If ... Then question

[crest]

Hey guys

for some reason "If .. Then" can only handle a single statement after the "Then" like explained in the helpfile

Conditionally run a single statement.

If <expression> Then statement

Is there any way to have two or more statements?

in c++ you can simply put as many statements as you want, you just need to bracket them like:

if (expression)
{ statement1; statement2; ...}

My own Code looks like this:

#include <GUIConstants.au3>
Global $amount
GUICreate ( "Conjure Water v1.2b", 300, 200)

$slider = GUICtrlCreateSlider (10, 30, 280, 20)
GuiCtrlSetLimit (-1, 20, 10)
$button = GUICtrlCreateButton ( "OK", -1 , 100 , 80, 20) 
GuiSetState()
GuiCtrlSetData ($slider, 0)

While 1
    $tempvar = GUiGetMsg()
    
    If  $tempvar = $button Then $amount = GuiCtrlRead ($slider)

    
    

Wend

I actually wanted the "IF ... Then" to save the Slider Position into $amount and then exit the While-Loop

Yet i cant think of a way to do this (damn i suck)

GUICreate ( "Conjure Water v1.2b", 300, 200)

$slider = GUICtrlCreateSlider (10, 30, 280, 20)
GuiCtrlSetLimit (-1, 20, 10)
$button = GUICtrlCreateButton ( "OK", -1 , 100 , 80, 20)
GuiSetState()
GuiCtrlSetData ($slider, 0)

While 1
    $tempvar = GUiGetMsg()
    
    If $tempvar = $button Then
        $amount = GuiCtrlRead ($slider)
        ExitLoop
    EndIf
Wend

It was probably a Syntax error. Recreate the script the way you had it and see if it gives you the same error. A syntax error just means that something was not in the correct order or something was misplaced. Its kinda like rearranging a sentence like 'Crest walks the dog'. You can write it this way or 'The dog Crest walks" and both ways communicate the same thing to you, however when scripting, if it is not EXACTLY the way it SHOULD appear, you will just get an error.

As a general sytax rule when using If statements in AutoIt put the stuff after Then on the next line, not the same line. This small Change can be the difference in your script working or not.

So always make this:

If $tempvar = $button Then $amount = GuiCtrlRead ($slider)oÝ÷ غ(X¤zØb±«­¢+Ø)%ÀÌØíѵÁÙÈôÀÌØíÕÑѽ¸Q¡¸(ÀÌØíµ½Õ¹ÐôÕ¥

Hi,

you can check those things on your own. Like:

#include <GUIConstants.au3>
Global $amount
GUICreate ( "Conjure Water v1.2b", 300, 200)

$slider = GUICtrlCreateSlider (10, 30, 280, 20)
GuiCtrlSetLimit (-1, 20, 10)
$button = GUICtrlCreateButton ( "OK", -1 , 100 , 80, 20)
GuiSetState()
GuiCtrlSetData ($slider, 0)

While 1
    $tempvar = GUiGetMsg()
    ToolTip(GuiCtrlRead ($slider))
    If $tempvar = $button Then
        $amount = GuiCtrlRead ($slider)
        ConsoleWrite($amount & @LF)
        ExitLoop
    EndIf
Wend

So long,

Did I understand you correctly there litlmike ? Are you saying that this code doesn't work :

If $tempvar = $button Then $amount = GuiCtrlRead ($slider)

If so, you're wrong, as it does work.

just to reduce errors and make it more clearly

Thx for the advanced help btw

Reduce errors? Shouldn't ? Well, actually that one-liner doesn't produce any errors while

the second does, because of a missing EndIf. Personally I always use one-liners when I

only need it to execute one statement...oh, well that's me.

I agree with you
