我有一个power-shell表单提示用户是否要推迟关闭时间(关闭时间由另一个ps脚本作为参数在初始脚本中计算)。
我想在30分钟不活动后关闭表格,我该怎么办呢?
Powershell代码(表格):
#creating the form object
$form = New-Object System.Windows.Forms.Form
#setting the from title
$form.Text = "System warning"
#setting the form dimesnions and positions
$form.Size = New-Object System.Drawing.Size(300,250)
$form.StartPosition = "CenterScreen"
#claculate time before shut down:
$StartDate=(GET-DATE)
#this ill have to be replaced by a parameter which indicates the shut down date
$EndDate = $EndDate | Get-Date
$timeDifference = NEW-TIMESPAN –Start $StartDate –End $EndDate
$secondsTilShutdown = $timeDifference.TotalSeconds
#time remaining message
$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10,20)
$label.Size = New-Object System.Drawing.Size(280,40)
$label.Text = "This computer is scheduled to shutdown at " + $EndDate
$form.Controls.Add($label)
#second message
$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10,70)
$label.Size = New-Object System.Drawing.Size(280,20)
$label.Text = "Postpone the shutdown by : "
$form.Controls.Add($label)
#setting up the drop down box (time in minutes)
$TimePeriods = 60, 120, 180, 240
$DropDown = new-object System.Windows.Forms.ComboBox
$DropDown.Location = new-object System.Drawing.Size(10,90)
$DropDown.Size = new-object System.Drawing.Size(130,30)
ForEach ($time in $TimePeriods) {
[void] $DropDown.Items.Add([string]($time/60) + " hours")
}
#1 hour is the default
$DropDown.SelectedItem = $DropDown.Items[0]
$Form.Controls.Add($DropDown)
#creating the postpone button
$OKButton = New-Object System.Windows.Forms.Button
#position of the button on the form
$OKButton.Location = New-Object System.Drawing.Point(25,130)
#size of the button
$OKButton.Size = New-Object System.Drawing.Size(100,50)
#text of the button
$OKButton.Text = "Postpone"
#the value that the from dialog will return if we click on ok
$OKButton.DialogResult = [System.Windows.Forms.DialogResult]::OK
#assigns a key down on the enter key to the button
$form.AcceptButton = $OKButton
#adds the button to the form
$form.Controls.Add($OKButton)
#creating the ignore button
$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Point(175,130)
$CancelButton.Size = New-Object System.Drawing.Size(100,50)
$CancelButton.Text = "Continue with scheduled shutdown"
$CancelButton.DialogResult = [System.Windows.Forms.DialogResult]::Cancel
$form.CancelButton = $CancelButton
$form.Controls.Add($CancelButton)
$textBox = New-Object System.Windows.Forms.TextBox
$textBox.Location = New-Object System.Drawing.Point(10,40)
$textBox.Size = New-Object System.Drawing.Size(260,20)
$form.Controls.Add($textBox)
$form.Topmost = $True
$form.Add_Shown({$textBox.Select()})
$result = $form.ShowDialog()
###processing form results :
#if the postpone button button was selected
if ($result -eq [System.Windows.Forms.DialogResult]::OK)
{
#logic
}
elseif($result -eq [System.Windows.Forms.DialogResult]::Cancel)
{
#we do not push back the shut down time
}

使用计时器,我给你一个关闭计时器的例子
Function ClearAndClose()
{
$Timer.Stop();
$Form.Close();
$Form.Dispose();
$Timer.Dispose();
$Label.Dispose();
$Button.Dispose();
$Script:CountDown=5
}
Function Button_Click()
{
ClearAndClose
}
Function Timer_Tick()
{
$Label.Text = "Your system will reboot in $Script:CountDown seconds"
--$Script:CountDown
if ($Script:CountDown -lt 0)
{
ClearAndClose
}
}

$Timer = New-Object System.Windows.Forms.Timer
$Timer.Interval = 1000
$Form.Controls.Add($Label)
$Form.Controls.Add($Button)
$Script:CountDown = 6
$Button.Add_Click({Button_Click})
$Timer.Add_Tick({ Timer_Tick})
$Timer.Start()
$Form.ShowDialog()
