ADODB.RecordSet filter partial match?

Recommended Posts

Hi guys, im trying to filter an Array/listview with ~150k rows, the fastest way to do this seems to be by putting it into ADO XML format and using filters. I'd like to show the filtered results in the listview.

I'm having trouble with getting a partial match filter to work. Here is an example reproducer. You enter some characters to filter on in the input and click the button to filter.

#include <GUIConstants.au3>
#Include <GuiListView.au3>

Global $GUI, $adoRsItems, $ListView1, $Button1, $Button2, $Button3, $Button4, $Button5, $Button6
Local $I, $J, $K, $Txt, $DataFile

$GUI = GUICreate("ADORS ListView Filtering", 633, 447, -1, -1)
$input = GUICtrlCreateInput("", 10, 180, 50)
$Button4 = GUICtrlCreateButton("Filter", 10, 200, 50, 50, 0)

$ListView1 = GUICtrlCreateListView("ID|Description|Type", 72, 8, 553, 425)
$DataFile = StringReplace(@ScriptFullPath, ".au3", ".Xml")
$adoRsItems = ObjCreate( "ADODB.RecordSet" )

With $adoRsItems
    .CursorLocation = 3; adUseClient
    .CursorType = 2; adOpenDynamic
    .LockType = 2; adLockPessimistic
    If FileExists($DataFile) Then
       .Open($DataFile) ; Load From XML File
    Else ; Define Columns
      .Fields.Append("ID", 3, 5, 32); adInteger, 5, adFldIsNullable
      .Fields.Append("Description", 200, 400, 32); adVarChar, 400, adFldIsNullable
      .Fields.Append("Type", 200, 40, 32)
      ; Populate with Data
      For $I = 1 to 50
          .Fields(0).Value = $I
          $Txt = " "
          For $J = 0 to Random(10, 20, 1)
          If Random() < 0.5 Then
             $Txt = $Txt & Chr(Random(Asc("A"), Asc("Z"), 1))
             $Txt = $Txt & Chr(Random(Asc("a"), Asc("z"), 1))
          Next ;$J
          .Fields(1).Value = "Description-" & $I & $Txt
          If $I < 30 Then
             .Fields(2).Value = "Type-1"
             .Fields(2).Value = "Type-2"
      Next ; $I
      .Save($DataFile, 1) ; Save to XML File

While 1
    $I = GUIGetMsg()
    Switch $I
    Case $Button4
         $adoRsItems.Filter = "Description='*"&GUICtrlRead($input)&"*'"

Func PopulateListView()
Local $I, $J, $K, $Txt
   ;Msgbox(0, "LV Populate", "Populating with " & $adoRsItems.RecordCount() & " Items", 5)
   _GUICtrlListView_DeleteAllItems(GUICtrlGetHandle($ListView1)); Clear ListView
   If $adoRsItems.EOF() Then
      MsgBox(64, "Filter Failed", "Filter Excluded All Items." & @CRLF & "Filter=" & $adoRsItems.Filter & @CRLF & @CRLF & "Reverting to All Items Display.", 5)
      $adoRsItems.Filter = 0
      GUICtrlSetState($I, $Button1)
   $J = $adoRsItems.Fields.Count() - 1
   While NOT $adoRsItems.EOF()
     $K = $adoRsItems.Fields("ID").Value
     For $I = 0 To $J
         $Txt = $adoRsItems.Fields($I).Value
        If $I = 0 Then
           $K = _GUICtrlListView_AddItem($ListView1, $Txt, $K)
           _GUICtrlListView_SetItemText($ListView1, $K, $Txt, $I)
     Next; $I
  ; Adjust ListView Column Widths
  $J = _GUICtrlListView_GetColumnCount ($ListView1)
  For $I = 0 To $J
    GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, $I, -1)
    GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, $I, -2)
  EndFunc ; PopulateListView

Any help would be much appreciated!

I do not understand what you mean "partial match" do you mean search feature ?

For fast LV display you can use @LarsJ Virtual ListView.
For finding in Recordset you can use ADO Method Find.
