You're right, of course. I just thought it would be fun to process the mask at compile time :) It turns syntax errors in the mask into compile errors. It also greatly increases your chances for ICE's under VC 6! > > Also, I do like your idea of getting rid of static text controls. Thanks! My motivation for the above example was to show that you can also get rid of other controls once you incorporate data exchanging into the gui_manager. The gui_manager<> template is sort of like a rule in Spirit. It lets you put a big nasty template expression into something easier to type. In this case you can get/and set employee objects: gui_manager<employee> gui = make_gui(); employee e; gui.get(e); //reads from the controls into the employee structure gui.set(e); //writes to the controls from the employee structure. The above snippet was supposed to illustrate that you can get rid of more complex controls than just a static text control. Here I defined inline a masked edit, a combo box, and a plain text edit box. I've got some other functions to implement other GUI idioms, like tying the enabled status of a group of controls to a check box, an enumeration to radio buttons, etc... You might notice that there are no Win32 specific objects mentioned above. My library is not ready for boost, but it is in production. It will be running the payroll maintenance system for over 800 restaurants soon. I'd be surprised if there were over a few hundred lines of code (in the GUI) for a fairly large and complex application.
