C# - How to test at runtime which COM coclass was used to instantiate an interface? -

-

मान लें कि आपके पास एक COM इंटरफ़ेस ICOMInterface है जो कोकलेस Coclass1 और कोक्लास 2 । इन कॉकलेसों में से किसी भी अपने स्वयं के इंटरफेस नहीं हैं (सादगी के लिए और मेरी समस्या को स्पष्ट करने के लिए)।

सी # में, आप एक कॉकैस से COM अंतरफलक का एक उदाहरण बना सकते हैं जैसे:

< पूर्व> ICOMInterface myComInterface = नया Coclass1 ();

अब, आप यह कैसे निर्धारित कर सकते हैं कि myComInterface को Coclass1 या Coclass2 ?

जैसे "है" कथन का प्रयोग करना हमेशा सही होता है, और इस प्रयोजन के लिए बेकार है। 

  डीबग। विरাইটलाइन (मेरी कॉमइंटरफेस कोक्लस 1 है) // "सत्य" डीबग लिखता है .इटइटलाइन (मेरा कॉमइंटरफ़ाइड कोक्लस 2 है) / लिखता है "सच"

यह काम करेगा अगर मैं इंटरफेस का परीक्षण कर रहा था, कोकलेस नहीं, लेकिन इन कोकलेसों में उनके दोनों के कार्यान्वयन के अलावा अन्य इंटरफेस नहीं हैं , ICOMInterface ।

मुझे उम्मीद है कि इस सामान्य परिदृश्य का एक सरल जवाब है जो मैं देख रहा हूं, अन्यथा मैं अधिक विशिष्ट विवरण पोस्ट कर सकता हूं यदि आवश्यक हो।

आपकी मदद के लिए धन्यवाद!

यदि COM ऑब्जेक्ट इंटरफ़ेस लागू करता है, तो आप इसके सीएलएसआईडी प्राप्त कर सकते हैं आईपरर्सिस्ट :: GetClassID () विधि के माध्यम से यह जानने के लिए आप सभी की जरूरत हो सकती है कि आप किस वर्ग के साथ काम कर रहे हैं आप WinAPI ProgIDFromCLSID () विधि के माध्यम से मानव-वाचनीय प्रोजेड भी प्राप्त कर सकते हैं।

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 . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
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. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. 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...
