BytesMax

Returns the total number of bytes expected for the read, as a Long. Read-only.

Syntax: object.BytesMax

object

required An object expression that evaluates to an AsyncProperty object.

Used together with BytesRead to update a progress indicator during an AsyncReadProgress event. BytesMax can be zero when the server has not advertised a content length --- for example with an HTTP chunked transfer --- in which case the total size is not known until the read completes and a determinate progress bar cannot be shown.

Example

This example shows progress as a ratio when the total size is known.

Private Sub UserControl_AsyncReadProgress(AsyncProp As AsyncProperty)
    If AsyncProp.BytesMax > 0 Then
        Dim pct As Long
        pct = CLng(AsyncProp.BytesRead * 100 \ AsyncProp.BytesMax)
        ProgressBar1.Value = pct
    End If
End Sub
