CplApplet

	long CplApplet(hWnd, wCode, dw1, dw2)
	HWND hWnd;
	WORD wCode;
	DWORD dw1;
	DWORD dw2;

The CplApplet function carries out requests from Control Panel. Control Panel calls this function when the user chooses an icon, such as the mouse icon, to direct the corresponding driver to carry out some action.

A mouse driver that provides a custom mouse-setting dialog box must export the CplApplet function.

Parameters

hWnd

Identifies the Control Panel window. The mouse driver uses the handle as the parent window handle for the settings dialog box.

wCode

Specifies the action to take. If the wCode parameter is 5, CplApplet displays the custom mouse-settings dialog box.

dw1

Reserved; do not use.

dw2

Reserved; do not use.

Return Value

The return value is TRUE if successful. Otherwise, it is FALSE.

Comments

The export ordinal for this function is 6.

If CplApplet returns FALSE, Control Panel displays its standard mouse dialog box. If an error occurs, for example, the mouse driver cannot find or load its dialog box, CplApplet displays an error message before returning the FALSE value to Control Panel.
