  • Find a variable with a given value in VS2008

    - by Aaron
    I have an instance variable with several members, many of which have their own members and so on. Using the debugger and watch variables, I found a string variable with a specific value that I need by diving into this variable's members. However, after spending some time on other things and coming back to this, I am now unable to find where this value is located. When I have my application paused, is there a way to search the values of variables in the current context for a given value? To clarify, if I have the given structure: myVariable | |--aMember1 | |--subMember = "A value" | |--aMember2 |--subMember = "Another value" Is there a way (possibly using the watch list in VS debugger) to search myVariable for any member or submember with the value "A value", returning to me the path myVariable->aMember->subMember?

  • Drupal: How to Render Results of Form on Same Page as Form

    - by Aaron
    How would I print the results of a form submission on the same page as the form itself? Relevant hook_menu: $items['admin/content/ncbi_subsites/paths'] = array( 'title' => 'Paths', 'description' => 'Paths for a particular subsite', 'page callback' => 'ncbi_subsites_show_path_page', 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_LOCAL_TASK, ); page callback: function ncbi_subsites_show_path_page() { $f = drupal_get_form('_ncbi_subsites_show_paths_form'); return $f; } Form building function: function _ncbi_subsites_show_paths_form() { // bunch of code here $form['subsite'] = array( '#title' => t('Subsites'), '#type' => 'select', '#description' => 'Choose a subsite to get its paths', '#default_value' => 'Choose a subsite', '#options'=> $tmp, ); $form['showthem'] = array( '#type' => 'submit', '#value' => 'Show paths', '#submit' => array( 'ncbi_subsites_show_paths_submit'), ); return $form; } Submit function (skipped validate function for brevity) function ncbi_subsites_show_paths_submit( &$form, &$form_state ) { //dpm ( $form_state ); $subsite_name = $form_state['values']['subsite']; $subsite = new Subsite( $subsite_name ); //y own class that I use internally in this module $paths = $subsite->normalized_paths; // build list $list = theme_item_list( $paths ); } If I print that $list variable, it is exactly what I want, but I am not sure how to get it into the page with the original form page built from 'ncbi_subsites_show_path_page'. Any help is much appreciated!

  • How can I build a voting system to support multiple types of objects to vote on?

    - by Kyle Hayes
    I'm really looking for something very similar to the way SO is setup where a few different kinds of things can be voted on (questions AND answers). What kind of DB schema, generally, could I use to support voting on many different kinds of objects? Would I have a single Vote table that would have references to other objects in the database? Or do I have to have or should have a separate vote table for each of the objects I would like to vote on.

  • WCF: get generic type object (e.g. MyObject<T>) from remote machine

    - by Aaron
    I have two applications that are communicating through WCF. On the server the following object exists: public class MyObject<T> { ... public Entry<T> GetValue() } Where Entry<T> is another object with T Data as a public property. T could be any number of types (string, double, etc) On the client I have ClientObject<T> that needs to get the value of Data from the server (same type). Since I'm using WCF, I have to define my ServiceContract as an interface, and I can't have ClientObject<T> call Entry<T> GetMyObjectValue (string Name) which calls GetValue on the correct MyObject<T> because my interface isn't aware of the type information. I've tried implementing separate GetValue functions (GetMyObjectValueDouble, GetMyObjectValueString) in the interface and then have ClientObject determine the correct one to call. However, Entry<T> val = (Entry<T>)GetMyObjectValueDouble(...); doesn't work because it's not sure about the type information. How can I go about getting a generic object over WCF with the correct type information? Let me know if there are other details I can provide. Thanks!

  • Extracting a number from a 1-word string

    - by Kyle
    In this program I am trying to make, I have an expression (such as "I=23mm", or "H=4V") and I am trying to extract the 23 (or the 4) out of it, so that I can turn it into an integer. The problem I keep running into is that since the expression I am trying to take the numbers out of is 1 word, I cannot use split() or anything. One example I saw but wouldnt work was - I="I=2.7A" [int(s) for s in I.split() if s.isdigit()] This wouldnt work because it only takes the numbers are are delimited by spaces. If there was a number in the word int078vert, it wouldnt extract it. Also, mine doesnt have spaces to delimit. I tried one that looked like this, re.findall("\d+.\d+", "Amps= 1.4 I") but it didnt work either, because the number that is being passed is not always 2 digits. It could be something like 5, or something like 13.6. What code do I need to write so that if I pass a string, such as I="I=2.4A" or I="A=3V" So that I can extract only the number out of this string? (and do operations on it)? There are no spaces or other constant chars that I can delimit by.

  • What is the best way to include other scripts?

    - by Aaron H.
    The way you would normally include a script in bash is source. For example: main #!/bin/bash source incl.bash echo "The main script" incl.bash echo "The included script" The output of executing ./main: The included script The main script Now, if you attempt to execute that shell script from another location, it can't find the include unless it's in your PATH. What's a good way to ensure that your script can find the included script, especially if for instance, the script needs to be portable?

  • Exposing console apps to the web with Ruby

    - by Aaron
    I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

  • Programmatically Update UITableView in Response to Button Press

    - by Kyle Begeman
    I have a completely custom view that holds a UITableView and a Custom Tab Bar (basically a UIView that contains 6 UIButtons). I am loading data from a plist file, and then I am sorting the data into multiple arrays based on categories (an array for misc items, and array for mail items, etc.) Each button in the tab bar represents a category, and when I press the button I call the custom function "miscSelected" and so on. How can I have the table view completely reload and then display the tableview based on the array selected (select the misc category and the tableview clears itself and loads the misc array data, same for any other category)? The method I have experimented with is created and NSString named "selection" and then in each button function I set selected to equal whatever section I am selecting. In my cellForRoxAtIndexPath method I have this: if ([self.selection isEqualToString:@"All Items"]) { NSArray *mainDataArray = [NSArray arrayWithContentsOfFile:self.plistFile]; NSSortDescriptor *brandDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [NSArray arrayWithObject:brandDescriptor]; self.sortedData = [mainDataArray sortedArrayUsingDescriptors:sortDescriptors]; } else if ([self.selection isEqualToString:@"Misc Items"]){ self.sortedData = [NSArray arrayWithContentsOfFile:self.plistFile]; } cell.itemTitle.text = [[self.sortedData objectAtIndex:indexPath.row] objectForKey:@"name"]; For the sake of example and testing I am simply displaying the same data, just one button displays it in alphabetical order and the other does not. This code works only when I start to scroll down and back up, but it does not actually update on button press. Calling myTable reloadData does not do anything either. Any help would be great, thanks!

  • How do I connect StaticListableBeanFactory with ClassPathXmlApplicationContext?

    - by Aaron Digulla
    In the setup of my test cases, I have this code: ApplicationContext context = new ClassPathXmlApplicationContext( "spring/common.xml" ); StaticListableBeanFactory testBeanFactory = new StaticListableBeanFactory(); How do I connect the two in such a way that tests can register beans in the testBeanFactory during setup and the rest of the application uses them instead of the ones defined in common.xml? Note: I need to mix a static (common.xml) and a dynamic configuration. I can't use XML for the latter because that would mean to write 1000 XML files.

  • ViewState Vs Session ... maintaining object through page lifecycle

    - by Kyle
    Can someone please explain the difference between ViewState and Session? More specifically, I'd like to know the best way to keep an object available (continuously setting members through postbacks) throughout the lifecycle of my page. I currently use Sessions to do this, but I'm not sure if it's the best way. For example: SearchObject searchObject; protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { searchObject = new SearchObject(); Session["searchObject"] = searchObject; } else { searchObject = (SearchObject)Session["searchObject"]; } } that allows me to use my searchObject anywhere else on my page but it's kind of cumbersome as I have to reset my session var if I change any properties etc. I'm thinking there must be a better way to do this so that .NET doesn't re-instantiate the object each time the page loads, but also puts it in the global scope of the Page class? Please advise. TIA

  • center menu within the 960 grid

    - by Kyle Monti
    I have been working on 960 grid,(http://960.gs/) and I used an old style menu i've used in the past from a few years ago and for some reason with the 960 grid, the menu is floating left and I want it centered. ul#menu { width:940px; height:61px; background: url(../images/menu_bg.png) no-repeat; list-style:none; padding-top:0; padding-left:0; margin: 0; } ul#menu li { float:left; } ul#menu li a { background: url(../images/menu_splice_color.png) no-repeat scroll top left; display:block; height:61px; position:relative; } ul#menu li a.shel { width:135px; } ul#menu li a.golf { width:84px; background-position:-135px 0px; } ul#menu li a.pro { width:119px; background-position:-219px 0px; } ul#menu li a.event { width:94px; background-position:-338px 0px; } ul#menu li a.member { width:148px; background-position:-432px 0px; } ul#menu li a.bistro { width:91px; background-position:-580px 0px; } ul#menu li a.contact { width:115px; background-position:-671px 0px; } ul#menu li a span { background: url(../images/menu_splice_color.png) no-repeat scroll bottom left; display:block; position:absolute; top:0; left:0px; height:100%; width:100%; z-index:100; } ul#menu li a.shel span { background-position:0px -61px; } ul#menu li a.golf span { background-position:-135px -61px; } ul#menu li a.pro span { background-position:-219px -61px; } ul#menu li a.events span { background-position:-338px -61px; } ul#menu li a.member span { background-position:-432px -61px; } ul#menu li a.bistro span { background-position:-580px -61px; } ul#menu li a.contact span { background-position:-672px -61px; } and my generic html markup is <div class="container_16"> <!-- Navigation Start --> <div class="grid_16"> <ul id="menu"> <li><a href="#" class="shel"><span></span></a></li> <li><a href="#" class="golf"><span></span></a></li> <li><a href="#" class="pro"><span></span></a></li> <li><a href="#" class="events"><span></span></a></li> <li><a href="#" class="member"><span></span></a></li> <li><a href="#" class="bistro"><span></span></a></li> <li><a href="#" class="contact"><span></span></a></li> </ul> </div> <div class="clear"></div> </div> And I use jquery animations to roll over the images. $(function() { $("ul#menu span").css("opacity","0"); $("ul#menu span").hover(function () { $(this).stop().animate({ opacity: 1 }, "slow"); }, function () { $(this).stop().animate({ opacity: 0 }, "slow"); }); });

  • Attempted GCF app for Android

    - by Aaron
    I am new to Android and am trying to create a very basic app that calculates and displays the GCF of two numbers entered by the user. Here is a copy of my GCF.java: package com.example.GCF; import java.util.Arrays; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; public class GCF extends Activity { private TextView mAnswer; private EditText mA, mB; private Button ok; private String A, B; private int iA, iB; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mA = (EditText) findViewById(R.id.entry); mB = (EditText) findViewById(R.id.entry1); ok = (Button) findViewById(R.id.ok); mAnswer = (TextView) findViewById(R.id.answer1); ok.setOnClickListener(new OnClickListener() { public void onClick(View v) { A = mA.getText().toString(); B = mB.getText().toString(); } }); // the String to int conversion happens here iA = Integer.parseInt(A.trim()); iB = Integer.parseInt(B.trim()); while (iA != iB) { int[] nums={ iA, iB, Math.abs(iA-iB) }; Arrays.sort(nums); iA=nums[0]; iB=nums[1]; } updateDisplay(); } private void updateDisplay() { mAnswer.setText( new StringBuilder().append(iA)); } } Any Suggestions? Thank you!

  • How to write curiously recurring templates with more than 2 layers of inheritance?

    - by Kyle
    All the material I've read on Curiously Recurring Template Pattern seems to one layer of inheritance, ie Base and Derived : Base<Derived>. What if I want to take it one step further? #include <iostream> using std::cout; template<typename LowestDerivedClass> class A { public: LowestDerivedClass& get() { return *static_cast<LowestDerivedClass*>(this); } void print() { cout << "A\n"; } }; template<typename LowestDerivedClass> class B : public A<LowestDerivedClass> { public: void print() { cout << "B\n"; } }; class C : public B<C> { public: void print() { cout << "C\n"; } }; int main() { C c; c.get().print(); // B b; // Intentionally bad syntax, // b.get().print(); // to demonstrate what I'm trying to accomplish return 0; } How can I rewrite this code to compile without errors (and output "C\nB\n")?

  • Div behind another div problem.

    - by Kyle Sevenoaks
    Here is a (big) example of the massive problem I am having, when this page is live at euroworker.no/order, it is dynamically generated, I have supplied a static version for people to mess with. All I need is where it says "Endre Valg" to push the div wrapper under it down.. Sounds easy huh? I have tried many many things, I hope that some discussion and even trial and error can help us here. Sorry for the huge amount of code and stuff but this has taken me all day and I am out of ideas. Thanks.

  • Algorithm to determine if array contains n...n+m?

    - by Kyle Cronin
    I saw this question on Reddit, and there were no positive solutions presented, and I thought it would be a perfect question to ask here. This was in a thread about interview questions: Write a method that takes an int array of size m, and returns (True/False) if the array consists of the numbers n...n+m-1, all numbers in that range and only numbers in that range. The array is not guaranteed to be sorted. (For instance, {2,3,4} would return true. {1,3,1} would return false, {1,2,4} would return false. The problem I had with this one is that my interviewer kept asking me to optimize (faster O(n), less memory, etc), to the point where he claimed you could do it in one pass of the array using a constant amount of memory. Never figured that one out. Along with your solutions please indicate if they assume that the array contains unique items. Also indicate if your solution assumes the sequence starts at 1. (I've modified the question slightly to allow cases where it goes 2, 3, 4...) edit: I am now of the opinion that there does not exist a linear in time and constant in space algorithm that handles duplicates. Can anyone verify this? The duplicate problem boils down to testing to see if the array contains duplicates in O(n) time, O(1) space. If this can be done you can simply test first and if there are no duplicates run the algorithms posted. So can you test for dupes in O(n) time O(1) space?

  • Windows 7 Missing Shortnames

    - by Aaron Bush
    I noticed that if you get a Scripting.File object from certain windows files (Example: any wav in C:\Windows\Media) the Scripting.File.ShortPath property shows the long path. Curious I dropped to the command prompt and tried Dir /A /X and sure enough the short paths were missing from all the files in that directory. Anyone know: A.) What that's all about? B.) How to get the short path of a file that doesn't seem to have one?
