Microsoft® Visual Basic® Scripting Edition HelpContext Property | Language Reference Version 2

See Also Applies to

##### Description

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

##### Syntax

> object.HelpContext [= contextID]

> The HelpContext property syntax has these parts:

> Part | Description
> 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
