It really looks like that's where the market is headed, following the Microsoft monopoly. _______________________ Michael B. Johnson

The minimum requirement for the .NET runtime is Win98/ME or NT4, it won't run under Win95 AFAIK. > Before you do that though (or perhaps in addition to doing it) you might like to check out the LoadImage API.

How is loading the JPEG, saving it to disk then reloading it simpler than just loading the JPEG? ;) Also, is the problem really in loading the JPEG off disk or displaying it in the picture box? At least when VB returns the image in a StdPicture object it appears to be a DIB, which should mean it has no problems loading the image, just displaying it. I've loaded a 6000*6000*24 bitmap in WinME directly into a StdPicture object, but loading the same image into an AutoRedraw picture box simply hung the app so I couldn't say for sure. Also, WinME may not have the old 16mb limitation it's been a long time since I worked with any of this stuff. > The LoadImage API, whch will work under Win9x as well as WinXP, can > load and stretch a bitmap into a device and it appears to use its own stretch > algorithm which to my eyes appears to be at least as good as halftone. LoadImage()'s scaling uses StretchDIBits() internally and sets COLORONCOLOR stretch mode which is natively available under Win9x anyway. If you're running on a Win9x/Me machine then setting the stretch mode to HALFTONE actually uses COLORONCOLOR internally, so although it appears the call has succeeded it actually did something else.

That's just Google's algorithm for matching your search query to something it's familiar with. --- Stefan Berglund

This'n does though <g> (dropped the quotes and the reference to NT)... and, they're mostly VB6 related.... and, since there are at least 2 in the list from vbaccelerator.com, that's where I'd head for sample code.
