A customer asked,
Is there a way to turn off Full Window Drag on a single window? I have a resizable control that I would like not update itself while resizing.
It so happens that I wrote a sample program ages ago to illustrate how to do this. You can find it in the Platform SDK under winui\fulldrag
. The source code is also reproduced in this Knowledge Base article.
In addition to deferring painting, you may also want to defer layout if layout is expensive for your window.
