MakeFormTransparent Me, vbBlackCita de: Lupin en 23 Julio 2009, 23:10 PM
claro mi idea no es exactamente como dices BlackZeroX pero tu propuesta es interesante me podrias dar una idea que registros debo escrbir...
La verdad es que si widows llama a las funciones que necesite dentro de mi dll no las van a encontrar...pero sin embargo me da la impresion que las carga (parcialmente talvez o simplemente las abre) en memoria porque no la puedo borrar cuando la reemplazo
