android - Import/ export data from sqllite database -


my question more related programming approach should used import/ export data sqllite database.

i'm new android app development , developing simple notepad application in want give option user export & import notes to/from file.

i've done quite research on web , found there various way that:

  1. write data database file in csv format - using opencsv library
  2. write data database file in xml format
  3. take backup of sqllite db file , replace while importing - believe approach won't let me keep old notes , import notes backup db file?

i know approach better. if there else better above ones know it.

i'd 1, without using 3rd party libraries (it's easy import , export comma delimited file!!).
can use replace command, updates existing data , inserts new one, if row not existing.

or 2.
xml files bloated garbage tags... , it's more complicated parse them reading/writing simple text files (with or without header row).

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
