WEBCAM EN WINDOWS 64 BITS

[karinha]

Señores, porque traba el programa?

Alguno de ustedes tien una versón que funcione en windows de 64 bits?

Gracias, saludos.

Karinha,
El siguiente codigo (desde un directorio llamado C:\_CK_NEW\), basado en la clase WebCam desarrollada por Cesar E. Lozada, me funciona sin problemas en Windows 8.1 - 64 Bits.

#include "Fivewin.ch"
#DEFINE FALSE  .F.
#DEFINE TRUE   .T.

Static _oWebcam_ := nil, DllWebCam
