StungStang Posted April 10, 2011 Share Posted April 10, 2011 Im writing a search engine that have a function like "Google Instant" that shows results as you type. Now my script start when any letter is entered in the combobox and start to search... But this is not the best for performance...now i want for example do a function like that : If User Are currently Writing in ComboBox Then Do Nothing Else Start To search endiF There is a way to make it clear to the application when the user is typing the word yet? This is my currently code...But now it give me a check every second...and if i write a word that that need more than a second to write, the program equally starts searching. I hope that you have understand me...it's very unusual question. This is my current code : expandcollapse popup#include <ComboConstants.au3> #include <GUIConstantsEx.au3> #include <ListViewConstants.au3> #include <WindowsConstants.au3> #include <GuiListView.au3> #include <GUIComboBox.au3> #include <SQLite.au3> #include <SQLite.dll.au3> $hGUI = GUICreate("Let's try", 477, 191, 192, 124) $hComboBox = _GUICtrlComboBox_Create($hGUI,"", 8, 8, 145, 25) $hListView = GUICtrlCreateListView("Name|Stream|Web|Genre|State", 0, 40, 474, 150) GUISetState(@SW_SHOW) Local $fComboChange = False ; Set flag for search form GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY") GUIRegisterMsg($WM_COMMAND, "_WM_COMMAND") AdlibRegister("_Search", 200) _SQLite_Startup("YourDataBase") _SQLite_Open() While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Func _Search() If $fComboChange Then $TimerInt = TimerInit() $fComboChange = False $sText = _GUICtrlComboBox_GetEditText($hComboBox) If $sText <> "" Then _UpdateListView($sText) Else _GUICtrlListView_DeleteAllItems($hListView) EndIf EndIf EndFunc ;==>_Search Func _UpdateListView($sText) Local $aResult, $iRows, $iColumns _GUICtrlListView_BeginUpdate($hListView) _GUICtrlListView_DeleteAllItems($hListView) Local $hQuery, $aRow, $aNames $iRval = _SQLite_GetTable2d(-1, "SELECT * FROM Data WHERE Radio LIKE '%" & $sText & "%';", $aResult, $iRows, $iColumns) _ArrayDelete($aResult, 0) If $iRval = $SQLITE_OK Then _GUICtrlListView_AddArray($hListView, $aResult) _GUICtrlListView_EndUpdate($hListView) EndFunc ;==>_UpdateListView Func _WM_COMMAND($hWnd, $iMsg, $iwParam, $ilParam) $hWndFrom = $ilParam $iIDFrom = BitAND($iwParam, 0xFFFF) $iCode = BitShift($iwParam, 16) Switch $hWndFrom Case $hComboBox Switch $iCode Case $CBN_EDITCHANGE Sleep(1000) $fComboChange = True EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>_WM_COMMAND Func _WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $iwParam Local $I Global $hWndFrom, $iCode, $tNMHDR, $hWndListView, $lParam $hWndListView = $ListView $hWnd1 = $hGUI If Not IsHWnd($ListView) Then $hWndListView = GUICtrlGetHandle($ListView) $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hWndListView Switch $iCode Case $LVN_ITEMACTIVATE Local $nmia = DllStructCreate($tagNMITEMACTIVATE, $ilParam) $I = DllStructGetData($nmia, "Index") $SomeVariablex = _GUICtrlListView_GetItemTextArray($ListView, $I) ; Grab Info ;With $SomeVariablex[2] i grab the streaming link and i reproduce it with Bass.dll Global $SomeVariablex[2] EndSwitch EndSwitch Return $__LISTVIEWCONSTANT_GUI_RUNDEFMSG EndFunc ;==>_WM_NOTIFY Can be improved?

Moderators Melba23 Posted April 10, 2011 Moderators Share Posted April 10, 2011 StungStang,You are asking for a function that reads the mind of the user - not a very easy thing to do! I would suggest that rather than check every second to see if the Combo has something in it, you check periodically that it has something in it AND that the content has not changed for a time. Perhaps something like this: expandcollapse popup#include <GUIConstantsEx.au3> Global $sLast_Combo = "" Global $sUsed_Combo = "" $hGUI = GUICreate("Test", 500, 500) $hConbo = GUICtrlCreateCombo("", 10, 10, 200, 20) GUISetState() AdlibRegister("Combo_Check", 500) ; Check every half second While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Func Combo_Check() ; What is in the combo? $sCurr_Combo = GUICtrlRead($hConbo) ; Is there something? If $sCurr_Combo <> "" Then ; If it is the same as it was the last time and we have not used it If $sCurr_Combo = $sLast_Combo And $sCurr_Combo <> $sUsed_Combo Then ; Do whatever we need MsgBox(0, "Aha!", "I think you have stopped typing!" & @CRLF & @CRLF & "You typed " & $sCurr_Combo ) ; And mark this content as used $sUsed_Combo = $sCurr_Combo Else ; Otherwise save this for the next comparison $sLast_Combo = $sCurr_Combo EndIf EndIf EndFuncAll clear?

AdmiralAlkex Posted April 10, 2011 Share Posted April 10, 2011 @StungStang Change the Sleep() to a AdlibRegister("somefunction", 1000), and activate the search there, that way you search will start when the user hasn't typed anything for a second. Don't forget to AdlibUnRegister() right at the top of the adlib function. .Some of my scripts: ShiftER, Codec-Control, Resolution switcher for HTC ShiftSome of my UDFs: SDL UDF, SetDefaultDllDirectories, Converting GDI+ Bitmap/Image to SDL Surface Link to comment Share on other sites More sharing options...
