cursor

I've executed some queries on my SQLite DB on Android. Main instruction used is this: Cursor cursor = myDB.rawQuery(select, null); Now I want the results of this query to be converted to a generic class I've created in the project. If you think I want an ORM system, you are right, but all I've found now are ORM systems that want to query the DB, save objects in the DB and manage the DB itself. Instead now I need a 'simple' ORM feature that can do exactly what the google.gson library does with JSON strings, it converts JSON strings to custom objects, and I want the same but for converting

In my opinion the MS Office Smooth Typing is a very innovating feature in the Office Suite, and I'd like to know if this feature is available for programmers in the .NET Framework, specifically in the C# language. If so, could you please post in your answer a link to the documentation and might also a usage example ? Thanks. I don't own Office, so I can't look at the feature, but I needed to fiddle around with the caret in RichTextBoxes a while ago and decided that it wasn't worth the effort. Basically you are on your own. No helper functions from .NET, but everything is handled by the backing

I am trying to get column value from a cursor, this column is generated at run time by calculations inside the query, I am getting a null value of this column, I am able to get a value of all other columns which exists in SQLite table. I execute the same query on SQLite editor, it also shows the value of generated column in result set. Why this giving null value when I am retrieving it from cursor?
