c# - Disable WinForms ProgressBar animation

Question

Is there a possbility to disable animation of the progress bar?

I need it for some pocess which is paused and not running at the moment. An average user would think the process is running if the progress bar is being blinking.

The advice to create own progress bar control is not what I'm looking for.

You can use the Vista progress bar's paused state, like this:

// Assuming a Form1 with 3 ProgressBar controls
private void Form1_Load(object sender, EventArgs e)
{
  SendMessage(progressBar2.Handle,
    0x400 + 16, //WM_USER + PBM_SETSTATE
    0x0003, //PBST_PAUSED
    0);

  SendMessage(progressBar3.Handle,
    0x400 + 16, //WM_USER + PBM_SETSTATE
    0x0002, //PBST_ERROR
    0);
}

[DllImport("user32.dll", CharSet = CharSet.Unicode)]
static extern uint SendMessage(IntPtr hWnd,
  uint Msg,
  uint wParam,
  uint lParam);
