• Visual Studio 2008 (Pre-release) 3D performance in WPF

  Hello I created a simple 3D model (there are two spheres in this model) with 3Ds max, exported it as 3ds file and then converted to XAML by using ZAM 3D. Then I inserted created viewport into a scene. I was using Daniel Lahenbauer's Tracball class for rotating around a model. When a model gets bigger (after zooming in), it starts to be hard to rotate around or to zoom in again, so the performance is bad. By the way, I have watched Daniel Lahenbauer's video about 3D integration into WPF on MSDN TV http://msdn.microsoft.com/msdntv/episode.aspx xml=episodes/en/20060504WPFDL/manifest.xml and there is a 3D globe demo. As I have seen, this demo has a posibility to move around the globe, and the performance is just great! So how to ma ...Show All

• Software Development for Windows Vista CardSpace Branding/Co-Branding

  Hello, I've been following CardSpace and .net 3.0 for a bit now, and having access to the private betas has really helped me understand the possibility and use of CardSpace services. I am currently working on heavily restructuring my company's corporate website which will contain a section specifically for ClickOnce deployment rollouts for our various customers. Because we are adopting .net 3.0 early (and have signed the agreements necessary) we are also planning on using CardSpace as the authentication source for accessing the ClickOnce deployment area, whereas the information provided in the user's card will determine the deployments available to him/her. One of my concerns is what is the current standing with the CardSpace team ...Show All

• Visual C++ Combo Box Question

  hi I'm making my first 'simple' application to get me started. its the basic windows Form with just a combo box containg just 3 options ' a or b or c ' ok it works fine but how can i make it remember my last selection i mean when i run the application again it shows nothing and you have to select the option all over again. registry is unneeded for this scenario and far too advanced. you can serialize the collection - so when adding items into a combo box, go through each item and add them into an array. you can then serialize the array/collection and next time deserialize the xml file to restore the objects back to the array collection. http://msdn2.microsoft.com/en-us/library/system.xml.serialization.aspx Take ...Show All

• Internet Explorer Development ActiveX Modal Dialogs do not work in IE7...

  Our product is suffering some pretty severe problems because of IE7. We've starting getting calls that dialog windows become hidden. We've heard this is a threading issue. We found out that the problem is actually much worse. Modal dialogs don't seem to function correctly in IE7. You can recreate the problem using VB6 by doing this: 1. Create an ActiveX UserControl project. 2. Add a form to the project (form1) 2. Put a button on the user control (usercontrol1). 3. Add this code to usercontrol1. Private Sub Command1_Click() Dim objForm As Form1 Set objForm = New Form1 Call objForm.Show(vbModal) End Sub 4. Build the project as an OCX somewhere on your hard drive. 5. Find your control's CLSID in regedit. I ...Show All

• Visual Studio 2008 (Pre-release) The certificate must have a private key. The process must have access rights for the private key.

  Hello All, I used makecert to generate a certificate named 'ServiceModelSamples-HTTPS-Server and installed it in LocalMachine\My store on the server.
