I've finally figured out why my code wasn't working... I had to set the view transform and turn off lighting. Then I had to put in the BeginScene(), EndScene(), and Present() calls when rendering. Here's the new version of the GameForm.cs file: // ************************************************************************************************* // ***** Project: 2D DirectX9 Test // ***** Author: Thrash505 // ***** Created: 07/24/2008 // ************************************************************************************************* // ************************************************************************************************* // ***** Using Directives // ************************************************************************************************* #region Using Directives using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Windows.Forms; using Microsoft.DirectX; using Microsoft.DirectX.Direct3D; #endregion namespace _2D_DirectX9_Test { // ********************************************************************************************* // ***** GameForm Class // ********************************************************************************************* #region GameForm Class public partial class GameForm : Form { // ***************************************************************************************** // GameForm - Attributes // ***************************************************************************************** #region GameForm - Attributes private Device _graphicsDevice; private Sprite _spriteManager; private GraphicsSprite gs; #endregion // \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* // GameForm - Properties // \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* #region GameForm - Properties private Device GraphicsDevice { get { return \_graphicsDevice; } set { \_graphicsDevice = value; } } private int ScreenWidth { get { return 1024; } } private int ScreenHeight { get { return 768; } } public Sprite SpriteManager { get { return \_spriteManager; } set { \_spriteManager = value; } } #endregion // \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

Nice, it works :) The function: private int WrapValue( int val, int lowerBound, int upperBound ) { int result = lowerBound + ( val - lowerBound ) % ( upperBound - lowerBound ); if( result < lowerBound ) { result += ( upperBound - lowerBound ); } return result; } I tried it with all different bounds and values and it works great. Thanks a ton :)

Hi, I've for a similar problem I have a Volume Control that only has values from 0 to 100 and i want to replace a slider control that ranges from -12 to 12??? any help please! J.Feeke:confused:
