Deleting Elements in an Array if Element is a Certain value VBA

Question

I have a global array, prLst() that can of variable length. It takes in numbers as strings \"1\" to Ubound(prLst). However, when the

Answer 1

here is a sample of code using the CopyMemory function to do the job.

It is supposedly "much faster" (depending of the size and type of the array...).

i am not the author, but i tested it :

Sub RemoveArrayElement_Str(ByRef AryVar() As String, ByVal RemoveWhich As Long) 

'// The size of the array elements
'// In the case of string arrays, they are
'// simply 32 bit pointers to BSTR's.
Dim byteLen As Byte

'// String pointers are 4 bytes
byteLen = 4

'// The copymemory operation is not necessary unless
'// we are working with an array element that is not
'// at the end of the array
If RemoveWhich < UBound(AryVar) Then
    '// Copy the block of string pointers starting at
    ' the position after the
    '// removed item back one spot.
    CopyMemory ByVal VarPtr(AryVar(RemoveWhich)), ByVal _
        VarPtr(AryVar(RemoveWhich + 1)), (byteLen) * _
        (UBound(AryVar) - RemoveWhich)
End If

'// If we are removing the last array element
'// just deinitialize the array
'// otherwise chop the array down by one.
If UBound(AryVar) = LBound(AryVar) Then
    Erase AryVar
Else
    ReDim Preserve AryVar(LBound(AryVar) To UBound(AryVar) - 1)
End If
End Sub
