vb: how to read and write array?
The following is the way to read and write array in visual basic programming:
Private Sub Command6_Click()
Dim LinesArr() As String
ReDim LinesArr(50)
Dim tmp As Integer
Dim LinesRead As Integer
LinesRead = 0
Open App.Path & "\sorteddate.txt" For Input As #1
Do While Not EOF(1)
If LinesRead = UBound(LinesArr) Then
ReDim Preserve LinesArr(UBound(LinesArr) + 50)
End If
'read a line
Line Input #1, LinesArr(LinesRead)
LinesRead = LinesRead + 1
DoEvents
Loop
'redim to actual size
ReDim Preserve LinesArr(LinesRead - 1)
Close #1
For tmp = 0 To UBound(LinesArr)
MsgBox LinesArr(tmp)
Next tmp
End Sub
Use of static array as follows:
Dim tmp As Integer
tmp1 = "001121"
tmp2 = "001122"
tmp3 = "001123"
Dim mArray, mDay
mArray = Array(tmp1, tmp2, tmp3)
' Return values assume lower bound set to 1
' (using Option Base statement).
'mDay = mWeek(2) ' mDay contains "Tue".
'mDay = mWeek(4) ' mDay contains "Thu".
For tmp = 0 To UBound(mArray)
MsgBox mArray(tmp)
Next tmp
