Parameters 

Description 

Sender 

This parameter defines which instance of TJwServerAccessControl is calling the method.  

DesiredAccess 

Defines the access requested by the caller of the AccessCheck function.  

TrusteeName 

Defines the name trustee who is used to make the request.  

TrusteeSID 

Defines the trustee as a TJwSecurityID class who is used to make the request.  

AProperty 

Defines a property supplied to the TJwServerAccessControl.JwIsAccessAllowed.  

Trustee 

Not used. Always nil.  

AccessGranted 

Receives the previous result of the access check. Set to true to grant access; otherwise access will be denied.  

ErrorCode 

Defines an error code that is returned to any caller. Actually an error code of < 0 will raise an EOleSysError exception with a generic message. You can raise your own EOleSysError exception to return any HRESULT value to a COM caller. In this way you can see your custom made error message (good for debugging). However, if you use other exception classes COM callers will receive the HRESULT error E_UNEXPECTED.
