Remove extra file contents / Set End of FileHello All;
I have an application which needs to read and write to/from text files. The Config VIs do not give me what I need, and so I am using the File I/O (Open File, Close File, Read Text File, Write Text File) and Adv File Functions (Set File Position). My general flow is this:
Open File --> Read from Text File (Use Spreadsheet String to Array to itemise everything) --> Manipulate the String Array --> Set File Position = 0 from Start --> Write to Text File --> Close File
Having said that, if my reworked string array is shorter (i.e. smaller index) than my original, when I write to file, not everything is replaced. Basically, it only replaces the exact number of characters, if you will, that it needs to. See attached text example (in this case, the !end is listed twice...)...
Is there a way to set the End of File (eof) such that the file ends immediately after I write information? Is there a way to "empty" the file immediately before writing? I suppose an alternative would be to write to a temporary file, and replace the original file with the (slightly smaller) temporary file, but I'd rather only use the single file (if possible).
Anyway, any help would be appreciated!
Thanks in advance,
D. J. Hanna

appending the contents of multiple text files into 1 fileHi,
is there a simpler/more idiomatic way to append/join the contents of
multiple text files into 1 file?
this works, but i'm trying to see if there are more succinct methods.
thanks!

Append a file to an existing fileHi there
I am wondering if there is a simple command in Tcl that I can append a
file to an existing file, or combine two files into one file ?
Thanks for the help.

Here's one way...
- [open] fileA in append mode
- [open] fileB in read only mode
- [read] the contents of fileB and write it to fileA using [puts]
- [close] both files
So, the man pages on [open], [read], [puts], and [close] should give you
all you need.

Filtering files in GetOpenFileName by file contentIs it possible to extend the GetOpenFileName dialog so that it will
filter by file CONTENT as well as filename extension?
For example, so that it will list *.AVI files, but only those
containing DV data.
Or is there another way to do this?
Thanks
I took a quick look at the documentation and it says to set
lpfnHook and OFN_ENABLEINCLUDENOTIFY and respond to the
CDN_INCLUDEITEM message.

Writing contents of an external file to another external file?Hi,
I'm currently working with the ledmac package that I've modified
somewhat to meet my needs. Ledmac is used to create critical endnotes
and (in somewhat simplified terms) it writes the endnote info into an
external file (called \jobname.end) and when a \doendnotes{X} command
is called, it closes that file and places an \input{\jobname.end} into
the root document. I have created also another file (called
\jobname.eaa) in which similar sort or endnote info is written.
The problem is that I would like to periodically, first, write _the
contents_ of \jobname.eaa into \jobname.end (and then empty .eaa to
receive more info, which works ok): essentially to have a command that
periodically "dumps" the contents of .eaa file to the .end file. Ho
could I do this? I have tried many things and searched this group, as
well as a few (La)TeX books but, alas, to no avail.
I can of course simply make the package to periodically write
"\include{\jobname.eaa}" into the .end file, but this is not
desirable, since I don't want the entire, final .eaa file written to
those places, just the contents the .eaa file has _accumulated until_
I give the command to write itself into .end.
I have been thinking about a TeXnique to somehow save, or create
placeholder tokens for the endnote info that now goes into the .eaa
file and then just periodically collate and \immediate\write those
tokens to the .end file, but I'm not at all sure how to do this.

File Contents Won't Update Until File is OpenedHey,
I ran into this problem before, but cant remember if/how I solved it. Anyways, I'm overwriting a file (objfun.m) based on what the user inputs. I'm using:
fid=fopen('objfun.m','w');
A bunch complex parsing stuff hapens here....
fclose(fid);
Then the new contents of objfun.m are read and used in my program. The problem is objfun.m is not actually changed unless I manually open it. What happens is when I read objfun.m I still get the old contents. If I double click it (manually opening it),I see the new stuff is there. Now, by opening it, it has been changed and I can read the new contents. It's as if the file is not properly updated for some reason until it is manually opened. Is there way to fix this or a workaround?
Thanks
Remembered the solution. I must use clear functions to update the contents. Thanks.

SYSMAN output to file appends the contentsIn a command procedure, I used DEFINE/USER to redirect the output of
SYSMAN to a file. This works fine. However, the output is APPENDED to

new version is created. Why the difference? Bug or feature?
Removing the /USER gives the "expected" behaviour. Discuss.

Open a file from remote Windows and use the content in the file locallyhi,
I am new here, i have been google around for so long on this issue so i
decided to stop by and bother you guys.
I use tcl and Expect on a Redhat linux system to remotely telnet to a
windows system to run some test. end of the test, a file called
"log.dat" is generated. then i will need to analyze the number of
errors in the log.dat(basically all text) to decide what the windows
system should do next.
so here comes the question, how do i process the log file, so i can use
it locally on Red hat to do a check? (my idea is to store the content
of log.dat as a variable locally, then use regular expresstion to check
it)
newbie here, want to get it done in a quick and dirty way.

Debug.Print lineBuf

Generic file I/O error, the file is not a valid labview fileHi,
I have created a project in LV 8.0. Now I am getting the following error when I try to open it...'Generic file I/O error, the file xxxxx.vi is not a valid labview file.' I have tried to open all the subvi's used in my application and I am able to open all of them.
I found that this condition may occur if the hard disk is full. So I tried to open my vi from another PC but I am getting the same error everywhere. What am I supposed to do ?? Please help me out if anyone has a solution to this...

Hi Mike... Thank you for your reply...
I get this error when opening the main vi in my application. I can't recall anything which may have corrupted the file. The earlier version of the main vi of which I had saved a copy does not give any problems while opening. I had made many changes in the next version of my application which is lost now... Do you think that the file may be corrupted? Is there no way to retrieve it?
I do have a system running LabView 8.2 and I have tried to open this file with that version. But I am still getting the same error.

That's interesting, I've found out that it's the browser that's hiding <?php
?> tags within .phpx pages. Probably to avoid short tags scripts (on a
server that doesn't allow them) from getting leaked by visitors who don't
know about this browser trick, until the dev' realizes his error.
Not a good thing, IMO; dev's should take care, themselves, and it's still
not secure since the hidden string is still in the rendered source. And now
we don't know how ...
Reg: Copy records from one file to another based on contents of a third file.Hi,
