Interrupt main app, while executing control

In fact, I was missing a line code! Application.DoEvents(); After searching a little more in the net, I found a post that contained an excelente alternative to the ImageAnimator, but it was in VB; It already contained a way to delay the real frame delays. Remember, this code is only to execute an animation of a GIF synchronously (if think this is the way it's written), since ImageAnimator, when running, proceeds animating the GIF in background. This is the "convertion" to C#.. Hope it may be usefull some day for someone who needs (like I did): // Inicializa variáveis this.contFrames = 0; // Conta número de frames this.numFrames = gifAnimado.GetFrameCount(new System.Drawing.Imaging.FrameDimension(gifAnimado.FrameDimensionsList[0]))-1; // Variáveis que captam o delay entre os frames int propertyTagFrameDelay = 0x5100; // Tag com o valor da propriedade do delay PropertyItem propItem = gifAnimado.GetPropertyItem(propertyTagFrameDelay); // Capta a propriedade byte[] bytes = propItem.Value; // Guarda num array os bytes correspondentes ao valor do delay // Cria um array de inteiros com os delays entre os frames int[] delays = new int[numFrames]; // Preenche-o for(int i=0; i
