• SQL Server Logical fragmentation

  Hi: when does a table not show any Logical fragmentation 1). Is it possible if the table has only non-clustered indexes and no clustered indexes, it wont show any logical fragmentation at all or shows less logical fragmentation . Also what is the difference between logical fragmentation and Physical fragmentation of a index .Is there actually something like a physical fragmentation for a index Thanks AK Logical fragmentation only applies to indexes (clustered or non-clustered). If the physical location of key orders from leaf level of an index is the same as physcial page order in the database files, then logical fragmentation is 0. You can find more information in Book Online from DBCC SHO ...Show All

• Visual Studio Tools for Office opening a Word document

  I want to open a Word document and then be able to tie into its events. If I create a new Word Document project in Visual Studio, then I get this kind of control over a document because it creates a Microsoft.Office.Tools.Word.Document. I know that I can call (Microsoft.Office.Interop.Word.Application instance).Documents.Open() to open a document, but this returns a Microsoft.Office.Interop.Word.Document object, not a Microsoft.Office.Tools.Word.Document object, so I don't have access to all of the events and properties that I need. Is there a way to get a Microsoft.Office.Tools.Word.Document object for an existing document that I load up from disk There must be a way because the Word Document project seems to be doing this, but I can't f ...Show All

• Visual C++ The com component problem when upgrading from vc6 to vc2005?

  When I upgrading a vc6.0 project into vc2005, there is the following error:" Error 31 error C2039: 'BorderEffect' : is not a member of '_Chart' d: etrumform.cpp 1034 ". The code is as follows: _ChartPtr pChart; pChart->BorderEffect = BorderEffect_None; I check the definition of _ChartPtr as follows: typedef _com_ptr_t<_chart>_ChartPtr; I think that it is a com component here, can you tell me how should I solve this problem I appreciate your help. COM programming is the same under both VC6 and VS2005--forward compatibility is very important. I think you're looking for a high level solution to a problem that is probably in the actual definition of _Chart itself. Where did you get ...Show All

• .NET Development how i can cancel a regex.ismatch() when it's working

  Regex re = new Regex(text, RegexOptions.IgnoreCase); if (re.IsMatch(text)) //it will be working for long time if the regex is not very right ..... i can't have a timeout property for the regex member,so how i can solve this I know this doesn't answer the question, but it might be that the regex, for lack of a better term, is malformed and leads the processor into long processing times or a loop.... Could you give us the regex and example text on what it is supposed to look for ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is there any way to tell if a sampler has a texture attached in shaders?

  Is there any way to tell if a sampler has a texture attached in shaders The default behavior is getting black when no texture attached but I want it to be some other color. I agree that assuming stuff like this is a very, very bad idea, and should never be done under any circumstances. However... I was thinking about this very thing just the other day. It would be VERY useful if sampling from a sampler with a NULL texture was guaranteed to return white (or better yet, some value you could set in a register somewhere.) It would mean you didn't have to have different shaders for textured/non-textured objects. Sure, you could work around this by just setting a small white texture instead. But if the driver is ...Show All

• Visual Basic Getting the caller procedure name from the called procedure

  Hello, I'm developing in a VS2003 environment using VB.NET. I suppose the thingh I'm trying to do is possible and has a trivial solution ... but after searching all day long the Internet I cannot figure out "how"..... Is it possible to get the name of the caller procedure (or function) from inside the called Procedure (or function). If yes what Class/Variable do I have to refer to I mean ... Proc_A calls Proc_B with no parms and Proc_B should be able to say " Hello Proc_A ... ask me for anything you like and I'll do it for you .....

• Game Technologies: DirectX, XNA, XACT, etc. For DX10, will there be a Managed API other than XNA?

  There are several things missing from XNA that make it only useful for specific scenarios; I understand this is intentional, and I agree with the move to produce a x-platform game-dev api that keeps focused on specifically what it is meant to do. But it looks like XNA is meant to completely replace MDX in the long run. Does that mean that any developer looking to work outside of the box a little, to explore new solutions, or to produce applications that don't belong under the typical 'game' umbrella, will be forced to use the low level DXSDK api's Currently, the only way to leverage certain kinds of functionality (for example, real-time audio data generation and manipulation) in managed code, is to use MDX. XNA will not provide access ...Show All

• Smart Device Development Embedded Windows Media Player Control in HTML Page...Such a problem !

  Hello, In my program, I generate an HTML page, within a windows media player control, thanks to the <OBJECT> tag, with the "CLASSID:CLSID=22D6F312-B0F6-11D0-94AB-0080C74C7E95" type. The problem consists in the video display.

• Visual Studio How to make RDLC Column Widths adjustable depending on data?

  Is there a way to make the data in report table (and matrix) to shrink to fit (as in a normal html table when no width is specified). The client requirement is to accomodate as much columns as possible on the report. The CanGrow and CanShrink properties of textboxes in the table do not help me with this. The width of the textboxes seem to be fixed in the report. Any help would be appreciated. Thanks in advance. Hi, I am facing the same problem what you faced. Do you able to find the solution for this Can you share any work around for this problem. Thanks. ...Show All
