• Final grades, comments, etc. are posted. If you feel I made a mistake on yours, please let me know so that I may check it before grades are turned in either late Monday or Tuesday.

• Homework 5 is due on Tuesday May 4, 2004 not Sunday May 2 and Sunday May 6 as originally posted.

• Homework 5 is now posted.

• Office hours for the remainder of spring semester will be:
  
  Wednesday and Friday 10:00 a.m. to noon.

• Grades and comments for homework 3 are posted.

• Office hours for the remainder of the semester will be changed to Wednesday and Friday mornings. Check Office Hours  later today for specific times.

• The due date for homework 4 is now Tuesday April 6, 2004. Hope the extra time helps.

• Smuckers announced seven summer internships. Take a look at http://asgard.kent.edu/internships. Click on the "Job Openings" link for details.

• A clarification on homework 4.

  When you create your dialog form with the OK and Cancel buttons, you need to be careful about one thing. Setting the form's AcceptButton property to btnOK, or some other button, will simultaneously set the DialogResult property for btnOK, or the other button, to the value DialogResult.OK. When any button's DialogResult property is set to a value other than the default None, clicking that button will cause the form to close and the appropriate Dialog.Result value to be returned by the ShowDialog method. If you find that clicking a button on the dialog form is not closing the dialog form, most likely the problem is that the DialogResult property for that button has been reset to None. Change it to the appropriate value and the next time you click the button, the dialog form should close.

• Homework 4 is now posted.

• Change in Homework Submission Procedure

  Because of the Bagle virus attack, you need to change the method you use to submit your homeworks. The new method is:

  1. As before, create a zip file that contains your entire solution. (All of the files, folders, etc. that are a part of the solution.)

  2. Upload the zip file to WebCT, being certain that you place it into the correct folder for that homework.

  3. New Step: Click the CheckBox next to the name of the zip file you just uploaded. From the drop down list box at the top of the window, select the action to Unzip the selected file. Click the Go button next to the drop down list box. At the next page, click on the drop down list box. You should see a display that is similar to the following:
     
     
     
     Select the correct homework folder and click the Unzip button. If all goes well, you will see the files and folders for your solution reflected in the homework folder on WebCT.

     If you do not unzip your folder, I will not do it for you. This means I will not grade your homework. Even if you have an infected zip file, no damage should be done as the Bagle virus infects PCs running Windows. Since WebCT is a Linux box, it is immune to the Bagle virus.

  If, after initially submitting your homework, you wish to submit a revised homework, do the same thing. Upload the new zip file and unzip it. Assuming you have not changed any file or folder names, the original files and folders will be overwritten during the unzip process.

• The due date for homework 3 is changed to Wednesday March 3, 2004.

• With respect to the question raised in class, on the Left method for homework 3, the following should apply based on the value of howmany:
  • If howmany is less than zero, then an ArgumentException should be thrown.

  • If howmany is equal to zero, the method should return the null string "".

  • If howmany is greater than the length of sourcestring, then sourcestring should be returned.

  • If howmany is some other value, then howmany characters of sourcesting should be returned by the method, starting with the first character.

• Grades and comments for homework 2 are posted. If you feel there is a problem with your score, please let me know so I can check to make certain I graded it correctly.

• Homework 3 is posted.

• I mentioned in class that you could write a procedure to Clear all TextBoxe that are a part of a form in a manner that would allow you to avoid having to change the code as TextBoxes are added to/removed from the form and/or renamed. Here's the code for a Button Click event to accomplish this.

  private void button1_Click(object sender, System.EventArgs e)
  {
    foreach (Object X in this.Controls)     // get each Object on the form
    {
      //  if the Object X is a TextBox
      if (X.GetType().ToString() == "System.Windows.Forms.TextBox")
      {
  	  TextBox T = (TextBox)X;        // convert Object X to a TextBox
  	  T.Clear();                     // Clear the TextBox
      }
    }
  }
  

• I forgot when we decided on C# as the programming language to change this page to point to the C# Programming Rules. You can find them at C# Programming Rules or by following the link to the left.

• The PowerPoint show third.ppt is now available.

• And, IntroCode.txt has been updated to include the code from this show that can be copied into DemoProg.cs to execute.

• You can download Second.ppt, the second PowerPoint slide show we've been going over.

• And, the file IntroCode.txt, which contains C# source code ofr all the samples. It can copied using NotePad and pasted into the DemoProg below to illustrate what's happening in C#.

• Homework 2 is posted.

• A few minor changes were made to the first PowerPoint presentation. You might want to download the newer version of intro.ppt.

• The zip file DemoProg.zip contains source code for a simple program that can be used to test out the C# examples given in the first PowerPoint slide show. You can download this zip file and expand it into the folder DemoProg. Load the solution file into Visual Studio. Then you can paste the sample code in the method btnDoIt_Click at the indicated point.

• Download the file IntroCode.txt. It contains the C# code from the examples and is probably easier to use as a source for the code than the actual slides.

• You can download intro.ppt, the PowerPoint presentation that was started on Thursday.

• I've been doing some web surfing and have come up with several interesting links to C# tutorials. Both assume you know how to program (a good assumption, I trust) and have some background in C, C++ or Java (not as good an assumption). I think you'll find them to be helpful.

  The second link appears to be NetScape hostile. I suggest using InternetExplorer to look at either.

  With a little time, you could find similar sites that mmightbe superior to these. If you do, let me know and I'll include links to them on the web.

• Grades for the first homework are posted to the web.

  If you do not see a grade for your grade identifier, that means you have not done it. If you do it by midnight January 16, 2004 and send me an email saying you are in 24070 and have uploaded homework 1, it will be graded. If you do not do this by then, a score of zero will be entered for you for homework 1.

  Welcome to the M&IS 24080 homepage. You should check it frequently for announcements relevant to the course.
  • Homework 1 is due Wednesday January 14, 2003 before 3:00 p.m.

  • You must have WinZip, PKZip or another package that compresses folders in order to turn in all homeworks, except for the first. You can get WinZip at http://www.winzip.com/. PKZip is available at http://www.pkzip.com/.

  • When you submit homework 1, you should see a file named gradeid.txt in the folder hw01. If you edit this file, you'll find a four digit identification number in it. This number can be used to identify your grades on the grades page as they are posted.

  • You'll hear it from me frequently. But, it bears repeating.

    Do not procrastinate. Get an early start on all homeworks for this course.
