SQL Server Tips by Gama and Naughter Consulting


Testing the Code (COM Support)

To test the code as a late bound COM object, a simple Windows JScript script is provided called “ServerReachable.js”. This is located in a “JScript” directory underneath the XP code directory. It contains the following code:

var objServerReachable = new ActiveXObject("XP_SERVERREACHABLE.ServerReachable");

var ServerToPing = "";
var Reachable = objServerReachable.ServerReachable(ServerToPing);

WScript.Echo("Reachable: " + Reachable);

objServerReachable = null;

To test the COM support from an early bound client, a simple Visual Basic 6 client is supplied in a “VB6” directory. To connect to the COM DLL, a reference for the “XP_SERVERREACHABLE 1.0 Type Library” is added to the project by using the “Project - References” menu item in Visual Basic. The project contains a very simple form with 2 text boxes and a button. The following code is run when the “Ping” button is clicked:

Dim objServerReachable As New XP_SERVERREACHABLELib.ServerReachable
MousePointer = vbHourglass
Text2.Text = objServerReachable.ServerReachable(Text1.Text)
MousePointer = vbDefault
Set objServerReachable = Nothing
