That said, notice that the Body tag is a special tag. Or, at least, moving it into places where functionality can be more cohesive. And, that's kind of the whole point of what I'm trying to accomplish with this ColdFusion custom tag DSL: abstracting away a lot of the cruft. We are liberated from our own fear, our presence automatically liberatesĪs you may notice, there's nothing in this content that points to "dark mode". Shine, we unconsciously give other people permission to do the same. Not just in some of us it is in everyone. We are all meant to shine as children do. There is nothing enlightened about shrinking so that other people won'tįeel insecure around you. Your playing small does not serve the world. Our deepest fear is not that we are inadequate. Trying to formulate ideas around dark mode.
Doing this causes the rendered email to contain two additional snippets of code in the HTML : In addition to wrapping the tag, you may also notice that I am setting theme.enableDarkModeSupport to true. Now, yesterday, I already added a tag to my DSL so, I think I can add support for dark by with thin layer above this tag,, that just sets the appropriate media query name/value pair: In modern browsers, you can progressively enhance your web application to add special styles for both light and dark theme user preferences using the following CSS bocks: View this code in my ColdFusion Custom Tag Emails project on GitHub. As such, I wanted to see if I could do the same thing for dark mode. Yesterday, I added two abstractions for max-width and min-width.
Dark mode, like other responsive design elements, can be controlled on the web using queries. Import 7.app.As I've been testing my ColdFusion custom tag DSL (Domain Specific Language) for HTML emails in Litmus, I noticed that they offer previews for email clients running in "Dark Mode". SQLiteDatabase db = this.getReadableDatabase() Ĭursor cursor = db.rawQuery(countQuery, null) String countQuery = "SELECT * FROM " + TABLE_CONTACTS Public class DatabaseHandler extends SQLiteOpenHelper )
Let's see the simple example of android sqlite database. Int update(String table, ContentValues values, String whereClause, String whereArgs)Ĭursor query(String table, String columns, String selection, String selectionArgs, String groupBy, String having, String orderBy) The third argument specifies the values to be stored. If second argument is null, android will store null values if values are empty. The table specifies the table name, nullColumnHack doesn't allow completely null values. Long insert(String table, String nullColumnHack, ContentValues values) There are many methods in SQLiteDatabase class. It contains methods to be performed on sqlite database such as create, update, delete, select etc. Public void onDowngrade(SQLiteDatabase db, int oldVersion, int newVersion)Ĭalled when database needs to be downgraded. Public abstract void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)Ĭalled when database needs to be upgraded.
Public abstract void onCreate(SQLiteDatabase db)Ĭalled only once when database is created for the first time. There are many methods in SQLiteOpenHelper class. SQLiteOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version, DatabaseErrorHandler errorHandler)Ĭreates an object for creating, opening and managing the database. SQLiteOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version)Ĭreates an object for creating, opening and managing the database. There are two constructors of SQLiteOpenHelper class. For performing any database operation, you have to provide the implementation of onCreate() and onUpgrade() methods of SQLiteOpenHelper class. The class is used for database creation and version management. SQLiteOpenHelper class provides the functionality to use the SQLite database. For displaying data on the spinner or listview, move to the next page. Here, we are going to see the example of sqlite to store and fetch the data. So, there is no need to perform any database setup or administration task. used to perform database operations on android devices such as storing, manipulating or retrieving persistent data from the database. SQLite is an open-source relational database i.e.
