Ok, I don't know if this is even possible but some help would be greatly appreciated. I've been googling like crazy and trying different things but i'm just not getting anywhere.

I'm trying to control an arduino from an Autoit script ... over the web. I have a script that is working and i have serial communication figured out. currently the script is simple and turns a couple of relays on and off. what i'd like now is to do this from a webpage. ideally a gui interface like the one i have now would be great but i've also tried using cgi to launch a script that turns on a relay (so two links one to run a script to turn on and one to turn off) but after the script runs i get an error page. I'd like to set it up where if i can't have the gui then i can click the link run the script but stay on the same page. I hope all of this is making sense.

Here is a copy of the gui script that is working:

I'm sorry you haven't had a reply to this, and I understand things up to where you said "over the web".  Anyway, had you realised that each time you make contact with the Arduino's com port it resets the Arduino? There's a good explanation of that  is your first script holding the port, so the 2nd fails?

Ok, the script is running as written.  It launches a gui and I have an On and an Off for each relay.  If I run the script on the "web server" that has the arduino connected to it locally everything works fine.  I can turn the relays on and off without any issues. Now i need for that "gui" to run in my webpage and i'll mainly be using it locally in the house for home automation but if i can get working well internally i'll open the ports up and control things remotely.  I also have found some info on using CGI but i don't have a good understanding of it so if anyone could help with that even though this isn't that kind of forum.  I'm open to all and any suggestions.

Thanks

      I am making some GUI with combobox for the Baudrates communications and I listed 9600, 57600, 115200. 
      I wrote the code to be defaulted to 57600 like this:
      GUICtrlSetData($comboBox_opticalBaudRate, "9600|57600|115200", "57600")
      But I wanted the GUI to remember the last item the user picks so the baudrates will NOT be defaulted to 57600.
      Example, I pick 9600 as my baudrates, then I close the GUI, after opening it, it always prompt 57600 since that is what I did in my code. But I want that if I choose 9600 and close the GUI, opening it again will show 9600 now instead of 57600.
      Is there a way to do it in GUI setting?
       
      Thanks.

      Hi,
      I am having a problem properly saving the Width of a resizable Gui.
      When a user resizes the Gui it gets saved in an ini when the Gui closes to then restore the new Width upon reopening the app.
      with GUICreate("myGui",300,200,Default,Default,$WS_SIZEBOX)
      WinGetPos($hGUI) returns 314, and WinGetClientSize($hGUI) returns 298
      when its then saved in the ini the gui keeps expanding or shrinking every time its opened by +14 or -2
      I figure it has to do with borders etc, but i also guess borders depend on the window theme and whatnot or is user specific, so i can't just do $GuiWidth = $GetGuiWidth[arr] -14 or +2 right?

      is there a proper way of doing this?
      Thanks in advance,

      I have provided a portion of my script (seen below) and I wanted to use what the USER will input into my IP address box and input box for TCP port. I set the IP address to use 0.0.0.0 as default and the Port to 502. But I want to let the user change it and when they click the buttons (IP Address and Port), the tooltip will show what the USER entered. How can I use the details that the User will input into my input box and IP address box and let them see what they entered when they click the buttons?

      So I am a person who has learned programming off the internet, without structured courses, and I'm trying to create a UI element that can be used like "GUICtrlCreate...".

      I'd like to get some kind of insight on how to improve the code of a Graph element that I have created.
      I am unfamiliar on the standards for creating such UI elements, and assume I'll get some valuable insight here.
       
      Here's some sample code: (I tried to make it look a bit less upsetting to those who know better, but be warned: not pretty.)
      #include <WinAPISys.au3> #include <WinAPI.au3> #include <WinAPIGdi.au3> #include <Array.au3> #include <WindowsConstants.au3> #include <GUIConstants.au3> Local $hWnd = GUICreate("Test", 200, 200) GUISetState(@SW_SHOW, $hWnd) Local $hGraph = _GraphStartUp($hWnd, 10, 30, 180, 180) Local $nData, $nDataMax = 1000, $hDataTimer = TimerInit() While GUIGetMsg() <> $GUI_EVENT_ClOSE If TimerDiff($hDataTimer) >= 150 Then $nData = Random(0, $nDataMax) _UpdateGraph($nData) $hDataTimer = TimerInit() EndIf Sleep(20) WEnd _GraphShutDown($hWnd, $hGraph) Exit Func _GraphStartUp($hWnd, $x, $y, $w, $h, $nUpdateTimes = 1000, $nResolution = 60) Global $hBluePen = _WinAPI_CreatePen($PS_SOLID, 2, _WinAPI_RGB(220, 0, 0)) Global $hGreyPen = _WinAPI_CreatePen($PS_DASH, 1, _WinAPI_RGB(100, 100, 100)) Global $hBlackPen = _WinAPI_CreatePen($PS_SOLID, 1, _WinAPI_RGB(0, 0, 0)) Global $hWhitePen = _WinAPI_CreatePen($PS_SOLID, 1, _WinAPI_RGB(255, 255, 255)) Global $nGraphRes = $nResolution Global $aGraphData[$nGraphRes + 1] For $i = 2 To $nGraphRes $aGraphData[$i] = 0 Next Global $hWinDC = _WinAPI_GetWindowDC($hWnd) Global $nGraphX = $x Global $nGraphY = $y Global $nGraphWidth = $w Global $nGraphHeight = $h Global $nGraphXUnit = $nGraphWidth / ($nGraphRes - 1) Global $nGraphBottomY = $nGraphY + $nGraphHeight Global $nGraphMaxX = $nGraphX + $nGraphWidth Global $aUpdateArea[4][2] = [[$nGraphX - 1, $nGraphY - 1], [$nGraphX - 1, $nGraphBottomY + 1], [$nGraphMaxX + 1, $nGraphBottomY + 1], [$nGraphMaxX + 1, $nGraphY - 1]] Global $pUpdateAreaRgn = _WinAPI_CreatePolygonRgn($aUpdateArea) Global $pTextRect = _WinAPI_CreateRectEx($nGraphX + 1, $nGraphY + 1, $nGraphWidth / 2, $nGraphHeight / 4) Global $nGreatestValue = 1 GLobal $pGraphArea = _WinAPI_CreateRectEx($nGraphX - 7, $nGraphY - 26, $nGraphWidth + 14, $nGraphHeight + 2) Global $pDrawCall = DllCallbackRegister('_DrawGraph', 'none', '') Global $pGraphTimer = _WinAPI_SetTimer($hWnd, 567891234, $nUpdateTimes, DllCallbackGetPtr($pDrawCall)) _DrawGraph() Return $pGraphTimer EndFunc Func _DrawGraph() Global $hPen $nGreatestValue = _ArrayMax($aGraphData, 1, 1) $hPen = _WinAPI_SelectObject($hWinDC, $hWhitePen) _WinAPI_PaintRgn($hWinDC, $pUpdateAreaRgn) $hPen = _WinAPI_SelectObject($hWinDC, $hGreyPen) _WinAPI_DrawLine($hWinDC, $nGraphX, $nGraphY, $nGraphMaxX, $nGraphY) _WinAPI_DrawLine($hWinDC, $nGraphX, $nGraphY + ($nGraphHeight / 2), $nGraphMaxX, $nGraphY + ($nGraphHeight / 2)) _WinAPI_DrawLine($hWinDC, $nGraphMaxX, $nGraphY, $nGraphMaxX, $nGraphBottomY) $hPen = _WinAPI_SelectObject($hWinDC, $hBluePen) For $i = 1 To $nGraphRes - 1 _WinAPI_DrawLine($hWinDC, $nGraphX + (($i - 1) * $nGraphXUnit), $nGraphBottomY - ($aGraphData[$i] / $nGreatestValue * $nGraphHeight), $nGraphX + ($i * $nGraphXUnit), $nGraphBottomY - ($aGraphData[$i + 1] / $nGreatestValue * $nGraphHeight)) Next $hPen = _WinAPI_SelectObject($hWinDC, $hBlackPen) _WinAPI_DrawLine($hWinDC, $nGraphX, $nGraphBottomY, $nGraphMaxX, $nGraphBottomY) _WinAPI_DrawLine($hWinDC, $nGraphX, $nGraphY, $nGraphX, $nGraphBottomY) _WinAPI_DrawText($hWinDC, Round($aGraphData[$nGraphRes], 2), $pTextRect, $DT_LEFT) EndFunc Func _UpdateGraph($nData) _ArrayAdd($aGraphData, $nData) _ArrayDelete($aGraphData, 1) EndFunc Func _GraphShutDown($hWnd, $pGraphTimer) _WinAPI_SelectObject($hWinDC, $hPen) _WinAPI_DeleteObject($hBlackPen) _WinAPI_DeleteObject($hGreyPen) _WinAPI_DeleteObject($hBluePen) _WinAPI_DeleteObject($hWhitePen) _WinAPI_ReleaseDC($hWnd, $hWinDC) _WinAPI_KillTimer($hWnd, $pGraphTimer) DllCallbackFree($pDrawCall) _WinAPI_RedrawWindow($hWnd, $pGraphArea) EndFunc
