• SQL Server How to use ODBC SQLSetConnectAttr from C# ?

  Hi, I'm having problems dealing with some large datatypes in a C# application using odbc. Basically certain datatypes, such as db2 CLOB, are not recognized as 'valid' by the odbc driver. It seems the fix is to use the SQLSetConnectAttr function using the appropriate key/value pair to 'map' those to datatypes known to ODBC but I'm not sure how to use it in C# code. The template seems to be more an unmanaged C type API with handles being ...Show All

• Windows Forms When to dispose TableAdapter?

  Do I need to think about it Even I could ask: do i have to think about constructing it in every form again Thanks Peter TableAdapter's a Web component, right   I don't see that it's disposable.  Maybe you meant DataAdapter In any event, the general rule for Dispose is to dispose when you're done with the object, if it has a Dispose method.  Some objects help you a little with this.  For in ...Show All

• SQL Server New to SSIS and have a simple question

• Visual C# How to dynamically check if a type supports the "+" operator
