  • Why don't Direct2D and DirectWrite use traditional COM objects?

    - by David Brown
    I'm toying with a little 2D game engine in C# and decided to use Direct2D and DirectWrite for rendering. I know there's the Windows API Code Pack and SlimDX, but I'd really like to dig in and write an interface from scratch. I'm trying to do it without Managed C++, but Direct2D and DirectWrite don't appear to use traditional COM objects. They define interfaces that derive from IUnknown, but there appears to be no way to actually use them from C# with COM interop. There are IIDs in d2d1.h, but no CLSID. Of course, I'm really new to COM interop, so perhaps I'm just missing something. Can someone shed some light on this situation?

  • Data Driven MSTest: DataRow is always null

    - by David Back
    I am having a problem using Visual Studio data driven testing. I have tried to deconstruct this to the simplest example. I am using Visual Studio 2012. I create a new unit test project. I am referencing system data. My code looks like this: namespace UnitTestProject1 { [TestClass] public class UnitTest1 { [DeploymentItem(@"OrderService.csv")] [DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "OrderService.csv", "OrderService#csv", DataAccessMethod.Sequential)] [TestMethod] public void TestMethod1() { try { Debug.WriteLine(TestContext.DataRow["ID"]); } catch (Exception ex) { Assert.Fail(); } } public TestContext TestContext { get; set; } } } I have a very small csv file that I have set the Build Options to to 'Content' and 'Copy Always'. I have added a .testsettings file to the solution, and set enable deployment, and added the csv file. I have tried this with and without |DataDirectory|, and with/without a full path specified (the same path that I get with Environment.CurrentDirectory). I've tried variations of "../" and "../../" just in case. Right now the csv is at the project root level, same as the .cs test code file. I have tried variations with xml as well as csv. TestContext is not null, but DataRow always is. I have not gotten this to work despite a lot of fiddling with it. I'm not sure what I'm doing wrong. Does mstest create a log anywhere that would tell me if it is failing to find the csv file, or what specific error might be causing DataRow to fail to populate? I have tried the following csv files: ID 1 2 3 4 and ID, Whatever 1,0 2,1 3,2 4,3 So far, no dice.

  • NSFileManager - Copying Files at Startup

    - by David Schiefer
    Hi, I need to copy a few sample files from my app's resource folder and place them in my app's document folder. I came up with the attached code, it compiles fine but it doesn't work. All the directories I refer to do exist. I'm not quite sure what I am doing wrong, could someone point me in the right direction please? NSFileManager*manager = [NSFileManager defaultManager]; NSString*dirToCopyTo = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSString*path = [[NSBundle mainBundle] resourcePath]; NSString*dirToCopyFrom = [path stringByAppendingPathComponent:@"Samples"]; NSError*error; NSArray*files = [manager contentsOfDirectoryAtPath:dirToCopyTo error:nil]; for (NSString *file in files) { [manager copyItemAtPath:[dirToCopyFrom stringByAppendingPathComponent:file] toPath:dirToCopyTo error:&error]; if (error) { NSLog(@"%@",[error localizedDescription]); } }

  • Powershell: Select-Object with additional calculated difference value

    - by David.Chu.ca
    Let me explain my question. I have a daily report about one PC's free space as in text file (sp.txt) like: DateTime FreeSpace(MB) ----- ------------- 03/01/2010 100.43 DateTime FreeSpace(MB) ----- ------------- 03/02/2010 98.31 .... Then I need to use this file as input to generate a report with difference of free space between dates: DateTime FreeSpace(MB) Change ----- ------------- ------ 03/01/2010 100.43 03/02/2010 98.31 2.12 .... Here are some codes I have to get above result without the additional "Change" calculation: Get-Content "C:\report\sp.txt" ` | where {$_.trim().length -gt 0 -and -not ($_ -like "Date*") -and -not ($_ -like "---*")} ` | Select-Object @{Name='DateTime'; expression={[DateTime]::Parse($_.SubString(0, 10).Trim())}}, ` @{Name='FreeSpace(MB)'; expression={$_.SubString(12, 12).Trim()}}, ` | Sort-Object DateTime ` | Select-Object DateTime, 'FreeSpace(MB)' |ft -AutoSize # how to add additional column Change to this Select-Object? My understanding is that Select-Object will return a collection of objects. Here I create this collection from an input text file(parse each line into parts: datetime and freespace(MB)). In order to calculate the difference between dates, I guess that I need to add additional calculated value to the result of the last Select-Object, or pipe the result to another Select-Object with the calculation as additional property or column. In order to do it, I need to get the previous row's FreeSpace value. Not sure if it is possible and how?

  • CSS IE6 float right

    - by David
    How come when I have a div style at display: block; float: right, in IE6 the div still goes under the text, and not in the middle of it just floated to the right. It works in all other browsers, including IE7+. I need to have display block because if i do display inline, then the menu inside the div is all messed up. .content { display: block; } .float { width: 150px; display: block; float: right; } .nothing { display: inline; } the float class is not to the right of nothing class, its under it in IE6, know a fix?

  • Microsoft Sync Framework with Mutliple Client and Server Database

    - by David Osborn
    I'm working on changes to an application to have a local data store instead of connecting directly to the database server. The client app will then sync changes both ways between the server database and its local data store. I'm trying to implement the syncing solution using Microsoft Sync Framework. To be clear there is no server application, only the database server, but there are multiple clients. I have started implementing two classes that implement FullEnumerationSimpleSyncProvider, one called LocalSyncProvider and one called ServerSyncProvider. The LocalSyncProvider knows how to enumerate, insert, update, delete items from the local data store, and the ServerSyncProvider knows how to enumerate, insert, update, delete items from the database server. They each use the provided SqlMetadataStore and store the two metadata stores (one for the local and one for the server) on the local drive of the client. This means that each client will have its own metadata store for its local data store and its own metadata store for the server database. Is this actually going to work, does there need to exists only one server metadata store, or do I need to be using the Sync Framework differently?

  • Fluent NHibernate OptimisticLock.None() causes "The string 'none' is not a valid Boolean value."

    - by David Thomas Garcia
    I'm using the following mapping: public class LoadMap : IAutoMappingOverride<Load> { public void Override(AutoMapping<Load> mapping) { mapping.HasMany(x => x.Bids).OptimisticLock.None(); mapping.Version(x => x.Version); } } But when I try to create the session I get the following exception: [FormatException: The string 'none' is not a valid Boolean value.] [XmlSchemaValidationException: The 'optimistic-lock' attribute is invalid - The value 'none' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:boolean' - The string 'none' is not a valid Boolean value.] I'm using NHibernate 2.1.2.4000 and I was using Fluent NHibernate 1.0RTM, but tried the latest build 636 just to be sure this isn't something that was fixed recently or something. As a side note, in case I'm doing this all wrong, I would like to be able to make changes to the .Bids list without incrementing Version. I saw an example on Ayende's blog that did what I wanted with properties.

  • ASP.NET MVC 1.0: OutputCache, RenderPartial and WriteSubstitution

    - by David
    Hi folks, after digging into this topic and having the requirement, that a single page should be totally cached, except for a Html.RenderPartial("LogOnUserControl"); i couldn't find any working solution on this... the only "it getting warmer" thing i foudn was this solution , which unfortunately is not working with a "partial view", which requires the Request.IsAuthenticated attribute ( the fakeContext is losing this info ) Have you heard of any other solution to do this?!

  • Blacklight Expander problem while expanding programmatically

    - by David Brunelle
    Hi, I am doing a silverlight project in Silverlight 4 and I included the BlackLight project in my project so that I could use their new controls, especialy the dockpanel and the autoexpander, which is causing me at the moment some little problems. What I would like to do is to have several auto-expander that will expand or collapsed when I click on button. In my case more specifically, each auto-expander have a set of parameter to fill, which in turn will fill the other expander and the current one would collaps and the just filled one would expand. The idea is simple, yet when I use a button which is on one of my expander, it only works once... It would expand/collapse the first time, then after that, nothing. I trace the code and it seems to go through just fine, but the property value won't change Here is my code Private Sub BtnExpand_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles BtnExpand.Click ClientExpander.IsExpanded = False ProjetExpander.IsExpanded = True End Sub Could it be a known bug, or must I reset some flags to make it work? Thanks.

  • Error in WCF service - Silverlight client communication.

    - by David
    I created a WCF service and I planned to consume this in a Silverlight application. So I created the WCF service in the Website host project. The service is a simple WCF service that only returns a number - something like a Hello World WCF-SL. So after adding a service reference in the silverlight client project to the Service URI, after calling async the service method (by using the generated proxy), I get the following exception in the callback method: An error occurred while trying to make a request to URI 'http://localhost:4566/SLService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. I only created a HelloWorld WCF service with nothing else but a simple method that returns a dumb number and it's hosted on my locally. Must I have clientaccesspolicy.xml or crossdomain.xml? I acces my service locally. Every time I create a new simple/dumb WCF-SL solution, I get this error. I use VS2010 and Silverlight 4. I cannot get a simple/dumb WCF-SL solution working locally. Is there something wrong with the configuration? On another machine in the same network, it does work properly, so I assume something is misconfigured. Any thoughts?

  • SQL Server 2008 ContainsTable, CTE, and Paging

    - by David Murdoch
    I'd like to perform efficient paging using containstable. The following query selects the top 10 ranked results from my database using containstable when searching for a name (first or last) that begins with "Joh". DECLARE @Limit int; SET @Limit = 10; SELECT TOP @Limit c.ChildID, c.PersonID, c.DOB, c.Gender FROM [Person].[vFullName] AS v INNER JOIN CONTAINSTABLE( [Person].[vFullName], (FullName), IS ABOUT ( "Joh*" WEIGHT (.4), "Joh" WEIGHT (.6)) ) AS k3 ON v.PersonID = k3.[KEY] JOIN [Child].[Details] c ON c.PersonID = v.PersonID JOIN [Person].[Details] p ON p.PersonID = c.PersonID ORDER BY k3.RANK DESC, FullName ASC, p.Active DESC, c.ChildID ASC I'd like to combine it with the following CTE which returns the 10th-20th results ordered by ChildID (the primary key): DECLARE @Start int; DECLARE @Limit int; SET @Start = 10; SET @Limit = 10; WITH ChildEntities AS ( SELECT ROW_NUMBER() OVER (ORDER BY ChildID) AS Row, ChildID FROM Child.Details ) SELECT c.ChildID, c.PersonID, c.DOB, c.Gender FROM ChildEntities cte INNER JOIN Child.Details c ON cte.ChildID = c.ChildID WHERE cte.Row BETWEEN @Start+1 AND @Start+@Limit ORDER BY cte.Row ASC

  • Databinding a ListBox with SelectionMode = Multiple

    - by David Veeneman
    I have a WPF ListBox that I would like to Enable multiple selection in the ListBox, and Databind the ListBox to my view model. These two requirements appear to be incompatible. My view model has an ObservableCollection<T> property to bind to this ListBox; I set up a binding in XAML from the property to the ListBox.SelectedItems property. When I compiled, I got an error saying that the SelectedItems property was read only and could not be set from XAML. Am I binding to the wrong control property? Is there a way to bind a multiple-selection ListBox in XAML to a view model collection property? Thanks for your help.

  • MobileMe Connection - Cocoa

    - by David Schiefer
    Hi, I need to send a file to MobileMe via Cocoa. I stumbled across a .Mac framework from Apple but it hasn't been updated in years, so I don't want to use it due to possible compatibility problems it may cause. I think that the MobileMe.framework is private, so I don't think I can use it. What kind of alternatives are there available for me so that I can upload the file to MobileMe? I've also been looking into WebDav frameworks (since MobileMe is WebDav based), but I didn't find anything useful either. Thanks!

  • DNN 5.2.3 Stored Procedures executing numerous times during page loads

    - by David Neale
    After tracing the DB activity from a DNN 5.2.3 site I noticed that there are numerous identical calls to the database whilst loading the home page for the first time (afterwards the caching works successfully). //Procedure : Number of executions exec dbo.aspnet_Membership_GetUserByName @ApplicationName=N'DotNetNuke',@UserName=N'MYDOMAIN\ME',@UpdateLastActivity=0,@CurrentTimeUtc='2010-03-24 10:04:15:223' : 22 exec dbo.GetPortalAliasByPortalID @PortalID=0 : 15 exec dbo.GetUserProfile @UserID=8 : 11 exec dbo.GetUser @PortalID=0,@UserID=8 : 10 exec dbo.GetDatabaseVersion : 2 exec dbo.GetUserCountByPortal @PortalId=0: 2 exec dbo.GetDesktopModules : 2 exec dbo.KB_XMod_Forms_List @PortalId=0 : 2 exec dbo.KB_XMod_Templates_List @PortalId=0,@TemplateType=-1 : 2 Why so many duplicates?

  • Using Entity Framework with an SQL Compact Private Installation

    - by David Veeneman
    I am using Entity Framework 4 in a desktop application with SQL Compact. I want to use a private installation of SQL Compact with my application, so that my installer can install SQL Compact without giving the user a second installation to do. It also avoids versioning hassles down the road. My development machine has SQL Compact 3.5 SP1 installed as a public installation, so my app runs fine there, as one would expect. But it's not running on my test machine, which does not have SQL Compact installed. I get this error: The specified store provider cannot be found in the configuration, or is not valid. I know some people have had difficulty with SQL Compact private installations, but I have used them for a while, and I really like them. Unfortunately, my regular private installation approach isn't working. I have checked the version numbers on my SQL CE files, and they are all 3.8.8078.0, which is the SP2 RC version. Here are the files I have included in my private installation: sqlcecompact35.dll sqlceer35EN.dll sqlceme35.dll sqlceqp35.dll sqlcese35.dll System.Data.SqlServerCe.dll System.Data.SqlServerCe.Entity.dll I have added a reference to System.Data.SqlServerCe to my project, and I have verified that all of the files listed above are being copied to the application folder on the installation machine. Here is the code I use to configure an EntityConnectionStringBuilder when I open a SQL Compact file: var sqlCompactConnectionString = string.Format("Data Source={0}", filePath); // Set Builder properties builder.Metadata = string.Format("res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl", edmName); builder.Provider = "System.Data.SqlServerCe.3.5"; builder.ProviderConnectionString = sqlCompactConnectionString; var edmConnectionString = builder.ToString(); Am I missing a file? Am I missing a configuration stepp needed to tell Entity Framework where to find my SQL Compact DLLs? Any other suggestions why EF isn't finding my SQL Compact DLLs on the installation machine? Thanks for your help.

  • AS3 Embed Image Instead of drawing graphics

    - by David
    I've got a custom AS3 scrollbar that I need to modify. The scroll thumb (the draggable part of a scrollbar) is currently just done by drawing a rectangle. But I need it to look more like a real scrollbar. Not sure how to modify the below code to import/use a scroll thumb image: scrollThumb = new Sprite(); scrollThumb.graphics.lineStyle(); scrollThumb.graphics.beginFill(0x0066ff); scrollThumb.graphics.drawRect(0, 0, 1, 1); addChild(scrollThumb); I know that I would embed an image by doing something like this: [Embed(source="images/image1.png")] private static var Image1Class:Class; But then how do I set the scrollThumb = to the image? Thanks!

  • ASP.NET MVC POST Parameter into RouteData

    - by David Thomas Garcia
    I'm using jQuery to POST an Id to my route, for example: http://localhost:1234/Load/Delete with a POST Parameter Id = 1 I'm only using the default route in Global.asax.cs right now: routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); When I perform the POST, in my ActionFilter filterContext.RouteData.Values["Id"] is set to the default value of "". Ideally, I'd like it to use the POST Parameter value automatically if the URL comes up with "". I know it is posting properly because I can see the value of "1" in filterContext.HttpContext.Request.Params["Id"]. Is there a way to get RouteData to use a POST parameter as a fall back value?
