• .NET Development Return argument has an invalid type - security issue?

  Hi, We have a .NET remoting application server, which works great by itself. We are currently evaluating a commerical automated testing tool, that loads the application server's API assembly and simulates a client connection to the server. However, under this scenario the proxy object does not succeed in dealing with complex objects, and we get the "Return argument has an invalid type" error in return. We figured it has something to do with security issues but couldn't find any solution. We are using a tcp binary channel with typeFilterLevel=Full. The interface for the complex object AND the complex object itself are defined in a separate assembly (ApplicationServer) then the API (ApplicationSeverAPI). Thanks, Ron ...Show All

• Software Development for Windows Vista Application Opens By Itelf Fine, But When Opened With Process it fails to load components

  Hey Guys I am trying to find out why this happens. If I try to open an application written in vb6(yah I know) under vista using a .net component using Process.Start it fails to load some components properly. But When I open it from explorer it opens up just fine and does what it is supposed to do. Any reason/explaination of why this may happen. Using Windows Vista Enterprise Edition. I am thinking it has something todo with security but honestly I don't know. Thanks for any help offered.

• Game Technologies: DirectX, XNA, XACT, etc. Spacewar Camera

  I've just noticed something about how Spacewar works which I've never noticed before and I'm a little confused. In the Evolved game the models for the players are 3D models. If this is the case, then surely the game is 3D and so there is the camera. The camera will be looking down on the models. If the model is in the dead centre of the screen (I know it can't because of the sun) then we should be looking straight down onto the top of the model. Then, if the model is moved to the far left of the screen the right hand side of the model should become visible because of the camera's perspective but this doesn't seem to happen. It always seems as though we're looking straight down onto the model. How is this done Or is it just my eyes playing ...Show All

• Visual Studio Team System Getting Associated work item for a change set

  I'm looking for any hints on what the most efficient way (through the TFS API) to get related work item for a change set The end goal I am trying to archive is; based on the position in a branch ($\MyProject\Development --> $\MyProject\UserTesting) retrieve a list of pending change sets and related work items user selects a Work Item then merge related change sets to the destination branch by selected work item To do this, I need to find a list of available work items with pending change sets for the selected branch.

• SQL Server Left Joins

  My understanding of relevant topics as well as SQL Books Online definition of left outer joins is that each record in the left table will be retrieved and where no associated right record exists then null values will be displayed for records in the right hand table but I've obviously misunderstood and would be grateful if someone could show me how to produce the required effect. My scenario is pretty simple: 2 tables DiningTables and Reservations with columns as follows: DiningTables: TBL_ID and TBL_Location - TBL_ID is the primary key Reservationss::RES_TBL_ID and RES_Diner_Name - RES_TBL_ID is the primary key There are 8 records in DiningTables and 4 records in Reservations and the objective is obtain the following output: ...Show All
