Recommended Posts

luis713

i want to choose from a combo box between NTFS and FAT, if i choose NTFS i want to limit the number of characters of an input to 32 and if i choose FAT i want to limit it to 11 characters, how is this possible? i want to do it without clicking a button, thanks :graduated:

here is my code

#include



GUICreate("", 200, 120)

$input = GUICtrlCreateInput("", 10, 60, 180, 20)

$checkBox = GUICtrlCreateCheckbox("Activate combo", 10, 10, 100, 20)

$combo = GUICtrlCreateCombo("", 50, 30, 100, 100)

GUISetState(@SW_SHOW)

GUICtrlSetData($combo, "NTFS|FAT32|FAT", "NTFS")





While 1

$msg = GUIGetMsg()

;Enable or disbable the combo when checked

If GUICtrlRead($CheckBox) = $GUI_CHECKED Then

If BitAND(GUICtrlGetState($Combo), $GUI_ENABLE) <> $GUI_ENABLE Then

GUICtrlSetState($combo, $GUI_ENABLE)

EndIf

EndIf

If GUICtrlRead($CheckBox) = $GUI_UNCHECKED Then

If BitAND(GUICtrlGetState($combo), $GUI_disable) <> $GUI_disable Then

GUICtrlSetState($combo, $GUI_disable)

EndIf

EndIf

Select

case $msg = $GUI_event_Close

Exit

EndSelect

WEnd

Here's one way of doing it. It enables and disables the combobox depending upon whether you check or uncheck the checkbox, then sets the limit for the inputbox depending upon what you select in the combo. It's initially set to a limit of 32 characters, because NTFS is the default, but will reset the limit if you change to FAT or FAT32. It also reads what you've put into the input box, if anything, and trims the excess characters if you select the lower limit.

#include <GUIConstantsEx.au3>
GUICreate("", 200, 120)

$input = GUICtrlCreateInput("", 10, 60, 180, 20)

$checkBox = GUICtrlCreateCheckbox("Activate combo", 10, 10, 100, 20)

$combo = GUICtrlCreateCombo("", 50, 30, 100, 100)
GUICtrlSetState(-1, $GUI_DISABLE)

GUISetState(@SW_SHOW)

GUICtrlSetData($combo, "NTFS|FAT32|FAT", "NTFS")

While 1

     $msg = GUIGetMsg()

     Select

          Case $msg = $GUI_event_Close
               Exit
          Case $msg = $checkBox
               If GUICtrlRead($checkBox) = $GUI_CHECKED Then
                    GUICtrlSetState($combo, $GUI_ENABLE)
                    GUICtrlSetLimit($input, 32)
               Else
                    GUICtrlSetState($combo, $GUI_DISABLE)
               EndIf
          Case $msg = $combo
               If GUICtrlRead($combo) = "NTFS" Then
                    GUICtrlSetLimit($input, 32) ; limits the input to 32 chars.
               Else
                    GUICtrlSetLimit($input, 11) ; limits the input to 11 chars.
                    GUICtrlSetData($input, StringLeft(GUICtrlRead($input), 11)) ; reads what's in the input and trims anything over 11 chars.
               EndIf
     EndSelect

WEnd
