Assigning an integer to an AnsiString is perfectly acceptable - in this case it
would generate an implicit call to the __fastcall AnsiString::AnsiString( int)
constructor, creating a temporary String variable, and then a call to
AnsiString& __fastcall AnsiString::operator=(const AnsiString&), to perform the
actual assignment.

The general rule is that the compiler will search first through the operator='s,
and then the constructors of the type on the left hand side of the assignment.

If it's like other controls, the edit box won't repaint it's contents until the
app enters a message processing cycle - so if you do a lot of updates which hog
cycles from the normal message processing, that's when you use repaint.

Hope this helps,
