Is there any way to draw Webbrowser content to a specific DC?

Question

These days, I tries to create a hiden WebBrowser control in my program, and Using the IViewObject interface draw to my custom DC.

The result is fine, I got All the content I want, but the Draw speed is unacceptable, especially some complex web pages which contains Flash objects, Each Draw to DC cost more than 100 ms. So the flash object I drew is not smooth.

Is there a fast way to draw the control to my a specific DC?

my code sinpet is like this:

//hCompDc is a CompatibleDC which select a CompatibleBitmap.
RECTL imageRect = {0, 0, nWidth, nHeight};
pHtmlDocument2->QueryInterface(IID_IViewObject, (void **)&pViewObject);
pViewObject->Draw(DVASPECT_CONTENT, -1, NULL, NULL, NULL, hCompDc, NULL, &imageRect, NULL, 0);

Thank you for reading this question.

Waiting for your answers~

There is no other way to do this. None of the components you're using--IE, Flash, etc--were designed to be used this way. If draw time is an issue, you have to do it on a separate thread and synchronize.
