STANDARD ALGORITHMS AND ARRAYS
Stage 3 – Implementation
•
•
•
•
Start a new Visual BASIC project
Create a form as above
Name the command button cmdDataEntry
Enter the code for the command button (declaring all required
variables)
• Save the project and form in a new folder.
Stage 4 – Testing
Test the program with some normal test data.
You might well be thinking that
this is a very tedious example, and
that there should be an easier way
of implementing the program...
...and you are right! You should be
thinking ‘Loop!’
This is an ideal situation to employ
a For ... Next loop, as the same
action has to be repeated five times.
Here is simpler version using 2 For..Next loops:
Private Sub cmdDataEntry_Click()
Dim student_name as String
Dim mark as Integer
Dim i as Integer
Note: we can’t call the
variable ‘name’ as ‘name’ is a
VB object property, so we
use ‘student_name’ instead.
For i = 1 to 5
Student_name = InputBox(“Enter a name”)
mark = InputBox(“and their mark”)
Next
For i = 1 to 5
Form1.Print student_name; mark
Next
End Sub
Implement and test this new version.
