I am trying to do a TableAdapter.Fill(dataTable) and it fails with the above error. Here is the code in …DataSet.Designer.cs

[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.ComponentModel.DataObjectMethodAttribute(global::System.ComponentModel.DataObjectMethodType.Fill, true)]
public virtual int Fill(ZenwareDataSet.BatchPDADataTable dataTable) {

     this.Adapter.SelectCommand = this.CommandCollection[0];
     if ((this.ClearBeforeFill == true)) {
         dataTable.Clear();
     }
     int returnValue = this.Adapter.Fill(dataTable); //  <---Fails here.
     return returnValue;
}

This is generated code. Maybe there is something that I need to change? I am wondering if my app has multiple connections to the database. What can this be? Thanks for any help you can provide.

    It seems the answer to this question is to make sure nothing keeps a connection open. Since I had inherited this problem, I was not aware of everything that could hold an open connection. Once I centralized the connection in a single function I have not seen the error.
