download-> Timer It's from first Managed DirectX release.

DLL is written in C. Im use dumpbin and function names are NewtonCreate and NewtonUpdate.

I'am trying call functions from unmanaged dll. NewtonWorld* NewtonCreate( NewtonAllocMemory mallocFnt, NewtonFreeMemory mfreeFnt); void NewtonUpdate( const NewtonWorld* newtonWorld, float timestep); NewtonWorld it's a struct typedef struct NewtonWorld{} NewtonWorld; NewtonAllocMemory and NewtonFreeMemory typedef void* (_cdecl *NewtonAllocMemory) (int sizeInBytes); typedef void (_cdecl *NewtonFreeMemory) (void *ptr, int sizeInBytes); My wrapper: public delegate byte[] NewtonAllocMemory( int sizeInBytes ); public delegate void NewtonFreeMemory ( byte[] ptr, int sizeInBytes ); public class World { internal IntPtr newtonWorld; [DllImport("Newton.dll", CallingConvention=CallingConvention.Cdecl, ExactSpelling = true)] private static extern IntPtr NewtonCreate( NewtonAllocMemory mallocFnt, NewtonFreeMemory mfreeFnt); [DllImport("Newton.dll", CallingConvention=CallingConvention.Cdecl, ExactSpelling = true)] private static extern void NewtonUpdate( IntPtr ptr, float timestep ); public World() { this.newtonWorld = NewtonCreate( null, null ); } public void Update( float timestep ) { NewtonUpdate( this.newtonWorld, timestep ); } When I try create new object i get EntryNotFoundException. Any sugesstions, help. Thx. .Net 1.1 vs2003

for(int i = this.fileList.SelectedItems.Count - 1; i >= 0; i--) this.fileList.Items.Remove(this.fileList.SelectedItems[0]);

I think that simplest way is use Font object from Microsoft.Directx.Direct3D namespace. When you have Font object you can simply draw text calls DrawText method. Sorry for my english :)

This is simple example i hope thats helps you: //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- using System; using System.Drawing; using System.Windows.Forms; //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- using Microsoft.DirectX; using Microsoft.DirectX.Direct3D; //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- class Fullscreen : Form { private Device device = null; public Fullscreen() { this.FormBorderStyle = FormBorderStyle.None; } public void InitDirect3D() { PresentParameters presentParams = new PresentParameters(); presentParams.BackBufferCount = 1; presentParams.BackBufferFormat = Manager.Adapters[0].CurrentDisplayMode.Format; presentParams.BackBufferHeight = 768; presentParams.BackBufferWidth = 1024; presentParams.FullScreenRefreshRateInHz = Manager.Adapters[0].CurrentDisplayMode.RefreshRate; presentParams.SwapEffect = SwapEffect.Discard; presentParams.Windowed = false; device = new Device(0, DeviceType.Hardware, this, CreateFlags.SoftwareVertexProcessing, presentParams); } public void Render() { device.Clear(ClearFlags.Target, Color.Black, 1.0f, 0); device.BeginScene(); device.EndScene(); device.Present(); } public static void Main() { using(Fullscreen frm = new Fullscreen()) { frm.InitDirect3D(); frm.Show(); while(frm.Created) { frm.Render(); Application.DoEvents(); } } } }
