• SQL Server clustered index fragmentation

  Hi I am testing some clustered index on a table I was working on. I put a clustered index on an int column with identity and insert some several thousand records into the table. I check the index fragmentation and notice that it was about 20%. I thought since the identity field is incremental, there would be little or no fragmentation. Is this true or is there something wrong with my server thanks Paul The fragmentation on your tables are due to updates of the variable length columns and not due to inserts. An int column with identity is the best candidate for clustered index, as there wont be any fragmentation during inserts. However, when you update your tables and increase the data size of colu ...Show All

• Smart Device Development Data Connection Options and Techniques

  Hi All, I am new to the .NETCF and actually the .NET Framework itself. I'm a MS Visual Foxpro Developer by trade and have experience developing client and web based applications using the following languages VFP9/VB6/C++6/XHTML/XML/ASP. I have recently been extremely excited by the prospect of using the ,NETCF2.0 and WM5.0 to develop a Windows Mobile based solution for one of our clients. I've done a lot of investigation into using the .NETCF2.0 to build this client solution, but not actually coded anything yet. I have created a design document detailing everything this solution should included and the language and platform to be used. Unfortunately I've hit a stumbler, my design document is far to idealistic. I have been tasked to b ...Show All

• Visual Studio Express Editions Bad variable type error (DISP_E_BADVARTYPE)

  I get the error DISP_E_BADVARTYPE when running a routine that calls up an instance of Excel. However, I do not get it on all the machines I attempt it on. The code runs fine on my development machine. I have tried it on two other machines, both of which do not have Visual Studio, and it works on one but not the other. All three of the machines are configured with version 2.0 of the .net framework and Excel 2003, so I do not think it is a versioning issue. I can't understand why this is happening, and the message I get from the JIT compiler does not help very much. I'd appreciate any thoughts on the matter. The code is below. I highlighted the line at which I believe the error occurs, based on the fact that when the program terminates it le ...Show All

• Software Development for Windows Vista Windows Service Running Word via DCOM

  Hi everyone, I developed a Windows service which uses MS Word to generate documents. I call Word using DCOM / OLE. Up to now it worked pretty well. I tested the service on Windows Vista (Beta2, RC1, RC2) and it doesn't work anymore. Opening a Document in Word crashes with varying error messages. Office 2003 sais somthing like "Not enough memory". Office 2007 sais something like "type mismatch". I guess it might have to do something with the Session 0 isolation in Windows Vista. As services in Vista now have an own session. But I guess Word has problems with it's screen. In older Windows versions, Word worked "in the dark". When I run the service as console everything works fine. Anyone an idea w ...Show All

• Visual Studio 2008 (Pre-release) New XBAP launch screen

  I have seen that in RC1 the XBAP launch screen has changed http://learnwpf.com/Posts/Post.aspx postId=710f50ba-5902-4db6-9a61-a48317b554da It's very nice, however is it possible to customize it It would be nice to be able to create your own custom loading screen - something like Flash does. Nobody's going to bother with a splash followed by another splash - especially one that is reminiscent of QuickTime! This is what bothers me about WPF in general - does one really have the freedom of UI expression that the browser exposes  It's understandable that there will be API constraints, but the demos/samples I've seen all seem to show the same pastal shades! Are control styles only going to allow one to create variants ...Show All

• .NET Development max Socket Async operations

  me wish to know how many async operations that can handle by .Net me new to socket programming, making a socket server with System.Net.Sockets and use both read/write with async for each connected clients wondering how many async operations that can handle by coz me found some article said that max threadpool are 25 thnx The thread pool limit doesn't translate directly into a limit on the number of async thread operations - you can have literally thousands of async thread operations in progress at once with only a handful of threads being in use. Despite what the documentation suggests, you don't end up using one thread pool thread for each async socket operation. (The docs used to say that this is wha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. .Net Framework 2.0/XNA Framework Integration?

  I was perusing the Microsoft.Xna.Framework classes and didn't see any for networking or scripting. I know both (and more, like reflection) are part of .NET Framework, and from http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=694459&SiteID=1 , the claim is that XNA and .NET Framework will remain independent for the time being. Will it still be possible to integrate functionality from the .NET Framework into XNA, assuming I write games for Windows, without having the two frameworks step on each others' toes OK that's good to know... Makes me wonder if there is a way to integrate a webcam into a game. My dad just got one, and I immediately thought of a team player view as part of the HUD. ...Show All

• Visual Studio Passing main report values as parameters to subreport

  Guys, I want to pass the main report fields to the subreport as parameters.

• Windows Forms How to access the publish version in the software?

  So, the publish utility has a nifty version incrementing thing. Only, the Application.Version number is completely different. I'm hoping to display the vesion (publish version) somewhere on the screen to allow beta testers an easy way to idenitify which they are using. I looked through the forums but only found ways of setting the version. What I'd like to do is just use the one already there in publish. hi running into the same problem and the doc at the location you are pointing too does not explain how to get to the publishing version from withing the application (in my case c#).

• Audio and Video Development Applicative mode (Styling)

  Hello Everybody!!!! What I get from Spec is that the Applicative mode for styling uses an Xpath Expression to select the nodes. At each tick the style is re-initialised for the node and DOM tree can change.Thus, evaluated node set can change dynamically, thus a node may/maynot have applicative mode applied to it depending on the Xpath Evaluation. Is this understanding correct. 2) The Applicative mode is over-ridden by referential and inline style. What is the usage scenario for this mode Thanx in advance. This is fine..but suppose if i have two buttons for navigation having class="navigation_buttons" Applcaive style is being used to apply style to them ..... say on basis of xpath :: class(navigation_buttons) if i add a t ...Show All
