itemStruct->TaxCategoryId = 9988; itemStruct->UnitPrice = 5.49; itemStruct->ItemDesc = (char*)CoTaskMemAlloc(255); strcpy_s(itemStruct->ItemDesc, 255, "item description"); return true; } The function expects a pointer to the structure, using it to populate the individual fields. We use CoTaskMemAlloc to allocate string memory so the PInvoke marshaler can automatically marshal and deallocate the string. To call this function using a C# class instance rather than a struct, we need to first implement the class: [StructLayout(LayoutKind.Sequential)] public class ManagedItem { private int m_ItemId; private string m_ItemDesc; private long m_CategoryCode; private double m_UnitPrice; private int m_TaxCategoryId; public ManagedItem() { m_ItemDesc = String.Empty; } public int ItemId { get{return m_ItemId;} set{m_ItemId = value;} } public string ItemDesc { get{return m_ItemDesc;} set{m_ItemDesc = value;} } public long CategoryCode { get{return m_CategoryCode;} set{m_CategoryCode = value;} } public double UnitPrice { get{return m_UnitPrice;} set{m_UnitPrice = value;} } public int TaxCategoryId {

get{return m_TaxCategoryId;} set{m_TaxCategoryId = value;} } } We define the individual fields using the same sequence and data types as expected by the unmanaged structure. LayoutKind.Sequential has been specified for the StructLayout attribute to tell the marshaler that the member variables of the class are already in the expected sequence. The presence of the StructLayout attribute informs the marshaler that this is a formatted class. We declare the actual variables as private and dress up the class with public accessor properties for each variable. Since this is a full-fledged class, we could have added any number of public or private methods without affecting our ability to pass the class to unmanaged code as a structure. All member variables are marshaled to unmanaged code, even if they are declared as private. Unlike serialization, marshaling does not require public access to the variables. The presence or absence of an accessor property does not affect marshaling. To pass an instance of this class to the function, we need to declare the function, adding the In and Out attributes: [DllImport("FlatAPIStructLib.DLL")] public static extern bool LookupItemDetail( [In, Out] ManagedItem item); Finally, the C# code to make the function call looks like this: //pass a class object as an [In,Out] ManagedItem item = new ManagedItem(); item.ItemId = 111; //call the unmanaged function using [In,Out] bool result = LookupItemDetail(item); //show the results Console.WriteLine( "LookupItemDetail results: {0},{1},{2},{3},{4}", item.ItemId, item.ItemDesc, item.TaxCategoryId, item.CategoryCode, item.UnitPrice); The Visual Basic .NET version of this code looks like this: Imports System Imports System.Runtime.InteropServices Module StructureClassesTest <StructLayout(LayoutKind.Sequential)> _ Public Class ManagedItem Private m_ItemId As Integer Private m_ItemDesc As String = String.Empty

Plugging directly into the Arduino probably isn t very convenient, so a short extension cable consisting of a four-core strip of ribbon cable with a male header on one end and a female header on the other can be a handy thing to have on hand. To test out the touch screen, connect it to your Arduino, then load the previous example sketch in the Arduino IDE, compile it, and upload it to the Arduino. Then activate the serial monitor in the IDE and make sure it s set to 38400bps so you can see the values being reported by the Arduino as you touch different parts of the touch screen. Try moving your finger or a stylus around on the screen to see how one value changes if you move along one axis, and the other value changes with the other axis. If it seems like the touch screen isn t working, make sure you re using the correct side it can be hard to tell sometimes! The back has a feel like hard glass, while the front (sensitive) side is coated with a plastic film that will feel softer.
