Databases :: Project Using Vb.net With Sql And Sql.Data.dll As A Link To The Database Not Working After Upload?
Feb 13, 2010I have a project using vb.net with mySql and mySql.Data.dll as a link to the database. Now when I test my website from local computer and with live server connection string all works fine. The thing is, when I upload my files to the server, it gives me an error Object reference not set to an instance of an object.I have copied the mySql.data.dll file to the bin folder of my domain and the query that gives the error is a basic insert statement that works from the local machine to the live database.

View 3 RepliesDatabases :: Uploading MySql Database To A Server?
Jan 7, 2010I have few questions regarding MySql database.
First one will be: I've installed MySql, Query broswer, and ODBC connector (not sure what this one does. Can anyone explain?)
Now, when im dragging a new DataGridView into the form, and try to connect it to a MySql database, i can't seem to find MySql in the databases list... why is that?
Second question, assuming everything works fine, how can i upload the database to a server and use it there?
I can think of two problems trying to do this : (1) Im not sure where my Database files are stored at... (for some reason, they are not found in MySql/Data... this folder is completly absent)
(2) While working with ACCESS, all i had to do is to point the .aspx page that did the connecting to the location of the .mdb file, but now, each time i want to reach my database, i need to send the page to the server (localhost). How will i create a connection to my database, when its on another server, in the code page ? (small code example would be nice).
