• Visual Studio 2008 (Pre-release) XAML: setting BitmapImage.UriSource from binding doesn't work

  The following should display a picture for a list box item: <Window.Resources> <DataTemplate x:Key="ImageTemplate"> <Image> <Image.Source> <BitmapImage UriSource="{Binding}" /> </Image.Source> </Image> </DataTemplate> </Window.Resources> <Grid> <ListBox> <ListBoxItem ContentTemplate="{StaticResource ImageTemplate}"> C:\picture.jpg </ListBoxItem> </ListBox> </Grid> ... but I get an exception: "Property 'UriSource' or property 'StreamSource' must be set."

• Game Technologies: DirectX, XNA, XACT, etc. Correct version of the XACT

  While trying to build the project with simple sound as described in XNA Help the error XACT could not load the data provided. Make sure you are using the correct version of the XACT tool appeared. I have October SDK installed and no attempt to build sound files with August SDK taken. Have seen some posts with similar problem here but no real solution. Is there any kind of restriction meaning the size or other sound properties I used standard Windows file "chord.wav" for my experiment. From what I understand the XNA Framework only works with the August version of the DX SDK... http://letskilldave.com/archive/2006/10/06/October-DirectX-SDK-releases-today.aspx http://www.thezb ...Show All

• SQL Server How do I add an ODBC connection data source as a Data Flow Source

  I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds. Have I missed something in my set up of the OLE DB source / connection Will a DSN source be faster Thanks in advance ADG How do you know that the slowness is in the OLE DB sauce component and not in the destination component How are you setting up the OLE Source component Providing a query would be faster than selecting a table from the dropdown list. ...Show All

• Visual Studio Express Editions Getting an Image from a WebDocument

  I've been experimenting with web page manipulation and I've come across a small problem. I want to be able to copy the contents on an Image that is on the web page into my own picturebox control. I can locate the image, using the documents Images collection, but the collection only contains HTMLElements, not the actual image contained in the element. Has anyone managed to grab the individual image from the document Any ideas you have would be appreciated, thanks. Yes, I know I can get the url, etc. What if I am working offline Since the picture is displayed then you should be able to reference the image somehow. The picturebox control will load an online image asynchronously, but that isnt what I'm looking for. ...Show All

• Windows Forms Setting default values in bound controls on a form

  How do you set default values for bound fields in windows forms There are times when specifying the default value in the underlying dataset is insufficient. The fields are bound to a binding source which has an AddingNew event where you can do something like: e.NewObject = <something>. The something however needs something of the same type or else you get an error message of "Objects added to a BindingSource's list must all be of the same type". I assume this is a DataRowView except I don't don't know how to create one in this context. One way is to use code like this: DataRowView rowView = dsNorthwind.Customer.DefaultView[0] but this implies the row is already in the underlying dataset except it isn't becaus ...Show All
