How to use MaskEdit to ensure a correct number input


I am working on a program where I need to be absolutly sure that the number i receive is 11 numbers no more no less.

I have fumbled around with MaskEdit and EDBEditError exceptions, but I am rather uncertain how to use this correctly.

I would like to know if I am all wrong in assuming that I have to use exceptions and how to use them correct.

you can use a mask edit, make the mask
'999999999' ie 11 numbers..

then you can run a check like

if lenght(Maskedit1.Text) <> 11 then
  //handle the fact that the user has not typed in 11 digits!
