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

After executing evaluate that parameter value.

can you show the code both in asp.net and store procedure for simplification?

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)

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)

following is just sample for you...
what error come at your code.

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.
