Grax Posted May 28, 2008 Share Posted May 28, 2008 Ok I have a ComboBox that is a Drop Down List. If the user selects an invalid selection, I pop-up a msgbox and display an error and then set focus back on the ComboBox. The displayed item is still the invalid selection the user selected. This would be fine if the user couldn't go onto another input until the error was corrected. However the user can click elsewhere or tab to the next input without seeing the error again. So how to I set the Drop Down List back to it's default of nothing selected? I'd rather delete the input and then recreate it. Any other suggestions? I guess along these same lines. How do I allow a user to set the selection of a drop down list back to nothing? The input isn't required and should they change their mind about inputing it I want them to be able to select nothing. Thanks, Andrew Link to comment Share on other sites More sharing options...
JRowe Posted May 28, 2008 Share Posted May 28, 2008 Create an item whose text is just a space in the first slot, like so, when you are making your list. #include <GUIConstants.au3> #include <GuiComboBoxEx.au3> $Form1 = GUICreate("Form1", 186, 55, 193, 125) $Combo1 = GUICtrlCreateCombo("", 16, 16, 145, 25, BitOR($CBS_DROPDOWNLIST,$CBS_AUTOHSCROLL)) $ComboData = " |1|2|3|4|5|6" GUICtrlSetData(-1, $ComboData,0) GUISetState(@SW_SHOW) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Combo1 Selectionchanged(GUICtrlRead ($Combo1)) EndSwitch WEnd Func Selectionchanged($ListOption) MsgBox(0, "You chose item:" & $ListOption , "Now resetting to index[0] (the first position)") _GUICtrlComboBox_SetCurSel($Combo1, 0) EndFunc In order to access the control(easily, at least,) you'll need to include <GuiComboBoxEx.au3> This will let you use the following functions to access and set the currently selected item. _GUICtrlComboBoxEx_GetCurSel _GUICtrlComboBoxEx_SetCurSel The validation is all up to you [center]However, like ninjas, cyber warriors operate in silence.AutoIt Chat Engine (+Chatbot) , Link Grammar for AutoIt , Simple Speech RecognitionArtificial Neural Networks UDF , Bayesian Networks UDF , Pattern Matching UDFTransparent PNG GUI Elements , Au3Irrlicht 2Advanced Mouse Events MonitorGrammar Database GeneratorTransitions & Tweening UDFPoker Hand Evaluator[/center] Link to comment Share on other sites More sharing options...
