Hi, I have a system that uploads images as BLOBs in a database. I also have a function that I use to resize uploaded images before saving as files. I would like to combine these two by resising the images before inserting them as BLOBs. My problem is that (apart from being new to file stuff) my resize function returns a Resource ID which of course is not the same as the file handler that was passed to it, it's a reference to an image...

I don't want that. What I want is some "real" zoom effect. So I continued my search...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
