Interface descriptionComments:The contents of the device list are only changed when a CAN interface board isadded or removed. To check whether the contents of the device list havechanged, without blocking the calling program, the value 0 can be specified inthe parameter dwMsTimeout when calling the program.4.2.1.6 vciFindDeviceByHwidThe function searches for a CAN interface board with a certain hardware ID. Thecomplete syntax of the function is:HRESULT vciFindDeviceByHwid (REFGUID rHardwareId,PVCIID pVciidDevice );Parameters:rHardwareId[in] Reference to the unique hardware ID of the CAN interface boardsearched for.pVciidDevice[out] Address of a variable type VCIID. If run successfully, the functionreturns the device ID of the found CAN interface board in this variable.Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function vciFormatError.Comments:The device ID returned by this function can be used to open the CAN interfaceboard with the function vciDeviceOpen.Each CAN interface board has a unique hardware ID, which also remains validafter a restart of the system.44Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
Interface description4.2.1.7 vciFindDeviceByClassThe function searches for a CAN interface board with a certain device class. Thecomplete syntax of the function is:HRESULT vciFindDeviceByHwid (REFGUID rDeviceClass,UINT32 dwInstNumber,PVCIID pVciidDevice );Parameters:rDeviceClass[in] Reference to the device class of the CAN interface board searched for.dwInstNumber[in] Instance number of the CAN interface board searched for. If more thanone CAN interface board of the same class is available, this value defines thenumber of the CAN interface board searched for in the device list. The value0 selects the first CAN interface board of the specified device class.pVciidDevice[out] Address of a variable type VCIID. If run successfully, the functionreturns the device ID of the found CAN interface board in this variable.Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function vciFormatError.Comments:The device ID returned by this function can be used to open the CAN interfaceboard with the function vciDeviceOpen.4.2.1.8 vciSelectDeviceDlgThe function displays a dialog window to select a CAN interface board from thecurrent device list on the screen. The complete syntax of the function is:HRESULT vciSelectDeviceDlg (HWND hwndParent,PVCIID pVciidDevice );Parameters:hwndParent[in] Handle of the higher order window. If the value ZERO is specified here,the dialog window has no higher order window.45Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
