If you receive a portable drive and want to see the list of folders, you can output it to a text file.
To save the list of folders in a text file execute the following command in the command window:
dir P: /AD /B >> "C:\folderlist.txt"
where P: is the drive letter of the portable drive
The file will be created in the root directory of the C: drive.
My friend just bought a new Lenovo ideapad z580 laptop with Windows 8 on it. She was not sure if her special statistical programs will run on Windows 8, so she asked me to remove Windows 8 and install her copy of Windows 7 64 bit on it. As it turned out the Lenovo laptop arrived with UEFI boot turned on and it did not accept the original Windows 7 64 bit DVD as a boot device. The solution is to turn off UEFI in the BIOS and enable the legacy boot.
To enter the BIOS
Turn off the UEFI boot mode in the BIOS
Save the BIOS settings
The computer will automatically restart into Windows 8
Boot from the Windows 7 DVD
Install Windows 7

If you need to make breaking changes in your source code that will be deployed later to production, but first have to be tested in the development environment you can include conditional compilation symbols to specify which lines will be included in the application for certain environments. This way you can maintain environment specific versions of the source code, the current version for production and the new version for development and testing.
In this example we will make a change in our source code that we want to deploy to the Development environment for testing, but not to QA, UAT and Production.
#if new_version
// New code
int a = 1;
#else
// Old code
int a = 0;
#endif
int b = a;
If the Dev configuration is selected the new code will be compiled into the application
If another configuration (QA) is selected the old code will be compiled into the application

I work on multiple computers using different operating systems.
When I tried to open a web service solution in Microsoft Visual Studio 2010 on my Windows 7 64 bit workstation I got the following error message:
“The project file … has been moved, renamed or is not on your computer.”
I could verify that the file was on my computer at the stated location, and I could open the same solution in Microsoft Visual Studio 2010 on a Windows Server 2003 32 bit machine. I have recreated the setup file on my Windows 7 64 bit machine, and everything looked all right, but when I closed the solution and tried to open it again I got the same error message. I have counted the length of the full path of the setup project and I got 153. As it turned out, the path was not too long.
The following steps solved the problem, but I still don’t know why:
There are two ways to modify a WordPress theme: the fast way and the smart way.
The fastest way is to edit the files of the theme by selecting the files with the “Appearance”, “Editor” menu option. The drawback is that when the theme is updated your customizations will be wiped out. The update process will overwrite the files you changed, so all of your changes will disappear.
A better way of modifying a theme is to create a “child theme”. This has two advantages:
In this tutorial we will create a child theme for the Simplify theme
Right click the empty area of the directory listing and select “Create new file”
Enter style.css as the file name and click OK
Copy the following to the editor window.
/* Theme Name: Simplify Child Theme URI: http://example.com/ Description: Child theme for the Simplify theme Author: Your name here Author URI: http://example.com/about/ Template: simplify Version: 0.1.0 */
@import url("../simplify/style.css");
Select and activate the new child theme

During the Visual Studio 2010 Web Application and Web Service deployment the prior setting of the application pool name is lost. The installer does not assign the correct application pool to the virtual directory, it will be assigned to the Default Application Pool.
If different .NET versions are assigned to the same application pool, the older .NET applications stop working.
To handle this problem in the VS 2010 msi file follow the steps below.
' Sets the Application Pool of the Virtual Directory
' Usage:
' Right click on the Web Setup project
' Select Add, File
' Select C:\TFS\HALTeam\Other\Deployment_Tools\SetAppPool.vbs
' Right click on the Web Setup project
' Select View, Custom Actions
' Right click on Commit and select "Add Custom Action"
' Select the SetAppPool.vbs file in the Web Application Folder
' In the Properties window of SetAppPool.vbs enter the CustomActionData:
' Example: /vdir:HALGraphicUpload /appPool:HALGraphicUpload
Option Explicit
Dim customActionData, customActionArray, vdirName, appPool, vdirObj
' Read the CustomActionData of the Installer
customActionData = Session.Property("CustomActionData")
' Parse the data from the CustomActionData
customActionArray = Split(customActionData) ' Splits by the space
vdirName = Replace(customActionArray(0), "/vdir:", "")
appPool = Replace(customActionArray(1), "/appPool:", "")
' Set the Application Pool property of the Virtual Directory
set vdirObj=GetObject("IIS://localhost/W3svc/1/Root/" & vdirName)
vdirObj.Put "AppPoolId", appPool
vdirObj.SetInfo
When you debug your Visual Studio web application you want to start and stop Internet Explorer automatically when you start and stop the debugging session. With the default settings Internet Explorer starts automatically when you start debugging, but it does not close when you stop the execution.
To enable the automatic stop, enable debugging in Internet Explorer:
Next time when you debug in Microsoft Visual Studio Internet Explorer will start and stop with the debugging session. When you close Internet Explorer it will stop the debugging session in Visual Studio.
