A ver si me explico :
tengo 2 programas.exe, el exe1 y el exe2

En el exe1 tengo una coleccion y un timer que constantemente esta
comprobando si hay algun elemento en la coleccion
para tratarlo.

Lo que necesito es, desde el exe2 enviar un elemento a la coleccion del
exe1, no se si esto se puede hacer.

Por cierto el interval del timer del exe1 lo tengo = 1, necesito que se
traten las lineas muy rapido, pero
realmente no se si es correcto y deberia ponerlo por ejemplo a 100, es decir
no se si afecta al rendimiento
el tener el interval tan bajo.
un saludo y gracias.
