When you create the parameters there is a property called Direction and set it to Output

After executing evaluate that parameter value.

You can do something like this:

'Sql Command
mSqlCommand = New SqlCommand
mSqlCommand.Connection = YourConnection
mSqlCommand.CommandTimeout = iTimeout
mSqlCommand.CommandText = yourSP
mSqlCommand.CommandType = CommandType.StoredProcedure

Dim param As SqlParameter() = { _
            New SqlParameter("@ParameterInput", SqlDbType.VarChar, 2), _
            New SqlParameter("@ParameterOutput1", SqlDbType.VarChar, 4), _
            New SqlParameter("@ParameterOutput2", SqlDbType.VarChar)
        }

param(0).Value = yourInputValue
param(1).Direction = ParameterDirection.Output
param(2).Direction = ParameterDirection.Output

'Add Parameters
For Each param In paramArr
   mSqlCommand.Parameters.Add(param)
 Next

'Exec NonQuery
 mSqlCommand.ExecuteNonQuery()
OutputValue1 = Convert.ToString(mSqlCommand.Parameters"("@ParameterOutput1).Value)
OutputValue2 = Convert.ToString(mSqlCommand.Parameters"("@ParameterOutput2).Value)

Open in new window

There was an error in the loop to add parameters
'Sql Command
mSqlCommand = New SqlCommand
mSqlCommand.Connection = YourConnection
mSqlCommand.CommandTimeout = iTimeout
mSqlCommand.CommandText = yourSP
mSqlCommand.CommandType = CommandType.StoredProcedure

Dim paramArr As SqlParameter() = { _
            New SqlParameter("@ParameterInput", SqlDbType.VarChar, 2), _
            New SqlParameter("@ParameterOutput1", SqlDbType.VarChar, 4), _
            New SqlParameter("@ParameterOutput2", SqlDbType.VarChar)
        }

param(0).Value = yourInputValue
param(1).Direction = ParameterDirection.Output
param(2).Direction = ParameterDirection.Output

'Add Parameters
For Each param As SqlParameter In paramArr
   mSqlCommand.Parameters.Add(param)
 Next

'Exec NonQuery
 mSqlCommand.ExecuteNonQuery()
OutputValue1 = Convert.ToString(mSqlCommand.Parameters"("@ParameterOutput1).Value)
OutputValue2 = Convert.ToString(mSqlCommand.Parameters"("@ParameterOutput2).Value)

Open in new window

following is just sample for you...

SqlCommand cmd = new SqlCommand("CustOrderOne", cn);
cmd.CommandType=CommandType.StoredProcedure ;
SqlParameter parm=new SqlParameter("@CustomerID",SqlDbType.NChar) ;
parm.Value="ALFKI";
parm.Direction =ParameterDirection.Input ;
cmd.Parameters.Add(parm);
SqlParameter parm2=new SqlParameter("@ProductName",SqlDbType.VarChar);
parm2.Size=50;
parm2.Direction=ParameterDirection.Output;
cmd.Parameters.Add(parm2);
SqlParameter parm3=new SqlParameter("@Quantity",SqlDbType.Int);
parm3.Direction=ParameterDirection.Output;
cmd.Parameters.Add(parm3);
cn.Open();
cmd.ExecuteNonQuery();
cn.Close();

Correcting another error:
OutputValue1 = Convert.ToString(mSqlCommand.Parameters("@ParameterOutput1").Value)
OutputValue2 = Convert.ToString(mSqlCommand.Parameters("@ParameterOutput2").Value)

Provide it two parameters but ignore the return value of one parameter.
