The Scripting Guys recently posted <\/font>Weekend Scripter: Creating a GUI for a Windows PowerShell Script<\/font><\/a>, in which Ed Wilson builds a Windows form GUI application for a Windows PowerShell script. In today’s post, I’ll build the same GUI application but with the Windows Presentation Foundation PowerShell Kit (WPK).<\/p>\n

<\/font><\/font><\/p>\n

About WPK<\/font><\/span><\/h3>\n

WPK allows you to build rich user interfaces entirely with Window PowerShell scripts. WPK provides more than 600 cmdlets, which allow you to add WPF buttons, grids, list boxes, and more to Windows forms. <\/p>\n

<\/font><\/font><\/p>\n

James Brundage, author of WPK, says “WPK pays homage to Tcl\/Tk.” Tcl (pronounced “Tickle”) is a programming language created in 1990 by John Ousterhout when he was a professor at the University of California, Berkeley.<\/p>\n

<\/font><\/font><\/p>\n

Hello World in WPK<\/font><\/span><\/h3>\n

You need to download and install the <\/font>Microsoft PowerShell Power Pack <\/font><\/a>to try out these examples.<\/p>\n

<\/font><\/font><\/p>\n

WPK provides access to the presentation layer in WPF, surfacing controls in the standard Verb-Noun form. This example shows how you can add a label to a window and display, “Hello World.” In addition, each control has parameters. For the New-Window<\/b> cmdlet, we are using four parameters: Height<\/b>, Width<\/b>, Show<\/b>, and Content<\/b>. In the example, the Content<\/b> parameter is implied so that we can shorten the script by leaving it out. It would come after the Show<\/b> parameter.<\/font><\/font><\/p>\n


Import-Module WPK<\/p>\n

<\/font><\/font><\/b><\/p>\n

New-Window -Height 125 -Width 300 -Show {<\/p>\n

<\/span><\/p>\n

    <\/span>New-Label “Hello World” -FontSize 50<\/p>\n

<\/span><\/p>\n

}<\/p>\n

The Code<\/font><\/span><\/h3>\n

First, you need to <\/font>download WPK<\/font><\/a> from the MSDN Code Gallery. WPK lets you create rich user interfaces quick and easily from Windows PowerShell. Think HTA, but easy. <\/font><\/font><\/p>\n


Import-Module WPK<\/p>\n

<\/font><\/font><\/b><\/p>\n

New-Window -Title “Trip Cost” -WindowStartupLocation CenterScreen `<\/p>\n

<\/span><\/p>\n

  <\/span>-Width 300 -Height 200 -Show {<\/p>\n

      <\/span>$txtMiles          <\/span>= $Window | Get-ChildControl txtMiles <\/p>\n

<\/span><\/p>\n

      <\/span>$txtMilesPerGallon = $Window | Get-ChildControl txtMilesPerGallon <\/p>\n

<\/span><\/p>\n

      <\/span>$txtCostPerGallon  <\/span>= $Window | Get-ChildControl txtCostPerGallon <\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

      <\/span>$txtTotalCost.Text = `<\/p>\n

<\/span><\/p>\n

    <\/span><\/p>\n

<\/span><\/p>\n

  <\/span>New-\nTextBox -Name txtTotalCost `<\/p>\n

<\/span><\/p>\n

    <\/span>-Row 0 -Column 1 -Margin 3<\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

  <\/span><\/p>\n

<\/span><\/p>\n

  <\/span>New-TextBlock -Text “Miles Per Gallon” `<\/p>\n

<\/span><\/p>\n

    <\/span>-Row 2 -Column 0 -VerticalAlignment Center -Margin 3<\/p>\n

<\/span><\/p>\n

}<\/p>\n

<\/span><\/p>\n


The Code Explained<\/font><\/span><\/h2>\n<\/p>\n

WPK is a Windows PowerShell module. To use a module, you first need to import it using the Import-Module<\/b> <\/i>cmdlet. <\/p>\n

<\/font><\/font><\/span><\/p>\n

<\/p>\n

 <\/font><\/p>\n

<\/span><\/p>\n

The Trip Cost GUI uses these WPK cmdlets:<\/p>\n
