martin Posted October 14, 2011 Share Posted October 14, 2011 (edited) You need to add :cdecl to the return type so "ptr:cdecl" not "ptr". See the help for dllcall. Also, make sure the dll is in the script folder or use the full path.

martin Posted October 14, 2011 Share Posted October 14, 2011 Can you give a link to the VB example, and better still a link to information on decrypt_dll.dll? If the function _dcrypt returns a pointer to a buffer how do you know how big the buffer is? How do you even know it returns a pointer? You have used $ize + 1 but where does $size come from? Also you have used a char array but the function definition says byte so that could also be significant. But at the moment I don't have enough information about the function to make a sensible suggestion.
