hi sir (again)
sir tell me but is difference between WM_paint and wm_erasebkgnd
plz sir its request that tell me one function daily only one i think i does not take much time plz.........plz.........
I create a frame and rotate the screen in 270 degree.
But if I wish when I set setting->screen->orientation->portrait,
the screen will not rotate until I close the fram.
What could I do for the question??
The %s directive makes printf() and friends expect a string pointer on the stack. If you pass an object, such as std::string, you'll give it "garbage". If you give it a pointer to the internal string buffer instead, it'll work.
