Strange behavior of a variable

Recommended Posts

Xerix
Hello

 

I just found that, declare a variable gives the same result with certain functions that if I had a dialog box.

 

For example
 
Global $var
 
MsgBox (4096,"",wingethandle ($var)) ; result handle
MsgBox (4096,"",winactive ($var)) ; result handle
MsgBox (4096,"",winexists ($var)) ; result 1
MsgBox (4096,"",WinGetProcess ($var)) ; result process
MsgBox (4096,"",WinGetState ($var)) ; result 47
 
These functions should t it not give a result as if it is a dialog box?
I thought rather getting errors using these functions
 
Thank you.

Hi,

Declaring a variable without initializing it is automatically initialized with a blank string.

A blank string for these functions corresponds to the active window.

You can check by yourself using the WinGetTitle function.

Br, FireFox.

Don't see anything strange about it, returns exactly what the functions are supposed to return as far as I can tell.

Global $var

MsgBox (4096,"wingethandle",VarGetType(wingethandle ($var)) & @CRLF & wingethandle ($var)) ; result handle
MsgBox (4096,"winactive",VarGetType(winactive ($var)) & @CRLF & winactive ($var)) ; result handle
MsgBox (4096,"winexists",VarGetType(winexists ($var)) & @CRLF & winexists ($var)) ; result 1
MsgBox (4096,"WinGetProcess",VarGetType(WinGetProcess ($var)) & @CRLF & WinGetProcess ($var)) ; result process
MsgBox (4096,"WinGetState",VarGetType(WinGetState ($var)) & @CRLF & WinGetState ($var)) ; result 47

Thank FireFox
 
I didn't know that.
 

JohnOne, it's not strange if you know how it's works, but it's strange if you are a newbie  :sweating:
