Strange behavior of a variable

[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
