  • How to print each object in a collection in a separate page in Silverlight

    - by Ash
    I would like to know if its possible to print each object in a collection in separate pages using Silverlight printing API. Suppose I have a class Label public class Label { public string Address { get; set; } public string Country { get; set; } public string Name { get; set; } public string Town { get; set; } } I can use print API and print like this. private PrintDocument pd; private void PrintButton_Click(object sender, RoutedEventArgs e) { pd.Print("Test Print"); } private void pd_PrintPage(object sender, PrintPageEventArgs e) { Label labelToPrint = new Label() { Name = "Fake Name", Address = "Fake Address", Country = "Fake Country", Town = "Town" }; var printpage = new LabelPrint(); printpage.DataContext = new LabelPrintViewModel(labelToPrint); e.PageVisual = printpage; } LabelPrint Xaml <StackPanel x:Name="LayoutRoot" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock Text="{Binding Name}" /> <TextBlock Text="{Binding Address}" /> <TextBlock Text="{Binding Town}" /> <TextBlock Text="{Binding Country}" /> </StackPanel> Now, say I've a collection of Label objects, List<Label> labels = new List<Label>() { labelToPrint, labelToPrint, labelToPrint, labelToPrint }; How can I print each object in the list in separate pages ? Thanks for any suggestions ..

  • Jquery Returning values to original

    - by Cam
    So my script works perfectly, but here is the issue, I have buttons (Sprite action here) that are 40px height, but the top 20 only shows perfectly. When you click the button ie img the bottom 20px show perfecto! but... Issue, i included in my script a way to return all others to there default (only one should be selected) now, how can I fix this issue that I seem unable to correct as I can select multiple of them ** USERS can switch ** The last part of the script that is the issue. Thanks $(document).ready(function() { $('.form_sub').hide(); $('.theader').addClass('active'); $('.theader_t').click(function() { $('.form_header').show(); $('.form_sub').hide(); $('.theader').addClass('active'); $('.sub_theader').removeClass('active'); }); $('.sub_theader_t').click(function() { $('.form_header').hide(); $('.form_sub').show(); $('.theader').removeClass('active'); $('.sub_theader').addClass('active'); }); $('.top_head_img').click(function() { $(this).css({ position: 'relative', bottom: '20px' }).siblings().css( 'bottom', '0' ); }); }); <ul class="top_head"> <li> <a href="javascript:void(0)" onClick="selectPic5('top');"><img src="custom/images/top2.jpg" alt="Left" border="0" class="top_head_img"/></a> </li> <li> <a href="javascript:void(0)" onClick="selectPic5('center');"><img src="custom/images/mid2.jpg" alt="Center" border="0" class="top_head_img"/></a> </li> <li> <a href="javascript:void(0)" onClick="selectPic5('bottom');"><img src="custom/images/bot2.jpg" alt="Right" border="0" class="top_head_img"/></a> </li> </ul>

  • Swt file dialog too much files selected?

    - by InsertNickHere
    Hi there, the swt file dialog will give me an empty result array if I select too much files (approx. 2500files). The listing shows you how I use this dialog. If i select too many sound files, the syso will show 0. Debugging tells me, that the files array is empty in this case. Is there any way to get this work? FileDialog fileDialog = new FileDialog(mainView.getShell(), SWT.MULTI); fileDialog.setText("Choose sound files"); fileDialog.setFilterExtensions(new String[] { new String("*.wav") }); Vector<String> result = new Vector<String>(); fileDialog.open(); String[] files = fileDialog.getFileNames(); for (int i = 0, n = files.length; i < n; i++) { if( !files[i].contains(".wav")) { System.out.println(files[i]); } StringBuffer stringBuffer = new StringBuffer(); stringBuffer.append(fileDialog.getFilterPath()); if (stringBuffer.charAt(stringBuffer.length() - 1) != File.separatorChar) { stringBuffer.append(File.separatorChar); } stringBuffer.append(files[i]); stringBuffer.append(""); String finalName = stringBuffer.toString(); if( !finalName.contains(".wav")) { System.out.println(finalName); } result.add(finalName); } System.out.println(result.size()) ;

  • What is the best way to handle the Connections to MySql from c#

    I am working on a c# application which connects to MySql server. There are about 20 functions which will connect to database. This application will be deployed in 200 over machines. I am using the below code to connect to my database which is identical for all the functions. The problem is, i can some connections were not closed and still alive when deployed in 200 over machines. Connection String : <add key="Con_Admin" value="server=test-dbserver; database=test_admindb; uid=admin; password=1Password; Use Procedure Bodies=false;" /> Declaration of the connection string Globally in application [Global.cs] : public static MySqlConnection myConn_Instructor = new MySqlConnection(ConfigurationSettings.AppSettings["Con_Admin"]); Function to query database : public static DataSet CheckLogin_Instructor(string UserName, string Password) { DataSet dsValue = new DataSet(); //MySqlConnection myConn = new MySqlConnection(ConfigurationSettings.AppSettings["Con_Admin"]); try { string Query = "SELECT accounts.str_nric AS Nric, accounts.str_password AS `Password`," + " FROM accounts " + " WHERE accounts.str_nric = '" + UserName + "' AND accounts.str_password = '" + Password + "\'"; MySqlCommand cmd = new MySqlCommand(Query, Global.myConn_Instructor); MySqlDataAdapter da = new MySqlDataAdapter(); if (Global.myConn_Instructor.State == ConnectionState.Closed) { Global.myConn_Instructor.Open(); } cmd.ExecuteScalar(); da.SelectCommand = cmd; da.Fill(dsValue); Global.myConn_Instructor.Close(); } catch (Exception ex) { Global.myConn_Instructor.Close(); ExceptionHandler.writeToLogFile(System.Environment.NewLine + "Target : " + ex.TargetSite.ToString() + System.Environment.NewLine + "Message : " + ex.Message.ToString() + System.Environment.NewLine + "Stack : " + ex.StackTrace.ToString()); } return dsValue; }

  • Howto use predicates in LINQ to Entities for Entity Framework objects

    - by user274947
    I'm using LINQ to Entities for Entity Framework objects in my Data Access Layer. My goal is to filter as much as I can from the database, without applying filtering logic on in-memory results. For that purpose Business Logic Layer passes a predicate to Data Access Layer. I mean Func<MyEntity, bool> So, if I use this predicate directly, like public IQueryable<MyEntity> GetAllMatchedEntities(Func<MyEntity, Boolean> isMatched) { return qry = _Context.MyEntities.Where(x => isMatched(x)); } I'm getting the exception [System.NotSupportedException] --- {"The LINQ expression node type 'Invoke' is not supported in LINQ to Entities."} Solution in that question suggests to use AsExpandable() method from LINQKit library. But again, using public IQueryable<MyEntity> GetAllMatchedEntities(Func<MyEntity, Boolean> isMatched) { return qry = _Context.MyEntities.AsExpandable().Where(x => isMatched(x)); } I'm getting the exception Unable to cast object of type 'System.Linq.Expressions.FieldExpression' to type 'System.Linq.Expressions.LambdaExpression' Is there way to use predicate in LINQ to Entities query for Entity Framework objects, so that it is correctly transformed it into a SQL statement. Thank you.

  • Is it possible to get the parsed text of a SqlCommand with SqlParameters?

    - by Burg
    What I am trying to do is create some arbitrary sql command with parameters, set the values and types of the parameters, and then return the parsed sql command - with parameters included. I will not be directly running this command against a sql database, so no connection should be necessary. So if I ran the example program below, I would hope to see the following text (or something similar): WITH SomeTable (SomeColumn) AS ( SELECT N':)' UNION ALL SELECT N'>:o' UNION ALL SELECT N'^_^' ) SELECT SomeColumn FROM SomeTable And the sample program is: using System; using System.Data; using System.Data.SqlClient; namespace DryEraseConsole { class Program { static void Main(string[] args) { const string COMMAND_TEXT = @" WITH SomeTable (SomeColumn) AS ( SELECT N':)' UNION ALL SELECT N'>:o' UNION ALL SELECT @Value ) SELECT SomeColumn FROM SomeTable "; SqlCommand cmd = new SqlCommand(COMMAND_TEXT); cmd.CommandText = COMMAND_TEXT; cmd.Parameters.Add(new SqlParameter { ParameterName = "@Value", Size = 128, SqlDbType = SqlDbType.NVarChar, Value = "^_^" }); Console.WriteLine(cmd.CommandText); Console.ReadKey(); } } } Is this something that is achievable using the .net standard libraries? Initial searching says no, but I hope I'm wrong.

  • How to write an intersects for Shapes in android

    - by Rafael T
    I have an written an Object called Shape which has a Point representing the topLeftCorner and a Dimension with represents its width and height. To get the topRightCorner I can simply add the width to the topLeftPoint.x. I use to rotate them on a certain degree around their center. The problem after the rotation is, that my intersects(Shape) method fails, because it does not honor the rotation of the Shapes. The rotation will be the same for each Shape. My current implementation looks like this inside my Shape Object: public boolean intersects(Shape s){ // functions returning a Point of shape s return intersects(s.topLeft()) || intersects(s.topRight()) || intersects(s.bottomLeft()) || intersects(s.bottomRight()) || intersects(s.leftCenter()) || intersects(s.rightCenter()) || intersects(s.center()); } public boolean intersects(Point p){ return p.x >= leftX() && p.x <= rightX() && p.y >= topY() && p.y <= bottomY(); } Basically I need functions like rotatedLeftX() or rotatedTopRight() to work properly. Also for that calculation I think it doesn't matter when the topLeft point before a rotation of ie 90 will turn into topRight... I already read this and this Question here, but do not understand it fully.

  • WCF Web Service - Service Unavaiable

    - by born to hula
    I have a WCF Web Service which is kept under an Application Pool on IIS. Lately I've been getting "Service Unavaiable" when I'm trying to make calls to this Web Service. The first thing I tried to do was restarting the Application Pool. I did it and after a couple of seconds, it crashed and stopped. Looking at the Event Viewer, I found these messages, which by the moment couldn't help me to find where the problem is. A process serving application pool 'X' reported a failure. The process id was '11616'. The data field contains the error number. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. After getting a couple of these, I got this one: Application pool 'X' is being automatically disabled due to a series of failures in the process(es) serving that application pool. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I've already checked permissions and Application Pool configurations but everything seems to be OK. Have anyone been through this? Thanks in advance.

  • Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work. Wh

    - by Kevin
    I'm just playing around with some code. I create an Activity and simply do something like this: long lo = currentTimeMillis(); System.out.println(lo); lo *= 3; System.out.println(lo); SystemClock.setCurrentTimeMillis(lo); System.out.println( currentTimeMillis() ); Yes, in my AndroidManifest.xml, I've added: <uses-permission android:name="android.permission.SET_TIME"></uses-permission> <uses-permission android:name="android.permission.SET_TIME_ZONE"></uses-permission> Nothing changes. The SystemClock is never reset...it just keeps on ticking. The error that I'm getting just says that the permission "SET_TIME" was not granted to the program. Protection level 3. The permissions are there...and in the API for 2.2 it says that this feature is supported now. I have no idea what I'm doing wrong. If android.content.Intent; comes into play, please explain. I don't really understand what the idea behind intents! Thanks for any help!

  • ASP.NET 2.0 + Firefox/Safari - UI Issues?

    - by Tejaswi Yerukalapudi
    I'm developing on a system that was originally developed five years ago. I don't have access to the complete source code of the system, but it is completely driven by XML and runs on ASP.NET 2.0. This was originally written for IE6, but since Microsoft has officially decided to dump it, we moved to IE7. Some javascript is added on the client side, but nothing that changes the UI has been done. (We had to integrate a credit card reader into the system) This code is accessed primarily on tablet PCs running windows, but I'd like to persuade my company to use the iPad. [The tablet somehow costs around 3k$. I think selling a 3000$ device to a client when you have the iPad for 500$ is ridiculous.] Now, my problem is if we open it in any other browser (Tested it on safari / firefox), the UI is completely messed up with elements completely out of place. Doesn't ASP.NET generate HTML that runs on any browser? My second question is if there are any credit card readers available in the market that integrate with the iPad. I don't really care about the software part as it's taken care by our company, I just need it to read the card details and post it to the server. Thanks, Teja.

  • How to write efficient code for extracting Noun phrases?

    - by Arun Abraham
    I am trying to extract phrases using rules such as the ones mentioned below on text which has been POS tagged 1) NNP - NNP (- indicates followed by) 2) NNP - CC - NNP 3) VP - NP etc.. I have written code in this manner, Can someone tell me how i can do in a better manner. List<String> nounPhrases = new ArrayList<String>(); for (List<HasWord> sentence : documentPreprocessor) { //System.out.println(sentence.toString()); System.out.println(Sentence.listToString(sentence, false)); List<TaggedWord> tSentence = tagger.tagSentence(sentence); String lastTag = null, lastWord = null; for (TaggedWord taggedWord : tSentence) { if (lastTag != null && taggedWord.tag().equalsIgnoreCase("NNP") && lastTag.equalsIgnoreCase("NNP")) { nounPhrases.add(taggedWord.word() + " " + lastWord); //System.out.println(taggedWord.word() + " " + lastWord); } lastTag = taggedWord.tag(); lastWord = taggedWord.word(); } } In the above code, i have done only for NNP followed by NNP extraction, how can i generalise it so that i can add other rules too. I know that there are libraries available for doing this , but wanted to do this manually.

  • Is it safe to silently catch ClassCastException when searching for a specific value?

    - by finnw
    Suppose I am implementing a sorted collection (simple example - a Set based on a sorted array.) Consider this (incomplete) implementation: import java.util.*; public class SortedArraySet<E> extends AbstractSet<E> { @SuppressWarnings("unchecked") public SortedArraySet(Collection<E> source, Comparator<E> comparator) { this.comparator = (Comparator<Object>) comparator; this.array = source.toArray(); Collections.sort(Arrays.asList(array), this.comparator); } @Override public boolean contains(Object key) { return Collections.binarySearch(Arrays.asList(array), key, comparator) >= 0; } private final Object[] array; private final Comparator<Object> comparator; } Now let's create a set of integers Set<Integer> s = new SortedArraySet<Integer>(Arrays.asList(1, 2, 3), null); And test whether it contains some specific values: System.out.println(s.contains(2)); System.out.println(s.contains(42)); System.out.println(s.contains("42")); The third line above will throw a ClassCastException. Not what I want. I would prefer it to return false (as HashSet does.) I can get this behaviour by catching the exception and returning false: @Override public boolean contains(Object key) { try { return Collections.binarySearch(Arrays.asList(array), key, comparator) >= 0; } catch (ClassCastException e) { return false; } } Assuming the source collection is correctly typed, what could go wrong if I do this?

    hi, i have a windows service that get user details and save the result into log text file. and, my problem is when i shut down or log off my system, i also would like to save the time that i down my system into that log file. but, i don't know how to do that. I checked the winproc method to detect shutdown operation but i was not able to use it on window service, on googling found it can be used with forms only. how can we detect user have clicked shutdown or log off and do some action. so,please give me some idea or suggestion on that. i have used it for logoff but on log entry is made when i logoff the system protected override void OnSessionChange(SessionChangeDescription changeDescription) { this.RequestAdditionalTime(250000); //gives a 25 second delay on Logoff if (changeDescription.Reason == SessionChangeReason.SessionLogoff) { // Add your save code here StreamWriter str = new StreamWriter("D:\\Log.txt", true); str.WriteLine("Service stoped due to " + changeDescription.Reason.ToString() + "on" + DateTime.Now.ToString()); str.Close(); } base.OnSessionChange(changeDescription); }

Main.py import wx import wx.lib.mixins.listctrl as listmix from database import * import sys class DataWindow(wx.Frame): def __init__(self, parent = None): wx.Frame.__init__(self, parent, -1, 'DataList', size=(640,480)) self.win = DataList(self) self.Center() self.Show(True) class DataList(wx.ListCtrl, listmix.ListCtrlAutoWidthMixin, listmix.ColumnSorterMixin): def __init__(self, parent = DataWindow): wx.ListCtrl.__init__( self, parent, -1, style=wx.LC_REPORT|wx.LC_VIRTUAL|wx.LC_HRULES|wx.LC_VRULES) #building the columns self.InsertColumn(0, "Location") self.InsertColumn(1, "Address") self.InsertColumn(2, "Subnet") self.InsertColumn(3, "Gateway") self.SetColumnWidth(0, 100) self.SetColumnWidth(1, 150) self.SetColumnWidth(2, 150) self.SetColumnWidth(3, 150) class MainWindow(wx.Frame): def __init__(self, parent = None, id = -1, title = "MainWindow"): wx.Frame.__init__(self, parent, id, title, size = (800,600), style = wx.DEFAULT_FRAME_STYLE ^ (wx.RESIZE_BORDER)) # StatusBar self.CreateStatusBar() # Filemenu filemenu = wx.Menu() # Filemenu - About menuitem = filemenu.Append(-1, "&About", "Information about this application") self.Bind(wx.EVT_MENU, self.onAbout, menuitem) #Filemenu - Data menuitem = filemenu.Append(-1, "&Data", "Get data") self.Bind(wx.EVT_MENU, self.onData, menuitem) # Filemenu - Seperator filemenu.AppendSeparator() #Filemenu - Exit menuitem = filemenu.Append(-1, "&Exit", "Exit the application") self.Bind(wx.EVT_MENU, self.onExit, menuitem) # Menubar menubar = wx.MenuBar() menubar.Append(filemenu, "&File") self.SetMenuBar(menubar) # Show self.Show(True) self.Center() def onAbout(self, event): pass def onData(self, event): DataWindow(self) callDb = Database() sql = "SELECT rowid, address, subnet, gateway FROM pod1" records = callDb.select(sql) for v in records: print "How do I get the records on the DataList?" #print "%s%s%s" % (v[1],v[2],v[3]) #for v in records: #DataList.InsertStringItem("%s") % (v[0], v[1], v[2]) def onExit(self, event): self.Close() self.Destroy() def onSave(self, event): pass if __name__ == '__main__': app = wx.App() frame = MainWindow(None, -1) frame.Show() app.MainLoop() database.py import os import sqlite3 class Database(object): def __init__(self, db_file="data/data.sqlite"): database_allready_exists = os.path.exists(db_file) self.db = sqlite3.connect(db_file) if not database_allready_exists: self.setupDefaultData() def select(self,sql): cursor = self.db.cursor() cursor.execute(sql) records = cursor.fetchall() cursor.close return records def insert(self,sql): newID = 0 cursor = self.db.cursor() cursor.execute(sql) newID = cursor.lastrowid self.db.commit() cursor.close() return newID def save(self,sql): cursor = self.db.cursor() cursor.execute(sql) self.db.commit() cursor.close() def setupDefaultData(self): pass

  • TicTacToe strategic reduction

    - by NickLarsen
    I decided to write a small program that solves TicTacToe in order to try out the effect of some pruning techniques on a trivial game. The full game tree using minimax to solve it only ends up with 549,946 possible games. With alpha-beta pruning, the number of states required to evaluate was reduced to 18,297. Then I applied a transposition table that brings the number down to 2,592. Now I want to see how low that number can go. The next enhancement I want to apply is a strategic reduction. The basic idea is to combine states that have equivalent strategic value. For instance, on the first move, if X plays first, there is nothing strategically different (assuming your opponent plays optimally) about choosing one corner instead of another. In the same situation, the same is true of the center of the walls of the board, and the center is also significant. By reducing to significant states only, you end up with only 3 states for evaluation on the first move instead of 9. This technique should be very useful since it prunes states near the top of the game tree. This idea came from the GameShrink method created by a group at CMU, only I am trying to avoid writing the general form, and just doing what is needed to apply the technique to TicTacToe. In order to achieve this, I modified my hash function (for the transposition table) to enumerate all strategically equivalent positions (using rotation and flipping functions), and to only return the lowest of the values for each board. Unfortunately now my program thinks X can force a win in 5 moves from an empty board when going first. After a long debugging session, it became apparent to me the program was always returning the move for the lowest strategically significant move (I store the last move in the transposition table as part of my state). Is there a better way I can go about adding this feature, or a simple method for determining the correct move applicable to the current situation with what I have already done?

  • Update on: How to model random non-overlapping spheres of non-uniform size in a cube using Matlab?

    - by user3838079
    I am trying to use MATLAB for generating random locations for non-uniform size spheres (non-overlapping) in a cube. The for loop in the code below never seems to end. I don't know what am missing in the code. I have ran the code for no. of spheres (n) = 10; dims = [ 10 10 10 ] function [ c r ] = randomSphere( dims ) % creating one sphere at random inside [0..dims(1)]x[0..dims(2)]x... % radius and center coordinates are sampled from a uniform distribution % over the relevant domain. % output: c - center of sphere (vector cx, cy,... ) % r - radius of sphere (scalar) r = rand(1); % you might want to scale this w.r.t dims or other consideration c = r + rand( size(dims) )./( dims - 2*r ); % make sure sphere does not exceed boundaries function ovlp = nonOverlapping( centers, rads ) % check if several spheres with centers and rads overlap or not ovlp = false; if numel( rads ) == 1 return; % nothing to check for a single sphere end dst = sqrt( sum( bsxfun( @minus, permute( centers, [1 3 2] ),... permute( centers, [3 1 2] ) ).^2, 3) ); ovlp = dst >= bsxfun( @plus, rads, rads.' ); %' all distances must be smaller than r1+r2 ovlp = any( ovlp(:) ); % all must not overlap function [centers rads] = sampleSpheres( dims, n ) % dims is assumed to be a row vector of size 1-by-ndim % preallocate ndim = numel(dims); centers = zeros( n, ndim ); rads = zeros( n, 1 ); ii = 1; while ii <= n [centers(ii,:), rads(ii) ] = randomSphere( dims ); if nonOverlapping( centers(1:ii,:), rads(1:ii) ) ii = ii + 1; % accept and move on end end

  • NoSQL for filesystem storage organization and replication?

    - by wheaties
    We've been discussing design of a data warehouse strategy within our group for meeting testing, reproducibility, and data syncing requirements. One of the suggested ideas is to adapt a NoSQL approach using an existing tool rather than try to re-implement a whole lot of the same on a file system. I don't know if a NoSQL approach is even the best approach to what we're trying to accomplish but perhaps if I describe what we need/want you all can help. Most of our files are large, 50+ Gig in size, held in a proprietary, third-party format. We need to be able to access each file by a name/date/source/time/artifact combination. Essentially a key-value pair style look-up. When we query for a file, we don't want to have to load all of it into memory. They're really too large and would swamp our server. We want to be able to somehow get a reference to the file and then use a proprietary, third-party API to ingest portions of it. We want to easily add, remove, and export files from storage. We'd like to set up automatic file replication between two servers (we can write a script for this.) That is, sync the contents of one server with another. We don't need a distributed system where it only appears as if we have one server. We'd like complete replication. We also have other smaller files that have a tree type relationship with the Big files. One file's content will point to the next and so on, and so on. It's not a "spoked wheel," it's a full blown tree. We'd prefer a Python, C or C++ API to work with a system like this but most of us are experienced with a variety of languages. We don't mind as long as it works, gets the job done, and saves us time. What you think? Is there something out there like this?
