संभावित डुप्लिकेट:

हालांकि मुझे पता है कि फैक्टरी डिजाइन पैटर्न क्या है लेकिन मैं यह समझने में असमर्थ हूं कि इसका उपयोग करने के क्या लाभ हैं फ़ैक्टरी डिजाइन पैटर्न का उपयोग करके हम वस्तुओं को क्यों बनाते हैं।

कारखानों के माध्यम से ऑब्जेक्ट बनाने से, आप सबसिस्टम यह कोड इंटरफेस के विशिष्ट कार्यान्वयन पर निर्भर करता है - "एक इंटरफेस के लिए प्रोग्राम, कार्यान्वयन के लिए नहीं" "डिजाइन पैटर्न" पुस्तक में सबसे महत्वपूर्ण एकल वाक्यांश है, और कारखाने आपके कोड को उस उत्कृष्ट दिशा में स्थानांतरित करने का एक महत्वपूर्ण तरीका है लक्ष्य (निर्भरता इंजेक्शन इसके लिए एक और प्रमुख डीपी है, जो कि क्लासिक किताब में शामिल नहीं है - लेकिन फिर, अक्सर निर्भरताएं जो आप हैं कारखानियां किसी भी तरह से, इसलिए कि चूक बहुत भयानक नहीं है ;-)

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session .

This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page.

The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .

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...
