  • C# Windows Service XML

    - by Goober
    Scenario I have a windows service written in C# that performs some processing based on parsing an XML file and use that data to carry out various tasks. The service also does various bits of logging - which uses settings from an APP.Config file. The Problem When the service is compiled, installed and run, the XML file seems to disappear. I'm getting the impression that it is just ignored or something like that. So far I've tried using TWO App.Config files, one named App.Config that contains settings for the service, and the other called MyService.exe.config that contains all of the data that was used in the XML file (the idea being that I can parse the XML from a config file that actually gets compiled and appears in my installation directory. However When I do this, all that happens is that ONE config file appears (with the name MyService.exe.config), but it contains the contents of the App.Config file and not the XML data that I want to parse. What I need All I want is to have a config file for my settings, and an XML file for my data. Question Is this possible? I know the application works as it was originally built as a console application that ran fine. Other The application has to be designed this way (as in, I need my data stored as XML, and my settings stored in a config file). Thoughts If I could somehow combine the contents of the two files into ONE config file, that would be one way of solving the problem. However, I have tried this and of course I get a "Type Initialisation Exception", as the config file cannot interprate the XML data (probably because the tags are custom and do not form any part of the config schema - or something like that). Ideas Please could someone explain to me if it is possible for me to have an XML file AND a config file that will actually be compiled and stored in my installation directory for the service when it is run? CODE Custom XML/Data Config File <?xml version="1.0" encoding="utf-8" ?> <configuration> <servers> <SV066930> <add name="Name" value = "SV066930" /> <processes> <SimonTest1> <add name="ProcessName" value="notepad.exe" /> <add name="CommandLine" value="C:\\WINDOWS\\system32\\notepad.exe C:\\WINDOWS\\Profiles\\TA2TOF1\\Desktop\\SimonTest1.txt" /> </SimonTest1> </processes> </SV066930> </servers> </configuration> APP.Config Settings File <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxx" /> </configSections> <connectionStrings> <add name="DB" connectionString="Data Source=etc......" /> </connectionStrings> </configuration> Help greatly appreciated.

  • Asp.Net Export to Excel - Japanese Characters

    - by Kalyan
    I am currently using Visual Studio 2008 for my ASP .NET application. I am trying to Export some reports with Japanese Characters to Excel via the Response object. When I try to Export, all the Japanese characters looks garbled. It works fine with Chinese Characters. Here is what I tried: I tried Installed Japanese Language Pack / Encoding to UTF-8 / UTF-7 / Shift-JIS / Globalization (Web.Config) .. but no luck. Any Ideas how this can be fixed ? Thanks !! string attachment = "attachment; filename=PerksPlusReport.xls"; //Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("content-disposition", attachment); //Response.Charset = "UTF-8"; //Response.Charset = "UTF-7"; //Response.Charset = "Shift_JIS"; Response.ContentType = "application/vnd.ms-excel"; StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); // Create a form to contain the grid HtmlForm frm = new HtmlForm(); ReportGridView.Parent.Controls.Add(frm); frm.Attributes["runat"] = "server"; GridView GridView2 = new GridView(); ReportView reportDetails = GetReportDetails(); GridView2.DataSource = GetReportResults(this.ReportId.Value, reportDetails.Sql); GridView2.DataBind(); PrepareGridViewForExport(GridView2); frm.Controls.Add(GridView2); frm.RenderControl(htw); string fileContents = sw.ToString(); int startSpot = fileContents.IndexOf("<table"); fileContents = fileContents.Substring(startSpot); int endSpot = fileContents.IndexOf("</table>"); fileContents = fileContents.Substring(0, endSpot + 8); try { // Replace all &lt; and &gt; with < and > fileContents = fileContents.Replace("&lt;", "<"); fileContents = fileContents.Replace("&gt;", ">"); fileContents = fileContents.Replace("€", "&euro;"); string RegularExpression = @"<a[^>]*>([^<]*)</a>"; Regex regex = new Regex(RegularExpression); //If match found .. uses the delegate function to replace the whole content with the filtered values if (regex.IsMatch(fileContents)) { regex.Replace(fileContents, delegate (Match m){return fileContents.Replace(m.Captures[0].Value, m.Groups[1].Value);}); } } catch (Exception ex2) { Response.Write(ex2.ToString()); } Response.Write(fileContents); Response.End();

  • "Row not found or changed" Problem

    - by winston schröder
    Hi there, I'm working on a SQL CE Database and get into the "Row nor found or changed" exception. The exception only occurs when I try to update. On the first Run after the insert it shows up a MemberChangeConflict which says, that my Column Created_at has in all three values (current, original, database) the same. But in a second attempt it doesn't appear anymore. The DataContext is instanciated on Startup and freed on Exit of my Local(!) Application. I use a sqlmetal generated mapping and code file. In the map I added some Associations and set the timemstamp columns UpdateCheck property to Always while all other have the setting never. The Timestamp Column is marked as isVersion="true", the Id Column as Primary Key. Since I don't dispose the datacontext I expected to be using implicit transaction. When I run the SubmitChanges Method within a TransactionScope. Can anyone tell me how I can update the timestamp within the code ? I know about the Problems one has to deal with if you dispose the datacontext. So I decided not to do this since I use a Single User Local DB Cache File. (I did already use a version where I disposed the datacontext after every usage, but this version had a real bad performance and error rate, so I decided to choose the other variant.) LibDB.Client.Vehicles tmp = null; try { tmp = e.Parameter as LibDB.Client.Vehicles; if (tmp == null) return; if (!this._dc.Vehicles.Contains(tmp)) { this._dc.Vehicles.Attach(tmp); } this.ShowChangesReport(this._dc.GetChangeSet()); using (TransactionScope ts = new TransactionScope()) { try { this._dc.SubmitChanges(); ts.Complete(); } catch (ChangeConflictException cce) { Console.WriteLine("Optimistic concurrency error."); Console.WriteLine(cce.Message); Console.ReadLine(); foreach (ObjectChangeConflict occ in this._dc.ChangeConflicts) { MetaTable metatable = this._dc.Mapping.GetTable(occ.Object.GetType()); LibDB.Client.Vehicles entityInConflict = (LibDB.Client.Vehicles)occ.Object; Console.WriteLine("Table name: {0}", metatable.TableName); Console.Write("Vin: "); Console.WriteLine(entityInConflict.Vin); foreach (MemberChangeConflict mcc in occ.MemberConflicts) { object currVal = mcc.CurrentValue; object origVal = mcc.OriginalValue; object databaseVal = mcc.DatabaseValue; MemberInfo mi = mcc.Member; Console.WriteLine("Member: {0}", mi.Name); Console.WriteLine("current value: {0}", currVal); Console.WriteLine("original value: {0}", origVal); Console.WriteLine("database value: {0}", databaseVal); } throw cce; } } catch (Exception ex) { this.ShowChangeConflicts(this._dc.ChangeConflicts); Console.WriteLine(ex.Message); } } this.ShowChangesReport(this._dc.GetChangeSet());

  • Jasper report always showing no content, why?

    - by spderosso
    Hi, I have the following code: InputStream reportFile = MyPage.this.getClass().getResourceAsStream("test.jrxml"); HashMap<String, String> parameters = new HashMap<String, String>(); parameters.put("StringParameterName", "show me"); try { JasperReport report = JasperCompileManager.compileReport(reportFile); JasperPrint print = JasperFillManager.fillReport(report, parameters); return JasperExportManager.exportReportToPdf(print); } catch (JRException e) { // TODO Auto-generated catch block e.printStackTrace(); return null; } And the test.jrxml looks like this (I generated part of it with the iReport, the only thing I did was to remove the language="groovy" attribute): <?xml version="1.0" encoding="UTF-8"?> <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="test" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <parameter name="StringParameterName" isForPrompting="false" class="java.lang.String"/> <background> <band splitType="Stretch"/> </background> <title> <band height="20"> <staticText> <reportElement x="180" y="0" width="200" height="20"/> <text><![CDATA[Hello World!]]></text> </staticText> </band> </title> <pageHeader> <band height="35" splitType="Stretch"/> </pageHeader> <columnHeader> <band height="61" splitType="Stretch"/> </columnHeader> <detail> <band height="125" splitType="Stretch"> <textField> <reportElement x="243" y="77" width="100" height="20"/> <textElement/> <textFieldExpression class="java.lang.String"><![CDATA[$P{StringParameterName}]]></textFieldExpression> </textField> </band> </detail> <columnFooter> <band height="45" splitType="Stretch"/> </columnFooter> <pageFooter> <band height="54" splitType="Stretch"/> </pageFooter> <summary> <band height="42" splitType="Stretch"/> </summary> </jasperReport> As a result I always get a blank pdf file.

  • Compress file to bytes for uploading to SQL Server

    - by Chris
    I am trying to zip files to an SQL Server database table. I can't ensure that the user of the tool has write priveledges on the source file folder so I want to load the file into memory, compress it to an array of bytes and insert it into my database. This below does not work. class ZipFileToSql { public event MessageHandler Message; protected virtual void OnMessage(string msg) { if (Message != null) { MessageHandlerEventArgs args = new MessageHandlerEventArgs(); args.Message = msg; Message(this, args); } } private int sourceFileId; private SqlConnection Conn; private string PathToFile; private bool isExecuting; public bool IsExecuting { get { return isExecuting; } } public int SourceFileId { get { return sourceFileId; } } public ZipFileToSql(string pathToFile, SqlConnection conn) { isExecuting = false; PathToFile = pathToFile; Conn = conn; } public void Execute() { isExecuting = true; byte[] data; byte[] cmpData; //create temp zip file OnMessage("Reading file to memory"); FileStream fs = File.OpenRead(PathToFile); data = new byte[fs.Length]; ReadWholeArray(fs, data); OnMessage("Zipping file to memory"); MemoryStream ms = new MemoryStream(); GZipStream zip = new GZipStream(ms, CompressionMode.Compress, true); zip.Write(data, 0, data.Length); cmpData = new byte[ms.Length]; ReadWholeArray(ms, cmpData); OnMessage("Saving file to database"); using (SqlCommand cmd = Conn.CreateCommand()) { cmd.CommandText = @"MergeFileUploads"; cmd.CommandType = CommandType.StoredProcedure; //cmd.Parameters.Add("@File", SqlDbType.VarBinary).Value = data; cmd.Parameters.Add("@File", SqlDbType.VarBinary).Value = cmpData; SqlParameter p = new SqlParameter(); p.ParameterName = "@SourceFileId"; p.Direction = ParameterDirection.Output; p.SqlDbType = SqlDbType.Int; cmd.Parameters.Add(p); cmd.ExecuteNonQuery(); sourceFileId = (int)p.Value; } OnMessage("File Saved"); isExecuting = false; } private void ReadWholeArray(Stream stream, byte[] data) { int offset = 0; int remaining = data.Length; float Step = data.Length / 100; float NextStep = data.Length - Step; while (remaining > 0) { int read = stream.Read(data, offset, remaining); if (read <= 0) throw new EndOfStreamException (String.Format("End of stream reached with {0} bytes left to read", remaining)); remaining -= read; offset += read; if (remaining < NextStep) { NextStep -= Step; } } } }

  • mySQL to XLS using PHP?

    - by kielie
    Hi guys, how can I create a .XLS document from a mySQL table using PHP? I have tried just about everything, with no success. Basically, I need to take form data, and input it into a database, which I have done, and then I need to retrieve that table data and parse it into a microsoft excel file, which needs to be saved automatically onto the web server. <?php // DB TABLE Exporter // // How to use: // // Place this file in a safe place, edit the info just below here // browse to the file, enjoy! // CHANGE THIS STUFF FOR WHAT YOU NEED TO DO $dbhost = "-"; $dbuser = "-"; $dbpass = "-"; $dbname = "-"; $dbtable = "-"; // END CHANGING STUFF $cdate = date("Y-m-d"); // get current date // first thing that we are going to do is make some functions for writing out // and excel file. These functions do some hex writing and to be honest I got // them from some where else but hey it works so I am not going to question it // just reuse // This one makes the beginning of the xls file function xlsBOF() { echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0); return; } // This one makes the end of the xls file function xlsEOF() { echo pack("ss", 0x0A, 0x00); return; } // this will write text in the cell you specify function xlsWriteLabel($Row, $Col, $Value ) { $L = strlen($Value); echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L); echo $Value; return; } // make the connection an DB query $dbc = mysql_connect( $dbhost , $dbuser , $dbpass ) or die( mysql_error() ); mysql_select_db( $dbname ); $q = "SELECT * FROM ".$dbtable."

I need to get this working quite urgently, so any help would be greatly appreciated. Thanx guys.

  • Saving a .xls file with fwrite

    - by kielie
    hi guys, I have to create a script that takes a mySQL table, and exports it into .XSL format, and then saves that file into a specified folder on the web host. I got it working, but now I can't seem to get it to automatically save the file to the location without prompting the user. It needs to run every day at a specified time, so it can save the previous days leads into a .XSL file on the web host. Here is the code: <?php // DB TABLE Exporter // // How to use: // // Place this file in a safe place, edit the info just below here // browse to the file, enjoy! // CHANGE THIS STUFF FOR WHAT YOU NEED TO DO $dbhost = "-"; $dbuser = "-"; $dbpass = "-"; $dbname = "-"; $dbtable = "-"; // END CHANGING STUFF $cdate = date("Y-m-d"); // get current date // first thing that we are going to do is make some functions for writing out // and excel file.

Here is the original code, as I found it, any help would be greatly appreciated. :-) Thanx in advance. :-)

  • RegEx to ignore / skip everything in html tags

    - by Scott Sumpter
    Looking for a way to combine two Regular Expressions. One to catch the urls and the other to ensure is skips text within html tags. See sample text below functions. Need to pass a block of news text and format text by wrapping urls and email addresses in html tags so users don't have to. The below code works great until there are already html tags within the text. In that case it doubles the html tags. There are plenty of examples to strip html, but I want to just ignore it since the url is already linkified. Also - if there is an easier was to accomplish this, with or without Regex, please let me know. none of my attempts to combine Regexs have worked. coding in ASP.NET VB but will take any workable example/direction. Thanks! ===== Functions ============= Public Shared Function InsertHyperlinks(ByVal inText As String) As String Dim strBuf As String Dim objMatches As Object Dim iStart, iEnd As Integer strBuf = "" iStart = 1 iEnd = 1 Dim strRegUrlEmail As String = "\b(www|http|\S+@)\S+\b" 'RegEx to find urls and email addresses Dim objRegExp As New Regex(strRegUrlEmail, RegexOptions.IgnoreCase) 'Match URLs and emails Dim MatchList As MatchCollection = objRegExp.Matches(inText) If MatchList.Count <> 0 Then objMatches = objRegExp.Matches(inText) For Each Match In MatchList iEnd = Match.Index strBuf = strBuf & Mid(inText, iStart, iEnd - iStart + 1) If InStr(1, Match.Value, "@") Then strBuf = strBuf & HrefGet(Match.Value, "EMAIL", "_BLANK") Else strBuf = strBuf & HrefGet(Match.Value, "WEB", "_BLANK") End If iStart = iEnd + Match.Length + 1 Next strBuf = strBuf & Mid(inText, iStart) InsertHyperlinks = strBuf Else 'No hyperlinks to replace InsertHyperlinks = inText End If End Function Shared Function HrefGet(ByVal url As String, ByVal urlType As String, ByVal Target As String) As String Dim strBuf As String strBuf = "<a href=""" If UCase(urlType) = "WEB" Then If LCase(Left(url, 3)) = "www" Then strBuf = "<a href=""http://" & url & """ Target=""" & _ Target & """>" & url & "</a>" Else strBuf = "<a href=""" & url & """ Target=""" & _ Target & """>" & url & "</a>" End If ElseIf UCase(urlType) = "EMAIL" Then strBuf = "<a href=""mailto:" & url & """ Target=""" & _ Target & """>" & url & "</a>" End If HrefGet = strBuf End Function ===== Sample Text ============= This would be the inText parameter.

Example Screen Window1.xaml: <Window.Resources> <Style TargetType="{x:Type ListViewItem}"> <Style.Triggers> <DataTrigger Binding="{Binding Path=BoolFlag}" Value="True"> <Setter Property="Background" Value="LightGreen" /> </DataTrigger> </Style.Triggers> </Style> </Window.Resources> <StackPanel> <ListView ItemsSource="{Binding Path=Personen}" SelectionMode="Single" SelectionChanged="ListViewSelectionChanged"> <ListView.View> <GridView> <GridViewColumn DisplayMemberBinding="{Binding Path=Vorname}" Header="Vorname" /> <GridViewColumn DisplayMemberBinding="{Binding Path=Nachname}" Header="Nachname" /> <GridViewColumn DisplayMemberBinding="{Binding Path=Alter}" Header="Alter" /> <GridViewColumn DisplayMemberBinding="{Binding Path=BoolFlag}" Header="BoolFlag" /> </GridView> </ListView.View> </ListView> </StackPanel> Window1.xaml.cs: public partial class Window1 : Window { private IList<Person> _personen = new List<Person>(); public Window1() { _personen.Add(new Person { Vorname = "Max", Nachname = "Mustermann", Alter = 18, BoolFlag = false, }); _personen.Add(new Person { Vorname = "Karl", Nachname = "Mayer", Alter = 27, BoolFlag = true, }); _personen.Add(new Person { Vorname = "Josef", Nachname = "Huber", Alter = 38, BoolFlag = false, }); DataContext = this; InitializeComponent(); } public IList<Person> Personen { get { return _personen; } } private void ListViewSelectionChanged(object sender, SelectionChangedEventArgs e) { Person person = e.AddedItems[0] as Person; if (person != null) { if (person.BoolFlag) { this.Resources[SystemColors.HighlightBrushKey] = Brushes.Green; } else { this.Resources[SystemColors.HighlightBrushKey] = Brushes.RoyalBlue; } } } } Person.cs: public class Person { public string Vorname { get; set; } public string Nachname { get; set; } public int Alter { get; set; } public bool BoolFlag { get; set; } } Now I want to set the highlight color of the selected item, depending on the boolflag. In Code-Behind I do this with: private void ListViewSelectionChanged(object sender, SelectionChangedEventArgs e) { Person person = e.AddedItems[0] as Person; if (person != null) { if (person.BoolFlag) { this.Resources[SystemColors.HighlightBrushKey] = Brushes.Green; } else { this.Resources[SystemColors.HighlightBrushKey] = Brushes.RoyalBlue; } } } } This works fine, but now I want to define the code above in the XAML-file. With <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Green" /> I can overwrite the default-value. However, it works, but the color is set to Green for all selected items. I have tried different ways to switch the color of HighlightBrushKey between Green and Blue in XAML, depending on the boolflag, but I didn't succeed. May you can help me and give me some examples?

  • Binding a property to change the listbox items foreground individually for each item

    - by Eyal-Shilony
    I'm trying to change the foreground color of the items in the ListBox individually for each item, I've already posted a similar question but this one is more concrete. I hoped that the state of the color is reserved for each item added to the ListBox, so I tried to create a property (in this case "HotkeysForeground"), bind it and change the color when the items are added in the "HotkeyManager_NewHotkey" event, the problem it's changing the foreground color for all the items in the ListBox. How can I do that per item ? Here is the ViewModel I use. namespace Monkey.Core.ViewModel { using System; using System.Collections.ObjectModel; using System.Windows.Media; using Monkey.Core.SystemMonitor.Accessibility; using Monkey.Core.SystemMonitor.Input; public class MainWindowViewModel : WorkspaceViewModel { private readonly FocusManager _focusManager; private readonly HotkeyManager _hotkeyManager; private readonly ObservableCollection<string> _hotkeys; private Color _foregroundColor; private string _title; public MainWindowViewModel() { _hotkeys = new ObservableCollection<string>(); _hotkeyManager = new HotkeyManager(); _hotkeyManager.NewHotkey += HotkeyManager_NewHotkey; _focusManager = new FocusManager(); _focusManager.Focus += FocusManager_Focus; } public Color HotkeysForeground { get { return _foregroundColor; } set { _foregroundColor = value; OnPropertyChanged(() => HotkeysForeground); } } public ReadOnlyObservableCollection<string> Hotkeys { get { return new ReadOnlyObservableCollection<string>(_hotkeys); } } public string Title { get { return _title; } set { _title = value; OnPropertyChanged(() => Title); } } protected override void OnDispose() { base.OnDispose(); _hotkeyManager.Dispose(); _focusManager.Dispose(); } private void FocusManager_Focus(object sender, FocusManagerEventArgs e) { Title = e.Title; } private void HotkeyManager_NewHotkey(object sender, EventArgs eventArgs) { HotkeysForeground = _hotkeys.Count <= 2 ? Colors.Blue : Colors.Brown; _hotkeys.Clear(); foreach (var hotkey in _hotkeyManager.GetHotkeys()) { _hotkeys.Add(hotkey); } } } } Here is the view. <Window x:Class="Monkey.View.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:System="clr-namespace:System;assembly=mscorlib" Title="{Binding Mode=OneWay, Path=Title, UpdateSourceTrigger=PropertyChanged}" Height="200" Width="200" ShowInTaskbar="False" WindowStyle="ToolWindow" Topmost="True" ResizeMode="CanResizeWithGrip" AllowsTransparency="False"> <Window.Resources> <SolidColorBrush Color="{Binding HotkeysForeground}" x:Key="HotkeysBrush"/> </Window.Resources> <ListBox Canvas.Left="110" Canvas.Top="74" Name="HotkeyList" Height="Auto" Width="Auto" HorizontalContentAlignment="Left" BorderThickness="0" ScrollViewer.CanContentScroll="False" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Disabled" ItemsSource="{Binding Path=Hotkeys}" VerticalAlignment="Stretch" VerticalContentAlignment="Center" FontSize="20"> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="IsEnabled" Value="False" /> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <Label Content="{Binding}" Foreground="{StaticResource HotkeysBrush}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Window> Thank you in advance.

  • Why isn't my algorithm for find the biggest and smallest inputs working?

    - by Matt Ellen
    I have started a new job, and with it comes a new language: Ironpython. Thankfully a good language :D Before starting I got to grips with Python on the whole, but that was only a week's worth of learning. Now I'm writing actual code. I've been charged with writing an algorithm that finds the best input parameter to collect data with. The basic algorithm is (as I've been instructed): Set the input parameter to a good guess Start collecting data When data is available stop collecting find the highest point If the point before this (i.e. for the previous parameter value) was higher and the point before that was lower then we've found the max otherwise the input parameter is increased by the initial guess. goto 2 If the max is found then the min needs to be found. To do this the algorithm carries on increasing the input, but by 1/10 of the max, until the current point is greater than the previous point and the point before that is also greater. Once the min is found then the algorithm stops. Currently I have a simplified data generator outputting the sin of the input, so that I know that the min value should be PI and the max value should be PI/2 The main Python code looks like this (don't worry, this is just for my edification, I don't write real code like this): import sys sys.path.append(r"F:\Programming Source\C#\PythonHelp\PythonHelp\bin\Debug") import clr clr.AddReferenceToFile("PythonHelpClasses.dll") import PythonHelpClasses from PHCStruct import Helper from System import Math helper = Helper() def run(): b = PythonHelpClasses.Executor() a = PythonHelpClasses.HasAnEvent() b.Input = 0.0 helper.__init__() def AnEventHandler(e): b.Stop() h = helper h.lastLastVal, h.lastVal, h.currentVal = h.lastVal, h.currentVal, e.Number if h.lastLastVal < h.lastVal and h.currentVal < h.lastVal and h.NotPast90: h.NotPast90 = False h.bestInput = h.lastInput inputInc = 0.0 if h.NotPast90: inputInc = Math.PI/10.0 else: inputInc = h.bestInput/10.0 if h.lastLastVal > h.lastVal and h.currentVal > h.lastVal and h.NotPast180: h.NotPast180 = False if h.NotPast180: h.lastInput, b.Input = b.Input, b.Input + inputInc b.Start(a) else: print "Best input:", h.bestInput print "Last input:", h.lastInput b.Stop() a.AnEvent += AnEventHandler b.Start(a) PHCStruct.py: class Helper(): def __init__(self): self.currentVal = 0 self.lastVal = 0 self.lastLastVal = 0 self.NotPast90 = True self.NotPast180 = True self.bestInput = 0 self.lastInput = 0 PythonHelpClasses has two small classes I wrote in C# before I realised how to do it in Ironpython. Executor runs a delegate asynchronously while it's running member is true. The important code: public void Start(HasAnEvent hae) { running = true; RunDelegate r = new RunDelegate(hae.UpdateNumber); AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar = r.BeginInvoke(Input, ac, null); } public void Stop() { running = false; } public void UpdateDone(IAsyncResult ar) { RunDelegate r = (RunDelegate)((AsyncResult)ar).AsyncDelegate; r.EndInvoke(ar); if (running) { AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar2 = r.BeginInvoke(Input, ac, null); } } HasAnEvent has a function that generates the sin of its input and fires an event with that result as its argument. i.e.: public void UpdateNumber(double val) { AnEventArgs e = new AnEventArgs(Math.Sin(val)); System.Threading.Thread.Sleep(1000); if (null != AnEvent) { AnEvent(e); } } The sleep is in there just to slow things down a bit. The problem I am getting is that the algorithm is not coming up with the best input being PI/2 and the final input being PI, but I can't see why. Also the best and final inputs are different each time I run the programme. Can anyone see why? Also when the algorithm terminates the best and final inputs are printed to the screen multiple times, not just once. Can someone explain why?

  • MIME "Content-Type" folding and parameter question regarding RFCs?

    - by BastiBense
    Hello, I'm trying to implement a basic MIME parser for the multipart/related in C++/Qt. So far I've been writing some basic parser code for headers, and I'm reading the RFCs to get an idea how to do everything as close to the specification as possible. Unfortunately there is a part in the RFC that confuses me a bit: From RFC882 Section 3.1.1: Each header field can be viewed as a single, logical line of ASCII characters, comprising a field-name and a field-body. For convenience, the field-body portion of this conceptual entity can be split into a multiple-line representation; this is called "folding". The general rule is that wherever there may be linear-white-space (NOT simply LWSP-chars), a CRLF immediately followed by AT LEAST one LWSP-char may instead be inserted. Thus, the single line Alright, so I simply parse a header field and if a CRLF follows with linear whitespace, I simply concat those in a useful manner to result in a single header line. Let's proceed... From RFC2045 Section 5.1: In the Augmented BNF notation of RFC 822, a Content-Type header field value is defined as follows: content := "Content-Type" ":" type "/" subtype *(";" parameter) ; Matching of media type and subtype ; is ALWAYS case-insensitive. [...] parameter := attribute "=" value attribute := token ; Matching of attributes ; is ALWAYS case-insensitive. value := token / quoted-string token := 1*<any (US-ASCII) CHAR except SPACE, CTLs, or tspecials> Okay. So it seems if you want to specify a Content-Type header with parameters, simple do it like this: Content-Type: multipart/related; foo=bar; something=else ... and a folded version of the same header would look like this: Content-Type: multipart/related; foo=bar; something=else Correct? Good. As I kept reading the RFCs, I came across the following in RFC2387 Section 5.1 (Examples): Content-Type: Multipart/Related; boundary=example-1 start="<[email protected]>"; type="Application/X-FixedRecord" start-info="-o ps" --example-1 Content-Type: Application/X-FixedRecord Content-ID: <[email protected]> [data] --example-1 Content-Type: Application/octet-stream Content-Description: The fixed length records Content-Transfer-Encoding: base64 Content-ID: <[email protected]> [data] --example-1-- Hmm, this is odd. Do you see the Content-Type header? It has a number of parameters, but not all have a ";" as parameter delimiter. Maybe I just didn't read the RFCs correctly, but if my parser works strictly like the specification defines, the type and start-info parameters would result in a single string or worse, a parser error. Guys, what's your thought on this? Just a typo in the RFCs? Or did I miss something? Thanks!

  • Injection of an EJB into a web java class under JBoss 7.1.1

    - by Dobbo
    I am trying to build a website using JBoss 7.1.1 and RESTeasy. I have managed to constructed and deploy and EAR with a both a WAR and an EJB-JAR contained within: voyager-app.ear META-INF/MANIFEST.MF META-INF/application.xml META-INF/jboss-app.xml lib/voyager-lib.jar voyager-adm.war voyager-ejb.jar voyager-web.war So far things are very simple. voyager-adm.war & voyager-lib.jar are empty (just the manifest file) but I know that I'm going to have code for them shortly. There is just one Stateful EJB - HarbourMasterBean (with just a local interface) and a few Database Entity Beans in the EJB jar file: voyager-ejb.jar META-INF/MANIFEST.MF META-INF/persistence.xml com/nutrastat/voyager/db/HarbourMasterBean.class com/nutrastat/voyager/db/HarbourMasterLocal.class com/nutrastat/voyager/db/PortEntity.class com/nutrastat/voyager/db/ShipEntity.class As far as I can tell the EJBs deploy correctly because the database units are created and the log shows that the publication of some HarbourMaster references: java:global/voyager-app/voyager-ejb/harbour-master!com.nutrastat.voyager.db.HarbourMasterLocal java:app/voyager-ejb/harbour-master!com.nutrastat.voyager.db.HarbourMasterLocal java:module/harbour-master!com.nutrastat.voyager.db.HarbourMasterLocal java:global/voyager-app/voyager-ejb/harbour-master java:app/voyager-ejb/harbour-master java:module/harbour-master The problem lies in getting the HarbourMaster EJB injected into my web bean. The reference to it is alway NULL no matter what I try. voyager-web.war META-INF/MANIFEST.MF WEB-INF/web.xml WEB-INF/classes/com/nutrastat/voyager/web/ WEB-INF/classes/com/nutrastat/voyager/web/Ships.class WEB-INF/classes/com/nutrastat/voyager/web/VoyagerApplication.class Ships.java: @Path("fleet") public class Ships { protected transient final Logger log; @EJB private HarbourMasterLocal harbourMaster; public Ships() { log = LoggerFactory.getLogger(getClass()); } @GET @Path("ships") @Produces({"text/plain"}) public String listShips() { if (log.isDebugEnabled()) log.debug("Harbour master value: " + harbourMaster); return "Harbour Master: " + harbourMaster; } } &lt;web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0" &gt; <display-name>Voyager Web Application</display-name> <listener> <listener-class> org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap </listener-class> </listener> <servlet> <servlet-name>Resteasy</servlet-name> <servlet-class> org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher </servlet-class> <init-param> <param-name> javax.ws.rs.Application </param-name> <param-value> com.nutrastat.voyager.web.VoyagerApplication </param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>Resteasy</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> &lt;/web-app&gt; I have been searching the web for an answer and read a number of places, both on StackOverflow and elsewhere that suggests is can be done, and that the problems lies with configuration. But they post only snippets and I'm never sure if I'm doing things correctly. Many thanks for any help you can provide. Dobbo

  • Dropdown dependent values to be fetch from multiple models using ajax in Yii

    - by newuser
    I searched all the documentation over Yii but not got the answer of it.So I came here finally. I have the following schema Table Schools +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_name | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ Table Students +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_id | int(10) | NO | FK | | | | student_name | varchar(100) | NO | | | | | roll_no | varchar(80) | NO | | | | | class | varchar(20) | NO | | | | | | subjects | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ I have made models and CRUD for the both models.In models my relation is like this In Students.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'School' => array(self::BELONGS_TO,'Schools','school_id'), ); } In Schools.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'student' => array(self::HAS_MANY, 'Students', 'school_id'), ); } Now I made the two models rendered in a single page so that I can enter all the respective fields in a single form. In the _form.php file of Students I have made some change in student_name like this <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php echo $form->dropdownList($model,'student_name', CHtml::listData(Students::model()->findAll(), 'id', 'student_name'), array('empty'=>array('Select'=>'--Select One---'))); ?> <?php echo $form->error($model,'student_name'); ?> Now for this piece of code I got all the student name from the Student model. So my problem is when I am getting the student name from the dropdown list and going to select a student it will also fetch all the respective values of the student to be rendered in the _form.php without click on save button.So that user don't have to put it again manually. I think ajax and json encode will work here but don't know how to make them work here. [Update] Here is StudentsController code public function actionDisCoor() { $model = School::model()->findByPk($_POST['Students']['student_id']); $data=CHtml::listData($data,'id','name'); foreach($data as $value=>$name) { echo CHtml::tag('option',array('value'=>$value),CHtml::encode($name),true); } } Here is _form.php code for Students <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php $List = CHtml::listData(Students::model()->findAll(), 'id', 'student_name'); ?> <?php echo $form->dropdownList($model,'student_name',$List, array('onChange'=>CHtml::ajax(array( 'url' => CController::createUrl('DisCoor'), 'type' => 'POST', 'update'=>'#school_id', )),'style'=>'width:180px;' ) )?> <?php echo $form->error($model,'student_name'); ?> </div> After all that when I saw in firebug I got the error.Here is the screen shot

  • About the MSDN Documentation on NOTIFYICONDATA's cbSize member

    - by KenC
    I am reading the NOTIFYICONDATA documentation in MSDN. It says the NOTIFYICONDATA structure has a cbSize member should be set to the size of the structure, but NOTIFYICONDATA structure's size has different size in every Shell32.dll, so you should get the Shell32.dll version before setting cbSize. The following quotes from MSDN: If it is version 5.0 or later, initialize the cbSize member as follows. nid.cbSize = sizeof(NOTIFYICONDATA); Setting cbSize to this value enables all the version 5.0 and 6.0 enhancements. For earlier versions, the size of the pre-6.0 structure is given by the NOTIFYICONDATA_V2_SIZE constant and the pre-5.0 structure is given by the NOTIFYICONDATA_V1_SIZE constant. Initialize the cbSize member as follows. nid.cbSize = NOTIFYICONDATA_V2_SIZE; Using this value for cbSize will allow your application to use NOTIFYICONDATA with earlier Shell32.dll versions, although without the version 6.0 enhancements. I found it a bit of vague, because 'sizeof(NOTIFYICONDATA)' has different value in Win98 (using Shell32.dll version 4.x), Win2K (version 5.0) and WinXP (version 6.0). How could it 'enable all version 5.0 and 6.0 enhancements'? So I looked for the definition of NOTIFYICONDATA_V1_SIZE (source code as below), I see: NOTIFYICONDATA_V1_SIZE is for Win 2K (doesn't include 2K) NOTIFYICONDATA_V2_SIZE is for Win XP NOTIFYICONDATA_V3_SIZE is for Vista (not sure if I am right) It's completely different from what MSDN says? and none for Win2K? So, I am totally confused right now. How should I set the cbSize member according to Shell32.dll version? //= = = = = = = = ShellAPI.h = = = = = = = = typedef struct _NOTIFYICONDATAA { DWORD cbSize; HWND hWnd; UINT uID; UINT uFlags; UINT uCallbackMessage; HICON hIcon; #if (NTDDI_VERSION < NTDDI_WIN2K) CHAR szTip[64]; #endif #if (NTDDI_VERSION >= NTDDI_WIN2K) CHAR szTip[128]; DWORD dwState; DWORD dwStateMask; CHAR szInfo[256]; union { UINT uTimeout; UINT uVersion; // used with NIM_SETVERSION, values 0, 3 and 4 } DUMMYUNIONNAME; CHAR szInfoTitle[64]; DWORD dwInfoFlags; #endif #if (NTDDI_VERSION >= NTDDI_WINXP) GUID guidItem; #endif #if (NTDDI_VERSION >= NTDDI_VISTA) HICON hBalloonIcon; #endif } NOTIFYICONDATAA, *PNOTIFYICONDATAA; typedef struct _NOTIFYICONDATAW { DWORD cbSize; HWND hWnd; UINT uID; UINT uFlags; UINT uCallbackMessage; HICON hIcon; #if (NTDDI_VERSION < NTDDI_WIN2K) WCHAR szTip[64]; #endif #if (NTDDI_VERSION >= NTDDI_WIN2K) WCHAR szTip[128]; DWORD dwState; DWORD dwStateMask; WCHAR szInfo[256]; union { UINT uTimeout; UINT uVersion; // used with NIM_SETVERSION, values 0, 3 and 4 } DUMMYUNIONNAME; WCHAR szInfoTitle[64]; DWORD dwInfoFlags; #endif #if (NTDDI_VERSION >= NTDDI_WINXP) GUID guidItem; #endif #if (NTDDI_VERSION >= NTDDI_VISTA) HICON hBalloonIcon; #endif } NOTIFYICONDATAW, *PNOTIFYICONDATAW; #define NOTIFYICONDATAA_V1_SIZE FIELD_OFFSET(NOTIFYICONDATAA, szTip[64]) #define NOTIFYICONDATAW_V1_SIZE FIELD_OFFSET(NOTIFYICONDATAW, szTip[64]) #ifdef UNICODE #define NOTIFYICONDATA_V1_SIZE NOTIFYICONDATAW_V1_SIZE #else #define NOTIFYICONDATA_V1_SIZE NOTIFYICONDATAA_V1_SIZE #endif #define NOTIFYICONDATAA_V2_SIZE FIELD_OFFSET(NOTIFYICONDATAA, guidItem) #define NOTIFYICONDATAW_V2_SIZE FIELD_OFFSET(NOTIFYICONDATAW, guidItem) #ifdef UNICODE #define NOTIFYICONDATA_V2_SIZE NOTIFYICONDATAW_V2_SIZE #else #define NOTIFYICONDATA_V2_SIZE NOTIFYICONDATAA_V2_SIZE #endif #define NOTIFYICONDATAA_V3_SIZE FIELD_OFFSET(NOTIFYICONDATAA, hBalloonIcon) #define NOTIFYICONDATAW_V3_SIZE FIELD_OFFSET(NOTIFYICONDATAW, hBalloonIcon) #ifdef UNICODE #define NOTIFYICONDATA_V3_SIZE NOTIFYICONDATAW_V3_SIZE #else #define NOTIFYICONDATA_V3_SIZE NOTIFYICONDATAA_V3_SIZE #endif (Seems like the code doesn't look good on the web site, but it from ShellAPI.h, all the same)

  • Calculus? Need help solving for a time-dependent variable given some other variables.

    - by user451527
    Long story short, I'm making a platform game. I'm not old enough to have taken Calculus yet, so I know not of derivatives or integrals, but I know of them. The desired behavior is for my character to automagically jump when there is a block to either side of him that is above the one he's standing on; for instance, stairs. This way the player can just hold left / right to climb stairs, instead of having to spam the jump key too. The issue is with the way I've implemented jumping; I've decided to go mario-style, and allow the player to hold 'jump' longer to jump higher. To do so, I have a 'jump' variable which is added to the player's Y velocity. The jump variable increases to a set value when the 'jump' key is pressed, and decreases very quickly once the 'jump' key is released, but decreases less quickly so long as you hold the 'jump' key down, thus providing continuous acceleration up as long as you hold 'jump.' This also makes for a nice, flowing jump, rather than a visually jarring, abrupt acceleration. So, in order to account for variable stair height, I want to be able to calculate exactly what value the 'jump' variable should get in order to jump exactly to the height of the stair; preferably no more, no less, though slightly more is permissible. This way the character can jump up steep or shallow flights of stairs without it looking weird or being slow. There are essentially 5 variables in play: h -the height the character needs to jump to reach the stair top<br> j -the jump acceleration variable<br> v -the vertical velocity of the character<br> p -the vertical position of the character<br> d -initial vertical position of the player minus final position<br> Each timestep:<br> j -= 1.5; //the jump variable's deceleration<br> v -= j; //the jump value's influence on vertical speed<br> v *= 0.95; //friction on the vertical speed<br> v += 1; //gravity<br> p += v; //add the vertical speed to the vertical position<br> v-initial is known to be zero<br> v-final is known to be zero<br> p-initial is known<br> p-final is known<br> d is known to be p-initial minus p-final<br> j-final is known to be zero<br> j-initial is unknown<br> Given all of these facts, how can I make an equation that will solve for j? tl;dr How do I Calculus? Much thanks to anyone who's made it this far and decides to plow through this problem.

  • Craziest JavaScript behavior I've ever seen

    - by Dan Ray
    And that's saying something. This is based on the Google Maps sample for Directions in the Maps API v3. <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no"/> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>Google Directions</title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var directionDisplay; var directionsService = new google.maps.DirectionsService(); var map; function initialize() { directionsDisplay = new google.maps.DirectionsRenderer(); var myOptions = { zoom:7, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); directionsDisplay.setMap(map); directionsDisplay.setPanel(document.getElementById("directionsPanel")); } function render() { var start; if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { start = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); }, function() { handleNoGeolocation(browserSupportFlag); }); } else { // Browser doesn't support Geolocation handleNoGeolocation(); } alert("booga booga"); var end = '<?= $_REQUEST['destination'] ?>'; var request = { origin:start, destination:end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(response); } }); } </script> </head> <body style="margin:0px; padding:0px;" onload="initialize()"> <div><div id="map_canvas" style="float:left;width:70%; height:100%"></div> <div id="directionsPanel" style="float:right;width:30%;height 100%"></div> <script type="text/javascript">render();</script> </body> </html> See that "alert('booga booga')" in there? With that in place, this all works fantastic. Comment that out, and var start is undefined when we hit the line to define var request. I discovered this when I removed the alert I put in there to show me the value of var start, and it quit working. If I DO ask it to alert me the value of var start, it tells me it's undefined, BUT it has a valid (and accurate!) value when we define var request a few lines later. I'm suspecting it's a timing issue--like an asynchronous something is having time to complete in the background in the moment it takes me to dismiss the alert. Any thoughts on work-arounds?

  • Serializing WPF DataTemplates and {Binding Expressions} (from PowerShell?)

    - by Jaykul
    Ok, here's the deal: I have code that works in C#, but when I call it from PowerShell, it fails. I can't quite figure it out, but it's something specific to PowerShell. Here's the relevant code calling the library (assuming you've added a reference ahead of time) from C#: public class Test { [STAThread] public static void Main() { Console.WriteLine( PoshWpf.XamlHelper.RoundTripXaml( "<TextBlock Text=\"{Binding FullName}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"/>" ) ); } } Compiled into an executable, that works fine ... but if you call that method from PowerShell, it returns with no {Binding FullName} for the Text! add-type -path .\PoshWpf.dll [PoshWpf.Test]::Main() I've pasted below the entire code for the library, all wrapped up in a PowerShell Add-Type call so you can just compile it by pasting it into PowerShell (you can leave off the first and last lines if you want to paste it into a new console app in Visual Studio. To output (from PowerShell 2) as an executable, just change the -OutputType parameter to ConsoleApplication and the -OutputAssembly to PoshWpf.exe (or something). Thus, you can see that running the SAME CODE from the executable gives you the correct output. But running the two lines as above or manually calling [PoshWpf.XamlHelper]::RoundTripXaml or [PoshWpf.XamlHelper]::ConvertToXaml from PowerShell just doesn't seem to work at all ... HELP?! Add-Type -TypeDefinition @" using System; using System.ComponentModel; using System.Globalization; using System.Linq; using System.Windows; using System.Windows.Data; using System.Windows.Markup; namespace PoshWpf { public class Test { [STAThread] public static void Main() { Console.WriteLine( PoshWpf.XamlHelper.RoundTripXaml( "<TextBlock Text=\"{Binding FullName}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"/>" ) ); } } public class BindingTypeDescriptionProvider : TypeDescriptionProvider { private static readonly TypeDescriptionProvider _DEFAULT_TYPE_PROVIDER = TypeDescriptor.GetProvider(typeof(Binding)); public BindingTypeDescriptionProvider() : base(_DEFAULT_TYPE_PROVIDER) { } public override ICustomTypeDescriptor GetTypeDescriptor(Type objectType, object instance) { ICustomTypeDescriptor defaultDescriptor = base.GetTypeDescriptor(objectType, instance); return instance == null ? defaultDescriptor : new BindingCustomTypeDescriptor(defaultDescriptor); } } public class BindingCustomTypeDescriptor : CustomTypeDescriptor { public BindingCustomTypeDescriptor(ICustomTypeDescriptor parent) : base(parent) { } public override PropertyDescriptorCollection GetProperties(Attribute[] attributes) { PropertyDescriptor pd; var pdc = new PropertyDescriptorCollection(base.GetProperties(attributes).Cast<PropertyDescriptor>().ToArray()); if ((pd = pdc.Find("Source", false)) != null) { pdc.Add(TypeDescriptor.CreateProperty(typeof(Binding), pd, new Attribute[] { new DefaultValueAttribute("null") })); pdc.Remove(pd); } return pdc; } } public class BindingConverter : ExpressionConverter { public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType) { return (destinationType == typeof(MarkupExtension)) ? true : false; } public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType) { if (destinationType == typeof(MarkupExtension)) { var bindingExpression = value as BindingExpression; if (bindingExpression == null) throw new Exception(); return bindingExpression.ParentBinding; } return base.ConvertTo(context, culture, value, destinationType); } } public static class XamlHelper { static XamlHelper() { // this is absolutely vital: TypeDescriptor.AddProvider(new BindingTypeDescriptionProvider(), typeof(Binding)); TypeDescriptor.AddAttributes(typeof(BindingExpression), new Attribute[] { new TypeConverterAttribute(typeof(BindingConverter)) }); } public static string RoundTripXaml(string xaml) { return XamlWriter.Save(XamlReader.Parse(xaml)); } public static string ConvertToXaml(object wpf) { return XamlWriter.Save(wpf); } } } "@ -language CSharpVersion3 -reference PresentationCore, PresentationFramework, WindowsBase -OutputType Library -OutputAssembly PoshWpf.dll Again, you can get an executable by just altering the last line like so: "@ -language CSharpVersion3 -reference PresentationCore, PresentationFramework, WindowsBase -OutputType ConsoleApplication -OutputAssembly PoshWpf.exe

  • opengl 3d texture issue

    - by user1478217
    Hi i'm trying to use a 3d texture in opengl to implement volume rendering. Each voxel has an rgba colour value and is currently rendered as a screen facing quad.(for testing purposes). I just can't seem to get the sampler to give me a colour value in the shader. The quads always end up black. When I change the shader to generate a colour (based on xyz coords) then it works fine. I'm loading the texture with the following code: glGenTextures(1, &tex3D); glBindTexture(GL_TEXTURE_3D, tex3D); unsigned int colours[8]; colours[0] = Colour::AsBytes<unsigned int>(Colour::Blue); colours[1] = Colour::AsBytes<unsigned int>(Colour::Red); colours[2] = Colour::AsBytes<unsigned int>(Colour::Green); colours[3] = Colour::AsBytes<unsigned int>(Colour::Magenta); colours[4] = Colour::AsBytes<unsigned int>(Colour::Cyan); colours[5] = Colour::AsBytes<unsigned int>(Colour::Yellow); colours[6] = Colour::AsBytes<unsigned int>(Colour::White); colours[7] = Colour::AsBytes<unsigned int>(Colour::Black); glTexImage3D(GL_TEXTURE_3D, 0, GL_RGBA, 2, 2, 2, 0, GL_RGBA, GL_UNSIGNED_BYTE, colours); The colours array contains the correct data, i.e. the first four bytes have values 0, 0, 255, 255 for blue. Before rendering I bind the texture to the 2nd texture unit like so: glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_3D, tex3D); And render with the following code: shaders["DVR"]->Use(); shaders["DVR"]->Uniforms["volTex"].SetValue(1); shaders["DVR"]->Uniforms["World"].SetValue(Mat4(vl_one)); shaders["DVR"]->Uniforms["viewProj"].SetValue(cam->GetViewTransform() * cam->GetProjectionMatrix()); QuadDrawer::DrawQuads(8); I have used these classes for setting shader params before and they work fine. The quaddrawer draws eight instanced quads. The vertex shader code looks like this: #version 330 layout(location = 0) in vec2 position; layout(location = 1) in vec2 texCoord; uniform sampler3D volTex; ivec3 size = ivec3(2, 2, 2); uniform mat4 World; uniform mat4 viewProj; smooth out vec4 colour; void main() { vec3 texCoord3D; int num = gl_InstanceID; texCoord3D.x = num % size.x; texCoord3D.y = (num / size.x) % size.y; texCoord3D.z = (num / (size.x * size.y)); texCoord3D /= size; texCoord3D *= 2.0; texCoord3D -= 1.0; colour = texture(volTex, texCoord3D); //colour = vec4(texCoord3D, 1.0); gl_Position = viewProj * World * vec4(texCoord3D, 1.0) + (vec4(position.x, position.y, 0.0, 0.0) * 0.05); } uncommenting the line where I set the colour value equal to the texcoord works fine, and makes the quads coloured. The fragment shader is simply: #version 330 smooth in vec4 colour; out vec4 outColour; void main() { outColour = colour; } So my question is, what am I doing wrong, why is the sampler not getting any colour values from the 3d texture? [EDIT] Figured it out but can't self answer (new user): As soon as I posted this I figured it out, I'll put the answer up to help anyone else (it's not specifically a 3d texture issue, and i've also fallen afoul of it before, D'oh!). I didn't generate mipmaps for the texture, and the default magnification/minification filters weren't set to either GL_LINEAR, or GL_NEAREST. Boom! no textures. Same thing happens with 2d textures.
