Draw RECT to specific size

[Brian]

Hi,

How can I draw a rectangle to a specific size - I want to draw one 350mm x 450mm, irrespective
of what the Logpixels are

Any ideas?

There are a number of ways to approach this. 

1) You could use logpixels to create a conversion from disply dpi to mm.  Which would be compatible with the autodrawn windows.
2) You can change the mapping mode of the window to MM_LOMETRIC then any drawing command coordinates are in .1 mm instead of 1 pixel.  To do this you'll need a non autodrawn window by specifying @NOAUTODRAW as a window creation flag and draw everything in response to @IDPAINT.

Microsoft describes the mapping modes here:
