When you run the self-extracting compressed file, the following files are expanded in the Joystick Sample Project directory:

Form1.frm (7Kb) - the main form of the project.

Joystick.vbp (1Kb) - the project file.

Joystick.vbw (1Kb) - the workspace file.

Module1.bas (7Kb) - the module containing the function, user-defined type and constants declarations.

Readme.txt (2Kb) - you are currently reading this file.

How the Sample Works

The joyGetDevCaps function is used in the form load event to determine if a joystick is connected to the system. If the function is successful, the form is redrawn with new controls to display the capabilities of the joystick. These capabilities are stored in the members of the JOYCAPS user- defined type variable. A timer control is used to poll the joystick's position. The current position is determined by the successful results of the joyGetPosEx function. The members of the JOYINFOEX user-defined variable type contain the joystick position information. This information is displayed in text boxes in the form.
