Array in an array
#9
@NasaCow here is a sample Student UDT that can hold scores to 20 tests and do 20 Projects details with updated subs and functions to store array data into a Fixed string that can be saved to file because all UDT data is fixed size ie, no variable length strings.
Code: (Select All)
Type NameListType 'Used for the student name database
    PinYinName As String * 20
    FirstName As String * 20
    MiddleName As String * 20
    LastName As String * 20
    Year As Integer
    Month As Integer
    Day As Integer
    HouseColor As String * 8
    MomName As String * 30
    MomPhone As String * 20 'Saved as string to support symbols and international prefixes
    MomEmail As String * 38
    DadName As String * 30
    DadPhone As String * 20
    DadEmail As String * 38
    'UID As Integer ' still need??    Don't think so because tests and projects stored with eacg student
    ' But do have ProjectCode for connecting details of each project assigned
    Tests As String * 60 ' 20 tests 3 chars per score
    ProjectCodeID As String * 60 ' 20 codes at 3 chars per code this could hook up to the Project Details
    ProjectPts As String * 60 ' 0 to 999 points per project allows max 20 projects
    ProjectFlags As String * 60 ' 20 flag codes up to 3 digits each
    ProjectFlags2 As String * 60 ' 20 more flag codes ???
    ProjectNotes As String * 10240 ' thats 512 per comment, allows 20 comments for each of 20 projects

End Type


' test revised sub and function Put3 and Get3$
Dim studentTest3X20 As String * 60 ' fit 20 tests   into fixed string that can be stored from UDT

Data 100,82,75,98,66
For i = 1 To 5 ' test PutTest loading the student test string with 5 tests
    Read testscore
    Put3 studentTest3X20, i, testscore
Next

' ok read back scores  in reverse order
For i = 5 To 1 Step -1
    Print Get3$(studentTest3X20, i)
Next



' 5 types above put 3 digit integers into a string that is holding data like an array
Sub Put3 (DataString As String * 60, Index As Long, IntItem As Integer) ' store 3 digits integers into a string of 20
    Mid$(DataString, Index * 3 - 2, 3) = Right$("   " + _Trim$(Str$(IntItem)), 3)
End Sub

Function Get3$ (DataString As String * 60, Index As Long)
    Get3$ = Mid$(DataString, Index * 3 - 2, 3)
End Function

' For space hog comments
Sub PutProjectNote (DataString As String * 10240, Index As Long, Note As String * 512) ' store 512 note into big string
    Mid$(DataString, Index * 512 - 511, 512) = Note
End Sub

Function GetProjectNote$ (DataString As String * 10240, Index As Long)
    GetProjectNote$ = Mid$(DataString, Index * 512 - 511, 512)
End Function

So you can store the students tests and project details with each Student File and the details of each project in another file and use a Project code number to connect the student data on project to details of project.
b = b + ...
