      What if the user has multiple windows open with the same title? Multiple unsaved models etc?

      I know, that's why I don't want to use it and want my first code to work!

        You experienced crashes?

        Yes, and it seems to have something to do with toolbars from 3rd party. When I have all of them visible (about 30 of them), your code runs for about 10 secs then SK unload from memory!

          From Ruby you can get process id, like:
          $$
          or
          Process.pid

          I'm not here much anymore.

            That worked 👍 I should have used GetCurrentProcessId instead of GetCurrentThreadId 😒 but your way is much simpler. Thanks!

              Using "Untitled" as a substring only works in English editions.

              In other editions it's bound to be a unicode string.

              The Win32 Resource ID in the sketchup.exe String Table is 61443 (in case you like using a LoadString system call.)

                True!

                But I don't think my approach or that of thomthom to get the SKP window works. If you use Process.pid and enum the windows until you find the right one, and use GetWindowText WinAPI to get the title of the SKP window, it works, but not always. I have a shortcut to SKP in one of my folder and it works to get the title, but if I use the Windows Start menu to run SKP, the title is blank, so it's not getting the proper window as expected. And since the return text is blank, we can't tell which window it is!

                So try it using the following...

                wnd = getAncestor.call(wnd, 3)
                buf = "\0" * 260
                getWindowText.call(wnd, buf, 256)
                UI.messagebox(buf.strip)
                
                

                or the complete code...

                getTopWindow = Win32API.new('user32.dll', 'GetTopWindow', 'l', 'l')
                getWindow = Win32API.new('user32.dll', 'GetWindow', 'li', 'l')
                getWindowThreadProcessId = Win32API.new('user32.dll', 'GetWindowThreadProcessId', 'lp', 'l')
                getWindowText = Win32API.new('user32', 'GetWindowText', 'LPI', 'I')
                getAncestor = Win32API.new('user32', 'GetAncestor', 'LI', 'L')
                
                tid = Process.pid
                wnd = getTopWindow.call(0)
                pid = 0.chr * 4
                while wnd != 0
                   getWindowThreadProcessId.call(wnd, pid)
                   pidnum = pid.unpack('L').first
                   if pidnum == tid
                			wnd = getAncestor.call(wnd, 3)
                			buf = "\0" * 260
                			getWindowText.call(wnd, buf, 256)
                			UI.messagebox(buf.strip)
                      break
                   end
                   wnd = getWindow.call(wnd, 2)
                end

                  I found the answer to my own problem! I was running the code inside my class

                  I don't know why it makes a difference!

                    You should always be running your wrapped within a module.

                    The problem with TopWindow is that if a user has wxSU installed, the Sketchup window will be wrapped in a WX::Frame, and wxSU resets the Sketchup app window to have the invisible frame as it's parent.

                    There are other quirky title things. If a user double clicks a SKP file to start Sketchup, the Title will not have "Untitled" (in the local language,) but could have a filename with unicode characters, and if it's Sketchup Pro, there's a bug where it does not have the "Pro" part until after it finishes processing the Plugins and Tools folders, and draws to UI (toolbars and menus.)

                    I rejected this window title approach as too problematic:

                    
                      #  find_skp_hwnd_by_title(debug=false)
                      #
                      #  Try to find app window by title.
                      #
                      #  Highly modified from wxSU code.
                      #
                      def find_skp_hwnd_by_title(debug=false)
                      
                        require('Win32API.so')
                      
                        skp_window_id = 0
                        
                        findWindow = Win32API.new("user32.dll", "FindWindow", ['P','P'], 'N')
                    
                        # Set locale specific "Untitled" string Hash
                        #
                        # ** this won't work as is because some strings are unicode
                        #
                        notitle = Hash.new("Untitled")
                        
                        notitle['cs'] = "Názvu"           # Czech

                      I agree 100% with you.

                      BTW, when SKP runs your rb scripts, is the rb script first compiled by the Ruby interpreter, or is it interpreted like the old DOS Basic? Or compiled to P-Code?

                        Well it's not called a "compiler" is it?

                          😆 No, but I doubt it interprets characaters by characters at run time, it would be too slow. It has to pre-compile or something.

                            Well the actual Ruby Core modules, classes and methods, are themselves compiled C-functions.
                            The interpreter just "gathers" the arguments from the plain text scripts, and makes the C calls in the background.

                            If you have downloaded the Ruby C source... you can read the interpreter's source to get an idea of what's happening behind the scenes.

                              yeah! I've done that once with the RH Linux source. It's difficult when you're not the one who wrote it. It's easier to ask 😉

                              Going back to this SKP window handle thing, sometime it doesn't work when I double click on an SKP file. But it always work using the shortcut! I don't have wxSU installed. What do you think it could be?

                                Dan, Tom, Alienizer,

                                Sorry to pop up in this intersting discussion.

                                Does it mean there is a Win32api.so working for both Win32 and Win64 (Vista and 7)? I have problems with my current Win32Api version on Windows 7 - 64 bits.

                                Thanks

                                Fredo

                                  Apparently not, it's all 32bit only but Win32api.so works just fine in Win7/64 and Vista/64, so as in XP/64

                                    Apparently not, it's all 32bit only but Win32api.so works just fine in Win7/64 and Vista/64, so as in XP/64

                                    OK. Thanks. Then it must an issue with Jim's Ruby console (but I modified the code, so it may be my fault)

                                      Going back to this SKP window handle thing, sometime it doesn't work when I double click on an SKP file. ... What do you think it could be?

                                      While Sketchup starts up, and is processing the rubies in the Plugins and Tools folders, the UI is not yet finalized. The menus and toolbars are not built until all rubies that modify or create toolbars have been processed.

                                      It seems that the window title bar is also not finalized. If you have Sketchup Pro, when you double-click a SKP file, during the startup, the window title bar says "clickedfile.skp - Sketchup". It's not until the UI is finalized that it reads "clickedfile.skp - Sketchup Pro".

                                      BTW.. I have a solution that Always works (on Windows,) even if more than one Sketchup instance is running. Just need to decide how to implement it. (ie: modify a API module, put it an SKX submodule, or put it in a module of my own.)

                                      I'm not here much anymore.

                                        There are some quirks with some of the version system calls... look thru the source code for Daniel Berger's win32-api package.

                                          Thanks! I'll have a look.

                                            Is there a way to "wait" until SK is loaded? I'm not using the title bar caption to find the window, I'm using Process.pid and iterate all windows to match the pid.
