This is the latest installment in our video series on working with Azure cmdlets in background jobs. In this example we are executing the PowerShell script in a Windows GUI Application.<\/p>\n

Minor Sample Script Changes<\/h3>\n

As the sample script evolves to execute\u00a0the job from a Windows GUI application instead of the Console, depending on the script complexity more changes might be needed to interact with the GUI components.<\/p>\n

The sample script executes the Stop-AzureRMVM cmdlet using the -AsJob parameter which will capture more information about the cmdlet being sent as a job:<\/p>\n

:\r\n## - Run Azure cmdlet with AsJob parameter:\r\nStop-AzureRMVM -ResourceGroupName \"GlobalAzureBootCampResources\" `\r\n-Name $Name `\r\n-AsJob `\r\n-Force -Verbose;\r\n:<\/pre>\n
The date\/time format will display the processing information in the RichTextBox “$DisplayText<\/em>” object:<\/p>\n
:\r\n$t = Get-Date;\r\n$DisplayText.AppendText(\"`r`nBackground Process Started - $($JobName) - $(($t).ToString(\"MM\/dd\/yyyy - HH:mm:ss\"))\")\r\n:<\/pre>\n
Sample GUI Application<\/h3>\n
The sample GUI Application has two controls: Button, and RichTextBox.<\/p>\n
The Button executes the code that will send the jobs to the background, and the RichTextBox is the area that will display the result of the task submitted by the button.<\/p>\n
