GetVCANRFSettings Method - neoVI API

This method reads the configuration settings from a ValueCAN RF device.

C/C++ Declare

int _stdcall icsneoGetVCANRFSettings(void * hObject, SVCANRFSettings *pSettings, int iNumBytes);

Visual Basic .NET Declare

Public Declare Function icsneoGetVCANRFSettings Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByRef pSettings As SVCANRFSettings, ByVal iNumBytes As Int32) As Int32e

C# Declare

[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoGetVCANRFSettings(IntPtr hObject, ref SVCANRFSettings pSettings, Int32 iNumBytes);

Parameters

hObject

[in] Specifies the driver object created by OpenNeoDevice.

pSettings

[out] Pointer to a SVCANRFSettings structure.

iNumBytes

[in] This value is always the size, in bytes, of the SVCANRFSettings 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 SVCANRFSettings structure and write the settings back to the ValueCAN RF using SetVCANRFSettings.

Examples

C/C++ Example

SVCANRFSettings VcanReadSettings;
int iNumberOfBytes;
int iResult;

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

C# Example

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

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

Visual Basic .NET Example

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

Dim VcanReadSettings As SVCANRFSettings
Dim iNumberOfBytes As Integer
Dim iResult As Integer

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