him . (Connectiong to LogIn)
I did a search in the web an again i found nothing .
Please Help me , Rony
My Code is :
#region SaveStreamToFile
/// <summary>
/// Saves the stream on the HD to the path provided.
/// </summary>
/// <param name="filePath">Where to save the file. (includes the
file name)</param>
/// <param name="stream">The stream contains the data to be
saved.</param>
/// <returns>True - Saved successfully. Otherwise False.</returns>
public void SaveStreamToFile(string filePath, Stream stream)
{
// If not all data was provided return false;
//if (string.IsNullOrEmpty(filePath) || stream == null)
// return false;
// System.IO.Stream gzStream = stream; //= new
System.IO.Stream()//(stream,
System.IO.Compression.CompressionMode.Decompress);
FileStream fs = null;
try
{
byte[] inBuffer = new byte[10000];
int bytesRead = 0;
fs = File.Open(filePath, FileMode.Create, FileAccess.Write,
FileShare.Read);
while ((bytesRead = stream.Read(inBuffer, 0,
inBuffer.Length)) 0)
{
fs.Write(inBuffer, 0, bytesRead);
}
fs.Flush();
// return true;
}
catch (Exception ex)
{
throw ex;
// ExceptionPolicy.HandleException(ex, "Global Policy");
//return false;
}
finally
{
fs.Close();
}
}
