EditPoint2.LessThan, méthode (TextPoint)

Retourne une valeur indiquant si la valeur de la propriété AbsoluteCharOffset de l'objet EditPoint appelé est inférieure à celle de l'objet TextPoint donné.

Espace de noms :  EnvDTE80
Assembly :  EnvDTE80 (dans EnvDTE80.dll)

Syntaxe

'Déclaration
Function LessThan ( _
    Point As TextPoint _
) As Boolean
bool LessThan(
    TextPoint Point
)
bool LessThan(
    [InAttribute] TextPoint^ Point

function LessThan(

Paramètres

Valeur de retour

Type : System.Boolean
true si Point a une valeur de propriété AbsoluteCharOffset supérieure à la propriété AbsoluteCharOffset de l'objet du point d'appel ; sinon, false.

Notes

LessThan lève une exception ArgumentException si Point n'est pas dans le même document que l'objet du point d'appel.Avec l'objet VirtualPoint, LessThan compare les positions virtuelles si l'argument est un VirtualPoint.Sinon, il compare les positions « physiques ».
