The general university account will have a userid similar to: awill039 (a contraction of first initial, family name, and three digits) and would have an address of awill039@uottawa.ca. The EECS account will be only for access to computers in the EECS labs. It is not the account used for official university communications even for the ITI 1120 course. All official e- mails will be sent to the university account, and should be checked there regularly. For students with computer science or software engineering as a major, the EECS account will be active for their entire studies. For students in other programs of study, the account will exist only as long as they take courses with the ITI, CSI or SEG course codes. 2.2 Logging in and Logging out The next step is to log in. CTRL-ALT-DEL can be used to get to the login screen. Some students may have generated their EECS account already. If you have not, use the autopass facility (this is both the userid and password).

2 Once you are logged in check the set of icons that you have on the computer (My Documents, My Computer, My Network Places, Recycle Bin, Click Here to Logout, Map Old H drive to Q) [When you are all done and ready to leave, the last thing you ALWAYS do is to log out. Another student could have access to your files if you do not log out. To logout: Double click on "Click here to logout" icon. Do not turn the power off after logout, leave the power on.] 2.3 Notable Features Some notable features of the EECS environment: (click on My Computer to show this) 1. There is a network drive (H), and the local drive (C). Files on C are only accessible from the specific computer during the current session. Files on the H network drive can be accessed from any EECS lab computer (STE 0110, 0130, 0131, 2052, 2060), and also can be accessed over the web. IMPORTANT: the contents of the C drive are reset after logging out. Files on C that have not been copied to the network drive will be lost and there is no way to recover them! 2. For people with USB memory sticks, they will appear as drive F when plugged in. A CD drive is available as drive E. The CD drives are read only, and cannot be used to burn CDs. 3. Other drives are also network drives, but are read-only. EECS software is stored on these drives. 4. There is an icon that says Map old H drive to Q. Prior to 2004, students had PC disk space allocated on a PC server, and a separate disk space allocated on a Linux server for their Linux account. Now, both systems log in to the Samba file space so that files need not be transferred. That this icon does not do anything useful for newly generated accounts. However, anyone who had a EECS account in summer 2004 or earlier may have to double-click on this icon to find their old files, which will appear on drive Q. 5. All EECS computers run virus protection programs that are updated every day. As U. of Ottawa students, you can have access to a free copy of Symantec Norton Antivirus for your own personal computer; it is available from Anyone who plans to use their own computer to transfer files on-line or via diskette, memory stick, CD, etc. to/from the EECS network or plans to connect a laptop computer to the red posts in the cafeteria is strongly urged to have a virus protection program that keeps up to date installed on their system. The virus protection program is also available on CD at the Campus Computer Store (in the Unicentre) and if you show a student card, the only cost is a nominal charge for the CD ($13?)

3 2.4 Show the university s system at This is a web-based system that can be accessed from anywhere. You can also get to this from a quick link from any university web page. Before logging in, point out the Manage Your Account area, and click on the link. Several important features should be pointed out: Change password Set/remove forwarding address will cause to be forwarded to another account, for people with multiple accounts who read on another account. IMPORTANT: Emphasize that the university account must be monitored frequently for official communications from the university, and sent to this account is assumed to have been read, comparable with a letter to your home. If the forwarding facility is used, test it to make sure it has been set up correctly; students will be held responsible for consequences of missed messages sent to the university account. Configure anti-spam tool: spam is unwanted, unsolicited and that it is a serious problem that can fill your disk space allocation and waste valuable time. Log in. The userid and password as the same as InfoWeb; normally, this would be the student number and PIN issued at registration. Log out when you are done. 2.5 Virtual Campus Go to the Virtual Campus. You can go there immediately from a quick link, or directly via A busy web page with an inconspicuous login area in the upper right corner will appear. Log into the Virtual Campus. The userid and password should be the same as the ones for uozone. Everyone should have the ITI 1120 course on their list. A Course Material page can be accessed from the menu heading Course Material (located beside a binder icon). Clicking on this selection will open a WEB site that contains all course material, including course announcements, course notes, lab material, etc. Navigate to the Laboratories page to get access to a number of files used in this lab. Download all files for Lab 0 (they shall be used in subsequent sections of the lab) You will also notice files available for future labs. The discussion forum is where messages can be posted and seen by everyone in the course. If anyone has technical questions during the course, they should post the question there. All students, teaching assistants, and the professor can contribute replies. Please note that the use of the discussion forum, as with all use of university s computer facilities, is subject to the

4 university s code of user conduct, which is available at Assignments are manages using the Virtual Campus assignment tools (click on Assignments in the menu). A practice assignment is available and will be used later in the lab session. You will note in the lab manual that all files created for assignments must be stored in a directory which has the form A?_xxxxxxx, where? is replaced with an assignment number, and xxxxxxx is replace with your student number. Create the directory A0_xxxxxxx (substituting xxxxxxx with your student number) now. You will find in the assignment tool for Assignment 0, an number of files; download this files onto your hard drive. Place A0Q1.doc and Hello.java into the A0_xxxxxxx directory you just created. 3 Using Microsoft Visio to Draw an Algorithm Body Microsoft Visio is designed for creating drawings. Later in the course you shall be creating algorithm bodies that require the manipulation of a number of symbols to represent instruction blocks, tests, connection points, etc. all connected using connecters to show the flow of the logic of the program. You shall practice using Visio in this first lab (you do not need to understand the diagrams at this point). To get going: Start Visio and create a new drawing with File New Drawing (do not select one of the suggested drawing types). Then open the stencil ITI1120Algorithm which you downloaded from Virtual Campus (use File Shapes Open Stencil ). A stencil with all shape you require will appear is a window on the bottom left hand corner. Simply drag and drop the shapes from the stencil window to the drawing page. Follow the TA instructions to create two images given in question 1 of Assignment 0 which will then by pasted in a Word document (A0Q1.doc). 4 Compiling and running first Java Program using Dr. Java You will be using the Dr. Java environment this term. To start Dr. Java, from the Start menu, select Programming Editors and Dr. Java will appear on the submenu. The startup window of Dr. Java looks like:

5 WARNING: Double-clicking a.java file will NOT open Dr. Java (unless you set this up manually). Instead, Microsoft Visual Studio.NET will start up. Always start Dr. Java first, and then open a file from inside Dr. Java. Here is a simple exercise: 1. Save the files Hello.java and ITI1120.class in the directory A0_xxxxxxx. Start Dr. Java and open the file Hello.java. This is a small Java program with comments. Change the comments with your name and student number. Save the file. 2. Compile the Hello.java file by clicking on Compile in the tool bar.

6 3. Run the Hello.java file by clicking on the Run button in the tool bar. The program will run in the console at the bottom of the window enter your name as requested. 5 Creating and Submitting an assignment Carefully read the section in the lab manual on how to submit an assignment if you have not already. For practice assignment 0, you should have in the directory A0_xxxxxx (xxxxx is your student number): The file A0Q1.doc that you created during the Visio Exercise. Open and create a new Microsoft Word file A0Q2.doc. From Dr. Java, select all the text of the Hello.java program, and copy-paste it into the new Microsoft Word document. Be sure that the font Courrier new with a point size of 10 is used for the inserted Java code. Save the Word document as A0Q2.doc. You should also have the following Java files in the directory: Hello.java, Hello.class, and ITI1120.java Right-click on the A0_xxxxxxx folder and then select Add to A0_xxxxxxx.zip. This will create a zip file with the contents of the directory. Return to Virtual Campus Find and open Assignment 1 tool (either via the Assignments entry in the menu or the Assignments icon in the home page). A page with the title Edit Submission: Assignment 0 shall appear. Click on the button Add Attachments and follow instructions to upload the zip assignment file.

7 ATTENTION: the assignment has not yet been submitted. Click on the button Submit at the bottom of the page. You will see a confirmation that the assignment has been submitted. Return to the assignment tool you should now see a page with the title Assignment Submission: Assignment 0. The assignment can be removed and then re-submitted until the deadline time is reached. At that point, the assignments are locked in, and the TAs will start grading. The TAs will not be able to grade an assignment until after the deadline. 7. Finishing up Remember that the labs are compulsory, and that you have to go to the section to which you have been assigned. There will be a quiz at the end of each lab session. To finish off, any files you have on the C disk including those in My Documents need to be copied over to the network drive or a USB memory stick. Then, double-click on the logout icon. Do not turn off the power.
