As far as I can remember wxWidgets itself shows an error message through wxLogError if the write operation fails. Maybe not the ideal solution. > So how can I manage this case? You should verify that the file of which you path the name to method SaveAsFile is indeed writable, before calling SaveAsFile. In my own applications I sometimes let method SaveAsFile write to a temporary file and rename the file thereafter. If renaming fails I issue an appropriate error message and let the user choose what to do - either retry (if the file was locked by another application) or choose a new file name.
