• How do I get Visual Studio build process to pass condition to library(external) project

  - by Billy Talented

  I have tried several solutions for this problem. Enough to know I do not know enough about MSBuild to do this elegantly but I feel like there should be a method. I have a set of libraries for working with .net projects. A few of the projects utilize System.Web.Mvc - which recently released Version 2 - and we are looking forward to the upgrade. Currently sites which reference this library reference it directly by the project(csproj) on the developer's computer - not a built version of the library so that changes and source code case easily be viewed when dealing code from this library. This works quite well and would prefer to not have to switch to binary references (but will if this is the only solution). The problem I have is that because of some of the functionality that was added onto the MVC1 based library (view engines, model binders etc) several of the sites reliant on these libraries need to stay on MVC1 until we have full evaluated and tested them on MVC2. I would prefer to not have to fork or have two copies on each dev machine. So what I would like to be able to do is set a property group value in the referencing web application and have this read by the above mentions library with the caviat that when working directly on the library via its containing solution I would like to be able to control this via Configuration Manager by selecting a build type and that property overriding the build behavior of the solution (i.e. 'Debug - MVC1' vs 'Debug -MVC2') - I have this working via: <Choose> <When Condition=" '$(Configuration)|$(Platform)' == 'Release - MVC2|AnyCPU' Or '$(Configuration)|$(Platform)' == 'Debug - MVC2|AnyCPU'"> <ItemGroup> <Reference Include="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> </Reference> <Reference Include="Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\Dependancies\Web\MVC2\Microsoft.Web.Mvc.dll</HintPath> </Reference> </ItemGroup> </When> <Otherwise> <ItemGroup> <Reference Include="System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\Dependancies\Web\MVC\System.Web.Mvc.dll</HintPath> </Reference> </ItemGroup> </Otherwise> The item that I am struggling with is the cross solution issue(solution TheWebsite references this project and needs to control which build property to use) that I have not found a way to work with that I think is a solid solution that enabled the build within visual studio to work as it has to date. Other bits: we are using VS2008, Resharper, TeamCity for CI, SVN for source control.

• Joystick input in Java

  - by typoknig

  Hi all, I am making a 2D game in Java and I want to use a joystick to control the movement of some crosshairs. Right now I have it so the mouse can control those crosshairs. My only criteria for this is that the control for the crosshair must stay in the game window unless a user clicks off into another window. Basically I want my game to capture whatever device is controlling the crosshairs much like a virtual machine captures a mouse. The joystick I am using (Thrustmaster Hotas Cougar) comes with some pretty advanced features, so that may make this easier (or harder). I have tried the solution listed on this page, but I am using a 64bit computer and for some reason it does not like that. I have also tried to use the key emulation feature of my joystick, but with little success. Here is what I have so far, any pointer would be appreciated. Main Class: import java.awt.Color; import java.awt.Cursor; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferStrategy; import java.awt.image.MemoryImageSource; import java.awt.Point; import java.awt.Toolkit; import javax.swing.JFrame; public class Game extends JFrame implements MouseMotionListener{ private int windowWidth = 1280; private int windowHeight = 1024; private Crosshair crosshair; public static void main(String[] args) { new Game(); } public Game() { this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setSize(windowWidth, windowHeight); this.setResizable(false); this.setLocation(0,0); this.setVisible(true); this.createBufferStrategy(2); addMouseMotionListener(this); initGame(); while(true) { long start = System.currentTimeMillis(); gameLoop(); while(System.currentTimeMillis()-start < 5) { //empty while loop } } } private void initGame() { hideCursor(); crosshair = new Crosshair (windowWidth/2, windowHeight/2); } private void gameLoop() { //game logic drawFrame(); } private void drawFrame() { BufferStrategy bf = this.getBufferStrategy(); Graphics g = (Graphics)bf.getDrawGraphics(); try { g = bf.getDrawGraphics(); Color darkBlue = new Color(0x010040); g.setColor(darkBlue); g.fillRect(0, 0, windowWidth, windowHeight); drawCrossHair(g); } finally { g.dispose(); } bf.show(); Toolkit.getDefaultToolkit().sync(); } private void drawCrossHair(Graphics g){ Color yellow = new Color (0xEDFF62); g.setColor(yellow); g.drawOval(crosshair.x, crosshair.y, 40, 40); g.fillArc(crosshair.x + 10, crosshair.y + 21 , 20, 20, -45, -90); g.fillArc(crosshair.x - 1, crosshair.y + 10, 20, 20, -135, -90); g.fillArc(crosshair.x + 10, crosshair.y - 1, 20, 20, -225, -90); g.fillArc(crosshair.x + 21, crosshair.y + 10, 20, 20, -315, -90); } @Override public void mouseDragged(MouseEvent e) { //empty method } @Override public void mouseMoved(MouseEvent e) { crosshair.x = e.getX(); crosshair.y = e.getY(); } private void hideCursor() { int[] pixels = new int[16 * 16]; Image image = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, pixels, 0, 16)); Cursor transparentCursor = Toolkit.getDefaultToolkit().createCustomCursor(image, new Point(0, 0), "invisiblecursor"); getContentPane().setCursor(transparentCursor); } } Another Class: public class Crosshair{ public int x; public int y; public Crosshair(int x, int y) { this.x = x; this.y = y; } }

• Apache FOP - Table top and bottom borders missing pagebreak inside table

  - by Thomas

  I am using Apache FOP to generate a PDF from a XLS FO document. I have created a test XLS FO document that contains a table with collapsed borders that with several tall rows. One of the rows starts on one page and ends on the next and this works as expected. The problem is that the bottom border of the table on the first page is missing and the top border of the table on the second pages is also missing. Below is the sample XLS FO document. <?xml version="1.0" encoding="utf-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <!-- defines the layout master --> <fo:layout-master-set> <fo:simple-page-master master-name="first" page-height="29.7cm" page-width="21cm" margin-top="1cm" margin-bottom="2cm" margin-left="2.5cm" margin-right="2.5cm"> <fo:region-body margin-top="3cm"/> <fo:region-before extent="3cm"/> <fo:region-after extent="1.5cm"/> </fo:simple-page-master> </fo:layout-master-set> <!-- starts actual layout --> <fo:page-sequence master-reference="first"> <fo:title>Sample Doc</fo:title> <fo:flow flow-name="xsl-region-body" font-size="x-small" font="Times New Roman"> <!-- table start --> <fo:table table-layout="fixed" width="100%" border-collapse="collapse"> <fo:table-column column-width="35mm"/> <fo:table-column column-width="100mm"/> <fo:table-column column-width="20mm"/> <fo:table-body> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Columns 2</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 3</fo:block> </fo:table-cell> </fo:table-row> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Row 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Lorem Ipsum is simply dummy text of the printing and typesetting industry.

• View Generated Source (After AJAX/JavaScript) in C#

  - by Michael La Voie

  Is there a way to view the generated source of a web page (the code after all AJAX calls and JavaScript DOM manipulations have taken place) from a C# application without opening up a browser from the code? Viewing the initial page using a WebRequest or WebClient object works ok, but if the page makes extensive use of JavaScript to alter the DOM on page load, then these don't provide an accurate picture of the page. I have tried using Selenium and Watin UI testing frameworks and they work perfectly, supplying the generated source as it appears after all JavaScript manipulations are completed. Unfortunately, they do this by opening up an actual web browser, which is very slow. I've implemented a selenium server which offloads this work to another machine, but there is still a substantial delay. Is there a .Net library that will load and parse a page (like a browser) and spit out the generated code? Clearly, Google and Yahoo aren't opening up browsers for every page they want to spider (of course they may have more resources than me...). Is there such a library or am I out of luck unless I'm willing to dissect the source code of an open source browser? SOLUTION Well, thank you everyone for you're help. I have a working solution that is about 10X faster then Selenium. Woo! Thanks to this old article from beansoftware I was able to use the System.Windows.Forms.WebBrwoswer control to download the page and parse it, then give em the generated source. Even though the control is in Windows.Forms, you can still run it from Asp.Net (which is what I'm doing), just remember to add System.Window.Forms to your project references. There are two notable things about the code. First, the WebBrowser control is called in a new thread. This is because it must run on a single threaded apartment. Second, the GeneratedSource variable is set in two places. This is not due to an intelligent design decision :) I'm still working on it and will update this answer when I'm done. wb_DocumentCompleted() is called multiple times. First when the initial HTML is downloaded, then again when the first round of JavaScript completes. Unfortunately, the site I'm scraping has 3 different loading stages. 1) Load initial HTML 2) Do first round of JavaScript DOM manipulation 3) pause for half a second then do a second round of JS DOM manipulation. For some reason, the second round isn't cause by the wb_DocumentCompleted() function, but it is always caught when wb.ReadyState == Complete. So why not remove it from wb_DocumentCompleted()? I'm still not sure why it isn't caught there and that's where the beadsoftware article recommended putting it. I'm going to keep looking into it. I just wanted to publish this code so anyone who's interested can use it. Enjoy! using System.Threading; using System.Windows.Forms; public class WebProcessor { private string GeneratedSource{ get; set; } private string URL { get; set; } public string GetGeneratedHTML(string url) { URL = url; Thread t = new Thread(new ThreadStart(WebBrowserThread)); t.SetApartmentState(ApartmentState.STA); t.Start(); t.Join(); return GeneratedSource; } private void WebBrowserThread() { WebBrowser wb = new WebBrowser(); wb.Navigate(URL); wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler( wb_DocumentCompleted); while (wb.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); //Added this line, because the final HTML takes a while to show up GeneratedSource= wb.Document.Body.InnerHtml; wb.Dispose(); } private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser wb = (WebBrowser)sender; GeneratedSource= wb.Document.Body.InnerHtml; } }

• Java Fx Data bind not working with File Read

  - by rjha94

  Hi I am using a very simple JavaFx client to upload files. I read the file in chunks of 1 MB (using Byte Buffer) and upload using multi part POST to a PHP script.

• Strategy and AI for the game 'Proximity'

  - by smci

  'Proximity' is a strategy game of territorial domination similar to Othello, Go and Risk. Two players, uses a 10x12 hex grid. Game invented by Brian Cable in 2007. Seems to be a worthy game for discussing a) optimal strategy then b) how to build an AI Strategies are going to be probabilistic or heuristic-based, due to the randomness factor, and the high branching factor (starts out at 120). So it will be kind of hard to compare objectively. A compute time limit of 5s per turn seems reasonable. Game: Flash version here and many copies elsewhere on the web Rules: here Object: to have control of the most armies after all tiles have been placed. Each turn you received a randomly numbered tile (value between 1 and 20 armies) to place on any vacant board space. If this tile is adjacent to any ally tiles, it will strengthen each tile's defenses +1 (up to a max value of 20). If it is adjacent to any enemy tiles, it will take control over them if its number is higher than the number on the enemy tile. Thoughts on strategy: Here are some initial thoughts; setting the computer AI to Expert will probably teach a lot: minimizing your perimeter seems to be a good strategy, to prevent flips and minimize worst-case damage like in Go, leaving holes inside your formation is lethal, only more so with the hex grid because you can lose armies on up to 6 squares in one move low-numbered tiles are a liability, so place them away from your main territory, near the board edges and scattered. You can also use low-numbered tiles to plug holes in your formation, or make small gains along the perimeter which the opponent will not tend to bother attacking. a triangle formation of three pieces is strong since they mutually reinforce, and also reduce the perimeter Each tile can be flipped at most 6 times, i.e. when its neighbor tiles are occupied. Control of a formation can flow back and forth. Sometimes you lose part of a formation and plug any holes to render that part of the board 'dead' and lock in your territory/ prevent further losses. Low-numbered tiles are obvious-but-low-valued liabilities, but high-numbered tiles can be bigger liabilities if they get flipped (which is harder). One lucky play with a 20-army tile can cause a swing of 200 (from +100 to -100 armies). So tile placement will have both offensive and defensive considerations. Comment 1,2,4 seem to resemble a minimax strategy where we minimize the maximum expected possible loss (modified by some probabilistic consideration of the value ß the opponent can get from 1..20 i.e. a structure which can only be flipped by a ß=20 tile is 'nearly impregnable'.) I'm not clear what the implications of comments 3,5,6 are for optimal strategy. Interested in comments from Go, Chess or Othello players. (The sequel ProximityHD for XBox Live, allows 4-player -cooperative or -competitive local multiplayer increases the branching factor since you now have 5 tiles in your hand at any given time, of which you can only play one. Reinforcement of ally tiles is increased to +2 per ally.)

• AT91SAM7X512's SPI peripheral gets disabled on write to SPI_TDR

  - by Dor

  My AT91SAM7X512's SPI peripheral gets disabled on the X time (X varies) that I write to SPI_TDR. As a result, the processor hangs on the while loop that checks the TDRE flag in SPI_SR. This while loop is located in the function SPI_Write() that belongs to the software package/library provided by ATMEL. The problem occurs arbitrarily - sometimes everything works OK and sometimes it fails on repeated attempts (attemp = downloading the same binary to the MCU and running the program). Configurations are (defined in the order of writing): SPI_MR: MSTR = 1 PS = 0 PCSDEC = 0 PCS = 0111 DLYBCS = 0 SPI_CSR[3]: CPOL = 0 NCPHA = 1 CSAAT = 0 BITS = 0000 SCBR = 20 DLYBS = 0 DLYBCT = 0 SPI_CR: SPIEN = 1 After setting the configurations, the code verifies that the SPI is enabled, by checking the SPIENS flag. I perform a transmission of bytes as follows: const short int dataSize = 5; // Filling array with random data unsigned char data[dataSize] = {0xA5, 0x34, 0x12, 0x00, 0xFF}; short int i = 0; volatile unsigned short dummyRead; SetCS3(); // NPCS3 == PIOA15 while(i-- < dataSize) { mySPI_Write(data[i]); while((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); dummyRead = SPI_Read(); // SPI_Read() from Atmel's library } ClearCS3(); /**********************************/ void mySPI_Write(unsigned char data) { while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); AT91C_BASE_SPI0->SPI_TDR = data; while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TDRE) == 0); // <-- This is where // the processor hangs, because that the SPI peripheral is disabled // (SPIENS equals 0), which makes TDRE equal to 0 forever. } Questions: What's causing the SPI peripheral to become disabled on the write to SPI_TDR? Should I un-comment the line in SPI_Write() that reads the SPI_RDR register? Means, the 4th line in the following code: (The 4th line is originally marked as a comment) void SPI_Write(AT91S_SPI *spi, unsigned int npcs, unsigned short data) { // Discard contents of RDR register //volatile unsigned int discard = spi->SPI_RDR; /* Send data */ while ((spi->SPI_SR & AT91C_SPI_TXEMPTY) == 0); spi->SPI_TDR = data | SPI_PCS(npcs); while ((spi->SPI_SR & AT91C_SPI_TDRE) == 0); } Is there something wrong with the code above that transmits 5 bytes of data? Please note: The NPCS line num. 3 is a GPIO line (means, in PIO mode), and is not controlled by the SPI controller. I'm controlling this line by myself in the code, by de/asserting the ChipSelect#3 (NPCS3) pin when needed. The reason that I'm doing so is because that problems occurred while trying to let the SPI controller to control this pin. I didn't reset the SPI peripheral twice, because that the errata tells to reset it twice only if I perform a reset - which I don't do. Quoting the errata: If a software reset (SWRST in the SPI Control Register) is performed, the SPI may not work properly (the clock is enabled before the chip select.) Problem Fix/Workaround The SPI Control Register field, SWRST (Software Reset) needs to be written twice to be cor- rectly set. I noticed that sometimes, if I put a delay before the write to the SPI_TDR register (in SPI_Write()), then the code works perfectly and the communications succeeds. Useful links: AT91SAM7X Series Preliminary.pdf ATMEL software package/library spi.c from Atmel's library spi.h from Atmel's library An example of initializing the SPI and performing a transfer of 5 bytes is highly appreciated and helpful.

• How to get IMediaControl.Run() to start a file playing with no delay

  - by MusiGenesis

  I am attempting to use DirectShow to play two AVI files consecutively (one after the other) so that there is no interruption in the audio or video when the player transitions from one file to the next. I have two custom controls on my form. Each one is pre-loaded with an AVI file, and before playback begins I set up all the DirectShow interfaces, set the video windows and resize them, call IMediaControl.Run(), then IMediaControl.Pause(), then IMediaSeeking.SetPositions to reset to frame 0, on both controls. On the form, you can see that both files are paused at their initial frames. I then call IMediaControl.Run() on the first control, and wait for it to complete before calling Run() on the second control. Initially, I hooked into the first video's EC_COMPLETE notification message, and used this to start the second. Thinking that this event might be slow to arrive (turns out it is, but for a weird reason), I tried two other approaches: Check the first video's current position inside a timer that goes off every second or so (using IMediaPosition.get_CurrentPosition). When the current position is within a second of the video's stop time (known in advance from IMediaPosition.get_StopTime), I go into a tight while loop and wait for the current position to equal the stop time, and then call Run() on the second video. Same as the first, except I replace the while loop with a call to timeSetEvent from winmm.dll, with a delay set so that it fires right when the first file is supposed to end. I use the callback to Run() the second file. Either of these two methods substantially cuts down the delay between the end of the first file and the beginning of the second, indicating that the EC_COMPLETE message doesn't arrive immediately after the file is complete (I also tried hooking the EC_SEGMENT_COMPLETE message, which is supposed to be used for looping within a file, but apparently nobody supports this - it never occurs on my machine, at least). Doing all of the above has cut the transition delay from as much as a second, down to a barely perceptible glitch; about a third of the time the files transition with no interruption at all, which suggests there's no fundamental reason I can't get this to work all the time. The slight delay is still unacceptable, unfortunately. I assume (and I could easily be wrong) that the remaining delay is due to a slight variable delay between the call to IMediaControl.Run() and when the video actually starts playing. Does anybody know anything I can do to eliminate this little lag? It would also help to be told this is fundamentally impossible for whatever reason, which wouldn't surprise me. I've never encountered a video player in Windows that doesn't have this problem, so it may not be doable. More info: the AVI files I'm playing are completely uncompressed (video and audio are uncompressed), so I don't think the lag is due to DirectShow's having to uncompress the video ahead of play start, although it may still buffer ahead as matter of course (and this may be the source of the problem). I would have though that starting play, pausing and then rewinding to the beginning would fix this. Also, the way I'm handling the transition is to actually have the second control underneath the first; when the first completes playing, I start the second and then call BringToFront on it, creating the appearance of a single video transitioning between the two originals. I don't think the glitch is due to this, because it works perfectly some of the time, and even if this were problematic, it wouldn't explain the matching audio glitch. Even more: I just tried starting the second video 30-50 milliseconds "early" and that seemed to eliminate even more of the gap, so I'm guessing that the lag in Run() is about that long. It appears to be variable, though, so this is still not where I need it to be.

• Silverlight Image Loading Question

  - by Matt

  I'm playing around with Silverlight Images and a listbox. Here's the scenario. Using WCF I grab some images out of my database and, using a custom class, add items to a listbox. It's working great right now. The images load and appear in the listbox, just like I want them to. I want to refine and improve my control just a little more so here's what I've done. <ListBox x:Name="lbMedia" Background="Transparent" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Auto"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <c:WrapPanel></c:WrapPanel> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <im:MediaManagerItem></im:MediaManagerItem> </DataTemplate> </ItemsControl.ItemTemplate> </ListBox> Just a simple listbox. The datatemplate is a custom control and literally it contains a contentpresenter, nothing more. Now the class that I use as the ItemSource has a Source property. Here's what it looks like. private UIElement _LoadingSource; private UIElement _Source; public UIElement Source { get { if( _Source == null ) { LoadMedia(); return new LoadingElement(); } return _Source; } set { if( !( value is Image ) && !( value is MediaElement ) ) throw new Exception( "Media Source must be an Image or MediaElement" ); _Source = value; NotifyPropertyChanged( "Source" ); } } Essentially, on the get I check if the image/video has been loaded from the server. If it hasn't I return a loading control, then I proceed to load my image. Here's the code for my LoadMedia method. private void LoadMedia() { if( _Media != null && _Media.MediaId > 0 ) { //load the media BackgroundWorker mediaLoader = new BackgroundWorker(); mediaLoader.DoWork += mediaLoader_DoWork; mediaLoader.RunWorkerCompleted += mediaLoader_RunWorkerCompleted; mediaLoader.RunWorkerAsync(); } } void mediaLoader_RunWorkerCompleted( object sender, RunWorkerCompletedEventArgs e ) { if(_LoadingSource != null) Source = _LoadingSource; } void mediaLoader_DoWork( object sender, DoWorkEventArgs e ) { string url = App.siteUrl + "download.ashx?MediaId=" + _Media.MediaId; SmartDispatcher.BeginInvoke( () => { Image img = new Image(); img.Source = new BitmapImage( new Uri( url, UriKind.Absolute ) ); _LoadingSource = img; } ); } So as the code goes, I create a new image element, and set the Uri. The images that I'm downloading take about 2-5 seconds to download. Now for the problem / fine tuning. Right now my code will check if the source is null and if it is, return a loading element, and run the background worker to get the image. Once the background worker finishes, set the source to the new downloaded image. I want to be able to set the Source property AFTER the image has fully downloaded. Right now my loading element appears for a brief second, then there's nothing for 2-5 seconds until the image finishes downloading. I want the loading elements to stick around until the image is completely ready but I'm having troubles doing this. I've tried adding a a listener to the ImageOpened event and update the Source property then, but it doesn't work. Thanks in advance.

• How Do I Bind a "selected Item" in a Listbox to a ItemsControl in WPF?

  - by Scott

  LowDown: I am trying to create a Document Viewer in WPF. It will allow the user to preview selected documents and if they want, compare the documents in WPF. So they can view them side by side. The layout is this: Left side is a full list box. On the right side is a Collection or an Items control. Inside the items control will be a collection of the "selected documents" in the list box. So A user can select multiple items in the list box and for each new item they select, they can add the item to the collection on the right. I want the collection to look like a image gallery that shows up in Google/Bing Image searches. Make sense? The problem I am having is I can't get the WPFPreviewer to bind correctly to the selected item in the list box under the itemscontrol. Side Note: The WPFPreviewer is something Micorosft puts out that allows us to preview documents. Other previewers can be built for all types of documents, but im going basic here until I get this working right. I have been successful in binding to the list box WITHOUT the items control here: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid Background="Cyan"> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <l:WPFPreviewHandler Content="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}"/> </Grid> Though, once I add in the ItemsControl, I can't get it to work anymore: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <ItemsControl x:Name="DocumentViewer" ItemsSource="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Background="Cyan"> <l:WPFPreviewHandler Content="{Binding Url}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> Can someone please help me out with trying to bind to the ItemsControl if I select one or even multiple items in the listbox.

• Find optimal strategy and AI for the game 'Proximity'?

• Blend Interaction Behaviour gives "points to immutable instance" error

  - by kennethkryger

  I have a UserControl that is a base class for other user controls, that are shown in "modal view". I want to have all user controls fading in, when shown and fading out when closed. I also want a behavior, so that the user can move the controls around.My contructor looks like this: var tg = new TransformGroup(); tg.Children.Add(new ScaleTransform()); RenderTransform = tg; var behaviors = Interaction.GetBehaviors(this); behaviors.Add(new TranslateZoomRotateBehavior()); Loaded += ModalDialogBase_Loaded; And the ModalDialogBase_Loaded method looks like this: private void ModalDialogBase_Loaded(object sender, RoutedEventArgs e) { var fadeInStoryboard = (Storyboard)TryFindResource("modalDialogFadeIn"); fadeInStoryboard.Begin(this); } When I press a Close-button on the control this method is called: protected virtual void Close() { var fadeOutStoryboard = (Storyboard)TryFindResource("modalDialogFadeOut"); fadeOutStoryboard = fadeOutStoryboard.Clone(); fadeOutStoryboard.Completed += delegate { RaiseEvent(new RoutedEventArgs(ClosedEvent)); }; fadeOutStoryboard.Begin(this); } The storyboard for fading out look like this: <Storyboard x:Key="modalDialogFadeOut"> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)" Storyboard.TargetName="{x:Null}"> <EasingDoubleKeyFrame KeyTime="0" Value="1"> <EasingDoubleKeyFrame.EasingFunction> <BackEase EasingMode="EaseIn" Amplitude="0.3" /> </EasingDoubleKeyFrame.EasingFunction> </EasingDoubleKeyFrame> <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="0"> <EasingDoubleKeyFrame.EasingFunction> <BackEase EasingMode="EaseIn" Amplitude="0.3" /> </EasingDoubleKeyFrame.EasingFunction> </EasingDoubleKeyFrame> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)" Storyboard.TargetName="{x:Null}"> <EasingDoubleKeyFrame KeyTime="0" Value="1"> <EasingDoubleKeyFrame.EasingFunction> <BackEase EasingMode="EaseIn" Amplitude="0.3" /> </EasingDoubleKeyFrame.EasingFunction> </EasingDoubleKeyFrame> <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="0"> <EasingDoubleKeyFrame.EasingFunction> <BackEase EasingMode="EaseIn" Amplitude="0.3" /> </EasingDoubleKeyFrame.EasingFunction> </EasingDoubleKeyFrame> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="{x:Null}"> <EasingDoubleKeyFrame KeyTime="0" Value="1" /> <EasingDoubleKeyFrame KeyTime="0:0:0.3" Value="0" /> <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="0" /> </DoubleAnimationUsingKeyFrames> </Storyboard> If the user control is show, and the user does NOT move it around on the screen, everything works fine. However, if the user DOES move the control around, I get the following error when the modalDialogFadeOut storyboard is started: 'Children' property value in the path '(0).(1)[0].(2)' points to immutable instance of 'System.Windows.Media.TransformCollection'. How can fix this?

I have the following class: public class Day : Control, INotifyPropertyChanged { public static readonly DependencyProperty DateProperty = DependencyProperty.Register("Date", typeof(int), typeof(Day)); public int Date { get { return (int)GetValue(DateProperty); } set { SetValue(DateProperty, value); if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("Date")); } } } public static readonly DependencyProperty DayNameProperty = DependencyProperty.Register("DayName", typeof(String), typeof(Day)); public String DayName { get { return (String)GetValue(DayNameProperty); } set { SetValue(DayNameProperty, value); if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("DayName")); } } } static Day() { DefaultStyleKeyProperty.OverrideMetadata(typeof(Day), new FrameworkPropertyMetadata(typeof(Day))); } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } I've learned that you can't call a constructor that has parameters in XAML so the only way to actually set some data for this class is through the two properties, DayName and Date. I created a ControlTemplate for Day which is as follows: <Style TargetType="{x:Type con:Day}"> <Setter Property="MinHeight" Value="20"/> <Setter Property="MinWidth" Value="80"/> <Setter Property="Height" Value="20"/> <Setter Property="Width" Value="80"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type con:Day}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Rectangle Grid.ColumnSpan="2" x:Name="rectHasEntry" Fill="WhiteSmoke"/> <TextBlock Grid.Column="0" x:Name="textBlockDayName" Text="{TemplateBinding DayName}" FontFamily="Junction" FontSize="11" Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/> <TextBlock Grid.Column="1" x:Name="textBlockDate" Text="{TemplateBinding Date}" FontFamily="Junction" FontSize="11" Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/> <Rectangle Grid.ColumnSpan="2" x:Name="rectMouseOver" Fill="#A2C0DA" Opacity="0" Style="{StaticResource DayRectangleMouseOverStyle}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> I then render it on screen in my MainWindow thusly: <Window x:Class="WPFControlLibrary.TestHarness.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:con="clr-namespace:WPFControlLibrary.Calendar;assembly=WPFControlLibrary" Title="MainWindow" Height="500" Width="525" WindowStartupLocation="CenterScreen"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="80"/> </Grid.ColumnDefinitions> <con:Day Grid.Column="1" Height="20" Width="80" DayName="Mon" Date="1"/> </Grid> And what I actually see is, well, nothing. If I put my cursor on the con:Day line of the XAML it'll highlight the correctly sized rectangle in the window but I don't see "Mon" on the left side of the rectangle and "1" on the right. What am I doing wrong? I suspect it's something simple but I'll be darned if I'm seeing it. My ultimate goal is to group a bunch of the Day controls within a Month control, which is then contained in a Year control as I'm trying to make a long Calendar Bar that lets you navigate through the months and years, while clicking on a Day would display any information saved on that date. But I can't even get the Day part to display independent of anything else so I'm a long way from the rest of the functionality. Any help would be greatly appreciated.

• MSBuild condition across projects

  - by Billy Talented

  I have tried several solutions for this problem. Enough to know I do not know enough about MSBuild to do this elegantly but I feel like there should be a method. I have a set of libraries for working with .net projects. A few of the projects utilize System.Web.Mvc - which recently released Version 2 - and we are looking forward to the upgrade. Currently sites which reference this library reference it directly by the project(csproj) on the developer's computer - not a built version of the library so that changes and source code case easily be viewed when dealing code from this library. This works quite well and would prefer to not have to switch to binary references (but will if this is the only solution). The problem I have is that because of some of the functionality that was added onto the MVC1 based library (view engines, model binders etc) several of the sites reliant on these libraries need to stay on MVC1 until we have full evaluated and tested them on MVC2. I would prefer to not have to fork or have two copies on each dev machine. So what I would like to be able to do is set a property group value in the referencing web application and have this read by the above mentions library with the caviat that when working directly on the library via its containing solution I would like to be able to control this via Configuration Manager by selecting a build type and that property overriding the build behavior of the solution (i.e. 'Debug - MVC1' vs 'Debug -MVC2') - I have this working via: <Choose> <When Condition=" '$(Configuration)|$(Platform)' == 'Release - MVC2|AnyCPU' Or '$(Configuration)|$(Platform)' == 'Debug - MVC2|AnyCPU'"> <ItemGroup> <Reference Include="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> </Reference> <Reference Include="Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\Dependancies\Web\MVC2\Microsoft.Web.Mvc.dll</HintPath> </Reference> </ItemGroup> </When> <Otherwise> <ItemGroup> <Reference Include="System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\Dependancies\Web\MVC\System.Web.Mvc.dll</HintPath> </Reference> </ItemGroup> </Otherwise> The item that I am struggling with is the cross solution issue(solution TheWebsite references this project and needs to control which build property to use) that I have not found a way to work with that I think is a solid solution that enabled the build within visual studio to work as it has to date. Other bits: we are using VS2008, Resharper, TeamCity for CI, SVN for source control.

• Is it possible to embed Cockburn style textual UML Use Case content in the code base to improve code

  - by fooledbyprimes

  experimenting with Cockburn use cases in code I was writing some complicated UI code. I decided to employ Cockburn use cases with fish,kite,and sea levels (discussed by Martin Fowler in his book 'UML Distilled'). I wrapped Cockburn use cases in static C# objects so that I could test logical conditions against static constants which represented steps in a UI workflow. The idea was that you could read the code and know what it was doing because the wrapped objects and their public contants gave you ENGLISH use cases via namespaces. Also, I was going to use reflection to pump out error messages that included the described use cases. The idea is that the stack trace could include some UI use case steps IN ENGLISH.... It turned out to be a fun way to achieve a mini,psuedo light-weight Domain Language but without having to write a DSL compiler. So my question is whether or not this is a good way to do this? Has anyone out there ever done something similar? c# example snippets follow Assume we have some aspx page which has 3 user controls (with lots of clickable stuff). User must click on stuff in one particular user control (possibly making some kind of selection) and then the UI must visually cue the user that the selection was successful. Now, while that item is selected, the user must browse through a gridview to find an item within one of the other user controls and then select something. This sounds like an easy thing to manage but the code can get ugly. In my case, the user controls all sent event messages which were captured by the main page. This way, the page acted like a central processor of UI events and could keep track of what happens when the user is clicking around. So, in the main aspx page, we capture the first user control's event. using MyCompany.MyApp.Web.UseCases; protected void MyFirstUserControl_SomeUIWorkflowRequestCommingIn(object sender, EventArgs e) { // some code here to respond and make "state" changes or whatever // // blah blah blah // finally we have this (how did we know to call fish level method?? because we knew when we wrote the code to send the event in the user control) UpdateUserInterfaceOnFishLevelUseCaseGoalSuccess(FishLevel.SomeNamedUIWorkflow.SelectedItemForPurchase) } protected void UpdateUserInterfaceOnFishLevelGoalSuccess(FishLevel.SomeNamedUIWorkflow goal) { switch (goal) { case FishLevel.SomeNamedUIWorkflow.NewMasterItemSelected: //call some UI related methods here including methods for the other user controls if necessary.... break; case FishLevel.SomeNamedUIWorkFlow.DrillDownOnDetails: //call some UI related methods here including methods for the other user controls if necessary.... break; case FishLevel.SomeNamedUIWorkFlow.CancelMultiSelect: //call some UI related methods here including methods for the other user controls if necessary.... break; // more cases... } } } //also we have protected void UpdateUserInterfaceOnSeaLevelGoalSuccess(SeaLevel.SomeNamedUIWorkflow goal) { switch (goal) { case SeaLevel.CheckOutWorkflow.ChangedCreditCard: // do stuff // more cases... } } } So, in the MyCompany.MyApp.Web.UseCases namespace we might have code like this: class SeaLevel... class FishLevel... class KiteLevel... The workflow use cases embedded in the classes could be inner classes or static methods or enumerations or whatever gives you the cleanest namespace. I can't remember what I did originally but you get the picture.

• Internet Explorer Automation: how to suppress Open/Save dialog?

  - by Vladimir Dyuzhev

  When controlling IE instance via MSHTML, how to suppress Open/Save dialogs for non-HTML content? I need to get data from another system and import it into our one. Due to budget constraints no development (e.g. WS) can be done on the other side for some time, so my only option for now is to do web scrapping. The remote site is ASP.NET-based, so simple HTML requests won't work -- too much JS. I wrote a simple C# application that uses MSHTML and SHDocView to control an IE instance. So far so good: I can perform login, navigate to desired page, populate required fields and do submit. Then I face a couple of problems: First is that report is opening in another window. I suspect I can attach to that window too by enumerating IE windows in the system. Second, more troublesome, is that report itself is CSV file, and triggers Open/Save dialog. I'd like to avoid it and make IE save the file into given location OR I'm fine with programmatically clicking dialog buttons too (how?) I'm actually totally non-Windows guy (unix/J2EE), and hope someone with better knowledge would give me a hint how to do those tasks. Thanks! UPDATE I've found a promising document on MSDN: http://msdn.microsoft.com/en-ca/library/aa770041.aspx Control the kinds of content that are downloaded and what the WebBrowser Control does with them once they are downloaded. For example, you can prevent videos from playing, script from running, or new windows from opening when users click on links, or prevent Microsoft ActiveX controls from downloading or executing. Slowly reading through... UPDATE 2: MADE IT WORK, SORT OF... Finally I made it work, but in an ugly way. Essentially, I register a handler "before navigate", then, in the handler, if the URL is matching my target file, I cancel the navigation, but remember the URL, and use WebClient class to access and download that temporal URL directly. I cannot copy the whole code here, it contains a lot of garbage, but here are the essential parts: Installing handler: _IE2.FileDownload += new DWebBrowserEvents2_FileDownloadEventHandler(IE2_FileDownload); _IE.BeforeNavigate2 += new DWebBrowserEvents2_BeforeNavigate2EventHandler(IE_OnBeforeNavigate2); Recording URL and then cancelling download (thus preventing Save dialog to appear): public string downloadUrl; void IE_OnBeforeNavigate2(Object ob1, ref Object URL, ref Object Flags, ref Object Name, ref Object da, ref Object Head, ref bool Cancel) { Console.WriteLine("Before Navigate2 "+URL); if (URL.ToString().EndsWith(".csv")) { Console.WriteLine("CSV file"); downloadUrl = URL.ToString(); } Cancel = false; } void IE2_FileDownload(bool activeDocument, ref bool cancel) { Console.WriteLine("FileDownload, downloading "+downloadUrl+" instead"); cancel = true; } void IE_OnNewWindow2(ref Object o, ref bool cancel) { Console.WriteLine("OnNewWindow2"); _IE2 = new SHDocVw.InternetExplorer(); _IE2.BeforeNavigate2 += new DWebBrowserEvents2_BeforeNavigate2EventHandler(IE_OnBeforeNavigate2); _IE2.Visible = true; o = _IE2; _IE2.FileDownload += new DWebBrowserEvents2_FileDownloadEventHandler(IE2_FileDownload); _IE2.Silent = true; cancel = false; return; } And in the calling code using the found URL for direct download: ... driver.ClickButton(".*_btnRunReport"); driver.WaitForComplete(); Thread.Sleep(10000); WebClient Client = new WebClient(); Client.DownloadFile(driver.downloadUrl, "C:\\affinity.dump"); (driver is a simple wrapper over IE instance = _IE) Hope that helps someone.

• Winforms controls and "generic" events handlers. How can I do this?

  - by Yanko Hernández Alvarez

  In the demo of the ObjectListView control there is this code (in the "Complex Example" tab page) to allow for a custom editor (a ComboBox) (Adapted to my case and edited for clarity): EventHandler CurrentEH; private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) { ISomeInterface M = (e.RowObject as ObjectListView1Row).SomeObject; //(1) ComboBox cb = new ComboBox(); cb.Bounds = e.CellBounds; cb.DropDownStyle = ComboBoxStyle.DropDownList; cb.DataSource = ISomeOtherObjectCollection; cb.DisplayMember = "propertyName"; cb.DataBindings.Add("SelectedItem", M, "ISomeOtherObject", false, DataSourceUpdateMode.Never); e.Control = cb; cb.SelectedIndexChanged += CurrentEH = (object sender2, EventArgs e2) => M.ISomeOtherObject = (ISomeOtherObject)((ComboBox)sender2).SelectedValue; //(2) } } private void ObjectListView_CellEditFinishing(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) { // Stop listening for change events ((ComboBox)e.Control).SelectedIndexChanged -= CurrentEH; // Any updating will have been down in the SelectedIndexChanged // event handler. // Here we simply make the list redraw the involved ListViewItem ((ObjectListView)sender).RefreshItem(e.ListViewItem); // We have updated the model object, so we cancel the auto update e.Cancel = true; } } I have too many other columns with combo editors inside objectlistviews to use a copy& paste strategy (besides, copy&paste is a serious source of bugs), so I tried to parameterize the code to keep the code duplication to a minimum. ObjectListView_CellEditFinishing is a piece of cake: HashSet<OLVColumn> cbColumns = new HashSet<OLVColumn> (new OLVColumn[] { SomeCol, SomeCol2, ...}; private void ObjectListView_CellEditFinishing(object sender, CellEditEventArgs e) { if (cbColumns.Contains(e.Column)) ... but ObjectListView_CellEditStarting is the problematic. I guess in CellEditStarting I will have to discriminate each case separately: private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) // code to create the combo, put the correct list as the datasource, etc. else if (e.Column == SomeOtherCol) // code to create the combo, put the correct list as the datasource, etc. And so on. But how can I parameterize the "code to create the combo, put the correct list as the datasource, etc."? Problem lines are (1) Get SomeObject. the property NAME varies. (2) Set ISomeOtherObject, the property name varies too. The types vary too, but I can cover those cases with a generic method combined with a not so "typesafe" API (for instance, the cb.DataBindings.Add and cb.DataSource both use an object) Reflection? more lambdas? Any ideas? Any other way to do the same? PS: I want to be able to do something like this: private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) SetUpCombo<ISomeInterface>(ISomeOtherObjectCollection, "propertyName", SomeObject, ISomeOtherObject); else if (e.Column == SomeOtherCol) SetUpCombo<ISomeInterface2>(ISomeOtherObject2Collection, "propertyName2", SomeObject2 ISomeOtherObject2); and so on. Or something like that. I know, parameters SomeObject and ISomeOtherObject are not real parameters per see, but you get the idea of what I want. I want not to repeat the same code skeleton again and again and again. One solution would be "preprocessor generics" like C's DEFINE, but I don't thing c# has something like that. So, does anyone have some alternate ideas to solve this?

• How to get XML into a Dictionary with an Expression?

"" : (string)fund.Attribute("append") }).ToList() }).ToDictionary(xx => xx.Heading, xx => xx.Funds)}; I'm trying to change my code such that I can assign the dictionary directly to a property of the class I'm working in, as described in this question. I'd like to have a Dictionary() where each header text is the key to the list of funds under it. I'm having difficulty applying the example in the linked question because that only returns a string, and this needs to return the dictionary. This is the point that I got to before it occurred to me that I'm lost!!!: this.PerformancePanels = doc.Elements("PerformancePanel").Select(e => { var control = (PerformancePanel)LoadControl(this.OfflineFactsheetPath + (string)e.Attribute("page")); control.PerformanceFunds = e.Elements("FundGroup").Select(f => { List<Fund> funds = (from fund in e.Elements("fund") select new Fund { FundId = (int)fund.Attribute("id"), CountryId = (string)fund.Attribute("countryid"), FundIndex = (fund.Attribute("index") == null) ? null : new Index { Id = (int)fund.Attribute("index") }, FundNameAppend = (fund.Attribute("append") == null) ? "" : (string)fund.Attribute("append") }).ToList(); string heading = (e.Attribute("heading") == null) ? "" : (string)e.Attribute("heading"); }).ToDictionary(xx => heading, xx => Funds); return control; }).ToList(); Could someone point me in the right direction please? I'm not even sure if 'Expression' is the right terminology. Could someone fill me in on that too? Thanks.

• Log4j: Events appear in the wrong logfile

  - by Markus

  Hi there! To be able to log and trace some events I've added a LoggingHandler class to my java project. Inside this class I'm using two different log4j logger instances - one for logging an event and one for tracing an event into different files. The initialization block of the class looks like this: public void initialize() { System.out.print("starting logging server ..."); // create logger instances logLogger = Logger.getLogger("log"); traceLogger = Logger.getLogger("trace"); // create pattern layout String conversionPattern = "%c{2} %d{ABSOLUTE} %r %p %m%n"; try { patternLayout = new PatternLayout(); patternLayout.setConversionPattern(conversionPattern); } catch (Exception e) { System.out.println("error: could not create logger layout pattern"); System.out.println(e); System.exit(1); } // add pattern to file appender try { logFileAppender = new FileAppender(patternLayout, logFilename, false); traceFileAppender = new FileAppender(patternLayout, traceFilename, false); } catch (IOException e) { System.out.println("error: could not add logger layout pattern to corresponding appender"); System.out.println(e); System.exit(1); } // add appenders to loggers logLogger.addAppender(logFileAppender); traceLogger.addAppender(traceFileAppender); // set logger level logLogger.setLevel(Level.INFO); traceLogger.setLevel(Level.INFO); // start logging server loggingServer = new LoggingServer(logLogger, traceLogger, serverPort, this); loggingServer.start(); System.out.println(" done"); } To make sure that only only thread is using the functionality of a logger instance at the same time each logging / tracing method calls the logging method .info() inside a synchronized-block. One example looks like this: public void logMessage(String message) { synchronized (logLogger) { if (logLogger.isInfoEnabled() && logFileAppender != null) { logLogger.info(instanceName + ": " + message); } } } If I look at the log files, I see that sometimes a event appears in the wrong file. One example: trace 10:41:30,773 11080 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1267093 to vehicle 1055293 (slaveControl 1) trace 10:41:30,784 11091 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1156513 to vehicle 1105792 (slaveControl 1) trace 10:41:30,796 11103 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1104306 to vehicle 1055293 (slaveControl 1) trace 10:41:30,808 11115 INFO masterControl(192.168.2.21): vehicle 1327879 was pushed to slave control 1 10:41:30,808 11115 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1101572 to vehicle 106741 (slaveControl 1) trace 10:41:30,820 11127 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1055293 to vehicle 1104306 (slaveControl 1) I think that the problem occures everytime two event happen at the same time (here: 10:41:30,808). Does anybody has an idea how to solve my problem? I already tried to add a sleep() after the method call, but that doesn't helped ... BR, Markus Edit: logtrace 11:16:07,75511:16:07,755 1129711297 INFOINFO masterControl(192.168.2.21): string broadcast message was pushed from 1291400 to vehicle 1138272 (slaveControl 1)masterControl(192.168.2.21): vehicle 1333770 was added to slave control 1 or log 11:16:08,562 12104 INFO 11:16:08,562 masterControl(192.168.2.21): string broadcast message was pushed from 117772 to vehicle 1217744 (slaveControl 1) 12104 INFO masterControl(192.168.2.21): vehicle 1169775 was pushed to slave control 1 Edit 2: It seems like the problem only occurs if logging methods are called from inside a RMI thread (my client / server exchange information using RMI connections). ... Edit 3: I solved the problem by myself: It seems like log4j is NOT completely thread-save. After synchronizing all log / trace methods using a separate object everything is working fine. Maybe the lib is writing the messages to a thread-unsafe buffer before writing them to file?
