I have created a class called Student, with five private variables: [code] My main form is divided into a number of different sub procedures. In one of them, I used a streamreader to take the first name, last name, and phone numbers of a list of records in a text file called PersonalInfo.txt. It seems to work just fine. [code] I have another, separate sub procedure in which I read a different text file containing the "averages" for the students. The first average from Averages.txt belongs with the first student in PersonalInfo.txt. The second average goes with the second student.. How do I add the student average information to the properties of the student records created in the previous sub procedure? [code] I realize why this wouldn't work, but I can't figure out how I could use my counter to reference a specific student.

I created a simple Class called Student.[code]And then I tried to create an array of Students called s. I'd like to do something simple with the names of one of the students like the following..[code]I know that I need to use the New keyword to create an instance for each s(), but I'm not sure where to put it. When I try it without the array it's easy.
View 2 RepliesThe idea of this program is to calculate and find total and average for 3 Students automatically. That is when the first data is entered and click on button the total and average of first student should be displayed in listbox. And we should be able to enter second data. Bu the problem is it is just printing the first average and total thrice.
Dim a As String
Dim tot, avg, N As Single
Dim I As Integer
For I = 1 To 3
tot = Val(TextBox2.Text) + Val(TextBox3.Text) + Val(TextBox4.Text) + Val(TextBox5.Text) + Val(TextBox6.Text)

View 7 RepliesOk I have a search Button that will search through a student table and produce the grades of all the stdents in a class room when I enter the class room number into a textbox(txtclass.Text). The results will be displayed in a DataGridView and also I have the average grade of the class displayed in another textbox(marks.Text).
My program runs fine but I would like to add more code so that If I enter a wrong classrom number into the search textbox and Search for it then I would like a messagebox to pop up and say that the classrom you have entered does not exist. .I have tried different if statements but none has worked for me so far.

I'm reviewing a midterm visual basic exam question that I got didn't code correctly and I cannot figure out what I'm doing wrong.
The problem is:"Figure 7.4 contains an array of survey responses that is hard-coded (1-5) into the program. Suppose we wish to process survey results that are stored in a file. First, create an application that enables the user to write survey responses to a file. Use StreamWriter to create a file called SurveyResponses.txt and write each response on a separate line. Modify the code in fig. 7.4 to read the survey responses from SurveyResponses.txt by using StreamReader. THe program should continue to read responses until it reaches the end of file. The results should be output to a text box."
Note:the output of figure 7.4 is as follows and the frequency is incremented when a user submits a response.
Rating Frequency
1
2
3
4
5
My issue is that I use StreamReader and StreamWriter to allow the user to select a location to save the file and to open the file. I believe VB must automatically create a file and automatically open it, which I cannot figure out how to do it.

View 2 RepliesI'm planning my road in VB training on my own at home using various books and online resources, like MSDN and book publisher support sites, etc. My initial goal is to become familiar w/the VB 2008 language but then to build upon that w/other skills like perhaps, ASP.

Not only that, what should my learning "list" look like, assuming it a good idea to "add" to the lot w/other VB skills? What's a "real world" learning plan look like in VB? Which should I consider to be "priority" core VB skills to learn after initially learning the VB language?What is a realistic VB skill portfolio look like?

I want to create small database which handles Student Attendance Record it will store the roll calls of students on daily basis that teachers collect from the students in the class on paper and then later transfer it on computer .So my database Must contain Month, Year, Program (BCS, BIT, MS, MCS, MIT etc) Batch (1st, 2nd etc) and Subject (English, Math, Geography etc)
Suppose I want to Search for the Attendance Sheet of any month, year, Program, Batch or Subject, it returns me the required dataSo i come up with the Datadase which includes 5 dimension tables and one fact tableDimension Tables1. Student (StudentID, Name, other Attributes)2. Program (Program_Name, other Attributes)3. Date (Date, Week, Month, Year)4. Batch (Batch_Number, Description)5. Subject (Subject_Name, other Attributes)Fact TableAttendanceTable ( StudentID, Program, Date, Batch, Subject, Status)but the problem come when certain columns are repeating again and again which is time consuming for database operator and shows inconsistent behaviour of database.
Look at it: my Fact table would be like this [code]....
problems:1. The StudentId is repeating which shouldn't (Primary Key),2.It wastes a lot of time coz i'm repeating the data again and again Like Program, Date and Batch which shouldn't be in consistent Databases.
