• Game Technologies: DirectX, XNA, XACT, etc. Beginner shader question - I'm missing something obvious

  Hello, all: I'm working on a simple space sim, and I'm trying to render a weapon shot using an HLSL shader. I haven't used a shader before, so I've read through a bunch of code samples, and picked up a couple of books, so I *think* I (kind of) understand what's going on with vertex and pixel shaders. The problem I'm having is that when I enable the vertex shader the mesh I'm rendering is drawn in black. If I disable the vertex shader (comment it out), the pixel shader outputs the color I expect. I've tried it with a mesh I created and with a mesh created via Mesh.Sphere with the same result. Here's the shader code (it's almost an exact copy of the simple pixel shader code from MDXInfo). As you can see, it's totally simple: uni ...Show All

• Community Chat your computer is ready to compute

  as many know when you don't have the latest CPU you'll have to wait when your computer is ready to compute. also many handicapped persons, which area doesn't matter, are waiting when their pc is ready to compute. all other persons watch the LED of their HD, when it goes out. and watch the mousepointer becomes to standstill. whatever, the case is, you'll have to WAIT..... why don't you make a neat little program that can be implemented in any MS OS, Vista included, that tells you by sound and vision: YOUR COMPUTER IS READY TO COMPUTE. the idea is seen on Startrek serials which were made by the fabulous Gene Roddenberry. the computer on board of the Enterprise told their crew members that "she" was "rea ...Show All

• Visual Studio Any way to prevent language service "undo grouping" editing actions?

  Hello, The different language services in Visual Studio try to group distinct input events into undo groups. For example, if you type a space somewhere, move around the file, go back right after the just inserted space, and type another one, they will be "grouped". That means that when you try to undo, both typed characters will be 'undone' at once. I would like to prevent this from happening (the issue is a bit more complex, because I open LinkedUndo's around each of the actions, but the language service still groups them and leaves me with "empty shell" LinkedUndo's after the fact). I tried to open and close a CompoundAction both on the View and on the Buffer, but the language service is still able to ignore this. Is ...Show All

• Software Development for Windows Vista Custom Human Workflow Activity

  I am in process of developing my own human workflow activity by extending Activity base class. But there is one scenario that I am unable to solve. Let us suppose we have 2 different human steps in a workflow process, say step A and step B. The workflow gets routed to human step B after completion of human step A. Depending on some business rules I should be able to reactivate step a. How can I achieve this The default activity automaton does not allow an activity to be brough back to Execution status when it is already closed. Thanks for all the help in advance. Bala This isn't nice but might work: put A, B and C in a while activity. A and B each carry a boolean flag. The flags are set to false in the beginning. A and B ...Show All

• Visual Studio 2008 (Pre-release) Serialization error.

  hi friends, I want to serialize a System.Windows.Documents.Paragraph object and pass it to another machine which will deserialize it.

• Game Technologies: DirectX, XNA, XACT, etc. How can I directly stop drawing a pixel?

  Maybe it's a very essential question but... Which is the statement in the pixel shader to stop drawing a pixel Stopping it that way would have any negative effect Thanks Dont think theres a way to do this directly. The pixel shader is called for every pixel and always must return a value - which will be your color. You could always set the alpha in this when you dont want to render and enable alpha blending, although this could leave you with artifacts if your objects arent rendered fromt he back to the front. What is the result you are after (ie description of what your trying to ultimately achieve) N ...Show All

MarcD wrote: Dim frmNewForm as new Form2() frmNewForm.Show() also frmNewForm.Show(Me) or frmNewForm.ShowDialog() also frmNewForm.ShowDialog(Me) If you use the ShowDialog method the user has to close Form2 before being able to go back to form1 If you use the Show method then both forms can be seen and accessed at the same time.

  Hi I have a database with one table containing: - id (int) - name (string) - date (DateTime) Now I fill a DataSet with the data in the database using OleDbDataAdapter .

I can start and stop it fine but the problem when executing a custom command i get and error "Cannot open SeekWare service on computer '.' " SeekWare is the service name. Someone told me that he fixed this problem by installing with the acount property set to "User" . But i want the service to run no mater which user is logged on. Thanks.

• Visual Studio Team System Can a Work Item Type be disabled?

  I have a situation where work items were migrated from ClearQuest as a "Defect" work item type. I need to prevent new "defects" from being created since we are using the default work items (task, bug, etc) going forward, but I still need to see the old defects for historical purposes.

• Visual C# Converting Visual C# to Visual Basic

  Hello everyone! I am new here at the forums.  I have a simple question. Does anyone know of a free accurate program that converts Visual C# coding to Visual Basic I tried using Google before posting, but I can't seem to find one. At least a free one... Thanks for the help! - Jason - Also note that the commercial converters will have free trial or demo versions. Although they'll have line limits on conversion, the conversions will be much more accurate. Overall, you'll save more time.
