how can i execute a channel tv in a VFP form?

Perhaps someone else knows what you want. I don't. Please be more explicit.

i want to execute a VFP form with a window that runs a TV program. It´s possible?

You may directly linked to a Television (I assume cable)? Or the show a pre-recorded tv channel (like showing a DVD)?
If it is the first one, your computer has to be equiped with an NTSC decoder (Or PAL if your other parts of the world). But doable.

What's your goal? Wrinting a video player? Take a look into vfp samples, there is already such a thing.

Most TV USB sticks come with a software to watch tv with them and some of them integrate with Windows Media Center. You can include any windows window into the vfp _screen or a vfp form via Windows API SetParent (or was it SetParent Window). If this is about watching tv while you're programming for the convenience of still having the vfp IDE maximised, that might be the easiest solution. If it's about writing your own video player it's a totally different task.

thanks for your sugestions. The situation is in a medical clinic that the monitor has a VFP form that calls the turn of the costumers and when they wait ther turn they watches a Tv program in the same monitor
