Inconsistencies in ControlGetText from some windows

2 posts in this topic

Hello all! I have had some issues reading text from different types of windows, occasionally, specifically with controlgettext. 

**Before I begin, I know there are better ways to do what I attempt in the example below. That's not the point of this post. The point is my issues with controlgettext. 

I am about to cite an example with an application you may be familiar with called SpeedFan (v4.52). My problem is not specific to speedfan, it is simply the most recent and easily reproducible example I can think of. 

So, the goal of the script below is to get a string of text containing the current fan RPMs from the highlighted control in the screenshot below (see "speedfan_control_details.png").

speedfan_control_details.png

Now, here's a simple script for grabbing the window handle and reading the text from that control: 

$wintitle = "SpeedFan 4.52"
$controlID = "197934" ;will be reformatted as "[ID:######]"

$hwnd = wingethandle($wintitle)
if @error<>0 then
    msgbox(0, "WinGetHandle", "FAILURE. @error="&@error)
    Exit
EndIf

$text = ControlGetText($hwnd, "", "[ID:"&$controlID&"]")
if @error=1 then
    msgbox(0, "ControlGetText", "FAILURE. @error="&@error) ;failure returns "" and @error=1
    Exit
EndIf

msgbox (0, "ControlGetText", "SUCCESS. @error="&@error &@CRLF& "$text="&$text) ;success returns string and @error=0

You'll see that the ControlGetText operation runs without error, however it does not capture any text from the control. If you explore the other controls in this one window, you'll find mixed results across the board. Neither the temps nor voltages can be read, while the log field and some other elements can be read. Even when you read the text from the whole window, those elements are not included in the visible nor hidden texts. 

 

I have run into this issue many times in the past- inconsistencies in the ability of autoit to interact with certain controls. What is it which makes this text different than any other readable texts? Is there an alternate method of reading the text in the window/control which could work? Any and all info to help me solve this mystery and satisfy my curiosity would be greatly appreciated. 

Thanks :) -Rob C

I don't think this will be the case in this instance, but sometimes control groups are selected above the actual controls within the groups by the spy tool.  Try using my signature function to get all controls within a window, and see if you have any luck.  The function expects a handle from wingethandle

      Hello.
      I'm too stupid to see my mistake:
      To investigate the internal "dictionary" of TIFF files I'd like to read in the files in binary mode and to check, if there are more than one pages "in" this TIFF.
      Notepad++, "View as Hex" is presenting the first bytes as "49 49 2a 20 08 20 20 20 12" for the TIF attached to this posting
      The "TIFF Header Format" is easy:
      Offset 00h, 2 Byte = Byte Order, "II"=intel, "MM"=motorola. (I = 0x49)
      --> II
      Offset 02h, 2 Byte = Version Nr.
      Offset 04h, 4 Byte = pointer to first IFD entry
      Description of TIFF header: https://www.awaresystems.be/imaging/tiff/faq.html#q3
       

      Howto read and analyse the binary content correctly? This is my messy, not operational code:
       
      $sampleTiff="H:\daten\tif\11\11\111111.TIF" $h=FileOpen($sampleTiff,16) $content=FileRead($h) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $content = ' & $content & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console FileClose($h) $type=VarGetType($content) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $type = ' & $type & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $ToString=BinaryToString($content) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $ToString = ' & $ToString & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ConsoleWrite(@CRLF & @CRLF) $content=StringTrimLeft($content,2) ; cut off the leading "0x" ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $content = ' & $content & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console for $i = 1 to 8 step 8 $next=StringMid($content,$i,2) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $next = ' & $next & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $Chr=BinaryToString($next) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $Chr = ' & $Chr & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ConsoleWrite(@CRLF & "---" & @CRLF) Next Regards, Rudi.

      I have previously used _IEFormElementGetObjByName and _IEFormElementSetValue to enter text into a search box on a form and then submit the form.
      I am now trying to enter text into a search box which is not part of a form. 
      Here is the HTML from the website that i'm trying to enter the data on and then submit the search.
      <div class="row">
          <div class="form-group col-xs-12">
              <span id="FullWidthWithSubmenuContent_FullWidthContent_MainContent_AircraftRegistry_lblSearchText" for="input-search">Registreringsbeteckning</span>
              <div class="input-group col-xs-12">
                  <span id="FullWidthWithSubmenuContent_FullWidthContent_MainContent_AircraftRegistry_preSearchText" class="input-group-addon">SE -</span>
                  <input name="ctl00$FullWidthWithSubmenuContent$FullWidthContent$MainContent$AircraftRegistry$txtSearchText" type="text" value="DTH" id="FullWidthWithSubmenuContent_FullWidthContent_MainContent_AircraftRegistry_txtSearchText" class="form-control" />
              </div>
          </div>
      </div>
      <div class="row">
          <div class="form-group col-xs-12">
              <label class="sr-only" for="">Sök</label>
              <input type="submit" name="ctl00$FullWidthWithSubmenuContent$FullWidthContent$MainContent$AircraftRegistry$btnSearch" value="Sök" id="FullWidthWithSubmenuContent_FullWidthContent_MainContent_AircraftRegistry_btnSearch" class="btn btn-primary ladda-button" data-style="expand-right" />
          </div>
      </div>
      Many thanks in advance
      cheers

      Hello Forum,
      I'm trying to vertically center text in label controls, but no way. The search on the forum returns no result, or I don't search the right way
      When I insert a button and a label of same size close to each other, the text is centered on the button, but top aligned on the label, or edit. Which doesn't look really aesthetic
      Any idea is welcome
      Thanks in advance,
      Thoms

      Hi Guys, 
      So with me working in my Virtual Machines in full screen, I often have my Host OS playing music. Now the issue I had was trying to control the Host OS without having to minimise the Guest OS.
      So I thought of this small program. I call it the Volume Control. It resides in the bottom right hand corner of your screen just above the system clock. 
      I'm still working on getting the volume buttons to increase/decrease when you hold down the button.
      Currently, you will need to tap on the volume buttons numerous times to decrease/increase the volume. 
      Any other improvements let me know. 
      The source code, icon and compiled program are already in the zip.

      Hello guys
      Today I'll give you three functions to manage the list View items
      These functions will help you to do some works in your list view items
      1. list view Read
      To get the selected item text  
      2. listView_checke
      To checke an item
      3. isListViewChecked
      To see if the item is checked
      All of these functions will be illustrated by the following example
      You can download the include file from the link below
      Now with the example
      #include <easy_listView_functions.au3> #include <GUIConstantsEx.au3> #include <GuiListView.au3> #include <MsgBoxConstants.au3> Example() Func Example()  Local $idListview  GUICreate("ListView Get Item Checked State", 1000, 700)  $idListview = GUICtrlCreateListView("", 50, 30, 250, 120, 50)  _GUICtrlListView_SetExtendedListViewStyle($idListview, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_CHECKBOXES)) ; Add items $item1 = GUICtrlCreateListViewItem("item1", $idListview) $item2 = GUICtrlCreateListViewItem("item2", $idListview) _listview_Checke($idListview, "item1") $btn = GUICtrlCreateButton("&read", 100, 150, 50, 50) $btn2 = GUICtrlCreateButton("&if checked", 100, 200, 100, 50)  GUISetState(@SW_SHOW) while 1 switch GUIGetMSG() case $GUI_EVENT_CLOSE  GUIDelete() exit case $btn $read = _ListView_read($idListView) if $read then msgBox(0, "read listview", $read) else msgBox(0, "read listview", "no text ditected") endIf case $btn2 if _isListviewChecked($idListView, "item1") then msgBox(0, "get", "the item is checked") else msgBox(0, "get", "the item isn't checked") endIf endSwitch wend EndFunc   ;==>Example
