visual c++ - stop video preview using directshow in vc++ -

-

.. I just wrote the application for the preview show for the user and the capture graphor filter for capture image Image using Pin.PREEPE Pin User For Preview Video Only going good. But when I close the preview it has an effect on the capture capture capture image

I am using the control stream for stop preview.

pl Please help

To use a solution, you can add several graphs together and control them independently can do. In this way, you can get 3 graphs, which connects your source with two sinks: 

  source - (capture pin) - & gt; Capture Sync - (Preview Pin) - & gt; Preview Sync

For a preview: 

  Preview Source - & gt; Renderer

and to capture the other: 

  Capture Source - & gt; Sample Strike

Using GMFBridge, you can hook Capture Sync to Capture Source and Preview Sync to Preview Source. Once this happens, you can start or stop the preview graph without affecting the capture graph, and vice versa. Hopes

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
