window size

how i can to get the x and y coordinates of a window in pixels to positionate a object in a determined location with ObjectSet(obj_name, OBJPROP_XDISTANCE, value_in_pixels)?
I want to draw one symbol at diferent locations in one window but the position relative to the window is important to me.

There's lots of text positioning code in this indie.

You could reach these by using windows api GET_CY and GET_CX.. something.. (consult the windows api programer reference..)

But you should try in a more simple manner..
try to type in an exact value, treat the chart-window as a fixed size windows..

Yet it could become more and more complicated..
