Bing Maps Silverlight Control final and ready to download

2009-11-11T00:39:00Z

I’m happy to report that the Bing Maps team shipped the final Bing Maps Silverlight Control with their Wave 14 update. Finally, no more screwing around with JavaScript but developing in in nice, good ol’ VB.NET or C# :-)

Btw, we updated Bing Maps as well which is especially sweet as the responsiveness got fantastic and we (finally) introduced Multi-point drag-drop directions :-)

Enjoy the goodness (which is usually VB but today Bing Maps) :-)

Free SQL Server 2008 Express How-To-Guide Series

2009-10-01T00:55:00Z

Thanks to the SQL Server Team we just released a free SQL Server 2008 Express How-To-Guide Series on msdev.com. During the next weeks we’ll also integrating parts of the series into the Visual Basic Developer Center, C# Developer Center, the Beginner Developer Learning Center, etc.

One video of the series: How do I query data in a database?

Given the fact that we don’t have unlimited resources (yeah, I know… that was the biggest surprise for me as well when I started working at Microsoft. “Where are all the bags with money standing around in each corner? What? There are none? D’oh!”) we tried to cover a pretty comprehensive area starting with basics like “How do I create a database?” over “How do I query data in a database?” to more advanced features like “How do I import data from another source (Excel, Access, XML, MySQL, ...) into a SQL Server Database?”.

Please let me know how you like the selection we made and if there are other topics you’d like to see*.

Enjoy!

Daniel

P.S.: We’ll rearrange the videos soon to have a nice walkthrough including “Topics you should know before watching this video” and “Next videos you might want to watch”.

* I don’t want to raise wrong expectations in that I’m promising other videos to show up on request but depending on the topic/amount of people requesting content we might extend the series.

How do I edit tabular data/data in a DataGridView in a details form?

2009-09-18T10:11:00Z

Abstract
This sample shows how to edit data from a DataGridView in a details form which opens when one double clicks on the RowHeader of the DataGridView. Since both forms are bound to the same datasource one sees an instant update on both forms when the user decides to save the data and additional roundtrips to the database are avoided. It also provides a brief introduction to DataBinding in .NET.

How to manage your parent’s/friend’s computer (The destiny of every computer geek)?

2009-05-01T00:19:24Z

Ever since I remember I was in charge of my father’s computer (Well, to be honest, there was a time when I tried to install Skool Daze – a Commodore 64 game – on his brand new XT where he was ahead in the game but this quickly changed ;-) ).

Taking care of my father’s computer was an easy talk while we lived together in the same house but got significantly more challenging when I moved out, especially now that I’m in the US and my parents are in Germany. Since “remote controlling” my father on the phone wasn’t as easy as I hoped it to be (without going into details, I guess you know what I’m talking about…) I tried a couple of different programs including “Remote Assistance”, vnc, msn messenger and others over the time which all had different constraints. Without complaining to much none of them truly satisfied me. Fortunately though a friend introduced me to TeamViewer while we were struggling to setup his development environment and I’m using it ever since. Like Paint.NET, .NET Reflector, Fiddler, Process Explorer, FileZilla, … this is a “must have” tool for everybody doing IT-related work and getting regular requests from family and friends about “why the printer isn’t working anymore” or similar issues (I should probably write a “Must have tools” post).

To me it came down to a couple of things I liked about TeamViewer:

Didn’t have to worry worry about firewalls, IP addresses, NAT. It just worked
Free for private use
Can be run without being installed
Can be installed to run as a service on your parent’s computer which allows you to connect to this computer as long as it’s online

If you’re intrigued and have the same need (otherwise, what are you doing here ;-) ) give it a try and share your thoughts.

Happy administration!

When using LINQ to XML why don’t I get results if I don’t import a XML namespace?

2009-04-30T01:38:00Z

Hi,

I posted a bit of code the other day which I used to get a list of all Code Snippets we ship in Visual Studio. In a nutshell, I used XElement.Load to create a new XML document from a filename from which I then read elements from (There are way to many ”from” in this sentence ;-) ). Unfortunately, I forgot to import the XML Namespace in the code I posted which caused my code not to return any results (but instead provided me with a brilliant opportunity to write another post. hehe :-) ).

Let’s have a look at the code which is causing trouble and a Code Snippets to understand what’s going on (you can find the complete code including the Snippet class in the aforementioned post):

Dim query = _

From file In My.Computer.FileSystem.GetFiles( _

"C:\Program Files\Microsoft Visual Studio 10.0", _

FileIO.SearchOption.SearchAllSubDirectories) _

Where file.EndsWith(".snippet") _

Order By file

Dim snippets As New List(Of Snippet)

Dim snippetDocument As XElement

Dim snippet As Snippet

For Each item In query

snippetDocument = XElement.Load(item)

If snippetDocument...<Title>.Value IsNot Nothing Then

snippet = New Snippet With {.Title = snippetDocument...<Title>.Value.ToString _

, .Description = snippetDocument...<Description>.Value.ToString _

, .Path = item _

, .Size = New System.IO.FileInfo(item).Length}

snippets.Add(snippet)

End If

Code Snippet

<?xml version="1.0" encoding="utf-8"?>

<Title>Activate a Running Application by Name</Title>

<Author>Microsoft Corporation</Author>

<Description>Activates a running application using the name of the application.</Description>

<Shortcut>appActNa</Shortcut>

</Header>

<Namespace>Microsoft.VisualBasic</Namespace>

</Import>

</Imports>

<ID>applicationName</ID>

<Type>String</Type>

<ToolTip>Replace with the name of the application. This is often the title of the application window.</ToolTip>

<Default>"Untitled - Notepad"</Default>

</Literal>

</Declarations>

</Snippet>

</CodeSnippet>

</CodeSnippets>

As you can see there is a <Title> element in the the Code Snippet to which we are referring to in the code above… or are we?

Let’s dig a bit deeper, open the compiled program in .NET Reflector and disassemble it (if you don’t have .NET Reflector you have to stop reading NOW and get it!! Seriously, this tool is a life-safer and I’ve learned soooo much using it!).

If you focus on the parts I highlighted in red in the above picture you can see that <Title> consists out of the XML name and the XML namespace (check out XName..::.Get Method (String, String)). Since I didn’t import the namespace in my program an empty namespace got used resulting in the qualified name Title which doesn’t fit the namespace of the Code Snippet {http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet}Title, hence my program didn’t return any results.

To solve this problem I added the following line of code to my program

Imports <xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">

and – finally – all is good :-)

Hopefully this solved the mystery of the missing results ;-)

Best!

How to get a list of all files of a directory (subdirectories included)?

2009-04-23T22:06:00Z

I needed to create a list of all Code Snippets we ship in Visual Studio the other day containing their title, description and path on disc and size. As you might know, Code Snippets are stored in multiple directories below "%ProgramFiles%\Microsoft Visual Studio 10.0" so I had to traverse all the subdirectories of the aforementioned path to find all snippets.

Fortunately – linq to the rescue – this came down to a few lines of code :-)

Dim query = From file In My.Computer.FileSystem.GetFiles("C:\Program Files\Microsoft Visual Studio 10.0", FileIO.SearchOption.SearchAllSubDirectories) _

Where file.EndsWith(".snippet") _

Order By file

This statement gives you a List of Strings (or, to be a bit more precise, a System.Linq.IOrderedEnumerable(Of String)) which you can walk over to do all kinds of crazy things.

Here is what I did to solve the problem I described above:

Imports <xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim query = From file In My.Computer.FileSystem.GetFiles(txtPath.Text, FileIO.SearchOption.SearchAllSubDirectories) _

Where file.EndsWith(".snippet") _

Order By file

Dim snippets As New List(Of Snippet)

Dim snippetDocument As XElement

Dim snippet As Snippet

For Each item In query

snippetDocument = XElement.Load(item)

If snippetDocument...<Title>.Value IsNot Nothing Then

snippet = New Snippet With {.Title = snippetDocument...<Title>.Value.ToString _

, .Description = snippetDocument...<Description>.Value.ToString _

, .Path = item _

, .Size = New System.IO.FileInfo(item).Length}

snippets.Add(snippet)

End If

DataGridViewSnippets.AutoGenerateColumns = True

DataGridViewSnippets.DataSource = snippets

End Sub

End Class

Public Class Snippet

Private _Title As String

Private _Description As String

Private _Path As String

Private _Size As Long

Public Property Title() As String

Get

Return _Title

End Get

Set(ByVal value As String)

_Title = value

End Set

End Property

Public Property Description() As String

Get

Return _Description

End Get

Set(ByVal value As String)

_Description = value

End Set

End Property

Public Property Path() As String

Get

Return _Path

End Get

Set(ByVal value As String)

_Path = value

End Set

End Property

Public Property Size() As Long

Get

Return _Size

End Get

Set(ByVal value As Long)

_Size = value

End Set

End Property

End Class

Btw, if you bind the result to a DataGridView you can copy&paste from there into excel. Needo :-)

Cheers!
