Title: [solved] RichMemo - How to safe it into a file?
Post by: Nicole on July 11, 2022, 08:23:28 pm

TRichEdit from Delpi knows "TRichEdit.SaveToFile('myFile');

and .LoadFromFile.

How to do this by Lazarus and RichMemo?

.LoadRichText
.SaveRichText

and it needs a TFileStream as a parameter

OR there RichMemoUtils unit with
LoadRTFFile and SaveRTFFile functions

thank you for the answer.
Please can you do it one by one for stupid?

if there is a RichMemo1
and a
c:\myFile

How to connect them?

(I tried a lot, but ended up with error messages about strings, files and streams, filestreams and datastreams "no compatibel')

Argh. I missed those in the other topic from TS.
I gave there a class helper for TRichMemo.LoadRTFFromFile.

Always show code and error messages.

Did you include RichMemoUtils in the uses and tried RichMemo1.LoadRTFFile()?

yes.

uses

LazFileUtils, RichMemoUtils, VpData;

================
code

self.RichMemo_Notizen.LoadRTFFile(Pfad + 'RichMemo.txt');

============
compiler

unit_notizen.pas(153,26) Error: identifier idents no member "LoadRTFFile"

(PS pls explain this to me, because I am not sure, how to do better: 'Argh. I missed those in the other topic from TS.
I gave there a class helper for TRichMemo.LoadRTFFromFile.' start explanaition by: What does TS mean? thx.)

self.RichMemo_Notizen.LoadRTFFile(Pfad + 'RichMemo.txt');

The LoadRTFFile from RichMemoUtils isn't implemented as class helper (like I did in the other topic) but as ordinary function.
(sorry for the confusion)

So you can just use

Code: Pascal [Select][+]

LoadRTFFile(Pfad + 'RichMemo.txt');

TS stands for Topic Starter (you :D). Sometimes also OP (Original Poster) is used.
