Connecting in Oracle DB with VB.NET
Hi, i have to connect in Oracle9i database and i tried every type of samples that this site have but doesn´t work yet.
Now i tried with a OracleClient connection:
Dim StrSql As String
Dim MyConn As OracleConnection = New OracleConnection("User ID=USER;Password=PASS;Data
MyConn.Open()
StrSql = "select * from DATABASE"
But when i Run the application, this is the error:
An unhandled exception of type 'System.EntryPointNotFound
Additional information: Unable to find an entry point named OCIEnvCreate in DLL oci.dll
Could anyone help-me?
Sorry by my English, I´m a Brazilian and I´m learnig the language yet.

1. Right click project ... select properties
2. Click on General from left tree view
3. From output type combo choose console application.
4. change the code something like this.
Public Shared Sub Main()
Dim StrSql As String
Dim MyConn As OracleConnection = New OracleConnection("User ID=USER;Password=PASS;Data
MyConn.Open()
StrSql = "select * from DATABASE"
End Sub

U need a start point in your application. you should declare a public shared function. and make that a strat point.
