  • How to create file of files?

    - by TheMachineCharmer
    class Node { FooType Data; // I can save Data to file with extension .foo void Save() { // save Data to .foo file } } Now , class Graph { List<Node> Nodes; void Save() { foreach(Node node in Nodes) { node.Save(); } } } Now when I invoke someGraph.Save(); then it creates Nodes.Count number of files. I would like to appear those files as one file with extension somename.graph and be able to read it again as Nodes. How can I do this? Is there a way to bundle files into a single different file?

  • Displaying a collection of controls in a specific way in WPF

    - by Alvaro
    I have a collection of controls "MyCollection" wich changes in the Runtime. And I have to follow some constraints for that, for example: If my parameter "MyCollection.Count = 4" the property "NumberOfcolumns" will have the value 2, in order to create new Lines, and show the controls Two per Two. This is how I'm displaying my collection : <ItemsControl ItemsSource="{Binding MyCollection}" BorderThickness="0" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate > <UniformGrid Columns="{Binding NumberOfColumns}" VerticalAlignment="Center" HorizontalAlignment="Center" Background="Transparent"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> The problem is that my controls have different sizes, and as In UniformGrids, Cells are uniform... My design is not really pretty, because I have little controls shown in big Cells !! Can someone help me to solve this problem ? NB: Please give me a detailled solution if possible, not something like : "Use WrapPanel..."

  • Why is the dictionary debug visualizer less useful in Visual Studio 2010?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b");

  • Creating a program to find longest path

    - by stef89
    Hi everyone, I'm fairly new to programming and I'm having a few problems. Basically I have to make a function that will find the lengths of all the paths through a network diagram. I've been working on this for hours but I can't seem to get anywhere. Using recursion I can navigate through every path but I'm just unsure as to how I should record the lengths of the paths. Any help would be greatly appreciated. Thanks! $dependencies = array("","","","1","3","4,2"); $durations = array("5","3","4","11","9","10"); function tracePath($path,$dependencies,$durations,$returnArray=array()) { if($dependencies[$path] != "") { $currentTaskDependencies = preg_split("/[\s]*[,][\s]*/", $dependencies[$path]); for($i=0;$i<count($currentTaskDependencies);$i++) { tracePath($currentTaskDependencies[$i]-1,$dependencies,$durations,$returnArray[$i]); } } return $returnArray; } tracePath(6,$dependencies,$durations);

  • Proper way to have an endless worker thread?

    - by Neil N
    I have an object that requires a lot of initialization (1-2 seconds on a beefy machine). Though once it is initialized it only takes about 20 miliseconds to do a typical "job" In order to prevent it from being re-initialized every time an app wants to use it (which could be 50 times a second or not at all for minutes in typical usage), I decided to give it a job que, and have it run on its own thread, checking to see if there is any work for it in the que. However I'm not entirely sure how to make a thread that runs indefinetly with or without work. Here's what I have so far, any critique is welcomed private void DoWork() { while (true) { if (JobQue.Count > 0) { // do work on JobQue.Pop() } else { System.Threading.Thread.Sleep(50); } } } After thought: I was thinking I may need to kill this thread gracefully insead of letting it run forever, so I think I will add a Job type that tells the thread to end. Any thoughts on how to end a thread like this also appreciated.

  • Add HTML Id's to tags in .aspx file

    - by slandau
    So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to. Then they click start, and this runs private void btnStart_Click(object sender, EventArgs e) { for (int i = 0; i < listFiles.CheckedItems.Count; i++) { } } It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the id="thisItemId" attribute to each tag that's like a , , , , , etc....

  • What good timesheet should and shouldn't have for a small (non programming) 50 people company?

    - by MadBoy
    I'm sure most people here had to fill at least one time sheet in their life that made their life miserable, hell it's even the worst time taker ever especially after you have to fill it in hurry. I will be developing some simple TimeSheet application for a small company of 50 people (non programming related, it's actually 4 companies working together) and would like it to be user friendly and as less disturbing as possible. So what in your opinion makes it a good timesheet (lack of it doesn't count :p), what data it should store? Should be only hours per day with possibility to choose project, company and simple overview what you have worked on like: Day 1, 3:00, 'Company 1', 'Project5', 'Name', Short Overview Day 1, 5:00, 'Company 2', 'Project6', 'Name', Short Overview Or should it gather more data? Would it be realy bad if it were an WinForms application considering that I don't know ASP.NET or any other web based language? I would be deploying it using ClickOnce or so.

  • Resharper code format linebreaks

    - by mizipzor
    Im trying to setup the code formatting in ReSharper. Limiting each line to a maximum count of characters, it seems to want to place casts on a separate line. Like so: string mystring = (string) MyStringConverter.convert(toconvert, typeof(string), null, null); I cant seem to be able to find the correct combination of settings to not have this on three lines. Im looking for something like this: string mystring = (string) MyStringConverter.convert( toconvert, typeof(string), null, null); Where the linebreak occurs is not that important, I guess I cant be to picky when I want to limit the line length. But three lines is a bit much. Does anyone know the/any correct combination of settings to make it only cut the line once?

  • Implementing implicitly shared classes outside of Qt

    - by Timothy Baldridge
    I'm familiar with the way Qt uses D-pointers for managing data. How do I do this in my code? I tried this method: 1) move all data into a struct 2) add a QAtomicInt to the struct 3) implement a = operator and change my constructor/deconstructor to check-up on the reference count. The issue is, when I go to do a shallow copy of the object, I get an error about QObject declaring = as private. How then do I accomplish this? Here's an example of my copy operator: HttpRequest & HttpRequest::operator=(const HttpRequest &other) { other.d->ref.ref(); if (!d->ref.deref()) delete d; d = other.d; return *this; } Am I going about this the wrong way?

  • PHP Array To Class Static Public Values.

    - by what
    I want to make a class that has all the values of an array as a static object in that class. For example: $vars=array(... );//some array with actual values $Class_code='class MyClass{'; for($i=0; $i<count($vars); $i++){ $Class_code.='static public $'.strval($vars[i]).';'; } eval($Class_code.'}'); /* When I echo the line above it says that the vars for MyClass (MyClass::vars) are missing even with strval(). */ So, how can I get $vars[i] to be a string if strval didn't work?

  • Trying to get JQuery Autocomplete working on Asp.Net page.

    - by JasonMHirst
    Can someone shed some light on the problem please: I have the following: $(document).ready(function () { $("#txtFirstContact").autocomplete({url:'http://localhost:7970/Home/FindSurname' }); }); On my Asp.Net page. The http request is a function on an MVC Controller and that code is here: Function FindSurname(ByVal surname As String, ByVal count As Integer) Dim sqlConnection As New SqlClient.SqlConnection sqlConnection.ConnectionString = My.Settings.sqlConnection Dim sqlCommand As New SqlClient.SqlCommand sqlCommand.CommandText = "SELECT ConSName FROM tblContact WHERE ConSName LIKE '" & surname & "%'" sqlCommand.Connection = sqlConnection Dim ds As New DataSet Dim da As New SqlClient.SqlDataAdapter(sqlCommand) da.Fill(ds, "Contact") sqlConnection.Close() Dim contactsArray As New List(Of String) For Each dr As DataRow In ds.Tables("Contact").Rows contactsArray.Add(dr.Item("ConSName")) Next Return Json(contactsArray, JsonRequestBehavior.AllowGet) End Function As far as I'm aware, the Controller is returning JSON data, however I don't know if the Function Parameters are correct, or indeed if the format returned is interprettable by the AutoComplete plugin. If anyone can assist in the matter I'd really appreciate it.

  • MySQL: filling empty fields with zeroes when using GROUP BY

    - by SaltLake
    I've got MySQL table CREATE TABLE cms_webstat ( ID int NOT NULL auto_increment PRIMARY KEY, TIMESTAMP_X timestamp DEFAULT CURRENT_TIMESTAMP, # ... some other fields ... ) which contains statistics about site visitors. For getting visits per hour I use SELECT hour(TIMESTAMP_X) as HOUR , count(*) AS HOUR_STAT FROM cms_webstat GROUP BY HOUR ORDER BY HOUR DESC which gives me | HOUR | HOUR_STAT | | 24 | 15 | | 23 | 12 | | 22 | 9 | | 20 | 3 | | 18 | 2 | | 15 | 1 | | 12 | 3 | | 9 | 1 | | 3 | 5 | | 2 | 7 | | 1 | 9 | | 0 | 12 | And I'd like to get following: | HOUR | HOUR_STAT | | 24 | 15 | | 23 | 12 | | 22 | 9 | | 21 | 0 | | 20 | 3 | | 19 | 0 | | 18 | 2 | | 17 | 0 | | 16 | 0 | | 15 | 1 | | 14 | 0 | | 13 | 0 | | 12 | 3 | | 11 | 0 | | 10 | 0 | | 9 | 1 | | 8 | 0 | | 7 | 0 | | 6 | 0 | | 5 | 0 | | 4 | 0 | | 3 | 5 | | 2 | 7 | | 1 | 9 | | 0 | 12 | How should I modify the query to get such result?

  • iPhone: Add background button to view when UITableView has no cells

    - by Nic Hubbard
    I have a UITableViewController, when there is no data to populate the UITableView, I want to add a button, which uses an image. So, rather than the user seeing a tableview with no records, they will see an image that says, "No records have been added, Tap to add one", then they click and we create a new one. I assumed I would just hide the UITableView, then create the button, but I never see the button. Here I am using: if ([[fetchedResultsController sections] count] == 0) { self.tableView.hidden = YES; // Create button w/ image UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(0, 0, 100, 50); [btn setImage:[UIImage imageNamed:@"no-rides.png"] forState:UIControlStateNormal]; [self.view addSubview:btn]; } Ideas on why I would never see the button? When I show this view, it seems to have a transparent background for a second, then changes white...

  • MySQL break out group clause from subquery

    - by Anton Gildebrand
    Here is my query SELECT COALESCE(js.name,'Lead saknas'), count(j.id) FROM jobs j LEFT JOIN job_sources js ON j.job_source=js.id LEFT JOIN (SELECT * FROM quotes GROUP BY job_id) q ON j.id=q.job_id GROUP BY j.job_source The problem is that it's allowed for each job to have more than one quote. Because of that i group the quotes by job_id. Now sure, this works. But i don't like the solution with a subquery. How can i break out the group clause from the subquery to the main query? I have tried to add q.job_id to the main group clause, both before and after the existing one but don't get the same results.

  • How can I pull data from a SQL Database that spans an academic year?

    - by Eric Reynolds
    Basically, I want to pull data from August to May for a given set of dates. Using the between operator works as long as I do not cross the year marker (i.e. BETWEEN 8 AND 12 works -- BETWEEN 8 AND 5 does not). Is there any way to pull this data? Here is the SQL Query I wrote: SELECT count(*), MONTH(DateTime) FROM Downloads WHERE YEAR(DateTime) BETWEEN 2009 AND 2010 AND MONTH(DateTime) BETWEEN 8 AND 5 GROUP BY MONTH(DateTime) ORDER BY MONTH(DateTime)" Any help is appreciated. Thanks, Eric R.

  • Get the last N rows in the database in order?

    - by Kristopher
    Let's say I have the following database table: record_id | record_date | record_value -----------+-------------+-------------- 1 | 2010-05-01 | 195.00 2 | 2010-07-01 | 185.00 3 | 2010-09-01 | 175.00 4 | 2010-05-01 | 189.00 5 | 2010-06-01 | 185.00 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 I want to grab the last 5 rows with the data ordered by record_date ASC. This is easy to do with: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET 4 Which would give me: record_id | record_date | record_value -----------+-------------+-------------- 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 3 | 2010-09-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 But how do I do this when I don't know how many records there are and can't compute the magic number of 4? I've tried this query, but if there are less than 5 records, it results in a negative OFFSET, which is invalid: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET (SELECT COUNT(*) FROM mytable) - 5; So how do I accomplish this?

  • Loop a UIScrollviw with ViewControllers

    Hi I'm trying to create a UIScrollView with loop that contains a collection of ViewControllers. The answer to this question here shows the code that is the basis for what I'm trying to do. It uses images instead of viewControllers. I've managed to get the all the viewControllers loaded (4) and displaying but the first view which is a duplicate of the last viewController is blank. I've tried creating a copy of this viewController and adding it to the array but this messes up the transition / count. Any suggestions?

  • iPhone UITableView populating variable rows sections from flat array

    - by Biko
    I thought that would be very common and easy iPhone App. In the main app I connect to database, retrieve values from database (NSDate converted to NSString)n and put into single array. The in one of the views I populate UITableView with elements from the array. UITableView is grouped (sections). I step through array to discover number of sections (change section if new day). How do I retrieve correct element of array in cellForRowAtIndexPath? IndexPath.section and IndexPath.row seem useless as row starts count from zero for each section. If number of rows in each section was the same it would have been easy: [arryData objectAtIndex:(indexPath.row)+indexPath.section*[tblMatchesView numberOfRowsInSection:indexPath.section]]; But number of rows in each section varies... :-)

Does anyone know any method so that myInterval is cleared on .load, without needing to put the javascript outside of the loaded file?
