I am developing a windows application which using VS 2010, in this application I am using firebird 2.5 database and c#.net language.
when i am debugging my application I am getting an error message, showing "Cannot evaluate expression because a native frame is on top of the call stack" I am getting this message at the step 3.
1. if (IsAlreadyRunning())
4. return false;
in my singleinstanceApplication class and also at the while statement for reading the data from the DataReader object.
cmd.CommandText = "select acct_name from iaccounts where comp_id=" + GlobleData.Companyid +" Order By (acct_name) asc";
reader = cmd.ExecuteReader();
if (reader.HasRows == true)
What are the reason for this type of errors? Can any one solve my doubts Please.
