 Posted: Tue Oct 13, 2009 12:30 am Post subject: Is there a reason why winGet returns different values? |
 |
|
Consider the snippet:
| Code: | Run, %programme_to_run%, , UseErrorLevel, cmd_PID
WinWait ahk_pid %cmd_PID%,,10
if not ERRORLEVEL
{
WinGet, win_ID, ID, ahk_pid %cmd_PID%
if !win_ID
MsgBox, No matching windows
unique:= winexist(ahk_pid %cmd_PID%)
WinGet, active, ID, A
}
else
MsgBox, Errow waiting for ahk_pid %cmd_PID%
MsgBox, %win_ID%`n%unique%`n%active%
|
Why can the three values be different (apart from the window not being active)??
What I thought would be easy was to get the windowID from the ProcessID returned from Run and close it later... but the close fails because the Win_ID is usually not set to the same value as active.
Any ideas?

to use pid you have to have full path to exe

Thanks: where do you mean? %programme_to_run% is the full path, and Run returns the correct PID.
WinWait ahk_pid %cmd_PID% finds a window OK
WinGet, win_ID, ID, ahk_pid %cmd_PID% does not return the same ID that WinGet, active, ID, A returns (when the appropriate window is active).

perhaps the program you are running is creating multiple windows ? (you may not be able to see all of them) in that case also specify a window title or something like My Window Title ahk_pid %pid% ... iirc somewhere i read that if there are multiple windows that match the wintitle parameter, it returns the info for the topmost.

Thanks for the pointer:
| Code: | | Get, NumberWindows, List, ahk_pid %cmd_PID% |
is very revealing! 
Plus it helps if you turn off DetectHiddenWindows

should be | Code: | | unique:= winexist("ahk_pid " . cmd_PID) |

Yes, of course: thanks.
I presume that WinExists() was returning the top-most, or last opened, window?
