Hi SridharV,
To show an animated gif in the background of a form, we can set the BackgroundImage of the Form to a gif image and then use ImageAnimator to handle the animation. This is a code snippet:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//Enable double buffering to reduce flicker.
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
//Enable paint via message to reduce flicker.
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
}
//Whether the animation starts.
bool currentlyAnimating = false;
//Indicate if update the animation.
bool isAnimating = true;
protected override void OnPaintBackground(PaintEventArgs e)
{
if (isAnimating)
{
//Begin the animation.
AnimateImage();
//Update the frames. The cell would paint the next frame of the image late on.
ImageAnimator.UpdateFrames();
}
base.OnPaintBackground(e);
}
//This method begins the animation.
public void AnimateImage()
{
if (!currentlyAnimating)
{
ImageAnimator.Animate(this.BackgroundImage, new EventHandler(this.OnFrameChanged));
currentlyAnimating = true;
}
}
private void OnFrameChanged(object o, EventArgs e)
{
//Force to redraw the form.
this.Invalidate();
}
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("alala");
}
}
This is a similar thread: http://social.msdn.microsoft.com/Forums/en-US/winformsdatacontrols/thread/0d9e790e-6816-40e7-96fe-bbf333a4abc0/.
To disable a form, we can set the Enable property of the Form to false.
Let me know if this helps or not.
