LotusScript/COM/OLE Classes
LotusScript® Classes Coding Guidelines
The following topics cover some general guidelines for writing LotusScript® code using Domino® objects:
Using OLE custom controls
You can embed OLE custom controls in Domino® Designer forms and write scripts for them just as you can for a native object. When a control is active (has focus), the menu is a combination of Domino Designer (File, Applet, and Window) and control items. The control menu items may include one for itself (for example, "Spreadsheet" for a spreadsheet control) and Help--the control help is substituted for Domino Designer help.

Examples: Using OLE custom controls

This example creates a new calendar control in the Body field of a new document, or accesses the existing control in an existing document, and sets the first day of the week from Sunday to Monday.

Sub Postopen(Source As Notesuidocument)
  Source.EditMode = True
  Call Source.GoToField("Body")
  If source.IsNewDoc Then
    Set Cal = Source.CreateObject _
    ("Calendar", _
    "MSCAL.Calendar.7")
  Else
    Set Cal = Source.GetObject _
    ("Calendar")
  End If
  Cal.FirstDay = 2
 End Sub

This example handles the Click event for a calendar control component inserted in the form through the UI. The script displays the date which the user clicks on in the calendar control.
```
Sub Click(Source As Calendar)
  Messagebox "You clicked on the following date: "_
  & Source.Month &"/" & Source.Day &"/"_
  & Source.Year
End Sub
```
