Hi,
does anybody know how to clear a notes window?
When I open a new data file
open -n FileName NotesName
the datafile will be appended (and not overwritten what I'm looking for).
Of course, I could delete and create the notes window again and again...
loop (i,1,1000) {
win -n notes TempNotes; // create notes window;
open -n Data$(i).txt TempNotes; // import text into notes window;
... do some operations and extraction on it...
win -cn TempNotes; // delete notes window without prompting;
};
This leads to flickering windows and probably slows everything down. OK, it's not that too bad but I just thought that there is something like ClearWorksheet wksName.
Thanks, Tilman.

If you are using version 7 and Higher the following OriginC function should do the trick ...
bool clear_note_Window(string NoteWinName)
{
Note nWnd(NoteWinName);
if (nWnd)
{
nWnd.Text="";
return (true);
}
return (false);
}

Hi rlewis,
your suggestion works fine. Although there seems to be no improvement in speed (as I was hoping). Maybe I have to try to hide the window somehow during import, with the win -o {} command?!
Thanks, Tilman.

The following OC program will read 100 origin.ini files and append them all into a single note window (nwToKeep). On my computer it took 17 sec to execute.


void test()
{
	Note nwToKeep;
	nwToKeep.Create();
	
	for(int ii = 0; ii < 100; ii++)
	{
		Note nwTemp;
		// can replace with you real file here
		string strFile = GetAppPath() + "origin.ini";
		//
		nwTemp.Create(CREATE_HIDDEN, strFile);
		string strText = nwTemp.Text;
		if(strText.GetLength() > 0)
		{
			nwToKeep.Text += "******\r\nFile" + (ii+1) + ":" + strFile + "\r\n******\r\n";
			nwToKeep.Text += strText;
		}
		nwTemp.Destroy();
	}
}
