InputQuery

function InputQuery(const Caption, Prompt string; var UserValue string):Boolean;

The InputQuery function displays a simple dialog with the Caption and Prompt message provided. Prompts the user to enter data in a text box in the dialog. If the user presses OK, the entered data is stored in the UserValue variable and the return value is True. If the user cancels the dialog, the return value is False and all entered data is lost.

Use to prompt the user for simple data such as name.

Example:
var

 valueName : string;

begin

 repeat
   if not InputQuery('Test program', 'Please type your name', valueName)
   then ShowMessage('User cancelled the dialog'); 
 until valueName <> ;

 ShowMessage('Hello '+valueName);

end;
