<h2>Introduction</h2>
<p>This is a simple presentation programme in which you can add slides, text, images and also assign simple animations to them.
<h2>Features of classes </h2>
<p>The code contains two user controls i.e textcontrol.cs, pictureControl.cs. There is also a class for dotted line by which you can add dotted lines, you can also determine its thickness , distance between the points and so on.
<p>
<h2>Using the code</h2>
<p>There are a number of classes in it.
<p>One of the main class is
MainObject.cs.
<pre> public MainObject()<br> {<br><br> }</pre>
<p>There is also a class for dotted line. </p>
<pre>
//
// public void drawLine(Graphics g)
{
Pen pen = new Pen(Color.Gray, thickness);
int <code>dis </code> = (int)Math.Sqrt((double)((x2 - x1) * (x2 - x1)) + (double)((y2 - y1) * (y2 - y1)));
int <code>end </code>=<code> dis</code> / (1 * length);
double <code>rad </code>= <code>angle</code> / 180 * Math.PI;
for (int i = 0; i < <code>end</code> - 1; i += <code>distance</code>)
g.DrawLine(pen, (float)(x1 + ((i * length) * (float)Math.Cos(rad))),
(float)(y1 + ((i * length) * (float)Math.Sin(rad))),
(float)(x1 + ((i + 1) * length * (float)Math.Cos(rad))),
(float)(y1 + ((i + 1) * length * (float)Math.Sin(rad))));
}
//
</pre>
<p>and for animation
<pre>
if (distance(tmpTextControl.X1,
tmpTextControl.Y1,
tmpTextControl.X2,
tmpTextControl.Y2) > 5)
{
//for animation
if (tmpTextControl.AnimationStarted)
{
tmpTextControl.Show = true;
tmpTextControl.X1 += (int)(
9.0 * Math.Cos(tmpTextControl.Direction));
tmpTextControl.Y1 += (int)(
9.0 * Math.Sin(tmpTextControl.Direction));
}
}
else
{
if (i < customControl[currentSlide].Length - 1)
customControl[currentSlide][i+1].AnimationStarted = true;
}
</pre>
<p>
<h2>Using the application </h2>
<p>You can add a control(i.e picture box or text box) from the insert menu and then click on the screen to place it there. For animation you have to select the control and then go to the animation menu and select the desired animation. A control can be edited by double clicking on it. <!------------------------------- That's it! --------------------------->
