• Game Technologies: DirectX, XNA, XACT, etc. Does (Can?) Update() get called more than Draw()?

  I'm not completely familiar with game loops, but up until now, I've assumed the seperation of the Update/Draw methods in the default class are just to make the code nice, and Draw would always be called once after each update. However... If that's the case, and my framerate sucks, my reading of the keyboard etc. may well miss keypresses. So, is it possible (or common) for the Update() method to be called more than the Draw() method I'm assuming the timeElapsed stuff was so that the framerate doesn't affect the speed of the game, but that suggests that Update/Draw are locked together. When I play WoW on my desktop, it often drops to 5-10fps. If my XNA app ran at that rate, I could see keypresses being misses easily. What can I d ...Show All

• Visual Studio Tools for Office Which suites will this work with?

  Hi, We dismissed the old VSTO because it would only work with a limited range of Office 2003 suites, specifically the ones with XML support. Two questions: 1. Can we use VSTO 2005 and know that our solution will work with *all* suites from the Office 2007 range 2. VSTO 2005 supports Office 2003. Is this still limited to the professional versions of Office 2003 or does this new release also support all Office 2003 suites If the answers to both of these is yes then we will start taking this more seriously than we are...yes to number 1. only is a great start - but still 3 years too late. There is nothing on MSDN that clarifies this - it's not mentioned that is doesn't support it. Many thanks Steve ...Show All

• SharePoint Products and Technologies WSRP or "remote webparts"

  Is it possible for MOSS 2007 to produce WSRP My goal is to use WSS/MOSS as a webpart repository and have one or more frontend servers to render the webparts configured in WSS/MOSS. Is this possible That's not really the architecture of the system. So what is the end goal here Avoiding paying for MOSS but serving content The architecture would be that would would create your web parts and deploy them to each front end web server, if each front end web server shares a content database, you can display information from any site on any server. If the goal is to serve content inside the web parts and manage it in a central place (ie, place the same content on every page and edit it in one place) then you would look at "Shared ...Show All

• Visual Studio Team System Can't delete folder from the Source Control (get the folder on gray)

  Hi, I get sometimes very weird error when I'm trying to delete some folder from the source control. I get the folder on gray and I can't update the source control window to show me the source control tree without this folder. I tried to do many things to solve this problem - refresh the page, close and open the IDE but nothing really helped, the only thing that really helped me was to sign - in as tfssetup and then to delete again the problematic folder and get entrance again as default user. Just to mention that I am administrator on this machine. Can any one explain why does it happen Thanks in advance, That's right they are set in different places over the file system, Beca ...Show All

• Visual Basic Reading a textfile into a listbox

  Using VisualBasic 2005, I am trying to save the items of a list box into a textfile so that the next time I load the form, I can read the items from the textfile back into the list box. My code, as shown below, gives me no errors, but the only thing that shows up in the listbox is “System.Windows.Forms.Listbox+ObjectCollection” I have spent hours researching and trying other methods, but this code is the closest I have come to being successful. I will appreciate any help or insight that someone can offer.

• .NET Development Error "ExecuteScalar requires an open and available connection..."

  H all, I have an application that retrieves data from a local SQL2005 (Standard edition) database frequently (e.g. more than 10 times/second normally). It usually works fine. However, if the program was paused for a while (e.g. for a few hours) by a pop-up error message box or an Sleep() statement, it generates the following error message when its data processing resumes: " ExecuteScalar requires an open and available connection. The connection's current state is closed ." The application is coded with C# using ADO.Net. The connection is OleDbConnection. It seems there is some timeout process that I do not know. Could anyone offer any hint Thanks, hz Thank you all for the information! Firstly, let ...Show All

• Internet Explorer Development IE7 embedded webbrowser control and SWF/PDF files

  My app embeds a webbrowser control. One issue I notice after installing IE7 is that if I browse directly to a SWF or PDF in the webbrowser control, the page is blank. If I browse to an html page that embeds a SWF, it works fine. Browsing directly to a SWF or PDF in my embedded webbrowser control works fine in IE6. Am I missing a flag/setting when creating my webbrowser control BTW - I'm using WinXP SP2. If I browse to the SWF or PDF in standalone IE7, it works fine. Jake- A KB article is coming out shortly about this issue. However, here's the short version: This error is occurring because of an unforeseen dependency between an IE6 XPSP2 security feature ( Local Machine Zone Lockdown ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Maximized window frame rate issue

  In my game, if I resize the window to fill the entire screen without actually maximizing the window, it runs at 59 FPS. If I hit the maximize button for the window, which isn't really changing the window size at all, since the window is already filling the screen, my FPS drops to 24 FPS. So with the same size window and the same code, the only difference is that the window is maximized. Any idea why this might be happening Bill Well as you probably know, Windows Vista is currently an unsupported platform for XNA as stated in the FAQ: http://msdn2.microsoft.com/en-us/xna/aa937793.aspx I think it's a significant possibility that Vista is the reason for the problem. Have you tested a release build as opposed to a debug ...Show All

• Internet Explorer Development IE7 Tabs

  I am looking for a way using the SendMessage API or something along those lines to activate a different Tab from an external application, so I can detect if a URL is already open and restore that instance of IE and automatically switch to the proper tab. Hi Michael, There are not specific APIs for automating tabs in IE7. You can you accessibility APIs to activate different tabs. We are looking at this area for future development and it would help to understand exactly what you'd liek to see here. Thanks -Dave ...Show All

• Visual C++ Getting bug report support from Microsoft

  I have recently reported a private bug to Microsoft, a "C++ CodeDOM parser error: Internal Error", which blocks my efforts to continue component development for one of my components in C++/CLI. The bug was reported a week ago but has evidently not been reviewed by Microsoft. The bug is detailed at http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=671820&SiteID=1 on this site.

• Game Technologies: DirectX, XNA, XACT, etc. DXT compressed Textures

  Hi, in general it looks like there are the same DXT texture compression formats as for DX9. I assume those compression formats do not work with the new DXGI_FORMAT_R9G9B9E5_SHAREDEXP & DXGI_FORMAT_R11G11B10_FLOAT formats In real-life (TM) I always have to store texture data in DXT compressed formats ... if I want to opt for a better color quality in compressed formats, nothing seems to have changed between DX9 and DX10 ... is that correct Thanks in advance, - Wolf Yes there is no block compression for floating point textures. ...Show All
