yet another problem

this should probably be obvious to me but I can''t figure it out.

LPRGNDATA region_data;
region_data = (LPRGNDATA)new(sizeof(RGNDATAHEADER)+sizeof(RECT))
-> memcpy( region_data->Buffer, ddclprect, sizeof(RECT));
region_data->rdh.dwSize = sizeof(RGNDATAHEADER);
region_data->rdh.iType = RDH_RECTANGLES;

You''re missing a semicolon at the end of the previous statement.
When searching for this type of error, think of how the compiler operates. It processes each ''token'' (punctuation, identifier, number, etc) one at a time. When it finds a token that it is not expecting, it usually emits a syntax error. So, when you get a syntax error, look at the form of the statement right before it reported the error; it is usually there.
Also, many compilers will get confused after syntax errors, and may report bogus errors after a certain point. If you fix the first errors, and recompile, sometimes a lot of error messages disappear.

This should work:
region_data = (LPRGNDATA)malloc(sizeof(RGNDATAHEADER)+sizeof(RECT));
memcpy( region_data->Buffer, (void *)&ddclprect, sizeof(RECT));
why do you use "sizeof(RGNDATAHEADER)+sizeof(RECT)"?
region_data = (LPRGNDATA)malloc(sizeof(RGNDATAHEADER)+sizeof(RECT));
memcpy( region_data->Buffer, (void *)&ddclprect, sizeof(RECT));

because I read it some where. from 102 errors to 0 in a minute that''s got to be a new personal record!
so if I got this code right any bitmaps I blt to the backbuffer will be clipped to the backbuffer.
