set the bars to be located off the screeen by their cordinates

your framerate is set by the number of updatePreview calls. If you call the update 30 times in a second, you'll have 30 frames per second. Rather than having an event executed on every frame (which leads to thread execution timing issues related to your processing speed), it's a much safer method of working with an image at the time.

You also have access to the raw bitmap if you wish.

thank you Dj. I will do so with the bars but I've tried fast the framerate and gives this error:
Error HRESULT E_FAIL has been returned from a call to a COM component.

in this line of code: lbl_fps.Text =_camera.FrameRate.ToString();

yes, don't change that framerate. you can't change it or you'll get an error.

The way to change the framrate is to call the UpdatePreview() more often

I'll post you the piece of code since I don't understand what you mean:

timer1.Interval = 50;
timer1.Start();
_camera.StartCamera(WebcamChosen, panel1);


private void timer1_Tick(object sender, EventArgs e)
{
_camera.UpdatePreview();
lbl_fps.Text = _camera.FrameRate.ToString();
}


btw red stripes are far away from the screen. thx for that

Code:

timer1.Interval = 50;
timer1.Start();

lbl_fps.Text = (1000 / timer1.Interval).ToString();

_camera.StartCamera(WebcamChosen, panel1);

private void timer1_Tick(object sender, EventArgs e) {

  _camera.UpdatePreview();
}

Oh I didn't thought that the number should be so manual. Fixed and everything works. THe only "problem" now are the backgrounds of the images and labels that can't be transparent on visual studio 2010

Thx for the support
