PlayZoneUK Posted May 28, 2022 Share Posted May 28, 2022 (edited) Good afternoon all, It’s been a while and I’m hoping someone can point me in the right direction… Background: I’m creating a utility to enable the administration of user accounts using water's fantastic Active Directory UDF ; I’ve got the basic functionality and now I’m working on the presentation. The controls which are of particularly interest are an input (Username) and a button (Search) Goal: I’d like for the button to be disabled until a user starts typing within the input which will fire off an event which enables the button. However if a user removes the contents from the input; the button is then disabled again. For the life of me I can't remember how to do that... Code Snippet: expandcollapse popup#include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Opt('GUIOnEventMode' , 1) Global $App = "Test Application" _BuildGUI() ; Loop until the user exits. While 1 Sleep(250) WEnd _Quit() Func _BuildGUI() Global $hGUI = GUICreate($App, 480, 80, -1, -1, BitOR($WS_CAPTION, $WS_POPUP, $WS_BORDER, $WS_CLIPSIBLINGS), $WS_EX_WINDOWEDGE) ; Create GUI GUICtrlCreateLabel("&Username:", 20, 18, 75, 20) ; Create Username label $inp_Username = GUICtrlCreateInput("", 100, 15, 290, 20) ; Create Username input GUICtrlSetOnEvent(-1,"_Check") ; Call _Check when exit Username input Global $btn_Search = GUICtrlCreateButton("&Search", 400, 15, 60, 20) ; Create Search Button GUICtrlSetOnEvent(-1, "_Search") ; Call _Search function when pressed Global $btn_Quit = GUICtrlCreateButton("&Quit", 400, 45, 60, 20) ; Create Quit Button GUICtrlSetOnEvent(-1, "_Quit") ; Call _Quit function when pressed GUICtrlSetState($btn_Search, $GUI_DISABLE) ; Disable Search Button GUISetState(@SW_SHOW, $hGUI) EndFunc Func _Check() GUICtrlSetState($btn_Search, $GUI_ENABLE) ; Ena;be Button EndFunc Func _Search() MsgBox(4096, $App, "Search for user...") ; DO SOMETHING EndFunc Func _Quit() GUIDelete($hGUI) ; Delete the previous GUI and all controls. Exit EndFunc Thanks in advance PlayZoneUK Edited May 28, 2022 by PlayZoneUK Words of Wisdom and Favourite Quotes: 'Nothing is impossible, despite what other people say and think, prove them wrong and show them what you can do!'

Subz Posted May 28, 2022 Share Posted May 28, 2022 Maybe something like: expandcollapse popup#include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Opt('GUIOnEventMode' , 1) Global $hGUI, $inp_Username, $btn_Search, $btn_Quit Global $App = "Test Application" _BuildGUI() While 1 Sleep(250) WEnd _Quit() Func _BuildGUI() $hGUI = GUICreate($App, 480, 80, -1, -1, BitOR($WS_CAPTION, $WS_POPUP, $WS_BORDER, $WS_CLIPSIBLINGS), $WS_EX_WINDOWEDGE) ; Create GUI GUICtrlCreateLabel("&Username:", 20, 18, 75, 20) ; Create Username label $inp_Username = GUICtrlCreateInput("", 100, 15, 290, 20) ; Create Username input GUICtrlSetOnEvent(-1,"_Check") ; Call _Check when exit Username input $btn_Search = GUICtrlCreateButton("&Search", 400, 15, 60, 20) ; Create Search Button GUICtrlSetOnEvent(-1, "_Search") ; Call _Search function when pressed $btn_Quit = GUICtrlCreateButton("&Quit", 400, 45, 60, 20) ; Create Quit Button GUICtrlSetOnEvent(-1, "_Quit") ; Call _Quit function when pressed GUISetState(@SW_SHOW, $hGUI) AdlibRegister("_EnableSearch") EndFunc Func _Check() GUICtrlSetState($btn_Search, $GUI_ENABLE) ; Ena;be Button EndFunc Func _Search() MsgBox(4096, $App, "Search for user...") ; DO SOMETHING EndFunc Func _Quit() GUIDelete($hGUI) ; Delete the previous GUI and all controls.

Solution pixelsearch Posted May 28, 2022 Solution Share Posted May 28, 2022 Hi Subz Your solution works fine. Though in these cases, I prefer to register WM_COMMAND and test $EN_UPDATE (or $EN_CHANGE) etc... It allows to enable/disable the button at the exact moment when the input field is filled/emptied, without that little "visual delay" due to AdlibRegister (max 250ms by default, though it maybe diminished but it will then check AdlibRegister more frequently) Also, WM_COMMAND is only triggered when the user interferes with the controls (which is less frequent than repeated checks to AdlibRegister) This is a version with a registered WM_COMMAND : expandcollapse popup#include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Opt('GUIOnEventMode' , 1) Global $hGUI, $inp_Username, $btn_Search, $btn_Quit Global $App = "Test Application" _BuildGUI() While 1 Sleep(250) WEnd _Quit() Func _BuildGUI() $hGUI = GUICreate($App, 480, 80, -1, -1, BitOR($WS_CAPTION, $WS_POPUP, $WS_BORDER, $WS_CLIPSIBLINGS), $WS_EX_WINDOWEDGE) ; Create GUI GUICtrlCreateLabel("&Username:", 20, 18, 75, 20) ; Create Username label $inp_Username = GUICtrlCreateInput("", 100, 15, 290, 20) ; Create Username input $btn_Search = GUICtrlCreateButton("&Search", 400, 15, 60, 20) ; Create Search Button GUICtrlSetOnEvent(-1, "_Search") ; Call _Search function when pressed GUICtrlSetState(-1, $GUI_DISABLE) $btn_Quit = GUICtrlCreateButton("&Quit", 400, 45, 60, 20) ; Create Quit Button GUICtrlSetOnEvent(-1, "_Quit") ; Call _Quit function when pressed GUISetState(@SW_SHOW, $hGUI) GUIRegisterMsg($WM_COMMAND, 'WM_COMMAND') EndFunc Func _Search() MsgBox(4096, $App, "Search for user...") ; DO SOMETHING EndFunc Func _Quit() GUIDelete($hGUI) ; Delete the previous GUI and all controls. Exit EndFunc Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam) Local $nNotifyCode = BitShift($wParam, 16) Switch $lParam Case GUICtrlGetHandle($inp_Username) Switch $nNotifyCode Case $EN_UPDATE ; "just before text is displayed." ; $EN_CHANGE would work too ("after the system updates the screen.") ; Local Static $iEn_Update = 0 ; $iEn_Update +=1 ; ConsoleWrite($iEn_Update & " $iEn_Update >" & GUICtrlRead($inp_Username) & "<" & @crlf) GUICtrlSetState($btn_Search, (GUICtrlRead($inp_Username) = "" ? $GUI_DISABLE : $GUI_ENABLE)) EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc Have a great sunday. argumentum, Subz and PlayZoneUK 2 1 Link to comment Share on other sites More sharing options...
Subz Posted May 29, 2022 Share Posted May 29, 2022 Hi PixelSearch To be honest having a lazy Sunday , WM_COMMAND is the better solution. PlayZoneUK and pixelsearch 1 1 Link to comment Share on other sites More sharing options...
PlayZoneUK Posted May 29, 2022 Author Share Posted May 29, 2022 @Subz & @pixelsearch thank you for your suggestions, before I went to sleep I had come across references to the WM_COMMAND and $EN_CHANGE. I'd attempted to implement it but I was only missing the following statement: GUICtrlSetState($btn_Search, (GUICtrlRead($inp_Username) = "" ? $GUI_DISABLE : $GUI_ENABLE)) I've incorporated the above line and utilised $EN_UPDATE into my code and it's working perfectly... Once again thank you both for your assistance it is much appreciated.
