Is there any way to Raise WM_NCCALCSIZE message? I mean to force the window to recalculate its client area. Send what message to do that?Thanks.

You can send it yourself . . .

Hm.. no good. WM_NCCALCSIZE is something that windows sends and then windows does the rest of the job. So, if windows is not the one sending it, it would not do anything. Your window will simply handle it and nothing comes out of it.

Anyways, a little poking around the APIs listed under See Also for WM_NCCALCSIZE would have revealed that there are some APIs that trigger this message.

Why don't people read documentation anymore

So to close the thread the answer seems to be, after reading @kirants reply who for some reason concealed his answer in a shroud of mystery, you use SetWindowPos with flag SWP_FRAMECHANGED that will trigger WM_NCCALCSIZE even when the size of the window hasn't changed. Tested it in my case and it works as expected.
