"Hello World!" HTML Document

Introduction:

I decided to do this tutorial because the idea of becoming a developer, specifically a Web Developer, is growing more and more popular. This tutorial will show you how to create a basic HTML document that simply outputs "Hello World!".

Preparation:

The only thing you will need for this tutorial is a simple text editor, we will use Microsoft Windows Notepad because it is available on all Windows PCs. I must point out why I said "simple" text editor. I said this because you will need to make sure the editor does NOT format the document in any way. It must remain in plain text for the browser to be able to read it and identify the code.

Step 1:

Open Windows Notepad. Notepad can be launched from the start menu at this location: All Programs -> Accessories -> Notepad.

Step 2:

Once you have Notepad open, copy / paste the following HTML structure code. I will not go into detail about what this code does or how it works for now. If you do find yourself interested, visit the W3C Schools HTML Tutorial here. This tutorial is great for beginner and intermediate HTML developers.

<html>
<head>
<title>Hello World!</title>
</head>
<body>


</body>
</html> 



Please note that the space in between each body (highlighted above) tag is intentional. It isn't required, but makes things a lot easier for this tutorial.

Step 3:

After you have pasted the code above into the blank Notepad document, we can move on to the cool part! Take the following string and place it in the space we left in between the <body> tags above.

Hello World!

Once you have done this, save your document as 'index.html'. You can save this document by clicking 'File', then 'Save As'. Please note that you must change the file extension drop down box to say 'All Files'. Then click 'Save'.



Finally:

Open your favorite web browser. Once it has loaded your home page, we must open our Hello World! document. In Internet Explorer and many 3rd Party browsers, this can be done by pressing the keyboard binding Ctrl + O. These keys must be pressed at the same time. Alternatively, you can click File - > Open.

In the dialog that appears, choose 'Browse'. Then navigate to your documents folder and choose index.html. Choose Open, then Ok.

There it is! our Hello World! HTML document.

Conclusion:

Anyone can become anything they want to be, including a software developer. What we just did in this tutorial is HTML programming at it's most basic level. If you are interested in learning more about this language and / or wish to become a more advanced HTML developer, I highly recommend you follow the W3C Schools HTML tutorial located here.

Change your Windows Logon Screen Background

Introduction:

In this tutorial, I will guide you through the very easy process of changing the background image of your Windows Logon Screen. I will start with the method for Windows 7 because it is the newest OS from Microsoft, but will finish with the method for Windows XP, because it is the most popular.

Preparation:

You will need a few things before we continue.
  • A JPEG (.jpg for Windows 7, .bmp for Windows XP) image that you want to make your new Logon Screen Background. Please note that this image is limited to 250KB in size.
  • This .REG (compressed in .rar from intowindows.com )  file that will be used to create the proper registry settings ( for Windows 7 users )
  • An Administrative Account.
If you are a Windows XP user, please scroll down to the heading 'Windows XP'.


Windows 7 

Step 1:

The first and probably most important part is to merge the settings located in the .REG file I mentioned above to the Windows Registry. To do this, navigate to the location you saved the file. After you are there, double click, choose 'Yes' on the Permission Prompt. Then, choose 'Yes' to continue, and 'OK' after t has completed.

Step 2:

After the settings have been merged to the registry, navigate to 'C:\Windows\system32\oobe' and create a new folder called 'Info'. Create yet another folder called 'backgrounds' inside the Info folder.

Finally:

Copy the image you chose above to the folders you just created. The structure should look similar to this 'C:\Windows\system32\oobe\Info\backgrounds\YOUR_IMAGE.jpg'

That's it! Now, when you restart, shutdown or boot up this image will be displayed on the Logon Screen!


Windows XP

Step 1:

Click 'Start', then 'Run'. In the 'Run Dialog Box', type 'regedit'.

Step 2:

After the Windows Registry Editor has opened, navigate to the following key by expanding the boxes to the left. 'HKEY_USERS\.DEFAULT\CONTROL PANEL\DESKTOP'

Step 3:

After you have expanded the correct keys, you will see several values, one of which is called 'wallpaper'. Double click that value to edit it's content. In the box that appears, type the full path to the image you chose above. i.e 'C:\Documents and Settings\USER\My Documents\My Pictures\IMAGE.bmp'  This assumes your username is USER and your image is stored in My Pictures and is named IMAGE.bmp.

Finally:

Click OK and close the Registry Editor. Now, when you logoff, shutdown, restart or logon... you will see your image instead of the default Windows XP image!

Conclusion:

Most people don't realize how easy it actually is to make changes like this. Now that you have changed this, what will you change next?

Convert and Resize Images Free Online

Introduction:

This is the second tutorial posted here. The first one applied mainly to IT Pros, so I figured this one should apply to even the most basic computer users. This tutorial will guide you through the process of converting and resizing an image online free using CoolUtils Online Image Converter.



Preparation:

To use this converter, you must obviously have an image you wish to convert and/or resize. After you have chosen your image, open your browser to http://www.coolutils.com/online/image-converter/ .



Step 1:

Once the web page is loaded, choose the 'Browse' button to locate your image. This converter supports all the major formats, and then some. This makes it easy for users to use it because they don't have to worry about what image format their current image is in. After locating your image, select 'Open' to begin the uploading process.



Step 2:
After the image has finished uploading, choose the format you wish to convert your image to. Just like Step 1, it supports all the major image formats.

You can also resize your image by choosing 'Resize' to the right of the conversion format selection box. Enter the width and height that you want your image to reflect. Please note that it is possible to increase the size of your image, but highly Not recommended. When an image is increased in size, it stretches the pixels to accommodate the new size, thus the image becomes blurry.

Rotation of your image is also available, but that is self explanatory, so we won't go into that now.



Finally:

After you have chosen the option and format you want, chose 'Download Converted File' to get your new image in it's new format and size!



Conclusion:

Who ever said image conversion and resizing had to be a pain? With new utilities and free tools like the CoolUtils Online Image Converter, it streamlines the task and makes it more bearable! This tool doesn't leave any watermarks or claim ownership of your file, so you can do what you wish with the finished image! You are allowed to use this tool an unlimited number of times without a waiting period between conversions.

If there were an award for "Best Image Conversion" or "Best Free Online Tools", I think it should definitely go to CoolUtils!

Create a Bootable MS DOS USB Flash Drive

Before I knew the easy way of turning an ordinary USB Flash Drive into a Bootable USB Drive with the MS DOS operating system, I searched for hours looking for a good tutorial that worked.  This is good for those who need to perform tasks such as flashing BIOS and other tasks of that nature.
This tutorial will guide you through this process, and provide links to the relevant resources and tools you'll need.

Preparation:

You will need the HP USB Disk Format Tool to perform the actual "transformation". You may download that here. Download and install this tool.

You will also need the Windows 98 Setup files, which can be found here. Download these files and save them to a spot you'll remember. Usually saving it in My Documents (or Documents in Windows Vista and 7) is the easiest place to remember.

A USB Flash drive will be required. If you currently have data on the drive you would like to use, you will need to back that data up because the drive will be formatted and all data will be erased. I recommend using at least a 2GB drive.

Step 1:

Insert your USB Flash Drive into an available USB port.

Launch the HP USB Disk Format Tool by clicking it's icon on the desktop, or the Start Menu. If you are running Windows Vista or 7, you will need to run this program as an Administrator by right clicking the icon and choosing "Run as Administrator".

Step 2:

Once the tool has loaded, select the drive letter of your USB Flash Drive. If you are unsure which letter is the USB drive you want to use, the easiest way to check is to open My Computer ( Computer in Windows Vista and 7 ) and locate the USB drive you want to use. The letter displayed next to the label of that drive is the one you want to select in the HP Disk Format tool.

Beware of which drive you select as that drive will be formatted!!

Step 3:


After you have chosen the correct drive letter,  choose 'FAT 32' as the file system, then check the 'Quick Format' box to save a little time.

Now, we need to specify the Windows 98 System files we would like to use. Check the 'Create a DOS Startup Disk' box, then choose the '...' button and browse to the location you saved the Windows 98 System Files. Choose the folder that contains the system files, then choose 'OK'.

Your window should look similar to this now:


Final Step:

Press 'Start' to turn your USB Flash Drive into a bootable USB MS DOS Disk.! This may take a few minutes, depending on the size of the drive. After this completes, you are finished and can now boot your MS DOS USB Drive!!

Conclusion:

That's it! You have now just created your very own bootable MS DOS USB Drive!
