I have an .net application fully built up for commercial purpose. The application utilizes SQL Server DB to store all the information. If you like specifics of the application, it is a Forex trading application where it stores all the price ranges changes during the day. So all the data is stored in the SQL Server.
Now what I would like to know is how can I know where is the application DB is location and where it is pointing to.
Also application has this feature where we can export the tables that I am viewing to excel file, the way it creates excel files is really "beautiful", would like to know what are the VBA commands that it is utilizing. I suspect this might be a batch file that is being run when we trigger the export option.
The reason I am wanting to know this is,
I want to make this automated, as in everyday at 0600 I would like the export to be automatic and the exported file will have todays date... I can do all the later mentioned tasks, the thing I am having problem is knowing where is the db and the VBA commands.
If my memory serves me right, there was this program that gives u insight in to everything that your computer does.

I am helping out an organization which are planning on changing their members system. Right now their system is developed in Plone and all their data is in a Data.fs file.
Their system is down for the moment and it would take some time and effort to get it up and running.
Is there a way to get the data out from the database into a standard format such as csv files or SQL? Or do they need to get the system up and running beforehand and export the files from "within" plone?
Thanks for your help and ideas!
Kind regards,
Samuel
The Data.fs file is a Object Oriented Database file, and it is written by a framework called the ZODB. The data within it represent python instances, layed out in a tree structure.
You could open this database from a python script, but in order for you to make sense of the contained structures, you'll need access to the original class definitions that make up the stored instances. Without those class definitions all you'll get is placeholder objects (Broken objects) that are of no use at all.
As such, it's probably easier to just get the Plone instance back up and running, as it'll be easier to export the exact data you want out if you have things like the catalog (basically a specialized database index) to build your export.
It could be that this site is down because of something trivial, something we can help you with here on Stack Overflow, or on the Plone users mailinglists or in the #plone IRC channel. If you do get it up and running and have some details on what you are trying to export, we certainly can help.
You'll need to get the system up and running to export data. Data in the data.fs file is stored as Python pickles and is not intelligible to "outside" systems.
As the others have pointed out before, your best course would be to have Plone running back again. After doing so, try csvreplicata to export existing data to csv format. And for user accounts, try atreal.usersinout.

Recently I managed to export Plone 4 site to sqlite using SQLExporter: http://plone.org/products/proteon.sqlexporter. But you need to get your Plone instance working first to use it.
I have a project as follows:
User uploads Excel file to server, server will return back with 2 new columns. User wants us to check prices being charged and we have file that holds average standard pricing.
In the desktop application just done, I use Microsoft.Office.Interop.Excel
for manipulating the Excel file.
But this is not available in Silverlight. Reading is not the issue.
The issue is adding 2 new columns. Program reads excel file using oledb, and oledb is very light and is available in web.
But for creating 2 new columns, I use Microsoft.Office.Interop.Excel that Microsoft provides.
This is not available in web.
I will be need to check how can we do this.
One possibility is to have the program on the server, waiting for a file, process the file, and email back to the user.
I just want to see if there is another way. I don't like this approach it doesn't seem best.
You have a few options for doing this with Silverlight. First, you can use the Excel XML format for the files which means adding a column is just an XML exercise. Second, if that doesn't work, you can upload the file to the server and run the same code you have in your desktop app to update the file. Once it is updated you can prompt the user to save the file back to their hard drive.
If you go the Excel XML route then you would need to create a web service to get the price data from your database out to the Silverlight on the client. Oledb won't work since you don't want to expose your database via oledb on the Internet.
Does anyone have an elegant suggestion for how to get the contents of an Excel spreadsheet into SQL Server via a web form? I need to allow our clients to upload modest amounts of structured data, and I need that data to ultimately reside in a sql table. I really can't expect the clientele to produce anything but an Excel file, but I could require that it be an xlsx.
The web app is written in Coldfusion; it doesn't need to be able to handle huge numbers of simultaneous requests, but I don't want to consider some sort of server-side batch job processing or shunt the user to an asp.net page (which is what we are doing now).
Any recommendations (or examples of how others are successfully doing this) would be appreciated. Due to the sensitivity of the data, we really can't do anything to compromise the security of the web or sql servers.
If you are using CF9, then you could easily use the cfspreadsheet tag too. I mention this one specifically because Shawn's link did not (presumably due to its being relatively new on the CF scene). Here's the livedoc link: http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec17cba-7f87.html
For full use, I would create a web form with a standard file upload field. On the backend handling the form submission, get a copy of the file with
<cffile action="upload" destination="uploaded.xls".....>
Then use:
<cfspreadsheet action="read" query="myExcelData" src="uploaded.xls" ...>
At which point, your spreadsheet content will be available as a query object. You can then loop over this query, running insert queries into your sql server each time you loop. That should do it.
Here are the most notable options to help point you in the right direction; choose what you are most comfortable with (Source: Charlie Arehart).
CFXL
JXLS
CFX_Excel
My personal recommendation is to go the CFX_Excel route. Although a commercial product, it will grant you the most functionality/flexibility of the options listed.
Currently in our research group, we have many "data files" stored on three servers and a couple of personal computers running different operating systems.
We want to build a database, which would store some information in addition to the URLs of those various "data files". My question is, do we have to copy all the data files and put them in a directory in the same server the database is in? Or can they be left as they are on the different computers? If the second case is ok, what would be the format of the url of the "data files"?
It really depends on what your intended goal is and what your current setup is like
If the files are currently sitting somewhere on the network, and you need a path that the application can use to access them, you just need to store the network path (\\server\share\file for Windows environments) in the database, then read it and access that path to access the files. You'll need to make sure everyone has read access to them.
If the files are currently accessible through a website URL, internal or external, then again, you just need to store that URL (or some portion thereof) (http://mywebsite.com/myfile or http://servername/myfile) and access that.
If either of the above are not currently true, but you want them to be, then you'll need to set up a new share/webserver and put the files there. There's no requirement that this be the same server as the database, but it'd make for better backups if it was.
If you want the files themselves to be in the database, you should check out Bob Fanger's link.
Not sure what you're asking here but...
If you want your database engine to read files filled with data, it probably doesn't matter where they are stored - though this may depend on the database you are using. Are you using MySQL? MS-SQL Server? Oracle?
Many database vendors provide relatively easy-to-use admin tools that would let you choose a file to be loaded, and usually the file chooser dialoge lets you browse networks so you could load a file over the network. Details on how to do this vary so consult the manual for your database engine for loading data from a pre-existing file.
Be aware that if the database is on Computer A and the data is being loaded from Computer B over the network, it will probably be slower than if the data was on the same computer as the database.
It doesn't really matter if the files are stored outside the database anyway.
See Storing Images in DB - Yea or Nay? for more thoughts on that one.
If the files accessible by an url, you can store that with the meta data, like
http://server1/folder/file.ext, file://\server1\folder\file.ext or "file://P:\folder\file.ext"
Things to consider:
Backups
Performance
Synchronisation between the meta-data and the data
I want to export all my queries as individual files for purposes of putting them into mercurial source control, but I don't know how to export the individual queries as individual files without having to open each one, then save to the folder, then add into the project, or some equally convoluted process.
I wouldn't mind having to add each one individually, but how do I get them out of the database as individual files without opening them all and doing each one save as? Ostensibly I would like them named with the name they have in the database right now.
I could easily dump the whole lot into one long file using database tasks, but that's not really super helpful is it?
I have SSMS 2k5 and 2k8 (and VS 2k5, 2k8, 2010 to boot) to work with, any thoughts?
Right click on the database. Select Generate Script. On the last page. Script To file you can choose single file or file per object
When you script a database in SSMS you have the option of one file per objects.
SMO is useful with a small app to iterate through
Third party tools like Red Gate SQL Compare (there are other free tools) can script too
I would write a small C# program which extracts your database object via SMO and stores them in your filesystem the way you want.
It is rather easy to write stored procedures which fetches the definition into the result as text. sp_helptext could be used as start.
Than you can use PowerShell to write the Output to the file system.
It sounds as if this would fit rather good into the Really Simple Data Dictionary codeplex project. link text
