DB/Reporting :: Move From An Access MDB File To An SQLExpress(2005) MDF File
Sep 19, 2009
Trying to move from an Access MDB file to an SQLExpress(2005) MDF file and getting lots of problems. I have model my MDF file Like my Access MDB file ,same file name,same number of columns, same columns property,same columns name, see out of the 13 columns 8 have default value, I think I am getting a syntax problem when inserting the data into the table, being new to SQL Express I don't know how to write the proper SQl syntax
See my code for inserting and updating (using Access.mdb) which I whoud like transpose to SQL
'// Insert a record into the database for the node.
sSql = "INSERT INTO [TreeViewItems] (bRoot, dLastModified, iImageIndex," & _
"iParentID, iSelectedImageIndex, iSort, sName, sFullName) VALUES " & _

I'm currently designing a client application that connects to a SQL Server 2005 database. My app is being used to display data, allows users to run reports and stats on the data. It is being developed using VB2008. Within my VB2008 project, the connection string to the DB is made via SQLEXPRESS.
The road block that I'm running into right now is that it only allows me to connect to a local DB file (.mdf) only. I tried to connect to a different DB file on a server within the same network domain, and it generated the following error:
"The file "U:Data.mdf" is on a network path that is not supported for database files. An attempt to attach an auto-named database for file U:Data.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share." (where U: is a mapped network drive).
Below is the actual connection string in my code:
"SERVER=.SQLEXPRESS;AttachDbFilename=U:Data.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
The intention is to have the DB reside on a server, where there is another application that runs as a service to collect the data and then populates this DB. Then my app would just connect to the database, and allows users to run reports based on the data in the DB.
I heard that this is the limitation of SQLEXPRESS: it will not allow connection to a remote database. This is true? If so, is there anyway that I can get around this limitation?
The main reason that I chose SQLEXPRESS in the first place is that because of the licensing issue. The company that I work for do not want to make the users of our software app have to purchase additional license for the full-blown SQL Server Enterprise edition. I also heard that SQL Server Enterprise edition does allow you to connect to a remote DB (.mdf) file.

Im am writing a simple console app that will check and see that a file exists and then if does it will copy the file and move/paste the file into a new location. The file I'm checking exists as a file share on a server and I am wanting to move the file to a folder on a local machines C drive.
I'm working from my machine which is on the domain where the file exists and I'm logged in and have full admin rights on the domain. I can access the file share but when I run my app it gives an error saying access to to the file path is denied. My question is even if I'm on the network do I still need to provide username and password credentials to make this connection? If so how do I do this?

Im looking to set up a VB.Net application that allows me automatically import files from Excel into an Access Database. Can anyone point me in the right direction? I will be importing files regularly so I would like to make an application to simplify the process. Would I be better off creating a Macro that I can reuse in Access or a VBA or?

I am trying to import a text file to an access database in VB2008 express. The text file I am testing with is a csv file with 34,000 records. The problem is this takes 2 minutes to read through all this and write it to the database. The actual text file I will be using in production has over 800,000 records and this will take a ridiculous amount of time. I think I am doing something wrong. I have posted my code below. I am reading a record, parsing out the fields to an array, then creating an SQL statement to insert the record and executing it.
reader = New IO.StreamReader(fname)
Do While reader.Peek() >= 0
linesread = linesread + 1

I'm trying to export a table called material from a sqlexpress 2005 .mdf file called mydatabase to a csv file programatically in vb2008. i was looking at bcp and the shell command to call it, but simply can't get it to work - i'm calling it like so:
Shell("bcp mydatabase..material out 'c: est.txt' -c -T -S .SQLExpress")is there a way to do this without the shell? i would think it would be a little more professional looking for the app as a whole...

is there any way to attach a sql mdf by filename but actually make the database name something else?
the problem i'm having is that my connection string attaches the database just fine, but it gives the database a name of it's full path on the hard drive when i pull it up in SSMSE. ie. "c:program filesmy programmy database.mdf" is shown as the name when i do a sqlcmd and issue a select name from sys.databases
the snag is being hit due to the fact that i'm trying to do a "bcp in" and because a: there are spaces in the database name, and b: there's the .mdf extension also added to the database name that when i run my bcp in command it errors out, even if i use the -q option of bcp.
if i start SSMSE and right click the database and rename it, bcp works great - so my question is, how do i correctly format my connection string to attach to c:program filesmy programmy database.mdf, yet have it attach the database as "mydatabase" for use in bcp statements?
i've been to connectionstrings.com and they only cover the standard connection strings
in summary - i want to attach an mdf file programmatically and specify the name that ssmse see's it as....

I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?

I'm building an aplication with an MS Access database behind the scene. In many of my forms I'm gonna use DataGridViews to show data from the database, not an entire table but data based on manually built queries. So, I have few questions without answers, by now. Solutions or 1. I haven't decided how will I bring the database into the project: from the menu -> Add New Data Source, or within the code, at runtime. I still don't know which one's best or why.2. How exactly can I execute any SQL query (SELECT, INSERT, UPDATE, DELETE etc) on my Access database from my aplication?

Lets just say I had something like this:
System.IO.File.Create("C:.txt")
Dim SaveF As New System.IO.StreamWriter("C:.txt")
Under each other. It gives me a error saying:
The process cannot access the file "C:.txt" because it is being used by another process.

When I load my solution and compile it after first starting the IDE, everything works as expected. After changing source and recompiling, I get the following compile error:
Error 11 Unable to copy file "objDebugCAMDRS.Library.dll" to "binCAMDRS.Library.dll". The process cannot access the file 'binCAMDRS.Library.dll' because it is being used by another process. CAMDRS.Library.
After closing Visual Studio 2005 and reopening the solution I can compile again successfully. This is an old solution that has been fine for a long time. I just recently changed computers and reinstalled everything.I am running win XP Pro sp2, Visual Studio 2005 sp1.

Ideally I'd like to be able to copy/move between an accessible folder on my local drive and a network share that I don't have permission to access (but the application would). I am using impersonation to give me access to the files in the network share but using System.IO File.Move or File.Copy forces me to use the same credentials for each location. Is there a way around this?

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?

I'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.

Public Sub LoadCareer()
Public rs As New ADO

I am asked to write a front end program in VB 2005 (that will run in client computers which running on Win XP) to access an existing MySQL database running in Linux. It is not my preferred choice, but the user have the database and server working just as he wants it, and do not wish to change, at the same time I do not wish to change programming language. Is that even possible? Can we actually write VB 2005 programs that will run in client computers complete with NET framework 2.0 to access a Linux operating database?
