QuestionAsync await error Pin
Carlos581-May-20 11:01
MemberCarlos581-May-20 11:01 
Hi all!
I've got a Windows Forms (C#) project with a combobox that is populated when the form loads
The problem is that the loading of the combobox is slow, and since the loading is done when the form is trying to display the entire form isn't shown until the combobox have been populated. This can in some circumstances be 20+ seconds.

I've tried the code below, using async and await , but it not works....return error :

"This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread."
Any help will be appreciated....

Thank you...

private async void Form1_Load(object sender, EventArgs e)
       {
           await Task.Run(() =>
           {
               LoadMyCombo();
           });

       }

private async void LoadMyCombo()
       {

           OleDbConnection con = new OleDbConnection(conex);
           string strSQL = "select  * from Customers order by cust_name";
           try
           {

               con.Open();
               OleDbDataAdapter adapter = new OleDbDataAdapter(new OleDbCommand(strSQL, con));
               DataSet ds = new DataSet();
               adapter.Fill(ds);

               mycombo.DataSource = ds.Tables[0];
              mycombo.ValueMember = "code";
               mycombo.DisplayMember = "cust_name";

           }
           catch (System.Exception erro)
           {
               MessageBox.Show("Error.... " + erro.Message);
           }
