    Hi Yaron,
    you have to use either the ansi or unicode version

    Unicode and ANSI names GetWindowLongPtrW (Unicode) and GetWindowLongPtrA (ANSI)

    Same is true for Set…

    Cheers
    Claudia

      Hello again,

      I get the same error.
      No errors with Get/SetWindowLongA but the script doesn’t work. :)

      Thank you.

        Yaron

        can you do an test output to the console (preferred last line of code) and run the script at least two times. Let me check about the Set/GetWindowLongPtrW.

        Cheers
        Claudia

          Claudia,

          I had put the code in startup.py . I’ve now moved it to a separate script and run it twice.

          default

          can you do an test output to the console (preferred last line of code)

          I’m not sure what you mean.

          Aren’t you tired? Should we continue tomorrow? :)

          Thank you.

            Yaron,
            no I meant using the GetWindowLongA as I did.
            Btw. it looks like 32bit Python has to use GetWindowLong whereas 64bit Python
            uses GetWindowLongPtr.

            So make a normal script, use my code and print something to the console at the very end of the script just to see if the output is seen. If this is the case run another time and see if something changes. If so we have to change the logic about exstlye…

            Cheers
            Claudia

              It does write to the console.

              Indeed. :)

              Thank you.

                exStyle = exStyle & (~WS_EX_LAYOUTRTL)

                I’m testing it.

                Thank you.

                  Could you do me a favor and run the following script

                    Maybe XOR
                    exStyle = exStyle ^ WS_EX_LAYOUTRTL

                      Both exStyle = exStyle & (~WS_EX_LAYOUTRTL) and exStyle = exStyle ^ WS_EX_LAYOUTRTL do change the the layout.

                      I have to clear the output first. Otherwise it’s gibberish.

                      Thank you.

                        Yaron,

                        this seems to be my waterloo in terms of understanding bitwise operations.
                        I always confuse when to use OR and when XOR.

                        So, just to clarify, this works?

                        if (exStyle & WS_EX_LAYOUTRTL):
                            console.write('exStyle & WS_EX_LAYOUTRTL: {}\n'.format('exStyle & WS_EX_LAYOUTRTL'))
                            exStyle = exStyle ^ WS_EX_LAYOUTRTL
                        else:
                            console.write('exStyle | WS_EX_LAYOUTRTL:{}\n'.format(exStyle | WS_EX_LAYOUTRTL))
                            exStyle = exStyle | WS_EX_LAYOUTRTL
                        windll.user32.SetWindowLongA(python_script_sci_handle, GWL_EXSTYLE, exStyle);
                        console.write('test\n')
                        

                        Cheers
                        Claudia

                          and there seem to be a trap. The console changes it output only if something is
                          written to the output. So the initial state will be RTL until something gets written.

                          Cheers

                            If I put the code in startup.py it doesn’t work even after writing to the console.

                              Strange - works for me.
                              Could it be that you already have some ctypes based code in startup.py ?
                              Variable overwriting?
                              May you share your startup.py ?
                              Or maybe comment everything except the LTR code if you have already ctypes code.

                              Cheers

                                Do you mean the output is RTL when you open the console?

                                I’ve removed my other code for testing it.

                                Actually I don’t need it on startup. I can write a “Show Console” script.

                                Thank you.

                                  yes, on my side it is.

                                  When I run a second time from my test script it doesn’t change until
                                  another write statement happens, then it is back to LTR.

                                  Cheers

                                    Interesting.

                                    I missed that. Sorry.

                                    # The lines up to and including sys.stderr should always come first
                                    # Then any errors that occur later get reported to the console

                                      When I run a second time from my test script it doesn’t change until
                                      another write statement happens, then it is back to LTR.

                                      On my machine it changes immediately. It’s gibberish until writing again.

                                      Thanks.

                                        Yaron,

                                        strange - might be linux/windows related.
                                        I’ve copied your startup.py - cleaned mine (commented everything)
                                        and now I have your behavior. Phew …

                                        Yaron, it is already half past 4 here and I have to go to late shift today.
                                        Need to have some sleep ;-) I will follow up on this in ~16 hours.
                                        Maybe earlier if we don’t have to do much at work and I can have look.

                                        Good night.
                                        Cheers
                                        Claudia
