HelpContext Property 

Sets or returns a context ID for a topic in a Help File.

object.HelpContext [= contextID]

Arguments

• object
  Required. Always the Err object.

• contextID
  Optional. A valid identifier for a Help topic within the Help file.

Remarks

If a Help file is specified in HelpFile, the HelpContext property is used to automatically display the Help topic identified. If both HelpFile and HelpContext are empty, the value of the Number property is checked. If it corresponds to a VBScript run-time error value, then the VBScript Help context ID for the error is used. If the Number property doesn't correspond to a VBScript error, the contents screen for the VBScript Help file is displayed.

The following example illustrates use of the HelpContext property:

On Error Resume Next

Dim Msg

Err.Clear

Err.Raise 6   ' Generate "Overflow" error.

Err.Helpfile = "yourHelp.hlp"

Err.HelpContext = yourContextID

If Err.Number <> 0 Then

   Msg = "Press F1 or Help to see " & Err.Helpfile & " topic for" & _

   " the following HelpContext: " & Err.HelpContext

   MsgBox Msg, , "error: " & Err.Description, Err.Helpfile, Err.HelpContext

End If
