In W2K3, you can create a new application pool for the report server service and then assign it to the report server virtual directory. You can do this in the Reporting Services configuration tool. When you use this tool, the application pool will be setup they way you need it for ...Show All

• SQL Server Package cancelled

  Hi, I'm trying to transfer data from a DB2 database to a MS SQL Server database (approx. 150 000 rows). When I execute the package, the process is always cancelled (In output window: SSIS package "DB2_test_TranAddl.dtsx" finished: Canceled.) I use a view on DB2 to provide the data and I can modify it to return only a few rows.  To achieve this, I use a WHERE clause: WHERE OUTLET_NO Between X And Y. When I try OUTLET_NO Between 1 And 5 (255 rows) the package executes successfully. When I try OUTLET_NO Between 5 And 10 (388 rows) it works. When I try OUTLET_NO Between 1 And 10 (643 rows) it fails!! Any idea   Fleo, ...Show All

• Visual C++ Unmanaged C++ and VS2005: Hidden .NET Requirements?

  Hi everyone. While developing some unmanaged C++ DLL that uses COM and ATL, I've been having issues with deploying the DLL to other machines - those without .NET Framework v2. I've found out after some digging that changing the runtime library from its default to one of the debug libraries (and none of the DLL ones) removed this dependency, but introduced some crashes that im not entirely sure are related to my own application's logic. What is the proper way of creating unmanaged c++ DLLs in VC++2005, Who use ATL and COM Thanks in advance. You make many valid points. I tend to agree, however, I'm trying to live by the other approach (dynamic) for a while to see how it works out. Who knows, I may switch ...Show All

• Visual C# What are Generics? what do I get from them?

  If anybody can provide a sample code, much better. Thanks, Omar thank you ahmedilays, What I am trying to understand is the 'scope' and 'definition' of this 'Person' class type. When you specify, for example the integer type, you can only have elements that are of the integer type. If you try to add a string element to the collection, you get a compiler error and this is what i mean by definition and scope. How is the scope and definition of a class or object type determined in generics And when you add a Person or Car class or object type to the list what would the code look like Let me know if my question don't make sense.
