• How do I get MSDeploy to skip specific folders and file types in folders as CCNet task

  - by Simon Martin

  I want MSDeploy to skip specific folders and file types within other folders when using sync. Currently I'm using CCNet to call MSDeploy with the sync verb to take websites from a build to a staging server. Because there are files on the destination that are created by the application / user uploaded files etc, I need to exclude specific folders from being deleted on the destination. Also there are manifest files created by the site that need to remain on the destination. At the moment I've used -enableRule:DoNotDeleteRule but that leaves stale files on the destination. <exec> <executable>$(MsDeploy)</executable> <baseDirectory>$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\</baseDirectory> <buildArgs>-verb:sync -source:iisApp="$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\" -dest:iisApp="$(website)/$(websiteFolder)" -enableRule:DoNotDeleteRule</buildArgs> <buildTimeoutSeconds>600</buildTimeoutSeconds> <successExitCodes>0,1,2</successExitCodes> </exec> I have tried to use the skip operation but run into problems. Initially I dropped the DoNotDeleteRule and replaced it with (multiple) skip <exec> <executable>$(MsDeploy)</executable> <baseDirectory>$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\</baseDirectory> <buildArgs>-verb:sync -source:iisApp="$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\" -dest:iisApp="$(website)/$(websiteFolder)" -skip:objectName=dirPath,absolutePath="assets" -skip:objectName=dirPath,absolutePath="survey" -skip:objectName=dirPath,absolutePath="completion/custom/complete*.aspx" -skip:objectName=dirPath,absolutePath="completion/custom/surveylist*.manifest" -skip:objectName=dirPath,absolutePath="content/scorecardsupport" -skip:objectName=dirPath,absolutePath="Desktop/docs" -skip:objectName=dirPath,absolutePath="_TempImageFiles"</buildArgs> <buildTimeoutSeconds>600</buildTimeoutSeconds> <successExitCodes>0,1,2</successExitCodes> </exec> But this results in the following: Error: Source (iisApp) and destination (contentPath) are not compatible for the given operation. Error count: 1. So I changed from iisApp to contentPath and instead of dirPath,absolutePath just Directory like this: <exec> <executable>$(MsDeploy)</executable> <baseDirectory>$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\</baseDirectory> <buildArgs>-verb:sync -source:contentPath="$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\" -dest:contentPath="$(website)/$(websiteFolder)" -skip:Directory="assets" -skip:Directory="survey" -skip:Directory="content/scorecardsupport" -skip:Directory="Desktop/docs" -skip:Directory="_TempImageFiles"</buildArgs> <buildTimeoutSeconds>600</buildTimeoutSeconds> <successExitCodes>0,1,2</successExitCodes> </exec> and this gives me an error: Illegal characters in path: < buildresults Info: Adding MSDeploy.contentPath (MSDeploy.contentPath). Info: Adding contentPath (C:\WWWRoot\MySite -skip:Directory=assets -skip:Directory=survey -skip:Directory=content/scorecardsupport -skip:Directory=Desktop/docs -skip:Directory=_TempImageFiles). Info: Adding dirPath (C:\WWWRoot\MySite -skip:Directory=assets -skip:Directory=survey -skip:Directory=content/scorecardsupport -skip:Directory=Desktop/docs -skip:Directory=_TempImageFiles). < /buildresults < buildresults Error: Illegal characters in path. Error count: 1. < /buildresults So I need to know how to configure this task so the folders referenced do not have their contents deleted in a sync and that that *.manifest and *.aspx files in the completion/custom folders are also skipped.

• A queue in C using structs and dynamic memory allocation (linked list)

  - by Martin Pugh

  I am tasked with making a queue data structure in C, as a linked list. Our lecturer gave us a large amount of code to implement a stack, but we have to adapt it to create a queue. The code our lecturer gave us ends up not compiling and segfaulting at the exact same point as the code I wrote for the queue. I'm very new to structs, malloc and C in general, so there could be something painfully obvious I've overlooked. Here is the code I am using: #include <stdio.h> #include <stdlib.h> struct node{ int data; //contains the actual data struct node *prev; //pointer to previous node (Closer to front) struct node *next; //pointer to next node (Closer to back) }; typedef struct node *Nodepointer; struct queue{ Nodepointer front; Nodepointer back; }; typedef struct queue *Queuepointer; main(){ Queuepointer myqueue; //create a queue called myqueue init(myqueue); //initialise the queue Nodepointer new = (Nodepointer)malloc(sizeof(struct node)); myqueue->front = new; } int init(Queuepointer q){ q = (Queuepointer)malloc(sizeof(struct queue)); q->front = NULL; q->back = NULL; } The idea is that the queue struct 'contains' the first and last nodes in a queue, and when a node is created, myqueue is updated. However, I cannot even get to that part (pop and push are written but omitted for brevity). The code is segfaulting at the line myqueue->front = new; with the following gdb output: Program received signal SIGSEGV, Segmentation fault. 0x08048401 in main () at queue.c:27 27 myqueue->front = new; Any idea what I'm doing wrong?

• Can only "agents" build and submit Applications to Apple?

  - by Martin

  I'm afraid I know the answer to this but I'll ask on the longshot chance that I'm wrong: I've been doing some freelance work creating an iPhone application for a company. They've created their own developer account and added me as an team member with "admin" rights. That seems to be the highest assignable rights (with the only higher level being "agent" and belonging only to whoever signed up for the account). Yet, I don't have an option under the provisioning portal to create a distribution certificate or profile. Is there any way to create these myself without having to ask my client for their primary login? They're not particulary tech savy so it would be difficult to walk them through the process to create the necessary certificates (and would require me giving them a certificate request from my computer, etc. etc.). But it seems like there should be some way to create a distribution build without "agent" rights, right? Could Apple seriously expect only one person from a company to do all the building and uploading of apps to the store?

• Is is possible to programmatically change the resourceProviderFactoryType?

  - by Robert Massa

  I have a custom implementation of IResourceProvider and ResourceProviderFactory. Now the default way of making sure ASP.NET uses these custom types is to use the web.config and specify the factory like so: <globalization resourceProviderFactoryType="Product.Globalization.TranslationResourceProviderFactory" /> This works perfectly, except that in my resource provider I need database access. I want to use my IoC-container(Ninject) to inject the repositories needed to access this data into the CustomResourceProvider. But how am I going to do this? I have no control over the instantiation of the factory, so the factory can't get a reference to my IoC. Is there any way to register a custom provider programmatically, in for example the Global.asax?

• Android MediaStore insertVideo

  - by Robert

  So our app has the option to take either a picture or a video. If the user takes a picture, we can use the MediaStore.Images.Media.insertImage function to add the new image (via a filepath) to the phone's gallery and generate a content:// style URI. Is there a similar process for a captured video, given that we only have it's filepath?

• FoxPro to C#: What best method between ODBC, OLE DB or another?

  - by Martin Labelle

  We need to read data from FoxPro 8 with C#. I'm gonna do some operations, and will push some of thoses data to an SQL Server database. We are not sure what's best method to read those data. I saw OLE DB and ODBC; what's best? REQUIRMENTS: The export program will run each night, but my company runs 24h a day. The DBF could sometimes be huge. We DON'T need to modify data. Our system, wich use FoxPro, is quite unstable: I need to find a way that ABSOLUTELY do not corrupt data, and, ideally, do not lock DBF files while reading. Speed is a minor requirement: it must be quick, but requirement #4 is most important.

• Asp.net MVC error with custom HttpModule

  - by Robert Koritnik

  I have a custom authentication HttpModule that is pretty strait forward. But I want it to run only for managed requests (and not for static ones). Asp.net MVC automatically adds configuration section for IIS7 web server: <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <remove name="ScriptModule" /> <remove name="UrlRoutingModule" /> <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule,..." /> <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule,..." /> </modules> <handlers> ... </handlers> </system.webServer> When I add my own module I also set its preCondition="managedHandler", but since there's runAllManagedModulesForAllRequests="true" on parent <module> element my preCondition is ignored by design (as I read on MSDN). When I try to set though: <modules runAllManagedModulesForAllRequests="false"> I get this error: [image no longer valid] What else (which other module) do I have to set in web.config to make it work with this setting: <modules runAllManagedModulesForAllRequests="false">

• Best approach, Dynamic OpenXML in T-SQL

  - by Martin Ongtangco

  hello, i'm storing XML values to an entry in my database. Originally, i extract the xml datatype to my business logic then fill the XML data into a DataSet. I want to improve this process by loading the XML right into the T-SQL. Instead of getting the xml as string then converting it on the BL. My issue is this: each xml entry is dynamic, meaning it can be any column created by the user. I tried using this approach, but it's giving me an error: CREATE PROCEDURE spXMLtoDataSet @id uniqueidentifier, @columns varchar(max) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; DECLARE @name varchar(300); DECLARE @i int; DECLARE @xmlData xml; (SELECT @xmlData = data, @name = name FROM XmlTABLES WHERE (tableID = ISNULL(@id, tableID))); EXEC sp_xml_preparedocument @i OUTPUT, @xmlData DECLARE @tag varchar(1000); SET @tag = '/NewDataSet/' + @name; DECLARE @statement varchar(max) SET @statement = 'SELECT * FROM OpenXML(@i, @tag, 2) WITH (' + @columns + ')'; EXEC (@statement); EXEC sp_xml_removedocument @i END where i pass a dynamically written @columns. For example: spXMLtoDataSet 'bda32dd7-0439-4f97-bc96-50cdacbb1518', 'ID int, TypeOfAccident int, Major bit, Number_of_Persons int, Notes varchar(max)' but it kept on throwing me this exception: Msg 137, Level 15, State 2, Line 1 Must declare the scalar variable "@i". Msg 319, Level 15, State 1, Line 1 Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

• Sharepoint Foundation 2010 installation problems

  - by Robert Koritnik

  I'm having problems installing development machine for Sharepoint (Foundation) 2010. This is what I did so far on the same machine: Installed a clean Windows 7 x64 with 4GB of RAM without being part of any domain. Just a simple standalone machine. Enabled IIS related features as described here except IIS6 related ones (two of them) Installed SQL Server 2008 R2 Development Edition (DB Engine and Writer being enabled but not SQL Agent) Installed Visual Studio 2010 Premium Started installing Sharepoint Foundation 2010 with first extracting files, changing config to enable Windows 7 installation and then installed it as Server Farm (then Complete) to avoid installing SQL Express. Created a separate SPF_CONFIG local user with Logon on as a service right. Opened SPF Management Shell and run New-SPConfigurationDatabase so I am able to use a non-domain username (SPF_CONFIG that I created in the previous step) But all I get is this: The outcome after this error is: Database Sharepoint2010Config is created User SPF_CONFIG is added to SQL Server and attached to this newly created database as dbowner and checking SQL server security logins this user has following rights: dbcreator securityadmin public

• How is thread synchronization implemented, at the assembly language level?

  - by Martin

  While I'm familiar with concurrent programming concepts such as mutexes and semaphores, I have never understood how they are implemented at the assembly language level. I imagine there being a set of memory "flags" saying: lock A is held by thread 1 lock B is held by thread 3 lock C is not held by any thread etc But how is access to these flags synchronized between threads? Something like this naive example would only create a race condition: mov edx, [myThreadId] wait: cmp [lock], 0 jne wait mov [lock], edx ; I wanted an exclusive lock but the above ; three instructions are not an atomic operation :(

• Java resource as file

  - by Martin Riedel

  Is there a way in Java to construct a File instance on a resource retrieved from a jar through the classloader? My application uses some files from the jar (default) or from a filesystem directory specified at runtime (user input). I'm looking for a consistent way of a) loading these files as a stream b) listing the files in the user-defined directory or the directory in the jar respectively Edit: Apparently, the ideal approach would be to stay away from java.io.File altogether. Is there a way to load a directory from the classpath and list its contents (files/entities contained in it)?

• a facebook app question

  - by Robert

  I have written a small app and put it on facebook. I got an application ID and secret. Then I wrote the following script to access my app (just as told on the facebook page). <?php require './src/facebook.php'; $facebook = new Facebook(array( 'appId' => 'xxxx', 'secret' => 'xxxx', 'cookie' => true, // enable optional cookie support )); try { $me = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); } if ($facebook->getSession()) { echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>'; } else { echo '<a href="' . $facebook->getLoginUrl() . '">Login</a>'; } ?> Then I started running this script. It prompted me with the login link, then took me to the facebook login page. However, after I enter my facebook login details, I get this error page: Error. API Error Code: 100 API Error Description: Invalid parameter Error Message: next is not owned by the application. Could anyone help me a little bit please, I am really confused here about what's going on.

• Qt moc failure without an error message

  - by Robert Parker

  So I'm pretty new to Qt, and I've just inherited a project from someone else who is also new to Qt. He isn't around this week btw. We are using Visual Studio 2008, and have the latest version of Qt installed(4.6.2). The project builds on my coworker's machine fine, and I can get the project from svn and build it directly. But under any other circumstances it refuses to build on my machine, and it doesn't give me much of an explanation why. Even if I just do a 'build clean' and then a 'build' it doesn't work. Any slight modification will make it fail. When I try to build the entire project I get the error message: 1Moc'ing MatrixTypeInterface.h... 1moc: Cannot create .\GeneratedFiles\Debug\moc_MatrixTypeInterface.cpp;.\GeneratedFiles\Debug\moc_matrixtypeinterface.cpp 1Project : error PRJ0019: A tool returned an error code from "Moc'ing MatrixTypeInterface.h..." The moc tool doesn't give any sort of error message as to why it isn't working, and I wasted most of yesterday trying to figure out why. I got the command that VS was using to call moc, and I entered in the command line myself. It didn't write anything to the screen. Any ideas?

• Why do I get a NullReferenceException when using a style on a ContentPresenter?

  - by Robert Rossney

  I've created this template, which uses a style applied to the ContentPresenter so that I can bind the data object's Column property to Grid.Column, allowing the items to determine for themselves which column of the Grid they go into: <DataTemplate DataType="{x:Type local:MyObject}"> <ItemsControl ItemsSource="{Binding Items}"> <ItemsControl.Resources> <Style TargetType="{x:Type ContentPresenter}"> <Setter Property="Grid.Column" Value="{Binding Column}" /> </Style> </ItemsControl.Resources> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> </Grid> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DataTemplate> When I run the program, I get a NullReferenceException. The beginning of the hilariously long stack trace: at System.Windows.StyleHelper.ApplyAutoAliasRules(OptimizedTemplateContent optimizedTemplateContent, HybridDictionary childIndexFromChildID, FrameworkTemplate frameworkTemplate, FrugalStructList`1& childRecordFromChildIndex, FrugalStructList`1& triggerSourceRecordFromChildIndex, FrugalStructList`1& resourceDependents, HybridDictionary& dataTriggerRecordFromBinding, Boolean& hasInstanceValues) at System.Windows.StyleHelper.ProcessTemplateContent(FrameworkTemplate frameworkTemplate, FrugalStructList`1& childRecordFromChildIndex, FrugalStructList`1& triggerSourceRecordFromChildIndex, FrugalStructList`1& resourceDependents, ItemStructList`1& eventDependents, HybridDictionary& dataTriggerRecordFromBinding, HybridDictionary childIndexFromChildID, Boolean& hasInstanceValues) at System.Windows.StyleHelper.SealTemplate(FrameworkTemplate frameworkTemplate, Boolean& isSealed, FrameworkElementFactory templateRoot, TriggerCollection triggers, ResourceDictionary resources, HybridDictionary childIndexFromChildID, FrugalStructList`1& childRecordFromChildIndex, FrugalStructList`1& triggerSourceRecordFromChildIndex, FrugalStructList`1& containerDependents, FrugalStructList`1& resourceDependents, ItemStructList`1& eventDependents, HybridDictionary& triggerActions, HybridDictionary& dataTriggerRecordFromBinding, Boolean& hasInstanceValues, EventHandlersStore& eventHandlersStore) at System.Windows.FrameworkTemplate.Seal() at System.Windows.StyleHelper.UpdateTemplateCache(FrameworkElement fe, FrameworkTemplate oldTemplate, FrameworkTemplate newTemplate, DependencyProperty templateProperty) at System.Windows.Controls.ContentPresenter.OnTemplateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) at System.Windows.DependencyObject.OnPropertyChanged(DependencyPropertyChangedEventArgs e) at System.Windows.FrameworkElement.OnPropertyChanged(DependencyPropertyChangedEventArgs e) at System.Windows.DependencyObject.NotifyPropertyChange(DependencyPropertyChangedEventArgs args) ...etc. It's not the binding. I still get the error if I explicitly set the value in the style's setter to 0, say. And the error vanishes if I remove the style, though then all of the items end up in column 0. What's going on here? And how do I debug a problem like this?

• Why can't I Bind a viewmodel property to a dependency property of a custom control

  - by Robert

  I want to use a color picker in my wpf application and I saw a nice looking one on this codeproject page. The control works fine until I want to connect the control to a viewmodel. I created a small test program with this viewmodel: public class ColorViewModel : ViewModelBase { public ColorViewModel() { LineColor = Brushes.Yellow; } SolidColorBrush _brushColor; public SolidColorBrush LineColor { get { return _brushColor; } set { _brushColor = value; RaisePropertyChanged(() => LineColor); } } } The test program has a textbox and the colorpicker controls: <StackPanel Orientation="Horizontal"> <TextBlock Text="Please Select a Color" FontWeight="Bold" Margin="10" Foreground="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged}"/> <vw:ColorPickerControlView x:Name="ForeColorPicker" Margin="10" CurrentColor="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged }"/> </StackPanel> In the loaded event of the window I set the viewmodel to the datacontext like this: DataContext = new ColorViewModel(); The problem is that I can't seem to bind the LineColor property of the viewmodel to the CurrentColor property of the ColorPickerControlView. The CurrentControl property of the ColorPickerControlView seems to be fine. The constructor looks like this: public ColorPickerControlView() { this.DataContext = this; InitializeComponent(); CommandBindings.Add(new CommandBinding(SelectColorCommand, SelectColorCommandExecute)); } In the constructor of the UserControl there is the line this.DataContext = this; I read that is is necessary to bind the dependency properties. Do I override this line when I set my viewmodel to the datacontext and is that why I can't bind to the CurrentColor property? Is there any workaround? Or did I make another mistake?

• How to log communication of a WebService running on IIS 6.0?

  - by Martin Kirsche

  I'm running an ASP.NET WebService on IIS 6.0 that shows a lot of HTTP 500 (probably just exceptions from the WebService) inside the log at %systemroot%\System32\LogFiles\W3SVC1 on a customers site. Is it possible to log the content of those HTTP responses and there requests without modifying the WebService using IIS or a plug-in for IIS? I thought of using Wireshark or Fiddler to sniff on the HTTP traffic but I would prefer to just turn on an option inside IIS to make him log the communication (this should not be to hard since it is logging the requested URLs anyway)

• Are there old versions of Windows UX guidelines somewhere?

  - by Camilo Martin

  Since I've read Windows User Experience Interaction Guidelines (there's a PDF download avaliable) I've found it to be admirably self-deprecating, humbly pointing out their own horrible UI practices long scolded by Joel Spolsky. I'd like to know, however, what they had in mind while they made those mistakes. Is this (terrific) UX Guidelines document something new, or were there previous issues of such? If so, where can I find them? My prayers to Google yielded no leniency.

• Bind postback data from a strong type view of type List<T>

  - by Robert Koritnik

  I have a strong type view of type List<List<MyViewModelClass>> The outer list will always have two lists of List<MyViewModelClass>. For each of the two outer lists I want to display a group of checkboxes. Each set can have an arbitrary number of choices. My view model class looks similar to this: public class MyViewModelClass { public Area Area { get; set; } public bool IsGeneric { get; set; } public string Code { get; set; } public bool IsChecked { get; set; } } So the final view will look something like: Please select those that apply: First set of choices: x Option 1 x Option 2 x Option 3 etc. Second set of choices: x Second Option 1 x Second Option 2 x Second Option 3 x Second Option 4 etc. Checkboxes should display MyViewModelClass.Area.Name, and their value should be related to MyViewModelClass.Area.Id. Checked state is of course related to MyViewModel.IsChecked. Question I wonder how should I use Html.CheckBox() or Html.CheckBoxFor() helper to display my checkboxes? I have to get these values back to the server on a postback of course. I would like to have my controller action like one of these: public ActionResult ConsumeSelections(List<List<MyViewModelClass>> data) { // process data } public ActionResult ConsumeSelections(List<MyViewModelClass> first, List<MyViewModelClass> second) { // process data } If it makes things simpler, I could make a separate view model type like: public class Options { public List First { get; set; } public List Second { get; set; } } As well as changing my first version of controller action to: public ActionResult ConsumeSelections(Options data) { // process data }
