 Posted: Sun Jul 11, 2010 3:32 pm Post subject: Load external file - MemoryStream help |
 |
|
Hi,
I am trying to modify this function that load an external file.
Instead of it writing bit by bit to the 'Stream' IOStream, I would like to write the data to a temporary MemoryStream, and then write it to 'Stream' all at once. This should be right before the 'Stream.Close()' line.
Can you help me ?
Here is my current code:
| Code: | Dim FromStream As System.IO.Stream = Nothing
FromStream = GetFileStream(Path)
If Not FromStream Is Nothing Then
Const Size As Integer = 256 * 1024
Dim buffer(Size) As Byte
Dim ReadBytes As Integer
While True
ReadBytes = FromStream.Read(buffer, 0, Size)
If ReadBytes = 0 Then Exit While
Try
Stream.Write(buffer, 0, ReadBytes)
Catch e As System.IO.IOException
' Loading is interrupted
Exit While
End Try
End While
Stream.Close()
Handled = True
End If |
Thanks |

A quick question: before reading from the MemoryStream, have you seek its pointer to the beginning: MemoryStream.Position = 0 ?
Thank you.

Thank you very much,
Sorry for the late reply, but I found the solution.
Now, while the external file is being loaded into temporary memory, I can put a DoEvents in the While and this way the application does not freeze while loading swfs from external dlls (20-30 MB each).
Thanks Razin |
