GetVCAN4Settings Method - neoVI API

This method reads the configuration settings from a ValueCAN4-4 device.

int _stdcall icsneoGetVCAN4Settings(void * hObject, SVCAN4Settings *pSettings, int iNumBytes);

Parameters

hObject __ [in] Specifies the driver object created by OpenNeoDevice.

pSettings [out] Pointer to a SVCAN4Settings structure.

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

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

After getting the current settings, you may change the parameters defined in the SVCAN4Settings structure and write the settings back to the ValueCAN 4-4 using SetVCAN4Settings.

Examples

SVCAN4Settings VcanReadSettings;
int iNumberOfBytes;
int iResult;

//Get the settings
iNumberOfBytes=sizeof(VcanReadSettings );
iResult = icsneoGetVCAN4Settings(m_hObject, &VcanReadSettings , iNumberOfBytes);
if(iResult == 0)
{
    MessageBox::Show("Problem reading configuration");
    return;
}

//Declared at form level and previously open with a call to OpenNeoDevice
IntPtr m_hObject; //handle for device,
SVCAN4Settings VcanReadSettings = new SVCAN4Settings();
int iNumberOfBytes;
int iResult;

//Get the settings
iNumberOfBytes = System.Runtime.InteropServices.Marshal.SizeOf(VcanReadSettings);
iResult = icsNeoDll.icsneoGetVCAN4Settings(m_hObject,ref VcanReadSettings , iNumberOfBytes);
if (iResult == 0)
{
    MessageBox.Show("Problem reading configuration");
    return;
}

Private m_hObject As IntPtr '// Declared at form level and previously open with a call to OpenNeoDevice

Dim VcanReadSettings As SVCAN4Settings
Dim iNumberOfBytes As Integer
Dim iResult As Integer

'//Get the settings
iNumberOfBytes = System.Runtime.InteropServices.Marshal.SizeOf(VcanReadSettings)
iResult = icsneoGetVCAN4Settings(m_hObject, VcanReadSettings , iNumberOfBytes)
If iResult = 0 Then
    MsgBox("Problem reading configuration")
    Exit Sub
End If
