PHP and OLE objects

Hi all, I am having a problem with a PHP script, in which I am using a self-written OLE object to provide data to the script. I have two other OLE DLLs that I also use in PHP scripts which work fine. I wrote all of the DLLs in Borland Delphi, btw. (I am running PHP 4.0.6 and Apache 1.3.20 on Windows 2000 Pro) For some reason, whenever I try to access one of the Char/String variables (in only this DLL) from PHP, it returns a warning: "Error in php_OLECHAR_to_char()". I have been trying to fix this problem for some time now, and am having no luck finding a source. I have had this message before, but it was easily fixed by setting a default value for the strings (in the DLLs) to a single ascii-32, so that the return would not be blank. The only difference between this object and the others is that the low-level delphi code uses pointer variables to set up the data access, whereas the others do not. I have used this object in other non-PHP projects (and tests :) and it works as it is intended to. Also, all other types of variables in the object are intact. Can anyone suggest a source of this problem? On what conditions does php_OLECHAR_to_char() error out? Thanks in advance, Joshua Ecklund - mProwler
