Thanks. In fact, i want to use DirectGraphic to display 2D. And i know i need create four vertices for each image(texture), and then i need create vertex buffer and copy the vertices data to the buffer. So i meet a problem that i always rebuild the size of vertex buffer and refill the data to it when i have an new image. Else, how can i render the new image?
Also, i found a lot of materials from gamedev.net about using DirectGraphic to render 2D. But those articles are just render an image. My problem is still unsolve.
So i want to find some websites to teach more about this.
