FilePermissions in CF?

[Daniel Barisch]

On executing

"Me.DataSet.WriteXml(New System.Xml.XmlTextWriter(strName,
System.Text.Encoding.UTF8), System.Data.XmlWriteMode.WriteSchema)"

(Me.DataSet is a property to a System.Data.DataSet)

I always get an IOException, if the file already exists. I guess there's a
proplem with file-permissions. But the Namespace System.Security.Permissions
is empty in CF?

Whats wrong with this code and how can I access the file-permissions?

Thanks, D.Barisch

Daniel,

It sounds like the file you're trying to write to is already in use if you only
get the IOException when the file previously exists. Does it work if you just
use Me.DataSet.WriteXml(strName)?

Thank you for your help!

That was the reason! I didn't close the filestream I've used to read the
DataSet.
