It is saying that $result is not an array. The issue resides in ImageSearch.au3 as indicated by the compiler.

$result = DllCall("ImageSearchDLL.dll", "str", "ImageSearch", "int", $x1, "int", $y1, "int", $right, "int", $bottom, "str", $findImage)

    ; If error exita
    If $result[0] = "0" Then Return 0

You say that the DLLCall should return a string, find out what it is really returning using ConsoleWrite. You can also use the function IsArray to assert an array is returned.


Post your code because code says more then your words can. SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y.

DllCall ( "dll", "return type", "function" [, type1, param1 [, type n, param n]] )

"return type"

As I said, you think the dll should return a string. What I am saying is "Subscript used with non-Array variable." means that AutoIt does not see '$result' as an array or string when you are using subscript. (A string is an character array).

In your error checking if the string returned is blank or invalid then $result[0] = "0" will fail. I would do the following.

If Not IsString($result) Then Return 0
If $result = "" Then Return 0
ConsoleWrite($result & @CRLF)
