• Visual Studio Connector inheritance problem

  Hi, I got problems with connector inheritance (i'm using the RTM bits). Suppose I start from the Task Flow template. I add a connector MasterConnector that becomes the base class for the CommentConnector. When I create an instance of the CommentConnector (I associate a comment to a task), save the diagram and reopen it, the instance of the CommentConnector has doubled (two lines appear instead of one). Has anybody noticed the same problem Thanks! Mike Try this: 1. Create a new DSL using Task Flow template 2. In the DSL designer, add a new connector and make it the base class of CommentConnector 3. Hit Transform Text Templates and F5 to debug the DSL 4. In the exp hive ...Show All

• Visual C++ LNK2019

  Hello, this will probably seem very easy to any c++ guru but I'm having a problem with the error below. I'm writing a CustomAction dll in C++ 8.0 for an MSI installation. I have a function called UpdateDispatcherAppConfig and in that function I want to be able to call a shared function which is defined in a separate class file. I don't want the shared function to be exported, I have included it so I can share some of the code that is being called from two different custom actions.

• SQL Server sql 2005 downgrade to sql 7.0

  Hello people, I'm experiencing problem here that we need to downgrade our sql 2005 back to version 7.0. Apparently, all the mdf files from 2005 are recognized as "corrupted" by the 7.0 server. All my dbs are created within 2005 and i'd like to move these to the older 7.0 server. I wonder whether there are any procedure to convert 2005 mdf files so that is is compatible with sql server 7.0 or what is the most common way of solving this Any pointer would be appreciated. thx! Yes, if you want to do that more than once. If you just want to do that ad hoc you can also use the Data Import / Export wizard from SSMS. HTH, jens K.

• .NET Development Kerberos delegation problem

  I have hunted through a serious number of blogs and web pages, but I just can't get delegation to work with our WCF application. To save some space, here is a link to the source code of a small test app that I am using: http://members.shaw.ca/murraypeterson/rcstest/ You can look through the source code to see the various settings I am using (NetTcpBinding, ClientCredentialType = TcpClientCredentialType.Windows, ProtectionLevel = System.Net.Security.ProtectionLevel.None, AllowedImpersonationLevel = TokenImpersonationLevel.Delegation, etc.). The scenario for testing is simple. Two machines, both members of the same domain (machine1 and machine2). Two users, both members of the domain (user1 and user2).

• Visual Studio 2008 (Pre-release) Small Bug in FederatedSecurity sample :: Off by one

  Hi, I based an STS on the FederatedSecurity sample that is on netfx3.com http://wcf.netfx3.com/files/folders/authorization/entry1954.aspx I just found a bug in it. When I use this to find the claim, I find nothing set.FindClaims(ClaimTypes.Thumbprint, Rights.PossessProperty) A bit of debugging shows that the claims do contain this information, but that it does not match the value of ClaimTypes.Thumbprint. There is an extra whack in it between "claims" and "Thumbprint". http://schemas.microsoft.com/ws/2005/05/identity/claims//Thumbprint In fact the whole set seems to have extra whacks (below). http://schemas.microsoft.com/ws/2005/05/identity/right/PossessProperty : http://schemas.microsoft.com/ws/20 ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Radiosity Light Maps Generator

  Hello, I wish to light my worlds (about 200k triangles) with light maps computed by a radiosity processor. However, radiosity calculation is incredibly slow for medium/large worlds and so acceleration technique are needed. Computing lightmap on the GPU is a way to speedup the process, but I haven't found any far decent tool on internet (I have tried FSRad, but run on CPU and can't handle so much triangles). Any suggestions Thanks. P.S.: XNA include tools like this Not real-time... I means classical precomputed lightmaps (offline), but... with a radiosity processor able to handle large worlds and fastttttt... in order to permit a fine tuning of lights... Can I use D3DX PRT library to do this ...Show All
