    <p>You could use a <code>RenderTarget</code>to achieve your goal. It sounds like you don't want to have to render accordingly to every possible screen size, so if your graphics aren't dependant on other graphical features like a mouse, then I would use a <code>RenderTarget</code> and draw all the pixel data to that and afterwards draw it to the actual screen allowing the screen to stretch it.</p> <p>This technique can be used in other ways too. I use it to draw objects in my game, so I can easily change the rotation and location without having to calculate every sprite for the object.</p> <p>Example:</p> <pre><code>void PreDraw() // You need your graphics device to render to GraphicsDevice graphicsDevice = Settings.GlobalGraphicsDevice; // You need a spritebatch to begin/end a draw call SpriteBatch spriteBatch = Settings.GlobalSpriteBatch; // Tell the graphics device where to draw too graphicsDevice.SetRenderTarget(renderTarget); // Clear the buffer with transparent so the image is transparent graphicsDevice.Clear(Color.Transparent); spriteBatch.Begin(); flameAnimation.Draw(spriteBatch); spriteBatch.Draw(gunTextureToDraw, new Vector2(100, 0), Color.White); if (!base.CurrentPowerUpLevel.Equals(PowerUpLevels.None)) { powerUpAnimation.Draw(spriteBatch); } // DRAWS THE IMAGE TO THE RENDERTARGET spriteBatch.Draw(shipSpriteSheet, new Rectangle(105,0, (int)Size.X, (int)Size.Y), shipRectangleToDraw, Color.White); spriteBatch.End(); // Let the graphics device know you are done and return to drawing according to its dimensions graphicsDevice.SetRenderTarget(null); // utilize your render target finishedShip = renderTarget; } </code></pre> <p>Remember, in your case, you would initialize your <code>RenderTarget</code> with dimensions of 568x320 and draw according to that and not worry about any other possible sizes. Once you give the <code>RenderTarget</code> to the spritebatch to draw to the screen, it will "stretch" the image for you!</p> <p>EDIT: </p> <p>Sorry, I skimmed through the question and missed that you don't want to "stretch" your result. This could be achieved by drawing the final <code>RenderTarget</code> to your specified dimensions according to the graphics device. </p>

    1. COMy bad, i've miss explain my problem. Let's try again : All graphics are pixel art (in resolution 568x320, not matter, it could have been another one). But this resolution is too small to play, so the player can switch resolution to a "zoomed" one. If i use Matrix transformation, or renderTarget my graphics are blurred; in case of 2x zoom (in other word, 1136x640) all pixels of assets are duplicated a second time on each axe, to preserve the pixel art aspect (take a look on hydorah to well understand (freeware)).

    2. COHmm, Really, the only practical solution I see then for that would be to have larger sprites...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
