AnsiString s = " Hello World! "; s = s.Trim(); // s now contains "Hello World!"
AnsiString s = " "; s = s.Trim(); if (s.IsEmpty()) { ShowMessage("String is empty."); }In this example, we create an AnsiString 's' with only whitespaces. We then call the Trim() function on 's' to remove those whitespaces. We then use the IsEmpty() function to check if the string is empty and show a message if it is. Overall, the Trim function is useful for cleaning up strings and making sure there are no leading or trailing whitespaces that could cause issues in further processing.
