• Game Technologies: DirectX, XNA, XACT, etc. DrawSprite speed up

  we have our great set of Gui controls based on CustomUI smaple from DX SDK but one update: we can load our texture for some controls: Panels can have own Textures. all CustomUI  sample + framework from DirectSDK use Sprite.Draw method , but I was thinking what if use vertextbuffer + texture object to draw our images/controls, will we get gain on this or no, does Sprite.Draw method  - faster. ALso, what are benefits here if we'll  use Shaders(effects) to render our GUI here, thanks. waiting for reply I havent used sprites lately but if they havent improved since then you are better off drawing your own quads, spr ...Show All

• Visual FoxPro MSGraph.Chart.8 control

  I need to make charts. I started with MSChart Control and so far I've accomplished almost all I wanted except for one thing which totally eludes me. I need a simple line chart, not columns or a pie. I need to display a row of data like DJIA or similar indices with no additional vertical bars or other embelishments. The curve comes out nice but a lot of space on the chart is wasted because the curve is being plotted too high on the chart in vertical direction. I have tried to manipulate MSChart.Object . Plot . Axis ( VtChAxisIDY , 1 ). ValueScale . Minimum value but it is not responsive at all. I do not know why: perhaps other paramete ...Show All

• Visual Studio Team System TFS RC1 Install - Account Related Errors

  Hi There, I've been trying to install TFS RC1 for several days and must confess to be running out of strength having encountered (and to some extent) solved a number of different errors. Environment is: Fresh Install of Windows Server 2003 SP1 Followed by a fresh Install of SQLServer 2005 (2 attempts) Windows Share Point Services SP2 (3 attempts) TFS RC1 (many attempts) We are running a Samba Domain server with LDAP.

• Software Development for Windows Vista Error debugging a workflow

  Hi, I have the RTM version of VS 2005 installed with the 2.0 framework and the November CTP of WinFX and specifically the WWF VS integration. Everything seems to work fine except I get an error when trying to debug a workflow: "Error occurred while Loading Workflow An error occurred while loading the workflow. Please correct the following error and try reloading the document to view the Workflow. Attribute 'Class' not found on the root activity." This happens for even the most basic of workflows if I simply create a sequential workflow project and then add a "Hello World" code activity, set a breakpoint on the activity and debug.

• .NET Development .NET Framework 2.0 dependencies

  When I install .NET Framework 2.0 on Win2000 SP1 machine, a popup dialog appears saying that it require MS Installer 3.0.  When I install MS Installer 3.0 on that machine, it then require Win2000 SP3 which is big group of components. I am surprised when I try to deploy my .NET 2.0 application to customer's Win2000 or lower computer, there are big group of prerequisites needed.  Honestly, I am not dare to do Win2000 SP3 upgrade to customers' computers. Any suggestion I don't think we can draw any conclusions about what the shipping Framework 2.0's final requirements will be.  It is possible that the curren ...Show All

• Visual C++ VS2005 debug CRT does not report file/line info for heap corruption

  Hi hyslopc! I just ran a test of the VS 2005 beta 2 debug CRT library _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_DELAY_FREE_MEM_DF | _CRTDBG_CHECK_EVERY_1024_DF | _CRTDBG_CHECK_CRT_DF); char * Test = new char [3]; Test[3] = '\0' ; // Cause memory corruption delete Test; This results in a dialog box being shown which says that a heap overwrite occured with allocation X at location Y.  No really useful information such as the filename/line number where the allocation occurred, or the number of bytes allocated. If I jump into the debugger at that point, ...Show All

• Visual J# Express Debugging of J# Browser Controls

  I'm trying to debug a J# browser control using Visual J# Express Edition. My control is embedded in an html page. Since the output of my project is a class library I cannot start it directly.

• .NET Development How do you call methods inside an executable from another executable?

  Is it possible in .net to reference .exe and call functions in the executable   If so, how   It seems you can only make references to .dll (class libs).  I know it is possible in COM and preious versions of VS.  It is so powerful, I can't believe it if it isn't possible yet under .NET. Visual Studio .NET 2002/2003 does not allow executables to be used as references, whereas Visual Studio 2005 does. However, you can work around this in 2002/2003 by temporary renaming the executable to end in .dll, add the reference and then at runtime the Framework will look for an exe or dll. ...Show All

• Visual Basic Class Structuring

  I have a set of routines and functions I wish to group together under a class.  I have spent some time looking around the Internet and have figured out how to set and use a basic class.  However, I need to do more than what I have seen and without training or access to books to tell me, I'm stuffed. If somebody could give me the basic structure for the following, I'll hopefuly be able to take a look and expand upon it to cover my needs. The class accesses a sql database and returns useful information to any applications which will inherit the class.  As the database may move to a different server in the medium term, I want t ...Show All
