Is there a LabTalk or OriginC technique for assigning the contents of a notes window to a string variable? Alternatively, can you save the text to a file? (I know how to assign the contents of a text file to %Z.)

Hi Mike,
You can directly access the text in a notes window in Origin C:
void dd(string strNoteWinName)
{
Note noteWin(strNoteWinName);
string strNoteText = noteWin.Text;
printf("Contents of note window: %s\n%s",strNoteWinName, strNoteText);
}

Hi Mike,
You can use the Save -n LabTalk command to save Notes windows as text files.
Eg. Save -n [NotesWindowName] "%YDP\DP-DebugTrace.TXT";
Hope this helps,
Craig

Let me ask again because I want to manipulate and extract text from a Notes window.
Isn't there a LabTalk (not C) command without the detour of writing and reloading a file from disk?
Why isn't there anything straightforward like %Z=NotesWindow!text$; ???
May be I should think about switching to Origin C...?
Is there anywhere a good tutorial (a better one than the LabTalk manual for LabTalk?)
Thanks, Tilman.
By the way how do you store a text file from disk into %Z ? (with LabTalk)

LabTalk interpreter converts %Z etc into actual text before making assignment '='. The assignment by the interpreter has a limitation on the total length of the statment, so sooner or later, problem will occur. I am trying to explain that LabTalk was not intended as a programming environment, and various limitations prevent LabTalk from being such.
Origin C, on the other hand, is a true programming language and since Origin C codes are compiled, such that errors in the code can be checked first by the compiler to prevent unintended results, which is quite often observed with LabTalk.

Hi CP,
OK, I understand... in the longterm I should better switch to Origin C.
But do you know the way how Mike assigns a text file to %Z in LabTalk?
This should also work for me for the time being.
Thanks, Tilman.

Hi Tilman,
You can read a text file with the LabTalk file utilities module (FUM), but I think I was talking about an Origin C method above. Probably using stdiofile. It reads the file a line at a time and you could tack each line to the end of %Z. The FUM method is essentially the same.
...Actually, the easiest way to read a file into %Z is with a combination of LT and OC methods.
1. Open the file into a Notes window with LT's open -n.
2. Read Notes1 with the following OC function.
string ReadNotes(string strNoteWinName)
{
Note noteWin(strNoteWinName);
return noteWin.Text;
}
The labtalk script would look like this...
open -n filename Notes1;
%Z=ReadNotes(Notes1)$;
...Notice the correction to argument of the ReadNotes function.

Hi Mike,
thanks for your comments. Since I haven't dealt with Origin C your solution is not yet that simple to me.
By the way, I thought, I had a simple and pure LabTalk solution:
Just import your text file into a worksheet and say that 9999 lines are the header. After import you can find the text in %Z.
However, obviously it seems that Origin does not allow you to import a pure text file into a worksheet.
Error: file.txt does not seem to consist of ASCII data.
What a pitty. As usual, it could be simple but then it doesn't work.
Again, it seems that I really have to learn Origin C to get simple straightforward tasks done.
Thanks anyway, Tilman.

Hi Tilman,
Once your comfortable w/OC I think you'll find that more and more tasks will become simple and straightforward. Other than learning a whole new suite of functions there are (IMO) only two things you'll need to get over when stepping from LT to OC...
1> Stricter syntax (don't abbrev., watch out for caps, etc).
2> All variables must be declared before they can be used. This can still be a PITA for me at times, but the rewards have been worth it so far.
This task (reading text file) might be a good place to start.
