Using the WTP Cmdlets

  • Article

WTP provides the following cmdlets that you use in your scripts to communicate with WTP:

Using Update-DiagRootcause

To let WTP know the detection status of a root cause, the troubleshooter and verifier scripts use the Update-DiagRootcause cmdlet. If a root cause ID in the troubleshooting manifest is DetectPopupBlocker, the following example shows how to call Update-DiagRootcause from a verifier script.

#root cause Detected
Update-DiagRootcause -Id DetectPopupBlocker -Detected $true

Using Write-DiagProgress

To provide feedback to the user that the troubleshooting pack is making progress, use the Write-DiagProgress cmdlet. You should provide progress information whenever an action takes a long time to complete (more than one second). The following example shows how to use the Write-DiagProgress cmdlet to provide progress information to the user.

#Write a progress message to the user.
Write-DiagProgress -Activity "Checking Pop-up Blocker..."

Using Get-DiagInput

To get information from the user or to ask the user to perform a task, use the Get-DiagInput cmdlet. The interaction that you use must be defined in the troubleshooting manifest. For more details on using interactions, see Interacting with the User. If an interaction ID in the troubleshooting manifest is IT_Notification, the following example shows how to call Get-DiagInput.

#Lets the user select a color from a list of colors.
$color = Get-DiagInput -Id "ColorSelection"

Using Update-DiagReport

To add additional information to the results report that WTP creates, call the Update-DiagReport cmdlet. You can use the cmdlet to include the information directly in the report or you can include a link to a file that contains the additional information. For more details on providing custom reporting, see Reporting. The following example shows how to use Update-DiagReport to include IE popup settings with the details of the root cause in the report.

#Shows how to log the Internet Explorer Popup Settings to the Results Report in the troubleshooting phase.
$PopupMgr = Get-ItemProperty "Registry::HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\New Windows" "PopupMgr"
$PopupMgr | ConvertTo-Xml | Update-DiagReport -Id PopupMgr -RootcauseId DetectPopupBlocker -Name "Popup setting"-Description "Registry setting for Popup Blocker."
