How do you read a window handle from an INI file?

5 posts in this topic

This seems really basic but I am having issues get this to work.

Run(@WindowsDir & "\notepad.exe")

Do
Until WinExists("Untitled - Notepad", "")

$handle = WinGetHandle("Untitled - Notepad", "")
IniWrite(@ScriptDir & "\test.ini", "handle_value", "handle", $handle)

$handle2 = IniRead(@ScriptDir & "\test.ini", "handle_value", "handle", "error")

;$handle and $handle2 seem to be the same
ConsoleWrite($handle & @CRLF)
ConsoleWrite($handle2 & @CRLF)

;WinClose($handle) ;does work
WinClose($handle2) ;does not work

Windows handles change every time the program runs, so storing it is not a very good procedure. Just get the handle when you run the program and use that.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

IniRead() returns all values as strings so you need to use Hwnd() to convert it back to a handel

Run(@WindowsDir & "notepad.exe")

Do
Until WinExists("Untitled - Notepad", "")
$handle = WinGetHandle("Untitled - Notepad", "")
IniWrite(@ScriptDir & "test.ini", "handle_value", "handle", $handle)

$handle2 = HWND(IniRead(@ScriptDir & "test.ini", "handle_value", "handle", "error"))

;$handle and $handle2 seem to be the same
ConsoleWrite($handle & @CRLF)
ConsoleWrite($handle2 & @CRLF)
WinActivate($handle2)
WinClose($handle2) ;Now works

I know it's not generally a good idea but I have a script that starts/runs several other scripts and then those scripts report back to the script that started them through an INI file....It basically gives me multi thread like results because I can have my program do more then one thing at the same time.

Thanks Bowmore.

Just make sure that when your main script runs, it updates the INI file everytime with its new HWND.

Take into account if the main script crashes while you have other scripts running, have a way for the other scripts to re-read the INI file periodically to see if there's a change in the HWND.

Sadly, he isn’t me, but if he stopped using ladies scented body wash and switched to Old Spice, he could smell like he’s me. Look down, back up, where are you? You’re on a boat with the man your man could smell like. What’s in your hand, back at me. I have it, it’s an oyster with two tickets to that thing you love. Look again, the tickets are now diamonds. Anything is possible when your man smells like Old Spice and not a lady. I’m on a horse.”
