WPF Architecture and Direct3D graphics acceleration -

-

After reading the WPF architecture, I am confused with the little benefit that WPF will provide me (Wikipedia is a good search reference Is not, but I have found this useful). I have some questions

1) WPF uses 3D render to surfaces. However, the viewer is provided by the media integrated layer in the D3 Surface, which runs on the CPU. is it true?

2) I just have a question that do not use bitmap basic resources. Does this mean that if I use a lot of images, then MIL will make every copy, while the text will be copied instead of storing bitmaps on the video card? 3) It has been mentioned in the article that WPF uses penters algorithm which is back in front pain is slow. Is there any logical reason why WPF uses jade-buffering and render to rear? I am guessing because it is the easiest way to handle transparency, but it looks weak.

I think it is thinking that it would not be wise to put hundreds of buttons on one screen for me, colleagues say that it has Direct X accelerator. I do not quite believe that the full Direct X fast speed about WPF I used to work on video games and my memory of writing the D3D and OpenGL code tells me to be alert.

You can check the SDK for Question # 1 and # 3 which discusses and How is it exchanged between the higher framework and the Media Integration Layer (MIL). It also discusses why the painter's algorithm is used.

For # 2, this is definitely not the case at all. Bitmap data will be moved into the hardware and will be cached there.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

kernel - How to create a "Block device" in Windows -

-
For people familiar with Linux, it is possible to create a module and register it as a block device. This allows the user to mount it as a regular disk (whereas all block I / O is controlled by the module, for example USB-MastStorage). Is there a way to do this in windows? (Windows needs to create a volume. Raw data will come from the interface with justification.) Thanks The easiest way (and this is not easy!) Is to write one, you can do it also with KMDF. The latest issue of the "NT Insider" of the OSR is an article in how to do this, but it not is going to be easy anyway You will learn a ton, though, So if you are interested in kernel development, then this is a good way to start!
