• Visual Studio 2008 (Pre-release) DrawImage "InterpolationMode" in WPF?

  I need to control the interpolation of a BitmapSource when it is rendered to the screen - I have an application requirement that says the images must be interpolated using nearest-neighbor when resized. I have fruitlessly looked for something in WPF corresponding to System.Drawing.Drawing2D.InterpolationMode. The closest I have gotten is RenderOptions.SetBitmapScalingMode(...,...) but it does not do nearest-neighbor interpolation. Any ideas Seems strange that the interpolation-options would not be available in WPF. Thanks, Andreas Hallberg There's no way to natively select nearest neighbor from within WPF. The default image rescaling algorithm is the "fant" scaler which uses a tr ...Show All

• .NET Development Problem Importing Data From Excel

  I'm attempting to import data from a spreadsheet and I have the following problem. Some of the fields appear blank even though in the spreadsheet they have values further down the sheet. This is my connection string. conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:\Documents and Settings\mark.bosman\Desktop\test.xls;" & _ "Extended Properties=""Excel 8.0;HDR=YES;MaxScanRows=0;""" The rest of the data populates fine, but two columns containing integer values that are not populated till around the 150th row don't appear.

• .NET Development Setting An Object To Null Ensures Getting It Garbage Collected?

  Will setting an object to null ensures getting it marked for garbage collection even if it still within its execution scope The reason I'm asking this is to know whether or not setting a global object (defined in the class scope) to null ensures getting it garbage collected by the runtime GC (even if it's still not out of scope). Hi MandarDate Setting references to null is not necessary in .NET. The GC will determine when an object is no longer reachable and collect it.

• Visual C# Instance Method V Class Method...

  Hello all, When we have: String abc = etc etc; We can call abc.IndexOf(<some string>) Whereas when we have an Array we need to use the class method... string[] bcd = etc etc; The equivalent is: Array.IndexOf(bcd, <object>); They both effectively do the same thing (on their respective objects), i'm just curious as to why the difference in syntax in calling them Thank you Chris Arrays are ordered collections of items of the same data type that are accessed using the array name in conjunction with the offset from the start of the array of the desired item. Whereas a string is a reference type that represents a group (string) of unicode characters. From there it is all in the syntax. Me ...Show All

• SQL Server .dtsx package from Informix using ODBC

  Help! I'm trying to create a simple .dtsx package that imports data to SQL server 2005 from an informix 7.3 db using an ADO.net ODBC connection. I am first creating the groundwork for the dtsx package in SQL server using the wizard, and then editing the file later in visual studio. My data source SQL in the dataflow task is simple and it works great until I hit a locked record on the Informix database. select <coulmns> from <table> Where <condition> The work around syntax for the locked row on the informix DB should be: set isolation to dirty read go select <coulmns> from <table> where <condition> This syntax will return the data correctly using a non-microsoft ...Show All

• SQL Server Setting report credentials programmatically -- this should be easy!

  This should be easy... but I can't figure out the answer from MSDN help or from google. I have my reports set up with a custom data extension. You can access the reports via report manager and enter credentials and view the report. But, the reports will be accessible via a web application as well. In this case, the user will already be logged in, so I want to either disable credentials on the fly, or set the username/password to empty. Then I set a hidden session ID parameter and the data extension can authenticate using this parameter. I know about viewer.ServerReport.ReportServerCredentials but for the web, there seems to be no ReportServerCredentials class. I have seen the help topic at http://msdn2.microsoft.com/en-us/library/microsof ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Xbox 360 Guides in XNA

  Hi there, I've been playing around with the framework and I have a little question for any MSFTies who can answer. On the Windows side of things, if we want to call up any useful built in functions of Windows like say the common dialog box colour picker (for say, a player's car paint job) or a MessageBox (you've reached the end of the demo!), we can still do so by calling in to the Windows.Forms namespace. On the Xbox 360 side though, any such UI we would have to recoded manually. However, as we all know, there are certain built in elements of UI on the 360 too in the form of the various Xbox Guide slide out panels. Currently, access to one of these does exist in XNA (The save Location guide for letting the user choose a Memor ...Show All

• SQL Server Monitor Jobs on SQL Server

  Hi, I'd like to know if I can monitor all the jobs in SQL Server 2000 or 2005 using SMO Objects. Specifically, I'd like to know if the jobs has been run, executed suceefully or not (recording to Log files). I also like to view/enumerate all the existing jobs. I'd like to know if all these are possible if I use SMO Object with Visual Basic.net.. If possible please give me sample code or web site so I can learn how to do it. Thanks for reading my post.

• Game Technologies: DirectX, XNA, XACT, etc. Question about location and number of main game objects

  Ok so I'm still starting out with XNA, so apologies if this sounds like a strange question. I'm still getting the hang of the architeture of XNA, and am having trouble working out the numbers and location in the heirarcy of certain important game objects. Im using a GameState style engine for my game, and refer to each "state" as a "screen" This is my current layout... GraphicsDevice - One in main game class, passed through constructors to relevent functions ContentManager - One per "screen", made sense as if a screen unloads then all its content should unload too ( ) SpriteBatch - Currently one for each low level game object (eg, Sprite object, UIElement object) however i think this should be higher up and pa ...Show All

• Visual Studio Express Editions Visual Basic 2005 Express Edition Data Binding is not updating the database

  Hi Microsoft Community, I'm a new visual basic developer and am using the visual basic 2005 express edition with sql server 2005 express edition.  I've been going through some lessons and have encountered a situation that I'm hoping someone can identify what the issue is.
