    <p>Create your texture from the video frame and then LockRect it and copy the data in. You now have the data in a D3D9 Texture.</p> <p>Loading a pixel shader is easy. Use <a href="http://msdn.microsoft.com/en-us/library/bb172768%28v=vs.85%29.aspx" rel="nofollow">D3DXCreateEffectFromFile</a>.</p> <p>Rendering a quad with a texture on it can easily be learnt by looking at any tutorial on the internet. Try this one:</p> <p><a href="http://www.drunkenhyena.com/cgi-bin/view_cpp_article.pl?chapter=2;article=30" rel="nofollow">http://www.drunkenhyena.com/cgi-bin/view_cpp_article.pl?chapter=2;article=30</a></p> <p>If you set it up right the effect will automatically be applied to the quad.</p> <p>Edit: From looking at your code it appears you don't set the world, view or projection matrices. Nor do you set your viewport.</p> <p>Firstly you should set them all the matrices to identity. This means that the vertices you pass in will shift through the pipeline without any changes. You then need to bear in mind that the "projection" space runs from -1 to 1 (left to right bottom to top).</p> <p>Therefore your need to define your quad as follows:</p> <pre><code>ver[0] = new CustomVertex.PositionTextured(-1, 1, 0, 0, 0); ver[1] = new CustomVertex.PositionTextured(1, 1, 0, 1, 0); ver[2] = new CustomVertex.PositionTextured(-1, -1, 0, 0, 1); ver[3] = new CustomVertex.PositionTextured(1, 1, 0, 1, 0); ver[4] = new CustomVertex.PositionTextured(1, -1, 0, 1, 1); ver[5] = new CustomVertex.PositionTextured(-1, -1, 0, 0, 1); </code></pre> <p>You then need to set your viewport as follows (This is a C++ Viewport set as i haven't really used C# much):</p> <pre><code>D3DVIEWPORT9 vp; vp.X = 0; vp.Y = 0; vp.Width = 1920; vp.Height = 1080; vp.MinZ = 0.0f; vp.MaxZ = 1.0f; pDevice-&gt;SetViewport( &amp;vp ); </code></pre> <p>At this point I would expect to see the whole texture on screen.</p> <p>Btw Im also not entirely sure what you are doing in the SetTextureStageState ... Are you just saying "Select Arg1". Are you passing in the equivalent of D3DTA_TEXTURE to COLOR ARG 1?</p>

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.
