3 posts in this topic

#1 ·  Posted (edited)


i'm building a "Jump To" registry key function and trying to get access to the regedit treeview control like this:

#include <GUIConstants.au3>
#include <GuiTreeView.au3>
#include <TreeViewConstants.au3>
#include <SendMessage.au3>
#include <WinAPI.au3>

Global $h_item

;~ Local $pid = ProcessExists("regedit.exe")

;~ If $pid Then
;~  $h_tree = WinHandFromPID($pid, "[CLASS:RegEdit_RegEdit]")
;~  WinActivate("[CLASS:RegEdit_RegEdit]", "")
;~ EndIf

WinWaitActive("[CLASS:RegEdit_RegEdit]", "")
;~ WinActivate("[CLASS:RegEdit_RegEdit]", "")
;~ WinSetState("[CLASS:RegEdit_RegEdit]", "", @SW_SHOW) ; activate
;~ WinSetState("[CLASS:RegEdit_RegEdit]", "", @SW_RESTORE) ; activate
;~ WinSetState("[CLASS:RegEdit_RegEdit]", "", @SW_RESTORE) ; activate

$h_tree = WinGetHandle("[CLASS:RegEdit_RegEdit]", "")
;~ $ret = _WinAPI_ShowWindow($h_tree, @SW_RESTORE)

$ctrl = ControlGetHandle($h_tree, "", "[CLASS:SysTreeView32]")

ConsoleWrite("$h_tree: " & $h_tree & @CRLF)
ConsoleWrite("$ctrl: " & $ctrl & @CRLF)

$show = GUICtrlCreateButton("Show", 70, 180, 70, 20)


;~ While 1
;~  Sleep(200)
;~ WEnd

Func Show()
    $result = ""

    _SendMessage($ctrl, $WM_SETFOCUS, 0, 0)
    If @error Then ConsoleWrite("error" & @CRLF)

    $h_item = _SendMessage($ctrl, $TVM_GETNEXTITEM, $TVGN_ROOT, 0)

    $split = StringSplit("HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders", "\")
    For $i=1 To $split[0]

        ConsoleWrite("item bevor findkey: " & $h_item & @CRLF)

        $h_item = FindKey($h_item, $split[$i])
        If $h_item = 0 Then Return
        _SendMessage($ctrl, $TVM_SELECTITEM, 0x0009, $h_item)

        ; expand tree
        _GUICtrlTreeView_Expand($ctrl, $h_item)


    MsgBox(0, "dsfsdf", "sdfsf")

Func FindKey($hItemParent, $sKey)

    $h_item = _SendMessage($ctrl, $TVM_GETNEXTITEM, $TVGN_CHILD, $hItemParent)
    ConsoleWrite("child : " & $h_item & " key: " & $sKey & " parent: " & $hItemParent & " parent text: " & _GUICtrlTreeView_GetText($ctrl, $hItemParent) & @CRLF)

    While $h_item <> 0
        Local $sItemText = _GUICtrlTreeView_GetText($ctrl, $h_item)
        ConsoleWrite("text : " & $sItemText & @CRLF)
        If $sItemText = $sKey Then Return $h_item

        $h_item = _SendMessage($ctrl, $TVM_GETNEXTITEM, $TVGN_NEXT, $h_item)
        ConsoleWrite("next : " & $h_item & @CRLF)
    ConsoleWrite("not found" & @CRLF)
    Return 0

WinWaitActive("[CLASS:RegEdit_RegEdit]", "")

See if that helps.

It doesn't work. But i was wondering why the item handle looks much longer in this case, so i added


and now it works and i not really know why. It's like an inspiration :D

      I have a script which uses a GUI with two buttons. It gets shown and hidden., and pressing the buttons (including their hotkeys) highlights the button, making you able to press enter the next time.
      However, I don't want that.
      I've tried using WinActivate() to make enter do things on another program, but the enter is still tied to the AutoIT GUI (which still has the button highlighted).
      Here's the important part of my code:
      $MY_GUI = GUICreate("Check.exe", 400, 300, ((@DesktopWidth / 2) - 200), -500) WinSetOnTop($MY_GUI, "", 1) ;Keeps the window on the top. $Button1 = GUICtrlCreateButton("Pass (Ctrl+P)", 40, 250, 120, 40, $WS_GROUP) GUICtrlSetFont(-1, 12, 400, 0, "MS Sans Serif") $Button2 = GUICtrlCreateButton("Fail (Ctrl+F)", 240, 250, 120, 40, $WS_GROUP) GUICtrlSetFont(-1, 12, 400, 0, "MS Sans Serif") $GUIText = GUICtrlCreateLabel("", 20, 10, 360, 230) GUICtrlSetFont(-1, 13, 400, 0, "MS Sans Serif") GUICtrlSetData($GUIText, Execute($stepMessage[$step])) $showGUI = "True" GUISetState(@SW_SHOW) While($showGUI = "True") $buttonPressed = GUIGetMsg() Switch $buttonPressed Case $Button1 ;Pass $pass = "True" $buttonPressed = 0 $showGUI = "False" GUISetState(@SW_HIDE) Case $Button2 ;Fail $buttonPressed = 0 $showGUI = "False" GUISetState(@SW_HIDE) While($message = "") $message = InputBox("Check.exe", "Please enter the reason the step failed." & @CRLF, "", "", 300, 200, ((@DesktopWidth / 2) - 150), -400) WEnd Return $message EndSwitch WEnd Local $pass = "False" ;Whether "Pass" or "Fail" was pressed. Local $failLog = xxxfunc($pass) ;Returns a message to log if the step failed. ##THIS CALLS THE CODE SNIPPET ABOVE## FileWrite($file, _Now() & ": Step " & $step & getStatus($pass) & "and took " & Ceiling(TimerDiff($timer) / 1000) & " seconds." & @CRLF) If($failLog <> "") Then FileWrite($file, "Logged comment: " & $failLog & @CRLF) EndIf WinActivate("[TITLE:ProgramName]") ;Hotkeys: HotKeySet("^{p}", "pressPass") HotKeySet("^{f}", "pressFail") Func pressPass() $buttonPressed = $Button1 EndFunc Func pressFail() $buttonPressed = $Button2 EndFunc  
      The GUI's button/hotkey pressing works correctly.
      The same WinActivate code works in another script of mine.
      Together, WinActivate is not take "Active" away from the GUI's last-pressed button. How do I fix this?
      Thank you in advance.

      Dear AutoIT Community.
      I am currently working on a program that will display lots of images in a scroll down GUI.
      I create the GUI based on the number of images, which works fine.
      But all images I place using GuiCtrlCreatePic above a threshold of around 32000 pixels (cant say exactly) are placed at negative locations and finally will reach 0 again
      and will then populate on top of the images placed there before.
      For $i = 1 To $Images[0] ; Get picture dimensions $hImage = _GDIPlus_ImageLoadFromFile($ImgRep & $Images[$i]) $iX = _GDIPlus_ImageGetWidth($hImage) $iY = _GDIPlus_ImageGetHeight($hImage) _GDIPlus_ImageDispose($hImage) ; Resize & place images in GUI $Pic[$i] = GUICtrlCreatePic($ImgRep & $Images[$i], $Spacer, Round($yPos, 0), $MaxImgWidth, $MaxImgWidth * ($iY / $iX)) $yPos = $yPos + $MaxImgWidth * ($iY / $iX) + $Spacer $log = $log & "|" & $yPos $currentlut = $Images[1] Next I have found a limit at 32767 pixels for some GUI elements when googling around.
      Can someone tell me how to circumvent that?

      Is there anyway to store word documents in Autoit GUI? For example I have a instruction sheet that I want to bundle up with the exe.

      So a user simply clicks the icon and the stored document will launch  (Something like how you can add objects like excel sheets in word documents )

      (I Know we can launch word files from script directory)

      Not sure if this is possible or if someone has already tackled this. Is it possible to embed PowerShell into a GUI? Autoit is great for quick function but sometime I need to run a command thru PowerShell. It be great to have PowerShell console embedded into the gui.
