Display a Save As Dialog

A Save As dialog is often presented to allow a user to select a location to save a file to. To display a Save As dialog using AutoPlay Media Studio:

1. Create a Dialog.FileBrowse action. Set the FileOpen property to false:

file=Dialog.FileBrowse(false, "Save As", "c:\\", "All Files (*.*)|*.*|", "", "", false, true);

Note: File is a table. In the above example, multiple file select is not allowed. To access the path returned by the FileBrowse action, use file[1] as a variable. This gets the value from the first position of the table.

2. If you are using the Save As dialog to copy a file from your cd to the user's system, you must use a File.Copy command after the Save As dialog has been displayed:

File.Copy("c:\\example.exe", file[1], false, false, false, false, nil);

Display Text and/or Images with MouseOver Events

Most objects in AutoPlay Media Studio have two events useful for mouseover effects: On Enter and On Leave.

As an example, we will create a button that on mouseover will display an image, and on mouseout will hide the image:

1. Create an image object

2. Set its default visible state to false.

3. Create a button object.

4. In the On Enter event of the button, enter the following script:

Image.SetVisible("Image1", true);

4. In the On Leave event of the button, enter the following script:

Image.SetVisible("Image1", false);

Note: When the user's mouse is over the button, the image object will appear. When the user's mouse leaves the button, the Image Object will disappear.

Tip: To make text appear on a mouseover, follow the above steps, but with a paragraph object instead of an Image Object.
