dllstructcreate problem with string array

1 post in this topic

#1 ·  Posted (edited)

If I create a struct like this

$MonItStruct = DllStructCreate("int;int;char[100];int;char[40];char[40];char[40];char[40];char[40];char[40];char[40];char[40];c

har[40];char[40]")

then I can read the strings from element 5 onwards with memoryread. (Using nomadmemory.au3).

I can set the strings with DllStructSetData($MonItStruct,5,"something",$element)

and read with a memory offset of 112 + ($element - 1)*40 from the address of the start of the struct obtained with DllStructGetPtr($MonItStruct)

I expected that this would be equivalent to

$MonItStruct = DllStructCreate("int;int;char[100];int;char[10][40]")

But when I try to read this with memoryread I only get only the first character for the first string, nothing for the next strings, and DllstructGetData doesn't read the strings back either.

Why aren't the two constructions the same, and what should I have been doing?

Edit:Corrected wrong statement that DllStructGetData could read strings back from array of strings.
