive me if this is a particularly stupid question! mysql_query($query) returns a boolean, but you can also assign it to a variable $results = mysql_query($query) and then use the other mysql_ functions to extract data. Out of curiosity, how does mysq_query($query) act as both a boolean and a data container at the same time? What's happening "under the hood" during these steps? (yes, I am a n00b..., please be kind!)

  • How do I add a filter button to this pagination?

    - by ClarkSKent
    Hey, I want to add a button(link), that when clicked will filter the pagination results. I'm new to php (and programming in general) and would like to add a button like 'Automotive' and when clicked it updates the 2 mysql queries in my pagination script, seen here: As you can see, the category automotive is hardcoded in, I want it to be dynamic, so when a link is clicked it places whatever the id or class is in the category part of the query. 1: $record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='automotive'")); 2: $get = mysql_query("SELECT * FROM explore WHERE category='automotive' LIMIT $start, $per_page"); This is the entire current php pagination script that I am using: <?php //connecting to the database $error = "Could not connect to the database"; mysql_connect('localhost','root','root') or die($error); mysql_select_db('ajax_demo') or die($error); //max displayed per page $per_page = 2; //get start variable $start = $_GET['start']; //count records $record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='automotive'")); //count max pages $max_pages = $record_count / $per_page; //may come out as decimal if (!$start) $start = 0; //display data $get = mysql_query("SELECT * FROM explore WHERE category='automotive' LIMIT $start, $per_page"); while ($row = mysql_fetch_assoc($get)) { // get data $name = $row['id']; $age = $row['site_name']; echo $name." (".$age.")<br />"; } //setup prev and next variables $prev = $start - $per_page; $next = $start + $per_page; //show prev button if (!($start<=0)) echo "<a href='pagi_test.php?start=$prev'>Prev</a> "; //show page numbers //set variable for first page $i=1; for ($x=0;$x<$record_count;$x=$x+$per_page) { if ($start!=$x) echo " <a href='pagi_test.php?start=$x'>$i</a> "; else echo " <a href='pagi_test.php?start=$x'><b>$i</b></a> "; $i++; } //show next button if (!($start>=$record_count-$per_page)) echo " <a href='pagi_test.php?start=$next'>Next</a>"; ?>
