iphone - Asynchronous IO with CFWriteStream -

-

मैं सीएफड्राइटस्ट्रीम शेड्यूल्यूथ रीनल लूप और सीएफड्राइटस्ट्रीम वाइट का उपयोग एसिंक्रोनस आईओ करने के लिए कर रहा हूँ। यहाँ प्रश्न है: ऐसा लगता है कि केवल एक CFWriteStreamWrite कॉल सुरक्षित है (ब्लॉकिंग से मुक्त) प्रति प्रत्येक kCFStreamEventCanAcceptBytes अधिसूचना, क्योंकि दूसरे कॉल से, हम गारंटी नहीं दे सकते कि सॉकेट अधिक डेटा स्वीकार करने के लिए तैयार है। इसलिए यदि हम n CFWriteStreamWrite कॉल करना चाहते हैं, तो हमें "केसीएफस्ट्रीमइवेंटकैनएक्सेप्टबाइट्स" और "कॉलिंग CFWriteStreamWrite" एन बार दोहराना होगा।

क्या यह सही है?
धन्यवाद!

< दूसरे प्रश्न के समान उत्तर: call cfwritestreamCanAcceptBytes () स्ट्रीम पर देखने के लिए कि क्या यह है कि / div>

अभी भी उस पर लिखना सुरक्षित है।

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

session - security issue: php login/logout script + back button -

-
I am using a login script that stores session value $ _ Session ['Login' '] =' Yes' On logout, when the user enters the correct user / password, this session value is set to an empty space. However users can back up and log back in for some time. I also tried $ _SESSION = array (); And session_destroy (); But with the same result. Does they actually log back in, or do they reload pages only Cache? If it's only a cache, they will not be able to see the page that was not before, and they will not be able to see new data on your site. If they are actually logging back in, then your login code is bad on each page on the login page and login page.
