• Silverlight (formerly WPF/E) Event Bubbling Problem

  I can't determine if the SDK is wrong or the implementation. Here is the issue: The SDK states: " WPF/E supports the concept of a bubbled event for input events such as mouse events. A bubbled event is an event that is passed from a child object and is forwarded upwards to each of its ancestors in the object hierarchy. " But when I use the following XAML: <Canvas xmlns=" http://schemas.microsoft.com/client/2007 " xmlns:x=" http://schemas.microsoft.com/winfx/2006/xaml " Loaded=root_Loaded" MouseLeftButtonUp=buttonUp" x:Name="mainCanvas"> <Canvas x:Name="button" MouseLeftButtonUp=buttonUp"> <Rectangle x:Name="topRect" ...Show All

• Visual Studio Team System Get file attributes - checked out or not (in code)

  Hi, I am wondering if there is any command in the TFS API that lists all files in a folder, and shows whether they are checked out or not. I do know of the QueryPendingSets command, but I would have to combine that with a list of ALL files to get their state - checked in/out. I saw this helpful post about listing checked out files: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=153326&SiteID=1 Is there any API call that allows me to see this in one call P.S. For some reason, the 'Insert Hyperlink' button does not seem to work in FireFox. Hi Eugene, Thanks for the suggestions - I have already looked at the methods you suggested. The GetItems methods does not seem to have an overload that allows me to filter by the state o ...Show All

• Visual Studio Express Editions How do I set the fontsize and color of body text using mailto:?

  -Visual Basic 2005 Express- I've searched the internet and forums for 2 hours looking for a way to 'programmatically' change an emails font and color in the body.

• Visual Studio 2008 (Pre-release) ICollectionView grouping

  I have virtual IList<T> implementation (Db4oList) for db4o ( www.db4o.com ) object database and want to add ICollectionView implementation. I have described one problem with ObservableCollection here: http://forums.microsoft.com/MSDN/showpost.aspx postid=571091&siteid=1 But there is also related problem: Db4oList keeps only specified amount of objects in memory. E.g. say I have 1 000 000 objects (items) in it loaded from db4o database. I keep only 1 000 of them in memory when enumerating the list or using its indexer to access items. I have no problem with sorting or filtering, but the problem is with grouping, because when ICollection.Groups could have too many objects and because it is defined as ReadOnlyObser ...Show All

• .NET Development How to send folder in stream

  Is where any way to send folder direct in stream with all content inside it (structure, files, subdirs) with an ability to recover it later from that stream You can serialize FileInfo objects into a stream. You'll find a code sample below. When you deserialize the stream, you could re-create the folders with the information in the FileInfo object. What you're going to do with a file is murky; you can recreate it but not recover the data. using System; using System.Windows.Forms; using System.IO; using System.Runtime.Serialization.Formatters.Binary; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sende ...Show All

• Visual Studio Express Editions using VBE across a LAN

  Hello! What I have done so far I have just taught myself some VBA where I produced a module inside Excell on my own P.c that displays some statistics from an SQL database held separately on on a server on the LAN (Using a connection string to the SQL Database ) T he Excell file is in use also by other people in my company who have it locally and produce the statistics and reports thanks to the connection string that I refer to above to the remote SQL database. (It works quite well but managing data and displaying the results in a worksheet are quite like knitting jelly) What I want to do next I want to move on and learn VBE and I am wondering about something which is ; I know that I can probably u ...Show All

• .NET Development What did I do wrong (Getschema method in SQLServerCE)?

  I have a problem with the Getschema method in the SQLServerCe namespace - I am fairly new in C# so I may have overlooked something. My problem is that I have only the C# Express edition (I don't have the mobile projects) so I am "forced" to make my own viewer for my SQL Compact databases (.sdf) as I can't use SQL server Management Studio Express for these files. However, when I use the Getschema() method in the corresponding namespace it seems to not work. This is the code I used: string connstring = @"Data Source=c:\!studiec#\betatest.sdf" ; SqlCeConnection myconn = new SqlCeConnection (@connstring); myconn.Open(); DataTable mytable = myconn.GetSchema(); I get the error "Spe ...Show All

• SQL Server Is it recommendable?

  Dear folks, we've got old tables with triggers which reading data from systables and some stuff... I know that it's stupid way to gather info but.. So that, now, using Sql25k is recommendable to use INFORMATION_SCHEMA tables or betther, take data from sys views Thanks in advance and regards, Hi, For my information system tables in SQL 2005 are hidden and they are not accessible, even they cannot be queried, actually it's not a matter of rights, even you're a DBA with full rights you will not be able to utilize the system tables, so it's strongly recommended to use the INFORMATION_SCHEMA views ( over 230 views ) they offer a great deal of metadata, also it will be more efficent as they provided by MS itself, for SQL 2k I ...Show All

• .NET Development Double Trouble - bug in double?

  There appears to be a bug with Double, unless I'm missing something The following lines of code are basically all the same. However, some of the numbers evaluate to "true" while others evaluate to "false". I can not figure this out. Response.Write((Convert.ToDouble("3.170404") == 3.170404)); // is true Response.Write((Convert.ToDouble("5.170404") == 5.170404)); // why is this false Response.Write((Convert.ToDouble("6.170404") == 6.170404)); // why is this false Response.Write((Convert.ToDouble("8.170404") == 8.170404)); // is true Any ideas This occurs in both .NET 1.x and 2.x.
