If the managed and unmanaged versions of the structure do not match, PInvoke won t necessarily tell you that the structures don t match Instead, PInvoke will inform you that no entry point using the parameters that you have defined (the incorrect structure) can be found If you have decorated individual fields in the structure with the MarshalAs attribute, the attribute settings should be reviewed along with the data types of the structure fields The MarshalAs attribute does affect the PInvoke view of the function signature, and an incorrect MarshalAs attribute may be the root cause of the problem For example, we might incorrectly define the structure used in the example code like this: [StructLayout(LayoutKindSequential)] struct ManagedAmbiguousStruct { public ushort ShortInteger; [MarshalAs(UnmanagedTypeLPStr)] public string AnsiString; [MarshalAs(UnmanagedTypeLPWStr)] public string WideString; [MarshalAs(UnmanagedTypeBool)] public bool Win32Boolean; [MarshalAs(UnmanagedType.

In practice, this means that you should take extreme care if you have to deal with mains voltages. We strongly encourage you to avoid them if possible, but if you must interact with mains, some precautions you must take include the following: Don t work on mains-based projects solo. Have someone around who knows where to turn off the power and provide first aid if things go wrong. Don t work on the hardware when tired. Wear insulated footwear, such as rubber sole shoes. Only touch the hardware with one hand at a time. This, combined with insulated shoes, lessens the chance of your heart being in the current path. Isolate (i.e., unplug) the hardware whenever possible. Only work on equipment live as a last resort. Assume equipment is live unless you are absolutely sure it isn t. Ensure any metalwork is securely earthed. Ensure any wiring carrying mains voltage is of a suitable gauge (thickness) and insulation rating. Ensure any mains connections are well insulated and, as far as possible, hard to touch accidentally. If you are at all unsure of any aspect, consult an expert. Mains voltages don t provide much in the way of second chances. Don t be discouraged. If you re just using regular low-voltage Arduino applications, it s pretty hard to hurt yourself!

Figure 3-11. Assigning a project to a client There are two main reasons that you d want to group projects by client or department. First, doing so allows you to create a filter that lists all cases for a certain client or all cases in a certain department that you care about. Second, user access can be granted on a client or departmental level. This means that it s possible to create FogBugz accounts for your clients such that they can only see their own cases. You can also partition departments so that users can only see cases in their own department. I ll cover these techniques next.

I1)] public bool CStyleBoolean; }; This incorrectly places the ShortInteger field at the beginning of the structure If we make this change and run the sample code again, an EntryPointNotFoundException will be thrown with this message: Unable to find an entry point named 'UseAmbiguousStruct' in DLL 'FlatAPIStructLibDLL After comparing the two versions of the structure and correcting any errors, the exception should be eliminated If the function uses __cdecl instead of __stdcall, we would receive a different result The entry point would be found and the call would occur However, since the managed and unmanaged structures do not agree, the unmanaged function would receive and act upon incorrect data..
