SetVCAN412Settings Method - neoVI API

This method writes configuration settings to a ValueCAN4-1 and ValueCAN4-2 device.

int _stdcall icsneoSetVCAN412Settings(void * hObject, SVCAN412Settings *pSettings, int iNumBytes, int bSaveToEEPROM);

Public Declare Function icsneoSetVCAN412Settings Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByRef pSettings As SVCAN412Settings, ByVal iNumBytes As Int32, ByVal bSaveToEEPROM As Int32) As Int32

Parameters

hObject

[in] Specifies the driver object created by OpenNeoDevice.

pSettings

[in] The address of an allocated SVCAN412Settings structure.

iNumBytes

[in] This value is always the size, in bytes, of the SVCAN412Settings 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 ValueCAN4-1 and ValueCAN4-2.

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 SVCAN412Settings structure must be initialized with the current neoVI settings using GetVCAN412Settings.

Examples

SVCAN412Settings VCANReadSettings;
int iNumberOfBytes;
int iResult;

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

iNumberOfBytes=sizeof(VCANReadSettings );
iResult = icsneoSetVCAN412Settings(m_hObject, &VCANReadSettings , iNumberOfBytes, 1);
if(iResult == 0)
{
    MessageBox::Show("Problem Sending VCAN configuration");
    return;
}

SVCAN412Settings VCANReadSettings = new VCANReadSettings();
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.icsneoSetVCAN412Settings(m_hObject, ref VCANReadSettings , iNumberOfBytes, 1);

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

Dim VCANReadSettings As SVCAN412Settings
Dim iNumberOfBytes As Integer
Dim iResult As IntPtr

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

iNumberOfBytes = System.Runtime.InteropServices.Marshal.SizeOf(VCANReadSettings)
iResult = icsneoSetVCAN412Settings(m_hObject, VCANReadSettings , iNumberOfBytes, 1)

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