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)
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.
If possible please add or edit the comments to explain how this works.

Hello everybody, so I might found a bug in _ArraySearch:
#include <Array.au3> Local $abc = ["b", "b"] $h = "+---------------------------------+" & @CRLF ConsoleWrite($h) For $i = 0 To 1 $abc = 0 out() $abc = 1 out() $abc = -1 out() $abc = "Abc" out() $abc = "Hello" Next Func txt() Return "$abc = [" & $abc & ", " & $abc & "]" & @CRLF & _ "> _ArraySearch($abc,""Hello"") = " EndFunc ;==>txt Func shouldoutput($ans) Return "_ArraySearch Should return: " & ($ans ? 1 : -1) EndFunc ;==>shouldoutput Func out() ConsoleWrite("> " & txt() & _ArraySearch($abc, "Hello") & @CRLF & "> " & shouldoutput($abc == "Hello") & @CRLF & $h) EndFunc ;==>out Exit Sorry for this messy script
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").
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
