My application uses Valentina as database which can create SQL dumps when the database is corrupted. I select a location with a SaveAsDialog and the data is written. Works fine even for the Sandbox.
Now there is a new version of creating a dump file called DumpEx which writes largish amounts of binary data into a second file next to the dump file. For the non-sandboxed version this is simple to solve. I have a standard name and do a
dim DataFile as FolderItem = DumpFolderitem.Parent.Child(kDumpDatafile)
This fails when the app is sandboxed because I don’t have write access to the second file.
What is the easiest solution to solve this? Show a second SaveAsDialog? Can I get write access to the parent folder? Can I simply write the files to the desktop? If I use the second SaveAsDialog I will need to show 2 file selection dialogs when loading the Dump file.
