Developin custom Functoid in BizTalk

1) Fine, create a new project its type is class library and name it CustomFunctoid.
2) Add a reference of Microsoft.BizTalk.BaseFunctoids you can find it here :X:\Program Files\Microsoft BizTalk Server 2006\Developer Tools\Microsoft.BizTalk.BaseFunctoids.dll (where X the drive that holds the installation of BizTalk server 2006)
3) let you class implement from BaseFunctoidpublic class Percentage : BaseFunctoid
4) let the constructor override the basepublic Percentage(): base()
5) write the following line of code in the construction :
this.ID = 3003;
SetupResourceAssembl("CustomFunctoid.CustomFunctoidResource", System.Reflection.Assembly.GetExecutingAssembly());
SetName("PERCENTAGE_NAME");
SetTooltip("PERCENTAGE_TOOLTIP");
SetDescription("PERCENTAGE_DESCRIPTION");
SetBitmap("PERCENTAGE_BITMAP");
this.SetMinParams(2);
this.SetMaxParams(2);
SetExternalFunctionName(GetType().Assembly.FullName, "CustomFunctoid.Percentage", "CalculatePercentage");
this.Category = FunctoidCategory.Math;
AddInputConnectionType(ConnectionType.AllExceptRecord);
AddInputConnectionType(ConnectionType.AllExceptRecord);
this.OutputConnectionType = ConnectionType.AllExceptRecord;

6)Now create the function that will calculate the percentage which is :

public float CalculatePercentage(float x, float y)
{
float c = float.MinValue;
c = (x / y) * 100;
return c;
}

7) Create a Strong key , and Assign it to your class library


8) Build the Class Library and copy the DLL to : X:\Program Files\Microsoft BizTalk Server 2006\Developer Tools\Mapper Extensions (where X is the drive that holds the installation of BizTalk Server 2006)
9) Add this dll it to the GAC ( open the Visual Studio 2005 Command Prompt and type GACUTIL –i X:\CustomFunctoid.dll)


10) Add it to the ToolBox in Visual Studio 2005 (right click on the ToolBox, choose Add/Remove items, click the Functoids tab and browse to the Customfunctoid.dll file and make sure it’s checked.
