Syntax

Function GetBufferPositionFromXCoordinate ( _
xCoordinate As Double, _
textOnly As Boolean _
) As Nullable(Of SnapshotPoint)
Nullable<SnapshotPoint> GetBufferPositionFromXCoordinate(
double xCoordinate,
bool textOnly

abstract GetBufferPositionFromXCoordinate :
xCoordinate:float *
textOnly:bool -> Nullable<SnapshotPoint>
function GetBufferPositionFromXCoordinate(
xCoordinate : double,
textOnly : boolean
) : Nullable<SnapshotPoint>
Parameters
- xCoordinate
Type: System.Double
The x-coordinate of the desired character.
- textOnly
Type: System.Boolean
If true, then this method will return nulla null reference (Nothing in Visual Basic) if xCoordinate is over an adornment.
Return Value
Type: System.Nullable<SnapshotPoint>
The text buffer-based point of the character at xCoordinate, or nulla null reference (Nothing in Visual Basic) if there is no character at that position.
Remarks
The rightmost edge of a character bound is considered to be contained in its following character. The rightmost edge of the last character's bounds do not map to any character. If textOnly is true and xCoordinate is over an adornment, then the text position associated with the adornment is returned.
