Is there an example of displaying the results in real time while entering the retrieval words?

Recommended Posts

In VB or other programming languages, fuzzy query displays database retrieval results in real time, which is easy to implement.

Taking vb as an example, the database query code is written in the Text_change event of the text box,

and the retrieval results can be displayed in real time in the Datagrid control while inputting the retrieval words.

In Au3, I don't know how to implement it.

I just know that can replace Text_change with $EN_change(As shown below),

but how to make the results of fuzzy queries display in Listview without any delay, I Has no idea. Which friend knows a similar example, or if there are any related custom functions, please give me a link?

$Form1 = GUICreate("", 533, 464)
$Input_1 = GUICtrlCreateInput("", 10, 20, 190, 20)
$Label_2 = GUICtrlCreateLabel("", 220, 30, 130, 20)

local $idlistview=GUICtrlCreateListView("aa             |bb",10,50,513,400)

Global Const $WM_COMMAND = 0x0111
GUIRegisterMsg($WM_COMMAND, "MY_WM_COMMAND")
GUISetState()
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = -3
            ExitLoop
        Case Else
            ;;;
    EndSelect
WEnd
Func MY_WM_COMMAND($hWnd, $msg, $wParam, $lParam)
    Local Const $EN_CHANGE = 0x300
    Local $nNotifyCode = BitShift($wParam, 16)
    Local $nID = BitAND($wParam, 0xFFFF)
    Local $hCtrl = $lParam
    If $nNotifyCode = $EN_CHANGE Then
        GUICtrlSetData($Label_2, GUICtrlRead($Input_1))
        GUICtrlCreateListViewItem(GUICtrlRead($Input_1), $idListview)
    EndIf
EndFunc   ;==>MY_WM_COMMAND

Depends on database.  But the general idea would be to have some sort of callback function for each row retrieved.

In SQLite for example, _SQLite_Exec is doing exactly that.

Thank you for your advice!

I just want to use editbox-listview-sqlite to implement this process.

However, I am not very familiar with the operation of listview and sqlite.

by  general method, although the process of retrieval data from sqlite and inserting listview can be realized,

there is obvious lag phenomenon, especially when the amount of data exceeds thousands, it is more obvious and even stops responding.

So want to refer to similar examples to learn, if there is a packaged UDF that is the best.

But my English is not good, can not search for similar appropriate examples.

If the response delay of the DB is long, it is also possible that the DB is not optimized for that specific query.  Using index for example could largely increase decrease (ooops) response time...

Decrease perhaps? ;)
