Listbox1.heading gives a Listbox1.heading gives a title to the column title to the column designated by the number designated by the number in parentheses. This title is in parentheses. This title is the phrase in quotes.the phrase in quotes.

Students = array says that Students = array says that this array is named this array is named students and the names students and the names following are part of the following are part of the array.array.

Grades = array says that Grades = array says that this array is named grades this array is named grades and the numbers following and the numbers following are part of the array.are part of the array.

The 2 methods put the The 2 methods put the array into the listboxarray into the listbox

The 2 MethodsThe 2 Methods Fillgrades()Fillgrades()dim u, i as integerdim u, i as integer u = ubound(grades)u = ubound(grades)

for i = 0 to ufor i = 0 to u listbox1.cell (i,1) = listbox1.cell (i,1) =

str(grades(i))str(grades(i)) next inext i

Fillstudents()Fillstudents() dim u, i as integer dim u, i as integer u = ubound(students)u = ubound(students) for i = 0 to ufor i = 0 to u listbox1.addrow students (i)listbox1.addrow students (i) next inext i

The 2 methods use ubound The 2 methods use ubound and a loopand a loop

Ubound says to continue Ubound says to continue through the loop until all through the loop until all of the array has been of the array has been added.added.

Listbox1.cell is used to Listbox1.cell is used to add grades because add grades because grades is numbersgrades is numbers

Listbox1.addrow is used Listbox1.addrow is used for students because for students because students are words.students are words.

Another WayAnother Way Dim u,i as integerDim u,i as integer listbox1.heading(0) = "Student"listbox1.heading(0) = "Student" listbox1.heading(1) = " Grades"listbox1.heading(1) = " Grades" students = array (" Juliette", students = array (" Juliette",

Grades = array ( 100.0 , 78.6 , Grades = array ( 100.0 , 78.6 , 100.0, 95.4 , 89.2 , 76.0 , 87.9 , 100.0, 95.4 , 89.2 , 76.0 , 87.9 , 97.0 , 96.0)97.0 , 96.0)

for i = 0 to ufor i = 0 to u listbox1.addrow students(i)listbox1.addrow students(i) u = ubound(grades)u = ubound(grades) next Inext I for i=0 to u for i=0 to u listbox1.cell (i, 1)= str(grades(i))listbox1.cell (i, 1)= str(grades(i)) next i next i

This does the same as the This does the same as the previous way except that previous way except that instead of using methods the instead of using methods the information that was in the information that was in the methods is simply in the methods is simply in the Open event.Open event.

Find AverageFind Average dim u as integerdim u as integer dim k as integerdim k as integer dim result as doubledim result as double u = ubound(grades)u = ubound(grades) result = 0result = 0 for k = 0 to ufor k = 0 to u result =result + grades(k)result =result + grades(k) next knext k u = u +1u = u +1 average.text = str(result/u)average.text = str(result/u)

To find the average a loop To find the average a loop was used and ubound was was used and ubound was used in the loop.used in the loop.

The 1The 1stst grade would be grade would be added to the next and added to the next and become the result. This become the result. This would repeat until the end would repeat until the end of the array was reached.of the array was reached.

u = u+1 had to be added u = u+1 had to be added becase the rows start at 0 becase the rows start at 0 not at 1.not at 1.

The result divide by the The result divide by the number of grades in the number of grades in the array (represented by u) is array (represented by u) is imputed into the editfield imputed into the editfield (here is average.text).(here is average.text).

Each push button was located next to Each push button was located next to or under the editfield it corresponded or under the editfield it corresponded to. For example the button to find the to. For example the button to find the maximum was located directly under maximum was located directly under the editfield in which the maximum the editfield in which the maximum would appear. This was to make it would appear. This was to make it easier to read and use.easier to read and use.
