Rick,
Thanks for writing back... I guess nothing's perfect, and I'll have to make do... But I might only be willing to pay $98.99 for wwIPStuff now... *grin*
I think I'm going to split the files up into 1 MB chunks before sending them, and any files to be saved larger than 1 MB will be saved to the disk 1 MB at a time... Since I'm never going to be passing a filename to httpgetex(), I might just leave the line that builds tcBuffer commented out. We're all for cheap hacks around here.

As for sending data over HTTP... We'd use FTP, but my boss is afraid someone might grab the plaintext username/password and then the file as it's going down the wire and get a free copy of our software... So I have to use HTTP with FoxISAPI to authenticate the user over HTTPS, then give them a cookie and switch to HTTP to send them the file with ASP (in a hurry, before the cookie expires). It's a tad messy, but it's the best solution I could come up with. Any better suggestions are always welcome. (I'd rather not authenticate and create temporary accounts that would only allow one user to be on them at a time... ick.)


>>I downloaded wwIPStuff a few days ago to use in one of our applications for downloading automatic updates to our software. I was originally using MS's Internet Transfer Control, but it lacked a way to update a progress bar (not a good thing when getting >20 mb files over a modem).

>>I'm using httpgetex() with the wwIPStuff class control on my form. Everything appears to work fine except for large files. I was taking each lcCurrentChunk in onhttpbufferupdate() and storing it to a new element in an array. When httpgetex() returned, my code added the array elements together and spit out the binary file.

I changed the array operations to just do a StrToFile() with append set to True after getting each chunk. This also worked fine, until I tried that 7 mb file again. This time I suspended the program and saw the out of memory error was occurring in httpgetex() in the wwIPStuff class. The error is occurring on this line:
