Opening Microsoft Office OneNote files without OneNote being installed can be a bit of a pain but it is possible and therer are numerous options to do so. Below I will provide a couple different ways to go about reading the OneNote notebook or file. The first of which is if someone has sent you a .one (OneNote) file and you want to open it without having to ask them to provide a different format. The second method will be providing them numerous different formats that they could provide you the OneNote file in including Microsoft Word (.doc and .docx) and HTML.

The first method I will explain is opening the file without having to ask the person who sent you the file to do anything. Regardless of what method you want to use to view the files you will be required to download and install the trial of Microsoft Office OneNote that lasts for 60 days. After 60 days you should still be able to view files but you will not be able to edit them.

To get the path where SQL Server 2005 stores data files for databases, you can use the following T-SQL script:


USE master
GO

DECLARE @data_path nvarchar(256)
SET @data_path = (SELECT SUBSTRING(physical_name, 1, CHARINDEX(N'master.mdf', LOWER(physical_name)) - 1)
FROM master.sys.master_files
WHERE database_id = 1 AND file_id = 1)

SELECT @data_path AS DataPath

It uses the built-in “master” database, finds the physical path to it from the “master.sys.master_files” view, then takes a substring to get just the path portion.

I use SimpleViewer to display some of the image galleries on my personal WordPress blog and decided I wanted to change the caption location. Moving the caption to below the image itself instead of below the thumbnails is easy however you must have the source code that comes with purchasing the product. I figure it is worth the money if this is a gallery you are using as it would cost much more in time to develop the gallery yourself.

The default location of the caption is shown below in the image.

Wireshark, previously Ethereal, is a network protocol analyzer that allows you to inspect the packets of hundreds of different protocols. The upgrade process is very straight forward but it doesn’t hurt to mention that it is OK to go ahead and uninstall the previous version during the upgrade. Basically you will be uninstalling your current version of Wireshark (1.0.2 in my case) and then installing the new version (1.0.7). Follow the directions below to complete the Wireshark upgrade process.

  1. Download Newest Version: You can download the latest version of Wireshark here.
  2. Read the rest of this entry »
