yo MathGroup,
I have a serious problem with the NotebookSave[] Functions;
I am using Mathematica 3.0;
Anytime I call them, I get a "Why the beep", telling me that there was some
problem with the Notebook & that I should close the file & open it using
OpenSpecial;
the function seems to destroy the notebook, cause some cells turn white,
like they were not there;
it even crashes mathematica completely (I have to kill it via Taskmanager)
this behaviour is reproducable and not only appearing on my Mathematica
installation, because I have already sent the following code to a
mathematica expert, he ran the code and told me tha he had'nt seen anything
like it before;
---
Module[{nb=InputNotebook[],nb1},
NotebookSave[nb];
NotebookSave[nb, "MurphyABC"];
NotebookClose[nb];
nb1 = NotebookOpen["MurphyABC"];
NotebookFind[nb1,"CellTagName", All, CellTags];
NotebookDelete[nb1];
---
the problem is that Mathematica only gets til the NotebookSave[] functions,
and the shows the behaviour I described above;
what I want to do with the code is to:
- somehow produce a copy of a notebook
- find all cells with a certain cell-tag in the copy
- delete all the cells with the cell-tag
a previous attempt was to get the copy using this code:
---
Module[{nb=InputNotebook[],nb1},
nb1=NotebookPut[NotebookGet[nb]];
NotebookFind[nb1,"CellTagName", All, CellTags];
NotebookDelete[nb1];
---
the notebook to copy is about 900 KB;
the problem with this code is that it takes about 126 seconds on my PC (100
MHZ, 24 MB RAM, NT4.0);
even on a 200 MHZ Pentium with 64 MB RAM, this code still takes 25 seconds,
which is still way too slow;
the bottle neck is the NotebookGet/-Put functions; the finding & deleting
of the cells takes (on my PC) about 4 seconds;
my questions are:
- does anybody know a way to copy a notebook in memory (like with
NotebookPut/-Get)?
AND/OR
- does anybody know a workaround for the NotebookSave bugs?
I hope you understand the babbling above and can help me;
Thanx in advance
