SQL Server SSMS scripting Stored Procedures to separate files
I have noticed that in (SQL Server Management Studio) SSMS the ability to individually script stored procedures appears to have been removed (it was there in Enterprise Manager (SQL Server 2000) and I found a comment in another thread which appears to confirm this: Steven Twitchell wrote: >We've had several requests from various sources for functionality to script objects to their own files rather than one large file. I have been scripting stored procedures to individual files and then using sourcesafe to compare databases to ensure syncronisation with a client. I can do this on one file but it does not give the same granularity in my audit history. My question is therefore: Is there a workaround in the command line / T-S ...Show All
.NET Development Windows Installer 3.1 availability in running machine as a launch condition
Hi, I wish to include Windows Installer 3.1 as a launch condition in my MSI project. In other words, the MSI will check for the availability of Windows Installer 3.1 in the running machine. If Windows Installer 3.1 is not installed in the running machine, installation will stop. There are 2 ways of doing this namely registry search and ComponentID search. However, i can't find neither the registry key nor ComponentID ( GUID ) for Windows Installer 3.1. Any ideas what's the values of the GUID and registry of Windows Installer 3.1 Thank you. Hi, The Windows Installer 3.1 is not an MSI, so you will not be able to check for a component ID. The way that Visual Studio setup checks for the existence of Windows Installer 3.1 ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Any suggestions for defining direction of partical effects on a 3D model?
Hi all: I'm still playing around with XNA and figuring out what I can do with the current state of the technology. What I want to do is have a 3D model of a spaceship that has RCS thrusters and a main engine. The RCS thrusters and main engine will all have a particle stream to simulate rocket exhaust. Somehow, I need to define the size and type of rocket exhaust, and what direction it should take, and do so within the context of the XNA framework. I presume I'd need a custom processor for the model to identify where rocket exhaust nodes are (think named invisible cubes in the 3D model, like "MainEngine" and "YawRight"), but I'm stumped on how to define the direction of the particle stream in relation to the model ...Show All

Windows Forms Accessing the value of a a DataRowView from a ListBox (How)?
I'm trying to use a form with a ListBox to select from and populate another ListBox depending upon the selection in the first. The first is populated by a query to a project resident .mdb file. I'm running into a problem when it comes to figuring out the value of the item selected in the ListBox. I can see that the object selected upon the firing of the SelectedIndexChanged event is of type System.Data.DataRowView, but try as I may, I cannot figure out how to get access to the actual values ( strings " Core" and "Special" in this case). Am I missing a necessary cast somewhere, or is it just a property or method that I missed Am I trying to use something entirely wrong for the situation Any help would be greatly apprec ...Show All
Visual Studio 2008 (Pre-release) Client side custom behaviors don't seem to work
Hi, I'm having a lot of trouble programmatically increasing the DataContractSerializer.MaxItemsInObjectGraph property on the client side. I've read the posts about increasing it on both client and service side, and have also increased the top-level ServiceBehaviorAttribute.MaxItemsInObjectGraph property and nothing seems to change the default value of 65536 used by the client. To test this, I implemented a derived DataContractSerializerOperationBehavior that creates a wrapper for a DataContractSerializer so I could intercept Read/WriteObject calls by following this example - http://blogs.msdn.com/sowmy/archive/2006/03/26/561188.aspx . By doing this I discovered that my serializer wrapper was not being created/called by the client. ...Show All
Software Development for Windows Vista Virtualisation
My application adds a dll name to the Registry HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs and creates the dll in the windows system directory (F:\Windows\system32). This works ok under XP but, under Vista I was surprised by two things: 1. The documentation states that writes to HKLM will be virtualised. It does not seem to be. Is SharedDLLs a special case 2. The CreateFile to the system directory failed. It was not virtualised. Virtualisation did occur when I wrote to other places in HKLM, as expected. Am I correct about SharedDLLs How can I create a file in the windows system directory I believe only some parts of HKLM get virtualization. It sounds like SharedDLL's i ...Show All
