Iphone device token - NSData or NSString -

-

I am receiving the iPhone Device Token as the NSData object when I Tested the notification script function, so I only copied that object from the log and the notifications were fixed. But when I try to do it automatically, I am sending the instrument token as an ASCII encoded string in the form of 

  self.deviceToken = [[NSString Alloc] initWithData: webDeviceToken encoding: NSASCIIStringEncoding];

The string I find is some funky characters and it looks like

when the server side script notifications Sends that token, I have not got anything.

Do I need to decode anything else?

Regards

OK, I got a solution if anyone If the problem is, forget about ASCII encoding, just string with the following lines: 

  NSString * deviceToken = [[webDeviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInstring: @ "& lt; & Gt; "]]; DeviceToken = [DeviceToken stringBeerplugging occurenceoffstring: @ "" with string: @ ""];

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!
