Writing large text files

[Russ1984]

Hi,

I'm having trouble writing all of a large string to a text file. I have an pdf encoded in MIME's base 64 included in an xml file which I need to store temporarily. I think the problem may be a limit on the capacity of the StreamWriter class but I'm not sure. Here's what I have:

Public Function readPDF(ByVal filename As String) As Boolean
Dim d As New XmlDocument()
Dim sw As New StreamWriter("/temp.txt")
d.Load(filename)
Dim nl As XmlNodeList
nl = d.GetElementsByTagName("Formatted-Report")
sw.Write(nl(0).InnerText)
Return True
End Function

Any help greatly appreciated.

You have to close the writer.

sw.Close()

There is also the Using block that can be helpful:

Using sw As New StreamWriter("/temp.txt")
  sw.write(...)
End Using
