Read & Write as Bool

[FaridAgl]

You know, in AutoIt we don't need to declare datatype, BTW we have something like Number(), Int(), Hex(), String() etc that are useful in some cases,

I was thinking about Bool() as well.

Why? Let me explain.

I have a GUI (It's just an example), it has some CheckBoxes on it, i want to save each CheckBox's values on Exit:

If Checked Then IniWrite(1)
Else IniWrite(0)

And then read it on Start:

If IniRead() = 1 Then Checked
Else Unchecked

It's OK right?

But if we have a Bool() command we can do it like this:

IniWrite(Bool(CheckBox))

And on Start:

same as previus.

I know in AutoIt 0 = False and any other numbers are True.

Maybe it doesn't make any sense in this example, but i'm sure there are so many better usage for it.

I'm wondering why there isn't a Bool() command while we have Int(), Number() etc.

It's simple to make a User-Function for it, in fact i'm doing it for myself, but i just want to know do you thing it can be a good option for AutoIt or not?

Something like this?:

Func Bool(Const $var)
    If $var = 0 Then Return 0
    Return 1
EndFunc

Maybe even:

Func Bool(Const ByRef $checkbox)
    If GUICtrlRead($checkbox) = $GUI_CHECKED Then
        Return 1
    ElseIf GUICtrlRead($checkbox) = $GUI_UNCHECKED
        Return 0
    EndIf
EndFunc

#include <GuiConstantSex.au3>

                        GUICreate           ('',            100,    100,    500,    500)
Global Const $cb      = GUICtrlCreateCheckbox("Click Me",    10,        10)
Global Const $display = GUICtrlCreateLabel   ('',            10,        40,        10,        20)

GUISetState(@SW_SHOWNORMAL)

display_state(Bool($cb))

While True
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cb
            display_state(Bool($cb))
    EndSwitch
WEnd

Func Bool(Const ByRef $checkbox)
    If GUICtrlRead($checkbox) = $GUI_CHECKED Then
        Return 1
    ElseIf GUICtrlRead($checkbox) = $GUI_UNCHECKED Then
        Return 0
    EndIf
EndFunc

Func display_state(Const $state)
    GUICtrlSetData($display, $state)
EndFunc

I'm sure you meant this.

If Return True

ElseIf Return False

[jaberwacky]

Well, I was thinking he wanted an integer to write to an ini file.

[JohnOne]

You are probably right about that.

But the question is, is this a good suggestion for a native Autoit function?

For me it is not, since it's trivial to make it yourself.

[FaridAgl]

Well, thanks. I coded something like that.

I noticed that AutoIt counts strings as True, is it OK?

$var = "blah blah blah"
If $var Then MsgBox(0, '', '')

And it shows the MsgBox.

There are so many good Functions in AutoIt that we can code them ourselves, what about removing all of them from AutoIt?

I think it evaluates the ascii number of the strings or something and so like you said anything other than zero is True.

[JohnOne]

Or an empty string

$var = ""

If $var Then MsgBox(0,0,0)

It's a question if nothing else

my answer is no.

If they did, what do you think autoit would be?

Hi all,

AutoIt uses the following conventions for true/false:

Numbers: 0 = False, everything else = True

Strings: "" = False, any string with content = True

Boolean: Well you can guess that!

Basically you must be careful with strings (which are returned by several AutoIt functions) as a literal string "0" will be regarded as True. If you want store a Boolean in a file as 0/1, you need to use Number on it when you read it back to make sure you get the correct interpretation.

Thanks Malba,

The information you gave us is enough for me to understand how AutoIt handles Boolean.

I'm going to play with that.

End of Thread of me.

[Melba23]

D4RKON3,

I thought I posted a reply - who is this Malba guy?

Just kidding - glad I could help.

Oh sorry, i meant Melba,

Actually i'm searching for a good glasses, maybe i made another thread for it!!!

Thanks again.

How about passing the values as strings and checking their values.

 

If StringCompare(StringStripWS(StringLower($CmdLine[2]), $STR_STRIPLEADING + $STR_STRIPTRAILING + $STR_STRIPSPACES ),"true")=0 then

//

Endif

@ur You've been around long enough to know better than to resurrect old threads, especially after just shy of 8 years. I doubt the OP, who hasn't even been online for a year, is still trying to find the answer to this.
