[SecurityPermissionAttribute(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.UnmanagedCode)] [SecurityPermissionAttribute(SecurityAction.InheritanceDemand, Flags = SecurityPermissionFlag.UnmanagedCode)] protected internal virtual bool ProcessCmdKey( ref Message m, Keys keyData )
- Type: System.Windows.Forms.Message
A Message, passed by reference, that represents the window message to process.
Return ValueType: System.Boolean
false in all cases.
This method is called during message preprocessing to handle command keys. Command keys are keys that always take precedence over regular input keys. Examples of command keys include accelerators and menu shortcuts. The method must return true to indicate that it has processed the command key, or false to indicate that the key is not a command key.
The base-class implementation of method returns false in all cases.Notes to Inheritors
When overriding the method in a derived class, the method override should return true to indicate that it has processed the key. Derived classes will seldom, if ever, need to override this method.
