Rightness is what you have been testing so far. That is, does the program behave correctly when you provide it with the right information In other words, does it do the right thing when it should It is a good idea to write a range of tests to cover the expected range of possibilities. Here you have just a couple: 25 C converts to 77 F, and 98.6 F converts to 37 C. Some other values you might like to add include 0 C converts to 32 F, 0 F converts to 17.78 C, -40 C converts to 40 F, and so on. In practice this is a simple linear calculation, so beyond a couple of examples you don t need to keep testing for correct behavior.

Following these steps produces an object that follows the asynchronous design pattern. There are two choices in how to interact with the object in an asynchronous way. One involves passing a callback to the Begin<action> method that is invoked when execution completes. The alternative is to call End<action>. Calling it causes execution on that thread to block until the asynchronous execution completes. This allows the caller to start processing, continue executing some other task, and then call End<action> to wait for the asynchronous operation. The examples in this section have been presented in Visual Basic .NET. The C# version of the examples are available from the publisher s web site.

'' setup initial points ReDim dblVertices(11) dblVertices(0) = 0#: dblVertices(1) = 0# dblVertices(2) = 10#: dblVertices(3) = 0# dblVertices(4) = 10#: dblVertices(5) = 10# dblVertices(6) = 5#: dblVertices(7) = 5# dblVertices(8) = 2#: dblVertices(9) = 2# dblVertices(10) = 0#: dblVertices(11) = 10# '' draw the entity If ThisDrawing.ActiveSpace = acModelSpace Then Set objEnt = ThisDrawing.ModelSpace.AddLightWeightPolyline(dblVertices) Else Set objEnt = ThisDrawing.PaperSpace.AddLightWeightPolyline(dblVertices) End If objEnt.Closed = True objEnt.Update End Sub To add vertices to an LWPolyline object one at a time instead of all at once, use the AddVertex method. The following example uses this method in a loop, adding vertices to a selected polyline until the user is satisfied. Try using it on the polyline you created in the previous example: Public Sub TestAddVertex() On Error Resume Next Dim objEnt As AcadLWPolyline Dim dblNew(0 To 1) As Double Dim lngLastVertex As Long Dim varPick As Variant Dim varWCS As Variant With ThisDrawing.Utility '' get entity from user .GetEntity objEnt, varPick, vbCr & "Pick a polyline <exit>: " '' exit if no pick If objEnt Is Nothing Then Exit Sub '' exit if not a lwpolyline If objEnt.ObjectName <> "AcDbPolyline" Then MsgBox "You did not pick a polyline" Exit Sub End If
