Hi,

Does anyone know how to grab a screenshot of the desktop (or a portion of it)?

Cheers

On Window's you press and hold Ctrl, then press Print Screen. It puts it into the clipboard. Then you can paste it into some application like Paintshop Pro.

On the Mac it's something like Apple-Shift-3, or Apple-Shift-4 to grab an area. Not sure if it's the apple key or the Option key.

As to doing it from within BlitzMax, that's another story.

A rough example:

Window:TGadget = CreateWindow("Desktop", 250, 250, ClientWidth(Desktop()), ClientHeight(Desktop()))

dsDC = GetDC(QueryGadget(Window, QUERY_HWND_CLIENT))
dhWnd = GetDesktopWindow()

BitBlt dsDC, 0, 0, ClientWidth(Desktop()), ClientHeight(Desktop()), GetDC(dhWnd), 0, 0, $00CC0020

Repeat
Until WaitEvent() = EVENT_WINDOWCLOSE
