    <p>How can i make screenshoots to the entire game screen very fast? Somthing like 20-30 per second?(i want to convert them to video)</p> <p>[[1]] I've tried WMEncoder.Results were that WMEncoder can capture the screen and regions of screen only in a video format (wma) using a set of preconfigured codecs. (29 fps best encode result).WMEncoder can not make screenshots.</p> <p>[[2]] I've tried DirectX :</p> <pre><code>Surface s = device.CreateOffscreenPlainSurface( Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, Format.A8R8G8B8, Pool.SystemMemory); device.GetFrontBufferData(0, s); SurfaceLoader.Save("c:\\Screenshot"+i.ToString()+".bmp", ImageFileFormat.Bmp, s); </code></pre> <p>This works like gdi ..very slow....and it works only in DirectX 1.0 because SurfaceLoader does not exist in directX 2.0</p> <p>Another way that i've read in some post is using :</p> <pre><code>s = device.GetBackBuffer(0, 0, Microsoft.DirectX.Direct3D.BackBufferType.Mono); </code></pre> <p>, but this maks screenshots only to the curent window.</p> <p>[[3]] I've tried to use Taksi (at sourceforge.net)... but i don't know how to use it in c# and make it work.</p> <p>Please help me out...</p>

    2. COYou mentioned GDI, did you use `Bitblt` or the `System.Drawing` namespace? It's a huge difference in performance.

    3. COSo you don't want to take video, just because of performance issues (don't know will it affect perf.)? Convert them after the rest of the work? I wonder why you just take video, it will be simpler. EDIT: I saw your another question is to take video. That's strange, I think people interest in screencapturing more than taking video.

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.
