LabTalk is limited to 3799 characters when reading long, embedded Note text:
string str;
str$ = col(2)[1]$; // Source of embedded Note
str.GetLength()=;
outputs 3799
Must be some defined buffer limit.
If I don't know the name of the Notes Window (I won't in this application), how can I read the full text?
The GetText method of the Dataset reads the cell as empty (Origin 2015SR2).
The GetCell method of the Worksheet has a similar limit to LabTalk:
// This code reports 3799 characters
string ReadNote(string strSh)
{
Worksheet wks(strSh);
string str;
wks.GetCell(0,1,str);
printf("Length : %u\n", str.GetLength());
return str;
}
Oddly, if this function is called from LabTalk, the string is further truncated to 3071 characters.
So, unfortunately, only if I know the name (and stay within Origin C) can I process the full text:
...
Note nt(strNoteName);
string str = nt.Text;

Hi,
Inside Origin, when get text from a cell in worksheet, the length limitation is 3800(including the terminator '\0'), since in most case, we assume the text in a cell should not exceed this limitation, yet embedded Note is an exception, we may consider to improve that later(provide some API to get embedded Note page name).
