virtual void CBCGPEdit::OnCalculatorUserCommand ( CBCGPCalculator *  pCalculator, UINT  uiCmd  )

protectedvirtual

Called by the framework when a custom calculator command should be executed.

You have to override this function in a derived class in order to process custom calculator commands. You specify these commands when calling EnableCalculatorButton().

uiCmd contains a command ID which is assigned to a button. Command IDs are assigned automatically starting from CBCGPCalculator::idCommandUser and conform to the order of strings you passed in the string list when called EnableCalculatorButton().

Parameters

pCalculator	Points to a calculator control whose command is executed.
uiCmd	Specifies the command ID.

lstCommands.AddTail("Cos");
