This is a quick code to create a BUTTON , CHECKBOX and COMBO BOX and assign some action to them using “MessageLoop Format”.

The general message loop format is

While 1
$iMsg = GUIGetMsg()
...
...
WEnd

Action is put into the WHILE LOOP using the SWITCH and CASE STATEMENT.

The GUIGetMsg() function polls the GUI to see if any events have occurred. If an event has occurred it is assigned to the variable $nMsg and the status of the variable is checked in the SWITCH – CASE STATEMENT.

The script executes and displays the appropriate Message Box when the value in the  variable in the CASE STATEMENT matches the value stored in the $nMsg variable

The GUI resulting from the code below is generated using KodaForm designer which can be downloaded from here: Koda form designer

#include

#Region ### START Koda GUI section ### Form=
Global $Form1 = GUICreate("DataPandas", 536, 254, 192, 124)  ; this creates the GUI
Global $Button1 = GUICtrlCreateButton("PRESS ME", 32, 72, 137, 81)
Global $Combo1 = GUICtrlCreateCombo("Choose Me", 288, 72, 137, 25, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))
GUICtrlSetData(-1, "AutoIT is Awesome")
Global $Checkbox1 = GUICtrlCreateCheckbox("Checkbox", 184, 40, 89, 73)
GUISetState(@SW_SHOW) ; this displays the GUI
#EndRegion ### END Koda GUI section ###

While 1
	$nMsg = GUIGetMsg()
	Switch $nMsg
		Case $GUI_EVENT_CLOSE
			Exit
	    Case $Button1
			MsgBox(64,"You pushed...", "You pushed the BUTTON!")
		 Case $Combo1
			MsgBox(64, "You selected..", "You selected an item from the COMBO BOX")
		 Case $Checkbox1
			MsgBox(64, "You selected..", "You ticked the checkbox")


	EndSwitch
WEnd
