There's a few web apps that I've done in recent months that needed to accomodate an image upload. Every now and then, we'd get emails from Mac users claiming that they were unable to upload images. Due to being backlogged with requests, it wasn't until today that I had the timeto experiment with things enough to remedy the situation.

At any rate, here is some standard simple .NET code for use when uploading a file via http post:

Dim objFC As HttpFileCollection=Request.Files
Dim objFile As HttpPostedFile=objFC.Get(0)

objFile.SaveAs(Server.MapPath(“/wherever/whatever.jpg“))

Now this works fine when uploading from a Windows machine and some Mac's, however when I tested this it was on an OS9 Mac and this code did not in fact work very well (the file got saved, however the script request never completed; was pretty weird). It just took a little experimenting with things, and I got the code to work by doing the following:

Dim objFC As HttpFileCollection=Request.Files
Dim objFile As HttpPostedFile=objFC(0)

objFile.SaveAs(Server.MapPath(“/wherever/whatever.jpg“))

Pretty simple huh? I know it's nothing major, but figured I'd share anyway. It was driving a couple of our Mac using clients nuts. Of note is that when in situations where using a webform is an option, this works without problems on either OS. However, some of our apps are still not completely changed over from Classic ASP to .NET, thus using a webform in some circumstances is simply not an option right now.
