• Visual C++ This code snippet makes no sense...

  I've come across some code syntax I've never seen. It compiled, but I don't know how, or what it even does! I've been reading a book about DirectX, and in one of the examples, this little piece of code was present: D3DXMATRIX *D3DXMatrixIdentity(D3DXMATRIX *pout); "D3DXMATRIX" is a type, of course. And "D3DXMatrixIdentity" is a function, of course. Now I don't see how this works. Okay, to break it down, first we have a type, which is D3DXMATRIX, then we have the indirection-operator (which I assume is a pointer), and then we have a function (perhaps a call) with a new D3DXMATRIX (pointer) as it's only parameter. How the heck does this work It isn't just a regular function-call. It isn't a function-call that' ...Show All

• SQL Server Implementing "preconditions"

  I have about a half-dozen insertion tasks that depend on a condition: SQLServerProcessDate == OLEDBprocessDate. If the task executes early, old data gets inserted and needs to be backed out later on. (This happens about two-three times a month.) The jobs start at 8:00 PM, but on occasion processing runs late. In order to make the task intelligent enough to not insert old data, I've thought of a couple options: 1.) Separate scheduled job runs continuously, comparing process dates. When the dates match, it sends a message to the other jobs. Pro: less repetitive. Con: another scheduled job ! I'll have to learn the message queue task; a little bit complex; flood of database activity on message reception may slow system down 2.) Compare the dat ...Show All

• .NET Development Configuration tool is not part of the .NET 2.0 runtime package.

  The configuration tool is not part of the .NET 2.0 runtime package. When a user installs the .NET 2.0 runtime package IN ORDER TO RUN A PROGRAM written using .NET 2.0, that USER would need to use the configuration tool in order to trust the assembly that he is planning to run. The configuration tool should NOT be a part of the SDK; it should be part of the .NET 2.0 runtime package. I tried installing .Net 3.0 Runtime Package and still was not able to get configuration tool and i won't like a user to install 350+ MB of SDK to use my DLL. Can anyone suggest on how i can override this problem. I could not find any solution other than below. But at least it works. There is a way to create a ...Show All

• Software Development for Windows Vista Problems with Rehosting work flow designer in ASP.NET example

  Hi, I am trying to run the example from http://www.masteringbiztalk.com/blogs/jon/PermaLink,guid,28601754-c305-4597-a0a6-48f32be1eddb.aspx . When I try to run the page AsAControl.aspx it doesn't show the designer on the screen. When checking logs on IIS, I found that I was gettign error 500. Running default.aspx doesn't show the workflow image. Any ideas Thanks. Hi Jon, I've downloaded and looked at your sample code for displaying the workflow image in a webpage. I'm not interested in providing editing capabilities in the web page, so my rehosting page simply needs to provide a readonly view of a workflow instance.

• Game Technologies: DirectX, XNA, XACT, etc. GameComponents, Collections and Designer

  Hi, I just provided some feedback about this behavior in GSE and I wondered if this was annoying only me... Basically, what I do is creating a GameComponent in a Game Project. To this GameComponent, I am adding a collection property (Can be anything from List<T>, Dictionary<TKey,TValue> or whatever other IList or IDictionary based one...). When I'm adding this GameComponent (after a full build of course) to the Game designer area, I then can see my collection as a property in the PropertyGrid. However, what feels strange about it, is that when I add an instance of any kind of object, it is created and added in the scope of the Game instance (in its InitializeComponent method). Is this normal behavior Thanks ...Show All

• SQL Server Copying database using "Copy Database" - still failing after SP2

  I am struggling with the "Copy Database Wizard" in SQL Server 2005. I am used to working with DTS to copy data from one server to another, but with the new tools, I am having serious problems (in fact, it's unusable) 1. When copying a database using the "SQL Management Object" method, I always get errors concerning logins. If I select not to copy logins, I get errors "sp_grantdbaccess failed". If I do select to copy logins, the logins can't be created because the machine names are different (one the source machine, the login is called MACHINE1/mylogin, but on the destination machine, such a login cannot be created) 2. For small databases, I ALWAYS get the error "CREATE DATABASE failed. Primary file must be at least 3 MB to accommodat ...Show All

• Visual FoxPro Add Fields To Word

  Hello out there: I'm trying to figure out a way to add a field to a Word document so when the document is called using Word Automation in Visual FoxPro, I can place a FoxPro table field value in it. I've seen it done before, I just can't figure out how to do it. Could someone out there help me Thanks. Bob, There are more than one ways. Word field, word mergefield, word form field, bookmark etc. Depends on what you're doing really. For a single document bookmarks seem to be easiest. For multiple documents mergefields sound to be more effective. If you would add fields yourself as a template then from VFP: oWord.Documents.Open( <fulpath to your doc> ) oWord.ActiveDocument.Variables("varname").Value = &quo ...Show All
