WinGetTitle and then switch to it as needed

[Yera]

Hello, I am using 2 hotkeys in an au3 file: one to get the current window title. And the other to switch to that window as needed. Below is my code, which gives an error when I want to switch to the Window: " Error: Variable used withut being declared." 

#include <WinAPI.au3>
HotKeySet("^+g", "GetThisWinTitle")
HotKeySet("^+s", "SwitchToTheWindow")
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE
Func GetThisWinTitle()  ; 
 $sAppTitle = ( WinGetTitle(""))
 EndFunc 
Func SwitchToTheWindow() 
WinActivate($sAppTitle) 
EndFunc

Seems that the variable, $sAppTitle, is not available when I try call it to switch. Would appreciate any help. Many thanks!

I think $sAppTitle is a local variable only present within your function that you set the value in (GetThisWinTitle). Try declaring $sAppTitle:

Global $sAppTitle

outside of your function declarations.

You don't need that first set of parentheses in line 7, and WinGetTitle is being used incorrectly also. See the example code (in the helpfile) for that function.

Great thanks! Global did the trick. Also, adjusted: $sAppTitle = WinGetTitle("")

All very best!

Sorry to revamp this thread, but it seemed appropriate as it is related.

Any idea how to switch to window that has variable title?

ie not always the same.

(To be precise, I wan't to create a snippet which would switch me to Kmplayer, but kmplayer has titles like "[5/5] Some_Movie.avi". ie. it uses what it currently plays as a title.)

@Zch - It depends on how and where it is different. Window Title recognition has a few Modes, mentioned in the Help file.

For instance, the default Mode, recognizes letters from the start of the name, so if the first five don't change, just use them ... or something like that. You can also get a Handle for the first Window Title, and any subsequent renaming of that window title won't cause an issue, as the Handle will remain the same. I've used that last (a single instance/many page changes) with FireFox quite successfully.

It changes completely, ie it always changes to the title of the video/audio file it's playing. except if I just start the program without loading playlist/video/audio, in which case I get "The KMPlayer" as windows title. 

I think it's good idea with using the windows handle. Must read more docs.

Thanks for the tip, I will post if I figure something out.

You can find it by it's class.
