The OLE Scheduling Library exposes an object model for Microsoft Schedule Plus 7.0 that can be manipulated by the VBA language. This object model allows programmers to gain access to appointment information. This article provides a code sample of how to extract appointment information between two given dates from Schedule Plus.


  1. Start Visual Basic. If Visual Basic is already running, choose New Project from the File menu. Form1 is created by default.
  2. Place a Command button on Form1.
  3. Add the following code to the General Declarations section of Form1:
       Option Explicit
       Private Sub Command1_Click()
         GetAppointments "06/03/96", "08/03/96"
       End Sub
       Sub GetAppointments(sStartdate As String, sEndDate As String)
         Dim objSchdPlus As Object
         Dim gobjappt As Object
         Dim objappt As Object
         Dim objitem As Object
         Dim obatt As Object
         Screen.MousePointer = vbHourglass
         Set objSchdPlus = CreateObject("SchedulePlus.Application")
         Set gobjappt = objSchdPlus.ScheduleSelected
         Print objSchdPlus.UserName
         Set objappt = gobjappt.singleappointments
         Set objitem = objappt.Item()
         Print objappt.Rows
         While Not objappt.IsEndOfTable
           Set objitem = objappt.Item()
           If CDate(objitem.start) >= CDate(Format$(sStartdate, "dd/mm/yy") & _
             " 00:00:00") And CDate(objitem.end) <= CDate(Format$(sEndDate, _
             "dd/mm/yy") & " 23:59:59") Then
             Print "Starts " & objitem.start & "---" & "Ends " & objitem.end
             Print "Appointment := " & objitem.Text
           End If
         Screen.MousePointer = vbArrow
         MsgBox "Done"
       End Sub
  4. Press the F5 key to run the project. When you click on the button, the appointments that fall into the date range specified will be printed onto the form.
