Sql Server - Using C# (SSIS) To Write Image To Disk
Nov 29, 2011I'm currently creating an SSIS job that will pull picture data from a SQL database and write each picture to a file. We have an ID system that stores all images taken of staff directly to database fields, but we're going to be moving to a new system that stores all of the images as files in paths by User ID.
I have already created my main data flow that gets all of the users and the proper path, but I'm having trouble writing the script component that will create the images. I have the image data as a string, but how do I get it to go out to a file at the proper path?

Write Server Applications In ASP.NET And Visual Basic?
Mar 4, 2010I am looking into writing a web-based vehicle tracking system. The framework I have in mind looks something like this:
Client application --- Database --- Database updater.
Client application: This would query the database for information and then display this information on a map.
Database: holds vehicle information such as speed, location, payload etc.
Database update: This application would need to continually check for information received from vehicles and then add that to the database.
I am confident that with my current skill set and some research and learning, I could write the client application and interface it to a database. However, I am at a loss as to how to write the database updater. Presumably, this would be an application running continually on the server, waiting for information to be received from vehicles and updating the database. Is this something I can do with ASP.NET and Visual Basic? Or would this require a different way of thinking than writing web pages?

View 3 RepliesData Transfer From Ms Access Or Sql Server To Sql Server
Jul 6, 2010I want to know how you can export data from a disconnected database that could be access or ms sql to an sql server database.
Here is the scenario:
I have several software in a remote sites on either sql or ms access databases as back-ends...and I have another sql server database that i want to consolidate data from the remote sites.
One solution I have been thinking about is to use email to send incremental backups of the databases to the main database using a separate piece of software and have another one on the main server to pull that data into the database.
Basically am looking at setting up the remote databases as linked servers at the main database and then having incremental backups sent by email to the main database.
I have thought of replication but the internet link at the sites is terrible.
Is that a good implementation? If yes
How do i get to send the incremental backups and get them imported?(the code)
Tools:
Visual basic 2008 standard edition..Net 3.5
SQL Server 2005.
32 bit architecture.
SMTP Mail Server Coding - Write A Port Listener And Display The Message In A Text Box?
Jan 31, 2012I am looking to make a SMTP (Port 25) listener to listen in and accept incoming mail, look at the message source, make changes if needed, and retransmit the message out another port.

View 3 RepliesImport Excel Data Into SQL Server - ERROR: "ODBC --Connection To {SQL Server} Servernamesqlservername Failed"
Aug 13, 2010I am trying to do something fairly simple.. allow my user to import thier data from Excel into SQL Server, where it can be used by the application.To do this, I'm using the fairly simple code that is common everywhere I look:
strFilePath = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fdlgFileOpen.FileName + ";Extended Properties=Excel 8.0"
connExcel = New OleDbConnection(strFilePath)
connExcel.Open()
[Code]...
Now, on my development computer this code works perfectly. The data imports, and I can go on my merry way.
On the TEST computer, this code throws the error: "ODBC -- Connection to {SQL Server} servernamesqlservername failed." This seems very odd to me, because I'm using exactly the same SQL Server and database to interact with the application, and all the other screens in the application work perfectly. The test computer CAN connect to this SQL Server, but it keeps throwing this error whenever I try import data from Excel.I've tried everything I can think of - using the server's IP address instead of the server name, sending the SQL Server administrator data along with the request, taking out the Trusted_Connection=Yes... nothing works. What is going on here? How can this code work fine on my computer, and hiccup on another?

Read/write Some Data ?
Feb 13, 2012My first question has to do with the opening lines needed in a VB program in order to connect to Excel 2007 and read/write some data from/to it. I know the process only slightly and reading and writing to the cells is not my real concern for the moment. What I need to become familliar with are the lines like this:
CODE:
This is just one of the examples I have read through and to be honest I only follow this slightly. The trouble was that with each new article I read, people did this differently, not the variables on the left mind you, just that some left out lines, which I can see could be done based on circumstances. Still others said the Imports line was not needed....etc...and other loaded up at least 3 or four more Imports lines insisting all were needed.
I'm looking for some straight-forward advice on what is the minimum needed to access an existing Excel spreadhseet and to just read some of it's cells to variables in the code and then writed some data back to certain cells within the spreadsheet and then save and close it.
Also, please note that I am using VB 2010 Express. Why, because I'm a broke developer who spent most of last year out of work. I have a new contract assignment which is so far going well but will go even better if I can master this technique with VB.NET, not VBA. And all the docs I've read said that even though VB 2010 Express is a watered down version of VS, I should be able to do medium level tasks such as this with it.
