Microsoft® Office XP Developer Help contains numerous code samples that you can use to experiment with the concepts covered. Unless otherwise noted, the code is compatible with Microsoft® Visual Basic® for Applications (VBA) 6.0 as it is implemented in Visual Basic 6.0, Microsoft® Access, Microsoft® Excel, Microsoft® FrontPage®, Microsoft® Outlook®, Microsoft® PowerPoint®, Microsoft® Word, and other applications that host VBA 6.0. Additional code samples are written in Visual Basic Scripting Edition (VBScript), Microsoft® JScript®, HTML, and DHTML.

Help uses the following conventions in VBA sample code:

  • Keywords appear with an initial letter capitalized; concatenated words might contain other capital letters. Variables appear in mixed case, constants in uppercase.

    Dim objDatabase As Object
   Const PROP_NOT_FOUND_ERROR = 3270

   Set objDatabase = CurrentDb

  • In full procedures, all variables are declared locally or are listed with an initialization procedure that declares public variables. All code has been tested with the VBA Option Explicit statement to make sure there are no undeclared variables.

  • An apostrophe (') introduces a comment:

    ' This is a comment.
Dim intNew As Integer  ' This is also a comment.

  • Control-flow blocks and statements in Sub, Function, and Property procedures are indented:

    Sub MyCode ()
   Dim intX As Integer
   Dim intP As Integer
   Dim intQ As Integer

   If intX > 0 Then
      intP = intQ
   End If
End Sub

  • Naming conventions are used to make it easier to identify objects and variables in the code samples. For more information about naming conventions, see Writing Solid Code.

Help also uses the following convention in HTML script samples:

  • The HTML and DHTML naming conventions use a lowercase or lowercase and uppercase concatenated style for object, variable, method, event, function, and property names. For example, the name of the document object is lowercase, whereas the name of the srcElement property is a concatenated lowercase and uppercase combination.
