This method downloads a script to a connected neoVI device into a specified location.
int _stdcall icsneoScriptLoad(void * hObject, const unsigned char *bin, unsigned long len_bytes, int iLocation);
Public Declare Function icsneoScriptLoad Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByRef bin As Byte, ByVal Len_Bytes As UInt32, ByVal iLocation As Int32) As Int32
bin[in] An array of bytes that represent a compiled script. These bytes are contained in a header file called cmvspy.h.
This file is created by Vehicle Spy when a script is compiled. Please see Vehicle Spy documentation for details.
len_bytes
[in] Specifies the number of bytes represented by the bin parameter
iLocation
[in] Specifies the physical location to where the script will be loaded on the neoVI device. Valid values are as follows:
SCRIPT_LOCATION_FLASH_MEM = 0 (Valid only on a neoVI Fire or neoVI Red)SCRIPT_LOCATION_SDCARD = 1 (Valid only on a neoVI Fire or neoVI Red)SCRIPT_LOCATION_VCAN3_MEM = 4 (Valid only on a ValueCAN 3 device)
These values are defined in the icsnVC40.h file
Return Values

End Function
The script will be stored on the device in the specified location. If the location is SCRIPT_LOCATION_FLASH_MEM or SCRIPT_LOCATION_SDCARD the script will persist in the device in that location until cleared by . If the neoVI device is booted (plugged in to power) without being connected to a USB port the stored script will execute. The location SCRIPT_LOCATION_VCAN3_MEM applies only to the ValueCAN 3 device and the storage will be cleared when power is removed from the device.
