I'm trying to read the longitudinal acceleration from Fsuipc (3070), however this is a double float (FLOAT64). The problem I have is that the return value depicted in the string is a forever changing number (e.g. 34519859). This situation is described in the Dai Griffiths gauge tutorial, and suggests forcing the value to a UINT32 etc - though I'm not quite sure how to go about this? I have the following: case PANEL_SERVICE_PRE_UPDATE: FSUIPC_Read(0x3070, 8, &zacc, &dwResult); *pzac = zacc; FSUIPC_Process(&dwResult);Any help or suggestions would be great! Andy[/font size]

Was using DWORD instead of DOUBLE - sorry for the unnecessary post!Andy[/font size]
