query: regarding url support for opening drawings
hi all..
i have developed an mfc activex control for displaying and processing of dwg fiels, using the library dwg direct 1.11.01.00.
i encountered a problem, while opening the drawing, when it is executed from a web server.
so how can i implement this feature..
is there any function, with the dwg direct library, which has url support for readfile() function.
tia

readfile() calls
oddbstrembufptr oddbsystemservices::createfile().
you can override this function to recognize url, download the file into temporary location and return oddbstreambufptr.
surely your implementation of streambuf for remote file can be optimized (download a file in a separate thread, download the file by portions upon request etc.)
