I have an oracle .dmp file, and no access to a local oracle install..
Is there any way I can read the data or open it in another program to see what data is in this file?
Nope, the .dmp files are generally meant to be read and imported by Oracle's imp tool
If that's it, don't waste your time. DMP files are to be read by
Oracle's IMP utility and nothing else
(you could, of course, use any editor,
but you're close to see nothing useful
in there).

Seems if you have a licensed copy of Toad, you can use the DBA utilities to view the files
The DBA utilities in TOAD has File
Browser that allows you to view export
files. Although I think this function
is only available in a fully licensed
copy of TOAD.

If all you want is a feel for what's in there, open it with Vi or Notepad++ or some other reasonable editor and you can see the DDL statements scattered throughout. A lot of the data will be intelligible as well. However, it IS a binary file, so making a lot of use of it is problematic. Also, if it's huge, the editor you use may not be able to handle it, so you might want to use a pager like less.
That said, can't you download the Oracle Client software and install it? The administrator utilities in there include imp/exp IIRC.

How to parse a OFX (Version 1.0.2) file in PHP?
I am not a developer. What easy tool can I use to make this code run with no code skill or appetence ? web browser is pretty hard to use for non dev guys.
I need this to use the file into Power BI, which accept M code, json source or xml, but not sgml ofx or PHP.
Thanks in advance
Welcome Didier to StackOverflow!
I'm going to try and give you a clue how I'd approach the problem here. But keep in mind that your question really lacks details for us to help you, and I'm asking to update your question with example data that you want to integrate into PowerBI. Also, I'm not too familiar with PowerBI nor PHP, and won't go into making that PHP code you linked run for you.
Rather, I'd suggest to convert your OFX file into XML, and then use PowerBI's XML import on that converted file.
From your linked question, I get that your OFX file is in SGML format. There's a program specifically designed to convert SGML into XML (which is just a restricted form of SGML) called osx. I've detailed how to install it on Linux and Mac OS in another question related to SGML-to-XML down-converting; if you're on Windows, you may have luck by just downloading a really ancient (32bit) version of it from ftp://ftp.jclark.com/pub/sp/win32/sp1_3_4.zip. Alternatively, you can use my sgmljs.net software as explained in Converting HTML to XML though that tutorial is really about the much more complex task of converting HTML to XML/XHTML and will probably confuse you.
Anyway, if you manage to install osx, running it on your OFX file (which I assume to have the name yourfile.ofx just for illustration) is just a matter of invoking (on the Windows or Linux/Mac OS command line):
osx yourfile.ofx > yourfile.xml
to result in yourfile.xml which you can attempt to load with PowerBI.
Chances are your OFX file has additional text at the beginning (lines like XYZ:0001 that come before <ofx>). In that case, you can just remove those lines using a text editor before invoking osx on it. Maybe you also need a .dtd file or additional instructions at the top of the OFX file informing SGML about the grammar of your file; it's really difficult to say without seeing actual test data.
Before bothering with SGML and all that, however, I suggest to remove those first few lines in your OFX file (everything until the first < character) and check if PowerBI can already recognize your changed input file as XML (which, from other OFX example files, has a good chance of succeeding). Be sure to work on a copy of your original file rather than overwriting it. Then come back and update your question with your results and example data.
I'm currently making a personal account manager program and right now I've achieved creating one but there is a visible .accdb file along with the .exe itself. And it is not very safe since the .accdb can just be opened.
Is there anyway to achieve this without having a visible database? Or any secure way in achieving this would be appreciated.
SQL Server Compact Edition supports encryption.

And no, you aren't going to be able to embed it in the .exe unless you come up with a tremendously complex scheme of recompiling the .exe every time the database changes.
You could set the hidden attribute on the database file, though, to try to obscure it. It just depends on whether your goal is to stop competent hackers (which it won't do) or just to stop a user from accidently deleting or renaming it (which it will do). A hidden, encrypted, file would do both.
I recently recovered a 1.5TB external HDD that crashed. The program I used to recover the files was Active Undelete Enterprise, it's excellent. When the files were successfully recovered they were all saved with a .efs extension so files looked like mydocument.docx.efs. At first I thought they were encrypted and needed to be decrypted, I spent 10 mins on it and realized I just need to remove the .efs from the entire filename and the mydocument.docx works perfectly. Problem is now I have over 55,000 files within hundreds of folders where I need to simply remove the .efs after each file. Does anyone know how to do this?
From a command prompt window, navigate to the top level directory where these files reside.
Type the command
DIR /S/B >>filelist.txt
This command will give you a bare format file listing of the current directory plus all nested subdirectories without any extraneous information. The list will be contained in the text file named "filelist.txt" or whatever else you choose to call it. I would then use this text file in a text editor to convert every line of text from, for example,
C:\Users\dlucas\.gimp-2.8\mathmap\file1.png.efs
to
rename c:\Users\dlucas\.gimp-2.8\mathmap\file1.png.efs file1.png
to give a simple example of a file that I just found on my system using this method.
You will need to use a text editor with a columnar editing capability since you have to modify som many files. Old programmer's editors such as CodeWright made this really simple while modern editors such as Eclipse or Notepad++ make this a little more difficult and may require a columnar editing plugin, depending on version. You basically have to make a columnar copy of all of the text in the file, and then paste the copy off to the far right - far enough that a second column of filenames and paths won't overwrite any of the existing file names and paths. You can then use columnar editing features to select and delete the path names of the text in the 2nd column since the rename command requires that the 2nd argument be simply the base filename and extension without the path information. You can use the columnar editing features to prepend every line with "RENAME ". If you attempt to do this without columnar editing features, you will find it slow going!
An alternate way to do this is to use a command formed from a "regular expression" to create the rename command. If you are not familiar with "regular expressions", ask a programmer friend as this is not an easy topic to learn from scratch. If you are familiar with regular expressions, this is probably the simplest way to perform this task. I haven't used them in many years and no longer recall the exact syntax to use or I would tell you myself.
Regardless of what kind of editor you use, the goal is to turn this ASCII file list of paths and filenames into a batch file (simply rename file1.txt to file1.bat when you are finished editing). You can then run the batch file by typing file1.bat at a command prompt.
I have just run into this same problem myself using the same really wonderful tool that you used. I am writing this while waiting for the undelete program to finish. That it restores files with this extra extension seems very anti-intuitive so I will look for an option to make it not do this when it finishes. If I find one, I will post a new answer here that is more specific to this tool. Otherwise, I am going to have rename all kazillion files just as you had to.
You experienced this problem because the disk that you recovered your files to "does not support encryption", according to the Active# UNDELETE documentation. The documentation offers no further explanation of what kind of disks support encryption, etc.
They offer a Decrypt command that restores the file's proper names as a post processing step. Unfortunately, this requires that you "include" each and every file to be decrypted, with no support for wildcards and parsing subdirectories so that is a non-starter, in my opinion given that both of us have hundreds of thousands of files to be renamed.
I did find that by selecting a normal fixed (non-removable) hard drive as the destination of the recovery effort, that the resulting files do not end up encrypted (i.e., they are recovered with the proper file name and extension). I originally chose a large USB based flash drive and the files were stored in their "encrypted" state (not really encrypted, but possibly potentially so and thus they give the .efs extension). Of course, this meant that I had to run the command all over again after switching to a regular hard drive (takes about 16 hours to recover 80GB worth of files due to presence of many sector CRC errors).
After reading (nearly) the whole ebook and taking a look at the API
i am still asking myself how to realize "traditional" web server behaviour with opa.
I understand (at least i believe that) that opa links external resources specified at
compile time into the executable, making them immutable and permament.
But what if, say, i would want to change the stylesheet of an application without recompiling it?
There seems to be a few methods in the stdlib (apidoc) but they are not covering
what i am used to from other programming languages.
A possible solution i could think of is making use of the internal database,
but that looks like a bit of an overkill for something simple like traditional File I/O.
Edit: this blog post explains more about dealing with external resources in Opa.
Long story short: you'll rarely work with external files in Opa.
Let me try to break this down. Opa will indeed embed resources. But for development mode you indeed just want to be able to tweak them (mainly CSS) and see changes immediately. If you compiled your program in a non-release mode then it will support this kind of actions (try --help, below is an excerpt)
Debugging Resources : dynamic edition:
[...]
--debug-editable-css
Export the CSS files embedded in the server to the file
system, so that they can be viewed and edited during
execution of the application
For many other editable&changing resources one would indede use the database.
And if you really need to work with files (again: with Opa you'll need it much less than with traditional web languages) then take a look at stdlib.io and, for advanced use, at BslFile module with bindings to Ocaml functions for file manipulation.
I think this module is for you :
http://opalang.org/resources/doc/index.html#file.opa.html/!/value_stdlib.io
import stdlib.io
my_css = File.content("css/file.css")
I am not seeing some way to write file, but I think if you need to write you should use the db.
But to read I think this is the solution :)
I've always backed up all my source codes into .zip files and put it in my usb drive and uploaded to my server somewhere else in the world.. however I only do this once every two weeks, because my project is a little big.
Right now my project directories (I have a few of them) contains a hierarchy of c++ files in it, and interspersed with them are .o files which would make backing up take a while if not ignored.
What tools exist out there that will let me just back things up efficiently, conveniently and lets me specify which file types to back up (lots of .png, .jpg and some text types in there), and which directories to be ignored (esp. the build dirs)?
Or is there any ingenious methods out there that people use?
Though not a backup solution, a version control manager on a remote server responds to most of your needs:
only changes are saved, not the whole project
you can filter out what you don't want to save
Moreover, you can create archives of your repository for true backup purposes.
If you want to learn about version control, take a look at Eric Sink's weblog, in particular:
Source Control HOWTO, for the basics of source control
Mercurial, Subversion, and Wesley Snipes for the links to articles on distributed version control systems
I use dropbox, im a single developer developing software. In some projects I work out from my dropbox which means they synchronize every time i build. Other projects i copy the source code there my self. But most important is that i can work on all my computers with dropbox installed on them... works for my simple needs
Agree with mouviciel. If you do not want that, consider rsync or unison to efficiently keep an up-to-date copy, be it on the same or a different machine.
