You mentioned in your instructions to catch / trap for the user clicking save, delete, edit button at the wrong time and didn't cover it is in the solution. I just went ahead and set the isEnabled for each of the buttons to prevent the user form clicking the wrong button in the first place...

I did this with a method setIconButtons(bool edit, bool save, bool delete) and then in each icon button click I told it which icon buttons to turn on / off…

Great lesson!

Thanks,

Scott

Hey theres actually an enumeration for Filemode called "Truncate" that will Completely wipe all data in the file without creating another.

Love the Series Marco

I made a mess of mine. I did everything up to the save point. When trying to save it I was using the technique from the Tombstoning lesson, it didnt work

Ahh, I've just finished the full thing and I did the delete function different, with fewer lines of code.

I called the isolated storage and deleted the file, then set the textbox to "".

3 lines of code is all it took

Also, to delete the file, couldn't you have just used -

private void delete_click(object sender, EventArgs e)
        {
            string fileName = "My_Note.txt";
            IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication();
            storage.DeleteFile(fileName);
            outputBox.Text = "";
            inputBox.Text = "";
        } // Delete
