TString? I assume you mean a list of string so that's a TStringList.

Use the following :

Procedure MyTest;
Var
  MyStrings:TStringList;
procedure TForm1.Button3Click(Sender: TObject);
Begin
  MyStrings:=TStringList.Create;  {Create the TStrings object}
{Do your job}
{for example :}
  MyStrings.Clear;
  MyStrings.add('test');

  MyStrings.Free; {destroy the TStrings object and free memory}
End;

I will assume by TString you really mean TStingList???
useing a string is as simple as doing
Var
  MyString : string

MyString := 'My Big Ass String';

To use a String List you need to do a bit more

Var
  MyStringList : TStringList;

To Assign a value do this

MyString := TStringList.Create;
MyString.Add('My Big Ass String');

Then When you are done with it do a
MyString.Free;

Hope this is what you needed.

I mean TStrings. (I want to make a text for a RichEdit dynamically and store it to the RichEdit.Lines property)

Our Dev teams are like yours. They’re continually cranking out code for new features/bugs fixes, testing, deploying, testing some more, responding to production monitoring events and more. It’s complex. So, we thought you’d like to see what’s working for us.

As far as i know, you need to use a TStringList and when you want to put the strings to the TRichEdit, then use RichEdit1.Strings:=MyStrings;
You can't use a TStrings object directly (In Delphi help it is written : "To maintain a list of strings outside of a control, use a string list object (TStringList).")

what I think you really mean it a TStringStream this is what one normaly uses to get the Rich text proporties out of a RTFEdit.  This is because if you say
var
 MyFattyString : string
begin
  MyFattyString := RTFEdit1.Text
end

MyFattyString is just a string of text with none of the formating stuff in it.

so I think you want to do something like this

var
  MyStream : TStringStream;
begin
  MyStream := TStringStream.Create('');
  RtfTextEdit.SaveToStream(MyStream);
  MyDB.FieldByName('CPNote').AsString := MyStream.DataString;
  MyStream.Free;
end;

then when you want the text to go back to the RTF you can use it as a plane old string then
    RtfTextEdit.Text := MyDB.FieldByName('CPNote').AsString;


Hope this is what you need because you'll have to put the points to 100 before I come back in here :)

var T : TStringList;

  T:= TStringlist.Create;
  T.clear;
  T.add('Hallo');
  T.add('Test');
  Form1.RichEdit1.text:= T.text;

That worked for me. I wanted to create some text and let it display in a RichEdit.
The error I was getting was because I did the above stuff in the onCreate handler of Form2.
Now that I put it into Form, it works
