En remplacement de Sendkeys

    Le problème avec SendKeys qui modifie l'état du NumLock ( SendKeys causing NumLock to turn off ) est bien connu sous Office et VB. Voici MySendkeys qui peut être utiliser, en remplavement.

Note: Généralement,  SendKeys n'est pas recommandé dans un environnement de production, car la séquence de clé est interprétée par la fenêtre actuellement active. De toutes évidence, celà peut créer des comportements imprévisible, à tout le moins qu'on peut dire, dans le cas où une autre application recevrait le focus lorsque votre code initie le SendKeys. Un cas extrême est d'envoyer un "Y" à une application qui attendait une confirmation pour reformatter votre disque principal. Donc, en définitive, éviter d'utilise SendKey.
