  Hi all, I am having intermittent issues saving the response HTML in HtmlUnit.

• Using Ninject 2.0 with ASP .Net 3.5

  - by GK

  Hi, I am trying to use Ninject 2.0 with Asp .Net 3.5 web application. Following are the DLLS and it's versions I am using. Ninject.dll - v2.0.0.0 Ninject.Extensions.Logging.dll v2.0.0.0 Ninject.Web.dll v1.0.0.0 In my global.ascx.cs I have following method. protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(); kernel.Bind<IDataAccess>().To<DataAccessEntBlock>().InSingletonScope(); return kernel; } When I run the application I get following error. Error activating ILoggerFactory No matching bindings are available, and the type is not self-bindable. Activation path: 1) Request for ILoggerFactory Suggestions: 1) Ensure that you have defined a binding for ILoggerFactory. 2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. 3) Ensure you have not accidentally created more than one kernel. 4) If you are using automatic module loading, ensure the search path and filters are correct. I am not understanding even though I am not trying to register Logger, it seems it is trying to create it's own. How can I resolve this error ? Do I have to use any of the Ninject's extension Logger ? Thanks GK

• NSFileManager works fine on simulator but not on device

  - by Jenicek

  Hi, I have problem creating directories and files with NSFileManager on the iPhone device. My code, shown below, works fine on the simulator, but not on the device, could you please help me? Gimme some directions where the problem may be, thanks for every reply.. I'm first creating directories this way: NSFileManager *fileMgr = [NSFileManager defaultManager]; NSArray *arPaths = NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask, YES); NSString *appPath = [[NSString alloc] init]; appPath = [arPaths objectAtIndex:0]; strDownloadsDir = [[NSString alloc] init]; strDownloadsDir = [[appPath stringByAppendingPathComponent:@"/Other"] copy]; if(![fileMgr fileExistsAtPath:strDownloadsDir]) [fileMgr createDirectoryAtPath:strDownloadsDir attributes:nil]; and then I'm trying to create new file in this directory this way: NSString *filePath = [strDownloadsDir stringByAppendingPathComponent:strDlFileName]; //Test whether this file exists, if not, create it NSLog(@"%@", filePath); if(![fileMgr fileExistsAtPath:filePath]) { if([fileMgr createFileAtPath:filePath contents:nil attributes:nil]) NSLog(@"Creating new file at path %@", filePath); else NSLog(@"Failed to create new file."); } It seems that there's something wrong with whole NSFileManager, because when I'm using fileExistAtPath with a path given by this NSArray *arPaths = NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask, YES); NSString *appPath = [[NSString alloc] init]; appPath = [arPaths objectAtIndex:0]; it is not working too, I tried to change directory to NSDocumentsDirectory but it did not help

• ListView + MultipleSelect + MVVM = ?

  - by Dave

  If I were to say "the heck with it!", I could just give my ListView with SelectionMode="Multiple" a name, and be able to get all of the selected items very easily. But I'm trying to stick to MVVM as much as possible, and I want to somehow databind to an ObservableCollection that holds the value from the Name column for each selected item. How in the world do you do this? Single selection is simple, but the multi selection solution is not obvious to me with my current WPF / MVVM knowledge. I read this question on SO, and while it does give me some good insight, I don't know how to add the necessary binding to a row, because I am using a ListView with a GridView as its View, not a ListBox. Here's what my XAML basically looks like: <ListView DockPanel.Dock="Top" ItemsSource="{Binding ClientPreview}" SelectionMode="Multiple"> <ListView.View> <GridView AllowsColumnReorder="False"> <GridViewColumn Header="Name"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Name}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Address"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Address}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> It sounds like the right thing to do is to databind each row's IsSelected property to each object stored in the ObservableCollection I'm databinding to. I just haven't figured out how to do this.

• How do I use Powershell to print a list of hyperlinks that appear in a Word document?

  - by dwwilson66

  I asked this question last week, and my script cannot find any hyperlinks to change. Now I'm backing up and trying to simply open a single document and list the hyperlinks within. I've verified that the document includes hyperlinks to a number of anchors in the same document, and two hyperlinks to documents in the same directory. However, either Powershell isn't finding links in the doc or I'm outputting the list to the console improperly. Here's my bare-bones code $word = New-Object -ComObject Word.Application $doc ="R:\path\Reporting_Emergency_Or_Hazardous_Situation_-_BC_CC.doc" $hyperlinks = @($doc.Hyperlinks) $hyperlinks $word.quit() or, for line 4 Write-Host $hyperlinks or, again for line 4 $hyperlinks | % {Write-Host $_.address} No errors, just blank results. Not even an object reference to the $hyperlinks array. When I modify line 4 to % $address in $hyperlinks { Write-Host $._address } I get the following error...but it's unclear if I'm trying to read a null array? or if the value is blank. ForEach-Object : Cannot bind parameter 'Process'. Cannot convert the "in" value of type "System.String" to type "System.Management.Automation.ScriptBlock". At F:\path\HyperLinkScrub.ps1:46 char:2 + % <<<< $address in $hyperlinks { + CategoryInfo : InvalidArgument: (:) [ForEach-Object], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.ForEachObjectCommand What am I missing here? I've verified that the Word doc has hyperlinks, and ultimately, I'm trying to diagnose if my script isn't looking for them properly, or if I'm not outputting them to the console properly.

• HRESULT of 0x806D0005 from Microsoft's Dia2Lib

  - by Aeolien

  I'm trying to read a PDB file into a C# application. When I call loadDataFromPdb or loadAndValidateDataFromPdb with a file that I know exists, I get an HRESULT of 0x806D0005. Unfortunately, I have no idea what that means. I have the list of possible results [here](http://msdn.microsoft.com/en-us/library/2008hf0e(v=VS.80).aspx) but I'm afraid I can't conclusively determine the problem. Does anybody know what I'm doing wrong? Or at least a method of checking what that corresponds to? Exception: System.Runtime.InteropServices.COMException (0x806D0005): Exception from HRESULT: 0x806D0005 at Dia2Lib.DiaSourceClass.loadDataFromPdb(String pdbPath) Code Sample: public static void LoadSymbolsForModule(uint baseAddress, uint size, uint timeStamp, DM_PDB_SIGNATURE signature) { IDiaDataSource m_source = new DiaSourceClass(); //m_source.loadAndValidateDataFromPdb(signature.path, ref signature.guid, 0, signature.age); m_source.loadDataFromPdb(signature.path); IDiaSession m_session; m_source.openSession(out m_session); m_session.loadAddress = baseAddress; modules.Add(new Module(baseAddress, size, m_session)); } Thanks in advance, guys. This problem has been killing me all day.

• Intellij Javafx artifact - how do you make it?

  - by Louis Sayers

  I've been trying all day to turn my javafx application into a jar file. I'm using Java 1.7 update 7. Oracle has some information, but it just seems scattered all over the place. Intellij is almost doing the job, but I get the following error: java.lang.NoClassDefFoundError: javafx/application/Application Which seems to say that I need to tell java where the jfxrt.jar is... If I add this jar to my classpath info for the manifest build in intellij - ctrl+shift+alt+s - Artifacts - Output Layout tab - Class Path, then I get another error: Could not find or load main class com.downloadpinterest.code.Main It seems strange to have to include jfxrt.jar in my class path though... I've tried to create an ant script as well, but I feel like IntelliJ is 90% of the way there - and I just need a bit of help to figure out why I need to include jfxrt.jar, and why my Main class isn't being found (I'm guessing I need to add it to the classpath somehow?). Could anyone clue me up as to what is happening? I had a basic gui before which worked fine, but JavaFX seems to be making life complicated!

• ASP.NET Create zip file for download: the compressed zipped folder is invalid or corrupted

  - by Jason Braswell

  string fileName = "test.zip"; string path = "c:\\temp\\"; string fullPath = path + fileName; FileInfo file = new FileInfo(fullPath); Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); Response.Buffer = true; Response.AppendHeader("content-disposition", "attachment; filename=" + fileName ); Response.AppendHeader("content-length", file.Length.ToString()); Response.ContentType = "application/x-compressed"; Response.TransmitFile(fullPath); Response.Flush(); Response.End(); The actual zip file c:\temp\test.zip is good, valid, whatever you want to call it. When I navigate to the directory c:\temp\ and double-click on the test.zip file; it opens right up. My problem seems only to be with the download. The code above executes without any issue. A file download dialog is presented. I can chose to either save or open. If I try to open the file from the dialog, or save it and then open it. I get the following dialog message: The Compressed (zipped) Folder is invalid or corrupted. For Response.ContentType I've tried: application/x-compressed application/x-zip-compressed application/x-gzip-compresse application/octet-stream application/zip The zip file is being created with some prior code (that I'm sure is working fine due to my ability to open the created file directly) using: Ionic.zip http://www.codeplex.com/DotNetZip

• WPF binding to ComboBox SelectedItem when reference not in ItemsSource.

  - by juharr

  I'm binding the PageMediaSize collection of a PrintQueue to the ItemSource of a ComboBox (This works fine). Then I'm binding the SelectedItem of the ComboBox to the DefaultPrintTicket.PageMediaSize of the PrintQueue. While this will set the selected value to the DefaultPrintTicket.PageMediaSize just fine it does not set the initially selected value of the ComboBox to the initial value of DefaultPrintTicket.PageMediaSize This is because the DefaultPrintTicket.PageMediaSize reference does not match any of the references in the collection. However I don't want it to compare the objects by reference, but instead by value, but PageMediaSize does not override Equals (and I have no control over it). What I'd really like to do is setup a IComparable for the ComboBox to use, but I don't see any way to do that. I've tried to use a Converter, but I would need more than the value and I couldn't figured out how to pass the collection to the ConverterProperty. Any ideas on how to handle this problem. Here's my xaml <ComboBox x:Name="PaperSizeComboBox" ItemsSource="{Binding ElementName=PrintersComboBox, Path=SelectedItem, Converter={StaticResource printQueueToPageSizesConverter}}" SelectedItem="{Binding ElementName=PrintersComboBox, Path=SelectedItem.DefaultPrintTicket.PageMediaSize}" DisplayMemberPath="PageMediaSizeName" Height="22" Margin="120,76,15,0" VerticalAlignment="Top"/> And the code for the converter that gets the PageMediaSize collection public class PrintQueueToPageSizesConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return value == null ? null : ((PrintQueue)value).GetPrintCapabilities().PageMediaSizeCapability; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } }

• Silverlight - Access the Layout Grid's DataContext in a DataGrid CellTemplate's DataTemplate?

  - by Sudeep

  Hi, I am using Silverlight 3 to develop an application. In my app, I have a layout Grid (named "LayoutGrid") in which I have a DataGrid (named "PART_datagrid") with DataGridTemplateColumns. The LayoutGrid is set a DataContext in which there is a Ladders list as a property. This Ladders list is set as the ItemsSource for the PART_datagrid. <Grid x:Name="LayoutRoot"> <DataGrid x:Name="PART_datagrid" ItemsSource="{Binding Ladders}"> ... <DataGridTemplateColumn> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <Button Name="DeleteLadder" Click.Command="{Binding ElementName=LayoutRoot, Path=DataContext.DeleteLadderCommand}" /> Now in one of the DataGridTemplateColumns I have a button which should invoke a Command thats present in the LayoutGrid's DataContext. So I tried Element-To-Element binding on my DataTemplate button as follows <Button Name="DeleteLadder" Click.Command="{Binding ElementName=LayoutRoot, Path=DataContext.DeleteLadderCommand}" /> But this does not seem to work. What I want to achieve is to handle the event of deletion of a DataGrid row at the parent DataContext level using the command. Can someone pls suggest how do I proceed on this? Thanks in advance...

• How to scrape a _private_ google group?

  - by John

  Hi there, I'd like to scrape the discussion list of a private google group. It's a multi-page list and I might have to this later again so scripting sounds like the way to go. Since this is a private group, I need to login in my google account first. Unfortunately I can't manage to login using wget or ruby Net::HTTP. Surprisingly google groups is not accessible with the Client Login interface, so all the code samples are useless. My ruby script is embedded at the end of the post. The response to the authentication query is a 200-OK but no cookies in the response headers and the body contains the message "Your browser's cookie functionality is turned off. Please turn it on." I got the same output with wget. See the bash script at the end of this message. I don't know how to workaround this. am I missing something? Any idea? Thanks in advance. John Here is the ruby script: # a ruby script require 'net/https' http = Net::HTTP.new('www.google.com', 443) http.use_ssl = true path = '/accounts/ServiceLoginAuth' email='[email protected]' password='topsecret' # form inputs from the login page data = "Email=#{email}&Passwd=#{password}&dsh=7379491738180116079&GALX=irvvmW0Z-zI" headers = { 'Content-Type' => 'application/x-www-form-urlencoded', 'user-agent' => "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/6.0"} # Post the request and print out the response to retrieve our authentication token resp, data = http.post(path, data, headers) puts resp resp.each {|h, v| puts h+'='+v} #warning: peer certificate won't be verified in this SSL session Here is the bash script: # A bash script for wget CMD="" CMD="$CMD --keep-session-cookies --save-cookies cookies.tmp" CMD="$CMD --no-check-certificate" CMD="$CMD --post-data='[email protected]&Passwd=topsecret&dsh=-8408553335275857936&GALX=irvvmW0Z-zI'" CMD="$CMD --user-agent='Mozilla'" CMD="$CMD https://www.google.com/accounts/ServiceLoginAuth" echo $CMD wget $CMD wget --load-cookies="cookies.tmp" http://groups.google.com/group/mygroup/topics?tsc=2

• Dynamic Programming Recursion and a sprinkle of Memoization

  - by Auburnate

  I have this massive array of ints from 0-4 in this triangle. I am trying to learn dynamic programming with Ruby and would like some assistance in calculating the number of paths in the triangle that meet three criterion: You must start at one of the zero points in the row with 70 elements. Your path can be directly above you one row (if there is a number directly above) or one row up heading diagonal to the left. One of these options is always available The sum of the path you take to get to the zero on the first row must add up to 140. Example, start at the second zero in the bottom row. You can move directly up to the one or diagonal left to the 4. In either case, the number you arrive at must be added to the running count of all the numbers you have visited. From the 1 you can travel to a 2 (running sum = 3) directly above or to the 0 (running sum = 1) diagonal to the left. 0 41 302 2413 13024 024130 4130241 30241302 241302413 1302413024 02413024130 413024130241 3024130241302 24130241302413 130241302413024 0241302413024130 41302413024130241 302413024130241302 2413024130241302413 13024130241302413024 024130241302413024130 4130241302413024130241 30241302413024130241302 241302413024130241302413 1302413024130241302413024 02413024130241302413024130 413024130241302413024130241 3024130241302413024130241302 24130241302413024130241302413 130241302413024130241302413024 0241302413024130241302413024130 41302413024130241302413024130241 302413024130241302413024130241302 2413024130241302413024130241302413 13024130241302413024130241302413024 024130241302413024130241302413024130 4130241302413024130241302413024130241 30241302413024130241302413024130241302 241302413024130241302413024130241302413 1302413024130241302413024130241302413024 02413024130241302413024130241302413024130 413024130241302413024130241302413024130241 3024130241302413024130241302413024130241302 24130241302413024130241302413024130241302413 130241302413024130241302413024130241302413024 0241302413024130241302413024130241302413024130 41302413024130241302413024130241302413024130241 302413024130241302413024130241302413024130241302 2413024130241302413024130241302413024130241302413 13024130241302413024130241302413024130241302413024 024130241302413024130241302413024130241302413024130 4130241302413024130241302413024130241302413024130241 30241302413024130241302413024130241302413024130241302 241302413024130241302413024130241302413024130241302413 1302413024130241302413024130241302413024130241302413024 02413024130241302413024130241302413024130241302413024130 413024130241302413024130241302413024130241302413024130241 3024130241302413024130241302413024130241302413024130241302 24130241302413024130241302413024130241302413024130241302413 130241302413024130241302413024130241302413024130241302413024 0241302413024130241302413024130241302413024130241302413024130 41302413024130241302413024130241302413024130241302413024130241 302413024130241302413024130241302413024130241302413024130241302 2413024130241302413024130241302413024130241302413024130241302413 13024130241302413024130241302413024130241302413024130241302413024 024130241302413024130241302413024130241302413024130241302413024130 4130241302413024130241302413024130241302413024130241302413024130241 30241302413024130241302413024130241302413024130241302413024130241302 241302413024130241302413024130241302413024130241302413024130241302413 1302413024130241302413024130241302413024130241302413024130241302413024 02413024130241302413024130241302413024130241302413024130241302413024130

• UIImagePickerController Save to Disk then Load to UIImageView

  - by Harley Gagrow

  Hi, I have a UIImagePickerController that saves the image to disk as a png. When I try to load the PNG and set a UIImageView's imageView.image to the file, it is not displaying. Here is my code: (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; NSData *imageData = UIImagePNGRepresentation(image); // Create a file name for the image NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setTimeStyle:NSDateFormatterShortStyle]; [dateFormatter setDateStyle:NSDateFormatterShortStyle]; NSString *imageName = [NSString stringWithFormat:@"photo-%@.png", [dateFormatter stringFromDate:[NSDate date]]]; [dateFormatter release]; // Find the path to the documents directory NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; // Now we get the full path to the file NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName]; // Write out the data. [imageData writeToFile:fullPathToFile atomically:NO]; // Set the managedObject's imageLocation attribute and save the managed object context [self.managedObject setValue:fullPathToFile forKey:@"imageLocation"]; NSError *error = nil; [[self.managedObject managedObjectContext] save:&error]; [self dismissModalViewControllerAnimated:YES]; } Then here is how I try to load it: self.imageView.backgroundColor = [UIColor lightGrayColor]; self.imageView.frame = CGRectMake(10, 10, 72, 72); if ([self.managedObject valueForKey:@"imageLocation"] != nil) { NSLog(@"Trying to load the imageView with: %@", [self.managedObject valueForKey:@"imageLocation"]); UIImage *image = [[UIImage alloc] initWithContentsOfFile:[self.managedObject valueForKey:@"imageLocation"]]; self.imageView.image = image; } else { self.imageView.image = [UIImage imageNamed:@"no_picture_taken.png"]; } I get the message that it's trying to load the imageView in the debugger, but the image is never displayed in the imageView. Can anyone tell me what I've got wrong here? Thanks a bunch.

• MVVM Binding in Silverlight3 ItemsControl to get the parent controls DataContext

  - by BigTundra

  I have the following ItemsControl in Silverlight 3. <ItemsControl ItemsSource="{Binding ValueCollectionList}"> <ItemsControl.ItemTemplate> <DataTemplate> <Button x:Name="MyBtn" Height="40" Content="{Binding Name}" Tag="{Binding Value}" cmd:ButtonBaseExtensions.Command="{Binding ElementName=LayoutRoot, Path=ButtonCommand}" cmd:ButtonBaseExtensions.CommandParameter="{Binding ElementName=MyBtn, Path=Tag}"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> The Problem is that I have the ItemsControl bound to the Collection in my ViewModel, but I need the button to trigger a command on the ViewModel which is of course not Available in the DataContext of the button since it only contains the collection. I can make the command fire by setting my ViewModel as a Resource and then binding to it as a StaticResource, but I want to know why the element to element binding won't work in this scenario. I would prefer not to use the StaticResource binding because that requires the default constructor on the ViewModel and so I can't inject my data easily.

• Downloading attachments from Exchange with WebDAV

  - by arturito

  Hi there! I've been trying to retrive attachment from message in Exchange server using WebDAV.I don't know which version of Exchange the company is running. I'can successfully read messages and retrive list of attachments. However I am failing to save attachments. In both cases errors is: "The remote server returned an error: <403 Forbidden. Any idea what I'm doing wrong?

• How do I bind list items to an Accordian control from the Silverlight 3 Toolkit?

  - by Blanthor

  I have a list of objects in a model public class AccordianModel { public List<AccordianItem> Items { get; set; } public AccordianModel() { Items = new List<AccordianItem> { new AccordianItem() {Title = "Monkey", ImageUri = "Images/monkey.jpg"}, new AccordianItem() {Title = "Cow", ImageUri = "Images/cow.jpg"}, }; } } I want to show the image in the background image of AccordianItems If I hard code it, it looks like this... <layoutToolkit:AccordionItem x:Name="Item2" Header="Item 2" Margin="0,0,10,0" AccordionButtonStyle="{StaticResource AccordionButtonStyle1}" ExpandableContentControlStyle="{StaticResource ExpandableContentControlStyle1}" HeaderTemplate="{StaticResource DataTemplate1}" BorderBrush="{x:Null}" ContentTemplate="{StaticResource CarouselContentTemplate}"> <layoutToolkit:AccordionItem.Background> <ImageBrush ImageSource="Images/cow.jpg" Stretch="None"/> </layoutToolkit:AccordionItem.Background> </layoutToolkit:AccordionItem> When I try it with a binding like <ImageBrush ImageSource="{Binding Path={StaticResource MyContentTemplate.ImageUri}}" Stretch="None"/> or if I try it with <ImageBrush ImageSource="{Binding Path=Items[0].ImageUri}" Stretch="None"/> , it throws XamlParseException. I haven't seen enough Silverlight yet and I cannot find a close enough example that it makes sense to me.

• Styling columns based on DataGridTemplateColumn in a WPF DataGrid

  - by nareshbhatia

  I am using a WPF DataGrid where one of the columns has a requirement to show an "Edit" hyperlink if the row is editable - this is indicated by a boolean flag in the backing model for the row. I was able to achieve this using a DataGridTemplateColumn - no problems. However an additional requirement on the entire row is not to show any highlights when the row is selected (this is a blue background by default). I have been able to achieve this on other columns by defining the DataGridCell style with a transparent background, e.g. <DataGridTextColumn Header="Id" Binding="{Binding Path=Id}" HeaderStyle="{StaticResource DataGridColumnHeaderStyle}" CellStyle="{StaticResource DataGridCellStyle}" /> where DataGridCellStyle is defined as follows: <Style x:Key="DataGridCellStyle" TargetType="{x:Type DataGridCell}"> <Setter Property="Background" Value="Transparent" /> ... </Style> However the column in question, a DataGridTemplateColumn, does not offer a "CellStyle" attribute which I can use for turning off selection highlights. So my question is how to set the cell style when using a DataGridTemplateColumn? Here's my implementation of the column which satisfies the first requirement (i.e. showing an "Edit" hyperlink if the row is editable): <DataGridTemplateColumn Header="Actions" HeaderStyle="{StaticResource CenterAlignedColumnHeaderStyle}"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Visibility="{Binding Path=Editable, Converter={StaticResource convVisibility}}" Style="{StaticResource CenterAlignedElementStyle}"> <Hyperlink Command="..." CommandParameter="{Binding}"> <TextBlock Text="Edit" /> </Hyperlink> </TextBlock> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> Thanks.

• How can I get PowerShell Added-Types to use Added Types

  - by Scott Weinstein

  I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

• JMeter Stress testing

  - by mcondiff

  MAMP server hosting a Joomla instance. I'd like to hear the community's thoughts on the best way to stress test the server and find it's breaking point on concurrent users etc. Currently I have setup a test plan which I have going to the home page, grabbing the index.php, css, js and all images and have run tests on 1 to 100 users and a varying number of loops. What I'd like to know is how do I determine at what number of concurrent requests or looping requests is a good way to gauge if my server can handle the proposed increase in traffic? What is a good KB/sec, Throughput, Average, Max, Min via the Aggregate Report and at what number of threads/loops etc? I have googled and have not found immediate answers to these questions and thought to come here. More or less I have just used this http://jakarta.apache.org/jmeter/usermanual/jmeter_proxy_step_by_step.pdf to guide me and then I have been winging it in terms of Thread and Loop numbers. Any light shed on these subject would be much appreciated.

• The best way to package iPhone/iPad static libraries?

  - by Derek Clarkson

  Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

• How to propertly reference a namespace for Microsoft.Sdc.Tasks.XmlFile.GetValue

  - by æther

  Hi, i want to use MSBuild to insert a custom xml element into web.config. After looking up online, i found such solution: 1) Store element in the .build file in projectextensions <ProjectExtensions> <CustomElement name="CustomElementName"> ... </CustomElement> </ProjectExtensions> 2) Retrieve the element with GetValue <Target name="ModifyConfig"> <XmlFile.GetValue Path="$(MSBuildProjectFullPath)" XPath="Project/ProjectExtensions/CustomElement[@name='CustomElementName']"> <Output TaskParameter="Value" PropertyName="CustomElementProperty"/> </XmlFile.GetValue> </Target> This will not work as i need to reference a namespace the .build project is using for it to find the needed element (checked the .build file with XPath Visualizer). So, i look up for a further solution and come to this: <ItemGroup> <XmlNamespace Include="MSBuild"> <Prefix>msb</Prefix> <Uri>http://schemas.microsoft.com/developer/msbuild/2003</Uri> </XmlNamespace> </ItemGroup> <Target name="ModifyConfig"> <XmlFile.GetValue Path="$(MSBuildProjectFullPath)" Namespaces="$(XmlNamespace)" XPath="/msb:Project/msb:ProjectExtensions/msb:CustomElement[@name='CustomElementName']" > <Output TaskParameter="Value" PropertyName="CustomElementProperty"/> </XmlFile.GetValue> </Target> But for some reason namespace is not recognized - MSBuild reports the following error: C:...\mybuild.build(53,9): error : A task error has occured. C:...\mybuild.build(53,9): error : Message = Namespace prefix 'msb' is not defined. I tried some variations of referencing it differently but none work, and there is not much about propertly referencing those namespaces online also. Can you tell me what am i doing wrong and how to do it propertly?
