GIF Animation not working in Windows Form

Question

I have 2 WinForms

Form2 uses Infragistics ultraTabControl. On Tab Changing im Showing Form1.

In Form1

I have a PictureBox assigned with animated GIF

In Form2

I am displaying Form1 like this.

Form1 frmOne=new Form1();
frmOne.Show();

Problem

GIF is not playing animation.

Answer 1

Make sure you have your image in the image property NOT THE BACKGROUND IMAGE PROPERTY. That's the mistake I made

Answer 2

It is working fine for me. I have just dragged a new pictureBox on form and setting image property at Form_Load() event and showing GIF animated.

I did same as you on button click:

  TestForms.NavBarTest newForm = new TestForms.NavBarTest();
            newForm.Show();

At my Test Form:

private void NavBarTest_Load(object sender, EventArgs e)
        {
            pictureBox1.Image = NavronChartControl.Properties.Resources.url;
        }

Note: If your picture box is disabled then it will not animate the Gif

Answer 3

Solved

My current Thread is busy to Play GIF Animation.

I tried So many ways like Application.DoEvents(); etc. But every thing can't helped me.

The answer in the following Question, which uses Threading is a very great working idea.

Thanks for every one.

Answer 4

The best way to achieve it is to run the animation in an async task, but accordingly, some limitations are possible to do that on windows form using:

System.Threading.Thread.Sleep(int milliseconds).

My splash view is displayed with a gif (loading)

e.g.: In your constructor,

public partial class MainMenu : Form
{

    private SplashScreen splash = new SplashScreen();

    public MainMenu ()
    {
        InitializeComponent();

        Task.Factory.StartNew(() => {
            splash.ShowDialog();
        });

       Thread.Sleep(2000);
   }

It is imperative to put the Thread.Sleep(int) after starting a new one, don't forget that every action you did on this thread needs to be invoked, for example:

    void CloseSplash()
    {
        Invoke(new MethodInvoker(() =>
        {
           splash.Close();
        }));
    }

Now your gif should work!

Answer 5

This question has already raised before. Though the approach is different but the questions concept is the same

Source project where you can use Code Project

I guess that will help you out

Answer 6

If none of the previous answers work for you, another idea is to refresh the image tag or write it on the fly with jQuery.
In my case I needed to show an animated GIF when a button on the form was clicked. Previously it would show up but not animate. I just added a jQuery event when the button was clicked that added the image tag on-the-fly to a div through the parent tag's html() function.

$('.showhidegif').html("<img src='/Content/img/angled-spinner.gif' />");

<div class="col-sm-12 showhidegif"></div>

Worth a shot especially if you're already using jquery on your page.

Answer 7

I had the same issue and came across different solutions by implementing which I used to face several different issues. Finally, below is what I put some pieces from different posts together which worked for me as expected.

    private void btnCompare_Click(object sender, EventArgs e)
    {
        ThreadStart threadStart = new ThreadStart(Execution);
        Thread thread = new Thread(threadStart);
        thread.SetApartmentState(ApartmentState.STA);
        thread.Start();
    }

Here is the Execution method that also carries invoking the PictureBox control:

    private void Execution()
    {
        btnCompare.Invoke((MethodInvoker)delegate { pictureBox1.Visible = true; });
        Application.DoEvents();

        // Your main code comes here . . .

        btnCompare.Invoke((MethodInvoker)delegate { pictureBox1.Visible = false; });
    }

Keep in mind, the PictureBox is invisible from Properties Window or do below:

private void ComparerForm_Load(object sender, EventArgs e)
{
    pictureBox1.Visible = false;
}
