• SQL Server the cost of security auditing

  has anybody investigated the cost of turning on AUDITING for the SQL servers I am talking about enabling the entire C2 Security Audit mode. How much impact the auditing has on the database performance Is auditing for SQL 2005 any better, meaning less impact on performance Any sample, test, and/or numbers to support the arguments Please share any findings that you have or know. Thanks If it is a OLTP (frequent updated) 24/7 based application then it will have impact during the database maintenance jobs and other bulk load jobs, if any. Also you need to take care of disk free space in any case, otherwise the server will have other issues. I suggest you to turn on on the test platform to see what kind of process it follows ...Show All

• .NET Development convert mp3 file to stream and convert again to file

  hi i want to put binary file content to stream and transfer it as i need or leave it alone and then convert back to file how can i do that thanks in advance. This code sample supposes that u have an sqlServer database (test) with a table (mp3Table) that have two columns : ID (nvarchar(50)) and MP3 (binary(8000)). Be sure that the MP3 column length is enough to store the binary file. The maximul length allowed by sql Server is 8000 bits. I think it's not enough to store MP3 files. Anyway. ------------------------------------------ Inserting to the database ------------------------------------------ void InsertMP3(string name, string filePath ) { try { FileStream streamInput = new FileStream( filePath , Fil ...Show All

• .NET Development Where is the SqlContext.GetConnection method ?

  I want to use SqlContext.GetConnection method from System.Data.SqlServer namespace, but there is no SqlServer namespace anymore. I've read that all code was moved to System.Data.SqlClient namespace but GetConnection method vanished. I want to return rows from C# dll library (sql server assembly) to application written in Delphi. I use SQL Server Authentication. Is there any similar method Regards KonRi. Regarding the authentication, please be clear about the concept of context connection. Context connection lets you execute SQL in the same context that your code was invoked in the first place (usually, it's your CLR stored procedure or function). The SPID (SQL Server session identifier) is the same a ...Show All

• Software Development for Windows Vista Sample code needed to understand the UIA

  Hi, I am planning to use the UIA in our environment. Can anybody post a sample code to automate a simple GUI application (notepad) Basically i am looking for how to invoke the notepad application and enumerate the menu items in it using the UIA TIA, ~JK Executing an application programmatically is not part of UIA. Once you have Notepad running, you can certainly use UI Automation to enumerate menu items. There is a great deal of sample code in the SDK that should help you learn the basics of finding UI elements and their properties.

• Visual FoxPro multiple database locations headache

  Hi, I have an application which has a dev and testing environment. Each environment is on the same server, ie \\dataserver\application\dev\data and \\dataserver\application\test\data Unfortunately, I am having major problems with the DEV environment accessing the test (and vice-versa)!!!. Each table is opened with its full path name but the wrong table is opened. This is also true for remote views etc. If I rename the test (whilst running dev or vice versa) area then all is well. I have noticed that the header of the dbfs hold the absolute path to the database and not a relative on. I have even striped all absolute references to tables in the forms out. I am using VFP9 with SP1. Any help would be appreciated Regards ...Show All

• Windows Forms Datagridview unbound computed on bound...which event to use?

  Okay, I've spent the day trying to get this right, and not quite there yet. So much for rapid application development. Please advise My datagridview control has bound columns and unbound columns. I want the unbound columns values set based on a computation against the bound columns. Say my boundcolumn value is a date Sep 20 2006, so I want my unboundcolumn value to be assigned "Wednesday". I can do that fine in various events, but not immediately after the initial databinding...my unboundcolumns are remaining blank until my user starts selecting cells because I haven't solved which event when the datagridview is first loaded to use to calculate the unboundcolumns. Any ideas I've tried after the rowsadded and databindco ...Show All

• Visual C++ How can a C++/CLI library catch unmanaged C++ exceptions from an unmanaged library without breaking the C++ stack unwinding?

  I have a static C++ library, built with VS2005, that is used by multiple projects. The library throws C++ exceptions (derived from std::exception) from its public interface. One project that uses the static C++ library is a .NET class library that is written using C++/CLI. What I have found is that when the .NET class library calls into the unmanaged C++ library and an exception is thrown from within this library, then the application immediately jumps to the .NET class library catch clause without calling unmanaged C++ destructors during stack unwinding. This of course breaks the RAII idiom and is creating a large problem for me. My questions are: Is this expected What is the best solution to work around the problem Many thanks f ...Show All
