SetVCAN4Settings Method - neoVI API

This method writes configuration settings to a ValueCAN4-4 device.

int _stdcall icsneoSetVCAN4Settings(void * hObject, SVCAN4Settings *pSettings, int iNumBytes, int bSaveToEEPROM);

Parameters

hObject

[in] Specifies the driver object created by OpenNeoDevice.

pSettings

[in] The address of an allocated SVCAN4Settings structure.

iNumBytes

[in] This value is always the size, in bytes, of the SVCAN4Settings structure.

bSaveToEEPROM

[in] If set to 0, the settings changes will revert to the values stored in EEPROM when the ValueCAN3 is power-cycled. If set to 1, the values will overwrite the EEPROM settings and become persistent across power-cycles of the ValueCAN4-4.

Return Values

Returns 1 if successful, 0 if an error occurred. GetLastAPIError must be called to obtain the specific error. The errors that can be generated by this function are:

NEOVI_ERROR_DLL_NEOVI_NO_RESPONSE = 75

Remarks

Before using this function, the SVCAN4Settings structure must be initialized with the current neoVI settings using GetVCAN4Settings.

Examples

SVCAN4Settings VCANReadSettings;
int iNumberOfBytes;
int iResult;

//################################
//VCANReadSettings struct is read
//and changed as needed before
//Setting the new values
//################################

iNumberOfBytes=sizeof(VCANReadSettings );
iResult = icsneoSetVCAN4Settings(m_hObject, &VCANReadSettings , iNumberOfBytes, 1);
if(iResult == 0)
{
    MessageBox::Show("Problem Sending VCAN configuration");
    return;
}

SVCAN4Settings VCANReadSettings = new SVCAN4Settings();
int iNumberOfBytes;
int iResult;

//################################
//VCANReadSettings struct is read
//and changed as needed before
//Setting the new values
//################################

iNumberOfBytes = System.Runtime.InteropServices.Marshal.SizeOf(VCANReadSettings);
iResult = icsNeoDll.icsneoSetVCAN4Settings(m_hObject, ref VCANReadSettings , iNumberOfBytes, 1);

if(iResult == 0)
{
    MessageBox.Show("Problem Sending VCAN configuration");
    return;
}

Dim VCANReadSettings As SVCAN4Settings
Dim iNumberOfBytes As Integer
Dim iResult As Integer

'//################################
'//VCANReadSettings struct is read
'//and changed as needed before
'//Setting the new values
'//################################

iNumberOfBytes = System.Runtime.InteropServices.Marshal.SizeOf(VCANReadSettings)
iResult = icsneoSetVCAN4Settings(m_hObject, VCANReadSettings , iNumberOfBytes, 1)

If iResult = 0 Then
    MsgBox("Problem Sending VCAN configuration")
    Exit Sub
End If
