Note: While Flash has these advantages over applets, there is more to the story. There are things that you can program in java that just can't be done with Flash. But since the focus here is Flash we will not go into the details.
In order to create Flash movies you need a to buy the Flash program. It is developed by Macromedia and the latest version is Flash Mx.

You can click here to compare actual prices from different online stores.
It should be emphasized here, that buying the Flash program is only necessary for Flash developers.Anyone that has the free Flash plug-in /Active-X installed with their browser can view flash movies.

Once you've installed the Flash program, you should start by completing the 8 lessons that come with it.

• Introduction
• Drawing
• Symbols
• Layers
• Type
• Buttons
• Sound
• Animation

To run these lessons: start Flash then click Help in the top menu and choose Lessons.This will teach you the very basics of the Flash program.

Flash Embedded in HTML:
After creating a Flash movie you choose File > Save As from the top menu to save your movie. Save the file as "Somefilename.fla".
To embed the Flash movie you just made into an HTML page, you should go back to your Flash program and do the following steps:
Step 1
Choose File > Open. Open a Flash movie you have created.
Step 2
Choose File > Export Movie.
Step 3
Name the file "somefilename.swf". Choose the location where the file is to be stored (in your Web folder). Click OK.
Step 4
Open the HTML page where you want to insert your Flash movie. Insert this code:
<object width="550" height="400"><param name="movie" value="somefilename.swf"><embed src="somefilename.swf" width="550" height="400"></embed></object>
Note: This is the minimum code you need to embed a Flash movie in a browser. A broken icon will appear on the Web page if the user does not have the Flash plug-in installed.
Note: In the code above there is both an <embed> tag and an <object> tag. This is because the <object> tag is recognized by Internet Explorer, and Netscape recognizes the <embed> tag and ignores the <object> tag.
Step 5
Type in the address of the HTML file in your browser and look at your first Flash movie.
Let the Flash Program do the Work:

The code above is the absolute minimum code to embed Flash movies in HTML pages. It is not recommended to use the minimum code. There should be a few more attributes added:

• classid is an attribute to the <object> tag. It tells Internet Explorer to load the ActiveX plug-in if it is not installed
• pluginspage is an attribute to the <embed> tag. It displays a link to the Shockwave download page if Netscape does not have it

The Flash program can add these attributes for you:
Step 1
Choose File > Publish. Flash will now create the <object>, <param>, and <embed> tags for you. It will also create the classid and pluginspage attributes.
Step 2
Open the HTML document that Flash created, view the HTML source and copy the code into your HTML page where you want your Flash movie.
Step 3
Be sure that you have the "somefilename.swf" in your Web folder.
Step 4
Type in the address of the HTML file in your browser and look at your first Flash movie.

Tweening comes from the words "in between".
With Tweening you can go from one keyframe to another and specify changes in the animation and let the Flash program create the frames in between.
Example:

In this example you will learn how to make an object move across the screen.
Example
Step 1
Create a small circle to the left in the Stage area. Do this by selecting the circle tool from the left toolbar. Draw the circle in the Stage area.
Step 2
Select the Arrow tool from the left toolbar. Double-click on the circle to select it.
Step 3
Now we have to convert the circle to a symbol. When the circle is converted to a symbol we can create instances of the circle. From the top menu choose Modify > Convert to Symbol. Name the symbol "Ball", and select OK.
Step 4
Go to Frame 10 in the Timeline. Do this by clicking the gray field below 10. Then right click in this field. Choose Insert Keyframe. Keyframes appear as circles in a frame. This operation duplicates the image.
Note: A keyframe specifies changes in an animation. You create keyframes at important points in the Timeline and let Flash create the frames in between.
Step 5
Select the circle and move it to the right a couple of inches.
Step 6
Click on the Timeline any place between Frame 1 and Frame 10. Then right click and choose Create Motion Tween.
Step 7
Choose Control > Test Movie from the top menu to test your Flash movie.

With Motion Guide Tweening you can move an object from one location to another along a specified path.
Example

In this example you will learn how to draw a path an object should follow.
Example
Step 1
Choose Window > Common Libraries > Graphics. Select the image you want to use. In this example we have used a blue mouse.
Step 2
Click on the image and drag it outside the left edge of the Stage.
Step 3
Go to Frame 40 in the Timeline. Do this by clicking the gray field below 40. Then right click in this field. Choose Insert Keyframe. Keyframes appear as circles in a frame. This operation duplicates the image.
Step 4
Click on the Timeline any place between Frame 1 and Frame 40. Then right click and choose Create Motion Tween.
Step 5
Right click on Layer 1 (Click on the layer name, where it says "Layer 1"). Choose Add Motion Guide in the pop-up menu. The Flash program will now insert a motion guide layer on top of layer 1. Motion guide layers are used to draw lines an animated symbol should follow.
Step 6
Click on the Motion Guide Layer to make sure it is the active layer (Click on the layer name, where it says "Guide: Layer 1").
Step 7
Click on the Pencil tool in the left toolbox. Set the Pencil Mode to Smooth (in the Options section of the left toolbox).
Step 8
Draw a line. Begin on the image and draw a line to the other side of the Stage.
Step 9
Go back to Frame 1 in the Timeline. Click on the Arrow tool in the left toolbox. Select the "Snap to Objects" button in the Options section of the left toolbox.
Step 10
Place the image with its center on the beginning of the motion guide (the black line you have drawn with the Pencil). The center of the image shows as a +. A black circle appears when the image is snapped to the motion guide. Release the mouse button when the image is snapped to the guide.
Step 11
Go to Frame 40. Place the image with its center on the end of the motion guide.
Step 12
Choose Control > Test Movie from the top menu to test your Flash movie.
