Hi,
I am having vb2003-net 1.1

Code was working fine yesterday, today getting error
-----------------------------------------------------------
error:
An unhandled exception of type 'System.Data.SqlClient.SqlException'
occurred in system.data.dll
Additional information: System error.
-----------------------------------------------------------
Last line is highlighted. error while calling method for second data
adapter
-----------------------------------------------------------
My Code is :
Dim mDataSet As New DataSet()

Dim mConn As New SqlConnection()
mConn.ConnectionString = "Data Source=localhost;initial
catalog=transport;integrated security=XXX"
mConn.Open()

Dim mStr1 As String = "select * from mItem"
Dim mStr2 As String = "select * from mPump"

Dim mAdapter1 As New SqlDataAdapter(mStr1, mConn)
mAdapter1.Fill(mDataSet, "mItem")

Dim mAdapter2 As New SqlDataAdapter(mStr2, mConn)
mAdapter2.Fill(mDataSet, "mPump")
--------------------------------------------------------------

Need help...

Thanks,
Regards,

Rachana,

Probably if you remove the
mConn.Open
it will work.

The dataadapter does its own opening of the connection as long as that is
not opened already.
