MessageDlg produces an error when is inside an application datamodule

[nickosl50]

Hi,

 

I try to put the following code  

 

MessageDlg( 'Cannot Delete record' , mtWarning, [mbOK]);

 

in a Application DataModule but code does not build and I get the error 'Undeclared identifier MessageDlg'

 

If I place the same code in a TUniFrame there is no such error 

 

 

I would be grateful if someone can give me a clue of what I done wrong.

 

 

Thank you very much
