I am trying to take binary data and save to create a PDF. I think the
problem is the size of the data. Any ideas for a workaround? I am using
vb.net in asp.net

Dim BinaryStream
BinaryStream = CreateObject("ADODB.Stream")

'Specify stream type - we want To save binary data.
BinaryStream.Type = adTypeBinary

'Open the stream And write binary data To the object
BinaryStream.Open

BinaryStream.Write(ByteArray)

'Save binary data To disk
BinaryStream.SaveToFile("e:\websites\testfile.pdf')

I am getting an error: on the .Write command

Arguments are of the wrong type, are out of acceptable range, or are in

Use System.IO.FileStream class to write bytes directly into a file
http://msdn2.microsoft.com/en-us/library/system.io.filestream.aspx

It has a Write method which accepts a byte
array(http://msdn2.microsoft.com/en-us/library/
system.io.filestream.write(VS.80).aspx)

Example:

Dim byteData() As Byte

Dim oFileStream As System.IO.FileStream
oFileStream = New System.IO.FileStream("testfile.pdf",
System.IO.FileMode.Create)
oFileStream.Write(byteData, 0, byteData.Length)
oFileStream.Close()
