Running code from text file.

[OuTLawZ-GoSu]

I know there is a way to get a code for a certein object from a text file, I just forgot where I saw that infomation. How can this be done?

Also: Is there a way to run 1 line of code from a textbox?
Ex:

'Textbox text:  Msgbox "Sup", vbOkonly 
Private Sub Command1_Click()
       'runcode from textbox"
End Sub
