Solved - Combo Clear Only Selection String

Recommended Posts

Xandy

Hi I'm struggling to clear the display text of of a GUI control combo selection string.

I would like to clear the selection like it is clear after it is populated, but not remove any items from the list.

Here is a small example.

#include <GuiComboBox.au3>
#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>

; Create GUI
$hgui= guicreate("Clear ComboBox Edit Text", 320, 200)
$control_combo= guictrlcreatecombo("", 10, 10, 250, 20, $CBS_DROPDOWNLIST)
$control_clear_button= guictrlcreatebutton("Reset Blank Combo Selection String", 10, 40, 200, 20)
guisetstate()
guictrlsetdata($control_combo, "a|b|c"); Populate Combo

while 1
    switch guigetmsg()
        case $control_clear_button
            guictrlsetdata($control_combo, ""); This clears the entire list frustrating me

        case $gui_event_close
            exitloop
    endswitch;guigetmsg()
wend;main loop
Does anyone one know how I can reset the selection to "", clear, empty set?

I've tried SetEditText but doesn't work CBS_DROPDOWNLIST.

SOLVED:

Sorry I thought I had tried this: _GUICtrlComboBox_SetCurSel($control_combo, -1) is the solution.

      So I'm needing a (better) way to get the selection in an edit control, while knowing which end of the selection is active vs anchor (ie, if you're holding shift while moving with the arrow keys, which end of the selection is moving and which is not). Since _GUICtrlEdit_GetSel() only returns the start and end positions, in the order of smallest to largest, if you were to pass that back to the _GUICtrlEdit_SetSel(), the user's selection could end up "backwards".
      My solution has been this function:
      Func _GUICtrlEdit_GetSelByAnchor($hWnd) ; Get selection range with anchor in first index If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd) Local $aActive, $aSelection = _GUICtrlEdit_GetSel($hWnd) ; Get base selection If $aSelection[0] <> $aSelection[1] Then ; Only proceed if actual selection range _GUICtrlEdit_SetSel($hWnd, -1, 0) ; Deselect, leaving only the active point $aActive = _GUICtrlEdit_GetSel($hWnd) ; Record the active point If $aActive[0] = $aSelection[0] Then ; If the active point is equal to the original first index ; Swap the original selection points (putting the anchor in [0] and active in [1]) $aSelection[0] = $aSelection[1] $aSelection[1] = $aActive[0] EndIf _GUICtrlEdit_SetSel($hWnd, $aSelection[0], $aSelection[1]) ; Reset selection to the original points EndIf Return $aSelection EndFunc The problem with this, as you may have already guessed from the two SetSel calls, is that calling it in a tight loop causes a lot of flickering. Is there a better, more reliable way to do what I'm looking for?

      Hello, I am getting this error message when running my script:
      Case $aButiD[0] To $aButiD[$iTotButtons - 1]
      Case ^ ERROR
      Error:  Array variable has incorrect number of subscripts or subscript dimension range exceeded.
       
      The script's purpose is to read my ini file and create buttons for the sections and section contents.
      The first part of the script creates buttons for the sections of the ini, once you click on the section button it should open another set of buttons of all the contents under the section
      In this case, the section in the .ini file is called "TPA"
      on the Func flavorco()
      It opens the contents of "TPA" into buttons.
      Right now, the section it is reading is determined by $sSection.
      It is only when I try to change $sSection = "TPA"
      to
      $sSection = $flavorco
      that the error starts to appear
       
      Here is the script
      #include <MsgBoxConstants.au3> #include <WinAPIFiles.au3> #include <Array.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <ButtonConstants.au3> $optbar = IniReadSectionNames("test.ini") If Not IsArray($optbar) Then Exit Local $Button[UBound($optbar) - 1] $mGUI = GUICreate('Restock Flavor Ingredients', 10 + (130 * UBound($optbar)), 100) For $x = 1 To UBound($optbar) - 1 $var = IniReadSection("test.ini", $optbar[$x]) If @error Then ContinueLoop $X_Coord = 10 + (($x - 1) * 100) $Button[$x - 1] = GUICtrlCreateButton($optbar[$x], $X_Coord, 30, 70, 30) Next GUISetState() While 1 $mMsg = GUIGetMsg() If $mMsg = $GUI_EVENT_CLOSE Then GUIDelete($mGUI) ExitLoop EndIf For $i = 0 To UBound($Button) - 1 If $mMsg = $Button[$i] Then MsgBox(0, '$Msg = ' & $mMsg, GuiCtrlRead($Button[$i]) & ' Pressed', 2) Global $flavorco = $Button ; sets the flavor company's variable Call('flavorco') EndIf Next WEnd Func flavorco() ;opened flavor company's flavors MsgBox(0, '$Msg = ' & $mMsg, GuiCtrlRead($Button[$i]) & $flavorco, 0) Local $sFilePath = @ScriptDir & "\Test.ini" Local $sSection = $Button Local $aArray = IniReadSection($sFilePath, $sSection) _ArrayDelete($aArray, 0) ;_ArrayDisplay($aArray) Local $iIndex Local $iTotButtons = UBound($aArray) Local $iNumPerRow = 5 Local $iButWidth = 100 Local $iButDepth = 30 Local $aButiD[$iTotButtons] Local $hGUI = GUICreate('Ingredients Stock "' & $sFilePath & '"', 10 + ($iButWidth + 10) * $iNumPerRow, _ 10 + Ceiling($iTotButtons / $iNumPerRow) * ($iButDepth + 10), -1, $WS_EX_TOPMOST) For $i = 0 To $iTotButtons - 1 ; $x = $iXBorder + (($iRectWidth + $iSpacing) * Mod($i, $iNumCols)) $x = 10 + (($iButWidth + 10) * Mod($i, $iNumPerRow)) ; $y = $iYBorder + (($iRectDepth + $iSpacing) * Int($i / $iNumCols)) $y = 10 + (($iButDepth + 10) * Int($i / $iNumPerRow)) $aButiD[$i] = GUICtrlCreateButton($aArray[$i][0], $x, $y, $iButWidth, $iButDepth) ;, $BS_NOTIFY) Next GUISetState(@SW_SHOW) While 1 $msg = GUIGetMsg() Switch $msg Case $GUI_EVENT_CLOSE GUIDelete($hGUI) ExitLoop Case $aButiD[0] To $aButiD[$iTotButtons - 1] ;clicking on a flavor name $iIndex = ($msg - $aButiD[0]) $RSINGRflavor = $aArray[$iIndex][0] ;flavor name $RSINGRml = $aArray[$iIndex][1] ; ml $RSINGRgal = $aArray[$iIndex][1]*0.000264172 ;converts ml to gal Call('openflavor') EndSwitch WEnd EndFunc Func openflavor() #Region ### START Koda GUI section ### Form=F:\Karl\AutoIt\FJ-Stock JP\GUI Forms\RSINGRSUBFORM.kxf ;opens flavor to view stock and restock submit $RSINGRSUBFORM = GUICreate($sSection & " " & $RSINGRflavor, 242, 213, 530, 269) $RSINGRFlavorTitle = GUICtrlCreateLabel($sSection & " " & $RSINGRflavor, 32, 8, 200, 28) GUICtrlSetFont(-1, 16, 800, 0, "MS Sans Serif") $RSINGRstockcaption = GUICtrlCreateLabel("Current Stock in ml:", 16, 48, 96, 17) $RSINGRstockml = GUICtrlCreateLabel($RSINGRml, 120, 48, 114, 25) GUICtrlSetFont(-1, 8, 800, 0, "MS Sans Serif") $RSINGRInput = GUICtrlCreateInput("ml", 40, 112, 153, 21) $RSINGRSUBMIT = GUICtrlCreateButton("SUBMIT", 16, 152, 81, 33) $RSINGRCLOSE = GUICtrlCreateButton("CLOSE", 145, 151, 81, 33) $RSINGRgalcaption = GUICtrlCreateLabel("Current Stock in gal:", 16, 80, 97, 17) $RSINGRstockgal = GUICtrlCreateLabel($RSINGRGAL, 120, 80, 114, 25) GUICtrlSetFont(-1, 8, 800, 0, "MS Sans Serif") GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### ; $msg = "" While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE GUIDelete($RSINGRSUBFORM) ExitLoop Case $RSINGRCLOSE GUIDelete($RSINGRSUBFORM) ExitLoop EndSwitch WEnd EndFunc  
      Any help is much appreciated!  Thanks.
      My guess is that $Button isn't an actual string??  Whenever I use msgbox it shows up the string exactly, no numbers attached.  So i'm not sure whats going on here.

      Hello again,
      I'm trying to use the FileMove function to rename a bunch of text files.
      Some of the files have "_1" at the end of their name, for example, "File123_1.txt". I want to remove the "_1" so it would become "File123.txt".
      What I currently have...
              FileMove($sSource & "\*_1.txt", $sDestination & "\*.txt")
      But since I'm using a wildcard, it doesn't appear to be working. I think it's just replacing .txt with .txt. Am I going about this the wrong way? How can I use wildcards and still accomplish this?
      Any help is greatly appreciated ^__^

      I have date in the string format as "DD-MM-YYYY".
       
      I need to get yesterday's date from it.
      I tried converting this from _DateTimeFormat but not working.
      Is there any direct UDF available to get this.?

      Hi, i want to read a particular string from a text file using autoit. i wish to read it without explicitly opening the text file. the copied string should be then transferred to an excelbook (again, no need to explicitly open the excel book)... 

      with reference to my screenshot attached, my input to the  'script'' is going to be 0017-0008, and the script should copy the highlighted two lines from the input file to excel
      thanks
