عدم المقدرة على اضافة البيانات

لدي مشكلة انني

اضع كود ال Insert

ولكن عند الضغط على Button لا ينفذ ال Insert

والكود التالي

 SqlCeConnection conn = new SqlCeConnection();

conn.ConnectionString = "Data Source=\\Program Files\\DeviceApplication1\\AppDatabase1.sdf;";

// conn.ConnectionString = source;

SqlCeCommand com = conn.CreateCommand();

// com.Connection = conn;



// com.Connection = conn.CreateCommand();

//string sql = "insert into employees (empname) values ('Fadi')";

MessageBox.Show("Hello1");

com.CommandText = "insert into employees (empname) values ('Fadi')";



MessageBox.Show("Hello2");

com.CommandType = CommandType.Text;

MessageBox.Show("Hello3");

conn.Open();

MessageBox.Show("Hello4");

com.ExecuteNonQuery();

MessageBox.Show("Hello5");

com.CommandText = "select count(0) from employees";
