How can a guictrlsetonevent function stop working sometimes??

3 posts in this topic

#1 ·  Posted (edited)

Hi, I'm totally stumped by this one. I have a general purpose input function that allows a user to select one of a group of radio buttons. As soon as a radio is clicked the gui deletes and returns the text of the choice to the calling function.

It works really nicely but i have two functions that call it and the event function for selecting a button never runs, it just gets stuck in the loop waiting for a response.

It still works in all other cases (in the same execution of the program). And cutting and pasting (to check for typos etc) the call and the function to a test file (not connected to the rest of the code) it works.

Is there anything that can stop an event function being called?

the function is:

~ ;takes possible choices separated by | in a string, returns the chosen answer or "input cancelled" if closed

Func RadioQBox($title, $prompt, $choices)

Local $c = StringSplit($choices, "|");make array into string

Local $rads[$c[0] + 1] = [$c[0]];array for control ids

Local $ypos = 50, $msg, $sel;set y postion

Local $hgt = ($c[0] * 40) + 100;set height

GUISetState(@SW_DISABLE, $siteGui);disable main gui

Local $radGui = GUICreate($title, 500, $hgt, -1, -1, BitOR($WS_CAPTION, $WS_POPUP, $WS_SYSMENU), $WS_EX_TOPMOST);build form

GUICtrlCreateGroup($prompt, 50, 10, 400, $hgt - 10)

For $i = 1 To $c[0];create radios

$rads[$i] = GUICtrlCreateRadio($c[$i], 60, $ypos, 380, 15)

GUICtrlSetOnEvent($rads[$i], "RadioChoice");set on event function

$ypos = $ypos + 40



Global $RadChoice = 0;selected flag

While Not $RadChoice




;db("Radiochoice answer")

For $i = 1 To $c[0]

If $RadChoice = $rads[$i] Then

$sel = $c[$i]

$RadChoice = 0


If $sel = 'other' Then

db("Radiochoice other")

$sel = InputBox($title, $prompt & @CRLF & "It is recommended that you make your answer roughly the same length and format as the other options")




GUISetState(@SW_ENABLE, $siteGui)

Return $sel

EndFunc ;==>RadioQBox

The event is

Func RadioChoice()

$RadChoice = @GUI_CtrlId

;db("radiochoice event", @GUI_CtrlId, @GUI_WinHandle, @GUI_CtrlHandle)

EndFunc ;==>RadioChoice

Hope you can help

Sorry about the format in the previous post :oops:

Ok i think i have found the problem. Apparently the event function has to complete before another event can be registered.

I can fix this by having the event just set flags that are picked up in the main loop but it is making things a bit slow.

Is there a way to clear the event so another one can take place before the function ends?

Any suggestions would be greatly appreciated.

      Tell me, please, why in the application of different styles($SS_BLACKFRAME, $SS_BLACKRECT, etc.) of frames stops working function Msg().
      And why in the application of certain frame styles($SS_BLACKFRAME) do not even picture displayed?
      #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <StaticConstants.au3> Opt("GUIOnEventMode", 1) Example() Func Example() GUICreate("My GUI picture", 350, 300, -1, -1) ; will create a dialog box that when displayed is centered GUISetOnEvent($GUI_EVENT_CLOSE,"Quit") $idPic = GUICtrlCreatePic("D:\Program Files\AutoIt3\Examples\GUI\mslogo.jpg", 50, 50, 200, 50, $SS_SUNKEN) GUICtrlSetOnEvent(-1,"Msg") GUISetState(@SW_SHOW) ; Loop until the user exits.

      Inspired from

      I created a UDF that I have been using to replace GUICtrlSetOnEvent, not using Opt("GUIOnEventMode").
      AutoIt's GUICtrlSetOnEvent function only supports mouse clicks without parameters at this moment, this UDF works on the same premise but gives the user some more flexibility, in just 61 lines of code.
      Here is an example of what A callback will look like
      Func MyCallBackFunction(Const $wParam, ByRef $iCtrlId, ByRef $uData, ByRef $hWnd) Switch $wParam Case $WM_HOVERIN ConsoleWrite("Entering control; attached data = " & $uData & @CRLF) Case $WM_HOVEROUT ConsoleWrite("Leaving control" & @CRLF) Case $WM_LBUTTONDOWN ConsoleWrite("Left mousebutton DOWN" & @CRLF) Case $WM_LBUTTONUP ConsoleWrite("Left mousebutton UP" & @CRLF) Case $WM_MBUTTONDOWN ConsoleWrite("Middle mousebutton DOWN" & @CRLF) Case $WM_MBUTTONUP ConsoleWrite("Middle mousebutton UP" & @CRLF) Case $WM_RBUTTONDOWN ConsoleWrite("Right mousebutton DOWN" & @CRLF) Case $WM_RBUTTONUP ConsoleWrite("Right mousebutton UP" & @CRLF) EndSwitch EndFunc  
      More examples can be found in the zip file.
      Good 2 know
      GuiDelete($hWnd) used together with $WM_LBUTTONUP will cause the AutoIt script to crash $WM_HOVERIN and $WM_HOVEROUT ARE NOT real Windows Message codes and will only work with with this UDF Your callback functions MUST have 4 parameters assigned to it. That's about it.
      Feel free to pitch some improvements.

      here I am writing simple gui with text processing capabilities.
      i have main gui, background picture, all buttons with labels over them 2 static buttons (1 present here)
      Opt("GUIOnEventMode", 1) and includes
      $main = GUICreate("Title", 961, 721); Main Window $bgpic = GUICtrlCreatePic(@WorkingDir & "\960x720.jpg", 0, 0, 960, 720); use background picture $quitBtn = GUICtrlCreateButton("Quit", 885, 685, 95, 40) GUICtrlSetOnEvent($quitBtn, "_exit"); assign quit button to function "exit" _GuiCtrlMakeTrans(-1, 1) $quitLabel = GUICtrlCreateLabel("Quit", 885, 685, 95, 40, BitOR($SS_CENTER, $BS_BOTTOM)) GUICtrlSetFont(-1, 14, 400, 0, "Tahoma") GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT) GUICtrlSetColor(-1, 0x962129) GUISetState(@SW_SHOW)
      then i have the code for creating buttons dynamically from information in file
      Dim $Button[$NumberFromText] $startX = 48 $startY = 24 $fromLeft = 240 $bHeigh = 160 $bWidth = 50 Dim $1to4btn[0] For $x = 0 To _Min(UBound($Button) - 1, 3) ; creates maximum 4 button, label $Button = GUICtrlCreateButton($x, $startX, $startY, $bHeigh, $bWidth); create buttons _GuiCtrlMakeTrans(-1, 1) ; transparency 255 Solid, 0 Transparent $serverLabel = GUICtrlCreateLabel(FileReadLine($configF, $SN), _ ; read 1st line and 5 below on each iteration $startX, $startY, $bHeigh, $bWidth, BitOR($SS_CENTER, $SS_CENTERIMAGE, $WS_EX_TRANSPARENT)); GUICtrlSetFont(-1, 14, 400, 0, "Tahoma"); set font and size GUICtrlSetColor($serverLabel, 0x04A111); set color of font GUICtrlSetBkColor($serverLabel, $GUI_BKCOLOR_TRANSPARENT); make label Background transparent $SN += 5; read 5 lines below $startX = $startX + $fromLeft $btnArray=_ArrayAdd($1to4btn, GUICtrlGetHandle($Button)) Next since buttons are created under the label $Button and I couldn't conacenate $Button[$i] , I created array and place handles into it and connected static buttons with
      GUICtrlSetOnEvent($cancelBtn,"cancelFunc") and it worked
      now i tried using handles to assign functions to buttons but it fails with GUICtrlSetOnEvent()
      also tried GUISetOnEvent($GUI_EVENT_PRIMARYDOWN, "funcForFirstButton", $1to4btn[0])
      if I assign without handle it works by clicking anywhere on MainGUI
      While loop includes only sleep(10)
      Window starts as inactive and return code 7
      If i click dynamically created buttons, window loses focus . clicking anywhere else focuses window
      this is _GuiCtrlMakeTrans function (found here on forums some time ago)
      also created simple button on the same mainGUI and tried but didn't work
      $try=GUICtrlCreateButton("TRY",250,150,100,35) GUICtrlSetOnEvent(-1,"FunctionOne") ; shows messagebox and write console

      I am working on a script that pulls the current time from the internet and then reads contents from our backup server based on the month and week folders that are already created. This script will ultimate pass variables to another program that will restore the data from the respective folder to the computer that the script it running on. The script is built to find the 'windows' folders in the server structure which is \\server\serverfolder\01_16\3week
      \\server\serverfolder - is the server share
      01_16 - is month and year as to sort properly
      3week - is obviously the week
      Within the week folder there are user folders (eg. bsmith, jdoe, ganderson), in these folders are backups of full hard drives with include the windows folder which we are looking for.The script is running and is fully function the first time that it is run. I have also added a back button so if for some reason you are in the wrong list of folders you can navigate to the correct folder and then show the results again.
      The issue I am having is that I can show the contents and everything works well, unless I use the back button and navigate to a different set of folders (different week). The radio buttons do not respond properly. They will show both incorrect data and the count of radio buttons is not being updated.
      I have attempted to look for a solution and have tried many different ideas, but I just don't fully understand how a GUICtrlCreateRadio in a for loop with GUICtrlSetOnEvent should work.
      Any suggestions would be greatly appreciated. I apologize for the messy code.

      need little help from the expert, I don't know whats wrong with my script, only one button is working, button6.
