• Game Technologies: DirectX, XNA, XACT, etc. Writing raw texture data to file

  Im trying to write the raw texture data to a file. Im doing this by locking the rect of the texture and then using WriteFile to write it to an opened file. texture->LockRect(0,&pLockRect,NULL,D3DLOCK_READONLY); WriteFile(hFile,pLockRect.bits,Width*pLockedRect.pitch,&dwWritten,NULL); Is this the correct number of bytes to write When I have large textures to write WriteFile fails with ERROR_INVALID_BUFFER. Has anyone got any ideas It depends on the format of the surface you are locking. Take a look at the SDK docs (D3DLOCKED_RECT). It describes there the meaning of the "pitch" parameter. At a first look, I can see that you should use Height * Pitch instead of Width * Pitc ...Show All

• Visual FoxPro How to selectonentry an edit box in a grid.

  Hi; I have a grid with 2 columns: a txtbox and an edtbox. For some reason the edtbox won't SelectOnEntry no matter what I do. I've tried to set selectonentry for the column and the control itself. I've set the format to "K" I've set DynamicInputMask to "K" highlight is .T. Nothing works. Any ideas >> No. All I'm trying to do is to selectonentry the memo field which the user tabs into. But in the process, I don't want all the other rows to show 'memo' as their content, but rather show the text of the memo field. Ah, I see! LEt mne look at this, I am sure there is a way ...Show All

• .NET Development Always inherit from MarshalByRefObject?

  When using .NET remoting, it's obvious you must have some way of passing object values and refrerences to the remote server; but should you apply one of these practices always as a matter of course public class Password : MarshalByRefObject { ... } [ Serializable ()] public class Password { ... } I have noticed that the .NET framework inherits most (if not all) of it's objects from MarshallByRefObject. I seem to find myself now doing the same. Also, when is it best to use Serializable() instead of MarshallByRefObject Your reply didn't directly answer my question. My question was rather "is it good practice to always inherit from MarshallByRefObject " rather than the questio ...Show All

• .NET Development Finalization aborted when taking locks inside finalizers

  Hi, its me and my finalizers again. In my quest to get rock solid and predictable shutdown behaviour I stumbled accross the bizarre phenomen that when I take locks inside a finalizer the whole finalization stuff during shutdown is cancelled. Is this the expected behaviour or did I miss something using System; using System.Collections.Generic; using System.Text; using System.Threading; using System.Runtime.ConstrainedExecution; namespace LocksInsideFinalizers { class Other : CriticalFinalizerObject { ~Other() { Console.WriteLine("~Other called"); } } class Program { string myName; public Program(string name) { myName = name; Thread t = new Thread(ThreadFunc); t.IsBackgroun ...Show All

• Software Development for Windows Vista Drawing over fullscreen video from AudioVideoPlayback

  I've spent some time trying to render text or even a control on top of video being played at fullscreen using the AudioVideoPlayback namespace without any luck.  Originally I was aiming to have a transparent control on top of the video, but if I can get text on top, or any control (transparent or not) I'd be happy... Can someone point me in the right direction   Perhaps provide an example of something similar Hi, After I setting windowless mode, how can I make this setting work, or make the video draw on my window farming ...Show All

• Visual C# Issues with C++ to C# migration

  Im working on a device application (no this is not a device related question, just happens to be the context of my issues) and I continuosly get an error stating "Exception from HRESULT: 0x8005000A" Invalid Advise Flag. Any ideas on what this means or what I should be looking for I am also confused on the use of CreateEvent.

• SQL Server Test - populating tables with dummy data

  In 2000, BCP seemed the way to go. DTS packages would also work. My question is, in 2005, what is the best choice I seem to remember that BCP ignored all referential integrity constraints, and applying them afterwords was a royal pain. I'm not a BCP expert by any means. Running this at the command line means using the DOS prompt correct What is 2005's answer to this No one answered this question, how do people normally insert dummy data into tables I mean, where does the data typically come from what process is used to insert the data Note: This is for testing purposes, eventually to be tested in a Web-based front-end which I know nothing about. thx, Kat ...Show All

• Windows Forms 2D grid

  As i said in a previous post, i am writing an editor where i can "draw" maps using tiles. The tiles will be put on a 2D grid, each tile an object, and i am thinking of using the TableLayoutPanel and fill all the cells with picture boxes which in turn will hold the tile itself. However i can't seem to find a way of fixing the cells height and width, they remain dynamic. So, how do i make all the cells in a TableLayoutPanel fixed in width and height. Or maybe i should approach this project a whole other way Thanks for the reply nobugz, the project im working on is actually a map editor for a tile based game, in my program i can (in the future) "draw" the map in the editor and save it to a text file that the game engine itself ...Show All
