What is the recommended procedure for applying Sql 2005 "standard" licenses to existing boxes having 2005 enterprise eval. installed I do not want to delete and re-install sql server if at all possible!

• Visual Studio Matrix unwanted rows - additional row group

  I have searched the posts and I think this has not been asked. Here is the setting. Imagine a table with 4 columns: columns 1 and 2 are used to group rows, column 3 is used to group the columns and the 4th column contains the data to display as the matrix data. I am creating the matrix with dynamic rows and columns, with an additional row group. So for every unique col_1 entry there may be several col_2 entries each with its own col_4 data that is grouped keyed off the first column value. The third column is used to display the matrix data broken into months, say. I am subtotaling each row group, as well as all rows and also the columns. ...Show All

• Smart Device Development HELP! Basic Signature Capture on a PDA for a newbie

  Hi, I've been thrust back into the world of development head first and I'm trying to get my head around vb.net 2005 as the last bit of dev I did was in VB6 nearly 3 years ago. I've been asked to put together an app that will allow a user to enter data on a PDA which will then store the information on an SQL database, but, of course, they require a signature field at the end. I've searched MSDN and the web for code and examples but most seem out of date (eVB) or over complicated or costly! The best article I've found was the one posted by Ralph Arvesen on MSDN which came with a working example, however it doesn't just capture the signat ...Show All

• Visual Studio 2008 (Pre-release) Intercepting the Message body

  Hi I'm writing a custom channel + binding that can be inserted wherever in the channel stack. Its mainly used for checking some properties of the message body (in xml format). So far I'm working off the "Custom message interceptor sample", but there seems to be no way to read the body without changing the state of the message/invalidating it. Should I use another approach than a custom channel/binding approach What I like about it is the way you can fit it into a custom binding. So far i've tried/read about these options: 1) In the Request(), Send() etc methods of the custom channel, create 2 copies of the message wi ...Show All

• Visual Studio 2008 (Pre-release) TCP Streaming is Broke in Beta 2

  The release notes document for Beta 2 lists the following known issue with WCF Stream types and operations: 4.1 When Using WCF Steam Types and Operations, May Get QuotaExceededException When Using Binary Encoding When using types that derive from System.IO.Stream as input or output parameters in service operations, QuotaExceededException may be thrown if the binary encoding is being used, even though no quotas have actually been exceeded. This encoding is the default for several standard bindings, such as NetTcpBinding.

• Windows Forms Windows Forms in VB 6.0

  Hi, Is there any success stories in implementing Windows Forms inside VB6.0 MDI Form Is there anyway to fake the appearence atleast. Thanks, Raghu Raghavendra RAV wrote: Hi Siva, I am able to get my .NET Winform in VB6. But the thing is I am not able to make it as a MDI child of a VB6 MDI form. This is where I am stuck up. Thanks, Raghu Haven't used Vb since Vb4, so what I am saying may not be totally accurate. But I don't think you can directly make a Form an MDI child. You'd have to create it inside a normal MDI child VB form as a child control that resizes to fit its parent (the VB6 mdi child). ...Show All

• SQL Server Native Client connection to MSSQL 2000

  For MARS support in SQL Server 2005, I'm changing our OLE DB code to use Native Client. My understanding is that Native Client should support SQL Server 2000 as well. When I point my DBPROP_INIT_DATASOURCE to a 2005 instance, everything works great. But when I point to a 2000 instance, the IDBInitialize->Initialize() call is crashing with a bounds violation. In my test case, the only change I made was in my coCreateInstance from this: ::CoCreateInstance(DBIO_CLSID_SQLOLEDB, NULL, CLSCTX_INPROC_SERVER, IID_IDBInitialize, ( void **)&m_handles.pIDBInitialize); to this: ::CoCreateInstance(CLSID_SQLNCLI, NULL, CLSCTX_I ...Show All
