[snip] The DLL was built specifically with a COM interface which I accessed using the PHP COM functions (as I'm sure you've seen already). The DLL authors had to rejig their original code a little, but it was a far less painful process than compiling the DLL into PHP. However for the next revision we are likely to move the DLL code into the .NET framework, build a SOAP interface to it (C#) and let PHP talk to it that way. Although that's more of a political decision than a technical one, I'm just mentioning it incase the idea is useful for you. [/snip] Unfortunately I may not be able to have the DLL re-built with the COM interface. It is an older DLL containing engineering functions and it is huge. The real dingle here is that I only need to access some of the functionality of the DLL. I also do not want to compile it into PHP as it (the DLL) is a moving target. This may be one of those projects where I say, "Give me some more development folks and we'll get it done right." otherwise we may not be able to do the project as it exists. I am researching the requirements for adding the COM interface now. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
