Passing an array of Chars byref to Delphi dll

P: 1
Im trying to get my vb program to talk to a Delphi written dll. I can get it to work as long as I only ask for the first char in a string but I cant seem to return the whole string from the dll
Delphi code
function GetInfo(info:pchar):longint;stdcall;external 'RRMifare32.dll';

Declare Function GetInfo Lib "RRMifare32.dll" (ByRef info() As Char) As Long

Dim info(12) As Char

Running this gives me a 'FatalExecutionEngineError' error, which I assume is because my dll is unable to interpret the char array from VB. Any ideas what I should be passing it as?
