it's quite often, that someone asks how to change the texts of the MsgBox buttons or the InputBox buttons or how to change the position of ta MsgBox. Since years I use CBT hooks for that, but now I made a small UDF out of it for the ease of use. Of course you can build your own GUI or use already existing UDFs to do the same, but I like this way and you can hack (hook) the inbuild InputBox.



#include <WinAPI.au3>

Global Const $tagCBT_CREATEWND = "ptr lpcs;HWND tagCBT_CREATEWND"
Global Const $tagCREATESTRUCT = "ptr lpCreateParams;handle hInstance;HWND hMenu;HWND hwndParent;int cy;int cx;int y;int x;LONG style;ptr lpszName;ptr lpszClass;DWORD dwExStyle"

Global $g__hProcDlgBox = DllCallbackRegister("__DlgBox_CbtHookProc", "int", "int;int;int")
Global $g__TIdDlgBox = _WinAPI_GetCurrentThreadId()
Global $g__hHookDlgBox = _WinAPI_SetWindowsHookEx($WH_CBT, DllCallbackGetPtr($g__hProcDlgBox), 0, $g__TIdDlgBox)

Global Const $g__MaxDlgBtns = 5 ; maximum of 5 buttons to rename text
Global Const $g__MaxDlgItemId = 11 ; maximun ID of buttons to search is 11 as this is the maximun used in Messagebox

Global $g__DlgBoxPosX, $g__DlgBoxPosY, $g__DlgBoxWidth, $g__DlgBoxHeight
Global $g__aDlgBoxBtnText[$g__MaxDlgBtns]

Global $g__DlgBtnCount = 0



Func _DlgBox_SetButtonNames($TxtBtn1 = Default, $TxtBtn2 = Default, $TxtBtn3 = Default, $TxtBtn4 = Default, $TxtBtn5 = Default)
    $g__aDlgBoxBtnText[0] = $TxtBtn1
    $g__aDlgBoxBtnText[1] = $TxtBtn2
    $g__aDlgBoxBtnText[2] = $TxtBtn3
    $g__aDlgBoxBtnText[3] = $TxtBtn4
    $g__aDlgBoxBtnText[4] = $TxtBtn5

    $g__DlgBtnCount = @NumParams
EndFunc   ;==>_DlgBox_SetButtonNames

Func _DlgBox_SetPosition($x = Default, $y = Default) ;only for MsgBox, not working and not needed for InputBox
    $g__DlgBoxPosX = $x
    $g__DlgBoxPosY = $y
EndFunc   ;==>_DlgBox_SetPosition

Func _DlgBox_SetSize($w = Default, $h = Default)
    $g__DlgBoxWidth = $w
    $g__DlgBoxHeight = $h
EndFunc   ;==>_DlgBox_SetSize

Func _DlgBox_SetDefaults()
    $g__DlgBoxPosX = Default
    $g__DlgBoxPosY = Default
    $g__DlgBoxWidth = Default
    $g__DlgBoxHeight = Default
    For $i = 0 To UBound($g__aDlgBoxBtnText) - 1
        $g__aDlgBoxBtnText[$i] = Default
EndFunc   ;==>_DlgBox_SetDefaults

Func __DlgBox_CbtHookProc($nCode, $wParam, $lParam)
    Local $tcw, $tcs
    Local $iSearch = 0
    Local $ahBtn[$g__DlgBtnCount]
    If $nCode < 0 Then
        Return _WinAPI_CallNextHookEx($g__hHookDlgBox, $nCode, $wParam, $lParam)

    Switch $nCode
        Case 3 ;5=HCBT_CREATEWND
            If _WinAPI_GetClassName(HWnd($wParam)) = "#32770" Then ;Dialoig window class
                $tcw = DllStructCreate($tagCBT_CREATEWND, $lParam)
                $tcs = DllStructCreate($tagCREATESTRUCT, DllStructGetData($tcw, "lpcs"))

                If $g__DlgBoxPosX <> Default Then DllStructSetData($tcs, "x", $g__DlgBoxPosX)
                If $g__DlgBoxPosY <> Default Then DllStructSetData($tcs, "y", $g__DlgBoxPosY)
                If $g__DlgBoxWidth <> Default Then DllStructSetData($tcs, "cx", $g__DlgBoxWidth)
                If $g__DlgBoxHeight <> Default Then DllStructSetData($tcs, "cy", $g__DlgBoxHeight)
        Case 5 ;5=HCBT_ACTIVATE
            For $i = 1 To $g__MaxDlgItemId
                If IsHWnd(_WinAPI_GetDlgItem($wParam, $i)) Then
                    If $g__aDlgBoxBtnText[$iSearch] <> Default Then _WinAPI_SetDlgItemText($wParam, $i, $g__aDlgBoxBtnText[$iSearch])
                    $iSearch += 1
                    If $iSearch >= UBound($ahBtn) Then ExitLoop
    Return _WinAPI_CallNextHookEx($g__hHookDlgBox, $nCode, $wParam, $lParam)
EndFunc   ;==>__DlgBox_CbtHookProc

Func __DlgBox_UnregisterHook()
EndFunc   ;==>__DlgBox_UnregisterHook

Func _WinAPI_SetDlgItemText($hDlg, $nIDDlgItem, $lpString)
    Local $aRet = DllCall('user32.dll', "int", "SetDlgItemText", _
            "hwnd", $hDlg, _
            "int", $nIDDlgItem, _
            "str", $lpString)
    Return $aRet[0]
EndFunc   ;==>_WinAPI_SetDlgItemText


Simple example to see how to use it

#include "HookDlgBox.au3"

_DlgBox_SetButtonNames("1", "two", "3")
MsgBox(4, "Test 1", "Custom button texts")

_DlgBox_SetPosition(20, 20)
MsgBox(66, "Test 2", "Custom position and button texts")

_DlgBox_SetButtonNames("Submit", "Don't submit", "Don't know")
InputBox("Test 3", "Where were you born?", "Planet Earth")

_DlgBox_SetSize(800, 800)
InputBox("Test 4", "Where were you born?", "Planet Earth")

_DlgBox_SetSize(Default, 800)
MsgBox(66, "Test 5", "Strange but working")

_DlgBox_SetButtonNames(Default, "Wait", "What?")
_DlgBox_SetSize(Default, Default)
_DlgBox_SetPosition(500, 500)
MsgBox(66, "Test 6", "So far so good!")


MsgBox(6, "Test 7", "Default position and button texts")

Hope you like it.


Best regards

I was quite sure I repaired this. I first used DlgWnd but then I found out that Microsoft is talking about Dialog Boxes.

Here another example with other dialog boxes


#include <Misc.au3>
#include "HookDlgBox.au3"

; force german custum button texts for FileOpenDialog
_DlgBox_SetButtonNames("Datei öffnen", "Auswahl abbrechen")
FileOpenDialog("Test", @ScriptDir, "AutoIt scriptses (*.au3)")

 _DlgBox_SetPosition(500, 100)

_DlgBox_SetButtonNames("Lets go", "No no")

      I'm trying to use some inputboxes as radio buttons.
      This code seems to work ok, but don't know if there's is a better 'option'
      #include <GUIConstantsEx.au3> #include <GuiConstants.au3> GUIRegisterMsg($WM_COMMAND, "WM_COMMAND") Global $aInput[4] $hGUI = GUICreate("Test", 500, 500) $aInput[0] = GUICtrlCreateInput("Some text 1a", 10, 10, 200, 24) $aInput[1] = GUICtrlCreateInput("Some text 1b", 10, 40, 200, 24) $aInput[2] = GUICtrlCreateInput("Some text 2a", 10, 80, 200, 24) $aInput[3] = GUICtrlCreateInput("Some text 2b", 10, 110, 200, 24) GUISetState(@SW_SHOW, $hGUI) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd Func WM_COMMAND($hWnd, $msg, $wParam, $lParam) Local $nNotifyCode = BitShift($wParam, 16) ; high word Local $nID = BitAND($wParam, 0xFFFF) ; low word Local $hCtrl = $lParam Switch $nID Case $aInput[0] Switch $nNotifyCode Case $EN_SETFOCUS GUICtrlSetBkColor($aInput[0], 0x98FB98) GUICtrlSetBkColor($aInput[1], 0xD3D3D3) EndSwitch Case $aInput[1] Switch $nNotifyCode Case $EN_SETFOCUS GUICtrlSetBkColor($aInput[0], 0xD3D3D3) GUICtrlSetBkColor($aInput[1], 0x98FB98) EndSwitch Case $aInput[2] Switch $nNotifyCode Case $EN_SETFOCUS GUICtrlSetBkColor($aInput[2], 0x98FB98) GUICtrlSetBkColor($aInput[3], 0xD3D3D3) EndSwitch Case $aInput[3] Switch $nNotifyCode Case $EN_SETFOCUS GUICtrlSetBkColor($aInput[2], 0xD3D3D3) GUICtrlSetBkColor($aInput[3], 0x98FB98) EndSwitch EndSwitch ; Proceed the default Autoit3 internal message commands. ; You also can complete let the line out. ; !!! But only 'Return' (without any value) will not proceed ; the default Autoit3-message in the future !!! Return $GUI_RUNDEFMSG EndFunc ;==>WM_COMMAND Would you recommend using _WinAPI_GetFocus instead?

      HI everybody! It's been a (very) long time since I posted something useful!
      Here I come with a new functions that I needed in a project that needs many different forms to insert different data into a database. Instead of creating a different Koda form for each data type, I decided to create this function, inspired by this one (from the excellent IUP GUI library).
      To create an input dialog, you first must create a JSON definition of this dialog. Simple example of a login form:
      { title: "Dialog Title", controls: [ {type:"label", value:"Please login"}, {type:"input", id:"user", label:"User name"}, {type:"input", id:"pass", label:"Password", style:$ES_PASSWORD}, {type:"check", id:"remember", label:"Remember me", value:true} ] } Then pass it to the advInputBox function:
      #include "advInputBox.au3" Dim $oRet = advInputBox($sJSON) If @error Then MsgBox(64, "Example1", "Dialog canceled") Else MsgBox(64, "Example1", "Return: " & Json_Encode($oRet, 128)) ; you can access individual values by ids: ; Json_ObjGet($oRet, "username") ; Json_ObjGet($oRet, "password") ; Json_ObjGet($oRet, "remember") EndIf And you will get an InputBox like this one:

      The code is on GutHub

      Sometimes when I call several MsgBox's they start popping up under other windows, which the requires ALT + TAB or click the taskbar icon.
      I just wanted to share this workaround:
      Just add a simple GUI in your program:
      #include <GUIConstantsEx.au3> $Form1 = GUICreate("Form1", 1, 1, 0, 0) GUISetState(@SW_SHOW) The GUI window size here is 1x1 so it will be nearly invisible, and at the top-left of your screen.
      It seems as long as that GUI is there all MsgBox's appear on top!
      I only tend to create several MsgBox's in a row when I'm actually writing and testing scripts, so the GUI being there is no big deal (I just remove/comment the GUI creation right before I build the .EXE).
      Have a great day!!!

      Hi guys,
      So I am trying to automate a task and this task has an input box with an already set character "9". 
      I have just decided that I don't really need the input as an option but it's good to leave however for this instance I would like it to run past this point automatically. I've tried numerous ways to try and automate the use of the "OK" button using ControlClick and various other options. I just can't seem to see where this point in the script is. Scoured the forums for anything similar but didn't have any luck finding anything. Sorry to be a pain and I hope someone can help, if I haven't explained in enough detail please don't hesitate to ask for more.
      Many thanks,
      Local $len Local $n Local $buff Local $aMyDate $Len = InputBox("Test",$msgPrompt,"9") $len = StringStripWS($len,$STR_STRIPALL) ;Check that user has entered a vaild password length if not StringIsDigit($len) or $len = 0 Then MsgBox(48,"Error","Invaild Integer was entered" & @CRLF & "Program will now exit.") Exit EndIf ;This creates the random password. for $i = 1 to $Len ;Pick a random char between 1 and the pwsMask Length $n = int(random(1,StringLen($pwsMask))) ;Concat each char that has been picked out of pwsMask to $buff $buff = $Buff & StringMid($pwsmask,$n,1) Next
