Window Transparency

Recommended Posts

I just wanted to share an app I wrote. It allows you to adjust the transparency of visible windows.

#include <GUIConstants.au3>

GUICreate("iWindow", 220, 135, 0, 0, -1, $WS_EX_TOPMOST)
$repop = GUICtrlCreateButton("Repopulate List", 10, 10, 200, 20)
$winLabel = GUICtrlCreateLabel("Window:", 10, 40)
$win = GUICtrlCreateCombo("Select a Window Title", 10, 55, 200, 20)
$transLabel = GUICtrlCreateLabel("Visibility:", 10, 90)
$trans = GUICtrlCreateCombo("Select Visibility", 10, 105, 200, 20)
GUICtrlSetData(-1, "0%|5%|10%|15%|20%|25%|30%|35%|40%|45%|50%|55%|60%|65%|70%|75%|80%|85%|90%|95%|100%")
GUISetState()
repopList()

Func repopList()
      GUICtrlSetData($win, "|")
      $winList = WinList()
      For $i = 1 To $WinList[0][0]
    If $WinList[$i][0] <> "" And $WinList[$i][0] <> "Program Manager" And BitAND(WinGetState($WinList[$i][0]), 2) Then
          GUICtrlSetData($win, $WinList[$i][0])
    EndIf
      Next
      GUICtrlSetData($win, "Select a Window Title", "Select a Window Title")
EndFunc

Func setTrans()
      $perc = StringTrimRight($perc, 1)
      $transNum = $perc * 2.55
      WinSetTrans($winName,"",$transNum)
EndFunc

$msg = 0
While $msg <> $GUI_EVENT_CLOSE
      $msg = GUIGetMsg()

      Select
    Case $msg = $repop
          GUICtrlSetData($trans, "Select Visibility")
          repopList()
    Case $msg = $trans
          $winName = GUICtrlRead($win)
          $perc = GUICtrlRead($trans)
          If $winName <> "Select a Window Title" Then
        setTrans()
          EndIf
      EndSelect
Wend

You need to set the height on the combos to around 100 for it work on Win 2000. :)

Tried your script here and the combos were...well, kind of not working properly.

modded to fix visibility back to 100% upon exit of the app.

$perc = "100%" 
$winName = ""

Today is joystick day :)

I made a version that when you press a button on your joystick, it will set the trasparency of the current window based on the x-axis of the joystick. Pushing the joystick down exits.

#include <DllMem.au3>
#include <GUIConstants.au3>

Local $joy
Dim $coor[8]

$joy    = _JoyInit()

while $coor[1] < 65500
    $coor   = _GetJoy($joy,0)
    if $coor[7] Then WinSetTrans("","",($coor[0]/65536) * 255)
    sleep(250)
WEnd

WinSetTrans("","",255)

    Local $joy
    Global $JOYINFOEX_struct    = "dword(13)"

    $joy    = _DllMemCreate($JOYINFOEX_struct)
    if Not $joy Then Return 0
    _DllMemSet($joy,$JOYINFOEX_struct,0,_DllMemStructSize($JOYINFOEX_struct),0)
    _DllMemSet($joy,$JOYINFOEX_struct,0,255,1)
    return $joy
EndFunc
