Saving files

[rbulph]

Im trying to save files. They save OK the first time, i.e. when theyre created, but I cant successfully save the changes. Heres the code Im using:

Dim TestFileStream As Stream

        TestFileStream = File.Open(FullPath, FileMode.Create, FileAccess.Write)

        Dim serializer As New BinaryFormatter
        serializer.Serialize(TestFileStream, Me.SerializationCol)
        TestFileStream.Close()

In relation to FileAccess.Write the helpfile says:

"Specifies that the operating system should create a new file. If the file already exists, it will be overwritten. This requires FileIOPermissionAccess.Write. System.IO.FileMode.Create is equivalent to requesting that if the file does not exist, use CreateNew; otherwise, use Truncate. ", but the link for FileIOPermissionAccess.Write is broken.

How do I get my files to save properly?

try calling FileStream.Flush before closing the filestream.

try calling FileStream.Flush before closing the filestream.

Makes no difference, unfortunately.

For diagnostic purposes, try saving it to a MemoryStream and see how many bytes were written to it.

Fixed it thanks. I was missing something very simple - too much Christmas spirit on my part, no doubt.
