    Image flickering in form

    Hello

    I try to insert a background image to my forms
    but when i try to run the application - the form is flickering
    why it's happen?
    I don't do any changes concerning the Background in the program
    I use the VS 2005 C#
    ?

    Are you perhaps redrawing the entire image on every WM_PAINT, although only a small area is being invalidated?

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    I just choose in the properties of the form "image background"
    I didn't write any code for this background?!
    What the problem

    Does it flicker when you say move a form atop of it or when you resize. You can set the doublebuffering property to true or manually draw to the buffer and render it within the paint event using a DoubleBufferedContext and BufferedGraphics.
