Make ODBC Data Source Available On Network Interface?
Mar 4, 2009
I used the ODBC Data Sources admin panel to create a "data source" for an ".mdb" file. This was very easy. I can access the mdb (database) file via an ODBC driver, locally. However I need to access this data source over the network. Can anyone please help me learn how to make this same database available on the host's network interface? Perhaps there is a tutorial, video, or some other documentation that explains how to modify a data source to make it available on the network. I am using Windows XP. I hope this does not require a special Windows server distribution.

I have an old VB6 program which copies data from a legacy system (Btrieve 6) into our SQL Server so it can be served up on the web and used to feed some of our other needs. The legacy system outputs a file and a feed program posts it into the legacy ODBC database. The program isn't anywhere near realtime and I am now finding the delay between data going into the legacy database and then into the SQL database is becoming unacceptable so I thought I'd look at VB.NET and see if I could find a better way of doing it using FileSystemWatcher so that when the legacy output file is renamed I can then start a copy of the record affected from the legacy to the new database.

I need to connect to an MySQL database in my VB.NET application (VB 2010 Express). When I attempt to use the Data Sources wizard to establish the connection, it does not provide an ODBC data source. I'm using Add New Data Source/Database/DataSet/New Connection which shows the Add Connection dialog. The only options it gives me for data sources are Access & SQL Server and the OLEDB data provider. It does not appear to give me the option of adding a new data source provider. Attached is an image of my current Change Data Source dialog. Where do I get the ODBC data source provider and how do I install it into Visual Studio?

I'm using Visual Basic/Studio 2010 Express to run my VB program using MS Access database. I'm going to convert the Access database to a SQL Server Server Express data base so I downloaded SQL Server 2008 R2 Express onto my pc with Windows 7. The installation went fine and I actually converted my Access database to SQL server. I did not change anything in my VB program.My problem: When I run my normal program with the Access database (no changes), I now get an error when it executes the following code:
dr = cmd.ExecuteReader.
I get the error System.Data.OleDb.OleDbException was unhandled;
ErrorCode=-2147467259; Message=ODBC--connection to 'SQL ServerBilotta-pcsqlexpress' failed.

It appears the ODBC is looking for the SQL server eventhough the program is pointing to the MS Access db. How do I get it to NOT look for the SQL db? Is there a default setting for the

I have this snippet in Java:
final InetAddress address = InetAddress.getLocalHost();
final NetworkInterface ni = NetworkInterface.getByInetAddress(address);
key = new String(ni.getHardwareAddress());
"key", on my PC returns:

What would be the equivalent to get the same output in VB.Net? I have tried getting 'MAC Address' and 'Physical Address' but they do not compare to the output in Java at all?

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

I have a small vb.net application that fires a crystal report through crystal viewer.
The report uses an ODBC connection provided by 32-bit software accounts package, which is installed in the ODBC 32-bit This all works fine on 32-bit XP and 32-bit Win7 with no problems, When run on a win7 64-bit machine the application launches ok, but when it comes to running the report, it prompts for a database logon box for the odbc connection.
When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,

I've been having huge problems having a VB.NET Windows Forms program run as a scheduled task under XP SP3. The program runs when I set the task up to use my non-admin network username and password, I can see the interface fine (albeit without the desired results - the program requires access to remote shares). When I set the task up with the network administrator account credentials, the task is "Running" but I do not see any interface. It doesn't error - it just kind of sits there happily in the background.

I am trying to do is to draw a ray of light emitted by a light source and it is going to be reflected mirrors. I rotate the emitter and mirrors and the ray of light shold obey the laws of reflection. The emitter and mirrors are in an opaque room which means light should not go out. Where I am now is that I am able to draw the ray but when the angle is 90 degrees ( +or-) all the drawing disappears. I set some conditions to make up for this situation, but it does not seem to work. Besides if the angle exceeds 90 degrees, the line is drawn in the opposite direction.One other thing that happens is I set the ray to stop when either end_x_emitter_ray or end_y_emitter_ray = 500. It works for the end_x_emitter_ray but not for the end_y_emitter_ray[end_x_emitter_ray and end_y_emitter_ray are the point where the ray end]I have uploaded the my whole code here. Can you guys suggest me what can be done to make it work appropriately?

I've downloaded the ODBC driver and the MySQL driver and installed them on my system (Win XP SP3). However, the only data sources that are showing up when I try to add a data connection are Access & 2 SQL Server objects. Is there something else that needs to be setup in order for Visual Studio to allow additional data sources? I'm currently running VS 2010 Express.

I think, although I am not sure, that my problem may stem from the fact that I am trying to do something with a DB2 Packed Decimal Field.If I use MS SQL to import data from an iSeries file I can do something like this Select a, b, c, sum(d) from a file where (criteria here) group by a, b, c Note: field d is a packed decimal field.
In VB using an ODBC connection I can do this: select a, b, c, d from a file where (criteria here)but when I try to do this Select a, b, c, sum(d) from a file where (criteria here) group by a, b, c I am getting an error: -2147467259 (80004005).
I want to do this using VB in Excel because I want the user to be able to input data on the spreadsheet that defines some of the selection criteria.

I'm using the Microsoft Excel Driver to import an Excel document into a adodb.recordset so that I can remove duplicate rows and put it into the SQL Server database.
The first column has values like 192, 13U, JJJ, etc. but for some reason the query casts it as a double value, and any rows with alpha values get converted to Null. From what I can tell this is because the Majority type is numeric instead of text.
I tried casting it, but got an error.
Here's my function:

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

I have Informix Dynamic Server 11.50 and Informix Client SDK 3.5 installed on my server. I am developing a .NET application to read data from Informix database using ODBC functions. In the database, i have a table with columns of Serial and BigInt data types defined. My data retrieve function looks like this [Code]
I've tried to modify the columns with Serial and BigInt data types to Integer. And, everything works fine without modifying a single line of code. I do need some advice how to overcome this problem as i need the Serial data type column as an incrementing id column. For BigInt data type column, may be we can change it to column with Integer data type instead.
