Salut, j'ai cherché ton problème, en fait tu as oublié de faire qqch :
Il faut que tu ailles sur ton Form1.cs[design] tu séléctionnes la fenetre et tu vas dans le panneau "Propriétés" et tu cliques sur Evenements (symbolisé par un éclair) tu vas tout en bas et tu ecris à côté de la case "Key Up" le nom de la fonction dans mon exemple j'ai pris comme nom "KeyUp_actions" ensuite tu fais Entrée, t'es directement envoyé sur la page de code et là tu mets :
private void KeyUp_actions(object sender, System.Windows.Forms.KeyEventArgs e)
{
if(e.KeyCode == Keys.ControlKey)
{
this.label1.Text = "Ca marche";
}
else
{
this.label1.Text = "Ca marche pas";
}
if(e.KeyCode == Keys.Delete)
{
this.label1.Text = "salut";
}
}
Sinon mieux vaut mettre un label plutôt qu'un textbox car le textbox envoie directement ton curseur dans sa barre et ca fait donc foirer la prise de commande...
Si t'as un pb, envoie moi un mail...

pour agir si on apuie sur la touche Down ou Up..
il m'indique une erreur d'acceé (can not access) dans:
*****this.textBox.OnKeyDown += new System.Windows.Forms.KeyEventArgs(this.textBoxChanged);*******
est ce que tu peut m'aider a resoudre encore ce probleme.

Je crois qu'il est préférable de faire un OnKey down non pas sur le textbox mais sur le panneau qui contient le textbox, la fenetre "Form"quoi...car sinon si tu selectionnes pas le textbox ca marche pas ...
et encore une fois le textbox c pas top, le label est mieux...
