• Game Technologies: DirectX, XNA, XACT, etc. DXGI_USAGE_BACK_BUFFER <-> DXGI_USAGE_RENDER_TARGET_OUTPUT

  Currently I specify in D3D10CreateDeviceAndSwapChain() in the buffer usage the DXGI_USAGE_RENDER_TARGET_OUTPUT flag. If I specify the DXGI_USAGE_BACK_BUFFER flag I get an error message. What is the difference between those two flags Isn't a back buffer not a render target ... I can't think of anything that makes a back buffer so special to give it its own flag :-) Enlighten me please, - Wolfgang I believe the expectation is that back buffers can be scanned out. You can bind almost anything as RT output from the pipeline in D3D10, but there is a limited set of formats that are required for scanout: R8G8B8A8_UNORM R8G8B8A8_UNORM_SRGB R10G10B10A2_UNORM R16G16B16A16_FLOAT -Sam ...Show All

• SQL Server Login Failure

  I have the default instance of sql server (2005 express) installed on my machine. I can log on with no problems using the windows authentication but I had to create a new login account with a username and password. I have added the new user using the Management Studio under the Security>Logins folder. I have assigned this new user has a server role of sysadmin and I have mapped the user as the db_owner of each current database on the server (default system db's).

• Game Technologies: DirectX, XNA, XACT, etc. Cylinder between two vectors

  I have tried rotate this thing on every axis and I still can't get it right. what I am trying to do is draw the single bond between two atoms. Does anyone have an example of the math and steps to do this. I have two atoms in my world and I have the cylinder(bond) in between. I just can't get it to rotate 90 degrees into place.If the cylinder is laying on its Z axis that mean my Z axis is pointing straight up. What am I do wrong I almost got this thing licked.... I am calculating the x, y angle for my rotation. What is the correct order to rotate these so they "connect" correctly It has something to do with the value of the angles. Can you explain how to do this or point me in a direction ;-) ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DrawableGameComponent - Need to create Texture on fly!

  I have created and drawable component but need to recreate a texture (2d sprite) on the fly from a bitmap using Texture2D.FromFile. To do this i need to access the Graphics Device. The graphics device (this.GraphicsDevice) exposed from the base class (DrawableGameComponent.GraphicsDevice) returns a null reference in both the Update and Draw (override) methods. Help Did you add your DrawableComponent to your game's component list Personally, I just make a public property in my game class (public GraphicsDevice GraphicsDevice{get{return graphics.GraphicsDevice;}}), which all my components have references to. Then, I just use game.GraphicsDevice to access the device. ...Show All

• .NET Development WMI Problem

  I've tried these two methods of accessing Win32_Account from WMI, from two separate PCs, each trying to access both itself and the other PC. In all cases the For Each loop does not execute as if the Instances collection is empty. Any attempt to inspect the Instances collection with a debugger hangs. I can run similar code in VB6 using objects and it works perfectly and lists accounts on each machine. Is this a bug in System.Management or am I doing it wrong Dim wmi As New System.Management.ManagementScope( "\\" & "somepc" & "\root\cimv2" ) Dim sClass As String = "Win32_Account" Dim opt As New System.Management.ObjectGetOptions( Nothing , New System.Ti ...Show All

• Visual Basic Access database + BLOB?

  Hopefully someone can help me with a few questions: 1) Can you manipulate Access fields to manually (using the Access interface) add images translated into binary (have a text field instead of a OLE Object field) Or does this have to be done through a memorystream/streamwriter in a seperate program 2) I don't like using BLOB to read binary text streams from a database because it causes crashes when I scroll through the entries too fast or how it requires you to read the binary from the database to a physical file then read the file using system.drawing.image.fromfile(). Can I use image.fromstream() to do the same thing without having to write to the harddrive (I would like a short example please) Maybe memorystream 3)Can you strip the OL ...Show All

• Visual C++ Problem with C++ exercise

  The exercise says: ( Employee Class ) Create a class called Employee that includes three pieces of information as data members--a first name (type string), a last name (type string) and a monthly salary (type int). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee's capabilities. Create two Employee objects and display each object's yearly salary . Then give each Employee a 10 percent raise and display each Employee's yearly salary again.

• Visual Basic Accent Characters

  Here is the problem. I am accessing data, usually using streamreader, reading a line at a time. The data is in CSV format, so I parse it with the .split. However, a lot of the text contained in the files have the funky characters, such as: 6,"Jose","Grandon","",28, However, when I pull that in, I get Jos Grandn. Which is NOT what I want. Is there any quick and easy way to allow the text to be pulled in correctly Thanks, Larry The problem is that you actually need to know the encoding in order to reliably read the text. By default, the stream reader will assume that the text is UTF-8 encoded. Maybe you could try using the default encoding and pass it in to ...Show All

• Visual Studio "unable to attach to the process" - VS 2003 VB.NET dll and VB6 exe

  I'm trying to debug a VB.NET dll that is used by a VB6 exe but every time I try to attach to the VB6 exe process i get a "unable to attach to the process" mesage from VS 2003. I start my VB6 exe project in debug and step to a break point where I have received a calculated value from the VB.NET dll. I then open my VB.NET dll project and try to attach to the VB6 exe process in CLR mode, at which point I get the message mentioned above. I've managed to do this in the past but I run into the same problem on two different systems. I've read threads where issues with netfx 1.1 and 2.0 seem to be the culprit but the work arounds mentioned there (forcing use of netfx 1.1 in app config etc....) aren't relevant to me as my exe is a V ...Show All
