Use variable for function

8 posts in this topic

Hi, i like to generate a variable from a string and use this variable as a function. Examples will help to explain my Problem:

$var = IniWrite
$var 
("info.txt""Update ..... ) 

This works fine but if i change it like this ($var1 = IniWrite) it returns:   ==> Variable cannot be accessed in this manner.:

$var1 binarytostring("0x496E695772697465",    $SB_UTF8)
$var1 ("info.txt""Update ..... ) 

Same when using Assign.

 

 

I noticed something simliar when playing with BinaryToString. If i generate "x" with XOR, lets name it $axx and try to replace the "x" here:

binarytostring("0x496E695772697465" ,    $SB_UTF8)    like this    BinaryToString("0" & $axx   & "496E695772697465 ,    $SB_UTF8)

it fails but if i add this func it will work again:

if  $axx "x" Then
   $axx "x"
endif 

I think the calculatet terms are somehow different? Is there a solution?

Greetings

Idk if the two above ran the

binarytostring("0x496E695772697465",    $SB_UTF8)

to see that it's the string IniWrite

What you're trying to do as is won't work, however it's still possible ;)

$var1 = binarytostring("0x496E695772697465", $SB_UTF8)
Call($var1, "info.txt", "Update .....")

Call will take a string as an argument and call the name of the function, your string created from a binary string. Check out the help file, you can also use an array to pass all the parameters to your function using Call

I believe that he is using the term "string" in the general sense.  Please correct me if I am wrong.

What is this magic?!?  Is there a term for this method/approach besides, 'assigning a function to a variable'?  Not sure exactly how or why I would use this other than shorthand, but still neat.

Functions in AutoIt are now first class objects which means you can assign a function to a variable. This works in place of using the Call function.
