Flicker ????

i just started to learn opengl, i made a tutorial making move square. i always see flicker on screen…i wrote code for the pixels “pixelDesc.dwFlags” definition and i wrote line on “on size” and “on paint” that was suppose to help me but nothing, i read that i can change the pixel values…no change…help…

Sorry, but this asks for a RTFM answer.
Seach the forum for double buffering (your_dwFlags |= PFD_DOUBLE_BUFFER) and if you had this already, try enabling VSYNC in the display control panel of your graphics board vendor’s OpenGL settings.
