I am unsure what the other "blocking functions" are, but I am not calling MsgBox or OpenFilewhatever at the time I am using the hotkeys. Here is some sample code, it will not compile but gives you an idea of what I'm doing:

global $_paused
HotKeySet("{PAUSE}", "togglePause")
HotKeySet("{ESC}", "exitScript")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            _ExitScript()
        Case $GUI_EVENT_PRIMARYDOWN
            $aMouseInfo = GUIGetCursorInfo($hChildGUI)
            if (@error = 0) AND ($aMouseInfo[4] <> 0) AND StringinStr($sNoClickList,"|" & $aMouseInfo[4] & "|") = 0 then
                if $hFocusedCell <> "" then
                    GUICtrlSetBkColor($hFocusedCell,0xFFFFFF)
                    GUICtrlSetData($hFocusedCell,GUICtrlRead($hEdit))
                ;endif
                    $hFocusedCell = ""
                    GUICtrlSetData ($hEdit,"")
                endif
            ;if (@error = 0) AND ($aMouseInfo[4] <> 0) then
                $hFocusedCell = $aMouseInfo[4]
                GUICtrlSetBkColor($aMouseInfo[4],0x00CCFF)
                GUICtrlSetData($hEdit,GUICtrlRead($hFocusedCell))
            endif
        Case $hFileExit
            _ExitScript()
        Case $hFileOpen
            _UpdateSplash($hStatus,"Please open spreadsheet")
            $oSheetData = _OpenExcel(1)
            if $oSheetData <> 0 then 
                _CreateArray($oSheetData) ;should fill out array here
                _DrawChildGUI(_Min(UBound($xlsArray,2) - 1,40),UBound($xlsArray,1) - 1) ;i should possibly pass array instead of size of array
            endif
        Case $hFilePref
            _DrawPrefGUI()
        Case $hRunButton
            if _ValidateHeaders() then
                _JavaAttachAndWait("Oracle Applications - ")
                global $_winPos = _OracleOpen("Purchasing Buyer","Purchase Order Summary")
                _ProcessPOs()
                _UpdateSplash($hStatus,"End of spreadsheet reached")
            endif
    EndSwitch
    if _IsPressed("25",$hUser32Dll) AND $hFocusedCell <> "" AND BitAnd(WinGetState("hChildGUI"),8) then _SelectCell(0,-1);LEFTARROW
    if _IsPressed("26",$hUser32Dll) AND $hFocusedCell <> "" AND BitAnd(WinGetState("hChildGUI"),8) then _SelectCell(-1,0) ;UPARROW
    if _IsPressed("27",$hUser32Dll) AND $hFocusedCell <> "" AND BitAnd(WinGetState("hChildGUI"),8) then _SelectCell(0,1) ;RIGHTARROW
    if _IsPressed("28",$hUser32Dll) AND $hFocusedCell <> "" AND BitAnd(WinGetState("hChildGUI"),8) then _SelectCell(1,0) ;DOWNARROW
    if _IsPressed("0D",$hUser32Dll) AND $hFocusedCell <> "" then _SelectCell(1,0,1) ;ENTER
    if _IsPressed("09",$hUser32Dll) AND $hFocusedCell <> "" then _SelectCell(0,1,1) ;TAB
WEnd

func _ExitScript()
    if isObj($oExcel) then
        $oExcel.DisplayAlerts = True
        $oExcel.Quit
    endif
    DllClose($hUser32Dll)
    exit
endfunc

func _TogglePause()
    $_paused = NOT $_paused
    while $_paused      
sleep(100)
    wend
endfunc

i realize this may not be enough to troubleshoot, but basically the hotkeys work while in the GUI loop, but not once i press Run Script button. The functions called in that section do not utilize anything out of the ordinary that didn't prevent me from being able to pause in previous scripts. I can show you the functiosn it calls, but it is basically just a series of java access bridge functions and sends and whatnot. stuff that previously i was able to interrupt when I did not stick it in a GUI. Any idea whats going on?

Thanks!

Hi, I have done more research, as I probably should have before, and it appears it is anytime it answers a GUI message via GUIGetMsg() that it ceases to accept Hotkeys. If I try and execute the hotkeys before triggering one of the GUI events, it works. But once I have triggered a GUI event, it ceases to work. Here is a simplified version of what doesn't work that should compile.

Thanks

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

global $_paused = 0
global $iH_MainSize, $iV_MainSize, $iH_MainPos, $iV_MainPos
global $hFileMenu, $hViewMenu
global $hMainGUI, $hChildGUI

$iH_MainSize = 800
$iV_MainSize = 600
$iH_MainPos = 50
$iV_MainPos = 20

HotKeySet("{PAUSE}", "togglePause")
HotKeySet("{ESC}", "exitScript")

$hMainGUI = GUICreate("test", $iH_MainSize, $iV_MainSize, $iH_MainPos, $iV_MainPos)
$hFileMenu = GUICtrlCreateMenu("File")
$hFileExit = GUICtrlCreateMenuItem("Exit", $hFileMenu)
$hRunButton = GUICtrlCreateButton("Run Script",600, 3, 150, 22)
GUISetState(@SW_SHOW, $hMainGUI)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            _ExitScript()
        Case $GUI_EVENT_PRIMARYDOWN
        Case $hFileExit
            _ExitScript()
        Case $hRunButton
            while 1
                sleep(100)
            wend
    EndSwitch
WEnd

func _ExitScript()
    exit
endfunc

func _TogglePause()
    $_paused = NOT $_paused
    while $_paused
        sleep(100)
    wend
endfunc

So if you press ESC or PAUSE after loading the GUI (while in the GUI loop), it works. Once you you press the Run Script button, the hotkeys no longer work. I hope this is now simple enough for someone to be able to answer. Thanks!

Well, you typo'd your function names, but with that corrected: 

HotKeySet("{PAUSE}", "_TogglePause")
HotKeySet("{ESC}", "_ExitScript")

What did you expect it to do? Both the "{PAUSE}" and "{ESC}" hot keys work fine. You can't tell with the "{PAUSE}" function because there isn't anything being done to see paused or not.

Once you hit the "Run Script" button, no more GUIGetMsg() processing happens because it's trapped in a While/WEnd loop with no exit. But the hot keys still work even then.

jeffml,

As explained in the Interrupting a running function tutorial in the Wiki, HotKeys are one of the few ways to break into a running function, so I am more than a little surprised that you say they do not work. ;)

If I change the HotKey declarations to match the actual function names, the HotKeys work with out problem - as this script with a few added MsgBoxes should show (it works fine for me): :)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $_paused = 0
Global $iH_MainSize, $iV_MainSize, $iH_MainPos, $iV_MainPos
Global $hFileMenu, $hViewMenu
Global $hMainGUI, $hChildGUI

$iH_MainSize = 800
$iV_MainSize = 600
$iH_MainPos = 50
$iV_MainPos = 20

HotKeySet("{PAUSE}", "_togglePause")
HotKeySet("{ESC}", "_exitScript")

$hMainGUI = GUICreate("test", $iH_MainSize, $iV_MainSize, $iH_MainPos, $iV_MainPos)
$hFileMenu = GUICtrlCreateMenu("File")
$hFileExit = GUICtrlCreateMenuItem("Exit", $hFileMenu)
$hRunButton = GUICtrlCreateButton("Run Script", 600, 3, 150, 22)
GUISetState(@SW_SHOW, $hMainGUI)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            _ExitScript()
        Case $GUI_EVENT_PRIMARYDOWN
        Case $hFileExit
            _ExitScript()
        Case $hRunButton
            MsgBox(0, "", "Running!")
            While 1
                Sleep(100)
            WEnd
    EndSwitch
WEnd

Func _ExitScript()
    Exit
EndFunc   ;==>_ExitScript

Func _TogglePause()
    $_paused = Not $_paused
    If $_paused Then
        MsgBox(0, "", "Paused!")
    Else
        MsgBox(0, "", "Not Paused!")
    EndIf
    While $_paused
        Sleep(100)
    WEnd
EndFunc   ;==>_TogglePause

Of course, as explained in the tutorial, none of the other GUI controls (such as the [X]) will work. :shocked:

Do you still have the same problem when running this script? ;)

OMG!

I am so sorry for wasting anyone's time I just realized what it was. i renamed the exitScript and togglePause functions to _ExitScript and _TogglePause, but didnt change that in the hotkey commands. I cannot believe I made such an oversight, I'm sorry!

Haha, yes thank you. I just realized that myself.
