VBA Protected Code

As shown, we substituted the original code within the calculate() function by a call to CallXLSPadlockVBA, a built-in function of XLS Padlock. This function runs the compiled bytecode, which is inaccessible to end-users. However, the calculate() VBA function remains entirely functional, even in the original Excel workbook before the compilation process.

We transferred the original VBA code from calculate() to the VBA Compiler of XLS Padlock directly in Microsoft Excel. Afterwards, the compiled the code. We can now invoke it with CallXLSPadlockVBA({name of the compiled VBA sub to invoke}).
