问题 EDIT: changed the title to fit the code below. I'm trying to retrieve a list of acceptable values from an Oracle table, then performing a SELECT against another while comparing some fields against said list.

DECLARE TYPE gcur IS REF CURSOR; TYPE list_record IS TABLE OF my_table.my_field%TYPE; c_GENERIC gcur; c_LIST list_record; BEGIN OPEN c_GENERIC FOR SELECT my_field FROM my_table WHERE some_field = some_value; FETCH c

问题 This question is very similar to many other questions on StackOverflow, but I think it merits its own post due to a difference in approach compared to other questions here. I have a custom adapter that extends CursorAdapter . I'm updating the data and calling notifyChange on the appropriate URI in order to refresh the cursor. In debugging, I can see that this is working properly. Unfortunately, my list views are not being recreated. The reason that I need them to be recreated is because of my

问题 I have a System.Windows.Forms.Cursor with me and wanted to assign it to a WPF's image.Cursor property which happens to be of System.Windows.Input.Cursor type.

问题 Is there a simple way to use pygame to switch to an OS-defined cursor? For example, switching to the windows loading circle or apple beach-ball when loading, or changing to arrows when hovering over a draggable object? Pygame provides the cursor module for loading a bitmap to replace the cursor, but I'd like to defer to the OS-defined cursors instead. 来源： https://stackoverflow.com/questions/39839550/pygame-change-cursor-to-os-cursor

问题 I'm getting the error Couldn't read row 0, col 9 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
