Delphi window

[question]

Thanks for your reply,i am going to try it out
actually i am new to Delphi, therefore i have another question, i have read some tutorial to understand the difference between procedure and function, but still now i am not so clear. for example ,i have seen that, the Show is a procedure whereas ShowMdal is a function, It would be so kind of you, if you tell me the difference between them, Thanks in advance.
