Connecting Bluetooth Keyboard to Windows 8 Samsung Developer Preview Computer Requires Passcode

September 19, 2011 / 1 Comment
AUTHOR: Mark

The first time I connected my computer Bluetooth keyboard to the Windows Build Samsung Developer Preview tablet I was prompted with a passcode to type into the keyboard:

SNAGHTML9819628

Entering the passcode followed by ENTER successfully paired the keyboard.

Later on, the pairing quit working so I made attempts to reconnect.  Unable to successfully get the two devices to recognize each other again, I Removed the keyboard from the list of Bluetooth devices. 

Unfortunately, when attempting to add [...]

SQL Server 2008 SP2 Uninstall Fails

September 6, 2011 / No Comment
AUTHOR: Mark

Recently, I tried opening an MDF file from my SQL Server Express instance only to discover be prompted with the following error:

The database cannot be opened because it is version 661. This server supports version 662 and earlier. A downgrade path is not supported.

This error message is completely misleading, however, as it indicates that my installation of SQL Server is later than the database version that I am attempting to open.  In actual fact, the  issue is that SQL Server 2008 (SP2) supports 662 while while SQL Server 2008 R2 SP1 supports version 661.  A more accurate message [...]

January 23, 2009 / 1 Comment
AUTHOR: Mark

In this edition, I am going to wrap up a few loose ends with a selection of miscellaneous keyboard shortcuts and links to a summary keyboard shortcut poster.

Debugging:

I realize that none of you would write bugs, but in case you meet someone that does or perhaps on occasion you need to debug some code in order to explain a complex algorithm, here are some invaluable debugging keyboard shortcuts.

  • F9 and CTRL+F9
    F9 creates or removes a breakpoint based on the cursor’s current location. CTRL+F9 toggles whether a breakpoint is enabled or not.
  • F5, CTRL+F5 and SHIFT+F5
    CTRL+F5 launches the application or begins running the [...]

    Visual Studio Keyboard Shortcuts for Editing (MSDN Flash -Jan. 19, 2009)

    January 3, 2009 / 2 Comments
    AUTHOR: Mark

    Knowing all the keyboard shortcuts for editing shows off our programming prowess, just like it would it did for programmers that could use VI.   Rather than describing the well known ones like CTRL+F and CTRL+H, I am going to review some that are more unique to Visual Studio Programming:

    Find

  • CTRL+I/CTRL+Shift+I
    imageIncremental Search: Turns on incremental search so that characters typed next will be search for in sequence within the file.  Use CTRL+Shift+I to search up and ESC to cancel.
  • CTRL+Shift+F and Ctrl+Shift+H
  • Find in Files:  Displays the find dialog with Look in: set to [...]

    Unattended Installation of Team Foundation Server 2008 on Windows 2008 with SQL Server 2008

    December 15, 2008 / 1 Comment
    AUTHOR: Mark

    The following are my instructions for installing a new Team Foundation Server 2008 with SP1 onto Windows 2008 with SQL Server 2008. Throughout, I followed the
    TFS install guide and tried to automate where it didn’t distract me too much from the task at hand. I followed the Single-Server Team Foundation Server Installation.Folder LayoutFor the scripts to work successfully, you need the following placed into a local directory (probably without spaces in the name):

    .\
    dotnetfx35.exe.\SQLServer2008\ (SQL Server 2008 install).\TFS2008\ (TFS 2008 install) .\

    MSDN Flash: Keyboard Visual Studio Tips & Tricks for Dec 15. 2008

    December 5, 2008 / No Comment
    AUTHOR: Mark

    Originally, I was going to focus on shortcuts for the various build/compilation options within Visual Studio 2008.  However, things become a little more complicated in terms of which keyboard shortcut to use because it depends on your keyboard mapping scheme.  In this edition, therefore, I am going to discuss the Keyboard Options dialog – where different keyboard schemes are available for selection.

    During the first launch of Visual Studio 2008, you are prompted with which keyboard scheme to use.  The typical options are (Default), Visual C# 2005, and Visual Basic 6. Fortunately, you can change your selection via the Tools->Customize… menu [...]

    MSDN Flash: Keyboard Visual Studio Tips & Tricks for Nov 17. 2007

    November 18, 2008 / No Comment
    AUTHOR: Mark

    Frequently, while browsing code, we want to drill down into a method to see the implementation and then jump back out again to continue browsing code at the caller. One invaluable keystroke for doing this is F12. Placing your cursor on any identifier, you can use F12 to drill into its declaration. This works both for types as well as their members. In fact, you can use the same keystroke to jump to the definition of types in the .NET Framework. This is a great way to browse through the type’s members to see header information, including the documentation of [...]

    Dynamically Typed Objects with C# 4.0

    November 4, 2008 / 8 Comments
    AUTHOR: Mark

    One of the announcements that emerged from the PDC is C# 4.0′s support for dynamically typed objects.  These are objects whose type is not determined until runtime.  Variables that point to such types are declared with a new contextual keyword, dynamic.  Support was added so that API calls into dynamically type languages (such as scripting languages) could be supported.  Another example where dynamically typed object support is useful is calling into IDispatch objects (something supported by VB but not C# until now).

    In order to investigate how dynamic objects worked I decided to create a working sample that dynamically went against [...]
