Hi every body,

I have that code:

When i run my web project there are three different messages appear,
every message appear in one time.

When i make run, message error appear for that code:

C#

public static int GetNumOfTopicInTable(out int TopicsNum)
    {
        topicCommand.Connection = connection;

        topicCommand.CommandType = CommandType.StoredProcedure;
        topicCommand.CommandText = "uspNumOfTopicInTable";

        connection.Open();
        TopicsNum = Convert.ToInt32(topicCommand.ExecuteScalar());
        connection.Close();

        return TopicsNum;
    }

when the caller reach to that line of:

MIDL

connection.Open();

this error appear:
The connection was not closed. The connection's current state is open.
Although it is first time i open it.

But when i close VS 2005 and open it again and make run this message appear:
There is no row at position 9.

for that code:

lbtnHomeTopicAddress.Text = topicDataSet.Tables[0].Rows[i]["TopicAddress"].ToString();

And when i try to run project by press on F11 this another message appear:
Procedure uspNumOfTopicInTable has no parameters and arguments were supplied.

for that code:

TopicsNum = Convert.ToInt32(topicCommand.ExecuteScalar());

any one can help me please

Solution 3

I found the solution for my problems and it is that:

first problem:

The connection was not closed. The connection's current state is open.

solution:

I used try....catch...finally:

C#

try
{
   connection.Open();
   TopicsNum = Convert.ToInt32(topicCommand.ExecuteScalar());
   connection.Close();
}
catch
{

}
finally
{
   connection.close();
}

second problem:

Procedure uspNumOfTopicInTable has no parameters and arguments were supplied.

solution:

I used this code:

MIDL

topicCommand.Parameters.clear();

the last problem is custom problem that related to my code and i solved it according to my case.

Thanks every body
bye
