determining which dropdown is selected without GUICtrlRead

10 posts in this topic

i've been searching the forums but cant quite find a way to do what i need. i have a gui that is supposed to read the removable drives into an array and display them, along with other information in a drop down box. then i want the program to run commands based on what option is selected. the problem i'm facing is that once the array has been parsed into the gui with the additional info, i cant figure a way to keep the array associated with the selected item in the dropdown so that when an option is selected i can still work with the array itself and not all the extra information added for the user's sake. and i can't really just use GUICtrlRead and parse in back because thats just not going to work for my purposes. here's what i have so for:

#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
$aArray = DriveGetDrive("REMOVABLE")
$Form1_1 = GUICreate("Form1", 615, 437, 264, 339)
$Label1 = GUICtrlCreateLabel("Select removeable drive to load Windows onto:", 16, 8, 227, 17)
$Combo1 = GUICtrlCreateCombo("", 32, 80, 445, 25, BitOR($CBS_DROPDOWNLIST,$CBS_AUTOHSCROLL))

If @error Then
; An error occurred when retrieving the drives.
MsgBox(4096, "DriveGetDrive", "No removable drives found or some other error occured.")
Else
For $i = 1 To $aArray[0]
$label = DriveGetLabel($aArray[$i])
if $label="" then $label ="[no label]"
;~ MsgBox(4096,"",$aArray[$i])
GUICtrlSetData(-1, $label& " (" &StringUpper($aArray[$i]) & ")   " &   Round(DriveSpaceTotal($aArray[$i]), 0) & " MB Total" & "  Windows Volume ID: " & DriveGetSerial($aArray[$i]))
Next
EndIf

;~ GUICtrlSetState(-1, $GUI_DISABLE)
GUISetState(@SW_SHOW)
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
  Case $GUI_EVENT_CLOSE
;~    MsgBox(4096,"test",GUICtrlRead($Combo1,1))
   Exit
EndSwitch
WEnd

the easiest and most effective thing i can think of is to somehow query the order number of the item in the drop down is selected (meaning the nth option is selected) and plug that into my $aArray. i just cant think of how to do it. any help would be appreciated.

bobbintb,

You could read the combo, extract the Drive letter and then search the array for that letter like this: :)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Combo1
            $aRet = _StringBetween(GUICtrlRead($Combo1), "(", ")")
            $iIndex = _ArraySearch($aArray, $aRet[0])
            If Not @error Then
                MsgBox(0, "Drive", "Array Index = " & $iIndex & @CRLF & "Drive: " & $aArray[$iIndex])
            EndIf
    EndSwitch
WEnd

Any use? ;)

i thought about that but if anything else in the string, like the label, has parenthesis then that could break something. is there a way to attach a variable to the dropdown? in the loop where GUICtrlSetData is parsing out the extra info, maybe i can also assign a numerical value to each dropdown option. then i can reference it with the array. could i use GUICtrlSetData to set more than one piece of data to the control (an array maybe), and only display to the user the part that i wish?

id like to avoid using GUICtrlRead because there are too many ways it could break the script in this instance.

You are determining the format of the combo entries - just ensure that there is nothing else in parentheses. :)

And even if you do put several items in parentheses, _StringBetween returns an array of all matches, so all you have to do is to use the correct element. :)

Why do you need to access the array again anyway? Surely just getting the drive letter from the combo entry is enough as that is all the array contains? ;)

i could just get the drive letter from the combo entry but then i would have to plan for all script breaking eventualities, such as the drive label having parenthesis and determining if what's between the parenthesis is the actual drive letter or part of the drive label.

instead of getting the list of removable drives and from that list make a gui with extra info for the user and then reading the control to see what the user selected and parsing it out and making sure that what the script thinks is the drive letter is actually the drive letter, it seems easier for me and more precise do it another way.

i had an idea to take the array of drive letter and add another dimension that contains the additional info for the user, then populate the gui with that info. that way i can link the actual drive letter in the first dimension of the array (as opposed to parsed one) to the GUI info in the second, so that when the script checks which item was selected, it can compare the GUICtrlRead with the correct info in the array to make certain the drive letter is correct. now i just need to add a second dimension to the existing array, if i can figure out how to do that.

I think there is a UDF around here somewhere to do that - look in the sigs of BrewManNH or guinness. If you cannot find it, use UBound to find the size of the returned array, use that to declare a 2D array of the correct size and then loop through the first array to fill the second. ;)

Here's one way of doing it.

#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
$aArray = DriveGetDrive("REMOVABLE")
$Form1_1 = GUICreate("Form1", 615, 437, 264, 339)
$Label1 = GUICtrlCreateLabel("Select removeable drive to load Windows onto:", 16, 8, 227, 17)
$Combo1 = GUICtrlCreateCombo("", 32, 80, 445, 25, BitOR($CBS_DROPDOWNLIST, $CBS_AUTOHSCROLL))
$Button = GUICtrlCreateButton(" Read ", 32, 150)
If @error Then
    ; An error occurred when retrieving the drives.
    MsgBox(4096, "DriveGetDrive", "No removable drives found or some other error occured.")
Else
    For $i = 1 To $aArray[0]
        $label = DriveGetLabel($aArray[$i])
        If $label = "" Then $label = "[no label]"
        GUICtrlSetData($Combo1, $label & " (" & StringUpper($aArray[$i]) & ")   " & Round(DriveSpaceTotal($aArray[$i]), 0) & " MB Total" & "  Windows Volume ID : " & DriveGetSerial($aArray[$i]))
    Next
EndIf
GUISetState(@SW_SHOW)
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button
            $sCombo = GUICtrlRead($Combo1)
            ConsoleWrite("Combo contents = " & $sCombo & @CRLF)
            For $i = 1 To $aArray[0]
                If StringInStr($sCombo, $aArray[$i]) Then
                    ConsoleWrite("Drive letter chosen = " & $aArray[$i] & @CRLF)
                EndIf
            Next
    EndSwitch
WEnd

Uses the contents of the combobox and the contents of the array without altering either one. Seeing as how drive labels can't contain the colon, there's no way to give a drive a label with one. So this search can't fail because unless you do something like put colons in the combo contents the only time it will match the string to the array is when the drive letters match.

EDIT: I just realized that you had a colon in the combo box information, see the line in the code above which corrects this. I added a space between "Windows Volume ID" and the following colon so it won't misread that line as a drive letter. Note, this would ONLY affect something if you had a D: drive that was also a removable drive.

Or, you can use the functions designed to do this that are built into the listbox api.

Sets the application defined value for each internal listbox item.

The AutoIt native Combobox is not using this parameter, it is always 0

or you can use the UDF combobox, either way, this is how you do it.

#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <GuiListBox.au3>
#include <GuiComboBox.au3>

$aArray = DriveGetDrive("REMOVABLE")
$Form1_1 = GUICreate("Form1", 615, 437, 264, 339)
$Label1 = GUICtrlCreateLabel("Select removeable drive to load Windows onto:", 16, 8, 227, 17)
$Combo1 = GUICtrlCreateCombo("", 32, 80, 445, 25, BitOR($CBS_DROPDOWNLIST, $CBS_AUTOHSCROLL))
$Button = GUICtrlCreateButton(" Read ", 32, 150)

$tInfo = 0
$hList = 0
$iIdx = 0

If _GUICtrlComboBox_GetComboBoxInfo($Combo1, $tInfo) Then $hList = DllStructGetData($tInfo, "hList")

If @error Then
; An error occurred when retrieving the drives.
MsgBox(4096, "DriveGetDrive", "No removable drives found or some other error occured.")
Else
For $i = 1 To $aArray[0]
  $label = DriveGetLabel($aArray[$i])
  If $label = "" Then $label = "[no label]"
  GUICtrlSetData($Combo1, $label & " (" & StringUpper($aArray[$i]) & ")   " & Round(DriveSpaceTotal($aArray[$i]), 0) & " MB Total" & "  Windows Volume ID: " & DriveGetSerial($aArray[$i]))
  $iIdx = _GUICtrlComboBox_GetCount($Combo1)
  If @error Or $iIdx = -1 Then ContinueLoop
  _GUICtrlListBox_SetItemData($hList, $iIdx - 1, $iIdx) ;use a 1-based index
Next
EndIf

GUISetState(@SW_SHOW)
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
  Case $GUI_EVENT_CLOSE
   Exit
  Case $Button
   $iIdx = _GUICtrlListBox_GetItemData($hList, _GUICtrlComboBox_GetCurSel($Combo1))
   If $iIdx >= 1 Then ConsoleWrite("Drive letter chosen = " & $aArray[$iIdx] & @CRLF)
EndSwitch
WEnd
