• Game Technologies: DirectX, XNA, XACT, etc. Rotating sprites center

  I'm new to directx programming and i'm writing a simple program to help me learn. I'm using sprites and i'm trying to rotate the texture based on its current heading (the sprite is moving around). Now when i try to rotate it using a matrix, it seems the matrix is too big. My texture is only 32x32, and when i do the transformation, leaving the rotation center as NULL should set it to be the top left, according to what i've read. However, after experimenting because it didnt work, I found that if i set the center to be close to the window's center, or some larger center, it seems to fix it a bit. So it seems to me that the matrix is too big for my texture. I don't know if there is any way to set the size of it If you would like code I can ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XACT Cue Playback Latency vs. DirectSound

  I'm currently working on a piece of sound software that performs realtime quantizing based on eventual in-game actions. Since I need to play sounds on beat, it's important that the time from the Play() call is made on a buffer/cue to the time it actually starts coming out the speakers is very low. XNA and XACT look like they're a great framework for making games. For the application I'm developing though, minimal sound playback latency is critical. Has anyone at Microsoft measured any additional overhead caused by using XACT over DirectSound (in either MDX, or C++ DX9) XACT on Windows XP has some additional latency on top of DirectSound. XACT has its own software mixer, and (on XP) it takes that outpu ...Show All

• .NET Development file opened exclusively error, re-use datatable when new text files are created

  I am writing an application that watches a folder for new comma-delimited ascii files. Whenever one is created, I read it into a datatable, compute some statistics, write them to a log file and get ready for the next file. My code works great for the first few files, but starts throwing unhandled "file opened exclusively by another user" oledbexception errors after 4-5 files. The error always occurs at the adaptertext.fill(dtModel) line. Any help is much appreciated! My code is as follows: '**** Private Sub newasciifile(ByVal source As Object, ByVal e As System.IO.FileSystemEventArgs) Dim selectfilename As New System.IO.FileInfo(e.FullPath) Dim ConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Sour ...Show All

• .NET Development Creating processes in a suspended state?

  I need to use Win32 job objects to corral a bunch of child processes. First problem is that there is no concept of jobs in the BCL. Strike 1. Why not Ok - not that big a deal - the stuff I want to do isn't that hard to pinvoke a bunch on - mostly just IntPtr handles anyway. Second problem is that there is no way using the Process class to create a child process in a suspended state so that the handle is valid, but it isn't running yet. Strike 2. What a mess - the existing code I have to modify heavily uses the Process class. and that little addition to the ProcessStartInfo of a bool CreateSuspended would have been so handy. Argggh. The obvious solution is to P/Invoke CreateProcess() so ...Show All

• Smart Device Development Windows hooks on WM 5.0 for Smartphone

  I am aware that SetWindowsHookEx is not meant to be used for smartphones on WM 5.0, though I notice the function is available in coredll.dll in both Smartphones and PocketPCs. I also notice that limited usage can be achieved on PocketPCs (yet, it's all undocumented), while I had no success while playing with it on a smartphone. What do we do in that case I want my application to be able to receive press events (incl. the events coming from 0-9 keys) while homescreen is in foreground, and to be able to execute a code before any other application (for instance a dialer) handles the events. What do we do for it when SetWindowsHookEx() is not available Btw, is SetWindowsHookEx() now considered to be a *privileged API*, or it is not availabl ...Show All

• Smart Device Development prob with syncronizing socket send and recieve. Plzzzzzzzzzz help!

  Hi, My app uses a socket connection to send and receive from a remote server. I've very serious prob with the socket, i.e. synchronizing send and receive on that. The app actually creates seperate threads for sending and recieving. The receive thread, which we call as cmsThread, keeps polling the socket, by calling receive on the socket periodically. From the time i started this app, i had probs with synchronizing the send and recieve. Previously i used lock(this) for both send and recieve, in the socket class that i created. This made my app look hanging when more msgs were sent. I realized that this was because of blocking the thread in send and receive. So i removed the lock statements altogether. But now i've a ne ...Show All
