View 1 RepliesI have written a new app in VB.net as a front end to a mySQL database held on a PC on the LAN running Windows XP. This worked fine for a while. The PC running the mySQL server started locking up (XP errors, not mySQL errors according to the event logs), so I decided to have a go installing Ubuntu to run the mySQL server to see if that was more stable.Ubuntu 11.10 is now installed, and mysql server is also running. I have imported the old sql database files and the mySQL workbench shows all tables are imported successfully.
HOWEVER, I cannot get my VB application to connect to the database now it resides on Ubuntu - just returns "Unable to connect to any of the specified MySQL hosts" when i try to open a connection. I am fairly new to Ubuntu and MySQL, and don't know if the fault lies with the O/S (a firewall config problem perhaps?) or if I need to do something different with mySQL.I can ping the Ubuntu pc from the client pc and vice versa.I have used ufw to open port 3306 on the server The ufw logs do not show any errors when I try to connect from the client pc, so I don't think it's a firewall problem (but could be wrong). I thought it may be something to do with the usernames I use in the connection string, but when I change these (deliberately use the wrong password for example) I get the same message, rather than a username/password error Is anyone else using a client PC running Windows (W7 or XP) to connect to a mySQL database running on a Ubuntu server?
I added a new database using SQL Server Management studio express 2008. I can connect to that database using Web Developer and Visual Studio just fine. But when I try to connect from VB Express 2008 I get an error message "file in use by another program". VB only prompts me for the name of the database, but Web Developer and Visual Studio prompts me for both server instance and database name. I'm sure this is just something simple I'm missing.
View 2 RepliesRunning off my laptop: Visual Basic 2010 Express & SQL Server 2008 . I've successfully been able to use the connection wizard to connect to my database in vb.net and read/write data using datasets/tableadapters/binding_source etc.
Now I am trying to create an SQL connection via code to connect to my database to do some more complicated queries. I was successful in being able to connect to my database with SQL, but by doing so it produces an error when it tries to run any .Fill() methods from my TableAdapters below. The error produced is the following: "SqlException was unhandled. Cannot open user default database. Login failed. Login failed for user 'Chris-PCChris'".
If I remove my SQL connection code, the TableAdapter.Fill() methods will work fine.

how to connect database in vb.net using msaccess
View 1 RepliesI'd like to make a little vb.net program that executes searches on a msaccess database. I use a textbox to get the value to search and than i'd like to search all the values that has the textbox value in the middle. So, the queries should look like this: SELECT Rec1, Rec2, Rec3 FROM Table1 WHERE Rec1 LIKE "*" & txtTextBox.Text & "*"...My problem is that i don't know how to pass the "*" character to my query, if I build a string that i pass to OleDbCommand(), the query returns nothing.

I've created a VB.NET Windows Form application which pulls info from an MSAccess database via datasets and tableadapter. When the user makes a change to the data, I use the Update method of the tableadapter to send the changes back to the database. This all works fine in the Visual Studio 2008 IDE, but once the build is done and the application is installed, I run into problems. The application keeps the original data and will not read or write to the database, although any changes I make through the application are mysteriously saved somewhere. If I make changes directly to the database using MS Access - which I need to be able to do - those changes don't show up in the data pulled into the application.
