Arrays en Loops

1. Arrays - Statisch

Dim cars(2)
cars(0) = "Ford"
cars(1) = "Audi"
cars(2) = "Prius"

2. Arrays - Dynamisch

Dim cars()
Redim cars(0) 'Give it 1 entry
Dim tmp
tmp = "Ford"

'ubound(arrayvariable) is the count of array size.
'in this case, it would be 1, since there is 1 entry. 
cars(ubound(cars)) = tmp 'cars(0)
Redim preserve cars(ubound(cars)+1)

5. Een array maken op basis van een tekstbestand.

Dim cars
Dim filefullname : filefullname = "C:\testenv\test.txt"
'If you can, create an instaneous read for text file data for better memory handling.
'Unless it's a large file and that's impossible. 
cars = Split(CreateObject("Scripting.FileSystemObject").OpenTextFile(filefullname, 1).ReadAll, vbcrlf)

7. Voor elke lus.

U kunt de inhoud van de array niet wijzigen via de lusvariabele omdat dit een tijdelijk element is waaraan elk element wordt toegewezen.

Dim cars(2) 'collection of different cars
Dim trace 'track iteration details
cars(0) = "Ford"
cars(1) = "Audi"
cars(2) = "Prius"
For Each car in cars
    trace = trace & car & " temporarily changed to "
    car = "Jeep" 'affects car but not the cars array
    trace = trace & car & vbNewLine
Next

MsgBox trace 'show what happened during the loop

Dim jeeps : jeeps = 0
For Each car in cars
    If car = "Jeep" Then jeeps = jeeps +1
Next

MsgBox jeeps & " of the cars are Jeeps."

6. Voor lus

Dim i, cars(2)
cars(0) = "Ford"
cars(1) = "Audi"
cars(2) = "Prius"
For i=0 to ubound(cars)
    If cars(i) = "Audi" Then Exit For
Next

8. Doe terwijl lus

Dim x, cars
x = 0
cars = Split(CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\testenv\example.txt", 1).ReadAll, vbcrlf)
Do While x < ubound(cars)
    If cars(x) = "Audi" Then Exit Loop
    x = x + 1
Loop

9. Doe tot lus

Dim copycars(), cars(2), x
Redim copycars(0)
x = 0
cars(0) = "Ford"
cars(1) = "Audi"
cars(2) = "Prius"
Do Until x = ubound(cars)
    copycars(ubound(copycars)) = cars(x)
    redim preserve copycars(ubound(copycars)+1)
    x = x + 1
Loop
redim preserve copycars(ubound(copycars)-1) 'trim off the empty last entry

3. Arrays - Multi-dimensioneel

Dim mdArray(2,3)
mdArray(0, 0) = "test1"
mdArray(0, 1) = "test2"
mdArray(0, 2) = "test3"
mdArray(0, 3) = "test4"
mdArray(1, 0) = "test5"
mdArray(1, 1) = "test6"
mdArray(1, 2) = "test7"
mdArray(1, 3) = "test8"
mdArray(2, 0) = "test9"
mdArray(2, 1) = "test10"
mdArray(2, 2) = "test11"
mdArray(2, 3) = "test12"

4. Arrays - Multi-dimensioneel - Dynamisch

Dim mddArray()
ReDim mddArray(0)
Dim ti, testinc: testinc = "test": ti = 1
For i = 0 To 4
    Dim tmpArray(): ReDim tmpArray(0)
    For j = 0 To 3
        tmpArray(UBound(tmpArray)) = testinc & ti
        ti = ti + 1
        ReDim Preserve tmpArray(UBound(tmpArray) + 1)
    Next
    ReDim Preserve tmpArray(UBound(tmpArray) - 1)
    mddArray(i) = tmpArray
    ReDim Preserve mddArray(UBound(mddArray) + 1)
Next
ReDim Preserve mddArray(UBound(mddArray) - 1)
