Passing operator in function.

5 posts in this topic

Hey guys!

Such an awesome program, figured if I'm going to be working with it, I need to join up on the forums and ask questions for problems I can't find an answer for.. Here's the dealio:

I'm trying to pass an operator through a function call. It's basic math, with some formatting applied, so I'm gonna try to simplify the code into basic form.. I may be using terrible coding methods, but as I progress it tends to get better.

Func math(byref $op, byref $val)
    $value1 = GUICtrlRead($Input1, 1)
    $value2 = StringTrimLeft($value1, 1)
    $value3 = $value2 $op $val))
EndFunc

call:

math("+", "7.50")

Something simple will probably cure the error that I keep getting, I've been searching for a while without much luck. It's a pita to find anything without being able to get specific.. Thanks in advance for anyone thats willing to help another noob. :mellow:

Like this:

;~ Func math(byref $op, byref $val)             ; no real need to pass ByRef as you don't modify these arguments
Func math($op, $val)
;~  $value1 = GUICtrlRead($Input1, 1)       ; let's simplify this into a fixed value for testing
;~  $value2 = StringTrimLeft($value1, 1)        ; why it that here? Let's forget it for now
    Local $value1 = 123.456
    Return(Execute($value1 & $op & $val))
EndFunc

ConsoleWrite(math("+", "7.50") & @LF)

Func math($op, $val)
;~  $value1 = GUICtrlRead($Input1, 1)       ; let's simplify this into a fixed value for testing
;~  $value2 = StringTrimLeft($value1, 1)        ; why is that here? Let's forget it for now. **ADD - This removes a currency symbol from the input box text value.
    Local $value1 = 123.456
    Return(Execute($value1 & $op & $val))
EndFunc

Added some explanations to the comments in your post.. Thanks for the help man!

lulz, r u using autoit to make a lisp interpreter or somefink?

Eh? Not sure I understand your pun.. Thanks though...

The end result is this;

Func math($var1, $var2, $var3)
    $val1 = GUICtrlRead($var1, 1); Read InputBox1
    $val2 = StringTrimLeft($val1, 1); Remove $ from InputBox1.Value
    $val3 = Execute($val2 & $var2 & $var3); Execute expressions
    GUICtrlSetData($var1, "$" & stringformat("%.2f", $val3)); Display result in InputBox1
EndFunc

math($InputBox1, "+", "7.50")

I'm sure it's probably sloppy as far as standards go but, 1 group is as follows:

1 input box - text set at "$0.00"

2 buttons - 1 button adds to input box text, the other subtracts, keeping the text formatted with 2 decimal places and the monies symbol.

GUI will contain 20+ input/button groups, different prices assigned to each.

With a little time I should be able to trim the code down even more, any advice is welcome though.. Thanks again for the help guys!
