I want to update entries and get a 400 Error

[GoogleCodeExporter]

Here my sourcecode:

DocumentsService docService = new DocumentsService("mosUniverse-testApp-1");
DocumentsFeed feed;

...

docService.setUserCredentials("email@gmx.de", "Password");
feed = docService.Query(new DocumentsListQuery());

...

AtomEntry entry = new AtomEntry();
AtomPerson author = new AtomPerson(AtomPersonType.Author);
author.Name = "Moritz";
author.Email = "mail@gmx.de";
entry.Authors.Add(author);
entry.Title.Text = "Tennis with Beth";
entry.Content.Content = "Meet for a quick lesson.";

docService.Insert(feed, entry); // Here i get a 400 error.

...

feed.Entries[listBox1.SelectedIndex].Content.Content = textBox1.Text;
feed.Entries[listBox1.SelectedIndex].Update();  // here the same error

The error is:
Execution of request failed: https://docs.google.com/feeds/default/private/full

Could someone help me?
It would be great!

If you check the complete error message, it reads "Entry must contain at least 
one category".
There are many ways to specify the category, you may probably want to add a 
line like the following before you call Insert:

entry.Categories.Add(DocumentEntry.DOCUMENT_CATEGORY);

Thank you very mutch. The upload works now with:

AtomEntry entry = new AtomEntry();
AtomPerson author = new AtomPerson(AtomPersonType.Author);
author.Name = "Moritz";
author.Email = "moritz.goeckel@gmx.de";
entry.Authors.Add(author);
entry.Title.Text = "Tennis with Beth";
entry.Content.Content = "Meet for a quick lesson.";
entry.Categories.Add(DocumentEntry.DOCUMENT_CATEGORY);
docService.Insert(feed, entry);

But the content does not apear online an googleDocs.
What is wrong?
Does anyone know?

By the update apears this error. I dont understnand. Is it wrong to put 
text in the Content?
"[Line 29, Column 15, element content] This element must not have any 
text() data"

You can't access the content of the documents using the API.
What you can do is creating a text file and uploading it using 
docService.UploadDocument().
