I try to declare MPUSBAPI in VB 2005 express, but ive found this declaration did not work:
Public Const VID_PID_NORM = "vid_04d8&pid_000c"
Public Const VID_PID_BOOT = "vid_04d8&pid_000b"
Public Const END_POINT = "\MCHP_EP1"
Declare Ansi Function MPUSBOpen Lib "MPUSBAPI.DLL" Alias "_MPUSBOpen" (ByVal DeviceInstance As UInteger, ByVal VID_PID As String, ByVal EndPoint As String, ByVal Direction As UInteger, ByVal Reserved As UInteger) As UInteger
and then i call:
OutPipe = MPUSBOpen(0, VID_PID_NORM, END_POINT, 1, 0)
It does not work because OutPipe = 0xffffffff (INVALID_HANDLE_VALUE)
so i think my declaration was wrong. I successully call MPUSBGetDeviceCount
It return 1 or 0 when i plug or unplug the board.
Sorry if i post this at wrong thread. |

Yeah, at last i've solved the problem. A bit stupid i am with VB.NET. But with VB6 the compiled DLL of microchip does not work. So i have modified it a liitle.
And now everything ok. I would like to include my code in your arctile, because i've found many guys had the same problem with me.
Thanks again. |
