are you asking: "how to use winforms to draw an image" ?

(then the answer would be: please don't do that, because you would have to mix opencv code and managed c++, which is the straight road to hell, especially, if you're a noob !)

yes I was tried car counting using openCV in c++ , but i want to display the picture and the counter in windows form.

can we somehow convince you, just to use imshow() / waitKey() ? (at least for now.)

again, managed c++ uses an entirely different programming model, orthogonal to opencv's RAII concept.

there's a ton of subtle pitfalls, if you mix both,

save yourself the trouble, and build a nice car detection first. form follows function, right ?

.my friend thank for you good advice. my car detection and counting program are complete, all I need now a way to display the result and some commands buttons to open the video.

You and use GTK+ UI library for developing UI along with c++ core logic. see here https://www.gtk.org/development.php To show image from opencv you can use pixleBuffer in GTK or either first you write opencv image to a directory then read the same via GTK ui .
