Pseudo code something like this: UPDATE Table1 SET item1, item2, item3, item4 WHERE Table1 is TOP 1 ORDERED BY column2 ASC column1="email_address" So i want to update only the most recent entry of a customer with a specific email address.

• SQL Server transaction log size growing very large

  hi all, my tlogs at the subscriber are growing very large irregardless of my recovery mode. any help using snapshot-push replication thanks, joey If you want data to be bulk-loaded in small batches while the snapshot is being applied to the subscriber, you can: 1) Specify the unofficial /DisableResumableSnapshot parameter on the distribution agent command line, this will prevent each bcp file from being applied in an atomic transaction 2) Specify a smaller batch size via the /BcpBatchSize parameter Alternately, you can try to get the benefit of minimal logging by taking advantage of partition switching support as follows: 1) Deliver snapshot to an empty staging table 2) Switch the staging tabl ...Show All

• SQL Server Microsoft.SQLServer.ManagedDTS.dll reference error in VB.Net 2002

  I am using VB.NET 2002 and we have set up a test environment running SQL Server 2005. I am trying to add a reference to Microsoft.SQLServer.ManagedDTS.dll which is required to run a DTS/SSIS package from VB.NET. However the dll does not show in my add reference listing so when I select BROWSE and select the actual DLL I get a rather long error message telling me that only 'dll' and COM components can be referenced. The exact message is: A reference to 'C:\Programs Files\Microsoft SQL Server\90\SDK\Assemblies\Microsoft.SQLServer.ManagedDTS.dll' could not be added. This is not a valid assembly or COM component. Only assemblies with extension 'dll' and COM components can be referenced. Please make sure that the file is accessible, ...Show All

• Visual C++ C++/CLI managed code calling methods on unmanaged C++ classes call incorrect functions

  Hi, We are doing a transition project where we are wrapping unmanaged C++ code with C++/CLI managed classes. The various methods and properties on a given managed wrapper class are mostly just pass-through calls to the wrapped C++ class. Mostly this works fine. Sometimes, however, the call from the managed code ends up in the wrong C++ function. IOW: void ManagedMethod1( void ) { m_pUnmanagedObject->Func1(); } actually calls pUnmanagedObject->Func20(). So far, it seems that every time this happens, the called method on the UNmanaged C++ class is declared "virtual"; it also seems that the incorrect method that is actually called is also declared virtual. I have tried in one or two situations to change the leg ...Show All

• Windows Forms Event name when form is brought back into focus

  Form has been minimised, i then use alt +tab to bring it back into focus. What event name is this. There doesnt appear to be an event name focus. sorry if this is really obvious, is early :) Does anything happen before this event I listen to this event, have a breakpoint as soon as it is called, yet the breakpoint is never reached, an exception happens. whenever the application loses focus then gains it again, this occurs. It says : Cannot access a disposed object named GroupBox. But from what i can tell, the UI on the form doesnt contain a groupbox and shouldnt contain one. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. GDI+ question

  If this is the wrong forum for a GDI+ question, please move it where it should be, thanks! I am leaning to use GDI+ in a simple C++/CLI windows application, and I can draw lines and boxes to my hearts content in a window, but as soon as I move the window off the sceen/minimize it, etc, the picture that I have drawn disappears. I have a feeling there is a simple reason for this involving binding the image appropriately to the window, but I can't figure it out. All I do is make a button that runs the code below when it is clicked: Graphics^ FormGraphic; FormGraphic=this->CreateGraphics(); for (int i=100;i<=280;i+=20) { for (int j=100; j<=280;j+=20) { if (((i/20)-4+(j/20)-4)%2==0) DrawingBrush = gcnew Solid ...Show All
