  • Data structure for Settlers of Catan map?

    - by templatetypedef
    Hello all- A while back someone asked me if I knew of a nice way to encode the information for the game Settlers of Catan. This would require storing a hexagonal grid in a way where each hex can have data associated with it. More importantly, though, I would need some way of efficiently looking up vertices and edges on the sides of these hexagons, since that's where all the action is. My question is this: is there a good, simple data structure for storing a hexagonal grid while allowing for fast lookup of hexagons, edges between hexagons, and vertices at the intersections of hexagons? I know that general structures like a winged-edge or quad-edge could do this, but that seems like massive overkill. Thanks!

  • AsyncTask, RejectedExecutionException and Task Limit

    - by Samuh
    I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

  • Implement looped movement animation with tap to cancel

    - by Nader
    Hi All; My app is based around a grid and an image that moves within a grid that is contained within a scrollview. I have an imageview that I am animating from one cell to another in time with a slow finger movement and recentering the scrollview. That is rather straight forward. I have also implement the ability to detect a swipe and therefore move the image all the way to the end of the grid and the uiscrollview recentering. I have even implemented the ability to detect a subsequent tap and freeze the swiped movement. The issue with the swipe movement is that the UIScrollView will scroll all the way to the end before the Image reaches the end and so I have to wait for the image to arrive. Also, when I freeze the movement of the image, I have to re-align the image to a cell (which I can do). I have come to the realization that I have to animate the image one cell at a time for swipes and recentering the uiscrollview before moving the image to the next cell. I have attempted to implement this but I cannot come up with a solution that works or works properly. Can anyone suggest how I go about implementing this? Even if you are able to put up code from a different example or sudo code, it would help a lot as I cannot workout how this should be done, should I be using selectors, a listener in delegates, I just simply lack the experience to solve this design pattern. Here is some code: Note that the sprite is an UIImageView - (void)animateViewToPosition:(SpriteView *)sprite Position:(CGPoint)pos Duration:(CFTimeInterval)duration{ CGMutablePathRef traversePath = CGPathCreateMutable(); CGPathMoveToPoint(traversePath, NULL, sprite.center.x, sprite.center.y); CGPathAddLineToPoint(traversePath, NULL, pos.x, pos.y); CAKeyframeAnimation *traverseAnimation = [CAKeyframeAnimation animationWithKeyPath:kAnimatePosition]; traverseAnimation.duration = duration; traverseAnimation.removedOnCompletion = YES; traverseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; traverseAnimation.delegate = sprite; traverseAnimation.path = traversePath; CGPathRelease(traversePath); [sprite.layer addAnimation:traverseAnimation forKey:kAnimatePosition]; sprite.center = pos;

    Question:- Page is a typical search page with few filters on it. When search for records based on filters, it shows result in Gridview. From grid view records, user can click on any record to see the details which takes the focus on new page. Its working fine so far. Now when user comes back from details page to search page. I am loosing selected filters values and no result in grid view. How can i display selected filters and its results in gridview when user is coming back on search page? Any example etc.?

  • Building Visual studio like application, need inputs..

    - by akjoshi
    Hi, I am working on a Visual studio like application i.e. hava a tolbox, an editor and property grid similar to VS. ser can drag and drop the controls(custom and third party) to the editor window and perform operations like resize, move, align, group etc.; Properties of that control needs to be displayed in property grid and user can update them from there. As per my current understanding I will have to extend the Canvas to create my own editor and and Interface for controls which it supports; Each supported control will have to implemnt this interface so that it can be placed in our editor. Something similar to this - http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part4.aspx Looking forward for any kind of help, comment or links.

  • Save data in bulk.

    - by Muhammad Kashif Nadeem
    I have a window having multiple tabs. Each tab having different grids. I want to save all changes on any tab on any grid in bulk. I mean I have one save button which will save all changes in any grid on any tab. I think DataTables will work fine here. Can you suggest me that it is good to use DataTables to ADD/Edit data and save data in bulk using these DataTables OR is there any better way to achieve this. My DAL is generated from LLBLGen Pro (ORM) but you are open to suggest me a solution. Thanks. Edit: I am using Telerik controls so I can get all data in DataTable like DataTable dtProducts = this.radGridView1.DataSource as DataTable;

  • NetLogo 4.1 - implementation of a motorway ( Problem creating collision of cars )

I want to know how to create the collision of the cars. I can't think of any idea. As you notice my agent has almost the same size as the patch (I set it to 0.9 so that you can distinguish the space between 2 cars when they are set next to each other and I round the coordinates so that they are set to the centre of the patch). In my accelerate procedure I set my agent to turn left, move 1, turn right in a loop. I want to know if there's a command that lets me make the agent jump from one lane to the other (to the patch next to it on its left) without making it turn and move. And last, if you notice the code i created the car checks the patch that is next to it on the lane on its left and the patch in front of it and the back of it. So if the 3 patches on its left are empty then it can change lane. The fuzzy part is that when i run the setup and I press Go sometimes (not always) the car goes out of the 3 basic lanes. To understand this I have 7 lanes. The middle one which I don't use which is lane 0. Then there are 3 lanes on top of lane 0 and 3 below it. So the code I am using refers to the upper 3 lanes where I set the cars but for some reason some of the cars change lane and go to lane -3 then -2 and so forth. If someone can give me a tip I would really appreciate it. Thank you in advance. Tip: if you want to try this code in netlogo keep in mind that on interface tab I have 2 buttons one setup and one go as well as 3 sliders with names: number_of_cars , speed-up , slow-down.

  • Pros and cons of using JSON for WCF service

    - by brz dot net
    What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

  • WPF RichTextBox with no width set

    - by Mick
    I have the following XAML code: <Window x:Class="RichText_Wrapping.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1"> <Grid> <RichTextBox Height="100" Margin="2" Name="richTextBox1"> <FlowDocument> <Paragraph> This is a RichTextBox - if you don't specify a width, the text appears in a single column </Paragraph> </FlowDocument> </RichTextBox> </Grid> ... If you create this window in XAML, you can see that when you don't specify a width for the window, it wraps the text in a single column, one letter at a time. Is there something I'm missing? If it's a known deficiency in the control, is there any workaround? Thanks, Michael

  • Calculate total by javascript in gridview with paging

    - by louis
    Without paging function, i can loop through the gridview by using var sum = 0; var gridViewCtlId = '<%=timesheetView.ClientID%>'; var grid = document.getElementById(gridViewCtlId); var gridLength = grid.rows.length; so with gridLength i can loop through the gridview to sum all rows. However, when I use paging event of gridview, i use the page size to loop through all rows, but it occurs errors because the last page may not have enough rows. So would you please to help me how to get the rows in the each page of gridview?

  • Would anyone tell me how to fetch the media:thumb element's attribute from a json feed?

    - by ash
    I made a yahoo pipe that pulls up the atoms as json format; however, I can fetch and display all the elements in my html page except for the element's attribute. Would anyone tell me how to fetch the media:thumb element's attribute from a json feed? I am pasting the html page's code with javascript. If you save the html page and then view it in browser, you will see that all the necessary elements get output at html page except for the media:thumb as I cannot display the attribute of media:thumb when the feed is formatted as json. I am also pasting the some portion of the json feed so that you can have an idea what i am talking about. Please tell me how to retrieve attribute from media:thumb element of a json feed by using plain javascript but no server side code or javascript library.

  • Rapidly prototype GUI's...

    - by Donovan
    G'Day, I am looking to prototype a windows based GUI. Ideally I would like: Be able create new GUI's and change existing ones quickly The resulting "thing" to be self contained Have the ability to include limited data where necessary ie. When showing a grid including the headers and perhaps a few rows of data for the grid. Allow clickable hotspots that either allow a new screen to be shown or perhaps an explanation hint. I have been using Visio 2003 for this kind of thing and then producing a PDF. However it has some disadvantages: Including data for grids is not possible You cannot include hotspots to allow changing of tabs within the workbook. eg Click on a button and it opens a different tab. If possible a free / open source application would be preferable but a low priced commercial application would also be good. All pointers and suggestions greatly appreciated.Rapid

  • I've got a ComboBox that's giving me grief in WPF using the MVVM pattern

    - by Mike
    Here's my code: <ComboBox Grid.Column="1" Grid.Row="9" ItemsSource="{Binding Path=PriorityEntries}" SelectedItem="{Binding Path=Priority,Mode=TwoWay}"/> The comboBox is bound properly with PriorityEntries, and when i change the value of the comboBox the "set" of the bound property(Priority) is called setting it to what it needs to be. However, when i close the UserControl that this combobox resides, it calls the set property again with a value of null and then sets what the selectedItem was to null. Why is the comboBox being bound again when I close the usercontrol. I tried setting the mode to OneTime, but that won't reflect any changes...

  • WPF 4 Datagrid with ComboBox

    - by Doug
    I have a WPF 4 app with a ComboBox embedded in a DataGrid. The ComboBox is in a template column that displays the combobox when in edit mode but just a TextBlock otherwise. If I edit the cell and pick a new value from the combobox, when leaving the cell, the TextBlock in view mode does not reflect the new value. Ultimately, the new value gets saved and is displayed when the window is refreshed but it does not happen while still editing in the grid. Here are the parts that are making this more complicated. The grid and the combobox are bound to different ItemsSource from the EnityFramework which is tied to my database. For this problem, the grid is displaying project members. The project member name can be picked from the combobox which gives a list of all company employees. Any ideas on how to tie the view mode of the DataGridColumnTemplate to the edit value when they are pointing to different DataSources? Relevant XAML <Window.Resources> <ObjectDataProvider x:Key="EmployeeODP" /> </Window.Resources> <StackPanel> <DataGrid Name="teamProjectGrid" AutoGenerateColumns="false" ItemsSource="{Binding Path=ProjectMembers}" <DataGrid.Columns> <DataGridTemplateColumn Header="Name" x:Name="colProjectMember"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=ProjectMemberFullName}" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> <DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox x:Name="ProjectMemberCombo" IsReadOnly="True" DisplayMemberPath="FullName" SelectedValue="{Binding Path=Employee}" ItemsSource="{Binding Source={StaticResource EmployeeODP}}" /> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate> </DataGridTemplateColumn> <DataGridTextColumn x:Name="colProjectRole" Binding="{Binding Path=ProjectRole}" Header="Role" /> </DataGrid.Columns> </DataGrid> </StackPanel> Relevant Code Behind this.DataContext = new MyEntityLibrary.MyProjectEntities(); ObjectDataProvider EmployeeODP= (ObjectDataProvider)FindResource("EmployeeODP"); if (EmployeeODP != null) { EmployeeODP.ObjectInstance = this.DataContext.Employees; }

  • dojo datagrid will make the page "jump" when sorting is changed

    - by Select0r
    Hi, I have a Dojo Datagrid in one of my pages (which contains more content) and the following problem occurs: As soon as I click on a column header to change the sorting, the page will jump up as if I clicked on some HTML-anchor. Funny enough, the page jump will make the grid show only the first two rows after it jumped, instead of (e.g.) have the grid start at the top of the page after the jump, which is the expected behaviour if an anchor is used. The problem occurs in different browsers (tested: Firefox 3.6, Opera 10, IE6), so I guess it might be a Dojo-problem/-bug. Any ideas to make this annoying behaviour stop? Greetings, Select0r PS: this seems to describe a similar problem, only for JQuery (and unfortunately without a solution, too)
