IsIconRegistered Method

Checks whether the specified icon is registered.

Syntax

cbmemdrive.isIconRegistered(iconId, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method checks whether an icon with the specified IconId has been registered. If such an icon has been registered, this method returns true; otherwise it returns false.

Icons can be registered using the RegisterIcon method. Please refer to that method's documentation, as well as the Custom Drive Icons topic, for more information.

The Helper DLL must be installed in order for this method to function correctly. Applications can check to see whether the Helper DLL is installed using the GetModuleVersion method, and install it using the Install method if necessary.
