Recorrer un pchar

[Status Quo]

He puesto un solo socket para envíar los paquetes y he puesto el record así:


type
Paquete = record
Tipo: Integer;
Tamano: Integer;
TamaTotal:Integer;
NomFich:String;
Buffer: array[0..1024] of Byte;
end;


No se si habrá algún problema con los strings pero el caso esque no me llega el nombre en el código de recepción...

Pongo todo el código con el que estoy trabajando para hacer las pruebas(luego lo pasaré al que estoy haciendo yo...)

No se lo que son los tipos NonBlocking yo utilizo de la paleta de componentes--> internet el componente clientsockect y serversocket...

Seoane, te pongo el código este de pruebas...Cuando lo terminte(por favor que sea pronto) te paso el programa total...(como tu me digas que te viene mejor...)


Este es el código que envía el fichero:

Perdonar, no se porqué se me ha ido toda la indentación...
