TCustomMemo.Lines Property

Contains the individual lines of text in the memo control.

Pascal

property Lines: TStrings;

C++

__property TStrings Lines;

Description

Use Lines to manipulate text in an memo control on a line-by-line basis. Lines is a TStrings object, so the TStrings methods may be used for Lines to perform manipulations such as counting the lines of text, adding new lines, deleting lines, or replacing lines with new text.

To work with all the text at once, use the Text property. To manipulate individual lines of text, the Lines property works better.

Note: Although Lines is implemented as a TStrings descendant, it does not implement the support for associating objects with the strings in the list.

C++ Examples:

Copy Code

/*
This example uses a button and a memo control on a form.
When the user clicks the button, the content of the specified
file is loaded into the memo, and the fifth line of the file
is written across the top of the form.
*/
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  Memo1->Lines->LoadFromFile("../readme.txt");
  Caption = Memo1->Lines->Strings[4];
}
