Macro to Run from Command Button

I have a macro (module) made in excel, I have also created a VB Project as I want a GUI to get certain variables from input that can be passed to the macro. Giving it more functionality as the msgbox available wont suffice. Basically i have some Check box values, and two dates to pass to the macro (module), then execute the macro by clicking a command button. How would i go about this?

Hi
Is it possible to convert your VB Project to an ActiveX Control or a Librariy?
where you can use as a Reference in your Excel VBA ?

Alternatively, create a Userform in VBA and put the code in there (which may be some work, depending on how much code you have). Then you can run the entire thing through Excel.
