cursor

问题 From what I saw, in Firefox and Chrome, the color of the text cursor in an input field changes to the value of the "color" css property. However in IE it has no effect whatsoever. Is there any way to achieve this effect in IE? 回答1: The color of the text cursor in an input on IE is always the inverse of the background color. So you can't on IE. This is also unspecced by W3C so don't expect support to be anywhere, if there is, then it's merely an artifact :-) Edit: 9-years later and we now have

问题 I have the following code, the first cursor object works fine, but when i do another query and assign it to the flightCursor, it gives the error. Cursor cursor = database.query( CityAndAirportsTable.notificationsTable, new String[] { CityAndAirportsTable.notifyFlightId }, null, null, null, null, "Id DESC" ); cursor.moveToFirst(); while( !cursor.isAfterLast() ){ String id = String.valueOf( cursor.getInt( 0 ) ); Cursor flightCursor = database.query( CityAndAirportsTable.flightTable, new String[

问题 I'm creating an ExpandableListView with data from a database. For that, I'm using a CursorTreeAdapter and I populate it with a Cursor object which contains the data I retrieve from database. I thought that, by default Android would consider the groups with no child "not expandable" . However it still shows the expand icon on the row, and when I click it, it does nothing. I don't want it to show this icon. I want only the groups that has childs to show the expand icon, which is not happening.

问题 There is a JTable in my application with resizable header columns. Normally when I move the cursor over table header for resizing, the cursor icon changes to resize arrow, like <-->.

Sometimes if I move the cursor over

问题 I am trying to call a stored procedure between python and an oracle db. The problem I am having is passing a cursor out-parameter.

问题 I am using a while loop to iterate through a cursor and then outputing the longitude and latitude values of every point within the database. For some reason it is not returning the last (or first depending on if I use Cursor.MoveToLast) set of longitude and latitude values in the cursor. Here is my code: public void loadTrack() { SQLiteDatabase db1 = waypoints.getWritableDatabase(); Cursor trackCursor = db1.query(TABLE_NAME, FROM, "trackidfk=1", null, null, null,ORDER_BY); trackCursor
