video = new cVideo(pictureBox1.Handle, pictureBox1.Width, pictureBox1.Height);这里的video问题怎么解决的啊?
说上下文不存在video,怎么定义啊?

video 是你定义的变量名,cVideo 是你要初始化的类名,初始化应该这样写：
cVideo video = new cVideo(pictureBox1.Handle, pictureBox1.Width, pictureBox1.Height)

video = new cVideo(pictureBox1.Handle, pictureBox1.Width, pi handle screen.width*0.35) this.width=screen.width*0.40"border=0> 这是 onload="javascript:if(this.width>screen.width-350)this.width video this.width=225;" border="0" this._container.style.width = w + "px"; 英语翻译Video Games Inc.recently developed a new video game.Its these are my video tapes. ( )(it)are new. div width=100px和div style="width:100px"的区别 C++中,HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE); >> t=(0:pi/100:pi)';
