• SQL Server Service account not being used to access remote resources

  I understand that the security model for access to external resources changed in SQL 2005. However I thought that if connecting via a SQL account then the SQL 2000 behaviour was used I however have the following situation. Running a BULK INSERT from a remote machine with a SQL user account fails with error Cannot bulk load because the file "...." could not be opened. Operating system error code 5(error not found). However running the same using a instance of SSMS on the server, connecting using the same SQL login, works. I know this is an impersonation/delegation issue however I don't know what needs to be impersonated. To add to the woes this is an NT4 domain. This is not in an windows 2000 domain.

• SQL Server sql 2005 to sql 2000 linked servers problem.

  We have two sql servers using Windows authentication. One is sql 2000 the other sql 2005. When logged in as "sa", I can link these servers and run a SELECT distributed query without any problem. But when one of our developers runs the same query (he is "dbo" of each database on each of the servers) he gets the error: "OLE DB Provider "SQLNCLI" for linked server <Servername> returned message "Communication Link Failure" ... Login failed for user '(null'). reason: Not associated with a trusted SQL Server connection" Despite that, I, as "sa" equivalent, have no problem so it appears to be a permisisons issue.

• Windows Forms Hoping for a clean uniform grey background on winforms application startup...

  two questions I guess. 1. On the startup of my application which has various windows forms controls and user controls, a few of the controls are visible (or at least their outline can be seen against the otherwise control grey background) and a couple of the controls are completely transparent to whatever happens to be underneath them. How can I code the form_load event or other relevant events to have all the controls emerge at once. are SuspendLayout/resumelayout don't seem to be doing the trick, if I understand their purpose correctly. I guess I don't. 2.. How can I iterate through all the controls on my form to at least test out different ideas. The docoument outline view shows all the controls that I would like to be able to app ...Show All

• Visual C++ C++ code compiled with Visual C++ 2005 Express runs slower from the IDE

  I have noticed that my code runs slower when invoked from within the IDE. The debug code runs a small job in 21 seconds from the IDE (no breakpoints set) and in 6 seconds when invoked from Windows explorer directly. The release code runs in 11 seconds from the IDE and 1 second when run directly. For comparison, I tried the same code generated by Visual C++ 6 and got 14 seconds when running from the IDE and directly. Is there some setting that affects this I could not find any. Is this normal behavior for this version of Visual C++ Thanks, Peter Bite Qiu, Thank you for your response. It was very helpful. I would just like to clarify a couple of things before putting this to rest. ...Show All

Have a look on google. 2) You will need to link to other libraries that can write in pdf. Html would have to be coded by you, just export the data into a <table></table>.
