>Hi all,
In VB6, I could use the API too query the size of a file on the web, then
download that file showing a custom progress indicator. I realize that I
can use the DownloadFile method and show a UI, but I would like to indicate
progress in my own form instead. In VB2005, how can I first get the
filesize of the web image (a tif file), then stream that image (as an array
of bytes??) to a local file while showing progress?
If all else fails, I suppose I could go the API route, but I was wondering
if there was a .Net native way to do it.
Thanks,
Lance
Have as look at the WebClient. I use this to simply download and then display the resulting image.
'Start the download:
WebClient1.DownloadDataAsync(some uri)
'In the WebClient1_DownloadProgressChanged is the "progress value":
MyProgress = e.ProgressPercentage
'In the WebClient1_DownloadDataCompleted event:
Dim myDatabuffer As Byte() = e.Result
Dim ms As New System.IO.MemoryStream
ms.Write(myDatabuffer, 0, myDatabuffer.Length)
bm = New Bitmap(ms, True)
Dim iWidth As Integer = bm.Width
Dim iHeight As Integer = bm.Height
PictureBox1.Image = bm
