lblStatus.Text = $"{e.ProgressPercentage}% - {receivedMB:F2} MB / {totalMB:F2} MB - Speed: {speedKbps:F0} KB/s"

Using client As New HttpClient() Try Dim response = Await client.GetAsync(url, HttpCompletionOption.ResponseHeadersRead, _cts.Token) response.EnsureSuccessStatusCode() Dim total = response.Content.Headers.ContentLength Using stream = Await response.Content.ReadAsStreamAsync() Using fs = New FileStream(savePath, FileMode.Create, FileAccess.Write, FileShare.None, 8192, True) Dim buffer(8192) As Byte Dim read As Integer Dim totalRead As Long = 0 Dim lastPercent As Integer = 0 Dim sw = Stopwatch.StartNew() You will need: lblStatus
