Question about Computers & Internet

1 Answer

I'm almost done but there are few problems

I have a stack which inputs an infix algorithm, then when I hit ENTER it converts to postfix then checks if it is legal then if it is legal, then the arithmetic operation solves, else the error dialog message box will occur. But it only happens in one digit positive value. I want it also together with negative value, decimal value, exponential value and more than one digit value... Please help me

It has been almost 17 months, and nobody has helped you.
By now, you probably have failed the computer-course,
and no longer need any help.

How to create a bootable USB using Vista or Windows 7


Having a bootable USB is very essential, especially if you are a Netbook user. Using bootable USB to install an operating system (OS) not only makes the installation faster, but also saves a DVD.Creating or using an USB drive to install Windows operating systems is very easy if you follow the below mentioned steps.

Here we assume that you are using either Vista or Windows 7 to create a bootable USB.

1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.

2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hit Ctrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator.
3. When the Command Prompt opens, enter the following command:DISKPART and hit enter.LIST DISK and hit enter.Once you enter the LIST DISK command, it will show the disk number of your USB drive.
4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.
SELECT DISK 1 (Replace DISK 1 with your disk number), CLEAN, CREATE PARTITION PRIMARY,SELECT PARTITION 1ACTIVE,FORMAT FS=NTFS(Format process may take few seconds),ASSIGN,EXIT.
Don't close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use "D" as my optical (DVD) drive letter and "H" as my USB drive letter.

6. Go back to command prompt and execute the following commands:

D:CD BOOT and hit enter. Where "D" is your DVD drive letter.CD BOOT and hit enter to see the below message.BOOTSECT.EXE/NT60 H:(Where "H" is your USB drive letter)

7. Copy Windows DVD contents to USB.You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

My Network Places applet keeps disappearing and reappearing


Hi,

It sounds very much like the operating system file have become corrupt.

Click on the the start menu and click on run. When the run box pops up type cmd and hit enter.
A command line window will pop up, in the window type sfc /scannow (leave a space between the c and / ) and hit enter. The system will now check for corrupt operating system files.

When its done (and this could take some time) check to see if the problem has been resolved. If it's fixed then job done but if not please post back and I'll give you another command to check the the disk itself.


Good luck.

How can we use the outlook express 6 to check


Open Microsoft Outlook and from the "Tools" menu select "Email Accounts." The email account wizard will pop up.
Choose "Add a new email account" from the list of options and click the "Next" button. Then, select "HTTP" and hit "Next" again. Now you are ready to input information about your Hotmail account.
Select "Hotmail" from the drop down menu at the right. Enter the name that you want to associate with this account in the "Your Name" field. This is the name that appears when you send someone an email from Outlook.
Input your Hotmail email address in the "Email Address" field. Your user name will automatically be filled in when you do this.
Provide the password to your Hotmail account in the "Password" field. Put a check mark in the check box below if you would like for Outlook to remember your password. This will save you from having to enter your password every time you download your Hotmail email with Outlook.
Hit the "Finish" button to complete the setup of your Hotmail account. Now, when you select "Send and Receive" Outlook will synchronize with Outlook. Too see your Hotmail email, select "Inbox in Hotmail" from your list of mail folders.

Java programming


There are 2000 jpeg libraries in Java out there, easily searchable on search engines, sourceforge, maybe versiontracker, and secondly, you're asking for (what should be application-specific -output-; why would you hobble input) crop/resize without hinting at your algorithm? First, get a real programmer....

Java project for college applications? Gee, how about one to take a personality inventory (the INTJ type; only padded out) including areas of interest and make people little public/private spot codes (2D barcodes, like the ones in Japanese magazines) to indicate their type. The camera in a cellphone with J2ME can read the codes, maybe.... The cool part is that they're coupled with either P3P in wikis or java applets that help communicate with that person if you're an type that would otherwise take bothersome human care and preface to communicate.
There are all kinds of little systems you can build to thwart the draggy bits of Alzheimers' etc. with various little expert systems, that come up when you read a science journal (Nature, Science, Dr. Dobb's Journal, JAMA, JVNA....
