c# - Problems submitting DataGridView changes with Linq-to-SQL -

-

मैं एक DataGridView नियंत्रण के माध्यम से डेटाबेस मान संस्करण कार्यान्वित करने की कोशिश कर रहा हूं, लेकिन ईमानदारी से मैं कर रहा हूँ यह पूरा करने की कोशिश कर रहे एक कठिन समय मैं मूल रूप से LINQ-to-SQL वर्गों और घटनाओं का उपयोग कर रहा हूं, निम्नलिखित सबसे महत्वपूर्ण स्निपेट्स हैं: 

  var डेटा = डेटा से q.FOOBARS नई {ID = q.FOOBAR_ID का चयन करें, LOREM = q.FOOBAR_LOREM, आईपीएसयूएम = q.FOOBAR_IPSUM}; डेटाग्रीड दृश्य ग्रिड = नया डेटाग्रिड दृश्य (); ग्रिड। डेटा स्रोत = डाटा; // ग्रिड ईवेंट निजी शून्य grid_CellDoubleClick (ऑब्जेक्ट प्रेषक, DataGridViewCellEventArgs ई) {this.grid.CurrentCell.ReadOnly = false; this.grid.BeginEdit (सही); } निजी शून्य grid_CellLeave (वस्तु प्रेषक, DataGridViewCellEventArgs ई) {if (this.grid.CurrentCell.IsInEditMode) {// विधि कॉल this.SetVariableValue (this.grid.CurrentRow.Cells [ "आईडी"]। Value.ToString (), this.grid.CurrentCell.OwningColumn.Name, this.grid.CurrentCell.FormattedValue.ToString (), this.grid.CurrentCell.EditedFormattedValue.ToString ()); } This.grid.CommitEdit (DataGridViewDataErrorContexts.Commit); this.grid.EndEdit (); } // विधि IMPL निजी शून्य SetVariableValue (स्ट्रिंग आईडी, स्ट्रिंग प्रकार, स्ट्रिंग वर्तमान, स्ट्रिंग संपादित) {{अगर (वर्तमान! = संपादित) {का उपयोग कर (FOOBARDataClassesDataContext डेटा = नए FOOBARDataClassesDataContext (this.BuildConnection ())) {डेटा प्रयास करें। ExecuteCommand ("एसईटी हस्तांतरण अवकाश स्तर पढ़ा गया संयुक्त राष्ट्र"); स्विच (प्रकार) {मामले "lorem":। वर currentLorem = data.FOOBARS.SingleOrDefault (v = & gt; v.FOOBAR_ID == Convert.ToInt32 (आईडी)) FOOBAR_LOREM; CurrentLorem = संपादित; data.SubmitChanges (ConflictMode.ContinueOnConflict); टूटना; मामले "ipsum": var currentIpsum = data.FOOBARS.SingleOrDefault (v = & gt; v.FOOBAR_ID == Convert.ToInt32 (आईडी)) FOOBAR_IPSUM;। CurrentIpsum = संपादित; data.SubmitChanges (ConflictMode.ContinueOnConflict); टूटना; डिफ़ॉल्ट: ब्रेक; } डेटा। रीफ़्रेश करें (रिफ्रेशमोड। ओवरराइट कंटेंट वाल्व); }}} पकड़ (अपवाद त्रुटि) {यदि (logger.IsErrorEnabled) लॉगर। त्रुटि (error.Message); }}

डिबगिंग अच्छा लगता है, ऑब्जेक्ट वास्तव में अद्यतन हो रहे हैं लेकिन कुछ कारणों से परिवर्तन न तो सबमिट किए गए हैं या न ही अपडेट किए जा रहे हैं।

कोई भी मदद निश्चित रूप से सराहना की जाएगी। बहुत से लोग अग्रिम धन्यवाद!

किसी कारण से यह काम नहीं करता : 

  वर currentLorem = data.FOOBARS.SingleOrDefault (v = & gt; v.FOOBAR_ID == Convert.ToInt32 (आईडी)) FOOBAR_LOREM;। CurrentLorem = संपादित; data.SubmitChanges (ConflictMode.ContinueOnConflict);

लेकिन यह नहीं है (पंक्ति 1 और 2, फ़ूबर_लार्म विशेषता में बदलाव देखें): 

  var currentLorem = डेटा फूबर्स। सिंगलऑर डीफॉल्ट (v = & gt; v.FOOBAR_ID == कन्वर्ट.ओआईएनटी 32 (आईडी)); CurrentLorem.FOOBAR_LOREM = संपादित; data.SubmitChanges (ConflictMode.ContinueOnConflict);

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...
