Click a GUI label just after showing the GUI

Recommended Posts


Hi Forum,

I'm having trouble accomplishing the following:

I'd like to click a label on the GUI just after showing the GUI itself (to eventually fire the event bind to the label)

Here is simple version of the code (see the line under "Trying to click the 1st link")

#include <GuiConstants.au3>
#include <GuiConstantsEx.au3>
#include <SendMessage.au3>
#include <AutoItConstants.au3>

    Global $iGuiW = 400, $iGuiH = 400            ; GUI Size, Width and Height
    Global $iGuiTopH = 52, $iGuiBotH = 52        ; GUI Size, Top Height, Bottom Height
    Global $iLeftWidth = 250                    ; GUI Size, Left Menu Width
    Global $iGap = 10                            ; GUI Size, Space between links (vertical)
    Global $iRightWidth = 100
    Global $hMainGUI

    Opt('MustDeclareVars', 1)        ; Variables must be pre-declared - removes the chance for misspelled variables causing bugs
    Opt("GUIOnEventMode", 1)         ; Change to OnEvent mode
#EndRegion OPTIONS


Func _MainGui()
    ; Vars
    Local $hFooter, $nMsg, $aPos
    Local $iLinks = 5                                                                                        ; Number of links (minus 1)
    Local $sMainGuiTitle = "Main"                                                                            ; Title
    Local $sHeader = " Main - " & @ScriptName & " - " & @ComputerName                                        ; Header
    Local $sFooter = "2017©"                                                                                ; Footer
    GLobal $aLink[$iLinks], $aPanel[$iLinks], $aIdTreeviewFile[$iLinks]                                        ; Links and Panels
        $aLink[0] = $iLinks - 1
        $aPanel[0] = $iLinks - 1

    ; Shortcut to close to escape possible loop
    HotKeySet("{F1}", "OnF1")

    ; Create GUI
    $hMainGUI = GUICreate($sMainGuiTitle, $iGuiW, $iGuiH, -1, -1, BitOR($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_TABSTOP))

    ;Adding Links and bind event
    For $i = 1 To $aLink[0]
            $aLink[$i] = _AddNewLink('Link ' & $i)
            GUICtrlSetOnEvent($aLink[$i], "_ShowMessage")

    ;show the main GUI
    GUISetState(@SW_SHOW, $hMainGUI)

    ;Trying to click the 1st link
    local $hwnd = GUICtrlGetHandle ($aLink[1])
    _DebugPrint($hwnd & ' search for handle')
    local $return = _SendMessage($hwnd, $BM_CLICK)
    _DebugPrint($return & ' return from sendmessage')

    While 1
        Sleep(100) ; Sleep to reduce CPU usage

EndFunc ;==>_MainGui

Func _ShowMessage()
    MsgBox(1, '', GUICtrlRead(@GUI_CtrlId))

Func _AddNewLink($sTxt, $iIcon = -44)
    Local $hLink = GUICtrlCreateLabel($sTxt, 36, $iGuiTopH + $iGap, $iLeftWidth - 46, 17)
    GUICtrlSetCursor(-1, 0)
    GUICtrlCreateIcon("shell32.dll", $iIcon, 10, $iGuiTopH + $iGap, 16, 16)
    $iGap += 22
    Return $hLink
EndFunc ;==>_AddNewLink

Func _AddControlsToPanel($hPanel)
EndFunc ;==>_AddControlsToPanel

; to create escape function in case X is blocked.
Func OnF1()
EndFunc        ;==>OnF1

Func _DebugPrint($s_Text, $sLine = @ScriptLineNumber)
    ConsoleWrite( "DebugPrint -->Line(" & StringFormat("%04d", $sLine) & "):" & @TAB & $s_Text & @CRLF)
EndFunc   ;==>_DebugPrint

Thanks in advance!

Just use ControlClick:

;Trying to click the 1st link
    ControlClick($hMainGUI, "", $aLink[1])
    ;local $hwnd = GUICtrlGetHandle ($aLink[1])
    ;_DebugPrint($hwnd & ' search for handle')
    ;local $return = _SendMessage($hwnd, $BM_CLICK, 0)
    ;_DebugPrint($return & ' return from sendmessage')

For me that fires the  _ShowMessage function for the correct control.

Thanks Melba, that's exactly what I was searching for.

Although I swear I looked at this function before, but couldn't get it to work (must be Friday....)

Thanks again, Cheers Rick
