I found in windows solution:

HDC hdc = ::GetWindowDC(NULL);
int width_mm = ::GetDeviceCaps(hdc, HORZSIZE);
int height_mm = ::GetDeviceCaps(hdc, VERTSIZE);
::ReleaseDC(NULL, hdc);

But how will be in linux?

Well!
Thank you to Max and Andrei for help me to detect monitor size in millimetres:

I propose to add a function in u++ to get windows size in millimetres
for example:

Size GetScreenSizeMM();

for windows will be:

Size GetScreenSizeMM(){
return(GetSizeCaps(HORZSIZE, VERTSIZE))
}

and for linux:

Size GetScreenSizeMM(){
return Size(DisplayWidthMM(Xdisplay, Xscreenno), DisplayHeightMM(Xdisplay, Xscreenno));
}

This function will be helpful for me and other programmers! It can be integrate in print preview for zooming 100% size!
