I am having a problem creating a 3D Texture from a Memory Stream. Here is what I am doing. //* xTmpImage is initilized and loads a bmp file elsewhere System.Drawing.Bitmap xTmpImage xImageStream = new System.IO.MemoryStream(); xTmpImage.Save( xImageStream, ImageFormat.Bmp ); xTmpTexture = TextureLoader.FromStream( GrafixEnv.Device, xImageStream, xImageStream.Length); When the FromStream function executes I get the following errors ManagedDX: The HRESULT 0x88760b59 was returned (D3DXERR_INVALIDDATA). Please turn on unmanaged debugging for more information. An unhandled exception of type 'Microsoft.DirectX.Direct3D.InvalidDataException' occurred in microsoft.directx.direct3dx.dll Additional information: Error in the application. I have double checked all of the parameters and they are all initilied and valid. When I try to create the texture from a file it works ok. The only thing that I can think of is the BMP file written to the memory stream is somehow missing some data. Thanx in advance for the help.

What you are doing looks okish. Don't know why its beraking. If I were in your place I would just use the Texture constructor that takes a bitmap as a parameter.

If you are set on using a stream the way you are you may have to seek the beginning of the stream (using Seek() or Position = 0) when you are done writing it and before you start reading from it.

That was it. I needed to manually set the stream position to 0 before creating the texture. Once I did that, everything worked ok.
