\n\tThe Simplest Form
\n<\/h1>\n

\n\tThere are only three things required to launch a form from PowerShell:\n<\/p>\n

    \n
  1. \n\t\tYou must load the System.Windows.Forms assembly (if not already done);\n\t<\/li>\n
  2. \n\t\tYou must create a new object of type system.windows.forms.form; and,\n\t<\/li>\n
  3. \n\t\tYou must call the ShowDialog() method on your new object. Note—don’t try calling the Show() method, unless you want your script to hang.\n\t<\/li>\n<\/ol>\n

    \n\tFor example:\n<\/p>\n

    \n\tAdd-Type -AssemblyName System.Windows.Forms\n<\/p>\n

    \n\t$Form = New-Object system.Windows.Forms.Form\n<\/p>\n

    \n\t$Form.ShowDialog()\n<\/p>\n

    \n\t \n<\/p>\n

    \n\tDepending on your Windows shell environment, this is what your form might look like:\n<\/p>\n

    \n\t\"clip_image001\"<\/a>\n<\/p>\n

    \n\tOf course, that’s not terribly useful, so we’ll keep going.\n<\/p>\n

    \n\tAdding Some Text
    \n<\/h1>\n

    \n\tText will be helpful in adding some purpose to our form. There are a couple of pieces of text we’ll add.\n<\/p>\n

    \n\tFirst, let’s add a window title for the form by setting the form’s Text property. This will show up in the top of the form and will also serve as the window title as shown in the task bar.\n<\/p>\n

    \n\tThen we’ll add some text in the main window by adding a label control. In order to add a label, we need to create a new Label object, set the relevant properties and add it to the Controls collection of the form. For now, we’ll set only two properties—Text and AutoSize. Enabling AutoSize will ensure that our label is large enough to display all our text.\n<\/p>\n

    \n\tAdd-Type -AssemblyName System.Windows.Forms\n<\/p>\n

    \n\t$Form = New-Object system.Windows.Forms.Form\n<\/p>\n

    \n\t$Form.Text = "Sample Form"\n<\/p>\n

    \n\t$Label = New-Object System.Windows.Forms.Label\n<\/p>\n

    \n\t$Label.Text = "This form is very simple."\n<\/p>\n

    \n\t$Label.AutoSize = $True\n<\/p>\n

    \n\t$Form.Controls.Add($Label)\n<\/p>\n

    \n\t$Form.ShowDialog()\n<\/p>\n

    \n\t\"clip_image002\"<\/a>\n<\/p>\n

    \n\t \n<\/p>\n

    \n\tNote – Most forms will contain at least several controls. Usually there would be at least one button. We’ll add more controls later in this series, but for now we’ll just stick with a single label.\n<\/p>\n

    \n\tWe might want to change the font used by the form. In order to change the font, we need to create a new font object with the appropriate properties and assign the new font object to the form’s Font property.\n<\/p>\n

    \n\tAdd-Type -AssemblyName System.Windows.Forms\n<\/p>\n

    \n\t$Form = New-Object system.Windows.Forms.Form\n<\/p>\n

    \n\t$Form.Text = "Sample Form"\n<\/p>\n

    \n\t$Font = New-Object System.Drawing.Font("Times New Roman",18,[System.Drawing.FontStyle]::Italic)\n<\/p>\n

    \n\t# Font styles are: Regular, Bold, Italic, Underline, Strikeout\n<\/p>\n

    \n\t$Form.Font = $Font\n<\/p>\n

    \n\t$Label = New-Object System.Windows.Forms.Label\n<\/p>\n

    \n\t$Label.Text = "This form is very simple."\n<\/p>\n

    \n\t$Label.AutoSize = $True\n<\/p>\n

    \n\t$Form.Controls.Add($Label)\n<\/p>\n

    \n\t$Form.ShowDialog()\n<\/p>\n

    \n\t\"clip_image003\"<\/a>\n<\/p>\n

    \n\t \n<\/p>\n

    \n\tNow we have a bit of a problem because the text is too large to fit on the form in its default size. There are a few different ways we could address this:\n<\/p>\n
