Entrust the function of the c # COM:
Public delegate void DelNewData (object NewData);
The public event DelNewData OnNewData;
Public void NewData (object NewData)
{
Try
{
If (OnNewData!=null)
{
OnNewData (NewData);
}
}
The catch (Exception ex)
{
System. Diagnostics. Debug. Print (ex. ToString ());
}
}
Call COM used in c + + program:
