Corporations maintain multiple server environments for development, testing and production purposes.
All of these environments require specific settings to connect to the databases and other resources. When the build master builds the application for the specific environment the build process has to select the appropriate configuration and build it into the installer file for deployment.
It is a good practice to store these environment specific config files in a folder that also designates the Visual Studio version.
Console applications and Windows services
For console applications and Windows services place this folder into the “Source” folder.
In Microsoft Visual Studio you can add a folder to a project, but it will be created in the directory where the project file is located. To add a folder to a project when the folder is not in the project directory we have to manually edit the project file. In this example we will add a folder to our main project that contains the environment specific config files. The “Config_2012” folder is located in the “Source” folder outside of the “Project_2012” project directory.
The following steps will add the “Config_2012” folder to the project
- Create the “Config_2012” folder in Windows Explorer
- Add the environment specific config files to it
- Add the folder to source control
- Open the solution in Visual Studio
- Right click the main project and select Unload Project
- Right click the main project again and select Edit…
- Add the following to the project file
- Save the project file
- Right click the main project file and select Reload Project
The “Config_2012” folder will appear in the Solution Explorer and the config files will be added as linked files.
Web applications and web services
For web applications and web services place the Config folder into the web application folder
To add the config folder and files to the web application
- Open the web solution in Visual Studio
- Select the web project
- Click the Show All Files button on the Solution Explorer toolbar
- The Solution Explorer will display all files in the web application folder
- Right click the Config_2012 folder and select Include In Project
- Select all the config files in the Config_2012 folder
- Right click the selection and select Properties
- Set the Build Action to None
- Click the Show All Files button on the Solution Explorer toolbar again to hide the excluded files
The Microsoft SQL Server Management Studio 2008 user interface only allows you to create a backup of a database to one of the local drives of the database server.
To create a backup of a Microsoft SQL Server database to a location outside of the database server execute the following SQL script:
DISK = N'\\MyNas\MyDatabase.bak'
WITH NOFORMAT, NOINIT, NAME = N'MyDatabase Database Backup', NOSKIP, STATS = 10
Change the bold values to match your environment.
When you write a post or create a page you may want to add sample program snippets to it. If your code contains double quotes (“) the WordPress page will display different characters for the opening and closing quotes, like in this “example”.
Unfortunately these characters differ from the quotes you use for programming, so if someone pastes the sample code into a code editor the compiler will not understand them.
To force WordPress to display your lines as those were intended
- Paste the sample code into the article in Visual mode
- Switch to Text mode and place <code> and </code> tags around the code snippet
HTML or XML
When you insert HTML or XML code into you page make sure you keep the order described above. The visual editor will convert the < and > characters to < and >, so the WordPress engine will not interpret your sample code as part of the HTML of the page.
If you enter the following in Text mode
WordPress will remove your < and > characters and the page will display
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 Lenovo ideapad z580 laptop
- Press the small “Novo” button next to the power button to turn on the computer and display the Novo Button Menu
- In the Novo Button Menu select BIOS Setup and press Enter
Turn off the UEFI boot mode in the BIOS
- In the BIOS setup select Boot on the top of the screen
- Press Enter on the Boot Mode option and select Legacy Support
- Select Boot Priority, press enter and select Legacy First
Save the BIOS settings
- Select Exit on the top of the screen
- Select Exit Saving Changes and press Enter
- Press Enter on Yes to save the changes
The computer will automatically restart into Windows 8
- Keep the power button pressed to shut it down
Boot from the Windows 7 DVD
- Start the computer with the “Novo” button
- Insert the Windows 7 DVD into the DVD drive
- In the Novo Button Menu select Boot Menu and press Enter
- In the Boot menu select 2. ATAPI CD… and press Enter
Install Windows 7
- The computer will boot from the Windows 7 DVD
- Select Install, Advanced installation
- Delete all partitions on the hard drive
- Create one partition (Windows will create another 100MB system partition for itself)
- Select the large partition as the destination of Windows 7
To enable jQuery intellisense in Microsoft Visual Studio
- Open the _references.js file in the editor by double clicking it
- Drag the jquery-x.x.x.intellisense.js file into the _references.js file in the editor. The name of the file will be added to the _references.js file
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.
Create the conditional compilation symbol in the project
- Right click the project
- Select Properties
- On the left side select the Build tab
- Select Dev in the Configuration dropdown
- Enter new_version into the Conditional compilation symbols field
Add the conditional compilation symbol to the source code
- Surround the old and new code with a #if, #else, #endif structure
// New code
int a = 1;
// Old code
int a = 0;
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
There are some settings that can make your work easier in Visual Studio.
Start Microsoft Visual Studio, and in the “Tools” menu select “Options”
– To insert new tabs to the right of existing tabs and keep the already opened tabs in place and
– Show pinned tabs in a separate row
- On the left side select “Environment”, “Tabs and Windows”
- Check “Insert new tabs to the right of existing tabs” and “Show pinned tabs in a separate row”
– To use tabs instead of spaces in edited files
- On the left side select “Text Editor”, “All Languages”, “Tabs”
- Select “Smart” and “Keep tabs”
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:
- Removed the setup project from the solution
- Renamed the setup project file by changing one character of the file name (not the extension)
- Re-added the setup project as an existing project
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:
- By creating a child theme you maintain the changed files in a separate theme (the child theme) so when you update the original (parent) theme your customization is not affected.
- You keep a separate copy of your changes in the child theme, so you can always easily find your modifications without reading through the theme files. You will only maintain the changed lines from the style.css file and your functions.php file will only include your custom functions. Your images folder will only contain your image files.
In this tutorial we will create a child theme for the Simplify theme
- Use your favorite FTP application (mine is FileZilla) and create a folder for the child theme in the wp-content/themes folder
- Right click the “themes” folder and select “Create directory”
- Enter the name of the folder of the child theme
- Double click the new folder name to open it
Right click the empty area of the directory listing and select “Create new file”
Enter style.css as the file name and click OK
- Log into your site as administrator,
- Navigate to the Theme Editor,
- In the upper right corner select the child theme and click the Select button
- In the upper right corner click the “Stylesheet” to open the style.css file
Copy the following to the editor window.
- Enter the name of the new child theme to the “Theme Name” line
- Replace “simplify” with the name of the original theme folder.
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/
- Click the “Update File” button to save your changes
Select and activate the new child theme
- On the left side select “Appearance” , “Themes”
- On the theme list click the empty image of the new child theme you just created
- Click the “Save & Activate” button to activate the child theme
