Defines an interaction used to display information or instructions to the user. For example, Plug in your network cable and then proceed. The interaction then waits for the user to respond before returning.
Some extension points can contain substitution strings (for example, %param%). Each substitution string in the extension point is replaced with the value of the same named parameter specified in this list.
An extension point that extends this interaction. Each extension is a child element of ExtensionPoint. You can specify one or more of the following extensions (but only one of each).
Extension
Description
Link
Creates a link to the specified URL. The link is placed at the bottom of the interaction window. You must use this extension point in conjunction with the LinkText extension point. The URL can contain substitution strings (for example, %param%) that are specified in the ContextParameters element. The URL must begin with http, https, or mshelp.
LinkText
The text to use for a link. The contents of the LinkText element is the resource identifier of the localized string. You must use this extension point in conjunction with the Link extension point. The link text can contain substitution strings (for example, %param%) that are specified in the ContextParameters element.
LinkFlushWithText
By default, the link is displayed at the bottom of the wizard page. Use this element to align the link flush with the description text. This element is valid only if the Link element is specified. This extension's usage is LinkFlushWithText/.
NoCache
By default, the answer to an interaction is cached. When running in MSDT, if the interaction is called more than one time, the interaction is shown the first time and the cached answer is used thereafter (without displaying the interaction). Use this extension point to force the interaction to display on subsequent requests and to not get the answer from the cache. This extension's usage is NoCache/.
NoUI
Suppresses the interaction. Gets the responses to the interaction from the answer file rather than from the user. For details on using an answer file, see the [Get-TroubleshootingPack](get-troubleshootingpack-cmdlet.md) and [Invoke-TroubleshootingPack](invoke-troubleshootingpack-cmdlet.md) cmdlets. This extension's usage is NoUI/.
RTFDescription
A rich text format string that replaces the Description element of [DisplayInformation](package-displayinformation-complextype.md). If the client does not support rich text, the description string is used. The RTF string can contain substitution strings (for example, %param%) that are specified in the ContextParameters element. The RTFDescription element can contain an RTF string or a localized resource string (for example, "@diag.dll,-123" or "@diag.dll,RESOURCE.RTF").
