Hello there I have been pulling out my hair to try and figure out why my code will not close the MySQL datareader. I need to be able to return the information by using a function

VB

Public Shared Function SQLDATAREAD() As MySqlDataReader
       Dim SQL_CMD As New MySqlCommand
       With SQL_CMD
           .CommandText = "select Names, Boys, Girls from Gender"
           .Connection = MYSQL_DBCONNECTION
           .CommandType = CommandType.Text
       End With
       SQLDATAREAD = SQL_CMD.ExecuteReader
       Return SQLDATAREAD()
       SQLDATAREAD.Close()
   End Function

I have a open connection which works fine but every time the code errors saying that there is a open databasereader which must be closed first but this is the only reader that I am using?

Please help I would like to know where I have went wrong or what I have forgot to add, any help would be greatly appreciated.

Your .Close method is being called after the return statement - so in fact is not being called at all

You have a Return statement before the call to Close.

Use only dataset and mysqladapter ...this is so easy to retrieve a data from mysql database...
example:

VB

Public ds As Dataset
Public da As MysqlAdapter

ds = New Dataset
da = New MysqlAdapter("here should be the sql query to retrieve data", MysqlConnectionString)
da.Fill(ds, "here should be the table name of query")
MsgBox("Success")

You can create you custom function by including my code block to any named function you want just remember > Return value will be "ds" that means Dataset,,,,

Enjoy Programming,,, :)
