File>New

[aslani]

I made a pulldown menu with the "New" selection and all I want it to do is to reset my GUI, meaning empty all variables and input boxes, etc.

I can use GUICtrlSetData() and GUICtrlSetState() for each variables but I have tons of variables and it's ugly.

There's gotta be an easier way. Any advice?

Keep the control IDs or handles in an array when you create them. Makes it easy to loop through them quickly and change something like text, enable/disable, check/uncheck, etc.

That's what I have right now and I don't like how it looks.

I was hoping that theres a function that already exist that can clear everything as if you just opened the GUI for the first time...but it seems that the task is for me.

No problem:

GuiDelete($hGUI)
$hGUI = GuiCreate("My GUI")

But, all seriousness aside, what do mean about 'how it looks'? If you could post some code for an example it would help to understand the problem.

Ok here's part of the code that I'm using.

$data = ""
$vArray = _ArrayCreate($data)
...
$user = IniRead(@ScriptDir & "\mmrConfig.ini", "Login", "Username", "")
$username = GuiCtrlCreateInput("" & $user, 100, 60, 55, 20)
_ArrayAdd($vArray, $username) ; This goes to every variable I want to reset thru out my script
...
$pass = IniRead(@ScriptDir & "\mmrConfig.ini", "Login", "Password", "")
$password = GuiCtrlCreateInput("" & $pass, 75, 85, 120, 20, $ES_PASSWORD)
_ArrayAdd($vArray, $password)
...
$file_path = GuiCtrlCreateCombo("", 75, 20, 200, 20)
_ArrayAdd($vArray, $file_path)
...
; Pull Down Menu
$filemenu = GUICtrlCreateMenu ("&File")
$f_login = GUICtrlCreateMenuItem ("&Login", $filemenu)
GUICtrlSetState(-1, $GUI_DEFBUTTON)
$f_new = GUICtrlCreateMenuItem ("&New", $filemenu)
$f_separator = GUICtrlCreateMenuitem ("",$filemenu,2)
$f_exit = GUICtrlCreateMenuItem ("E&xit", $filemenu)
...
While 1
$msg = GUIGetMsg()
Select
Case $msg = $f_new
For $i = 0 To UBound($vArray)-1 Step 1
GUICtrlSetData($vArray[$i], "")
Next
EndSelect
WEnd

Basically I don't like how _ArrayAdd($vArray, $some_var) gets repeated over and over, but the alternative is not pleasant to look at either. But I think this is the only way.

This is the kind of thing I use (not a full running demo):

$hGUI = GUICreate("etc...")

Dim $avInputs[1] = [0]; array of inputs to clear
Dim $avCombos[1] = [0]; array of combos default

$username = GUICtrlCreateInput($user, 100, 60, 55, 20)
_ArrayAdd($avInputs, ControlGetHandle($hGUI, "", $username))

; ...add more inputs

$file_path = GUICtrlCreateCombo("", 75, 20, 200, 20)
_ArrayAdd($avCombos, ControlGetHandle($hGUI, "", $file_path))

; ...add more combos

; ...detect operator wants to reset form controls...

_Reset()

Func _Reset()
    $avInputs[0] = UBound($avInputs) - 1
    For $n = 1 To $avInputs[0]
        GUICtrlSetData($avInputs[$n], ""); Clear text in all inputs
    Next
    
    $avCombos[0] = UBound($avCombos) - 1
    For $n = 1 To $avCombos[0]
        _GUICtrlComboSetCurSel($avCombos[$n], 0); select first index as default in all combos
    Next
EndFunc  ;==>_Reset

Note it save the control handles, not the ControlID, making some reset operations more reliable.

I haven't played around with handles yet since I don't really understand how it works. All I need is to simply empty all variables when "New" is selected.

Basically what my script does is to extract information from an Excel Spreadsheet, then place all data in an array to be logged into a database. So all I do is provide the Excel Form Number then my script does the rest (i.e. Open Excel -> Extract Data -> Close Excel -> Open/Activate Database -> Log Data -> Rinse and repeat)

So I have this list of Excel File Number in an array and the script goes thru that list, but if one of them has, for example, 10 items, then the one after it has 8 items, the left over 2 items are arrayed into the one with only 8 items. This is where the "New" option and emptying all variables comes into play.

As for now, what I have works the way I want it to (but I'm think I'll be studying handles some time soon )

Ok I used AU3Info.exe and the database program I'm using don't even display the handles like the other windows I have opened. :/

Ok, I got more problem.

I manage to clear the values in GUI variables, but all my non-GUI variables still keeps their value. Anybody have an idea on how to reset the non-GUI variables?

What do you mean by non-GUI variables? Such as labels? Global variables declared at the top of the script? Variables where? And why do they need to be cleared... shouldn't it reset itself when you enter in new values inside of the gui text boxes?

One technique that might work is to place the entire GUI creation inside a function. Then when you want to clear it just GUIDelete and re-execute the function.

Simple example:

#include <GUIConstants.au3>

$gui = GUICreate('', 200, 200)
$me_File = GUICtrlCreateMenu('&File')
$mi_New = GUICtrlCreateMenuItem('New', $me_File)

$gui_Child = _New($gui)
GUISetState(@SW_SHOW, $gui)
GUISetState(@SW_SHOW, $gui_Child)

While 1
    $gm = GUIGetMsg()
    Switch $gm
        Case $mi_New
            GUISetState(@SW_LOCK, $gui)
            GUIDelete($gui_Child)
            $gui_Child = _New($gui)
            GUISetState(@SW_SHOW, $gui_Child)
            GUISetState(@SW_UNLOCK, $gui)
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
WEnd


Func _New($hParent)
    Local $guiChild = GUICreate('', 200, 200, 0, 0, $WS_CHILD, Default, $hParent)
    GUICtrlCreateLabel('Label', 5, 5, 30, 20, $SS_CENTERIMAGE)
    GUICtrlCreateInput('Default', 40, 5, 100, 20)
    GUICtrlCreateCheckbox('Default unchecked', 5, 25, 150, 20)
    GUICtrlCreateCheckbox('Default checked', 5, 45, 150, 20)
        GUICtrlSetState(-1, $GUI_CHECKED)
    GUICtrlCreateCombo('', 5, 65, 150, 100)
        GUICtrlSetData(-1, 'One|Two|Three|Four', 'One')
    Return $guiChild
EndFunc

Sorry I completely lost track of this thread since I was too busy working on another project.

non-GUI variables as arrays, return value, etc.

#include <GUIConstants.au3>

$gui = GUICreate('', 200, 200)

$gui_Child = _New($gui)
GUISetState(@SW_SHOW, $gui)
GUISetState(@SW_SHOW, $gui_Child)

    $gm = GUIGetMsg()
    Switch $gm
        Case $mi_New
            GUISetState(@SW_LOCK, $gui)
            GUIDelete($gui_Child)
            $gui_Child = _New($gui)
            GUISetState(@SW_SHOW, $gui_Child)
            GUISetState(@SW_UNLOCK, $gui)
        Case $GUI_EVENT_CLOSE
            ExitLoop

    GUICtrlCreateInput('Default', 40, 5, 100, 20)
    GUICtrlCreateCheckbox('Default unchecked', 5, 25, 150, 20)
    GUICtrlCreateCheckbox('Default checked', 5, 45, 150, 20)
        GUICtrlSetState(-1, $GUI_CHECKED)
    GUICtrlCreateCombo('', 5, 65, 150, 100)
        GUICtrlSetData(-1, 'One|Two|Three|Four', 'One')
    Return $guiChild
EndFunc

Oooh, that might just work. I like it. Edited October 16, 2007 by aslani
