The general rule is "never write back to the source file".

Otherwise, find an upper-class student to help give you a one-on-one tutorial to help you with your homework.

Can't get flash player. Why

That is not how it works.
You click on a link for a video file. The default reader for the file type will start and open/stream the content. If the file extension is not recognized to be a Flashplayer compatible file, the player will not start.

Hi - on log on my computer is unable to open my user account and opens a temporary account instead. It gives the message 'attempting to restore a file in the registry but the specified file is not in...

If you can access your computer with a temporary user account, you can simply replace the "hal.dll". You can find this file in all windows computers (win xp to win 7), simply copy the file from another computer save it on a flash drive and paste it in the folder C: > Windows > System 32 and paste it. The steps are as follows, open "My Computer", double click "C:" drive, again open "Windows" folder and then again open "System32" folder and paste the file there. Restart your computer and it'll work fine.

Or you can download the "hal.dll" file here. (I've uploaded it for you). Open the link and click "Download Now", wait for 20 seconds and again click "Download File Now" link (purple link).

If you need further help, let me know.

Good luck.

Thanks for using FixYa.

Go to start button. In the start menu click RUN and in the box that opens type "cmd"
In the CLI go to the directory of the folder whose content you want to print and type the following and press enter to create list.txt file first before printing.

dir /b /s /on >list.txt

This will give you a text file (list.txt) in the folder, that you
can manipulate, print etc. in a text editor or
word processor. In order to redirect the output
directly to your printer, instead of a text file, type:

dir /b /s /on >prn

Where i can get software for C Programing language and what is the software name...........?

STEP 1 : Download the Borland Compiler
STEP2 : Run the setup program
By default, it should install everything to C:\Borland\BCC55

STEP 3 : Add the /bin directory to the system PATH

>C:\Borland\BCC55\bin\bcc32 OR >c32

After the setup program is run (step 2), a whole bunch of executable programs are placed in a new directory : C:\Borland\BCC55\Bin. This step makes it possible for the Operating System (Windows) to find these new executables by name. If you don't do this, then you will need to specify the full path to bcc32 every time you use it.

To do this on Windows XP
Bring up the Environmental Variables :

•Right Click "My Computer" ( Depending on how your system is set-up, "My Computer" is either on your Desktop or in your Start Menu )
•Select "Properties"
•Activate the "Advanced" Tab
•Click the "Environmental Variables" Button
Append ";C:\Borland\BCC44\bin" to the PATH variable (figure 3-2)

•Select the PATH variable under User Variables
Note: The PATH variable may appear under both System Variables and User Variables. This How-To changes the User Variable.
•Click the EDIT button below the list
•In the "Edit User Variable" box that pops up, move the cursor to the end of the Variable Value field
•Add a semi-colon ";" to the end of the current value
Note: If the value is empty, then you do not need to add a semi-colon
•Add the path "C:\Borland\BCC55\bin" after the semi-colon
•"OK" your way out of the dialogs

STEP 4 : Set up some configuration files
you should create a configuration file for the bcc32 program that tells it where to find its libraries and include files.
•The file should be named bcc32.cfg
•It should be placed in the same bin directory where bcc32.exe is located
•The contents of the file are the command line options for bcc32 stating the location of include files and libraries:

How I can "Decrypt data files" on Win XP Professional.

Since you reinstalled the OS, the certificate for the user has changed. You can try the following methods, but there is no guaranty it will work.
These method apply only if the computer name and users name stays the same as the original. If the machine name or the users name or the users privilege changed, these method will not work.

Only the following people can decrypt an encrypted file:
· The user who encrypted the file
· Any user who was designated as a recovery agent before the file was encrypted
· Any user who has the public key or private key for the recovery agent or the user who originally encrypted the file
· Any user who has been granted access to the file
Members of the Administrators group cannot decrypt files unless the person who encrypted the files designated them as recovery agents before encrypting the files.

Note You must be the original user who encrypted the file or a designated recovery agent for the file to follow these steps

Method 1:
To remove encryption from a file, follow these steps:
1. Use Windows Explorer to locate the encrypted file that you want to decrypt.
2. Right-click the encrypted file, and then click Properties.
3. On the General tab, click Advanced.
4. Click to clear the Encrypt contents to secure data check box, click OK, and then click OK again.
