[system.reflection.assembly]::loadwithpartialname("system.windows.forms") | out-null [system.reflection.assembly]::loadwithpartialname("system.drawing") | out-null  set-location $psscriptroot  #call scripts installation $scriptshome = get-item '.\test\forps\*'  #define form # init form $form = new-object system.windows.forms.form $form.width = 1000 $form.height = 200 $form.text = "** installation in progress-please not close window**" $form.font = new-object system.drawing.font("times new roman" ,12, [system.drawing.fontstyle]::regular) $form.minimizebox = $false $form.maximizebox = $false $form.windowstate = "normal" $form.startposition = "centerscreen" $form.opacity = .8 $form.backcolor = "gray"  #define icon form $icon = new-object system.drawing.graphics (".\icon.jpg") $form.icon = $icon  # init progressbar $progressbar = new-object system.windows.forms.progressbar $progressbar.maximum = $scriptshome.count $progressbar.minimum = 0 $progressbar.location = new-object system.drawing.size(10,70) $progressbar.size = new-object system.drawing.size(967,10) $form.controls.add($progressbar) $form.controls.add($messages)  #running script name $label = new-object system.windows.forms.label $label.autosize = $true $label.location = new-object system.drawing.point(10,50)  $form.controls.add($label)  #define array messages #array $messages = @("preparing install patch set..preparing stop related processes",                 "upgrading application",                 "copying missing folder",                 "applying patch",                 "starting stopped services",                 "checkcing healthyness of system after installation may take half hour...",                 "rebooting server"                 ) $messages = new-object system.windows.forms.label $messages.autosize = $true $messages.location = new-object system.drawing.point(10,50) $form.controls.add($messages)   # add_shown action     $shownformaction = {     $form.activate()      foreach ($script in $scriptshome) {         $progressbar.increment(1)         #$messages.text = $messages[$messages]         $label.text     = "$($script.name)"            start-process $script.fullname -wait -windowstyle hidden     }     $form.dispose() } $form.add_shown($shownformaction)  # show form $form.showdialog()

thanks in advance.

you're reusing same variable name list of messages , label showing message itself:

$messages = @("preparing install patch set..preparing stop related processes",                 "upgrading application",                 "copying missing folder",                 "applying patch",                 "starting stopped services",                 "checkcing healthyness of system after installation may take half hour...",                 "rebooting server"                 ) $messages = new-object system.windows.forms.label $messages.autosize = $true $messages.location = new-object system.drawing.point(10,50)

rename 1 of them (ie. use $messagelabel label):

$messagelabel = new-object system.windows.forms.label $messagelabel.autosize = $true $messagelabel.location = new-object system.drawing.point(10,50)

since increment progressbar 1 every step, can reuse progress bar value index $messages array:

foreach ($script in $scriptshome) {     $progressbar.increment(1)     $messagelabel.text = $messages[$progressbar.value - 1]     $label.text     = "$($script.name)"        start-process $script.fullname -wait -windowstyle hidden }

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
