• Game Technologies: DirectX, XNA, XACT, etc. Cannot run D3D 10 samples (Vista + Ocrober SDK)

  Hi. Cannot run samples on Vista. Some samples run fine, but they have D3D 9 code, I think. For instance, ParticlesGS says it "Cannot find compatible device" or something. Have GeForce FX 5200, 96.85_forceware_winvista_x86_international_whql.exe drivers installed, will D3D 10 be available at all Your videocards doesn't support D3D10. So, it's not possible to run D3D10 samples in HW mode/ But if you installed October DX SDK on Vista RC1 you should be able to run D3D10 samples on refrast. But it will not be pleasant speedwise. ...Show All

• Audio and Video Development coordX and coordY

  the locaiton of an applicaiton as defined in the manifest does actually seem to be froma spec perspective an animatable property... but modifying the value does not seem tto do anything. Peter, perhaps you know... shouldn't this position the application "offscreen" application.coordX = 1920; application.coordY = 1080; I was trying to show/hide an application and it's just one solution I thought I would try... I have it working by other means, but just thought I'd ask as it looks like this should have worked. Hi Scott, You are correct, this should have worked per spec. I tried a simple case of this myself and noticed some unusual behavior, so the simulator seems to have some bugs regarding th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 1.) Lock/Unlock vs. SetData/GetData and 2.) predefined vertex formats

  Two points spring currently to my mind. Is there any reason besides simplicity not to use the common Lock/Unlock mechanics I would prefer the addition of this to the API. GetData/SetData canthe simply be mapped onto this. I have a large terrain, that I tesselate into the locked buffer directly... With this new scheme I have to build a temporary array and then copy over via SetData, same with textures. On the other hand, if we have to live with this, why do we have the managed pool anymore, kind of pointless! The other thing are the predefined vertex formats... Any reason to not expose the members directly and use setters and getters instead I don't see the point here too, this just forces us to create one intermediate result and copy oper ...Show All

• Windows Forms is there any way to scan a windows form for controls and objects ?

  Hi All, Is there any way or application which scans a windows form (or even multiple forms at a time) and gives you the controls and objects prosent in the form. The similar app is available in PowerBuilder... Any help is greatly appreciated. Vivek Natani Not exactly. I'm looking to get hold of all the controls and then want to save them in the database for each form in my application. This is basically required to implement control level security on each windows form. I have tried something like: In this I'm trying to get hold of all the forms object  so that I can process multiple froms.

• Visual Studio What Class Designer?

  Are there plans for C++ support Not the service pack I can tell you that. Adding support for C++ is more work than we can squeeze into a service pack. We're still in talks as to what goes into the next version of Visual Studio. Class designer isn't #1 on our priority lists but nothing is set in stone. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Primitive design and OOD

  This question did not get any attention when I posted it with other questions so I'll try it again by itself. Primitive Design I have built a rudimentary 3D engine using good OOD where the primitives (points, polygons, lines, etc.) provide methods for their management and transformations. If I have a model with 100,000 points, each point carries the overhead of the virtual function table and whatever else the compiler does to the class. Is it more prudent to restrict the primitive class design to data only and provide a different set of methods outside of the class to manage their transformations, say, in a math lib for example When using .NET, my ref class Point3D This is a memory issue, not a proc ...Show All

• Visual Studio 2008 (Pre-release) WCF is different from remoting?

  Hi, for a long time we used remoting and an other product (genuine channels) for bypass some mayor problems of the remoting (firewalls problem, events notifications etc.) What is different in WCF now Regards Gianmaria Yes, WCF is different than remoting. WCF is a service-oriented platform that can be used for communication between heterogeneous components (in different companies, in different languages), while Remoting is limited to homogeneous systems (i.e., where both sides of the communication need to share some of the code) - notice that WCF can also be used for homogeneous systems, with good performance, as well. That implies in one of the main differences in that WCF doesn't have pass-by-reference semantics, only p ...Show All

• Windows Forms Hyperlink as a treenode?

  Is it possible to have a tree sub-node as a hyperlink, or at least to make the treenode behave like one (change the cursor to a hand etc). You can set the child nodes forecolor to Blue to represent a hyperlink, then in the child nodes OnHover event you can change the mouse cursor to the hand, and in the OnLeave event change it back to the normal pointer. Then just implement the click event to do what you want. ...Show All

• Smart Device Development Taget the different Device

  Hi, I developed an application for Pocket Pc2003. I want to target to Treo700WX. But Generally I get only 5 devices in the list (in "Deploy" window) when I use F5 to deploy and debug. Treo700WX is already added to All platforms menu(Tools-->Options-->devices--> All platforms). Can anyone tell me how to target the Treo700WX or any other device. Is there any way to find whether my Pocket PC is phone edition or not. because I want to add Vibration, LED, and SMS notification which works on only phone edition.

• Visual C++ Does closesocket call to CloseHandle? Does closesocket close "\Device\Afd\Endpoint" & "\Device\Tcp" file handles?

  Hi, I'm working on a communications component, which has been developed in VC++7 (mixed mode). When I extress-test the driver opening-sending-closing comm ports, I get file handle leaks with the name "\Device\Tcp" and "\Device\Afd\Endpoint". I've been looking for some info and it seems that I have to call CloseHandle((LPVOID)hsocket); after every call to closesocket(hsocket);. Is it true Isn't closesocket calling CloseSocket internally Thanks, Sakito.

• Visual Studio Team System How do I exclude a database project from a solution for a build

  This is along the line of other posts I've seen but, doesn't cover a database project. I have a solution with a web project, libraries, and a database project.

• Visual Studio Team System Upgrading from 180-day trial version to full RTM version (volume license)

  I just upgraded our trial version of TFS to the full version and wanted to pass on some notes about the exercise. Upgrading is pretty simple: Click Change/Remove on the entry for TFS in Add/Remove Programs on the TFS server, then enter the permanent license key in the dialog box that appears. Our TFS license was purchased through a volume license agreement, so we had no nice box with the 25-character license key on it. Instead, per the instructions elsewhere on the MSDN site, I called Microsoft Customer Support to obtain a key. The MS support rep needed the TFS Product ID in order to generate a license key. Unfortunately, neither of us could find the darn thing; after 5 minutes of searching every Help | About box we could think o ...Show All
