How can i lock a form in position on the desktop? - winforms

Question

I'm trying to make a form in PowerShell that gets locked to a fixed position on the desktop.
Because whenever I press the "Show Desktop" button on the bottom right corner on Win 8.1, the form disappears until I open a different window and close it.
I just want it there like it's a widget, here's a part of the code i'm using:
Add-Type -AssemblyName System.Windows.Forms
Add-Type -Assembly System.Drawing
$Image = [System.Drawing.Image]::Fromfile("Panel.png")
$Form = New-Object system.Windows.Forms.Form
$Form.BackgroundImage = $Image
$Form.BackgroundImageLayout = "None"
$Form.Text = "Reboot Server"
$Form.Width = 517
$Form.Height = 134
$Form.ControlBox = $False
$Form.StartPosition = 'Manual'
$Form.Location = "1390, 300"
$Form.FormBorderStyle = 'None'
$Form.BackColor = "#000000"
$Form.MaximizeBox = $False
$Form.MinimizeBox = $False
$Form.Icon = "icon.ico"
$Form.Image = [System.Drawing.Image]::Fromfile("Panel.png")
$Form.ShowInTaskbar = $False
$Font = New-Object System.Drawing.Font("Tahoma",10, [System.Drawing.FontStyle]::Bold)
$Form.Font = $Font
$Label = New-Object System.Windows.Forms.Label
$Label.Text = ""
$Label.AutoSize = $True
$Form.Controls.Add($Label)
' Button 1 - Reboot Server'
$Button1 = new-object System.Windows.Forms.Button
$Button1.Location = new-object System.Drawing.Size(234,51)
$Button1.Size = new-object System.Drawing.Size(77,55)
$Button1.AutoSize = $True
$Button1.Add_Click({start-process "Reboot.lnk"})
$Button1.FlatStyle = [System.Windows.Forms.FlatStyle]::Flat
$Button1.FlatAppearance.BorderSize=0
$Button1.BackColor = "Transparent"
$Button1.ForeColor = "Transparent"
$Button1.FlatAppearance.MouseDownBackColor = "Transparent"
$Button1.FlatAppearance.MouseOverBackColor = "Transparent"
$Button1.FlatAppearance.BorderColor = "#252525"
$Form.Controls.Add($Button1)
'----------------------------------------
$Form.ShowDialog() | Out-Null
Exit 0

For gadget style positions try to use a little snippet that I have made:
$Poistion = 'RightBottom'
$Coordinates = switch ($Poistion)
{
'LeftTop' { 0, 0 }
'LeftBottom' { 0, $([System.Windows.Forms.Screen]::PrimaryScreen.WorkingArea.Bottom - $Form.Height) }
'RightTop' { $([System.Windows.Forms.Screen]::PrimaryScreen.WorkingArea.Width - $Form.Width), 0 }
'RightBottom' { $([System.Windows.Forms.Screen]::PrimaryScreen.WorkingArea.Width - $Form.Width), $([System.Windows.Forms.Screen]::PrimaryScreen.WorkingArea.Bottom - $Form.Height) }
}
$Form.Location = New-Object System.Drawing.Point($Coordinates)
To keep your form up at the time when you activate "Show Desktop" set TopMost property to $True and MinimizeBox property to $False. Like so:
$Form.TopMost = $True
$Form.MinimizeBox = $False
When you click on Show Desktop or use its hotkey (Win+D) windows tries to send Minimize All command to running applications. After minimizing all the windows that can be minimized, it then takes the desktop and "raises" it to the top of the window stack so that no other windows cover it.
You could also try to use sizing events. Like so:
$Form_Resize={
$Form.WindowState = 'Normal'
}
$Form.add_Resize($Form_Resize)
