Custom MsgBox via UserForm, startup position and resizable

After searching a lot for a means to define the startup position for a userform, I developed a custom message box via a userform and I would like to share it here.
It also allows a lot more characters to be displayed and has a bit of emulation for the button styles that are available with the built-in MsgBox.

All the code for the custom MsgBox is in a UserForm module and for an example of usage, a worksheet with a button and a regular module is also included.

Edited to attach the Excel file after bumping the Enter key prematurely.
