• SQL Server Report performance issue - time in processing

  I'm having performance issues with a report which is taking nearly 22 minutes to return 2100 rows. I've queried the execution log tables and the Time in Processing accounts for more than 99% of this. The report is applying cell formatting using a coded function to retrieve formatting from a stylesheet which hasn't proved problematic so far with other reports, and has several levels of grouping in a single table with sub-totals for each group level and an overall table total. There's also conditional criteria for the grouping expressions depending on report parameters passed in. Anyone have any ideas as to the most likely cause for the ...Show All

• Architecture Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project. Then maybe I will write mapper classes for bussiness classes to map DB tables or using an O/RM tool or an ODBMS . Think that this project is big one and it has long deadline. You will develop it 2 or 3 years. Requirements will be changed. To develop this project with OOP designs and n-Tier application design is good idea. But I am asking myself this question "Why am I choosing this long way ". I think the advantages of OOP are re-usable and flexible (when there is a new requirement). OOP makes less code behind user-interface. But I dont un ...Show All

• Windows Forms Determining Drive type at runtime

  I have an application which uses the openfiledialog control to allow users choose a destination drive for writing purposes. I need to be able to determin at runtime, if the returned directory from the openfiledialog is a local or network drive... please help Chinedu wrote: I have an application which uses the openfiledialog control to allow users choose a destination drive for writing purposes.

• SQL Server Stored Proc/Table Truncation

  In SQL Server 2000 I know there wasn't a way to force SQL Server to throw an exception if the data being input in a table is greater than the allowable field size and instead it will simply truncate the data and insert the truncated data for that field. I'm curious if SQL Server 2005 has an option like Oracle and DB2 to force an exception to be thrown if truncation would need to occur to input that data. I know this can be validation in the client-app, I'm looking for a solution w/ regard to SQL Server throwing this exception. Thanks! SET ANSI_WARNINGS will work for most cases. But that will still not catch cases like passing values to ...Show All

• Visual C# Thread Safe Access to DateTime

  Hello all ... I'm working on a class to return the current date. It is a bit more complex than the following code due to managing cultures, but below is the basic idea. My question is: how can I ensure the execution of the get property is thread-safe, without single-threading my application My understanding from the doc that is that I need to be thread safe when using DateTime. I was thinking that lock would be too restrictive and with a lot of calls to this class would almost single-thread my application. Would a Read Write Lock be appropriate here Some other approach Thanks so much for your suggestions! Doug ...Show All

• Smart Device Development MDE: Can't run Device Emulator Manager

  I'm trying to run the Device Emulator Manager on my Win2K desktop. It terminates immediately without a message, whether I start it from the Start Menu, from Windows Explorer or from the cmd line. The emulator itself starts up and runs fine. I'd like to set up an ActiveSync connection to this. As I understand it, I need to get the Device Emulator Manager running to do this. Hi George, That means that the breakpoint was not hit for some reason - most likely because it did not bind to the right place. I made a test file you can run so we'll see the registration error - I've sent it to the email address fo ...Show All

• SQL Server FMTONLY, LONG Running ?

  Hi There I have been running a trace for long running queries. I know what FMTONLY is, simply returns the metadata of the query. I have found something odd.
