Bonjour,

�tant un l�ger habitu� de delphi, la source de programmation qui fonctionne pour r�cup�rer une valeur sur mon port USB que j'ai pu trouv� est compil� sous Visual C++ et afin de l'utiliser j'essai de comprendre comment il fonctionne globalement.

J'ai pu rep�rer a quel moment la valeur est r�cup�rer et afficher dans une textbox, seulement mon probl�me est qu'il m'affiche ma valeur en ASCII et non comme je le souhaiterai en decimal.

Si je ne trompe pas la fonction qui r�cup�re ma donn�e est celle-ci

		private: System::Void serialPort1_DataReceived(System::Object^  sender, System::IO::Ports::SerialDataReceivedEventArgs^  e) 
		{
			//The ReadExisting() function will read all of the data that
			//  is currently available in the COM port buffer.  In this 
			//  example we are sending all of the available COM port data
			//  to the SetText() function.
			//
			//  NOTE: the <SerialPort>_DataReceived() function is launched
			//  in a seperate thread from the rest of the application.  A
			//  delegate function is required in order to properly access
			//  any managed objects inside of the other thread.  Since we
			//  will be writing to a textBox (a managed object) the delegate
			//  function is required.  Please see the SetText() function for 
			//  more information about delegate functions and how to use them.
			try
			{
				SetText(serialPort1->ReadExisting());
			}
			catch(...)
			{
			}
		}
Puis je l'affiche ici :

				//Invoke the new delegate sending the same text to the
				//  delegate that was passed into this function from the

			}
			else
			{
				//If this function was called from the same thread that 
				//  holds the required objects then just add the text.
 
				txtDataReceived1->AppendText(text); // laurent
				//txtDataReceived->AppendText(text); 
			}
		}
s'il vous plait d�tes moi comment ou avec quelle fonction je peux afficher ma valeur en d�cimal ?

Merci
