• Android RelativeLayout fill_parent unexpected behavior in a ListView with varying row heights

  - by Jameel Al-Aziz

  I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution. To start, here is my row item layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:padding="10dip" android:layout_height="fill_parent" android:maxHeight="64dip" android:minHeight="?android:attr/listPreferredItemHeight"> <ImageView android:id="@+id/infoimage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:clickable="true" android:src="@drawable/info_icon_big" android:layout_alignParentRight="true" android:layout_centerVertical="true"/> <View android:id="@+id/divider" android:background="@drawable/divider_vertical_dark" android:layout_marginLeft="11dip" android:layout_toLeftOf="@+id/infoimage" android:layout_width="1px" android:layout_height="fill_parent" android:layout_marginTop="5dip" android:layout_marginBottom="5dip" android:layout_marginRight="4dip"/> <TextView android:id="@+id/TextView01" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_toRightOf="@+id/ImageView01" android:layout_toLeftOf="@+id/divider" android:gravity="left|center_vertical" android:layout_marginLeft="4dip" android:layout_marginRight="4dip"/> <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:background="@drawable/bborder" android:layout_centerVertical="true"/> </RelativeLayout> The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height. Here is a portion of the getView() method: public View getView(int position, View view, ViewGroup parent) { if (view == null) { view = inflater.inflate(R.layout.tag_list_item, parent, false); } The rest of the method simply sets the appropriate text and images for the row. Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context); Am I missing something essential? Or does fill_parent just not work with dynamic heights?

• procdump on w3wp.exe: Only part of a ReadProcessMemory or WriteProcessMemory request was completed

  - by JakeS

  I'm having a problem with an IIS application that occasionally spikes up in CPU usage, and am trying to use procdump to get a memory dump for examination. I'm running "procdump.exe -64 -mA 9999" where 9999 is the pid of the process. But every time I do it, I get an error: Only part of a ReadProcessMemory or WriteProcessMemory request was completed. Doing this also recycles the apppool, relieving the CPU spike, so I can't keep trying until I get it right. Does anyone know what is going wrong? EDIT WITH MORE INFO: So far I've failed to generate a debug dump no matter what tool I try. All of them seem to generate the same sort of error. This is 2008 R2 Datacenter running IIS7 with a 64-bit asp.net web site. My best guess is that something is getting blocked, causing some requests to remain open in IIS and gradually using up resources. If I monitor the worker process using the IIS Manager and view all requests, throughout the day I'll start to see some requests that "stick" and run forever. Some of these are for static files. Some are for aspx pages. I cannot see any "common" reason for them. Every once in a while the app pool starts taking up 100% CPU and the only remedy is to kill it.

• C# TextBox Autocomplete (Winforms) key events and customization?

  - by m0s

  Hi, I was wondering if it is possible to catch key events for auto-complete list. For example instead of Enter key press for auto-complete use lets say Tab key. Also is it possible to change the colors and add background image for the auto-complete pop-up list? Currently I have my own implementation which is a separate window(form) with a list-box, which works OK, but Id really like to use .net's auto-complete if it can do what I need. Thanks for attention.

• Silverlight animation not smooth

  - by Andrej

  Hi, When trying to animate objects time/frame based in Silverlight (in contrast to using something like DoubleAnimation or Storyboard, which is not suitable e.g. for fast paced games), for example moving a spaceship in a particular direction every frame, the movement is jumpy and not really smooth. The screen even seems to tear. There seems to be no difference between CompositionTarget and DistpatcherTimer. I use the following approach (in pseudocode): Register Handler to Tick-Event of a DispatcherTimer In each Tick: Compute the elapsed time from the last frame in milliseconds Object.X += movementSpeed * ellapsedMilliseconds This should result in a smooth movement, right? But it doesn't. Here is an example (Controls: WASD and Mouse): Silverlight Game. Although the effect I described is not too prevalent in this sample, I can assure you that even moving a single rectangle over a canvas produces a jumpy animation. Does someone have an idea how to minimize this. Are there other approaches to to frame based animation exept using Storyboards/DoubleAnimations which could solve this? Edit: Here a quick and dirty approach, animating a rectangle with minimum code (Controls: A and D) Animation Sample Xaml: <Grid x:Name="LayoutRoot" Background="Black"> <Canvas Width="1000" Height="400" Background="Blue"> <Rectangle x:Name="rect" Width="48" Height="48" Fill="White" Canvas.Top="200" Canvas.Left="0"/> </Canvas> </Grid> C#: private bool isLeft = false; private bool isRight = false; private DispatcherTimer timer = new DispatcherTimer(); private double lastUpdate; public Page() { InitializeComponent(); timer.Interval = TimeSpan.FromMilliseconds(1); timer.Tick += OnTick; lastUpdate = Environment.TickCount; timer.Start(); } private void OnTick(object sender, EventArgs e) { double diff = Environment.TickCount - lastUpdate; double x = Canvas.GetLeft(rect); if (isRight) x += 1 * diff; else if (isLeft) x -= 1 * diff; Canvas.SetLeft(rect, x); lastUpdate = Environment.TickCount; } private void UserControl_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.D) isRight = true; if (e.Key == Key.A) isLeft = true; } private void UserControl_KeyUp(object sender, KeyEventArgs e) { if (e.Key == Key.D) isRight = false; if (e.Key == Key.A) isLeft = false; } Thanks!

• Binding WPF DataGrid to DataTable using TemplateColumns

  - by Chris J

  I have tried everything and got nowhere so I'm hoping someone can give me the aha moment. I simply cannot get the binding to pull the data in the datagrid successfully. I have a DataTable that contains multiple columns with of MyDataType} public class MyData { string nameData {get;set;} boolean showData {get;set;} } MyDataType has 2 properties (A string, a boolean) I have created a test DataTable DataTable GetDummyData() { DataTable dt = new DataTable("Foo"); dt.Columns.Add(new DataColumn("AnotherColumn", typeof(MyData))); dt.Rows.Add(new MyData("Row1C1", true)); dt.Rows.Add(new MyData("Row2C1", false)); dt.AcceptChanges(); return dt; } I have a WPF DataGrid which I want to show my DataTable. But all I want to do is to change how each cell is rendered to show [TextBlock][Button] per cell with values bound to the MyData object and this is where I'm having a tonne of trouble. My XAML looks like this <Window.Resources><ResourceDictionary><DataTemplate x:Key="MyDataTemplate" DataType="MyData"> <StackPanel Orientation="Horizontal" > <Button Background="Green" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5,0,0,0" Content="{Binding Path=nameData}"></Button> <TextBlock Background="Green" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Text="{Binding Path=nameData}"></TextBlock> </StackPanel> </DataTemplate></ResourceDictionary></Window.Resources> <Grid> <dg:DataGrid Grid.Row="1" AutoGenerateColumns="True" x:Name="dataGrid1" SelectionMode="Single" CanUserAddRows="False" CanUserSortColumns="true" CanUserDeleteRows="False" AlternatingRowBackground="AliceBlue" AutoGeneratingColumn="dataGrid1_AutoGeneratingColumn" ItemsSource="{Binding}" /> now all I do once loaded is to attempt to bind the DataTable to the WPF DataGrid dt = GetDummyData(); dataGrid1.ItemsSource = dt.DefaultView; The TextBlock and Button show up, but they don't bind, which leaves them blank. Could anyone let me know if they have any idea how to fix this. This should be simple, thats what Microsoft leads us to believe. I have set the Column.CellTemplate during the AutoGenerating event and still get no binding. Please help!!!

• Silverlight and Unexpected Font Sizes

  - by Eric J.

  Someone please teach me to fish here... I'm just learning Silverlight and have ran into a few situations where the font size actually used is drastically different than I would expect. There's probably something conceptual that I'm missing. Case A In one instance, I have defined a user control that presents a Label to show text. If one clicks on the label, the label (that is in a stack panel, in the user control) is replaced with a TextBox. When used at the top of a page (as in the example below with lblName) the label text is very small (around 8 points). When clicked on, the text box that replaces the label uses the specified fonts size. That same user control, used in different parts of the app, uses the same font for Label and TextBox. <Grid x:Name="LayoutRoot" Background="White"> <Grid.RowDefinitions> <RowDefinition Height="33" /> <RowDefinition Height="267*" /> </Grid.RowDefinitions> <StackPanel Height="Auto" HorizontalAlignment="Left" Name="stackPanel" VerticalAlignment="Top" Width="Auto" Grid.Row="1" /> <my:EditLabel Height="33" HorizontalAlignment="Left" x:Name="lblName" VerticalAlignment="Top" Width="Auto" FlexText="{Binding Name, Mode=TwoWay}" FontSize="20" MinHeight="24" /> </Grid> Case B I'm using the LiquidMenu.Menu control to pop up a menu when a button is pressed. The font looks huge compared to the rest of my page (maybe 36 points?). I tried forcing it to a very small by explicitly setting it to 8pt, but that had no effect. <Grid x:Name="LayoutRoot" Background="{x:Null}"> <StackPanel x:Name="labelStackPanel" Orientation="Horizontal"> <TextBlock Height="24" HorizontalAlignment="Left" Name="labelText" VerticalAlignment="Top" Width="200" Text="(Value Goes Here)" /> </StackPanel> <liquidMenu:Menu x:Name="popupMenu" Canvas.Left="40" Canvas.Top="40" ItemSelected="MenuList_ItemSelected" Visibility="Collapsed" Height="Auto" FontSize="8"> <liquidMenu:MenuItem ID="delete" Icon="Images/Delete10.png" Text="Delete" Shortcut="Del" /> <liquidMenu:MenuItem ID="exclusive" Icon="" Text="Exclusive" Shortcut="Ctrl+E" /> <liquidMenu:MenuItem ID="properties" Icon="" Text="Properties" Shortcut="Ctrl+P" /> </liquidMenu:Menu> </Grid> Answers to these specific issues are great, a new way to think about this type of issue so that I understand how to control font size is better.

• How to use Android GradientDrawable

  - by Janusz

  I try to use the GradientDrawable to set a gradient to some backgrounds and buttons. Sadly the documentation is not very detailed. What are the main attributes to configure the gradient? I understand start and endcolor but some of the other attributes could need some explanation. At the moment I used images as the background for the buttons but a drawable defined in XML would be much nicer. I try to get a look like this (It is a very light gradient):

• Ipsec reload fails to load ipsec.conf Strongswan 5.0

  - by Quentin Swain

  I am having trouble configuring a connection to an Android device using a fedora 17 linux machine and strongSwanv5.0.1dr2. I have made some progress but when I try adding the configuration to support xauth authentication I receive an error when I try to reload the configuration file. I get a similar error for the value ikev1 for the keyexchange setting , and whenever i try to set a value for rightauth. Has anyone else had this problem The man page for ipsec.conf and the documentation on the strongswan wiki both indicated that these settings and values should be fine in 5.0.x.x. I could try setting authby but that is deprecated according to the documentation i read and the xauthpsk value isn't working. Any help is much appreciated thanks. can not load config '/etc/ipsec.conf': /etc/ipsec.conf:25: syntax error, unexpected STRING [leftauth] # /etc/ipsec.conf - Openswan IPsec configuration file # # Manual: ipsec.conf.5 # # Please place your own config files in /etc/ipsec.d/ ending in .conf version 2.0 # conforms to second version of ipsec.conf specification # basic configuration config setup # For Red Hat Enterprise Linux and Fedora, leave protostack=netkey protostack=netkey # Enable this if you see "failed to find any available worker" # nhelpers=0 plutodebug=all conn %default ikelifetime=240m #keylifetime=20m keyingtries=3 ikev2=no conn android left=10.1.12.212 right=10.1.12.140 leftxauthserver=yes leftauth=psk rightauth=xauth keyexchange=ikev1 type=tunnel pfs=no rekey=no auto=start ike=aes256-md5;modp1024 phase2=esp ikev2=no #You may put your configuration (.conf) file in the "/etc/ipsec.d/" #include /etc/ipsec.d/*.conf

• Issues with ProxyPass and ProxyPassReverse when proxying to localhost and a different TCP port

  - by mbrownnyc

  I am attempting to use ProxyPass and ProxyPassReverse to proxy requests through Apache to another server instance that is bound to the localhost on a different TCP port that the Vhost exists (VHost is bound to :80, when the target is bound to :5000). However, I am repeatedly receiving HTTP 503 when accessing the Location. According to the ProxyPass documentation... <VirtualHost *:80> ServerName apacheserver.domain.local DocumentRoot /var/www/redmine/public ErrorLog logs/redmine_error <Directory /var/www/redmine/public> Allow from all Options -MultiViews Order allow,deny AllowOverride all </Directory> </VirtualHost> PassengerTempDir /tmp/passenger <Location /rhodecode> ProxyPass http://127.0.0.1:5000/rhodecode ProxyPassReverse http://127.0.0.1:5000/rhodecode SetEnvIf X-Url-Scheme https HTTPS=1 </Location> I have tested binding the alternate server to the interface IP address, and the same issue occurs. The server servicing request is an instance of python paste:httpserver, and it has been configured to use the /rhodecode suffix (as I saw this to be mentioned in other posts about ProxyPass). The documentation from the project itself, Rhodecode, reports to use the above. The issue is persistent if I target another server that is serving on a different port. Does ProxyPass allow proxying to a different TCP port? [update] I won't delete this, in case someone comes across the same issue. I had set an ErrorLog, and in that ErrorLog the following error was reported: [Wed Nov 09 11:36:35 2011] [error] (13)Permission denied: proxy: HTTP: attempt to connect to 127.0.0.1:5000 (192.168.100.100) failed [Wed Nov 09 11:36:35 2011] [error] ap_proxy_connect_backend disabling worker for (192.168.100.100) After some more research, I attempted to set SELinux to permissive (echo 0 >/selinux/enforce), and try again. It turns out the SELinux boolean httpd_can_network_connect must be set to 1. For persistence on reboot: setsebool -P httpd_can_network_connect=1

• WPF XAML: how to get StackPanel's children to fill maximum space downward?

  - by Edward Tanguay

  I simply want flowing text on the left, and a help box on the right. The help box should extend all the way to the bottom. If you take out the outer StackPanel below it works great. But for reasons of layout (I'm inserting UserControls dynamically) I need to have the wrapping StackPanel. How do I get the GroupBox to extend down to the bottom of the StackPanel, as you can see I've tried: VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Height="Auto" XAML: <Window x:Class="TestDynamic033.Test3" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test3" Height="300" Width="600"> <StackPanel VerticalAlignment="Stretch" Height="Auto"> <DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" Margin="10"> <GroupBox DockPanel.Dock="Right" Header="Help" Width="100" Background="Beige" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Height="Auto"> <TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" /> </GroupBox> <StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch"> <TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/> </StackPanel> </DockPanel> </StackPanel> </Window> Answer: Thanks Mark, using DockPanel instead of StackPanel cleared it up. In general, I find myself using DockPanel more and more now for WPF layouting, here's the fixed XAML: <Window x:Class="TestDynamic033.Test3" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test3" Height="300" Width="600" MinWidth="500" MinHeight="200"> <DockPanel VerticalAlignment="Stretch" Height="Auto"> <DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" MinWidth="400" Margin="10"> <GroupBox DockPanel.Dock="Right" Header="Help" Width="100" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Height="Auto"> <Border CornerRadius="3" Background="Beige"> <TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" Padding="5"/> </Border> </GroupBox> <StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch"> <TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/> </StackPanel> </DockPanel> </DockPanel> </Window>

• jQuery doesn't work in IE8?

  - by Wade D Ouellet

  Hi, I am working on a site here: mfm.treethink.net All the jquery works fine in Firefox, Chrome and Safari but on IE8 it gives me errors and the banner at the top doesn't work (which uses the crossSlide jQuery plugin) and as well the image rollovers don't work with the colour change. IE8 is telling me that the errors are on lines 53, 134 and 149 in the source, all of those lines are where the jquery function is declared. $(document).ready(function(){ I am running jquery 1.4. Oddly enough, the other piece of jQuery I have on that page works, the artist browse/select menu on the right. But the banner and image rollovers don't. Here are all the scripts I'm running: 1: the banner - doesn't work in IE8 <script type="text/javascript"> $(function() { $('#banner').crossSlide({ sleep: 5, fade: 1 }, [ <?php $pages = get_posts('numberposts=2000&post_type=artist&post_status=publish'); $i = 1; foreach( $pages as $page ) { $content = $page->post_title; if( empty($content) ) continue; $content = apply_filters('the_content', $content); ?> { src: '/wp-content/uploads/<?php echo $page->post_name ?>.jpg' }, <?php $i++; } ?> ]); }); </script> 2 - image rollovers - doesn't work in IE8 <script type="text/javascript"> $(function(){ $("ul#artists li").hover(function() { /* On hover */ var thumbOver = $(this).find("img").attr("src"); /* Find image source */ /* Swap background */ $(this).find("a.thumb").css({'background' : 'url(' + thumbOver + ') center bottom no-repeat'}); $(this).find("span").stop().fadeTo('fast', 0 , function() { $(this).hide() }); } , function() { $(this).find("span").stop().fadeTo('fast', 1).show(); }); }); </script> 3 - the artist select - works in IE 8 <script> $("#browse-select").change(function() { window.location.href = $(this).val(); }); </script> These scripts were done by referencing previously made scripts, like I said I'm still new to jQuery. The second works in IE8 and the first one is the one that doesn't. I noticed the third one, the only one working, is written differently than the first two non-working ones without a function declaration at the top. Could this have anything to do with it? Any help figuring out this problem would be so appreciated. Thanks a lot, Wade

• Rx Reactive extensions: Unit testing with FromAsyncPattern

  - by Andrew Anderson

  The Reactive Extensions have a sexy little hook to simplify calling async methods: var func = Observable.FromAsyncPattern<InType, OutType>( myWcfService.BeginDoStuff, myWcfService.EndDoStuff); func(inData).ObserveOnDispatcher().Subscribe(x => Foo(x)); I am using this in an WPF project, and it works great at runtime. Unfortunately, when trying to unit test methods that use this technique I am experiencing random failures. ~3 out of every five executions of a test that contain this code fails. Here is a sample test (implemented using a Rhino/unity auto-mocking container): [TestMethod()] public void SomeTest() { // arrange var container = GetAutoMockingContainer(); container.Resolve<IMyWcfServiceClient>() .Expect(x => x.BeginDoStuff(null, null, null)) .IgnoreArguments() .Do( new Func<Specification, AsyncCallback, object, IAsyncResult>((inData, asyncCallback, state) => { return new CompletedAsyncResult(asyncCallback, state); })); container.Resolve<IRepositoryServiceClient>() .Expect(x => x.EndRetrieveAttributeDefinitionsForSorting(null)) .IgnoreArguments() .Do( new Func<IAsyncResult, OutData>((ar) => { return someMockData; })); // act var target = CreateTestSubject(container); target.DoMethodThatInvokesService(); // Run the dispatcher for everything over background priority Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new Action(() => { })); // assert Assert.IsTrue(my operation ran as expected); } The problem that I see is that the code that I specified to run when the async action completed (in this case, Foo(x)), is never called. I can verify this by setting breakpoints in Foo and observing that they are never reached. Further, I can force a long delay after calling DoMethodThatInvokesService (which kicks off the async call), and the code is still never run. I do know that the lines of code invoking the Rx framework were called. Other things I've tried: I have attempted to modify the second last line according to the suggestions here: Reactive Extensions Rx - unit testing something with ObserveOnDispatcher No love. I have added .Take(1) to the Rx code as follows: func(inData).ObserveOnDispatcher().Take(1).Subscribe(x = Foo(x)); This improved my failure rate to something like 1 in 5, but they still occurred. I have rewritten the Rx code to use the plain jane Async pattern. This works, however my developer ego really would love to use Rx instead of boring old begin/end. In the end I do have a work around in hand (i.e. don't use Rx), however I feel that it is not ideal. If anyone has ran into this problem in the past and found a solution, I'd dearly love to hear it.

• Unable to install PHP-FPM on Apache (Failed to connect to FastCGI server)

  - by Nyxynyx

  I have been having problem installing php-fpm for use with apache2-mpm-worker. This is the guide that I am following. According to the guide's Step 5, Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -host 127.0.0.1:9000 -pass-header Authorization However I cannot find php5-fcgi at /usr/lib, but only /usr/bin/php5-cgi and /usr/bin/php-cgi, which I am not sure if they are the same. So I changed the lines in Step 5 to: Alias /php5-fcgi /usr/bin/php5-fcgi FastCgiExternalServer /usr/bin/php5-fcgi -host 127.0.0.1:9000 -pass-header On restarting Apache, it's logs gave the errors: [notice] caught SIGTERM, shutting down [alert] (4)Interrupted system call: FastCGI: read() from pipe failed (0) [alert] (4)Interrupted system call: FastCGI: the PM is shutting down, Apache seems to have disappeared - bye [notice] Apache/2.2.22 (Ubuntu) mod_fastcgi/mod_fastcgi-SNAP-0910052141 configured -- resuming normal operations [notice] FastCGI: process manager initialized (pid 16348) And on loading the index page [error] [client 10.0.2.2] (111)Connection refused: FastCGI: failed to connect to server "/usr/bin/php5-cgi": connect() failed [error] [client 10.0.2.2] FastCGI: incomplete headers (0 bytes) received from server "/usr/bin/php5-cgi" [error] [client 10.0.2.2] File does not exist: /var/www/mydomain/public/favicon.ico Question: Any idea why php5-fcgi is missing, and how should this problem be fixed?

• What is Jquery's alternative to Mootools MochaUI?

  - by chris

  MochaUI is very intuitive and the modal iframes almost perfectly replicate Windows. Unfortunately, I have scripts written in Jquery that I use, and I hear there are conflicts when putting both Mootools and Jquery on one html file (is this true?). How can I get the MochaUI features in Jquery? At the very least, is there a similar modal dialog system? I've seen JqueryUI Dialog but it makes the background go dark and nonfunctional, which is not what I am looking for.

• How to find virtualization performance bottlenecks?

  - by Martin

  We have recently started moving our C++ build server(s) from real machines into VMs. (MS Hyper-V) We have some performance issues that I've currently no idea how to address. We have: Test-Box - this is a piece of desktop workstation hardware my co-worker used to set up the VM before we moved it to the actual server hardware Srv-Box - this is the server hardware Test-Box-Real - This is Windows running directly on the Test-Box HW Test-Box-VM - This is Windows in a Hyper-V VM on the Test-Box HW Srv-Box-Real- This is Server2008R2 running on the Srv-Box HW. Srv-Box-VM- This is Windows running in a Hyper-V VM on the Srv-Box HW, i.e. on Srv-Box-Real. Now, the problem is that we compared Build times between Test-Box-Real and Test-Box-VM and they were basically equal (within about 2%). Then we moved the VM to the Srv-Box machine and what we saw there is that we have a significant performance degradation between Srv-Box-Real and Srv-Box-VM, that is, where we saw no differences on the Test HW we now do see major differences in performance on the actual Server HW. (Builds about ~~ 50% slower inside the VM.) I should add that both the Test-Box and the Srv-Box are only running this one single VM and doing nothing else. I should also note that the "Real" OS is Win2008R2(64bit) and the VM hosted OS is Wind2003R2(32bit). Hardware specs: Srv-Box: Intel XEON E5640 @ 2.67Ghz (This means 8 cores with hyperthreading on the Real system and "only" 4 cores on the VM, since Hyper-V doesn't allow for hyperthreading, but number of cores doesn't seem to explain the problem here.) 16GB RAM (we have 4GB assigned to the VM) Virtual DELL RAID 1 (2x 450GB HUS156045VLS600 Hitachi 15k SAS drives) Test-Box: Intel XEON E31245 @ 3.3GHz 16GB RAM WD VelociRaptor 600GB 10k RPM SATA Note again that I'm only concerned with the differences between Srv-Box-Real and Srv-Box-VM (high) vs. the differences seen btw. Test-Box-Real and Test-Box-VM (low). Why would one machine have parity when comparing VM vs Real performance and the other (server grade HW no less) would have a large disparity? (Both being XEON CPUs ...)

• WPF Memory Leak

  - by Oskar Kjellin

  I have an WPF form that I myself did not create, so I am not very good at WPF. It is leaking badly though, up to 400 MB and closing the form does not help. The problem lies in my application loading all the pictures at once. I would like to only load the ones visible at the moment. It is about 300 pictures and they are a bit large so my WPF-form suffers from loading them all. I have a DataTemplate with my own type that has a property Thumbnail. The code in the template is like this: <Image Source="{Binding Path=Thumbnail}" Stretch="Fill"/> And then I have a grid with a control that has the above template as source. The code for this control is the below. Please provide me with hints on how to optimize the code and perhaps get the only ones that are visible and only have that many controls loaded at the same time? <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Controls:ElementFlow"> <Grid Background="{TemplateBinding Background}"> <Canvas x:Name="PART_HiddenPanel" IsItemsHost="True" Visibility="Hidden" /> <Viewport3D x:Name="PART_Viewport"> <!-- Camera --> <Viewport3D.Camera> <PerspectiveCamera FieldOfView="60" Position="0,1,4" LookDirection="0,-1,-4" UpDirection="0,1,0" /> </Viewport3D.Camera> <ContainerUIElement3D x:Name="PART_ModelContainer" /> <ModelVisual3D> <ModelVisual3D.Content> <AmbientLight Color="White" /> </ModelVisual3D.Content> </ModelVisual3D> <Viewport2DVisual3D RenderOptions.CachingHint="Cache" RenderOptions.CacheInvalidationThresholdMaximum="2" RenderOptions.CacheInvalidationThresholdMinimum="0.5"/> </Viewport3D> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>

• Defining a ContextMenu in a DataGridRow style

  - by Brent

  I'm trying to clean up some of my xaml in my views by moving a lot of the DataGrid styles into a ResourceDictionary. One of the things I'd like to move is the ContextMenu that is bound to some commands in the ViewModel. However, when I move the context menu to the ResourceDictionary, the commands are are never firing anymore, and I can't figure out why. I've defined the ContextMenu in the DataGridRow style so that when the user right clicks on the columnheader, no ContextMenu is shown... it will only be shown they right click on a row. Am I doing something wrong here? FYI I'm using VS 2010 RTM if that makes a difference. <Style x:Key="DataGridRowStyle" TargetType="{x:Type DataGridRow}"> <Setter Property="Height" Value="20"/> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Header="New" Command="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}, Path=DataContext.NewCommand}"> <MenuItem.Icon> <Image Source="/Images/DocumentWhite(32N).png" Width="16" Height="16"/> </MenuItem.Icon> </MenuItem> <MenuItem Header="Open" Command="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}, Path=DataContext.OpenCommand}"> <MenuItem.Icon> <Image Source="/Images/FolderOpenYellow(32N).png" Width="16" Height="16"/> </MenuItem.Icon> </MenuItem> <MenuItem Header="Delete" Command="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}, Path=DataContext.DeleteCommand}"> <MenuItem.Icon> <Image Source="/Images/Delete(32N).png" Width="16" Height="16"/> </MenuItem.Icon> </MenuItem> </ContextMenu> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" Value="{StaticResource hoverGradient}"/> </Trigger> <Trigger Property="IsSelected" Value="True"> <Setter Property="Background" Value="{StaticResource BtnOverFill}"/> </Trigger> </Style.Triggers> </Style>

• .NET Backgroundworker - Is there no way to let exceptions pass back normally to main thread?

  - by Greg

  Hi, QUESTION: Re use of .NET Backgroundworker, is there not a way to let exceptions pass back normally to main thread? BACKGROUND: Currently in my WinForms application I have generic exception handle that goes along the lines of, if (a) a custom app exception then present to user, but don't exit program, and (b) if other exception then present and then exit application The above is nice as I can just throw the appropriate exception anywhere in the application and the presentation/handling is handled generically
